Long-term outcome of autogenous rib graft nasal reconstruction.

Whereas reconstruction of the hypoplastic nose with rib grafting is common, the long-term outcomes of nasal growth and aesthetics are unknown. This study assessed nasal morphometrics, patient satisfaction, and the perception of nasal appearance by others up to 15 years after nasal reconstruction using cantilevered autogenous chondro-osseous rib grafting with rigid internal fixation in children. Records of all patients who received nasal rib grafts between 1983 and 1998 by one senior surgeon were reviewed. Patients in this study were operated on before their late teens and had greater than 1-year follow-up including serial photographic documentation. Nasal growth was determined by comparing anthropometric measurements preoperatively, perioperatively, and postoperatively. Patient satisfaction was determined through a questionnaire that addressed memory, donor-site morbidity, and nasal perception. Independent, blinded skilled observers who reviewed frontal and lateral photographs of the preoperative, perioperative, and postoperative intervals assessed nasal aesthetics. Thirty-two patients who underwent 38 rib graft reconstructions of the nasal dorsum and tip at an average age of 8.8 years constitute the study population. Six patients underwent secondary augmentation. The average interval between initial nasal reconstruction and evaluation for this study was 7.9 years. Comparative anthropometric measurements before and after surgery documented increases in both tip projection (2.3 percent) and nasal length (3.0 percent) and a decrease in nasolabial angle (1.9 percent). Patient satisfaction interview response rate was 100 percent of those whom we were able to contact (28 of 32). The average age at interview was 17.2 years. Most patients recalled the operation and denied recollection of pain. Donor-site long-term morbidity was not an issue for 86 percent of patients. Sixty-four percent of patients remembered their preoperative nasal appearance and 89 percent of these preferred the postoperative change and were not concerned with nasal scars or texture. Almost two-thirds of the patients had fixation screws removed from the nasal dorsum because of skin erosion, easy palpability, or visibility. Although several patients expressed a desire to make minor additional changes to their nose, only one of these elected offered presurgical consultation and none have had such surgery. The postoperative nasal appearance compared with that preoperatively was rated as improved for 66.3 percent of responses, 26.5 percent as unchanged, and 7.2 percent as deteriorated. Cantilevered autogenous chondro-osseous rib graft reconstruction of the nasal dorsum is an effective means of reconstruction for the hypoplastic nose in childhood with respect to morphometric measurements, patient self-perception, and the assessment of nasal appearance by others.     

Nasal reconstruction with full-thickness cranial bone grafts and rigid internal skeleton fixation through a coronal incision

The use of iliac and rib bone as onlay grafts to the nasal dorsum often fails because endochondral grafts resorb unpredictably. Membranous cranial bone grafts are less likely to resorb, especially when used with rigid internal fixation techniques. However, when split, they are often too thin and can be difficult to contour. Full-thickness cranial bone grafts were used to achieve nasal augmentation in 26 patients with end-stage nasal skeleton deficiency. All procedures were carried out using only a coronal incision. Grafts were harvested through a craniotomy, carved meticulously, and secured rigidly with miniplates or bicortical screws. Donor sites were reconstructed with split cranial grafts, leaving an intact cranial vault. No graft was lost to infection, and there was no significant donor-site morbidity. In carefully selected patients this method of full-thickness cranial bone graft reconstruction yields good results.     

