Congenital Anterior Nostril Atresia in Old Age: A Case Report and Literature Review.

Atresia of the anterior nares is usually caused by acquired disorders such as iatrogenic damage, burns, and postoperative scar, but congenital cases are relatively rare. Here, we report a rare case of congenital anterior nostril atresia in an aged person with bilateral nasal congestion and snoring. The patient underwent surgery, and no recurrence was observed after a 2-year follow-up. To increase our understanding on this condition, we performed a literature review and discussed its associated clinical features, differential diagnoses, and treatment methods.
