The postauricular fascial flap as an adjunct to Mustardé and Furnas type otoplasty.

Anterior riberation methods of otoplasty have been criticized because of the risk of anterior hematoma that can cause anterior skin necrosis, scarring, and even cartilage destruction caused by infection. As a result, cartilage-sparing otoplasty such as the Mustardé and Furnas types has been increasingly popular. However, postauricular suture extrusion may result, and recurrence rates of up to 25 percent have been recorded. In this study, cartilage-sparing otoplasty is refined by the addition of a postauricular fascial flap to reduce suture extrusion and recurrence rates. Fifty-one patients underwent otoplasty (45 bilateral, six unilateral). This technique involves the elevation of a fascial flap from the postauricular region. A new antihelical fold is then created by Mustardé sutures, and the conchal bowl is rotated by Furnas-type concha-mastoid sutures. The fascial flap is then advanced to cover the sutures with a supplementary vascularized layer to prevent suture extrusion. In addition, the advancement of the flap acts as a postauricular support to prevent recurrence. A natural-looking antihelical fold and helical rim is created by this technique. There were no hematomas. There was recurrence in eight ears (8 percent) in six patients. Two patients requested further surgery. No patients developed suture extrusion or granuloma. This is a simple and intrinsically safe procedure and does not cause irreparable complications such as anterior scarring or skin necrosis. The postauricular fascial flap seems to prevent suture extrusion. It may also help to reduce recurrence rates to acceptable levels.     

Improved technique for a one-stage repair of significant defects of the ear

An improved technique for repair of severe acquired partial defects of the auricle in one stage is described. The common postauricular flap with its base on the margin of the auricular defect is usually unable to repair a severe partial auricular defect in one stage because of the limited length of the flap. The authors developed this technique by means of lengthening the flap with a piece of subcutaneous tissue of the scalp, so that the ear framework can be covered completely in one stage. All flaps in this group survived totally. Seven patients with severe acquired partial defects of the auricle underwent this procedure, and good results were obtained.     

The tumbling concha-cartilage flap for correction of lop ear

This article presents a new surgical method that uses tumbling concha-cartilage flaps to correct lop ears. Through a posterior or anterior auricular skin incision, a rectangular or T-shaped cartilage flap is elevated from the concha and tumbled backward. After passing under the postauricular skin, the flap's tip is fixed to the lidded helix or scapha. The recoiling force of the flap's conchal side enables the lidded portion to be in a normal, erect, anatomic position. The method also increases the vertical height of the ear and creates a normally shaped scapha. Sixteen lop ears were corrected using this procedure, with most of them maintaining natural auricular features. Therefore, this method was considered effective for the correction of moderate lop ear deformity.     

A newly defined conchal floor arterial flap for auricular reconstruction

A conchal floor composite flap pedicled by skin of the helical crus has been well described in the literature. Here the flap is elevated based on the supply by an upper auricular branch of the superficial temporal artery. In this article, a newly defined conchal floor arterial flap is proposed. The flap is based on the main stem of the posterior auricular artery and its venae comitantes. Two types of conchal floor arterial flaps were elevated: a proximally based chondral arterial flap and a distally based chondrocutaneous arterial flap. The proximally based flap was used for earlobe reconstruction, whereas the distally based flap was useful in the reconstruction of the upper auricle. Nine congenital auricular malformations were successfully corrected with this newly defined conchal floor flap procedure. This type of flap is easier to elevate, more reliable, and more versatile than the one currently in use.     

The chondrocutaneous postauricular free flap

Use of the auriculomastoid region as a donor-site for a microvascular free flap is still not the general consensus. This report presents three patients with composite tissue defects of the face aesthetically reconstructed with a chondrocutaneous postauricular free flap. For its safe surgical application, additional anatomic knowledge was refined with cadaver study. Use of the chondrocutaneous postauricular free flap has some merits. Its dissection is straightforward and safer than when only the cutaneous unit is used. It also offers a more dependable vascularized composite tissue as a one-stage operation. With freedom of design, a variable combined facial defect can be delicately reconstructed. The final aesthetic results obtained were gratifying, and the donor-site deformity was minimal.     

