Objective:To compare the application of endoscope and microscope in all kinds of stapes surgeries. Methods:Fifty-nine stapes surgeries have been collected from April 2020 to May 2023 in Senior Department of Otolaryngology Head and Neck Surgery, Chinese PLA General Hospital, Chinese PLA Medical School. Hearing level, hospital stay post-operation, times of hospital visit post-operation, etc. have been compared between the endoscopic group and microscopic group. Patients who were failed to place the stapes prosthesis because of the poor exposure of the oval window have been analyzed. Results:Otosclerosis was the most common diagnosis in both groups. There was 1（1/23） middle ear malformation in the endoscopic group and 5（5/36） middle ear malformations in the microscopic group. There were 2 Van Der Hover syndromes and 4 Treacher Collins syndromes in the microscopic group. In the endoscopic group ABG of 10 ears（43.5%） ≤ 10 dB, and ABG of 21 ears（91.3%） ≤20 dB.In the microscopic group ABG of 13 ears（41.9%） ≤ 10 dB, and ABG of 28 ears（90.3%） ≤ 20 dB. There was no statistic difference between 2 groups. Times of hospital visit post-operation in the endoscopic group was less than in the microscopic group（P<0.01）. There was no facial palsy, tympanic perforation or profound sensorineural hearing loss in both groups. Conclusion:Endoscope is more suitable for patients who are evaluated with no severe stapes malformation, or less manipulation of drilling the bone. It could also reduce the hospital visit post-operation. Patients with narrow ear canal or severe middle ear malformation are recommended to perform the surgery with microscope, because it provides the chance of manipulation with 2-hands of surgeons.
