Investigating Anatomical Variations in Paranasal Sinuses: A Comprehensive Analysis through Retrospective CT among the Indigenous Population at Multi - Speciality Hospital, Shillong

Hulda Dkhar, Pynhunlin Lyngdoh, Wilson Hrangkhawl

Abstract: Introduction: The anatomy of the nasal cavity and paranasal sinuses is one of the most frequently diverse in the human body. ( (Papadopoulou et al., 2021) . Deviations in the pneumatization of ethmoid sinuses can effect sinus ventilation and drainage pathways, probably serving as etiological factors for sinusitis and the spread of infection to adjacent structures. (Qureshi & Usmani, 2020). The Anatomical variations can occur due to race, environmental adaptation, geographical region, and exposure to chemicals or radiation. (Alraddadi, 2021) It is critical to evaluate these anatomic differences of the paranasal sinuses. (Akbar Ali etal., 2022) Anatomic variation knowledge proves crucial for sinus surgeons as it minimizes surgical complication rates during Functional Endoscopic Sinus Surgery (FESS), describes illness recurrence, and enables one to modify operative approach. (Tbassum, 2017) Different types of imaging modalities are available for evaluation of paranasal sinuses. While Conventional radiography provides useful information in the diseases of maxillary and frontal sinuses however, it has some limitation role in evaluation of nasal cavity, ethmoid and sphenoid sinuses. Conventional radiography does not show osteomeatal complexes. Multi detector computed tomography (MDCT) offer the details of a bony, soft tissue and air in the paranasal sinuses and accurate outline of the anatomy, and the anatomical variants and the extent of the pathology in and around the paranasal sinuses. The preferred method for examining the paranasal sinuses and nearby structures at the moment is Computed Tomography. (Lingaiah et al., 2016)