Surgical techniques for a deep concha, a pseudomeatus, and high projection in congenital microtia

Some modified surgical techniques are described for constructing a deep conchal cavity and pseudomeatus and obtaining high auricular projection in congenital microtia. At the primary operation, a rather small portion of the microtic vestige is utilized for the lobule by switching, sparing the skin for the concha, with no free skin graft used. For higher projection of the auricle, three-dimensional transposition of a retroinfraauricular flap together with cartilage pieces underneath is applied to the cephaloauricular sulcus. A deep conchal cavity is constructed by further removal of the soft tissue there, transplantation of a cartilage for building a high posterior wall of the concha. The external meatus is successfully imitated by transplantation of a cone-shaped composite graft taken from the cymba of the opposite ear. The retroinfraauricular flap, the reconstruction of a deep concha, and the composite graft technique were successfully used in 55, 16, and 11 ears, respectively.     

A method for repair of cryptotia.

The key points in our method of repair of cryptotia are (1) to cover the skin defect on the posterior aspect of the ear after it is dissected from the head, and (2) to repair the cartilaginous deformity. We describe the use of a temporal skin flap for the former. For the latter, we make parallel incisions on the back of the superior crus and transfer a small graft of conchal cartilage there. The conchal cartilage graft "splints" the repaired crus against cicatricial contracture.     

Lid margin reconstruction with an orbicularis oculi musculocutaneous advancement flap and a conchal cartilage graft

A simple method to reconstruct the midlateral lid margin defect is described using an orbicularis oculi musculocutaneous advancement flap and a free conchal cartilage graft. This method is easy to perform not only in the lower eyelid, but also in the upper one, provides a natural gray line and a stable lid margin without postoperative eversion, and substitutes for the Leone and van Gemert procedure.     

Retroauricular island flap for eye socket reconstruction

This paper describes the use of a flap which is the random portion of an island flap based on superficial temporal vessels. The flap has three distinct anatomic portions: the cutaneous portion, which includes the postauricular skin, the triangular deepithelialized scalp and fascia above the ear, which augments random-pattern blood circulation to the cutaneous portion, and the superficial temporal fascia encompassing the vascular pedicle, which is dissected down to the upper pole of the parotid gland and unfolded using a cutback incision between the vascular pedicle and the second portion of the flap in order to increase the reach of the cutaneous portion. The flap has been successfully used in eight patients for reconstruction of missing or contracted eye sockets. In two patients, inconsequential superficial loss of the distal portion of the distal flap was observed. This flap can also be used for reconstruction of the external face, eyelid, and palate as well as soft-tissue augmentation.     

Oropharyngeal reconstruction using the supraclavicular artery island flap: a new flap alternative

Oropharyngeal reconstruction following head and neck oncologic resection has utilized local, regional, and free tissue transfer flap options. The modality utilized is often guided by the type of defect created as well as the surgeon's preference. In this article, the authors introduce the application of the supraclavicular artery island flap as a reconstructive modality following oropharyngeal oncologic ablation. Five patients underwent head and neck oncologic resection for oropharyngeal squamous cell carcinoma followed by single-stage reconstruction with an ipsilateral supraclavicular artery island flap. There were no flap failures and only one postoperative complication consisting of a postoperative oral-cutaneous fistula that resolved without surgical intervention. There were no donor-site complications. The supraclavicular artery island flap is a viable alternative for oropharyngeal reconstruction following head and neck oncologic resection. It is a regional flap that can be harvested without microsurgical expertise and yields reliable postoperative results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.     

Lower eyelid reconstruction with a cheek flap supported by fascia lata.

The use of a cheek rotation flap is a well-known method for reconstruction of a large defect of the lower eyelid. In this technique, a separate lining tissue supporting the cheek flap is required for full-thickness reconstruction. Previously, a chondromucosal graft or conchal cartilage has been used to support this flap. Recently, we have used a homologous or autologous fascia lata as support for the cheek flap instead of rigid tissues like cartilages. A fascia lata strip is fixed with tolerable tension to the medial canthal tendon and lateral orbital rim. The inner surface of the fascia and the cheek flap is lined with a buccal mucosa graft to decrease irritation of the conjunctiva and cornea. We present here seven patients in whom this procedure was used for lower eyelid reconstruction following resection of a malignant skin tumor. Based on follow-ups of 7 to 22 months, the functional and aesthetic results have been good in all cases. This procedure may be applicable for total or subtotal reconstruction of the lower eyelid.     

