Morphometric Analysis of Arteria Lingualis for Transoral Tongue Base Surgery: A Study Based on MDCT Angiography

The base of the tongue is a difficult area to reach surgically. Although new surgical techniques make it easier to reach this area, there are some limitations. Knowing the anatomical details of the region plays an important role in overcoming these limitations. The LA is one of the most important neurovascular structures at the base of the tongue. Damage to this artery during surgery can cause problems that are difficult to reverse. In our study, we aimed to define the LA as a reliable landmark for transoral robotic surgery. The study was conducted on previously taken head CT images of 100 people (50 female and 50 male, age range 19–64). In our study, the parameters measured and recorded in the sagittal and axial plane. Those with a history of previous surgery in the region and images that could not be evaluated due to artifact were excluded from the study. In our study, two different parameters belonging to the LA were measured and their mean values were determined. The best approach for tongue base surgery should be the one that will both best control the examined area and minimize damage to surrounding vital structures. When literature information is evaluated, it is seen that new studies are important. Robotic surgery is an opportunity for patients in surgical interventions of an important region such as the tongue base. Radiological evaluation of the patient before surgical intervention is important to prevent possible errors. For this, sufficient morphological and morphometric information in the literature is required. We believe that the data we obtained will contribute to a better quality education for undergraduate students and radiology specialist students.
