CBCT Imaging Assessment of Sinonasal Variations and Pathologies in Rhinoplasty Candidates a Cross-Sectional Study

Area of Science:

• Otolaryngology
• Plastic Surgery
• Radiology

Background:

• Preoperative assessment of sinonasal anatomy is crucial for rhinoplasty success.
• Cone-beam computed tomography (CBCT) provides detailed imaging of sinonasal structures.

Purpose of the Study:

• To evaluate the utility of CBCT in identifying sinonasal anatomical variations and pathologies in rhinoplasty candidates.
• To assess the prevalence of specific sinonasal variations and their association with demographic factors.

Main Methods:

• A cross-sectional study involving 156 rhinoplasty candidates (90 males, 66 females; mean age 34.2 years).
• CBCT scans were analyzed to assess maxillary, ethmoid, and frontal sinuses, and nasal septal deviation (mild, moderate, severe).
• Chi-square tests were used to determine associations with age and gender (p < 0.05).

Main Results:

• Nasal septal deviation was highly prevalent (83.6%), with moderate and severe forms most common.
• Maxillary sinus pathology (44.9%, mainly mucosal thickening) and supraorbital cells (55.8%) were frequently observed.
• Significant associations were found between age and maxillary sinus pathology, nasal cavity pathology, and frontal sinus size; supraorbital cells correlated with age and gender.

Conclusions:

• CBCT is effective for identifying sinonasal variations and pathologies in rhinoplasty candidates.
• High prevalence of septal deviation and maxillary sinus pathology highlights the importance of preoperative imaging.
• Demographic associations with sinonasal variations can inform personalized surgical planning for better outcomes.