Primary definitive nasal correction in patients presenting for late unilateral cleft lip repair

Almost 25 percent of unilateral cleft lip and palate patients present with their deformity in their teens or later years in the developing world. Because more than 80 percent of the world population lives in the developing world, the established protocol for repair of these deformities is not applicable to these patients. Despite the magnitude, there are no significant reports in the literature that deal with this problem. Several issues need to be addressed, but the author limits himself here to the correction of the nasal deformity. The patients at this age are very much concerned with the aesthetic outcome. Procedures described hitherto for primary nasal correction in infants are not successful in restoring nasal shape and symmetry at this late age of presentation. Our experience with radical correction of secondary nasal deformity in unilateral cleft lip patients presenting late prompted us to extend the concept by undertaking a definitive primary correction of the nasal deformity in cleft patients presenting late. Twenty-two patients with unilateral cleft lip deformity (nine male patients and 13 female patients) with ages ranging from 13 to 22 years, presenting between August of 1997 and December of 2000, are included in this study. Of these, 11 patients had a cleft of the lip alone, eight also had a cleft of the alveolus, and three had a cleft of the palate continuous with the cleft lip. All patients showed some maxillary hypoplasia. An external rhinoplasty with lip repair was carried out in all patients. The corrective procedures on the nose included columellar lengthening; augmentation along the pyriform margin, nasal floor, and alveolus using bone grafts; submucous resection of the nasal septum; repositioning of lower lateral cartilages; and augmentation of nasal dorsum by bone graft. Clinical follow-up ranged from 4 to 24 months, and the median follow-up period was 13 months. Results have been very good, and much better than results seen earlier with other primary rhinoplasty techniques. While repairing unilateral cleft lip in adolescents, the author thinks it would be most appropriate to address the entire gamut of the deformity in a single stage, provide complete vector reorientation, and augment the hypoplastic elements by autologous tissue. It is not just the fear of poor follow-up, but that merely correcting the lip deformity in these patients without attempting definitive rhinoplasty, in the author's opinion, would be insufficient surgical intervention.     

The role of septal surgery in management of the deviated nose

The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 260 patients seeking rhinoplasty to correct external nasal deviations; 75 percent of them had various degrees of nasal obstruction. Septal surgery was necessary in 232 patients (89 percent), not only to improve breathing but also to achieve a straight, symmetrical, external nose as well. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.     

Leave the fat, skip the bolster: thinking outside the box in lower third nasal reconstruction

Defects of the lower third of the nose often present especially challenging reconstructive dilemmas. The surrounding skin to match is often thick, sebaceous, and sun damaged, none of which characterizes the historically ideal periauricular donor skin for grafting. The surrounding nasal skin is quite stiff, precluding very small local flaps. To avoid the "misplaced patch" appearance of most classic full-thickness grafts to this area or the depressed scar of an elliptical excision, many surgeons turn to larger local or regional flaps. These provide not only skin color and texture match but also the necessary several millimeters of subcutaneous fat necessary for proper tip aesthetics. Many defects of the lower third are small, making many surgeons reluctant to employ these larger flaps with their long scars and potential to twist or distort delicate tip or ala anatomy. The author has sought a means to transport skin and subcutaneous fat for lower third nasal defects outside of flaps. On the basis of the superiority of nasolabial fold scars and a vast positive experience in the literature utilizing skin and fat composite grafts with no bolsters, the author applied these techniques to 33 lower third nasal defects in 29 patients. Of 33 grafts varying in size from 4 mm circular to 17 mm x 16 mm and retaining 1 to 5 mm of fat, no grafts were lost. Four grafts developed a 30 percent area or less of central necrosis resulting in localized depression. Three of these four grafts were in active smokers and the fourth graft was in a former smoker. Aside from these four grafts and one with considerable excess fat early in the series, contour was good to excellent. Hypopigmentation is still common but improves with time. Easily performed composite grafts effectively carry the necessary fat for aesthetic reconstruction and do not risk long scars on the nose and twisting of the tip and ala that can result from flaps. Revisions are infrequent and extremely simple when indicated.     

