Nasal dermoid sinus cysts are the most common congenital midline nasal lesions. The frequency of intracranial extensions varies from 5% to 45%. Complete surgical excision of nasal dermoid cyst and any associated sinus tract is essential for cure and any residual ectodermal elements result in a high rate of recurrence and complicated infections. Many different approaches have been described for the removal of nasal dermoids in the past two decades, ranging from a simple extracranial excision to complex procedures in which a combined extracranial-intracranial approach is required. We hereby report two cases of nasal dermoid sinus cysts in children with intracranial extension which were managed with an endonasal endoscopic procedure. We describe the technique we implemented for this procedure and for the reconstruction of the skull base defect.
鼻皮样窦囊肿是最常见的先天性中线鼻部病变。其颅内延伸的发生率在5%至45%之间。彻底手术切除鼻皮样囊肿及任何相关的窦道对于治愈至关重要，任何残留的外胚层成分都会导致高复发率和复杂感染。在过去二十年中，已经描述了许多不同的方法来切除鼻皮样囊肿，从简单的颅外切除到需要联合颅外-颅内入路的复杂手术。我们在此报告两例儿童鼻皮样窦囊肿伴颅内延伸，采用鼻内镜手术进行治疗。我们描述了为此手术及重建颅底缺损所实施的技术。
