Background: Chronic suppurative otitis media (CSOM) is an inflammatory process of the mucoperiosteal lining of the middle ear space and mastoid. The present study compared over underlay graft technique with conventional underlay myringoplasty in patients with mucosal CSOM. Materials & Methods: 84 patients diagnosed with chronic suppurative otitis media of both genders were divided into 2 groups of 42 each. Group I patients were operated by conventional underlay myringoplasty and group II patients were operated by over underlay myringoplasty. Parameters such as status of graft, size of perforation, degree of hearing loss etc. was compared in both groups. Results: Group I had 28 males and 16 females and group II had 20 males and 22 females. The site of perforation was grade IV seen in 12 in group I and 10 in group II and V 30 in group I and 32 in group II. Degree of hearing loss was mild seen in 34 in group I and 30 in group II, moderate 8 in group I and 12 in group II, air born gap pre-op was 34.2 dB in group I and 38.6 dB in group II and post- op was 19.6 dB in group I and 19.7 dB in group II. Graft status was graft taken up in 40 in group and 41in group II and graft failure was 2 in group I and 1in group II. The difference was significant (P< 0.05). Conclusion: Over underlay technique has advantages of graft uptake rate and found to be better than conventional underlay myringoplasty.
