Presentation and management of nasal dermal sinus: a case series

Background and aims: Nasal dermal Sinus is a relatively rare congenital condition. We have reviewed our experience in the presentation and management of these cases. Material and methods: This is a retrospective study from June 2006 to January 2019. Patients presented with a nasal pit, with or without a hair in it, were selected. They were studied for their various aspects before and after the operation. Results: Out of eight patients of our series, one presented with infection, and hence operation was done later. One patient’s parents refused this operation at one sitting with his other condition, and therefore seven patients were operated on. Complete excision of dermal sinus by midline vertical incision under general anaesthesia was done. One patient had a recurrence and was reoperated 14 years later. Follow-up was from 1 to 13 years, with a mean of 6 years. Conclusion: Nasal dermal Sinus and dermal cyst without fistulae are two different entities. Most of the sinuses of this condition do not bear the intracranial extension. Excision can be done from the nose, and cranial exploration is rarely required.
