Aim:A comparative study of endoscopic assisted versus conventional middle ear and mastoid surgery at a tertiary care teaching hospital. Material and Methods: This comparative study was carried out in the Department of ENT, Cases of chronic otitis media, inactive mucosal disease for tympanoplsty, cases of chronic otitis media, active or inactive squamosal disease for mastoidectomy and patients with the age between 10 to 60 years were included. Total 50 patients; among them 25 cases were of endoscope assisted middle ear surgery and 25cases with conventional microscopic middle ear surgery. Results:In patient of endoscopic assisted tympanoplasty mean pre operative A-B gap was 31.11±4.19 dB while post operative mean A-B gap was 18.25±3.28 dB. In patient of non-endoscopic assisted tympanoplasty mean pre operative A-B gap was 27.16±3.82 dB while post operative mean A-B gap was 19.08±4.56dB. In present study mean pre operative A-B gap was 42.01±2.54dBand 37.16±3.12 dB for endoscopic assisted mastoidectomy and non-endoscopic assisted mastoidectomy respectively. While post operative mean A-B gap was 34.11±3.41dB and 29.42±4.14dB for endoscopic assisted mastoidectomy and non-endoscopic assisted mastoidectomy respectively. In present study mean A-B gap closure for endoscopic assisted tympanoplasty was 14.06±2.43dB, while 10.68±1.78dB for non-endoscopic assisted tympanoplasty. Mean A-B gap closure for endoscopic assisted Mastoidectomy was 9.25±1.12dB, while 9.14±2.32dB for non endoscopic assisted mastoidectomy. Conclusion: This study concluded that the endoscope can be successfully applied to ear surgery for most of the ear procedures with a reasonable success rate both in terms of perforation closure and hearing improvement and with minimal exposure.
