Congenital hypoplasia and aplasia of different segments of medial crus: A case report.

[INTRODUCTION] Congenital anomalies of lower lateral cartilages are very rare. Difficulties to detect before the operation may cause problems during the surgery. In this paper, we presented a unique deformity with the combination of aplastic and hypoplastic segments of lower lateral cartilage.

[METHODS] A 21-year-old female patient who underwent rhinoplasty were enrolled in this study. Airway impairment, prominent nasal hump, droopy nasal tip and nostril asymmetries were observed in physical examination.

[RESULTS] Partial aplasia and hypoplasia on the right-sided lobular segment and hypoplasia on the left-sided lobular segment of the middle crus were detected. Hypoplasia of the columellar segment and footplate segment of the medial crus was observed on both sides. Also, intercrural soft tissue volume was low. Defective medial crus was reconstructed with the septal cartilage graft.

[CONCLUSION] Although a rare occurrence, awareness of congenital lower cartilage anomalies is important for surgical planning and reconstruction of deformities. Cartilage tissue reflection to the skin surface and examination of each tip segment is crucial to detect anomalies preoperatively.
