Mucocoele of the paranasal sinuses falls within the scope of interest for neurosurgery when erosion of the sinus wall and the osseous structures of the skull base develops and the lesion extends towards the cranial cavity, the orbit, the cavernous sinus or the sella turcica. The pa-per aims to present the method of treatment of extensive mucocoele which is used in our clinic.
We treated 7 patients (2 women and 5 men; age range: 27-68 years). Mucopyocoele was diagnosed in two cases, and mucocoele in the other five. In 5 cases, extension of the mucocoele to the cranial cavity and the orbit or to the ethmoid sinus and the orbit was observed. In the remaining 2 cases, mucopyocoele extended to the ethmoid sinus, the sphenoid and maxillary sinuses, cranial cavity and the orbit. The purpose of surgery was to remove the mucocoele or the mucopyocoele and to prevent recurrence.
The postoperative course in all 7 patients was uneventful. All symptoms gradually receded. No relapse was observed in any patient during a follow-up period that varied from 10 months to 8 years; nor did incidents of inflammation of collateral sinuses occur.
The treatment of mucocoele or mucopyocoele of the frontal sinus penetrating to the cranial cavity and the orbit consists of the following stages: cranialization of the frontal sinus, complete resection of the mucosa, tight closing of the frontal-nasal duct, and separating the air space of the opened collateral nasal sinuses from the cranial cavity with a large pedicled periosteal flap.
当鼻窦黏膜囊肿侵蚀鼻窦壁和颅底骨结构，并向颅腔、眼眶、海绵窦或蝶鞍扩展时，属于神经外科的治疗范畴。本文旨在介绍我们科室治疗广泛鼻窦黏膜囊肿的方法。
我们治疗了 7 例患者（2 例女性，5 例男性；年龄 27-68 岁）。2 例诊断为黏液囊肿，5 例诊断为黏液囊肿。5 例患者的黏液囊肿向颅腔和眼眶扩展，或向筛窦和眼眶扩展。另外 2 例黏液囊肿向筛窦、蝶窦和上颌窦扩展，向颅腔和眼眶扩展。手术目的是切除黏液囊肿或黏液性囊肿，并防止复发。
7 例患者的术后过程均顺利，所有症状逐渐消退。在 10 个月至 8 年的随访期间，所有患者均无复发，也未发生任何副鼻窦炎症事件。
对于穿透颅腔和眼眶的额窦黏液囊肿或黏液性囊肿的治疗，包括以下几个阶段：额窦颅底化、彻底切除黏膜、紧密封闭额鼻管、用大蒂骨膜瓣将开放的副鼻窦气房与颅腔隔开。