Frontalis musculocutaneous island flap for coverage of forehead defect

The use of the frontalis musculocutaneous flap as a pedicle island flap offers some advantages in frontal reconstruction. It can be used for immediate reconstruction following the ablation of a small or moderate area, even after harvesting of the frontal flap for nasal reconstruction. Because of its intact lateral bundle, it has the potential to carry some sensory innervation, albeit minimal, to the reconstructed area. We have found the frontalis musculocutaneous flap, when used as a pedicle island flap, to be an adaptable and dependable alternative flap for repairs after small or moderate resections in the frontal region. This flap could be performed immediately and in one stage, have a low morbidity rate, and allow a rapid aesthetic restoration; and, it is easy to perform. In two cases, we have observed some degree of venous congestion in the island during the early postoperative period but with success in final healing. The experience demonstrates that this flap should be considered as another valuable tool in reconstructive efforts directed at the forehead. We propose a novel method for the forehead reconstruction using the frontalis musculocutaneous island flap. A case is presented that demonstrates the use of this flap for repair in a depressed frontal defect.     

Aesthetic considerations of the medial gastrocnemius myocutaneous flap

A technique for the repair of a high anterior tibial defect is described in three clinical cases using a modified medial gastrocnemius myocutaneous island flap. The repair was done in such a way as to preserve as much of the normal contour as possible, after the fashion of the muscle flap alone, while retaining the advantages of full-thickness myocutaneous coverage of the defect. The result was an aesthetically improved reconstruction that we feel justifies further use of the gastrocnemius myocutaneous flap in selected patients.     

Innervated island flaps in morphofunctional vulvar reconstruction

In this article, the authors present their own experience in vulvar reconstruction following vulvectomy using two different innervated island flaps according to the size and site of the defect. Island-flap mobilization is possible thanks to the rich blood supply of the perineal region. The methods described are a "V-Y amplified sliding flap from the pubis" and a "fasciocutaneous island flap" raised from one or both gluteal folds. The V-Y amplified sliding flap from the pubis is indicated when the defect is symmetric and located anteriorly. This flap is harvested from the pubis and vascularized by the deep arterial network of the pubis. Sensory innervation is provided by branches of the ileo-inguinal nerve. The fasciocutaneous island flap, raised from one or both gluteal folds, can be used following hemivulvectomy or radical vulvectomy, respectively, to cover posteriorly located defects. Vascularization is provided by the musculocutaneous perforating branches of the pudendal artery, whereas sensory innervation is maintained through the perineal branches of the pudendal nerve. Twenty-two patients have undergone reconstructive surgery of the vulvar region from 1989 to date. On 14 patients, a V-Y amplified sliding flap was used; on 7 patients, reconstruction was carried out by island flaps raised from the gluteal fold. Both techniques are compatible with inguino-femoral lymphadenectomy, and they allow for a correct morphofunctional reconstruction and provide good local sensibility. The final result is aesthetically satisfactory, as all final scars are hidden in natural folds.     

Repair of pharyngocutaneous fistulas with the submental artery island flap

Pharyngocutaneous fistulas after total laryngectomy are difficult to manage and are a cause for significant morbidity to the patient. When fistulas fail to close with conservative measures, debridement and flap closure are indicated. Although a number of techniques to repair pharyngocutaneous fistulas are described, each of these procedures has its drawbacks. The authors have used the submental island flap to close postoperative pharyngocutaneous fistulas in nine male patients during the past 4 years. The mean patient age was 65 years (range, 57 to 75 years). The submental island flap is based on the submental artery, a branch of the facial artery. The inner aspect of the fistula was initially formed using hinge flaps on the skin around the fistula. Once a watertight closure of inner side was created, the skin defect was closed with the submental island flap. The maximum flap size was 6 x 3 cm and the minimum size was 4 x 2 cm (average, 4.8 x 2.7 cm) in this series. Direct closure was achieved at all donor sites. Patients were followed for 6 months to 4 years. No major complication was noted in the postoperative period. All patients have successfully recovered their swallowing function. The submental island flap is safe, rapid, and simple to elevate and leaves minimal donor-site morbidity. The authors believe that this technique is a good alternative in the reconstruction of pharyngocutaneous fistulas. Application of the technique and results are discussed.     

