Squamous cell carcinoma of the oral mucosa after release of submucous fibrosis and bilateral small radial forearm flap reconstruction

Oral submucous fibrosis is a collagen disorder that affects the submucosal layer of the upper digestive tract. The major cause is the habit of betel quid chewing, which is common in central, southern, and southeast Asia. The progressive and irreversible course of disease results with trismus, dysphagia, xerostomia, and rhinolalia. The most serious complication of this disorder is the development of oral carcinoma, and the incidence in different series varies from 1.9 to 10 percent. A sufficient mouth opening can be achieved by complete release of fibrotic tissue, and coronoidectomy and temporal muscle myotomy when needed, and reconstruction of the resultant defect can be best achieved by microsurgical free-tissue transfer because of the discouraging results with skin grafting or local flaps. From April of 1997 to May of 2001, a total of 26 patients received reconstructive surgery with small radial forearm flaps after release of submucous fibrosis with or without temporalis muscle myotomy and coronoidectomy. All patients were men, with a mean age of 40.1 years (range, 18 to 62 years) and all had a history of betel nut chewing ranging from 8 to 40 years. The interincisal distance ranged from 5 to 29 mm, with a mean of 15 mm, before operation. After the release procedure, the interincisal distance increased to 40 mm (range, 35 to 50 mm). At a follow-up period of 3 to 48 months, the interincisal distance was a mean of 35 mm (range, 18 to 57 mm), with an average increase of 20 mm compared with the preoperative distance. During follow-up, three patients developed squamous cell carcinoma of the oral cavity 24 to 36 months after submucous fibrosis release. Two of them occurred in the release site and the other one occurred at the soft palate. Oral cancer occurred in three of 13 patients who had received release of submucous fibrosis and who were followed for longer than 2 years (range, 24 to 48 months), which means that 23 percent of these patients developed squamous cell carcinoma of the intraoral mucosa. High risk of cancer occurrence strongly indicates the importance of an earlier and more aggressive surgical approach toward submucous fibrosis, and long-term follow-up on a regular basis. The purpose of an early and aggressive approach to submucous fibrosis is to provide a good quality of life to the patient by improving oral hygiene and oral intake quality and at the same time to obtain a sufficient mouth opening, which is mandatory for the inspection of the excision site and the remaining oral mucosa during follow-up.     

Importance of coronoidotomy and masticatory muscle myotomy in surgical release of trismus caused by submucous fibrosis

Thirty patients with trismus resulting from betel nut chewing-induced oral submucous fibrosis were treated with either fibrotic tissue release only (group I) or fibrotic tissue release in combination with masticatory muscle myotomy and coronoidotomy (group II). The latter procedures were only performed in patients whose intraoperative interincisal distance remained less than 35 mm immediately after submucous fibrous tissue release. There were eight and 22 patients in groups I and II, respectively. In group I patients, the average intraoperative interincisal distance improved from 19.5 mm to 42 mm. In group II patients, the average intraoperative interincisal distance improved from 13.5 mm to 27 mm after fibrotic tissue release and further improved to 40 mm after masticatory muscle myotomy and coronoidotomy. At an average follow-up of 22.1 months (range, 7 to 70 months), the group I and II patients had an average interincisal distance of 41.5 mm (range, 35 to 50 mm) and 32.9 mm (range, 20 to 42 mm), respectively. These results demonstrate the efficacy of submucous fibrotic tissue release in treating trismus resulting from betel nut chewing-induced submucous fibrosis and confirm the role of additional masticatory muscle and coronoidotomy in treating its severe forms.     

