Publication Anterior Cruciate Ligament Tear Using Magnetic Resonance Imaging among Patients Undergoing Arthroscopy in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2023) Shrestha, Rohit; Khadka, Sushant Kumar; Chaudhary, Aashutosh; Acharya, Shreedhar Prasad; Malla, Manasil; Gautam, Prabesh; Maharjan, Sagar; Basi, Ashkal; Thapa, Sangharsha; Karki, SubindraAbstract Introduction: Magnetic Resonance Imaging is the preferred imaging modality in patients having anterior cruciate ligament tears. The aim of this study was to find out the prevalence of anterior cruciate ligament tears using magnetic resonance imaging among patients undergoing arthroscopy in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted in the Department of Orthopaedics and Traumatology of a tertiary care centre. Data from 17 November 2017 to 17 October 2022 were collected between 26 December 2022 and 30 December 2022 from the hospital records. Ethical approval was obtained from Institutinal Review Committee of the same institute (Reference number: 233/22). All patients with a knee injury who received arthroscopy were included in the study. Magnetic resonance imaging reports, arthroscopic findings and relevant data of each case were retrieved from the medical case records of patients. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among patients with arthroscopy confirmed anterior cruciate ligament tear, 138 (91.39%) (86.92 to 95.86, 95% Confidence Interval) had anterior cruciate ligament tear diagnosed with magnetic resonance imaging. The mean age of the patients who had anterior cruciate ligament tear in the magnetic resonance imaging was 32.35±11.31 years. Out of them, 87 (63%) were males and 51 (37%) were females. The mean duration of the injury was 11.60±18.47 months. Conclusions: The prevalence of anterior cruciate ligament tear using magnetic resonance imaging among patients undergoing arthroscopy in tertiary care centres was similar when compared to other similar studies when conducted in similar settings.Publication Computerized Tomography-Based Volumetric Analysis Of The Maxillary, Sphenoid, And Frontal Sinuses: An Observational Study(Nepal Medical Association, 2025) Dhakal, Ashish; Shrestha, Bikash Lal; Pokharel, Monika; Shrestha, Samip; Karki, Subindra; Shrestha, Krishna SundarAbstract Introduction: Volumetric analysis of the paranasal sinuses can help evaluate disease extent, treatment, and sinus surgery outcome. This study aims to determine the baseline volumes of frontal, maxillary, and sphenoid sinuses. Methods: An observational cross-sectional study was conducted in a tertiary care center after obtaining ethical approval (Reference number: 264/2021). Computerized Tomography Scan head or Computerized Tomography Scan nose/Paranasal sinus images of patients across all age groups from January to December 2022 were analyzed. Sinus volumes were calculated using Digital Imaging and Communications in Medicine software. Results: The study included 154 patients, median age was 29 years (IQR: 22.75 - 39.25) and 84 (54.5%) were male. The median volume of the maxillary sinus was 14.30 cm³ (IQR: 10.76 - 18.02), with the right side at 13.82 cm³ (IQR: 10.34 - 17.39) and the left at 14.62 cm³ (IQR:11.11 - 18.75). The median volume of the sphenoid sinus was 4.52 cm³ (IQR:3.02 - 6.03), with the right side at 4.42 cm³ (IQR: 2.61 - 6.84) and the left at 3.95 cm³ (IQR: 2.16 - 6.47). The median volume of the frontal sinus was 2.59 cm³ (IQR:1.42 - 4.59), with the right side at 2.27 cm³ (IQR:0.94 - 4.12) and the left at 3.04 cm³ (IQR:1.22 - 5.04). Conclusions: Male population had larger volumes across all types. The maxillary and frontal sinuses had the largest and smallest volumes respectively.
