Retrograde mastoidectomy with canal wall reconstruction: a single-stage technique for cholesteatoma removal.
The goal of this retrospective study was to report the preliminary results of the retrograde mastoidectomy technique with canal wall reconstruction used as a primary treatment method for cholesteatoma. This synthesis of canal wall up (CWU) and canal wall down (CWD) techniques was performed in 70 patients (75 ears; 35 pediatric, 40 adult) with an average 45-month follow-up. Surgical intervention involved removal of a portion of the canal wall for exposure and extirpation of the cholesteatoma, followed by reestablishment of the canal wall during reconstruction in a single stage. This leaves the mucosa relatively undisturbed and limits the extent of canal wall removal, facilitating mastoid aeration and preservation of anatomy. Recurrent disease occurred in 5% of cases. The hearing improvement was statistically significant (p < .05), with an average preoperative 4-frequency pure tone average air-bone gap of 27.2 dB improving to 11.5 dB. No patient had a worsening of hearing. The surgery takes less time than traditional techniques, is reproducible and easily taught, and can be universally applied to all cholesteatoma patients as primary treatment.
