摘要

Chronic otitis media (COM) is the leading cause of conductive hearing loss, resulting from damage to the eardrum and ossicles due to chronic inflammation in the tympanic cavity. Tympanoplasty is performed to repair a perforated tympanic membrane and, if necessary, reconstruct the ossicles, aiming to prevent reinfection and restore hearing. A pre-operative patch test is conducted to assess ossicular continuity, helping guide post-operative expectations for hearing improvement. “To study the outcome of tympanoplasty in patient of tubo-tympanic type of chronic otitis media and it’s correlation with preoperative and intra operative findings.” 1. To determine the correlation between site of perforation in relation to degree of hearing loss in the tubo-tympanic type of chronic otitis media. 2. To determine ossicular chain status and improvement of Air–Bone gap pre operatively using patch test. 3. To correlate pre-operative and intra operative ossicular chain status with post operative hearing acuity. The study was conducted at the Department of Otorhinolaryngology, Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana, Haryana, India, over 18 months (2022–2024). It included 100 cases of inactive chronic otitis media undergoing tympanoplasty. Pre- and post-operative audiometry (PTA) was performed, and graft uptake and hearing improvement were assessed during follow-up at 1 week, 1 month, and 3 months post-operatively. Graft uptake was specifically evaluated at 1 and 3 months. Our study found that the most common site of perforation was ASQ  +  AIQ  +  PSQ  +  PIQ, with a mean pre-operative PTA of 41.29 ± 8.47  dB. The pre-operative patch test effectively predicted ossicular chain status, with a mean hearing gain of 9.72 ± 3.92 dB. Intraoperatively, ossicular integrity was confirmed in patients showing hearing improvement post-patch test. At 3 months post-operatively, the mean hearing threshold was 23.08 ± 8.38 dB. In our study we concluded that, a simple OPD based Paper patch test is helpful in predicting the ossicular chain status and probable surgical outcome for the patient. Patients with large central perforation involving all the four quadrants has maximum hearing loss. Tympanoplasty surgery with or without cortical mastoidectomy is effective in protecting the middle ear from any further disease and improved the hearing acuity of the patient post operatively.
