  Magnetic resonance imaging of Rosenmüller Fossa morphology in nasopharyngeal carcinoma

  Medişoğlu, M.Sabri; Öçbe, Melisa

  The Rosenmüller Fossa (RF) is the most common site of origin for nasopharyngeal carcinoma (NPC); however, its morphometric characteristics remain underinvestigated in clinical imaging studies. This study aimed to evaluate the morphological and dimensional differences in the RF between patients with NPC and healthy controls using magnetic resonance imaging (MRI). A retrospective analysis of MRI data from 41 patients with NPC and 49 age- and sex-matched controls without nasopharyngeal pathology was performed. Measurements included RF height, width, inter-fossa distance, and nasopharyngeal depth on axial and sagittal MR images. RF morphology was classified as Type A (shallow), Type B (deep and narrow), or Type C (deep and wide). The mean age of patients with NPC was 51.22 ± 13.81 years, and 68.29% were men. Tumor laterality was bilateral in 56.10% of the cases, and RF involvement was observed in 70.73% of the cases. No significant differences were found in right RF dimensions or R-L distance (p>0.05); however, left RF height was significantly reduced in patients with NPC (3.49 vs. 5.42 mm; p=0.013). Nasopharyngeal depth was also shorter in patients with NPC (17.40 mm vs. 19.03 mm; p=0.006). The RF morphology distribution did not differ significantly (p=0.381), although Type C fossae were more common in patients with NPC (26.83% vs. 14.29%). MRI revealed significant reductions in the left RF height and nasopharyngeal depth in patients with NPC, suggesting asymmetrical nasopharyngeal involvement. Detailed RF assessment using MRI may contribute to the early detection and improved staging of NPC.

  Quantitative assessment of uvula dimensions, airway space, and pharyngeal bursa in children with and without adenoid hypertrophy

  Öçbe, Melisa; Gözüyukarı, Hilal; Akçay, Hülya

  This study aimed to investigate the association between adenoid hypertrophy (AH) and upper airway morphology in pediatric patients, with a specific focus on uvula dimensions, pharyngeal bursa characteristics, and nasopharyngeal airway space using sagittal and axial magnetic resonance imaging (MRI). In this retrospective cross-sectional study, MRI scans of 104 pediatric patients aged 1–18 years were analyzed. Uvula height and width, pharyngeal bursa height and width, and the nasopharyngeal airway distance (from the posterior nasal spine to the posterior pharyngeal wall) were measured using calibrated DICOM software. Patients were grouped based on the presence of AH, and anatomical measurements were compared accordingly. Correlations with age and sex were also assessed. Statistical analysis included t-tests, ANOVA, chi-square tests, and Pearson correlation. Children with AH had significantly reduced nasopharyngeal airway space compared to those without AH (mean: 12.05 mm vs. 16.71 mm, p<0.001). No significant differences were observed in uvula or bursa dimensions across groups. A strong correlation was found between uvula height and width (r=0.66), and both increased significantly with age. Males showed greater pharyngeal bursa height than females (p=0.001), while bursa width did not differ significantly by sex. MRI is a valuable non-invasive tool for evaluating pediatric airway anatomy. While AH is associated with airway narrowing, it does not appear to affect uvula or bursa characteristics. Pediatric dentists should consider comprehensive airway assessments, as early detection of obstruction can impact craniofacial development and treatment planning.
