Hyoid bone is a part of viscerocranium placed between the tongue root and thyroid cartilage to which it is connected by thyrohyoid membrane. Widely accepted morphological classification does not exist. Sexual dimorphism was analysed in this study and new guidelines for anatomical classification of hyoid bones based on anthropometric parameters were given. Total number of analysed bones was 70. ...

OBJECTIVE To detail the progress of a patient with TMJ dysfunction and headaches due to swimming, who underwent a conservative treatment plan featuring soft tissue therapy, spinal manipulative therapy, and rehabilitation. CLINICAL FEATURES The most important features were initial bilateral temporal headaches and persistent left sided TMJ pain brought about by bilateral breathing while swimmin...

Upper airway (UA) anatomical abnormalities are frequently observed in obstructive sleep apnea syndrome (OSAS). The correspondence between UA anatomical modifications and UA resistance (UAR) had not been studied. We aimed to determine if cephalometric characteristics could be related to segmental UAR. In twenty-five patients (21 males) (15 OSAS patients, 10 snorers) and 10 control subjects (8 ma...

The case is presented of an 8 1-year-old female coming to our observation after two non radical local excisions of a Merkel cell carcinoma of the sub-mental skin region. After a wide local excision, with en bloc elective bilateral neck dissection, simultaneous reconstruction with an infra-hyoid myocutaneous flap was performed. A brief overview concerning this rare tumour is presented and the su...

This study describes and compares two hyoid bones from the middle Pleistocene site of the Sima de los Huesos in the Sierra de Atapuerca (Spain). The Atapuerca SH hyoids are humanlike in both their morphology and dimensions, and they clearly differ from the hyoid bones of chimpanzees and Australopithecus afarensis. Their comparison with the Neandertal specimens Kebara 2 and SDR-034 makes it poss...

OBJECTIVE To review the outcomes of hyoid myotomy and suspension with a mandibular screw anchoring device. STUDY DESIGN Case series with chart review. SETTING Academic and private sleep surgery clinics. METHODS The study is a consecutive case series of patients undergoing hyoid myotomy and suspension using a mandibular screw suspension device as part of multilevel treatment of obstructive...

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 ...
