Nasal Tip Dermoid Sinus Cyst Excision by Open Rhinoplasty Technique

Nasal dermoid sinus cysts (NDSCs) are uncommon midline developmental anomalies with an estimated incidence of 1:20,000 to 1:40,000 births.1,2 NDSCs are distinct from dermoids in other regions; they may have an intracranial extension, requiring careful interventional strategies. These lesions can be present anywhere in midline, as sinus or cyst, from glabella to columella, with glabella being the most common site. Intermittent secretion of cheesy offensive material on manipulation and recurrent infections are frequently observed. Hairy outgrowth from the sinus opening, if present, is pathognomonic, but is found in less than half of the patients.1,3 Preoperative radiological investigation with CT (computed tomography) and MRI (magnetic resonance imaging) scans is mandatory to rule out intracranial extension. All in all, complete excision of the cyst along with its tract is the only definitive therapeutic modality. In this study,we report a case ofNDSC in a 3-year-oldmale childwho underwent excision byopen rhinoplasty approach.
