Benefits of medially based perichondrio-adipo-dermal flap in cartilage sparing prominent ear surgery.

[BACKGROUND] Cartilage-cutting and cartilage-sparing techniques are the two types of otoplasty procedures. Because of the significant risk of haematoma, skin necrosis, and ear deformity, cartilage-cutting techniques have been questioned. As a result; suture-based cartilage-sparing procedures such as Mustarde and Furnas suture procedures have grown in popularity. However, these techniques have a tendency for deformity recurrence due to cartilage memory and suture fatigue, as well as the possibility of suture extrusion and pinpricking sensation of the sutures.

[METHODS] In this study, we used a medially based adipo-dermal flap including perichondrium which is elevated from the back of the auricle to cover and support a cartilage-sparing otoplasty, thirty-four patients (14 female and 20 male) were operated using this technique. The medially based perichondrio-adipo-dermal flap is advanced anteriorly and fixed to the helical rim under cover of the distal skin flap. This procedure sought to cover the suture line preventing suture extrusion and support in the repair of the deformity preventing its recurrence.

[RESULTS] The average operative time was 80min, ranging from 65 to 110min. The patients passed the early postoperative period uneventfully except for 2 patients; one patient (2.9%) developed haematoma, and the other patient developed a small area of necrosis on the new antihelical fold. In late the postoperative period recurrence of the deformity developed in one patient. No patients developed suture extrusion or granuloma.

[CONCLUSION] The treatment to repair prominent ears is easy and safe, with benefits such as a natural-looking antihelical fold and minimal tissue stress. The medially or proximally based adipo-dermal flap may help to lower recurrence rates and suture extrusion.
