Irradiated homologous costal cartilage: versatile grafting material for rhinoplasty.

For most surgeons, nasal septal cartilage is the first choice in septoplasty. However, when this source is depleted, an alloplastic implant material might be preferable over other autogenous donor sites in order to avoid additional scars, morbidity, and lengthened operating time. In the alloplastic spectrum, irradiated costal cartilage (ICC) has certain advantages. Herein, we present our results with ICC in a wide range of septorhinoplasties to show its versatility and reliability. Sixty-five patients were included in the study. There were 42 male and 23 female patients. According to the indications, there were four groups of patients: (I) secondary septorhinoplasty (n = 24), (II) traumatic deformity (n = 21), (III) primary septorhinoplasty (n = 13), (IV) deformity due to previous septal surgery (n = 7). The mean follow-up period was 33 months. No significant resorption was detected in any of the patients. Minor complications developed in four cases (6%), including deformity in the dorsal graft, excessive graft length, and erythematous nasal tips. Aesthetic and functional results were satisfactory in the remaining cases. The low incidence of major complications and the versatility of ICC make it a safe and reliable source of cartilage graft for both primary and secondary septorhinoplasties when autogenous septal cartilage is either insufficient or unsuitable.
