The application of endoscope and microscope in the stapes surgeries
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 O-tolaryngology 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 malfor-mations 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 pro-found sensorineural hearing loss in both groups.Conclusion:Endoscope is more suitable for patients who are eval-uated with no severe stapes malformation,or less manipulation of drilling the bone.It could also reduce the hospi-tal visit post-operation.Patients with narrow ear canal or severe middle ear malformation are recommended to per-form the surgery with microscope,because it provides the chance of manipulation with 2-hands of surgeons.
