OBJECTIVE Using the Hörmann technique of hyoid suspension in sleep apnea surgery, a steel wire is placed through the thyroid cartilage and slung around the hyoid bone. However, we experienced thyroid cartilage fracture by steel wire traction. A modification is presented to avoid thyroid cartilage fracture. STUDY DESIGN Case series with chart review. SETTING University hospital. SUBJECTS A...

PURPOSE Long lasting usage of complete dentures causes lower occlusal vertical dimension, producing potential detrimental consequences. The aim of this study was to investigate how changes in vertical dimension during denture exchange affect muscular activity and hyoid bone position. MATERIAL AND METHODS Twenty-five edentulous, otherwise healthy patients (14 females, 11 males) aged 70.5 +/- 9...

Submandibular gland ptosis is a common impediment to obtaining superior surgical aesthetic results in neck lift surgery. Techniques for suspending the submandibular gland have been proposed, but these procedures have the drawbacks of disturbing the floor of the mouth mucosa and periosteum. We present an approach of submandibular gland suspension for the treatment of gland ptosis by employing a ...

PURPOSE To evaluate chewing and swallowing functions in women with and without temporomandibular disorder (TMD) and investigate the position of the mandible and the hyoid bone as they are important structures in the development of these functions. METHODS Seventy women were evaluated in relation to TMD diagnosis according to the Research Diagnostic Criteria, among them, 34 composed the study ...

BACKGROUND We identified the most useful variables for prediction of difficult laryngoscopy in patients with cervical spondylosis according to physical indicators and preoperative skeletal X-ray and soft tissue MRI measurements. We hypothesized that there was a closer association between difficult laryngoscopy and radiologic indicators. METHODS We randomly enroled 315 patients undergoing elec...

OBJECTIVE To determine if there is an indicator on the lateral cephalometric radiograph that can be used for the differential diagnosis of severe obstruct sleep apnea syndrome and simple snoring in nonobese young male adults. MATERIALS AND METHODS The subjects were Taiwanese male patients with a complaint of snoring and/or sleep apnea, whose body mass index was less than 25 kg/m(2) and who we...

Study Design A descriptive experimental study. Purpose The purpose of this study was to describe the reliability and accuracy of palpable anterior neck landmarks (angle of the mandible, hyoid bone, thyroid cartilage, and cricoid cartilage) for the identification of cervical spinal levels in a slight neck-extended position as in anterior approach cervical spinal surgery. Overview of Literatu...

Reports of infrahyoid muscle variations abound in the literature. Specifically, anatomical reports mentioning the cleidohyoideus accessorius muscle date back to the 19th century. Several authors have attempted to classify the anatomical variation that constitutes a muscle inserting from the clavicle into the hyoid bone in the presence of an intact omohyoid. In 1897 Le Double described variation...

INTRODUCTION Advancement genioplasty has been increasingly indicated for the correction of anterior mandibular deficiency as it balances the patient's profile and generates functional changes. OBJECTIVE Thus, the aim of this study was to assess the effects of advancement genioplasty in the oropharyngeal size and in the position of the hyoid bone and tongue. METHODS The sample comprised 22 l...

Thyroglossal duct cysts are one of the most common cervical congenital anomalies. They occur along thyroid migration tract, which extends from base tongue through midline neck to level cricoid cartilage. present as a mass and closely associated with hyoid bone. Here, we describe case where two cystic structures were found just inferior gland bone, suggesting double thyroglossal cyst. It is impo...
