Objective: In our study, it was aimed to determine whether there were differences in genial tubercle dimensions depending on age and gender.
Methods: In this study, 220 cone beam computed tomography (CBCT) images of patients (110 female and 110 male) between the ages of 20-80 years were obtained from the archive of İzmir Katip Çelebi University Faculty of Dentistry. All patients were divided into decade groups according to their age, and each decade group was divided into two subgroups according to gender. The genial tubercle was defined radiologically using axial, coronal and sagittal sections as well as 3D reconstruction image with NNT software program. Sagittal, vertical and horizontal dimensions of the genial tubercle were measured and statistically analyzed.
Results: There was a weak negative correlation between age groups and vertical values (r=-0.142; p=0.036) whereas the correlation coefficients between age groups and sagittal and horizontal values were not statistically significant (r=-0.043; p=0.530 and r=-0.039; p=0.563). There was a strong positive correlation between vertical and sagittal values in men (r=0.705, p<0.001) and women (r=0.714, p<0.001) in the whole group. There was a weak positive correlation between horizontal and sagittal, horizontal and vertical values in men (r=0.362, p<0.001; r=0.231, p<0.001) and women (r=0.304, p<0.001; r=0.257, p=0.007) in the whole group.
Conclusion: The vertical and horizontal dimensions of genial tubercle of men were higher than that of women. As the age of the patients increased, a decrease in the vertical values of the genial tubercle was observed.

Article Synopsis
- - The clinical report discusses a unique case of anatomical variations in the mandible of a 21-year-old male preparing for dental implants, highlighting unusual features of the mental foramen (MF) and mandibular canal (MC).
- - Notably, the patient had an atypical exit path for the MF and a distinct lingual groove leading to the MC, as well as enlarged and irregular genial tubercles (GTs).
- - The report underscores the necessity of advanced imaging techniques, like cone-beam computed tomography (CBCT), for effective dental implant planning and the importance of recognizing anatomical variations to avoid complications.
3D Genial Tubercle Anatomic Considerations in Genioglossus Advancement Surgery.

Article Synopsis
- The study aimed to examine how the shape of the genial tubercle varies and to measure its relationship with the genioglossus muscle using cadaver dissection techniques.
- Researchers analyzed 18 fresh cadaver heads, taking detailed 3D scans before and after muscle removal to obtain accurate measurements of the muscle attachments.
- Findings showed that the genial tubercle has variable morphology, with muscle attachment predominantly above the tubercle's peak, which may contribute to a high failure rate (39-78%) in surgical procedures intended to advance the genioglossus muscle.

Objectives: To identify pre-operative radiological parameters that are able to predict the functional outcomes of open partial horizontal laryngectomy (OPHL).
Methods: The present retrospective study concerned a cohort of 96 patients with laryngeal squamous cell carcinoma who underwent pre-operative radiological staging with contrast-enhanced computerised tomography of the neck, and subsequent supracricoid or supratracheal laryngectomy. Univariate and multivariate analyses were run to assess the prognostic value of the main demographic and surgical variables, and the pre-operative cephalometric values, respectively, in terms of predicting patients' functional outcomes.

Genioglossus advancement plays an important role in the armamentarium of the obstructive sleep apnea surgeon and has gone through many iterations over several decades. A recently described technique involves creating a box osteotomy, which is carried through the inferior border of the mandible in order to increase recruitment of the suprahyoid musculature. Here we introduce a further modification of the technique that uses virtual planning to improve the safety and accuracy of genial tubercle capture.