Inverted-U parascapular flap for the treatment of axillary burn scar contracture

In this paper we report the technique of using an inverted-U parascapular flap for treating axillary scar contracture. The advantages of using this inverted-U flap are that it is possible to close the donor site by primary suturing, it is possible to cover a large skin defect, and it is possible to construct either a cavity or a swelling in the skin-defect region.     

Our experience with combined procedures in aesthetic plastic surgery

The instep flap needs neither muscle nor a transposition base for survival or innervation. It can be transposed as an island fasciocutaneous flap either on the medial or lateral plantar neurovascular bundles or both, and it can be transferred also as a free flap from the opposite foot. Four cases demonstrating the use of the flap as an island and free flap are presented with follow-up ranging from 1 to 2 years. The absence of muscle in the flap provides greater stability of the heel reconstruction and results in a lesser secondary defect. Sensation in the flaps is diminished but adequate for long-term function, but hyperkeratotic reaction remains an unpredictable problem. The ability to transfer the flap as a free transfer widens the scope of the flap to reconstruct both heel and forefoot defects where local instep tissue or vascularity are inadequate for local reconstruction. The secondary defect, particularly when no muscle is included in the flap, has been minimal.     

Functional reconstruction of swallowing and articulation after total glossectomy without laryngectomy: money pouch-like reconstruction method using rectus abdominis myocutaneous flap

When a total glossectomy is performed without a laryngectomy, the functional recovery of swallowing and articulation is extremely important in maintaining the patient's quality of life. The authors established a money pouch-like reconstruction method in which a round and raised tongue is rebuilt using a rectus abdominis myocutaneous flap. In this method, the skin island of the rectus abdominis myocutaneous flap is created about 20 percent larger than the defect in both width and length. The skin island is sutured to the defect such that the excess skin folds into the shape of a money pouch. This allows the tongue to be reconstructed with its tip and dorsum touching the hard palate and its base bulging in the dorsal and posterior directions. Misswallowing was not detected in the three patients who had this surgery, and each of them had improved articulation sufficient to carry out daily conversations.     

A new arterial flap from the postauricular surface: its anatomic basis and clinical application

We studied the arterial pattern of the postauricular surface in 16 cadavers and compared them to the results of Doppler probing in the auricles of 15 human volunteers. The dissections revealed that the postauricular surface is mainly supplied by three to five sizable branches from the upper, middle, and lower divisions of the posterior auricular artery, traversing in a rather straight and cephalic direction toward the auricular rim. One or more branches of the middle division are constantly present and distribute over the upper two-thirds of the postauricular surface. These anatomic findings were compatible with the results of the Doppler probing. We have done four auricular reconstructions with postauricular arterial flaps with excellent postoperative results. It is worthwhile to use the postauricular arterial flap in restoring the middle third of the auricle.     

Isolated naso-ocular cleft: a one-stage repair

The naso-ocular cleft is a rare defect; however, isolated alar clefts with or without additional hamartomatous local tissue are an even rarer problem. The authors describe six unilateral and one bilateral cleft patients who were all initially repaired using the same operative procedure. The concept of this procedure is based on the principle that there is basically no soft-tissue deficiency but rather a malpositioning of the parts. The leading edge of the ala is re-created by a rotation advancement of both the medial and the lateral segments adjacent to the cleft. The created secondary defect is filled with a paranasal transposition flap. Three of our patients had hamartomatous excesses and were the most difficult to balance, and at the same time, two of these patients required subsequent bridging or augmentation using a free conchal cartilage graft. Examples of the operative procedures are outlined both schematically and clinically.