Neuromucosal prelaminated flaps for reconstruction of intraoral lining defects after radical tumor resection

To reconstruct intraoral lining defects after radical tumor resection by reinnervated vascularized mucosa, eight distal radial forearm flaps and two fibula flaps were prelaminated. Prelamination was performed by exposing the vascularized fascia, onto which the split distal end of a sural graft was fixed. The fascia and the sural nerve graft were covered by device-meshed mucosa or small full-thickness mucosa pieces. These structures again were covered by a Silastic sheet as large as the future flap, and the wound was closed by the elevated skin and subcutaneous tissue. Coverage by a Silastic sheet enabled mucosal spreading on the fascia, and the final flaps were thin, mucus-producing, and larger than the originally inserted mucosa. The 10 neuromucosal prelaminated flaps were harvested together with the inserted sural nerve graft after 8 to 10 weeks. During this time, the patient underwent radiotherapy and chemotherapy. Donor sites were closed directly by the preserved skin and subcutaneous tissue. Intraoral defects were reconstructed successfully by eight neuromucosal prelaminated distal radial forearm flaps and two neuromucosal prelaminated fibula flaps. The sural nerve grafts, inserted between the fascia and the mucosa, were coaptated eight times with the lingual nerve and two times with the inferior alveolar nerve. Intended reinnervation of the mucosa could already be proved clinically and histologically in the first two patients after 11 and 9 months. Preservation of skin and subcutaneous tissue considerably lowered donor-site morbidity. Neuromucosal prelamination enables reconstruction of intraoral lining defects by reinnervated mucus-producing tissue. Reconstruction of other mucosa-lined structures by this method seems feasible. Avoidance of skin islands for reconstruction lowers donor-site morbidity.     

Multipaddled Anterolateral Thigh Chimeric Flap for Reconstruction of Complex Defects in Head and Neck

The anterolateral thigh flap has been the workhouse flap for coverage of soft-tissue defects in head and neck for decades. However, the reconstruction of multiple and complex soft-tissue defects in head and neck with multipaddled anterolateral thigh chimeric flaps is still a challenge for reconstructive surgeries. Here, a clinical series of 12 cases is reported in which multipaddled anterolateral thigh chimeric flaps were used for complex soft-tissue defects with several separately anatomic locations in head and neck. Of the 12 cases, 7 patients presented with trismus were diagnosed as advanced buccal cancer with oral submucous fibrosis, 2 tongue cancer cases were found accompanied with multiple oral mucosa lesions or buccal cancer, and 3 were hypopharyngeal cancer with anterior neck skin invaded. All soft-tissue defects were reconstructed by multipaddled anterolateral thigh chimeric flaps, including 9 tripaddled anterolateral thigh flaps and 3 bipaddled flaps. The mean length of skin paddle was 19.2 (range: 14–23) cm and the mean width was 4.9 (range: 2.5–7) cm. All flaps survived and all donor sites were closed primarily. After a mean follow-up time of 9.1 months, there were no problems with the donor or recipient sites. This study supports that the multipaddled anterolateral thigh chimeric flap is a reliable and good alternative for complex and multiple soft-tissue defects of the head and neck.     

Reconstruction of concomitant lip and cheek through-and-through defects with combined free flap and an advancement flap from the remaining lip

Massive facial defects involving the oral sphincter are challenging to the reconstructive surgeon. This study presents the authors' approach to simultaneous reconstruction of complex defects with an advancement flap from the remaining lip and free flaps. From January of 1997 to December of 2001, 22 patients were studied following ablative oral cancer surgery. Their ages ranged from 32 to 66 years. Nineteen patients had buccal cancer, two patients had tongue cancer, and one patient had lip cancer. In all cases, the disease was advanced squamous cell carcinoma. Nine patients underwent composite resection of tumor with segmental mandibulectomy, and seven patients underwent marginal mandibulectomy. Cheek defects ranged from 15 x 12 cm to 4 x 3 cm, and intraoral defects ranged from 14 x 8 cm to 5 x 4 cm in size. One third of the lower lip was excised in nine patients, both the upper and lower lips were excised in 10 patients, and only commissure defects were excised in three patients. An advancement flap from the remaining upper lip was used for reconstruction of the oral commissure and oral sphincter. Then, the composite through-and-through defect of the cheek was reconstructed with radial forearm flaps in 13 patients, fibula osteocutaneous flaps in five patients, double flaps in three patients, and an anterolateral thigh flap in one patient. The free flap survival rate was 96 percent, and only one flap failed. With regard to complications, there were two patients with cheek hematoma, six patients with orocutaneous fistula or neck infection, and one patient with osteomyelitis of the mandible. All but one patient had adequate oral competence. All patients had an adequate oral stoma and could eat a regular or soft diet; two patients could eat only a liquid diet. For moderate lip defects, immediate reconstruction of complex defects took place using an advancement flap from the remaining lip to obtain a normal and functional oral sphincter; the free flap can be used to reconstruct through-and-through defects. This simple procedure can provide patients with a useful oral stoma and acceptable cosmesis.     

