ABSTRACT
Objective: To observe the effects on morphology of middle turbinate and olfaction in trasnasal endoscopic sinus surgery and conventional technique in surgery in chronic sinusitis and nasal polyps (stage Ⅰ，Ⅱ)。 Methods: Two groups patients (85 cases, 163 sites) from September 1979 to September 1999 were examined by coronal CT scans of sinus, nasal endoscopy and olfctory test preoperative and postoperative. Of these patients, 52 cases (101 sites) were operated by transnasal endoscopic sinus surgery, 33 cases (62 sites) were operated by conventional technique in surgery respectively. Management of middle turbinate was divided into reserving and resecting two way. Results: In group of endoscopic sinus surgeries (52 cases, 101 sites), the rates of cure, improved and ineffective were 64.4% (65/101), 29.7%(30/101), 5.9%(6/101) respectively by following 6 months; and returning to normal rates of middle turbinate were 63.1% (41/65), 30.0% (9/30), 0.0% (0/6) respectively; and the returning to normal rates of olfaction were 66.2% (43/65), 36.7% (11/30),0.0%(0/6) respectively; the returning to normal of middle turbinate were 47.4%( 9/19),3.3%(1/13),0.0%(0/13) respectively; the returning to mormal rates of olfaction were 63.2%(12/19),23.3%(7/30),0.0%(0/13) respectively.Conclusion: Endoscopic sinus surgery for chronic sinusitis and nasal polyps can solve ostiomeatal complex anomalism more effectively and raise the cure rates of sinusitis (stage Ⅰ,Ⅱ) than conventional technique in surgery. The morphology middle turbinate and olfaction returned to normal affected directly sinusitis curative rate.
