“…To overcome these problems, our novel technique of plugging by underwater endoscopic ear surgery offers a soft surgery approach for preventing inner-ear damage. We previously reported an underwater endoscopic ear surgery technique for closure of a labyrinthine fistula in cholesteatoma 3 . Initially, saline was perfused with a syringe by an assistant, but using the Endo-Scrub Lens Cleaning Sheath and IPC System is more efficient because the surgeon can control the ideal supply of saline.…”

“…Here we propose a method of underwater endoscopic ear surgery that provides a clear operative view for dissection and which can prevent inner-ear damage in the treatment of superior canal dehiscence, as has been found for closure of labyrinthine fistulas 3 . Underwater endoscopic ear surgery does not require suction and so protects the inner ear from unexpected aeration that may damage its function.…”

“…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.…”

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.

“…The benefit of underwater endoscopic ear surgery in cases of labyrinthine fistula closure and superior semicircular canal dehiscence plugging was reported by Yamauchi et al 6 . The purpose of underwater surgery was to preserve inner-ear function during cholesteatoma removal from the labyrinthine fistula.…”

A novel endoscopic hydro-mastoidectomy technique for transcanal endoscopic ear surgery

et al. 2019

BackgroundIn order to remove a cholesteatoma in the mastoid under transcanal endoscopic ear surgery, it is necessary to perform transcanal endoscopic mastoidectomy. Bone dust and blood, however, obscure the surgical field. A novel endoscopic hydro-mastoidectomy technique was developed, in which the operator performs the mastoidectomy ‘underwater’ using a lens cleaning system that provides saline perfusion in the surgical space.MethodsA curved round coarse diamond bur is attached to an otological drill. A lens cleaning sheath is fitted to the endoscope. The surgeon controls the infusion of saline solution by stepping on a footswitch of the power console.ResultsEndoscopic hydro-mastoidectomy washes out bone dust and blood from the surgical field, improving the surgical view during mastoidectomy. Additionally, the operator can easily control the flow of saline perfusion.ConclusionThis technique provides a clear surgical view by washing out bone dust and blood from the surgical area. The setup for endoscopic hydro-mastoidectomy technique is easy and the operator needs only to buy sheaths if they already own the power console, as many otological and rhinological surgeons do.
