CBCT Segmentation

The purpose of this retrospective observational study is to investigate whether mandibular canal dimensions and sublingual fossa morphology can serve as radiographic predictors of the mandibular lateral lingual canal (MLLC) using cone-beam computed tomography (CBCT). CBCT images of adults with unilateral MLLC will be retrospectively evaluated. Mandibular canal diameter, mental foramen diameter, and sublingual fossa depth will be compared between the side with the MLLC and the contralateral side. In addition, the location, diameter, and course of the MLLC will be analyzed to identify radiographic features associated with its presence and to improve preoperative assessment for mandibular surgical procedures.

regulate nasal airflow, humidify and filter inspired air. Serrated inferior turbinate is a rare anatomical variation characterized by an irregular, serrated appearance of the inferior turbinate bone. Although this variation has been described in radiological studies, its possible relationship with maxillary sinus mucosal changes and other sinonasal anatomical features remains unclear. This retrospective observational study aims to evaluate the relationship between serrated inferior turbinate variation and maxillary sinus mucosal thickness, mucosal abnormalities, and other sinonasal anatomical structures using cone-beam computed tomography (CBCT) images. CBCT images obtained from patients who underwent imaging for routine diagnostic purposes will be retrospectively reviewed. The presence of serrated inferior turbinate variation, maxillary sinus findings, inferior turbinate measurements, and nasal septum characteristics will be evaluated. The study aims to improve understanding of the radiological significance of serrated inferior turbinate variation and to provide information that may contribute to more accurate evaluation and reporting of sinonasal anatomical variations.