Prelaminating the fascial radial forearm flap by using tissue-engineered mucosa: improvement of donor and recipient sites.

In reconstructive surgery, prelamination of free flaps using split-thickness skin is an established technique to avoid the creation of a considerable defect at the donor site, for example, in the case of a radial forearm flap. For oral and maxillofacial surgery, this technique is less than optimal for the recipient site because the transferred skin is inadequate to form a lining in the oral cavity. To create mucosa-lined free flaps, prelamination using pieces of split-thickness mucosa has been performed. However, the availability of donor sites for harvesting mucosa is limited. The present study combines a tissue-engineering technique with free flap surgery to create mucosa-lined flaps with the intention of improving the tissue quality at the recipient site and decreasing donor-site morbidity. On five patients undergoing resection of squamous cell carcinoma of the oral cavity, the radial forearm flap was prelaminated with a tissue-engineered mucosa graft to reconstruct intraoral defects. Using 10 x 5 mm biopsies of healthy mucosa, keratinocytes were cultured for 12 days and seeded onto collagen membranes (4.5 x 9 cm). After 3 days, the mucosal keratinocyte collagen membrane was implanted subcutaneously at the left or right lower forearm to prelaminate the fascial radial forearm flap. One week later, resection of the squamous cell carcinoma was performed, and the free fascial radial forearm flap pre- laminated with tissue-engineered mucosa was transplanted into the defect and was microvascularly anastomosed. Resection defects up to a size of 5 x 8 cm were covered. In four patients, the graft healed without complications. In one patient, an abscess developed in the resection cavity without jeopardizing the flap. During the postoperative healing period, the membrane detached and a vulnerable pale-pink, glassy hyperproliferative wound surface was observed. This surface developed into normal-appearing healthy mucosa after 3 to 4 weeks. In the postoperative follow-up period, such functions as mouth opening and closing and speech attested to the success of the tissue-engineering technique for flap prelamination.     

Primary closure of radial forearm flap donor defects with a bilobed flap based on the fasciocutaneous perforator of the ulnar artery

To primarily repair a series of radial forearm flap donor defects, a total of 10 bilobed flaps based on the fasciocutaneous perforator of the ulnar artery were designed at the Chang Gung Memorial Hospital in Kaohsiung in the period from January of 2002 to January of 2003. All patients were male, with ages ranging from 36 to 67 years. The forearm donor defects ranged in size from 5 x 6 cm to 8 x 8 cm, with the average defect being 47 cm. One to three sizable perforators from the ulnar artery were consistently observed in the distal forearm and were most frequently located 8 cm proximal to the pisiform, which could be used as a pivot point for the bilobed flap. The bilobed flap consisted of two lobes, one large lobe and one small lobe. With elevation and rotation of the bilobed flap, the large lobe of the flap was used to repair the radial forearm donor defect and the small lobe was used to close the resultant defect from the large lobe. All bilobed flaps survived completely, without major complications, and no skin grafting was necessary. Compared with conventional methods for reconstruction of radial forearm donor defects, such as split-thickness skin grafting, the major advantage of this technique is its ability to reconstruct the donor defect with adjacent tissue in a one-stage operation. Forearm donor-site morbidity can be minimized with earlier hand motion, and better cosmetic results can be obtained. Furthermore, because a skin graft is not used, no additional donor area is necessary. However, this flap is suitable for closure of only small or medium-size donor defects. A lengthy postoperative scar is its major disadvantage.     

