“…Our underwater drilling approach is different from that described by Yamauchi et al 20 in 2014, as they achieved underwater drilling by injecting water into the cavity. At the same time, our underwater drilling approach is also different from that described by Yamauchi et al 21 in 2017 and Nishiike et al 22 in 2019, as they achieved underwater drilling by scrubbing and cleaning the lens under endoscopy. To achieve underwater drilling, we used a common otological drill with a water irrigation hole that could be connected to the pressure infusor.…”

Objective This study aimed to analyse the differences between underwater continuous drilling and traditional intermittent drilling for attic cholesteatoma. Methods The clinical data of 61 patients with attic cholesteatoma who underwent an endoscopic approach procedure were analysed. Forty patients underwent underwater continuous drilling (group A), and 21 patients underwent traditional intermittent drilling (group B). Results The operation time was 64.61 ± 12.90 minutes in group A and 79.60 ± 16.81 minutes in group B (p < 0.05). The anaesthesia time was 102.69 ± 17.93 minutes in group A and 119.82 ± 19.28 minutes in group B (p < 0.05). The dry ear time, the hearing improvement rate and the post-operative complications were no different in the two groups. Conclusion Group A and group B had no differences in surgical outcome or hearing recovery. However, treatment in the former group resulted in a significantly shortened operation and anaesthesia time.

There has been a rapid increase in endoscopic ear surgery for the management of middle ear and lateral skull base disease in children and adults over the last decade. In this review paper, we discuss the current trends and applications of the endoscope in the field of otology and neurotology. Advantages of the endoscope include excellent ergonomics, compatibility with pediatric anatomy, and improved access to the middle ear through the external auditory canal. Transcanal endoscopic ear surgery has demonstrated comparable outcomes in the management of cholesteatoma, tympanic membrane perforations, and otosclerosis as compared to microscopic approaches, while utilizing less invasive surgical corridors and reducing the need for postauricular incisions. When a postauricular approach is required, the endoscopic-assisted transmastoid approach can avoid a canal wall down mastoidectomy in cases of cholesteatoma. The endoscope also has utility in treatment of superior canal dehiscence and various skull base lesions including glomus tumors, meningiomas, and vestibular schwannomas. Outside of the operating room, the endoscope can be used during examination of the outer and middle ear and for debridement of complex mastoid cavities. For these reasons, the endoscope is currently poised to transform the field of otology and neurotology.

“…9,10 While endoscopic middle ear surgery has gained increasing popularity in the late 1990s, 11 a novel technique reported by Yamauchi et al as underwater endoscopic ear surgery was proposed to repair superior canal dehiscence and labyrinthine fistulas with good results and has the advantages of preservation of the inner ear function and clear operative view. 12,13 This technique provides a clear operative field without the need for suction and protects the inner ear from unexpected aeration that might lead to functional damage.…”

Cholesteatoma Surgery With a Dehiscent High Jugular Bulb Treated With Surgery Assisted With Underwater Endoscopy: A Case Report

et al. 2021

A dehiscent high jugular bulb would be a pitfall in middle ear surgery especially for cholesteatoma. We report a case of cholesteatoma attached to a dehiscent high jugular bulb successfully treated with surgery assisted with underwater endoscopy. To the best of our knowledge, no previous study has reported a case of cholesteatoma with dehiscent high jugular bulb treated with surgery assisted with underwater endoscopy. Owing to the risk of jugular bulb injury, underwater endoscopy is a good indication for middle ear cases with a dehiscent high jugular bulb to obtain a clear operative field and avoid an unexpected air embolism.
