Abstract:ObjectiveTo explore the application of expanding bilateral sphenoid sinus plasty in the treatment of sphenoid sinus diseases.MethodsFrom Dec 2012 to June 2017, 42 patients suffering from sphenoid sinus diseases were treated by expanding bilateral sphenoid sinus plasty in our department. All the patients were followed up for 6 to 53 months for evaluating the surgical effect and complications. Results15 cases of refractory sphenoid sinusitis were cured with good opening of sphenoid sinus orifice and clean cavity. The rest of the patients underwent complete resection of the lesions. One case of fungal sphenoid sinusitis complicated with intracranial infection and fever received postoperative antifungal therapy for 3 months. Two cases of sphenoid sinus carcinoma and one of sphenoidal chordoma as well as one of olfactory neuroblastoma with sphenoid sinus and intracranial invasion received postoperative radiotherapy. Of all the 42 cases, the symptoms were relieved after operation except hyposmia in 2 and impaired vision in one. No complications such as nasal bleeding, olfactory hypofunction and perforation of nasal septum occurred. Follow up revealed good mucosal epithelization in all the patients with an average epithelization time of 8.6 weeks. Two patients with sphenoid sinus cancer were followed up for 10 months and 14 months, respectively. One with sphenoid sinus chordoma was followed up for 10 months, and another one of olfactory neuroblastoma with sphenoid sinus and intracranial invasion was followed up for 8 months. So far, recurrence occurred in none.ConclusionWith advantages of clearly exposed surgical field, full opening of sinus cavity, high surgical safety, short epithelialization time and intuitionistic postoperative followup, the expanding bilateral sphenoid sinus plasty is worth popularizing for the treatment of sphenoid sinus diseases.
