Donor site morbidities resulting from conchal cartilage harvesting in rhinoplasty.

[OBJECTIVE] Conchal cartilage is frequently used in rhinoplasty, but donor site morbidity data are seldom reported. This study aimed to investigate the complications of conchal cartilage harvesting in rhinoplasty.

[METHODS] A retrospective chart review of 372 patients who underwent conchal cartilage harvesting for rhinoplasty was conducted. Data regarding patient demographics, types of nasal deformities, graft usage and complications were analysed.

[RESULTS] A total of 372 patients who underwent conchal cartilage harvesting for rhinoplasty were enrolled. The harvested conchal cartilage tissues were used in a variety of applications: tip graft, dorsal graft, septal reinforcement and correction of nostril asymmetry. Nine cases (2.4 per cent) with donor site morbidities were identified, including four cases (1.1 per cent) with keloids and five cases (1.3 per cent) with haematomas.

[CONCLUSION] Conchal cartilage harvesting is a safe and useful technique for rhinoplasty, with a low complication rate. However, patients should be informed about the possibility of donor site morbidities such as keloids and haematomas.
