Abstract
INTRODUCTION: Myringoplasty is a common otological procedure indicated in mucosal chronic otitis media. Controversy exists about the condition of the middle ear as a prognostic factor in myringoplasty. The following study intends to emphasis on identifying the efficacious treatment approaches via determining the surgical outcomes of myringoplasty in dry and wet ear in COM within the study period of six month. OBJECTIVES: 1. To Determine the hearing status before and after the surgery. 2. Graft uptake rates in the patients with chronic perforation of tympanic membrane with and without active discharge. MATERIALS AND METHODS: Study Design: The study design employed Descriptive study- Pre and Post design. The pre and post design was carried out by determining the hearing status prior to the advent of the surgery. Study Settings and Duration: This study was conducted in the Department of otorhinolaryngology, Karpaga Vinayaga Institute of Medical Sciences and Research Centre and the duration of the study is six months from February to July 2018. Study Population: The patients visiting the outpatient department of ENT, Karpaga Vinayaga Institute of Medical Sciences and Research Centre, with features suggestive of chronic suppurative otitis media within the period of study period was selected as study population. The variables that have been used to assess the differences between dry and wet ear are the age, gender, ear discharge status, perforation size, preoperative hearing loss, postoperative graft uptake and hearing gain. INCLUSION CRITERIA: ● Age group of 20 – 50 years. ● COM with small/ moderate / large /subtotal central perforation. ● 30 patients with dry ear for a minimum period of 3 months prior to surgery for DRY EAR GROUP and 30 patients with mucoid discharge at the time of surgery after 1 week of antibiotics will be included in the WET EAR GROUP. ● Pure conductive deafness in tuning fork tests. ● Audiometry revealing conductive deafness ranging from 25dB to 45 dB of hearing loss. ● Adequate cochlear reserve function. ● Patent Eustachian tube. EXCLUSION CRITERIA: ● Patients having any focal sepsis. ● Patients with mixed or sensory neural hearing loss. ● Patients having erosion of ossicles or ossicular discontinuity requiring ossiculoplasty. ● Middle ear with granulations( UNSAFE EAR). ● Patients having diabetes and hypertension. RESULTS AND OBSERVATION: The graft uptake rate in dry ear is found to be slightly better compared to wet ear group and the statistical difference is found to be partially significant. The postoperative hearing gain in both the dry and wet ear groups are comparatively same and the difference is found to be statistically insignificant. CONCLUSION: The myringoplasty success is not adversely affected by the mucoid ear discharge at the time of myringoplasty, and success rates are comparable to those of the myringoplasty surgeries performed in the case of inactive ears.
