Abstract:Objective To report 15 cases of endoscopic resection of ethmoid sinus osteoma, to discuss the surgical method and treatment effect of endoscopic resection of ethmoid sinus osteoma, and to summarize the surgical experience of sinus osteoma. Methods The clinical data of 15 patients were retrospectively analyzed, who underwent endoscopic resection of ethmoid sinus osteoma in Department of Otolaryngology Head and Neck Surgery, Wuhan First Hospital from June 2018 to April 2022. All patients underwent paranasal sinus CT examination, nasal endoscopy, nasal resistance examination and ophthalmology related examinations before surgery. All operations were completed by nasal endoscopy under general anesthesia. The specific operation method was determined after the location and scope of ethmoid sinus osteoma were determined according to CT. The ethmoid sinus osteoma was completely removed. After the operation, postoperative patients were reexaminated by the nasal sinus CT and nasal endoscopy, and returned to the outpatient department regularly. Results All of the 15 patients were pathologically confirmed as ethmoid sinus osteoma after operation. CT of the sinus showed that ethmoid sinus osteoma was completely removed. After 5 to 48 months of follow-up, the symptoms of nasal congestion, facial swelling and pain, headache, purulent discharge and hypoesthesia were alleviated or disappeared after operation. No significant intraorbital and intracranial complications occurred, and no recurrence of osteoma was observed. Conclusions Nasal sinus CT can determine the location and scope of osteoma before operation, which provides a good guarantee for endoscopic sinus surgery. Endoscopic resection of ethmoid sinus osteoma is worthy of clinical application. It is effective, safe and minimally invasive，which has a good prognosis.
