The prognosis is affected by the location of the tumour. For the purposes of staging, the larynx is divided into three anatomical regions: the glottis (true vocal cords, anterior and posterior commissures); the supraglottis (epiglottis, arytenoids and aryepiglottic folds, and false cords); and the subglottis. Most laryngeal cancers originate in ...
Larry Page, the founder of Google, described his difficulties with vocal nerve injury and has been a supporter of Zeitels and the Voice Health Institute. [ 7 ] [ 8 ] [ 9 ] Zeitels conceived and directs the Voice Restoration Research Program, which is a collaborative effort of investigators at Harvard and MGH, as well as Robert Langer at MIT .
Hypopharyngeal cancer is a disease in which malignant cells grow in the hypopharynx (also known as the laryngopharynx) the area where the larynx and esophagus meet. [1] It first forms in the outer layer of the hypopharynx (last part of the pharynx), which is split into three areas. Progression of the disease is defined by the spread of cancer ...
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box (), throat (nasopharyngeal, oropharyngeal, [1] hypopharyngeal), salivary glands, nose and sinuses.
Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds. [1] Although diagnosis involves a physical examination of the head and neck , as well as perceptual voice measures, visualization of the vocal nodules via laryngeal endoscopy remains the primary diagnostic method.
A common symptom of laryngeal papillomatosis is a change in voice quality. More specifically, hoarseness is observed. [4] [5] As a consequence of the narrowing of the laryngeal or tracheal parts of the airway, shortness of breath, chronic cough and stridor (i.e. noisy breathing which can sound like a whistle or a snore), can be present.
The International Classification of Diseases for Oncology (ICD-O) system lists a number of morphological subtypes and variants of malignant squamous-cell neoplasms, including: [22] papillary thyroid carcinoma (code 8050/3) verrucous squamous-cell carcinoma (code 8051/3) papillary squamous-cell carcinoma (code 8052/3) squamous-cell carcinoma ...
The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]