A new surgical procedure for phallic reconstruction: Istanbul flap

A new surgical procedure is described for phallic reconstruction, which still remains a great challenge in reconstructive surgery. In this procedure, an osteocutaneous radial forearm flap is combined with a radial recurrent fasciocutaneous flap from the anterolateral aspect of the upper arm. While keeping a fasciovascular connection between them, both flaps are elevated as a combined free flap based on the radial artery. The forearm skin island is used solely to construct the outer skin cover of the phallic shaft, and the neourethra is created by using the radial recurrent flap. Over the past 4 years, this surgical procedure, termed the Istanbul flap, has been used successfully for complete phallic reconstruction in five patients. Although more clinical experience with this new technique is needed, it seems to be a useful alternative in phallic reconstruction. It remarkably minimizes the donor-site scar without sacrificing the length of the neopenis. In addition, this technique reduces the risk of a hairy urethra.     

Bilateral cleft lip reconstruction

Over a period of 8 years 140 bilateral cleft lips were operated using a muscle-repositioning banked fork-flap cheiloplasty. The use of buccal mucosal flaps in the intercartilaginous incision is helpful to decrease scarring and contracture by facilitating alar cartilage repositioning and wound closure without tension. Adding mucosa from the inferior turbinate makes complete wound closure relatively easy without tension. A lateral lip orbicularis muscle flap with white skin roll and vermilion is recommended for reconstruction of the Cupid's bow. Muscle continuity by freeing the muscle in one sheet and repositioning in front of the premaxilla with creation of a buccal alveolar sulcus is stressed to prevent the necessity of reentering the lip in a second procedure. The elongation of the columella is done at 1 to 6 years of age by advancing nasal floor tissue onto the columella and repositioning the alar cartilages superiorly and medially. When nasal floor tissue is inadequate, columellar lengthening is done by the use of a composite free ear graft.     

Three-dimensional reconstruction of the oral cavity using the free anterolateral thigh flap.

Oral cavity reconstruction after removal of locally advanced tumors is particularly difficult because anatomical restoration must accurately reproduce the original structure and enable effective and fast rehabilitation of mastication, swallowing, and phonation. The authors report their 2-year experience with 17 patients surgically treated for oral cavity cancer with reconstruction performed with the free anterolateral thigh flap. Thanks to its thinness and pliability, this flap has proven to be perfectly adaptable to the structural peculiarities of the resected areas and has enabled the authors to considerably reduce the cosmetic and functional complications in the donor area observed with other flaps (such as the radial forearm flap). Flap grafting has always been complete and regular, and no intraoperative and postoperative complications have been observed. Swallowing recovery has always been satisfactory. On the basis of the authors' results, their current approach to oral cavity reconstruction is based on the use of flaps that enable anatomical restoration of the resected areas and reduce morbidity of the donor site. They believe that the anterolateral thigh flap can offer all of these opportunities, and the surgery can be simultaneously performed by two surgical teams.     

Microsurgical reconstruction in recurrent oral cancer: use of a second free flap in the same patient

Primary microsurgical reconstruction is the treatment of choice for ablative defects of oral carcinoma. As a result of this trend, more and more patients with recurrent oral carcinoma who have been initially treated with surgical excision and reconstructed with free flaps are being seen. However, a second microsurgical reconstruction attempt in these cases raises questions about the flap choices, availability of recipient vessels, and effects of previous treatment modalities. Herein, 35 patients with perioral carcinoma who had two successive tumor resections and reconstruction with free flaps on each occasion are presented. A total of 75 free tissue transfers were carried out for the first and second reconstructions. After the first tumor resection, 28 radial forearm fasciocutaneous flaps, 7 fibula osteoseptocutaneous flaps, 1 iliac osteomyocutaneous flap, and 2 rectus abdominis myocutaneous flaps were used. For reconstruction after the recurrence, 17 radial forearm fasciocutaneous flaps, 13 fibula osteoseptocutaneous flaps, 3 rectus abdominis myocutaneous flaps, 2 anterolateral thigh flaps, 1 jejunum flap, and 1 tensor fasciae latae flap were used. More vascularized bone transfers were performed during the second reconstruction since the excision for the recurrence frequently required segmental mandibulectomy. The complete flap survival rate was 97.3 percent and 94.6 percent with a reexploration rate of 7.9 percent and 13.5 percent for the first and second free tissue transfers, respectively. The mean follow-up time throughout the procedures was 37.5 months. Disease-free interval between reconstructions was 20.8 months. At the time of evaluation, 54.3 percent of the patients were surviving an average of 19 months since the second reconstruction. The results suggest that free flaps represent an important option in reconstruction of recurrent perioral carcinoma cases undergoing reexcision. When used in this indication they are as safe and effective as the initial procedure.     

