Anatomical Variations of the Paranasal Sinuses in Patients with Chronic Rhino Sinusitis Using Computerised Tomography Scan (CT) - A Review
نویسندگان
چکیده
Computerised tomography (CT) scan imaging techniques acts as a guide for functional endoscopic sinus surgery (FESS). It plays a vital role in the successful outcome of the treatment and management of the paranasal sinus variations. The frequent predisposing factors of chronic sinusitis are the anatomical variations of the paranasal sinus and nasal region. Computed tomography (CT) scan plays a fundamental role in the diagnosis of anatomical variations as well as of sinonasal diseases for a better guidance in the decision making about clinical, therapeutic and surgical approaches.

Introduction: Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate...
