To perform tympanoplasty with mastoidectomy in chronic supporative otitis media cases. To periodically evaluate the post operative benefit in terms of graft take up and hearing improvement. METHODS: A prospective study where 42 patients with CSOM underwent tympanoplasty with cortical mastoidectomy in department of ENT at Katuri Medical College and Hospital. Underlay technique with temporalis fascia graft, cortical mastoidectomy was done in all cases. Follow up at 3 months, 6 months and 1year was done for graft takeup and hearing improvement. RESULTS: Post op AB gap closure at the end of 1 year follow-up below 10 db was achieved in 74% of cases, between 11-20 db was achieved in 21% of cases. Graft uptake at the end of 1year was 88%. CONCLUSION: Our study emphasizes the fact that overall satisfactory hearing outcome and graft uptake can be achieved after tympanoplasty with cortical mastoidectomy in dry and quiescent ears.

Objective of the present study is to know the effect of cell phone usage on hearing thresholds. MATERIAL AND METHODS: Seventy students from 20-30 years of age were divided into two groups. Those using cell phone for more than one hour a day for past 5 years form the test group and those using for less than one hour for less than 5 years form the control group. Pure tone audiometry was done on all the subjects. RESULTS: There was a significant increase in hearing thresholds at all frequencies for both air conduction and bone conduction in both right ear and left ear, except for bone conduction at 4KHz. CONCLUSION: There was a significant increase in hearing thresholds in mobile phone users associated with duration of usage.
