The anatomical structure of the ostiomeatal complex (OMC) plays a crucial role in the success of dental implantation procedures, particularly in the maxillary region. This study examines the anatomical variations of the OMC and their impact on postoperative complications in dental implantation. A total of 400 spiral computed tomography (CT) scans of patients aged 18 to 95 years were analyzed to assess key anatomical structures, including the maxillary sinus, concha bullosa, uncinate processes, and sinus ostium dimensions. Findings revealed significant anatomical variability, with concha bullosa observed in 33.2% of cases, uncinate process variations in 31.6%, and a narrowed maxillary sinus ostium in 6.25% of cases. These structural differences were found to influence sinus ventilation and drainage, thereby increasing the risk of postoperative complications such as sinusitis and impaired osseointegration. Statistical analysis highlighted strong correlations between sinus volume, bone thickness, and OMC components, reinforcing the need for thorough preoperative assessment. The study underscores the importance of personalized surgical planning and advanced imaging techniques in mitigating complications and optimizing dental implantation outcomes
Anatomy of the maxillary sinus: implications for odontogenic sinusitis development
(2024) Gorbik, E.; Ohurtsov, O.; Heranin, S.; Kolba, O.; Breslavets, N.; Sazonova, O.; Kysylenko, K.; Alekseeva, V.
This study investigates the anatomical prerequisites that could contribute to the development of this condition. Material and methods: Using multi-slice computed tomography (MSCT), the study examined the structure and relationships of key anatomical features, including the alveolar process, sinus wall thickness, and the position of the teeth in relation to the maxillary sinus. The results revealed that the lower wall of the maxillary sinus is predominantly formed by the alveolar process, with significant variability in wall thickness, especially between the central and lateral regions. In 95% of cases, this wall was closely associated with the roots of the upper teeth, particularly the premolars. A strong negative correlation was observed between the thickness of the alveolar process and the volume of the maxillary sinus, suggesting that larger sinuses tend to have thinner alveolar processes. Additionally, a significant correlation was found between the position of the sinus and the degree of pneumatization, with a more medially positioned orbit in cases of reduced pneumatization.Conclusion: Structural features of the maxillary sinus, such as its proximity to the teeth and its relationship to sinus pneumatization, are critical factors in the development of odontogenic rhinosinusitis. A comprehensive, collaborative approach is necessary for effective management and prevention, with careful consideration of these anatomical aspects during dental and maxillofacial interventions
