Abstract

CWD (canal wall down) mastoidectomy is considered the best method to treat chronically discharging ear. This technique shows its efficacy in eradicating the disease process from the middle ear cavity. However, it contributes to the formation of a large cavity, which causes several problems. To get rid of these problems, mastoid obliteration is done.

Highlights

canal wall down (CWD) mastoidectomy is considered the best method to treat chronically discharging ear
It results in the formation of a mastoid cavity, which is unnatural and anatomically and physiologically unacceptable
A common potential problem with traditional canal wall down (CWD) mastoidectomy procedures in treating cholesteatoma is the long-term morbidity associated with discharging cavities [3,9]

Summary

Introduction

CWD (canal wall down) mastoidectomy is considered the best method to treat chronically discharging ear This technique shows its efficacy in eradicating the disease process from the middle ear cavity. It contributes to the formation of a large cavity, which causes several problems. The open mastoidectomy technique has been the mainstay of the management of chronic ear disease due to cholesteatoma; this type of surgery cannot be carried on without related consequences. It results in the formation of a mastoid cavity, which is unnatural and anatomically and physiologically unacceptable. The problems that result from an open cavity are as follows: 1- Chronic discharge from the open cavity with the incidence of discharge being 20–60%. 2- Dependence on the surgeon for regular cleaning of the cavity. 3- Episodic vertigo due to exposure of semi-circular canals to the direct caloric stimulation by air and/or water entering the cavity. 4- Unsightly appearance due to a large meatoplasty. 5- Difficulty in placing hearing aids to people who need them [1,2]
