目的：鼻内窥镜下的鼻腔鼻窦手术在彻底切除病变组织基础上尽可能不损伤鼻腔及鼻窦的解剖结构，最大限度地保留鼻腔和鼻窦的基本功能。方法：采用功能性鼻内窥镜进行鼻腔、鼻窥手术27例。结果：术后随访，13例鼻息肉并鼻窦炎，5例慢性肥厚性鼻炎全部恢复正常通气功能。9例鼻中隔偏曲全部治愈。鼻内窥镜手术时原则上应该保留中鼻甲。但对于筛窦病变较重，气化的中鼻甲有积脓及呈息肉样改变者则不应再保留。结论：应用鼻内窥镜行鼻腔鼻窦手术损伤小、疗效佳、是鼻腔、鼻窦手术有前景的手术方法。
OBJECTIVE: Nasal sinus surgery under nasal endoscopy can completely destroy the anatomical structure of the nasal cavity and paranasal sinuses without damaging the nasal cavity and paranasal sinuses as far as possible, so as to keep the basic functions of the nasal cavity and paranasal sinuses. Methods: Functional endoscopic nasal and nasal gastrectomy in 27 cases. Results: All patients were followed up for 13 cases of nasal polyps and sinusitis, 5 cases of chronic hypertrophic rhinitis returned to normal ventilation. 9 cases of nasal septum deviation all cured. Nasal endoscopic surgery in principle should retain the middle turbinate. But for the ethmoid sinus lesions heavier, gasification of the middle turbinate with suppuration and polypoid change should not be retained. CONCLUSION: Nasal endoscopic sinus surgery with small injury and good curative effect is a promising surgical method for nasal and sinus surgery.
