Supernumerary Nostril with Ipsilateral Maxillary Sinus Hypoplasia: Surgical Reconstruction in an Adolescent

Supernumerary nostril, otherwise known as triple nostril or accessory nostril, is a rare congenital deformity resulting from aberrant embryological development. It is often found associated with other deformities of face such as cleft lip, microcornea and congenital cataract. In the following case report, we describe the case of a 14-year-old boy presenting with a unilateral supernumerary nostril in conjunction with congenital underdevelopment of right maxillary sinus. CT scan showed a deformed right nasal cavity with non-visualization of nasal turbinates and meati and an undeveloped right maxillary sinus. Following reconstructive surgery, the supernumerary nostril was merged with the right nostril to give rise to a single right nasal cavity. A second-stage surgery on the lines of rhinoplasty is planned to further improve the shape of the nose.
