In order to determine factors that may contribute to deglutition problems following supraglottic horizontal laryngectomy or its modified techniques, clinical records of 38 patients were studied. Contribution of the following factors was investigated: Age; sex; tumor classification; radical neck dissection; extent of and symmetry in removal of the aryepiglottic folds, arytenoid cartilages, and false folds; removal of the base of the tongue, hyoid bone, and a part of the vocal folds; extent of removal of the epiglottis and thyroid cartilage; cricopharyngeal myotomy; and some complications and concomitant diseases. The results suggest that removal of the arytenoid cartilage and asymmetrical removal of the false folds contribute to deglutition problems. We conclude that the standard supraglottic horizontal laryngectomy associated with surgical approximation of the larynx to the base of the tongue and cricopharyngeal myotomy does not usually cause serious deglutition problems. When the arytenoid cartilage is removed, reconstruction of the structure is required for the prevention of severe aspiration.

Hyoid suspension is a procedure to stabilise the retrolingual space in obstructive sleep apnoea. Using the Hörmann technique, a steel wire is slung around the body of the hyoid and fixed to the upper rim of the thyroid cartilage. It was observed, however, that the steel wire may lie very superficially to the pharyngeal mucosa. Evaluation of computed tomography (CT) scans showed a mean distance between the hyoid and the pharynx of only 3 mm. A modification is presented by threading a steel wire through a hole that is drilled through the hyoid bone. Thus pharyngeal exposure of the steel ligature and possible perforation of the mucosa is avoided.

Kerokan is a traditional Indonesian treatment involving abrading the skin over various parts of the body with a blunt object such as a coin or a piece of ginger which may create suspicious injuries. Here, the case of a 30-year-old woman who had undergone kerokan therapy is reported. She was complaining of retro-sternal pain and epigastric discomfort and subsequently became markedly short of breath and died. The observation of injuries predominantly located around the neck initiated a police investigation and forensic autopsy. Scattered abrasions, blisters and bruises were present on the forehead, the bridge of the nose extending to the ala, the upper and anterior aspect of the chin and the sternal notch, with discrete fresh and scabbed abrasions around the neck, over the sternum and on the backs of both hands. There were, however, no facial or conjunctival petechiae and no bruising of the underlying strap muscles, or fractures of the hyoid bone or thyroid cartilage. Histology revealed that myocarditis was the cause of death. Traditional practices may cause unusual bruises, abrasions, blisters and burns that may raise suspicion of inflicted injury from an assault. Knowledge of the manifestations of socio-ethnic practices such as kerokan is important in the evaluation of trauma in specific cultural groups.

A detailed understanding of muscle activity in human swallowing would provide insights into the complex neuromuscular coordination underlying swallowing. The purpose of this study was to introduce musculoskeletal analysis to investigate muscle activities involved in swallowing as there are limitations on studying comprehensive muscle activation patterns by conventional methods such as electromyography (EMG) measurement. A musculoskeletal model of swallowing was newly developed based on the skeletal model made from CT data of a healthy volunteer. Individual muscle forces were predicted in pharyngeal swallowing by inverse dynamics’ computations with static optimization, in which the typical trajectories of the hyoid bone and thyroid cartilage analyzed from videofluoroscopic (VF) data of the volunteer were used. The results identified the contribution of individual muscles in pharyngeal swallowing in relation to the movements of the hyoid bone and thyroid cartilage. The predicted sequence of muscle activity showed a qualitative agreement with salient features in previous studies with fine wire EMG measurements. This method, if validated further by imaging and EMG studies, enables studying a broader range of neuromuscular coordination in swallowing. The proposed method offers an avenue to understanding the physiological mechanisms of swallowing and could become useful to evaluate rehabilitation effects on dysphagia.
