Application of endoscopy in otology: Changes over the last 8 years in Check for Korean Otological Society

摘要

Objectives: Despite the worldwide availability of endoscope in otology, it still has not replaced the microscopic surgery as it has for nose surgery. In 2008, we administered a questionnaire on the preference of using otoscopes in Korea. In light of the worldwide availability of endoscopic ear surgery, we have now conducted a more detailed survey to determine if this preference has changed over 8 years.& para;& para;Subjects and methods: A questionnaire consisting of 10 questions was used to survey members of the Korean Oto-logical Society who were actively performing middle ear surgery. The responses to this questionnaire were compared to those from 2008. The study also determined the preference for endoscope use based on the surgeon's experience.& para;& para;Results: The mean surgical experience of the otologists was 12.7 years. Endoscopy for tympanoplasty and tympanomastoidectomy increased over a period of 8 years. In the outpatient clinic, the use of endoscopy also increased ; over 8-year period, it surpassed the microscope as the most preferred diagnostic tool in the outpatient clinic. Greater than half of the operating rooms were equipped with endoscopic sets; however, only 4.5% of otologists acknowledged having endoscopic instruments.& para;& para;Conclusion: Endoscopy for surgery and in outpatient clinic assessment increased in otology in Korea; however, endoscopes have consistently been used as an adjuvant to the microscope to improve visualization of the tympanic cavity rather than as a tool for totally endoscopic ear surgery.