Use of cartilaginous autografts in nasal surgery: 8 years of experience

Although the cartilaginous autografts are one of the tissues more utilized in nasal surgery, a comparative study does not exist to determine which are better options and their precise indications. It is for this reason that a histopathologic analysis was carried out comparing the characteristics and properties of the four principal cartilages that are utilized in aesthetic functional surgery of the nose. Considering these particularities, the precise indications for the employment of the different cartilage as nasal autografts were determined. Of 1120 aesthetic functional rhinoplasties during a period of 8 years, 930 (83 percent) required cartilaginous autografts, 86 percent were primary, 11 percent were secondary, and 3 percent had two or more surgeries. Eighty-three percent of the grafts used were from nasal septum, 12 percent from the auricle, 3 percent from alar cartilages, and 2 percent from the rib. The anatomic sites in which they were employed consisted of the following: 64 percent between the medial crura, 28 percent as in Sheen's graft, 19 percent in the nasal dorsum, 8 percent as spreader grafts, 8 percent as in Peck's graft, and 3 percent in the rim to improve alar collapse. We followed at all times the previous indications for obtaining and placing the nasal autografts. Eighty-four percent of the patients were totally satisfied and only 8 percent required a second surgical procedure to achieve the results desired. Based on this study, it is recommended to utilize the cartilaginous autografts in nasal surgery considering three parameters: the physical and histologic characteristics of each cartilage, the anatomic site in which they are to be placed, and the effect desired with their application.     

Temporalis fascia grafts for facial and nasal contour augmentation

For the past 70 years, fascial grafts have been used in reconstructive surgery mainly because of their tensile strength. Although the thigh (fasciae latae) has been the principal donor site, fascia taken from the temporalis muscle has the advantages of (1) ease of harvest under local anesthesia, (2) usually being in the same operative field, (3) minimal postoperative discomfort, and (4) negligible residual scar deformity. These grafts can be effectively used as the sole source of contour augmentation of facial depressions in primary as well as secondary rhinoplasty. Such grafts undergo an initial uniform shrinkage (approximately 20 percent) during the first 4 to 6 weeks postoperatively due to compaction and condensation of the fibrous tissue of the fascia, after which the grafts stabilize and become firm. Concavities should be overcorrected accordingly. No inflammation or encapsulation has been seen clinically or histologically in 18 patients followed for periods ranging from 6 to 18 months.     

Nasal reconstruction using both cranial bone and ear cartilage

In this article, an anatomic reconstruction is described using cranial bone graft for the bony part of the nose while reconstructing the cartilaginous part with ear cartilage. This modification provides protection of the nose from the traumatic forces creating a flexible nasal tip. A modification is described and compared with the nasal reconstruction by calvarial bone itself.     

Effect of inspired air temperature on genioglossus activity during nose breathing in awake humans

Experimental data suggest the presence of sensory receptors specific to the nasopharynx that may reflexly influence respiratory activity. To investigate the effects of inspired air temperature on upper airway dilator muscle activity during nose breathing, we compared phasic genioglossus electromyograms (EMGgg) in eight normal awake adults breathing cold dry or warm humidified air through the nose. EMGgg was measured with peroral bipolar electrodes during successive trials of cold air (less than or equal to 15 degrees C) and warm air (greater than or equal to 34 degrees C) nasal breathing and quantified for each condition as percent activity at baseline (room temperature). In four of the subjects, the protocol was repeated after topical nasal anesthesia. For all eight subjects, mean EMGgg was greater during cold air breathing than during baseline (P less than 0.005) or warm air breathing (P less than 0.01); mean EMGgg during warm air breathing was not significantly changed from baseline. Nasal anesthesia significantly decreased the mean EMGgg response to cold air breathing. Nasal airway inspiratory resistance, measured by posterior rhinomanometry in six subjects under similar conditions, was no different for cold or warm air nose breathing [cold 1.4 +/- 0.7 vs. warm 1.4 +/- 1.1 (SD) cmH2O.l-1.s at 0.4 l/s flow]. These data suggest the presence of superficially located nasal cold receptors that may reflexly influence upper airway dilating muscle activity independently of pressure changes in awake normal humans.     

