Choanal atresia is a rare disease usually of congenital origin. The authors encountered a case with bilateral choanal atresia of acquired origin and report on surgery by transpalatal approach and also on postoperative local treatment with injection of steroid. Local injection with Rinderon produced a favorable result in suppression of granulation tissue which developed 30 days postoperatively, but failed to control cicatrization of tissues after operation.
The complete nasal obstruction, anosmia and persistent mouth breathing which were suddenly relieved after operation, as observed in this patient, presented evidence on which basis an interesting discussion could be made on the physiology of olfactory sense. The authors discussed the relation between hematogenous olfaction and accessory olfactory system and suggested that disuse atrophy of the olfactory cells seldomly occurs at least within 6 months.
