<p><strong>Background</strong>:<strong> </strong>The effect of mobile phone radiation on human health is the subject of recent interest and study as a result of the enormous increase in mobile phone usage throughout the world. The present study was designed with an objective to study the effect of mobile phones on hearing.</p><p><strong>Methods</strong>: This cross sectional study involved cases in the age group of 18 to 45 years attending the out-patient department of ENT at Chhatrapati Shivaji Subharti hospital, Meerut. A total of 85 patients (mobile phone users) were taken for the study October 2018 to July 2020. Subjects with usage of mobile phones (smart phones) for a minimum of 2 hours a day and a minimum of 1 year duration (with or without ear phones), normal healthy individuals with no systemic disease, normal tympanic membrane with no prior external, middle/inner ear disease or discharge or trauma and subjects with type a tympanogram (on tympanometry) were included in the study. Degree of deafness was graded according to WHO classification, 1980</p><p><strong>Results</strong>: Statistically significant p value was observed (&lt;0.001) while comparing SNHL with hours of exposure and years of exposure. Statistically significant p value was observed (&lt;0.05) while comparing hours of exposure with Tinnitus. Statistically insignificant p value was observed while comparing hours and years of exposure with other associated complaints; aural fullness, ear ache (otalgia) and warmth sensation in ear.</p><p><strong>Conclusions</strong>: The present study shows an increase in the hearing threshold of the ear exposed to the prolonged use of mobile phones.</p>

<p class="abstract"><strong>Background:</strong> Isolated cleft palate and cleft palate and cleft lip patients have poor Eustachian tube function which results in hearing impairment that too in the speech formative years. Aim of study was to evaluate tympanometric findings in patient of cleft palate and effect of palatoplasty on both short term and long term postoperatively.</p><p class="abstract"><strong>Methods:</strong> The subjects consisted of patients attending the cleft lip and palate clinic. This was a combined clinic consisting of department of plastic surgery, department of ENT and department of dental surgery held every month at a tertiary care hospital in Delhi. Study consisted of three groups of patients namely preoperative group, postoperative group and pre-postoperative group.</p><p class="abstract"><strong>Results:</strong> No significant difference was observed in tympanometric abnormalities in cases of combined cleft lip and palate as compared to isolated cleft palate. After age of 5 months once changes of OME has set in there was no significant change in middle ear findings irrespective of palatal repair.</p><p class="abstract"><strong>Conclusions:</strong> There is a very high prevalence of otitis media with effusion in these patients. The changes do resolve spontaneously after age of seven, this perhaps is due to combined effect, growth, development and l maturity of Eustachian tube and palatal surgery rather than palatal surgery alone.</p><p> </p>
