OBJECTIVE: To evaluate early results on hygiene, safety and functional outcome in a population undergoing a canal wall up technique with bony obliteration of the mastoid and epitympanic space (CWU-BOT) for extensive cholesteatoma, performed by a single surgeon. This study compares different techniques of tympanic membrane reconstruction, viz. allografts and autografts.
PATIENTS: A consecutive series of 61 ears with acquired cholesteatoma treated with primary or revision CWU-BOT surgery from 2009 to 2014.
INTERVENTION: Obliteration was performed by the use of cortical bone-chips and bone pâté. Patients were followed up with micro-otoscopy and MRI with diffusion-weighted imaging. Ossicular reconstruction was performed using a remodelled autologous or allogenic incus or malleus.
MAIN OUTCOME MEASURES: Residual and recurrence rate and short- and mid-term hearing outcome prior to any revision tympanoplasty were analysed, the effect of type of tympanic membrane reconstruction was considered.
RESULTS: 44 Ears were primary cholesteatoma cases, 17 cases were referred for revision surgery. Mean postoperative follow up was 45 months (SD 18.08) and mean follow-up until the last non-EP DW MRI 42 months (SD 17.72). Recurrent disease was present in 3%, no residual disease was present. An AC gain was seen in 75% of all ears undergoing ossicular reconstruction.
CONCLUSION: Reproducible safety, hygiene and hearing results with limited recurrence and residual disease can be obtained by younger otologic surgeons performing the BOT-CWU for extensive cholesteatoma while using a variety of grafts for tympano-ossicular reconstruction. The tympano-ossicular allograft nevertheless shows superior hearing results when a mobile intact stapes is present.
LEVEL OF EVIDENCE: Level 4.
