“…A study conducted by Shiromany et al had patients in age range from 12 to 64 years and mean age was 26.7 ± 10.18 years (5). The mean age of patients in the present study was comparable with the other studies (6)(7)(8).Maximum patients i.e. 40% (24/60) were in age range of 18-20 years.…”

“…The hearing loss also varies according to the size and site of the perforation. The posterior quadrant perforation has slightly more hearing loss than the anterior ones [1].…”

The hearing threshold in atrophic tympanic membrane is assessed in 35 individuals. Assessment of hearing threshold in patients having atrophic tympanic membrane. Prospective clinical study. Tertiary referral centre. Thirty-five patients who had atrophic tympanic membrane in one ear and normal tympanic membrane of the other ear which was used as control, were selected Hearing threshold of patients having atrophic tympanic membrane. Twenty-nine patients with atrophic tympanic membrane had absolutely normal PTA of the ear and the opposite ear with normal tympanic membrane had similar normal PTA. Majority of the patients with atrophic tympanic membrane have normal hearing.

“…Besides ossicular integrity, there are other determinants of hearing loss in dry perforated ears, such as middle ear volume and area of perforation. Mehta et al (10) showed that hearing loss increases with increasing perforation size but that the location of the perforation had no effect. They also mentioned that hearing threshold had an inverse relation with middle ear volume.…”

Objective: High-resolution computed tomography (HRCT) has gained wide acceptance in diagnostic work-up of suppurative chronic otitis media. Most ear surgeons order HRCT to make a rational operative plan, especially in the presence of symptoms, such as refractory otorrhea with bad odor, epithelial debris at retraction pockets, and defects in bony walls of the middle ear. The aim of this study was to show the lack of necessity of preoperative HRCT by evaluating its predictive value in patients who underwent type I tympanoplasty. Methods:The study included a patient group who underwent tympanoplasty with dry perforation and normal middle ear mucosa. The intraoperative findings of 43 patients were compared with preoperative HRCT and audiogram findings. Results:There was no significance between preoperative air conduction threshold and existence of ossicular erosion in HRCT. HRCT incorrectly predicted the presence of cholesteatoma in two patients. The positive predictive value of HRCT in detecting soft or granulation tissue was 4/14 (28.57%). The sensitivity and specificity of HRCT in the diagnosis of ossicular chain status were 9.09% and 90.62%, respectively. Conclusion:HRCT plays an important role in the assessment of patients with suppurative chronic otitis media and cholesteatoma. However, preoperative HRCT in patients who have undergone type I tympanoplasty is not necessary. It has no benefit and also leads patients to unnecessary radiation exposure.
