UNLABELLED Lymphangiomas are uncommon congenital hamartomas of the lymphatic system, usually diagnosed in infancy and early childhood. Commonly located at head and neck, they are rarely situated in the oral cavity. Preferred site of oral involvement is the tongue. In the absence of proper therapy, lymphangiomas of the tongue are extremely recurrent, leading to serious complications such as hemo...
In the assessment of the head and neck, differential diagnoses can be formulated by subdividing the anatomy into spaces along identifiable and logical boundaries. In the oral cavity, the root of the tongue is notably unlike adjacent regions due to structural and tissue-specific differences. The majority of lesions found in the root of the tongue are congenital and benign, representing ectopic t...
We use real-time magnetic resonance imaging (rtMRI) as a tool to investigate post-glossectomy speech by examining articulatory behavior. Our data reveal that listeners perceive speech produced by postoperative partial-glossectomy patients whose surgical procedure most affected the base of tongue to be typical, while speech produced by patients whose procedure affected the oral tongue is perceiv...
BACKGROUND Cervical nodal status is one of prognostic factors in head and neck squamous cell carcinoma (HNSCC). The objective of this study was to identify prognostic factors of cervical node status including site and size of primary tumors, presence of lymphovascular invasion, and size of cervical node for appropriate further treatment in HNSCC. METHODS A 5-year retrospective review of patie...
Transoral robotic surgery (TORS) offers a minimally invasive approach to resection of base-of-tongue tumors. However, precise localization of the surgical target and adjacent critical structures can be challenged by the highly deformed intraoperative setup. We propose a deformable registration method using intraoperative cone-beam computed tomography (CBCT) to accurately align preoperative CT o...
Conventional lateral radiography was used in 18 elderly male patients to investigate the changes induced by general anaesthesia in the upper airway. The effect of tongue traction under anaesthesia was studied similarly in another 11 patients. Following induction of anaesthesia, there were highly significant approximations to the posterior pharyngeal wall of the soft palate (median change 1.3 mm...
