Using the larynges of the newborn human and chimpanzee as models, Lieberman and Crelin ('71) and Lieberman, Crelin and Klatt ('72) have reconstructed the larynx of the "classic" Neanderthal La Chapelle aux Saints. The authors used their reconstructed vocal tract to generate linguistic functions which led them to conclude that Neanderthal lacked the ability to produce fully articulate human spee...

To capture and swallow food on land, a sticky tongue supported by the hyoid and gill arch skeleton has evolved in land vertebrates from aquatic ancestors that used mouth-cavity-expanding actions of the hyoid to suck food into the mouth. However, the evolutionary pathway bridging this drastic shift in feeding mechanism and associated hyoid motions remains unknown. Modern fish that feed on land m...

Objective: The present study was undertaken to compare the pharyngeal dimensions in Angle’s Class I normal and Angle’s Class II division 1 samples, and to correlate it with the dentoskeletal parameters in both the groups. Materials and methods: The sample consists of 92 pretreatment lateral cephalogram, which were categorized into two groups, Group A and Group B, that they should present Angle’...

Skeletal tuberculosis is a well-known disease entity. We report the first case involving hyoid bone and the use of polymerase chain reaction-based test in detection and management. A 62-year-old male presented with neck swelling of a 20-day duration along with change of voice and dysphagia. Examination revealed a cystic, osteolytic lesion of the hyoid bone which histopathologically demonstrated...

Mesenchymal chondrosarcoma is a rare tumor that is distinctly different from classic chondrosarcoma. The prognosis of this tumor is poor, with a high incidence of locoregional and distant metastases. It shows a predilection for the head and neck, however mesenchymal chondrosarcoma of hyoid bone has rarely been reported. We experienced a case of mesenchymal chondrosarcoma of the hyoid bone in a ...

Authors describe a hyoid bone body, without horns, attributed to Homo erectus from Castel di Guido (Rome, Italy), dated to about 400,000 years BP. The hyoid bone body shows the bar-shaped morphology characteristic of Homo, in contrast to the bulla-shaped body morphology of African apes and Australopithecus. Its measurements differ from those of the only known complete specimens from other extin...

This retrospective case series included five patients who underwent surgical resection of the cervical anterior osteophyte due to dysphagia. Videofluoroscopic swallowing studies (VFSSs) were performed before and after surgery on each patient, and kinematic analysis of the video clips from the VFSS of a 5-mL liquid barium swallow was carried out. Functional oral intake improved after surgery in ...

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...
