ABSTRACT

The study was done to review postoperative hearing gain of patients with different Middle Ear Risk Index (MERI) undergoing Tympanomastoidectomies with titanium prostheses reconstruction. A Retrospective chart review was performed from September 2009 to December 2011. Of the 17 cases, 9 had moderate MERI while 8 had severe MERI. 9 patients underwent Tympanomastoidectomy with Total Ossicular Reconstruction Prostheses (TORP) and 8 with Partial Ossicular Reconstruction Prostheses (PORP). Hearing gain of 25.31 dB was achieved in cases with moderate MERI compared to 29.37 dB in severe MERI. Less than 20 dB average air-bone gap was achieved in 75% of PORP and 77.77% of TORP reconstructions. In developing countries with limited resources, decision regarding ossicular reconstruction should be made taking into account MERI, intra operative findings and type of surgery. Best results are achieved in cases of CWD with TORP and ICW with PORP.
