Abstract

Objectives: Concha cartilage is recommended for correction of cleft nasal deformities. Morbidities at the donor site have been reported in esthetic rhinoplasty cases. Reports on cleft patients are limited, so we investigated the complications of concha cartilage harvesting using the retroauricular approach in cleft rhinoplasty and their management. Materials and Methods: This was a retrospective review of the charts of 63 patients with cleft deformities who underwent septorhinoplasty with concha cartilage. All cases were harvested using a retroauricular approach. Data on patient demographics, surgery type, amount of cartilage harvested, and complications were gathered. Results: Sixty-three patients were enrolled (21 males and 42 females). The mean age of patients was 20.2±5.9 years. Complications were observed in 6 cases (9.5%) and included delayed wound healing (4.8%), prolonged postoperative pain (1.6%), postoperative paresthesia (1.6%), and prominauris (1.6%). Conclusion: The rate of complications associated with concha cartilage harvesting using a retroauricular approach is low. The use of meticulous surgical techniques, especially hemostasis control and adequate wound dressing, is key to minimizing postoperative complications.
