Effect of Common Comorbidities on the Success Rate of Myringoplasty

ABSTRACT

Objective: The aim of the study was to study the effect of common comorbidities on the success rate of myringoplasty.Materials and Methods: A retrospective evaluation of the 40 patients who have undergone myringoplasty for different sizes ofcentral perforation with pure conductive hearing loss of <60 dB were done. Both males and females of age 15–60 years wereincluded in the study. The comorbidities studied were hypertension, diabetes and nasal allergy. Temporalis fascia was usedas the graft and grafting was done by underlay technique. Patients were followed up for 6 months. The influence of variouscomorbidities was assessed by comparing the rates of graft take up and graft retraction.Results: Among the 40 patients we selected, the majority were in the age group of 30–45 years. We had 7 (17.5%) patients withdiabetes mellitus and during the follow-up at 6 months, 28.6% of failure and 14.3% of retractions were observed. (significance?)Among the 9 (22.5%) patients who were hypertensives, we did not find any graft failure. 17 (42.5%) patients had a nasal allergy.We found failures in 23.5% by 6th month and retractions in 17.6%. P value was calculated and was found to be statistically notsignificant.