Augmentation rhinoplasty with dermal graft and review of the literature

Nasal augmentation required following a trauma or a rhinoplasty operation poses a challenging problem to many plastic surgeons. Currently, allografts and autologous tissues are used for nasal augmentation; however, an ideal technique has not yet been described. Although preferred for augmentation of different parts of the body, pure dermal graft use has not been described for nasal augmentation. The authors performed nasal augmentation using a dermal graft in 90 patients in their hospital between 1994 and 2000, and they followed up the patients for 6 months to 8 years. In this article, the early and late results of dermal grafts for nasal augmentation are presented, and their advantages and disadvantages are discussed with a review of the literature. It was concluded that the easily obtained dermal graft could be an appropriate alternative in nasal augmentation, though it has not been used widely for this purpose.     

Assessment of bilateral cleft lip nose deformity: a comparison of results as judged by cleft surgeons and laypersons

Reconstruction of bilateral cleft lip nose deformity is difficult and the outcome is inconsistent. This study was conducted to evaluate the gross outcome and the difference in the assessment of nasal appearance as judged by two groups of raters, cleft surgeons and laypersons. Sixty-four patients with bilateral cleft lip were selected for review. The patients' ages ranged from 5 to 30 years. All patients had undergone primary cleft lip repair and secondary nasal reconstruction, and had been followed for at least 6 months. One image for each patient, which included a digitized frontal, lateral, and worm's-eye view, was projected for evaluation by the raters. The raters included five cleft surgeons and five laypersons. A rating scheme was used in which a score of 3 was given for a good, close to normal nasal appearance, 2 for an average result that needed minor revision, and 1 for a poor result that needed major reconstruction. The scores were averaged for each patient in each group and for each group as a whole. The final outcome was judged as good, fair, or poor on the basis of the mean score for each patient. Statistical analysis was performed. The mean score for all patients was 2.08 as assessed by the laypersons and 2.18 as assessed by the cleft surgeon group. There was no statistically significant difference between the two groups. Comparisons on rating scores among different raters revealed a fair agreement on the ratings within each of the two groups. The results were found to be good in 29.7 percent, fair in 64.1 percent, and poor in 6.3 percent of patients when evaluated by the surgeons. When rated by the laypersons, the nasal appearance was found to be good in 26.6 percent, fair in 60.9 percent, and poor in 12.5 percent of patients. This difference in distribution between the two groups was not statistically significant. When comparing the results given by the two groups of assessors, there was agreement on the nasal appearance in 65.6 percent of patients, and a difference in grading in the rest. For the patients who received different grading, the surgeons rated them one grade higher in 63.6 percent and one grade lower in 36.4 percent. There was no difference in grading between any of the evaluators that reflected a two-grade discrepancy in evaluation of results. This study shows that the surgical outcome of bilateral cleft lip nose deformity repair, at the authors' institution, is less than optimal. When assessing bilateral cleft lip nose appearance, the judgment of results by cleft surgeons was similar to that of the laypersons. However, different rating of results existed within each of the two groups, supporting the importance of clearly assessing patient/parent expectations and defining realistic surgical goals.     

Free split-cutaneous perforator flaps procured using a three-dimensional harvest technique for the reconstruction of postburn contracture defects

