Objective: To evaluate the effect of using the tongue-out position on the quality of the anatomical appearance of the pharynx on computed tomography (CT) images.Methods: The data from enhanced CT thin-section images of the head and neck in 119 cases scanned were retrospectively analyzed. The cases were divided into two groups based on the position of the tip of the tongue on the images: the tongue-out group (63 cases) and non-tongue-out group (56 cases). Two observers separately evaluated the anatomy of the soft palate, uvula, palatine tonsils, epiglottis, epiglottic fossa, pyriform fossa, arytenoid folds, and tongue on all images. The Kappa test was applied to assess the consistency of scores between the two observers. In the case of data that satisfied the normal distribution, the significance of the difference in the average scores between the two groups was tested using an independent samples t-test with a value of p > 0.05. In the case of data that did not satisfy the normal distribution, the Mann–Whitney U test was adopted to test the significance of the difference in the average scores between the two groups using a value of p < 0.05. The number of cases with swallowing artifacts on the CT images in both groups was statistically analyzed and the chi-square test was used to determine whether the difference in the incidence of artifacts between the two groups was significant.Results: The Kappa test showed good consistency between the two observers scoring of the soft palate, uvula, epiglottis, epiglottic fossa, pyriform fossa, aryepiglottic folds, and tongue. The image scores of the soft palate, uvula, epiglottis, epiglottic fossa, and tongue in the tongue-out group vs. the non-tongue-out group did not satisfy the normal distribution. The Mann–Whitney U test showed that the differences in the image scores between the two groups were statistically significant in all cases (p < 0.05). The incidence of swallowing artifacts in the tongue-out group and the non-tongue-out group was 15 and 32%, respectively. The result of the chi-square test showed that the difference in the incidence of swallowing artifacts between the two groups was statistically significant (p = 0.037).Conclusion: The tongue-out position facilitated an improvement in the CT appearance of pharyngeal anatomy and was associated with a reduction in the incidence of swallowing artifacts.

INTRODUCTION: The neurofibroma is a nonmalignant new growth of neuroectodermal origin. neurofibromas appear at the end of a nerve, often in the skin, producing small nonencapsulated nodules which may have pigmentation in the overlying skin. Neurofibromatosis with laryngeal involvement presents with dyspnea, followed by hoarseness, stridor, dysphagia, and voice change. most common sites involved in the larynx are the arytenoids and the aryepiglottic folds. CASE REPORT: 65-year-old female with previously diagnosed of neurofibromatosis since 10 years of age manifested by multiple cutaneous nodules The patient had symptoms of dysphagia, hoarseness of voice for past 2 months. Direct laryngeal examination using flexible endoscope showed a edematousulceroproliferative growth in the laryngeal surface of epiglottis and fullness in the left pyriform fossa. Hisopathological examination revealed squamous cell carcinoma from epiglottis and fibromatosis changes from pyriform fossa. CONCLUSION: All neurofibromatosis patient and their family members should under go regular oral and laryngeal examination to rule out complications at the earliest.
