VOCAL CORD POLYP

VOCAL CORD POLYP
This picture depicts a polyp of one vocal cord with normal opposite cord. Injury or chronic irritation causes changes in the vocal cords that can lead to polyps or nodules. The main cause is chronic voice abuse (yelling, shouting, singing loudly, or using an unnaturally low frequency). Polyps may have several other causes, including gastric reflux, untreated hypothyroid states, chronic laryngeal allergic reactions, or chronic inhalation of irritants, such as industrial fumes or cigarette smoke. Polyps may occur at the mid third of the membranous cords and are more often unilateral. Symptoms are hoarseness and a breathy voice.If these symptom persists for more than three weeks, visualization of the vocal cords with a mirror or camera is a must. Diagnosis is based on biopsy to rule out cancer. Surgical removal with the help of an operating microscope restores the voice,but removal of the irritating source is essential to prevent recurrence. Correction of the underlying voice abuse cures most nodules and prevents recurrence. Removal of the offending irritants allows healing, and voice therapy with a speech therapist reduces the trauma to the vocal cords from improper singing or protracted loud speaking. In microlaryngoscopy, an operating microscope is used to examine, biopsy, and operate on the larynx. Images can be recorded on video as well. The patient is anesthetized, and the airway is secured.The microscope allows observation with magnification.Tissue can be removed precisely and accurately, minimizing damage to the vocal mechanism. Laser surgery can be done through the optical system of the microscope to allow for precise cuts.