Total lower lip reconstruction with a composite radial forearm-palmaris longus tendon flap: a clinical series

Large, full-thickness lip defects after head and neck surgery continue to be a challenge for reconstructive surgeons. The reconstructive aims are to restore the oral lining, the external cheek, oral competence, and function (i.e., articulation, speech, and mastication). The authors' refinement of the composite radial forearm-palmaris longus free flap technique meets these criteria and allows a functional reconstruction of extensive lip and cheek defects in one stage. A composite radial forearm flap including the palmaris longus tendon was designed. The skin flap for the reconstruction of the intraoral lining and the skin defect was folded over the palmaris longus tendon. Both ends of the vascularized tendon were laid through the bilateral modiolus and anchored with adequate tension to the intact orbicularis muscle of the upper lip. This procedure was used in 12 patients. Six patients had cancer of the lower lip, five patients had a buccal cancer involving the lip, and one patient had a primary gum cancer that extended to the lower lip. Total to near-total resection (more than 80 percent) of the lower lip was indicated in six patients. In two other patients, the cancer ablation included more than 80 percent of the lower lip and up to 40 percent of the upper lip. A radial forearm palmaris longus free flap was used in all cases for reconstruction of the defect. Free flap survival was 100 percent. At the time of final evaluation, which was 1 year after the operation, all patients had good oral continence at rest (static suspension) and had achieved sufficient oral competence when eating. Ten patients were able to resume a regular diet, and two patients could eat a soft diet. All patients regained normal or near-normal speech and had an acceptable appearance. The described refinement of the composite radial palmaris longus free flap technique allows the reconstruction of the lower lip with a functioning oral sphincter; the technique can be recommended for patients who need large lower lip resection. It provides functional recovery of the reconstructed lower lip synchronizing with the remaining upper lip.     

Nine-year experience with extended use of the commissure-based buccal musculomucosal flap

This study reports on the extended use of the commissure-based buccal musculomucosal (CBMM) flap. Large lip defects and medium-size intraoral defects have the general problem of being too large for primary closure to avoid a major functional and aesthetic impairment. Elaborate free flaps, such as axial flaps, although excellent in large defects, may not provide mucosa-equivalent sensitivity, motility, volume, and texture to replace lost tissue with a similar kind of tissue. A total of 60 flap procedures were performed with bilateral and unilateral flaps up to 7.5 x 4 cm in size. The partial and total upper and lower vermilion, gingivobuccal sulcus, floor of the mouth, lateral tongue margin, oropharynx, and hard and soft palates were reconstructed. Partial necrosis was seen in four flaps; all patients recovered with good oral function in speech and swallowing, good aesthetics, and prosthetic rehabilitation if necessary. The donor site could be closed primarily. In flaps with dorsal advancement, the mucosal excess above and below was closed, creating two small dog-ears. Facial expression and mouth opening returned to normal after less than 2 months. The parotid duct had to be marsupialized in large flap preparations, but this did never provoke stasis or infection. The two-point sensitivity of the flaps was, on average, equal to that of the nonoperated mucosa in intraindividual correlation, and the flaps lost, on average, 15 percent of their original size. In the authors' estimation, the results indicate a reliable and technically easy option for intraoral, medium-size defect reconstruction that yields sensitivity and facilitates the rehabilitation of oral function in speaking and ingestion.     

