RESUMEN
Objective: To compare the results of permeatal approach without raising the tympano-meatal flap to end-aural or post-aural approach in myringoplasty
Methods: This Quasi-experimental study was carried out in CMH [Combined Military Hospital] Peshawar, from August 2006 to July 2013. Three hundred fifty patients of chronic suppurative otitis media [CSOM] with dry central; small, medium and large perforations were selected
They were divided into two groups depending upon the type of approach. In Group-A [n-200]; permeatal approach without raising tympano-meatal flap was used; while in Group-B [n-150] end-aural or post-aural approach was used. Subjects were followed up for two years; graft take was checked regularly by examinations of ear under microscope. Data was collected on structured Performa and analysed by SPSS-17
Results: Male and female were 74% and 26% respectively; Age ranged from 15 to 46 Years. There was no significant difference in the graft success at the end of two years in Group-A [80%] and Group-B [85%] [p-0.261]. Type of approach had a significant impact on duration of surgery [p<0.001] and post-operative recovery time [p<0.001]
Conclusion: The permeatal approach and end-aural/post-aural approach had almost equal graft success rates, but former is more useful as it causes lesser morbidity, decreased post-operative hospital stay and reduced operative time. It is under-utilized and should be employed more frequently
