“…Bone pate has been widely used to successfully obliterate the mastoid and epitympanum [21] . We found it better to use than other materials as it is easily collected from the non-infected mastoid cortex.…”

OBJECTIVE:Removing the posterior canal wall or canal wall down mastoidectomy (CWDM) for the management of cholesteatoma remains controversial. We advocate partial removal of the posterior canal wall for complete eradication, followed by canal wall defect reconstruction to restore the normal anatomy and avoid the complications of CWDM. MATERIALS and METHODS:Sixty-four patients with cholesteatoma (71 ears) were included. This study was conducted between 2009 and 2012. Single-stage mastoidectomy was performed by drilling the upper third of the posterior canal wall together with the attic, leaving the remaining lower two-thirds intact. Conchal cartilage was used to reconstruct the upper third of the posterior canal wall. RESULTS:The mean±SD healing time was 7.5±2.3 (range, 4-14) weeks. The mean±SD preoperative and postoperative air bone gaps were 35.8±6.2 dB and 22.9±6.8 dB, respectively. Nearly 84.2% of the patients were followed up for at least 3 years and had dry healthy ears. Complications were noted and statistically examined. CONCLUSION:Single-stage CWDM with reconstruction of the posterior canal wall, ossicular chain, and tympanic membrane is a safe and reliable technique with the advantages of Canal wall up Mastoidectomy (CWUM). Its recurrence rate is 4.2%. Longer follow-up durations are required.

“…Aimed at solving these problems mentioned above, surgeons have attempted reconstruction with a variety of techniques and materials [ 8 ]. Two general strategies have been attempted: reconstruction of an anatomically correct canal wall and complete obliteration of the mastoid cavity [ 8 9 ]. Several surgeons performed staging in CWD procedures with reconstruction, due to the risk of residual cholesteatoma [ 2 9 10 ].…”

ObjectivesWe evaluate the long-term surgical and hearing results using a canal wall down mastoidectomy technique followed by cavities obliteration, canal wall reconstruction and ossiculoplasty without staging.MethodsA total of 44 patients between January 2002 and October 2009 were selected and 27 of them were revision cases. Preoperative and postoperative pure tone average (PTA) and air-bone gap (ABG) were assessed and compared 1 and 4 years after surgery.ResultsThe middle ear was well healed and aerated in 40 patients (90.9%) and the tympanic membrane was intact in 42 patients (95.5%). Recurrent cholesteatoma was found on postoperative follow-up in two of the revision patients (7.4%) but none in the primary patients. Seven patients were found to have partial canal bone absorption, but revision surgery was not required. Over 86.4% of all cases were water resistant. Long-lasting improvement and/or preservation of hearing, with maintenance of PTA-ABG closure in 63.7% of all cases within 20 dB, were obtained.ConclusionThe efficacy of our technique after a canal wall down mastoidectomy is satisfactory, and the rate of complication is acceptably low. We believe that our technique could be a convenient method in disease control and providing an excellent basis for hearing restoration simultaneously.
