“…CBCT has advantages such as shorter scanning times, lower costs, and a lower radiation dose (14). The CBCT technology allows scanning with the patient in an upright position (7). Sutthiprapaporn et al (10) evaluated RF depth in supine and upright positions using computed CT and CBCT.…”

Aim: This study aims to evaluate the radio-morphometry of important anatomical structures such as Rosenmüller fossa (RF), pharyngeal bursa (PB), and Eustachian tube (ET) in the posterior wall of the nasopharynx by cone beam computed tomography (CBCT). Material and Methods: The posterior wall of the nasopharynx was analyzed retrospectively in CBCT images of 110 patients. The depth and width of the Rosenmüller fossa (RF), pharyngeal bursa (PB), and Eustachian tube (ET), their distances to the posterior nasal spina (PNS) and mid-sagittal plane, and the angles between them were measured. RF was categorized into three types. The relationship between the measured values and gender, age groups, and RF types was investigated. The obtained variables were analyzed statistically. Results: The mean right RF depth was 8.2 and left RF was 8.6 mm. RF widths differed significantly by gender (right p=0.013, left p=0.004). There was a statistically significant positive correlation between RF-PNS distances and age (left r=0.314, p=0.001; right r=0.240, p=0.011). The prevalence of RF types was 31.8%, 19.5%, and 48.6% for type A, type B, and type C, respectively. In individuals with RF Type C, both RF and ET were located more lateral to the midline. The prevalence of PB was 45.5%. Conclusion: Nasopharyngeal carcinoma (NPC) most commonly occurs in the RF. A good knowledge of the anatomy and variations of the nasopharyngeal region is important in the early diagnosis of NPC. Oral and maxillofacial radiologists must know the anatomy of the nasopharynx to understand and interpret incidental findings in CBCT.

Aim: It was aimed to analyze the detailed morphometry of the pharyngeal recess (PR) using three-dimensional (3D) models reconstructed from multidetector computed tomography (MDCT). Material and Methods: This study was a retrospective analysis and performed on MDCT images of 97 patients (43 males, 54 females). 3D models of the PR were reconstructed using 3D Slicer software, enabling morphometric measurements according to established protocols. Measurements included PR depths, distances between the posterior nasal spine and torus levatorius (PNS-TL), distances between right and left TL (RTL-LTL) distances between the PNS and posterior wall of the nasopharynx (PNS-PWN), the angle (α) between the centerline of the PR and the sagittal plane. The morphologies of the PR classified into three types. Results: The average measurements for the parameters were as follows: PR depth - 10.42 mm, distance between PNS and TL - 10.40 mm, distance between RTL and LTL - 19.13 mm, distance between PNS and PWN - 19.92 mm, and the angle (α) - 53.65°. The prevalence of PR types were 20.62%, 47.42% and 31.96% for type 1, type 2 and type 3, respectively. Conclusion: Variations in reported measurements of the pharyngeal recess can be attributed to imaging techniques, patient positioning, anatomical differences, and sample sizes. The use of 3D models generated from MDCT datasets offers a high-resolution and comprehensive approach to understanding the PR's morphometry and spatial relationships, enabling accurate measurements and advancing our knowledge of this anatomical region.
