Introduction
Nasal dermoid sinus cysts (NDSCs) are the most common lesions associated with midline craniofacial anomalies, in the majority of cases diagnosed during childhood. NDSCs affecting the frontal sinus are rare.
Aim
To demonstrate the clinical, radiological and diagnostic pitfalls of NDSCs affecting the frontal sinus.
Material and methods
A retrospective analysis of NDSCs affecting the frontal sinus with a literature review and a novel classification is presented.
Results
We present a rare and complex case of an NDSC in an adult patient that affected the frontal sinus. Endoscopic-assisted open rhinoplasty with endoscopic sinus surgery – Draf type 2B approach – was performed as an effective removal method of choice. A literature review supports our report.
Conclusions
NDSCs affecting the frontal sinus can mimic complications of sinusitis. A minimally invasive combined technique of endoscopic-assisted open rhinoplasty with endoscopic sinus surgery – Draf type 2B frontal sinus approach – is recommended for treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
