Diagnostic Accuracy of Plain Computed Tomography Temporal Bone in Detection of Pre-operative Ossicular Status versus Per-operative Findings in Chronic Otitis Media.

Ossicular destruction is a common phenomenon in chronic otitis media due to an imbalance between osteoblasts and osteoclasts. Computed tomography helps us in the assessment of ossicular status, extent of pneumatization, and early identification of complications. This study aims to check the diagnostic accuracy of computed tomography temporal bone for the detection of ossicular erosion in comparison with the surgical findings taken as a gold standard. The use of this investigation as an adjunct can prove to be helpful in planning mastoid exploration as well as a primary reconstruction surgery especially in mucosal and early squamosal diseases. It's a cross-sectional validation study done on 50 patients with chronic otitis media (both mucosal and squamous type) from July 2022 to November 2023. Patients underwent CT scanning of temporal bone and ossicular status was reported by the radiologist. Later on, mastoid surgery was carried out and per operative findings were documented. 2 × 2 tables were formed and diagnostic accuracy of CT temporal bone was checked in terms of sensitivity, specificity, negative predictive value, and positive predictive value. The results revealed that CT temporal bone has a high diagnostic accuracy with a sensitivity of 92.5% and specificity of 100% for malleus (p value < 0.001). For incus and stapes, sensitivity came out to be 93.5% and 76% respectively and specificity values were 94.7% and 100% (p value < 0.001 for all) giving a verdict that the pre-operative use of this radiological investigation should be encouraged by otologists.

Trans-Nasal Endoscopic Repair of CSF Rhinorrhea: An Institutional Experience.

Introduction: Cerebrospinal Fluid (CSF) rhinorrhea results from breakdown in the integrity of structures separating the subarachnoid space and nasal cavity, namely subarachnoid space and dura mater, the bony skull base and periostea alongside the upper aerodigestive tract mucosa. Endoscopic repair is considered the treatment of choice for CSF rhinorrhea. Our aim of study was to analyze the etiopathogenesis and outcomes of treatment. Material and Methods: A retrospective study review of patients treated with endoscopic repair of CSF rhinorrhea at tertiary care hospital in ENT Department Benazir Bhutto hospital Rawalpindi from august 2013 to September 2017 identified 25 patients. Majority of them were male. The defects were closed in three layers using fat, fascia lata and nasal mucosa along with fibrin sealant in majority of patients. Pre operatively subarachnoid drain was placed in all patients. Patients were followed up to 3 months. Results: Forty-four patients underwent endoscopic repair of CSF rhinorrhea. The age group ranged from 16 to 55 years. Of the total of 44 patients 26 (59%) were males and 18(41%) females. The mean age of the patients in our study was 32.8 ± 9.7. Post trauma CSF leak was seen up to 52.3% of the patients. The most common site of leakage was identified Cribriform plate area. Our success rate of endoscopic repair was 88.6%. The most commonly observed complication was meningitis that was observed in 2 (4.5%) of the patients that too were managed conservatively. Conclusion: Accurate localization of site of leakage appears to be essential for successful endoscopic repair of CSF rhinorrhea. In our study cribriform plate area was commonly observed area of CSF leak. In our study, the success rate was 88.6% and low complication rate 4.5%.

Frequency of otitis media with effusion among children aged 1-5 years presenting to immunization center of tertiary care hospitals, Rawalpindi.

Objective: We conducted this study to assess the etiopathogenic relation of otitis media with effusion (OME) in a group of children aged 1-5 years among the local population of Rawalpindi. Methods: This was a cross-sectional retrospective study. Study was conducted among the children presenting to the immunization center of three tertiary care hospitals of Rawalpindi. Otitis media was assessed by clinical examination and tympanometry from August 2019 to January 2020. Multi-factor regression analysis was then applied to recognize the statistical significance and association of various risk factors to OME. Results: Out of 400 children enrolled in this study, 108 (27.0%) had OME, out of which 65 (60.2%) were males and 30 (27.8%) were of age group 2-3 years. Multivariable regression analysis of risk factors associated with OME showed it was strongly associated with snoring (P < 0.001), last year symptoms (attack of ear aches with hearing loss [P = 0.002]), drugs (URTI antibiotics [P = 0.026], All 3 drugs [P = 0.013]). Conclusions: We found out that OME is a common disease which if not identified or treated timely can lead to other hard to cure health problems. Control of its etiopathogenic factors can play a major role in its prevention.

Efficacy of Platelet Rich Fibrin in Myringoplasty.

OBJECTIVE: To determine the efficacy of usage of topical autologous platelet rich fibrin (PRF) in improving outcomes of myringoplasty regarding graft uptake and hearing improvement. METHODS: This study was conducted in the ENT department of Holy Family Hospital, Rawalpindi, over a period of six months from August 2019 to January 2020. It was designed as a prospective single blinded randomized controlled trial. The study involved a total of 50 participants in whom myringoplasty was done through post auricular approach using underlay technique. In 25 patients topical drops of PRF were used. Outcomes were compared after three months with the control group (n=25), who underwent myringoplasty without PRF. RESULTS: After three months follow-up, graft uptake was reported 78% and 52% in cases and controls, respectively (P=0.070). Mean hearing improvement was 18 dB and 6 dB in cases and controls, respectively (P=0.014). Postoperative infection occurred in 8% of the cases, and in 32% controls (P=0.037). CONCLUSION: Topical use of Platelet-Rich Fibrin during myringoplasty results in improved graft uptake. Hence, resulting in much improved hearing, significant reduction in infection rates and decrease in perforation sizes.
