Abstract

Background

In 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.

Methods

A 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.

Results

Endoscopic 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.

Conclusion

This 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.
