OBJECTIVESurgery is the curative treatment for nasal dermoid cysts. Many different surgical incisions have been advocated. All approaches described have the advantage of either improved accessibility or improved patients'cosmetic satisfaction, but none is optimal. We designed a new transseptal endoscopic approach for the treatment of nasal dermoid sinus cyst and reported the result of a special case.

METHODSThe diagnostic studies, the operative technique, and the result of 18 month follow-up were presented.

RESULTSThe patient, a 16 years old girl, remains free of disease 18 months after surgical treatment, most importantly without facial scar.

CONCLUSIONSTransseptal endoscopic approach is an alternative surgical technique for selected nasal dermoid cysts. So far as we know, the operative method presented in the current report is the first surgical approach reported in the world literature.