With recent advances in free-tissue transfer, microsurgical techniques have been used more frequently for the reconstruction of postburn contracture defects. Traditional methods, including full-thickness skin grafts and local flaps, often result in a good outcome; however, multiple operative procedures, long periods of splinting, and physical rehabilitation are often required. Free split-cutaneous perforator flaps, consisting of one large cutaneous paddle with two perforating vessels split into two separate skin regions, were used for two kinds of postburn contractures: rectangular and spatially separate defects. From September of 2000 to October of 2002, seven patients underwent this method of reconstruction at Chang Gung Memorial Hospital in Taiwan. A three-dimensional flap harvest method, in which the skin paddle is circumferentially elevated early in the harvest, was used. Postburn scar contractures had resulted from flame burns in six cases and an electric burn in one case. The reconstructive regions included the neck in two patients, the breast in one patient, and the hand in four patients. There were six male patients and one female patient, with a mean age of 34.8 years (range, 25 to 49 years). The size of the excised scar ranged from 120 cm2 to 308 cm2 (mean, 162.3 cm2). The size of the unsplit flaps ranged from 144 cm2 to 337.5 cm2 (mean, 192.1 cm2). The average time for flap harvest using this three-dimensional harvest technique was 39.1 minutes. The average total operative time was 4.3 hours. The average total hospital stay was 7.3 days (range, 6 to 11 days). All flaps survived without major complications. The donor site was closed primarily in all cases. At a mean follow-up time of 9 months, the functional and aesthetic outcomes showed significant improvement as compared with the preoperative condition. In this study, a new method of flap harvest using a three-dimensional technique is introduced, and its application in the reconstruction of postburn contractures is evaluated.     

Nasal augmentation with Surgicel-wrapped diced cartilage: a review of 67 consecutive cases

Cartilage grafting has been used extensively to correct both the functional and aesthetic aspects of the nasal framework. The technique described by Erol ( 105: 2229, 2000) uses Surgicel-wrapped diced cartilage grafts in rhinoplasties. The advantages include its ease of preparation, the large volume of graft substrate available for use, and the avoidance of contour irregularities in the areas of placement. A retrospective case review of 67 consecutive patients who were treated with a Surgicel-wrapped diced cartilage graft as part of an aesthetic and/or functional rhinoplasty, in a 5-year period between 1995 and 2000, was performed in this study. All cases of congenital nasal deformities or deformities caused by trauma or tumors in which the technique was used were excluded. The charts were reviewed to determine demographic variables, the surgical procedures performed, prior operations, the rhinoplasty approach used, and the graft donor and recipient sites. Preoperative and postoperative photographs were examined, and the results were assessed. Data on the donor and recipient sites, complications, and the necessity for revisionary procedures were tabulated. There were two complications, namely, an infection, which resolved with aspiration and oral antibiotic therapy, and a recurrence of a dorsal depression, which necessitated repeated augmentation within 6 months. The technique of using Surgicel-wrapped diced cartilage proved to be effective for the augmentation of various areas of the nose. The complication and revision rates were acceptable and comparable to those of other techniques. Patient satisfaction with the aesthetic results was rated highly, with no reports of graft extrusion or contour irregularities. This technique is recommended for nasal augmentation and contouring for selected rhinoplasty patients.     

Surgical correction of the nose and midface in maxillonasal dysplasia (Binder's syndrome)

In 48 patients with maxillonasal dysplasia the retruded nasal base was corrected with onlay cancellous bone grafts after subperiosteal dissection using an oral vestibular approach. Support for the nasal dorsum was achieved in 39 patients with an L-shaped bone graft from the iliac crest introduced through the same approach. The advancement of the nose was found stable on lateral cephalograms; i.e., resorption did not occur. However, the grafts showed considerable remodeling. Half the patients found the stiffness of the nose to be disturbing. In nine patients, the cartilaginous septum was used instead as a support for the nasal dorsum and tip. At operation, the entire cartilaginous septum was mobilized after subperichondrial dissection and rotated forward either pedicled at the nasal dorsum or completely released. Cartilage regenerated in the periochondrial pocket left behind the advanced septum. The anterior transfer of the nose was 6 to 10 mm. The use of septal advancement is preferred over bone implants in the correction of maxillonasal dysplasia in patients in whom the bony nasal dorsum is of adequate height because it results in a soft and flexible nose and the risk of traumatic fracture and resorption is eliminated. The technique has been used in adolescents with promising results.     

Distant effects of dorsal and tip grafting in rhinoplasty.

