Outcome of computer-assisted surgery in patients with chronic rhinosinusitis.

Objective: To compare the complication rates and outcome of computer-assisted versus non-computer-assisted functional endoscopic sinus surgery. Methods: We reviewed retrospectively the medical records of 276 patients who had undergone sinus surgery for chronic rhinosinusitis with (n = 108) or without (n = 168) computer assistance, from 1996 to 2004, to determine the incidence of complications and need for revision surgery. Results: The incidence of complications was 6.5 per cent in the computer-assisted group and 6.0 per cent in the non-computer-assisted group (p = 1.00). In the computer-assisted group, 9.2 per cent needed revision surgery, compared with 10.7 per cent in the non-assisted group (p = 0.84). Conclusions: Although our study found no significant difference in complications or revision rates, computer-assisted surgery serves as an important orientation aid during functional endoscopic sinus surgery.
