Title: ONE YEAR PROSPECTIVE STUDY TO COMPARE UNDERLAY AND OVERLAY TECHNIQUES OF MYRINGOPLASTY
Abstract: Tympanic membrane perforation may be traumatic in origin or due to CSOM which may not heal spontaneously.Over the years various modalities of treatment have evolved for the treatment of this.Primary aim of the treatment is to control and eliminate the foci of infection.The closure of tympanic membrane perforation with different graft materials restores the vibratory area of the membrane, gives round window protection, reduces susceptibility of the middle ear mucosa to infection and improves hearing.Two basic techniques have come up in which the graft is placed either over the drum remnant or under the drum remnant and the techniques are called overlay and underlay respectively.The present study is an attempt to compare the results of both techniques in a tertiary care hospital.Tympanic membrane perforation may be traumatic in origin or due to CSOM which may not heal spontaneously.Over the years various modalities of treatment have evolved for the treatment of this.Primary aim of the treatment is to control and eliminate the foci of infection.The closure of tympanic membrane perforation with different graft materials restores the vibratory area of the membrane, gives round window protection, reduces susceptibility of the middle ear mucosa to infection and improves hearing.Two basic techniques have come up in which the graft is placed either over the drum remnant or under the drum remnant and the techniques are called overlay and underlay respectively.The present study is an attempt to compare the results of both techniques in a tertiary care hospital.
