The nasal dermoid is a rare congenital midline lesion with a yearly incidence of approximately 1:20.000-40.000 births. The treatment of a nasal dermoid is always surgical. Literature describes various methods of incision and resection, depending on the location and extension of the lesion. For example, when located superficially in the skin-soft-tissue envelope of the nose, a simple transcutaneous resection can suffice, but a dermoid that extends into the deeper midline structures of the nose and anterior cranial fossa is more challenging. The primary aim of this retrospective descriptive study is to review the diagnostic and surgical steps that were undertaken during the treatment of nasal dermoid cysts in the Erasmus Medical Center from 2000 until 2018. We focussed on the outcome of different surgical approaches by looking at rates of recurrence and postoperative scarring. The second aim of this study was to combine our data with literature findings, in order to define an up-to-date diagnostic and surgical flow-chart to manage the nasal dermoid involving different nasal subsites and extra nasal extensions.
