STUDY TO ASSESS THE EUSTACHIAN TUBE FUNCTION BEFORE AND AFTER TYMPANOPLASTY: A COMPARATIVE STUDY.

Aim: aim to assess the eustachian tube function before and after tympanoplasty. Materials and methods: The present prospective comparative study was conducted in the Department of ENT, Sri Krishna Medical College and Hospital, Muzaffarpur, Bihar India .Among 60 patients confirmed with the diagnosis of chronic otitis media. Preoperative PTA and eustachian tube function tests were taken. Patients were then subjected to ear surgery. Results: Majority of patients were young adults the mean age group was 28.16±6.61 years. Of these patients, 55.0% were males and 45.0% were females. Mean preoperative PTA was 40.32±3.41 and post operatively the PTA was 31.41±4.65 improved significantly (p<0.05). Conclusion: The prognosis of middle ear surgery has a direct correlation with the Eustachian tube functions, i.e. good Eustachian tube functions is essential for obtaining a good prognostic value and vice versa.

Abstract Background In the developing nations, the sinonasal region is routinely screened in chronic otitis media, but Eustachian tube is not as it is not cost-effective. Hence, we innovated an inexpensive device named Eustachian barotubometer. Materials and Methods A prospective case–control study was performed on mucosal type of chronic otitis media and traumatic tympanic perforation (100 cases each). Eustachian tube function was assessed by the Eustachian barotubometer (forced and physiological opening) and nasopharyngoscopy. Results Eustachian tube dysfunction was found to be five times higher in cases than controls. Both forced opening function and physiological opening function were poorer in cases than controls. However, the difference was statistically significant only in physiological opening function (p = 0.003). Among the cases with dysfunctional tubes, 86.7% were hypofunctional, whereas 13.3% were totally blocked. Conclusion Eustachian tube function was affected in 15% of cases of mucosal chronic otitis media as compared with controls in this study. This novel device could be conveniently used to help decide the right time to undertake middle ear surgery.

Poor eustachian tube function plays a major role in the pathogenesis of chronic secretory otitis media. This is illustrated by epidemiologic studies of secretory otitis media and long-term studies of treated secretory otitis. Evaluation of hearing results demonstrate that effective preoperative and postoperative tubal function is highly important for good surgical outcome in cases of chronic otitis and cholesteatoma.

Before And After

AbstractObjective:We investigated gustatory changes in patients with chronic otitis media, before and after middle-ear surgery.Methods:This prospective study included 38 patients with unilateral chronic otitis media. We used taste testing solutions to evaluate each patient's taste function. Intra-operative assessments of the chorda tympani nerve were also compared and analysed.Results:Patients with chronic otitis media had significantly worse ipsilateral perception of sour, bitter and salty tastes. In patients with good intra-operative preservation of the chorda tympani nerve, there was significant improvement in gustatory function one month post-operatively, compared with the pre-operative baseline. In patients who sustained intra-operative chorda tympani nerve injury, one month post-operative gustatory function was the same as the pre-operative baseline.Conclusion:Middle-ear surgery for chronic otitis media not only treats the ear but also improves gustatory function in the majority of patients. In patients with intra-operative injury to the chorda tympani nerve, post-operative taste decline is only temporary.
