Ossicular Reconstruction, Partial Prosthesis, Hearing Impairment
Introduction-According to the World Health Organization, 63 million people in India have significant hearing impairment. Reports of NSSO survey in the year 2001 suggest that there are 291 persons per one lakh population suffering from severe to profound hearing loss.
Methodology- Prospective study conducted among 32 patients came to the outpatient department with complaints of ear discharge and hard of hearing. An informed consent was obtained from all patients following which all our patients were operated under general anaesthesia. A William Wilde postaural incision is made and extended up and temporalis fascia graft was harvested. The incision was deepened and then a T shaped incision was made and periosteum was elevated. Spine of Henle was identified. A meatotomy was done and pinna retracted forwards. Tympanomeatal flap was elevated. Bone work was started in the MacEwan’s triangle and the mastoid antrum reached which is usually located at a distance of 1-1.5cm from the mastoid cortex.
Results- The results were analyzed after following up the patients every week for the first month postoperatively followed by monthly for the next 2 months postoperatively. The collected data were analysed with SPSS software 23.0 Version. There was a male predominance in the study group. In majority of cases the prosthesis that was used was PORP.
Conclusion-Ossiculoplasty gives better results when compared to cases where ossiculoplasty isn’t done. Ossiculoplasty should always be done in patients with conductive hearing loss which is secondary to ossicular pathology.
