Abstract Objective: To analyze the anatomic variations of superior attachment of uncinate process(SAUP) and drainage pathway in patients with chronic sinusitis by MSCT, and to explore the influence on the frontal sinusitis. Methods: Two hundred and twenty-two sides of 111 patients with sinusitis who were candidates for endoscopic sinus surgery and underwent MSCT scanning were collected. The incidence of various types of SAUP, and the correlation between SAUP and internal and external drainage of uncinate process were determined by MSCT. The difference of frontal sinusitis between internal and external drainage groups was analyzed. Results: Among 222 SAUP types, the most common types of SAUP were type Ⅰ(55%), type Ⅳ(19.8%) and type Ⅴ(12.6%). In the evaluation of frontal sinusitis, 88(39.6%) had frontal sinusitis, 57 internal drainage(46.7%) and external drainage 31(31.0%). In patients with chronic sinusitis, the frontal sinusitis was more common in the internal drainage channels of SAUP than in the external drainage(46.7% vs 31.0%, P＜0.05). Conclusions: Before nasal endoscopic surgery, we need to clarify the anatomical variation of SAUP, and the changes in the location of the outflow tract of frontal sinus caused by SAUP typing affect the incidence of the frontal sinusitis. In patients with chronic sinusitis, frontal sinusitis is more likely to occur when the frontal sinus drainage area is internal drainage than external drainage.