Advanced squamous cell carcinoma involving both upper and lower lips and oral commissure with simultaneous reconstruction by local flap: a case report

Introduction

Squamous cell carcinoma is one of the most common malignant tumors of the skin and oral mucosa. However, squamous cell carcinoma involving near total upper and lower lip and oral commissure is rarely seen in the English literature. Simultaneous reconstruction of the upper and lower lips has been inconclusive and presents a challenge to the surgeon. We report such a case and outline our simultaneous reconstruction with local flaps. To the best of our knowledge this has never been reported.

Case presentation

A 73-year-old Thai woman presented with a large rapidly growing squamous cell carcinoma involving the upper lip, lower lip, left oral commissure and left cheek. En bloc resection of upper lip, lower lip, left oral commissure and buccal region was performed. Left radical neck dissection and right modified neck dissection were performed. Reconstruction of the upper lip with a left nasolabial-cheek cervicofacial rotational-advancement flap and right cheek advancement with perialar crescent flap was performed. The lower lip was reconstructed with bilateral labiomental advancement flaps.

Conclusions

Squamous cell carcinoma can grow rapidly and spread along the orbicularis oris muscle and across the oral commissure to the opposite lip. In advanced cancer, multimodal treatment is necessary. No gold standard in the reconstruction of both upper and lower lips has been established. We report the case of an advanced squamous cell carcinoma involving both the upper lip, lower lip, left oral commissure and buccal area and simultaneous reconstruction with local flap coverage that, to the best of our knowledge, has never been reported.     

Comparison of the radial forearm flap and the thinned anterolateral thigh cutaneous flap for reconstruction of tongue defects: an evaluation of donor-site morbidity

The radial forearm flap is commonly used for reconstruction of tongue defects following tumor extirpation. This flap is easy to harvest and offers thin tissue with large-caliber vessels. However, its use leaves behind a conspicuous aesthetic deformity in the forearm and requires the sacrifice of a major artery of that limb, the radial artery. The anterolateral thigh cutaneous flap has found clinical applications in the reconstruction of soft-tissue defects requiring thin tissue. More recently, in a thinned form, the anterolateral thigh flap has been used for reconstructing defects of the tongue with functional results equivalent to that of the radial forearm flap. For the reconstruction of tongue defects, these two flaps could provide similar soft-tissue coverage, but they seem to result in different donor-site appearances. The donor site is closed primarily, leaving only a linear scar that is inconspicuous with normal clothing, and no functional deficit is left behind in the thigh. Thus, for the supply of flaps for tongue defects, a comparison between the radial forearm flap and the anterolateral thigh flap donor sites is provided in this study. Between December of 2000 and August of 2002, 41 patients who underwent reconstruction of defects of the tongue using either a radial forearm flap or an anterolateral thigh flap were evaluated. The focus was on the evaluation of the functional and aesthetic outcome of the donor site after harvesting these flaps for the purpose of reconstructing either total or partial tongue defects. Finally, a comparison was performed between the donor sites of the two flaps. The disadvantages of the radial forearm flap include the conspicuous unattractive scar in the forearm region, pain, numbness, and the sacrifice of a major artery of the limb. In some patients, the donor-site scar of the forearm acted as a social stigma, preventing these patients from leading a normal life. In contrast, the anterolateral thigh cutaneous flap, after thinning, achieved the same results in reconstructing defects of the tongue without the associated donor-site morbidity. Most importantly, the donor site in the thigh could be closed primarily in almost all patients without any functional deficit. The thinned anterolateral thigh cutaneous flap is a viable substitute for the radial forearm flap when reconstructing defects of the tongue. The results achieved are similar to those of the radial forearm flap, and the donor-site morbidity is significantly decreased.     

