INTRODUCTION: Sir Charles Bell is renowned and revered as an outstanding surgeon, anatomist, clinician and teacher and his many contributions to various medical fields have been amply described. What are less well-known are his contributions to the field of laryngology. METHODS: Selected clinical and physiological publications by Bell were examined that addressed issues related specifically to the airway or pharynx. These included both case reports and case series...

The trachea has a complex anatomy to fulfill its tasks. Its unique fibro-cartilaginous structure maintains an open conduit during respiration, and provides vertical elasticity for deglutition, mobility of the neck and speech. Blood vessels pierce the intercartilaginous ligaments to perfuse the ciliated epithelium, which ensures effective mucociliary clearance. Removal of a tracheal segment affected by benign or malignant disease requires airtight restoration of the continuity of the tube. When direct approximation of both tracheal ends is no longer feasible, a reconstruction is needed...

With the progress of multidisciplinary vascular anomaly treatment, the use of radiotherapy, cryotherapy, laser therapy and medical treatments, the corticosteroid, sclerotherapy, and many more, the role of surgery has been refined. Surgical treatment has historically been the mainstay of treatment and will maintain.A miniature tourniquet technique applied to the tongue was successfully utilized in reducing bleeding to a minimum during surgical resection of a massive cavernous hemangioma involving the tongue and lower lip without any postoperative complications...

Surgical manipulation of the sensory and motor nerves of the rat tongue is often employed in studies evaluating the oral cavity functions of mastication and deglutition. A noninvasive, atraumatic approach that will then facilitate sufficient manipulation of these structures is required. In this study, we detail an approach that consistently allows identification of the hypoglossal (motor) and lingual (sensory) nerves of the rat. Six Wistar rats (250-500 g) were anesthetized and dissected either as fresh tissue (N = 3) or following transcardial perfusion with 4% paraformaldehyde (N = 3)...

Patients with multiple fractures involving upper third of the face, the mid-face and the lower third are generally referred to as Pan-facial fractures and managing these cases is extremely complicated. Proximity of the maxillofacial region to the important features or senses such as visual function (diplopia), olfaction, respiration (airway management), chewing or mastication (occlusion), deglutition and aesthetics; makes the scenario a little more complex for the surgeon operating in this particular region than the surgeon operating any other part of the body...

Lesions of the lower cranial nerves (LCN) are due to numerous causes, which need to be differentiated to optimize management and outcome. This review aims at summarizing and discussing diseases affecting LCN. Review of publications dealing with disorders of the LCN in humans. Affection of multiple LCN is much more frequent than the affection of a single LCN. LCN may be affected solely or together with more proximal cranial nerves, with central nervous system disease, or with nonneurological disorders. LCN lesions have to be suspected if there are typical symptoms or signs attributable to a LCN...

This study describes the morphology of the laryngeal apparatus in bowhead whales (Balaena mysticetus) with respect to respiration, deglutition, and vocalization. We also examined the intrinsic cricoarytenothyroid muscle (Musculus (M.) diverticuli laryngei) which forms the laryngeal diverticulum, to ascertain its interactions with the laryngeal cartilages during respiration and sound production. Five fetal larynges and four from adult whales were studied using noninvasive imaging, as well as macroscopic and microscopic techniques...

Head and neck cancer is a unique cause of dysphagia. Altered swallow function can be secondary to the mechanical effects of a tumor invading normal anatomy needed for deglutition, or as a direct sequela of cancer treatment (surgery and/or radiation ± chemotherapy). This article outlines the incidence of head and neck cancer, effects of anatomic changes associated with common surgical intervention, and the consequences of treatment-induced dysphagia. Assessment and rehabilitation techniques applicable for this population are discussed...

Abstract The main purpose of palatoplasty is to establish normal speech and deglutition. To enhance the chance of successful palatal repair, as well as optimal velopharyngeal competence, the anatomy of the palate has to be thoroughly understood. While carrying out the repair, some surgeons prefer to cut the tensor veli palatini (TVP) tendon, others perform a tenopexy or fracture the hamulus around which the tendon passes, to facilitate mobilisation of palatal tissue. However, the exact anatomy and function of the TVP is still controversial and severing the tendon or its path could be of potential harm...

