Determinants of variable hearing loss in patients with chronic suppurative otitis media

To determine the impact of ear discharge, duration size and site of tympanic membrane perforation on hearing loss. Cross-Sectional prospective study. Baqai Medical College and Abbasi Shaheed Hospiatl, Department of Ear Nose and Throat and Head and Neck Surgery from December 2010 to November 2011. Sixty six patients of chronic suppurative otitits media [CSOM] aged between 09 to 60 years of age were included in the study. After history and examination, pure tone audiometry was done .Statistical analysis of the collected data is done using SPSS 16 program. Patients with 107 perforated tympanic membrane, 40 males and 26 females were included in the study. Bilateral tympanic membrane perforation were seen in 41 patients, right sided perforation in 10 and left sided in 15 patients respectively. Out of total 107 perforations, 58 were large central[54.2%]and 49 were small[45.8%]. 100 perforations [93.5%] were anteriorly located and 07 [6.5%] were posterior. The size of the perforation was not a determinant of hearing loss though the site of the perforation was associated with significant degree of hearing loss. Hearing loss increased with the chronicity of the disease. The location of perforation on the tympanic membrane and the duration of ear discharge have significant effect on the magnitude of hearing loss while the size of perforation does not affect the hearing level significantly

Comparison between dissection and bipolar diathermy method tonsillectomy

To compare dissection method and diathermy method tonsillectomy in terms of intraoperative mean blood loss, time taken for surgery and frequency of post operative bleeding. It was a grass experimental study carried out at Liaquat National Hospital, Karachi from January 2004 to January 2005. Patients of ages between 5 years and 25 years were selected from the out patient department. Sampling technique was convenient sampling. Sample was of 100 patient. First 50 patients were selected for dissection method [Group A] and the last 50 patients for bipolar method tonsillectomy [Group B]. Data collection procedure was interview and observational facts. Data was analyzed by using SPSSS version 10. For mean comparison, student's test was used. Significance of the test was taken at p<0.05. The difference in result between dissection method tonsillectomy and diathermy method tonsillectomy was statistically significant [P<0.001] in terms of intraoperative blood loss and time taken for surgery. Regarding postoperative hemorrhage, the difference between diathermy and ligation was insignificant. Tonsillectomy with bipolar diathermy was a better and safer technique as compared to ligation method especially in terms of intraoperative blood loss and time taken for surgery. The frequency of postoperative bleeding was similar in both methods

study of hearing levels in children of rural and urban setups

To assess the hearing levels of children belonging to two different environmental set ups. A Comparative analysis. ENT department Fatima Hospital, Baqai Medical University June 2006 to Nov. 2006. Study includes 100 students of Saleemullah Fahmi Primary School and equal number of Cadets of Baqai Cadet College Gadap. Hearing levels of these two groups of children were assessed and recorded with the help of pure tone audiometer [PTA]. It was found that the hearing levels of the students of Baqai cadet college were noticeably better i.e. 59/100 having normal hearing, hearing grade-I, and 41/100 having mild loss, hearing grade-Il, than the students of Saleemullah Fahmi primary school where 41/100 having mild loss i.e. hearing grade-I and 58/1 00 moderate loss hearing grade-Il and only 01/100 having severe bilateral loss i.e. hearing grade-III. The hearing assessments of 200 sample students from rural and urban background [divided into two equal groups] were found to have different levels of hearing without any detectable pathology in their hearing apparatus
