Supernumerary Nostril: Formation of a Large Additional Nasal Cavity in an Adult Patient.

The supernumerary nostril is one of the rarest congenital nasal deformities. Most of the reported cases published were in young patients, and surgery was performed according to the surgeon's preference. The authors report a case of supernumerary nostril in an adult with a large additional nasal cavity and describe an effective surgical method. The operation was performed with the following steps: alar base and open rhinoplasty incisions were performed to widen the surgical field of view. An incision was made around the additional nostril in the nasal vestibule. The tract of the additional nostril was circumferentially excised, and the raw areas were approximated. The remnant portion was completely removed to combine the two nasal cavities into one. Weir excision, augmentation rhinoplasty, and tip-plasty were performed. The authors were able to obtain satisfactory aesthetic and functional effects by performing separate surgical methods for a supernumerary nostril with large additional nasal cavities in an adult.