Perforator flaps from the lateral lower leg for intraoral reconstruction

Perforator flaps are based on cutaneous, small-diameter vessels that originate from a main pedicle and perforate fascia or muscle to reach the skin. Although these flaps have recently become popular for soft-tissue reconstructions in nearly all regions of the body, the systematic application of perforator flaps with short, small-caliber pedicles for intraoral reconstruction has not been reported. Experience with the use of 10 consecutive perforator flaps from the lateral lower leg for intraoral defect coverage is reported. In 10 cases, a 4- to 6-cm-long septocutaneous or myocutaneous perforating vessel from the peroneal artery, with a diameter of 1 to 2 mm, could be identified in the proximal one-half of the lateral lower leg. The thin, pliable skin paddles, measuring up to 6 x 8 cm, were used for defect coverage after resection of squamous cell carcinomas of the floor of the mouth (five cases), soft palate (one case), tongue (two cases), or buccal mucosa (two cases). Anastomoses were performed to the lingual artery and concomitant vein. Except for one case, all perforator flaps healed without complications and the functional results were satisfying. At the donor site, which was always closed directly, an approximately 15-cm-long scar resulted, without functional impairments. The peroneal artery was regularly preserved. Perforator flaps from the lateral lower leg might have many applications for intraoral soft-tissue reconstruction, especially because of their minimal donor-site morbidity.     

Prelaminated free flap reconstruction of complex central facial defects

This article is a review of five patients who underwent reconstruction of nasal and paranasal facial defects with prelaminated forearm free flaps. The defects resulted from thermal injury, gunshot wound, excision of tumor, and arteriovenous malformation (n = 2). The forearm flaps were based on the radial artery (n = 4) and ulnar artery (n = 1) and were prelaminated with grafts of skin and cartilage. All flaps were successfully transferred to the face, but revisions were needed to separate the subunits and improve appearance. A prelaminated free flap should be considered for a patient requiring reconstruction of a complex central facial defect.     

Microsurgical forearm "cricket bat-transformer" phalloplasty.

Presently, the donor flap of choice for microsurgical phallic reconstruction is the radial forearm flap. The success of several different design modifications confirms the reliability of the radial and ulnar forearm flaps. Farrow et al. described their experience with the "cricket bat" concept in 1980. To the previous "cricket bat" design, we now wish to add modifications. These modifications utilize longitudinal and transverse rotations of the linear forearm tissues to create a phallus--much like the transformation of a toy robot into a truck. Deepithelialized flaps and a full-thickness skin graft coronoplasty complete glans reconstruction. The "cricket bat-transformer" flap appears to produce the most predictable results in subtotal phallic reconstructions and phallic constructions in the pediatric and transgender patient groups.     

Bilateral autogenous breast reconstruction using perforator free flaps: a single center's experience

The authors present a single center's experience in bilateral breast reconstruction using perforator free flaps. The aim of this study was to show their indications, surgical technique, and results. A series of 53 patients underwent this procedure between February of 1996 and October of 2002. The surgical procedures were performed on patients with bilateral breast cancer (11 patients), patients with unilateral breast cancer and contralateral prophylactic mastectomy (22 patients), patients who had undergone bilateral prophylactic mastectomy (18 patients), a patient with Poland's syndrome, and a patient whose aesthetic breast augmentation had failed. Primary and secondary bilateral breast reconstructions were done in 18 and four patients, respectively. Eighteen patients who had earlier undergone breast reconstruction with implants had a tertiary breast reconstruction. Combined reconstruction (primary with secondary and primary with tertiary reconstruction) was done in 13 patients. Ninety-eight deep inferior epigastric perforator flaps and eight superior gluteal artery perforator flaps were used. The average operative time was 10 hours (range, 8 to 14.5 hours) for the simultaneous bilateral reconstruction. Total flap necrosis occurred in two cases (one deep inferior epigastric perforator flap and one superior gluteal artery perforator flap). Partial flap necrosis was not encountered, and fat necrosis was found in one deep inferior epigastric perforator flap (1 percent). Two pulmonary infections, one deep vein thrombosis, and one cardiac arrhythmia occurred as postoperative complications. The mean hospital stay was 9 days (range, 6 to 20 days). Abdominal bulging was reported in one patient. There were no recurrent disease or cancer manifestations, with an average follow-up of 3.5 years. This series clearly shows that perforator flaps are reliable and useful tools for bilateral breast reconstruction. This technique decreases the donor-site morbidity and offers an excellent aesthetic and long-term outcome and high patient satisfaction.