Valuable information is available to clinicians both from research articles, and reports from clinicians. Both sources have limitations. Research, with the exception of longitudinal studies, tends to isolate a variable or two from the whole, limiting its usefulness. Clinical techniques reported are sometimes biased, and perform well for certain therapists in certain settings, and not so well for others. Interrelationships are important among variables such as dentition, anatomy, physiology, oral muscle functions, oral rest postures, eating, and speech...

OBJECTIVE: The surgical treatment of cancer of tongue results in speech deficits. Speech disorders in the glossectomised patients fall into, categories of impaired articulation, reduced speech intelligibility, altered oral & nasal resonance, impaired voice quality & reductions in global speech proficiency. Since speech is a social tool, its most significant measurements start with the degree to which it can be understood. METHODS: This study was conducted at Tata Memorial Hospital, Mumbai, India, An incidental sample of 25 patients was selected for this study...

CONTEXT AND OBJECTIVE: Although there is a close relationship between swallowing and breathing, there are no studies evaluating the radiographic anatomy of the airway and its possible correlation with the radiographic position of the hyoid bone. The aim of this study was to evaluate the possible correlation of the radiographic position of the hyoid bone and airway space (PAS) in lateral radiographs on children with atypical deglutition, in comparison with those with normal swallowing...

Consequences of dysphagia substantially reduce quality of life, increase the risk of medical complications and mortality, and pose a substantial cost to healthcare systems. As a result, it is of no wonder that the clinical and scientific communities are showing interest in new avenues for dysphagia rehabilitation. Electrical stimulation (e-stim) for the treatment of swallowing impairments is among the most studied swallowing interventions in the published literature, yet many unanswered questions about its efficacy remain...

Cranial neuropathies are frequent and their semiological analysis is the basis of the diagnostic workup. This is even more true in the case of multiple cranial neuropathies. We here propose a diagnostic exercise in the case of a simultaneous cranial nerves IX (glossopharyngeal), X (vagus) and XI (spinal) deficit. This case exemplifies that knowledge of nervous anatomy and physiology is the basis of the semiology of the nervous system.

Tracheotomies are increasingly performed in the pediatric population in the context of long-term treatment. There are specific pediatric aspects that require attention: differences in the pediatric compared to adult anatomy, the necessity for later reconstruction and the negative impact on oral feeding and speech development. Caring for pediatric tracheostomy patients is more challenging compared to adult patients. This needs to be addressed by a dedicated team during both in- and outpatient treatment.

Recently, the importance of deglutition has attracted attention due to its role in the prevention of aspiration pneumonia. We therefore observed the anatomy of the pharynx of 57 hemi-sections of adult Japanese cadavers (male 32 sides, female 25 sides). A previously unidentified tissue was observed in the infratemporal fossa. This unidentified tissue was a thin membranous tissue that existed between the medial pterygoid and the superior constrictor in all of the cadavers examined. The previously unknown membranous tissue consisted of collagenous and muscular fibers and was innervated mainly by a branch of the mandibular nerve...

Isomerism or Heterotaxy syndromes are rare multifaceted congenital anomalies with multi-system involvement. Grouped under the broad category of Situs Ambiguous defects, these often pose diagnostic difficulties due to their varied and confusing anatomy. Since patients rarely survive into adulthood due to cardiovascular complications, the etiology and natural history of such conditions are not fully understood. Imaging provides the most accurate non invasive method for diagnosis and thereby, prognosis in such cases...

This study aimed to apply novel high-resolution manometry with eight-sector radial pressure resolution (3D-HRM technology) to resolve the deglutitive pressure morphology at the esophagogastric junction (EGJ) before, during, and after bolus transit. A hybrid HRM assembly, including a 9-cm-long 3D-HRM array, was used to record EGJ pressure morphology in 15 normal subjects. Concurrent videofluoroscopy was used to relate bolus movement to pressure morphology and EGJ anatomy, aided by an endoclip marking the squamocolumnar junction (SCJ)...
