Analysis of National Outcomes for Simple Versus Complex Nasal Dermoid Cyst Excision

Nasal dermoid cysts represent a spectrum of complexity from dermal sacs to multiloculated sinus tracts with intracranial extension with treatments ranging from outpatient excision to transcranial procedures involving dissection of the dermoid from the dura mater. In this study, the authors examined national outcomes across the spectrum utilizing the NSQIP database. Interestingly, complication rates were uniformly low at 1.2% even though those requiring transcranial excision required significantly longer surgical procedures (P = 0.001), and were significantly more likely to be admitted as inpatients (P < 0.001). Risk factors for longer surgery included patients with comorbidities (P = 0.006), patients requiring rhinoplasty (P = 0.001), and patients requiring a craniotomy (P = 0.023). While uncommon (0.3%), infectious complications remain primary drivers of postoperative morbidity. The NSQIP database does not allow for calculation of recurrence risk, likely a driver of poorer long-term outcomes, and efforts to quantify recurrence risk will be the subject of future research.
