Laryngectomy Surgery in India. Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy, the entire larynx is removed (including the vocal folds, hyoid bone, epiglottis, thyroid and cricoid cartilage and a few tracheal cartilagerings). In a partial laryngectomy, only a portion of the larynx is removed. Following the procedure, the person breathes through an opening in the neck known as a stoma. This procedure is usually performed by ENT surgeon in cases of laryngeal cancer, and an individual's quality of life can be affected post-surgery.
Biventricular pacemakers improve the symptoms of heart failure in about 50% of people that have been treated with medications but still have severe or moderately severe heart failure symptoms.
In addition, the heart failure patient may or may not need this type of pacemaker to treat slow heart rhythms and may or may not need an internal defibrillator (implantable cardioverter defibrillator, or ICD), which is designed to treat people at risk for sudden cardiac death or cardiac arrests.
