Dermoid sinus is the most common midline nasal anomaly. Intracranial extension has been reported in up to 45% of cases and requires a combined intracranial-extracranial besection. We present a technique of en-bloc ostectomy of the central bandeau and nasal bones to approach this malformation. This allows unobstructed visualization of the entire cyst and sinus tract, including portions that traverse or lie under the nasal bones, and ensures complete excision. Additionally unnecessary disruption of the nasal bones and facial scarring are avoided.
皮样窦是最常见的中线鼻部畸形。据报道，高达45%的病例存在颅内延伸，需要进行颅内-颅外联合切除。我们介绍一种整块切除中央带和鼻骨的技术来处理这种畸形。这使得能够无阻碍地观察整个囊肿和窦道，包括穿过鼻骨或位于鼻骨下方的部分，并确保完整切除。此外，还避免了鼻骨的不必要破坏和面部瘢痕形成。
