Morphometric analysis of some important parameters for the transoral approach to the occipito-atlanto-axial region: MDCT study.

Context: Transoral approach is a frequently preferred method for the craniocervical region. Interventions in this area are performed for decompression purposes or to provide craniocervical fixation. To get a good result, knowing the anatomy of the region in detail will make the entrepreneur's job much easier.

Aims: The aim of the study is to contribute to the surgeons' perspective during the intervention by creating reference values in transoral approaches to the cervical region.

Settings and design: This study is a retrospective descriptive file screening study.

Methods: The study was performed using cranial computed tomography images of 200 patients. These patients consisted of 100 men and 100 women. The age range of the individuals included in the study varies between 20 and 80. In our study, the parameters measured and recorded in the coronal, sagittal, and axial plane.

Statistical analysis used: SPSS 22 was used for statistical analysis.

Results: In our study, seven different parameters were measured and recorded. Our results were evaluated between genders and in terms of lateralization. The obtained averages were tested statistically.

Conclusions: To plan and conclude a successful surgical intervention, it is necessary to have a good command of the area to be operated on. The data we present in our study will help surgeons dealing with the region in this sense. In addition, our study will contribute to the creation of a database on healthy individuals in Turkish society.
