Myringoplasty – A Rewiev of 438 Cases

The medical records of 438 patients who underwent myringoplasty followed up for a minimum of one year in the period of 1980 and 2015 were revised. Examination under otomicroscope was done of the ear to be operated. This was carried out with a speculum under the operating microscope to be reliably asses the tympanic membrane, site of perforation, to rule out any other pathology and assess the status of ossicular chain. All the patients submitted primary myringoplasty surgery were operated under postauricular, endaural and transcanal approach with overlay, underlay and inlay methods. In the study the patients were divided into three groups depending upon the technique utilized to repair the tympanic membrane. When we compared overlay technique group with underlay technique group, it was observed that overlay technique was no statistically significant difference between these three groups in term of age wise distribution, gender wise distribution, duration of disease and cause of disease, due to matching at the time of selection. In this study the outcome in terms of graft uptake rate was slight better in the overlay technique (94%) as compared to the underlay technique (86.2%), though the difference was statistically insignificant, P>0.05. Patients selection may have had a role in the high success rate in the present study as patients presenting with middle ear pathology were excluded. The complications rate in the present study was quite low, no case in inlay group, three cases of graft lateralization in underlay group, and 19 cases in overlay group. In this study, better results were achieved with overlay technique may probably be due to less surgical manipulation and faster healing process.
