Abstract
Supernumerary nostril is an extremely rare congenital nasal disorder, with additional nostrils of unknown etiology. The choice of supernumerary nostril reconstruction technique is adjusted to the patient's clinical manifestations. This study evaluated a case of 12-year-old male patient with an additional nostril on the right side of the normal nostril since birth. The patient was diagnosed with a functional supernumerary nostril and treated with nasal reconstruction. Functional supernumerary nostril reconstruction is considered to be functional, cosmetic, and psychosocial development. Internal approach reconstruction was performed using an endoscope to maintain the functional part of the nose, and an external approach reconstruction was performed to form a near-normal nasal morphology. Rhinoplasty outcome evaluation (ROE) can be used to evaluate the patient's psychosocial status after reconstruction procedures.
