OBJECTIVE To assess the position and movements of the hyoid bone during deglutition in patients with open bite. METHODS Thirty-six subjects were divided into 2 groups according to the presence of anterior open bite. The open bite group (OBG) and control group each comprised 18 patients with a mean overbite of -4.9 ± 1.9 mm and 1.9 ± 0.7 mm. The position of the hyoid bone during the 4 stages o...

Introduction: This study aims to evaluate the parameters that might have an impact on swallowing performance after a total glossectomy with laryngeal preservation (TGLP). Methods: Among 39 patients who underwent surgery with curative intent for squamous cell carcinoma of the tongue, our retrospective analysis focused on 18 patients treated by TGLP and flap reconstruction. The flap was position...

The Videofluoroscopic Swallowing Study is a technique commonly used by radiologists to detect abnormalities in the swallowing process. While the subject swallows the food, X-ray images are taken and then compiled in a video form. The video is later analyzed by the radiologist using visual means. Since the nature of the inspection is highly subjective, the result of the inspection can barely be ...

OBJECTIVE To investigate effects of tracheostomy tube on the movement of the hyoid bone and larynx during swallowing by quantitative analysis of videofluoroscopic swallowing study. METHOD 19 adult stroke patients with tracheostomies, who met the criteria of decannulation participated. Serial videofluroscopic swallowing studies were done over 14 days before decannulation, within 24 hours befor...

OBJECTIVE Fractures of the hyoid bone are rare occurrences. They are mainly caused by strangulation/asphyxiation injuries, trauma to the neck, and motor vehicle accidents (MVAs). As a result of their rarity, proper treatment guidelines are not in place for dealing with these injuries. In this study, a systematic literature review was conducted with the goal of identifying optimal management for...

In the conventional supracricoid laryngectomy technique, tumors extending beyond the lingual surface of the epiglottis with tongue base invasion are contraindicated due to the requirement of the hyoid bone resection. The loss of the hyoid bone causes intractable aspiration and renders the cricoidal pexy process impossible. Therefore, surgeons tend to treat such tumors with total or subtotal lar...

Purpose This study was aimed to examine the effectiveness of a high-speed jaw-opening exercise, which targets the contraction of fast-twitch muscle fibers, in improving swallowing function. Subjects and methods Twenty-one subjects (mean age 74.0±5.7 years) with dysphagia-related symptoms, such as coughing or choking during eating, performed the exercise. None of the included subjects had neur...

We studied radiographically 11 patients in whom direct laryngoscopy proved difficult and 100 control (general population) subjects. The vertical distance between the mandible and the hyoid bone (mandibulohyoid distance) was measured and the positions of the mandibular angle and hyoid bone determined in relation to the cervical vertebrae. We found that the mandibulohyoid distance was substantial...

OBJECTIVE To describe a method of hyoid cartilage division during Sistrunk operation for management of thyroglossal duct cyst (TGDC) and compare postoperative outcomes with those of conventional hyoid bone cutting. METHODS Fifty-nine patients who received operative treatment for TGDC from January 2005 to July 2013 were enrolled. The degree of fusion in the cartilaginous portion of the hyoid w...
