Image-guided nasal and skull base surgery: a case-control study




The objective of this study is to evaluate the efficacy of image-guided systems in nasal and skull base surgeries.

Study design

This is a prospective case–control study.

Materials and methods

A total number of 24 patients were included in this study. The relevant preoperative, operative, and postoperative records were collected and analyzed.


The mean total operative time was greater for the image-guided surgery group (130 min; range 95–160 min) than for the control group (119 min; range 85–150 min). However, the mean actual operative time was less for the image-guided surgery group (93 min; range 65–120 min) than the control group (99 min; range 70–130 min). The image-guided surgery group had no major complications. However, the control group had three major complications (25%). The average estimated blood loss was higher for the image-guided surgery group (395 ml; range 130–1100 ml) than the control group (380 ml; range 100–950 ml).


Image-guided system may reduce the complications associated with endoscopic sinus surgery and allow for a more thorough operation.
