The Cartilage-Sparing Versus the Cartilage-Cutting Technique: A Retrospective Quality Control Comparison of the Francesconi and Converse Otoplasties

From a total of 281 patients with protruding ears who underwent a bilateral otoplasty between 1990 and 2001, a group of 28 (10%) was selected for a retrospective quality control study. The goal was to compare two methods of otoplasty, the Francesconi, a cartilage-sparing technique, and the Converse, a cartilage-cutting technique, in terms of objectively measurable and subjectively discernable differences in results. Objective parameters included measurement of the three cephaloauricular distances and the conchoscapal angle. An independent plastic surgeon performed the evaluation by means of a systematic evaluation system for rating cosmetic surgical procedures and a 5-point visual analog scale for rating satisfaction. The patients subjective rate of satisfaction also was investigated using the 5-point scale. The mean medial and inferior cephaloauricular distances were significantly smaller in the Francesconi group. The concoscaphal angle was 90°, or less in all the patients of the Francesconi group, but more than 90° in eight patients (57%) of the Converse group (p = 0.041). Accordingly, the independent surgeon found adequate correction of protrusion in 86% of the Francesconi group and 50% of the Converse group (p = 0.050). His satisfaction rate was significantly in favor of the Francesconi technique (p = 0.006). Not unexpectedly, the patients satisfaction rate was comparably high in both groups, and there was no statistical difference between them. In conclusion, the quality control led to a clear preference of the Francesconi over the Converse otoplasty. In addition, the assessment of the postoperative results with the systematic evaluation system offered an excellent information base by which to judge the results of otoplasty. Consequent use of this evaluation system will lead to progress in the surgical procedure.     

Otoplasty: an analysis of technique over a 33-year period

OBJECTIVE: To compare the merits of otoplasty technique with a diverse patient population as experienced spanning a period greater 30 years. STUDY DESIGN: A review of a series of otoplasty cases that occurred in two distinctly different clinical settings during a 33-year period. METHODS: A retrospective analysis of 211 patients undergoing otoplasty from 1969 to 1982 in a military hospital setting was compared with 118 patients receiving otoplasty from 1982 to 2002 in a university/private practice setting. The patient population consisted of 180 adults and 149 children. RESULTS: Otoplasty patients in the military setting were primarily adults, whereas those in the university/private practice setting were primarily children. In the adult population, 98.9% of patients required use of lateral conchal cartilage resection combined with a mattress suture technique. In the pediatric population, all patients required use of a mattress suture technique and in 83.2% of selected cases limited lateral conchal cartilage resection was required. CONCLUSION: Otoplasty technique involving lateral conchal cartilage resection, mattress suture fixation, or a combination of both is applicable to diverse patient populations.     

Otoplasty for lop ears

The classification of malformations of the auricle is reviewed. Hinderer's technique is described. It is based on long oblique skin and cartilage flaps of the upper pole of the ear, taken in opposite directions for expansion of the helical arch, thus preventing a later visible notching at the helical rim. The remaining scapha is straightened and the superior crus and antihelical fold are formed by scratching and sandpaper abrasion of the lateral surface. A deep concha is treated by a cartilage strip expansion from the posterior conchal wall.     

Posterior Auricular Muscle Flap as an Adjunct To Otoplasty

Prominent ear deformity is a common congenital ear deformity. Prominent ear deformity includes components such as valgus of concha, failure of scaphal folding, conchal hypertrophy, and prominent lobule. The deformity and the elastic properties of the ear cartilage determine the method of surgical correction in each case. Concha-mastoid suture, conchal excision, and posterior auricular muscle excision are different treatment options for mild to severe cases of conchal hypertrophy and valgus deformity. In this article we present a method of conchal excision, combined with a posterior auricular muscle flap, to repair severe conchal hypertrophy or valgus deformity. Six patients (11 ears) were operated on using this method. The results obtained were satisfactory. Postoperative results at 6 months were satisfactory in all patients. The smoothness and the natural appearance of the conchal bowls were notable in all patients. In contrast to the early methods of utilizing the posterior auricular muscle by transposing to the scapha or excising, its usage as a muscle flap for conchal hypertrophy and valgus deformity may be a promising option for the future.     

The treatment of prominent ears: A 25-year survey of the island technique

The authors report on a 25-year retrospective study of 488 cases of prominent (protruding) ears corrected by the island technique of Pitanguy.     

An improved draping method for otoplastic surgery

An alternative method of draping of the ears is presented in which a mesh gauze dressing is used as an adjunctive method for restraining hair from the surgical field. It use is rapid and permits exposure and visibility of the ears bilaterally.     

Pinna synthetic mold for otoplasty techniques application

Introduction

The ear deformity Tanzer type V, also known as prominent ears, is the most common genetic defect of the pinna. The surgery designed for its correction is known as otoplasty. This esthetic surgery can be performed using different techniques, which requires great skill of its operator.
