Comparison of surgical and audiological outcomes of endoscopic and microscopic approach in stapes surgery
Endoscopic versus Microscopic Approach in Stapes Surgery
Objective: The main objectives of the present study were to compare the surgical and audiological outcomes of endoscopic and microscopic approach in stapes surgery.
Methods: Sixty-one patients who underwent the stapes surgery with the endoscopic and microscopic approach between January 2012-November 2018 were included in the study. Patients were divided into two groups as a Group-I (endoscopic) and Group-II (microscopic). The audiometric measurements, duration of surgery, intraoperative findings and complications were recorded and evaluated retrospectively.
Results: Mean operative time for the Group-I and II was 45.1±8.4 minutes and 48.7±5.6 minutes, respectively (p>0.05). The preoperative and postoperative average air-bone gap in the Group-I was 27.8±7.2 dB and 8.7±3.4 dB and these values in Group-II were 30.2±5.1 dB and 7.4±4.8 dB, respectively (p<0.001). The requirement of chorda tympani nerve manipulation and scutum curettage were significantly less in Group-I as compared Group-II (p<0.05). Dysgeusia and postoperative pain were observed significantly higher ratios in Group-II relative to Group-I (p<0.05). There was no significant difference between endoscopic and microscopic approach in stapes surgery in terms of difficulty of prosthesis insertion (p>0.05).
Conclusion: Endoscopic stapes surgery provides comparable audiological outcomes, shorter operative times, fewer complications rates, and more minimally invasive surgery, relative to the microscopic approach.