Grafts to the nasal dorsum and tip, whose local effects are well known, also have distant effects that may not be as readily obvious but that nevertheless are just as real. Dorsal and tip grafts can shorten or lengthen the nose (relatively and absolutely), affect nasal symmetry, preserve or alter nasal ethnic characteristics, and alter dorsum/tip relationships. Each of these properties increases the utility of cartilage and bone grafts in treating a variety of nasal configurations.     

Management of congenital bilateral cleft nose

A rare case of nasal clefting was presented to illustrate and emphasize the following points: The workup of nasal clefting should be complete to rule out associated deformities. Marked improvement may be noted with normal growth during the first few years of life. The surgical procedure employed a primary V-Y flap harvested from the central excess of nasal skin based on a very thin vascular area at the nasal columella. At this primary procedure, the flap was telescoped on itself to provide fullness in the nasal tip area. It was also split, and two transposition flaps were inset into the gap left behind by rotating the ala into normal position. The donor area of the V-Y flap provided easy access to the intercanthal area so that the excess skin on the bridge of the nose could be reduced. Two subsequent minor procedures were required for adjusting irregularities in the tip.     

Nasal reconstruction: seeking a fourth dimension

A method of nasal reconstruction emphasizing the use of thin but highly vascular local lining and cover flaps to allow successful primary placement of delicate cartilage grafts is presented. The cartilage fabrication provides projection in space, airway patency, and, when visible through conforming skin cover, the delicate contour of the normal nose. Because tissue is replaced in kind and quantity, the need for multiple revisions to sculpt and debulk is decreased. Techniques and four case reports describe its applications to tip, heminose, subtotal, and total nasal defects.

Augmentation rhinoplasty: observations on 1200 cases

Over the past 14 years, from January of 1975 to December of 1988, we have done 1263 aesthetic rhinoplasties using ear cartilage. In the field of augmentation rhinoplasty, many kinds of materials, such as bone, septal cartilage, ear cartilage, and prostheses, were used. In this paper, we limit discussion to our experience with the technique for the augmentation of the nasal dorsum using the ear cartilage and compare this with other materials. Patient ages ranged from 15 to 72 years, with an average of 24 years. Some 95 percent of patients (1199) were female, and only 5 percent (64) were male. Patients were followed for a minimum of 6 months and a maximum of 20 months, with average follow-up only 8 months. Of course, we know that this is a very short follow-up period, but we could not follow patients longer because if they had no complaint about the results at the 6-month visit, they never returned, despite our efforts. Five-hundred and ten of the 1263 patients (40 percent) had been augmented elsewhere, and the silicone prosthesis was already in place. However, 753 patients (60 percent) had no previous operation. For the 510 patients (secondary rhinoplasty patients), too-high or too-large a prosthesis was the largest complaint in number, totaling 378 cases (74 percent), and psychological dissatisfaction, such as pain or an uncomfortable sensation, was the second largest in number, totaling 104 cases (20 percent). For the 753 patients (primary rhinoplasty patients), the main complaint was too-short or too-flat a nose (100 percent).(ABSTRACT TRUNCATED AT 250 WORDS)     

Growth potential in onlay bone grafts: a comparison of vascularized and free calvarial bone and suture bone grafts

Vascularized bone grafts are characterized by a viable cell population with osteogenic potential. These features suggest that continued growth can be anticipated following vascularized membranous bone transfer in a growing craniofacial skeleton. The present paper compares the potential for appositional bone growth in vascularized and free calvarial onlay bone grafts. In seven 8-week-old beagles, growth was assessed by direct caliper measurements of graft dimensions intraoperatively and 16 weeks postoperatively. Vascularized grafts demonstrated a 50 to 60 percent increase in size in all dimensions compared to 10 to 20 percent growth in free grafts (p less than 0.01). Microradiography revealed preservation of calvarial bony architecture and minimal resorption in vascularized grafts, while triple-fluorochrome labeling confirmed subperiosteal appositional bone formation. Free grafts were characterized by significant resorption and a delay in subperiosteal bone formation.
