Assessment on the results of hearing improvement achieved through surgery, with partial ossicular reconstruction prothesis using bioceramic and autograft bone in patients with chronic otitis media

ABSTRACT

Background: In Viet Nam, chronic otitis media is a relatively common disease, accounting for 2-4% of the population. The most common sequalae of chronic otitis media is hearing deficiency. One of the most severe hearing deficiency causes of chronic otitis media is ossicular damages. In developed countries, the partial ossicular reconstruction prosthesis by various materials is relatively common.The partial ossicular reconstruction prosthesis is still limited in Viet Nam.Objectives: To assess the results of hearing improvement after the surgery of partial ossicular reconstruction prothesis and compare the effects of bioceramic and autograft bone. Subjects and method: A study was performed on 135 patients with chronic otitis media who were submitted to partial ossicular reconstruction prostheses with bioceramic and autograft bone at the National Ear Nose Throat Hospital. This was a prospective study. Results: PTA was 54.5 +/- 12.6 dB for four frequencies (0.5, 1, 2, and 3 kHz) in pre-operation, compared to 33.8 +/- 12.8 dB at 6 months after the operation. The ABG improvements for four frequencies and PTA with bioceramic and autograft bone were 18.28 +/- 11.85 dB, 17.99 +/- 10.42 dB, and 18.46 +/- 12.26 dB, 18.81 +/- 11.56 dB, respectively. Conclusions: The hearing levels and ABG were better in post-operation than those in pre-operation. The improvements of hearing levels after the ossiculoplasty using bioceramics was similar to those using autograft bone.
