The endoscope allows for better inspection for cholesteatoma in cases with chronic otitis media, better access to selective epitympanic poor ventilation and secondary selective chronic otitis media, better visualization of anterior poor ventilation of the mesotympanum (reestablishing adequate ventilation to the mesotympanum), better visualization and reconstruction of anterior tympanic membrane perforations, allows use of Sheehy's lateral graft tympanoplasty through a transcanal approach, and increases the odds of preoperative detection of ossicular chain disruption associated with perforations.
对于慢性中耳炎患者，内窥镜有助于更好地检查胆脂瘤，更便于处理选择性上鼓室通气不良和继发性选择性慢性中耳炎，能更清晰地观察中鼓室前部通气不良情况（恢复中鼓室的充分通气），更清晰地观察和修复鼓膜前部穿孔，允许通过经耳道途径进行希伊氏外侧移植鼓室成形术，还能增加术前检测出与穿孔相关的听骨链中断的几率。
