Role of computer aided navigation system for surgical treatment of extensive sinonasal polyposis

Lathadevi H. Thotappa

Abstract


Background: The aim of the study was to study the role of computer aided endoscopic sinus surgery for treatment of extensive sinonasal polyposis by comparing cases with and without navigation.

Methods: A prospective study of 75 patients with extensive nasal polyposis attending outpatient section of department of ENT, BLDE University’s Sri BM Patil Medical College, Hospital, Vijaypur was done from January 2015 to December 2017. 37 cases were randomly subjected to surgery with navigation. Other group included 38 cases which underwent surgery without navigation.  

Results: A total of 75 cases of which 39 were males and 36 females with an age range of 9-76 years. Patients were studied for preoperative and postoperative SNOT-22 symptom scores. These values showed significant improvement with p<0.001. The comfort level of the surgeon intraoperatively was good in 89.18%, medium in 10.8% and bad in 0% cases in navigation guided surgeries. Whereas in surgeries without navigation, it was good in 78.9%, medium 10.52% and bad in 10.52% cases. Intraoperatively disease clearance adequacy was partial in 1 case (2.7%) and total in 36 cases (97.3%). In cases without navigation, the scores were 4 (10.5%) partially cleared, 34 (89.5%) totally cleared. No major (0%) and one minor complication, 1(3%) in surgery with navigation occurred. In group without navigation guided surgery, Major complication was 13% and minor was 11%. These values are indicative of P value 0.021.

Conclusions: The computer aided navigation guided surgery is a necessary tool in cases of extensive lesions like sinonasal polyposis.
