This study aims to assess how temporomandibular joint (TMJ) morphology is affected by unilateral maxillary sinus hypoplasia. Methods: For this study, cone beam computed tomography (CBCT) images in the radiology archive of the Department of Oral, Dental, and Maxillofacial Radiology, Faculty of Dentistry, & Idot;n & ouml;n & uuml; University, were retrospectively reviewed. The study included 77 patients (51 female, 26 male) aged 18-73 years with unilateral maxillary sinus hypoplasia. The patients' articular eminence angles, glenoid fossa root thickness, joint spaces, ramus lengths, condyle sizes, and condyle shapes were evaluated and compared bilaterally. Results: Condylar dimensions, joint spaces, articular eminence inclinations, glenoid fossa roof thickness, ramus length, and condyle shape did not significantly differ (p>0.05) between the hypoplastic and normal maxillary sinus sides. Conclusion: The study's findings show that maxillary sinus hypoplasia has no discernible impact on TMJ morphology; hence, this anatomical variation does not result in appreciable morphological alterations in the joint structure.eninfo:eu-repo/semantics/openAccesscone beam computed tomographymaxillary sinus hypoplasiatemporomandibular jointArticle10.58600/eurjther2896WOS:001655759700001Q30000-0003-2552-0187
