Study design: Observational Study
Abstract: 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.
