Abstract BVFP is an uncommon condition with potentially significant negative effects on breathing and quality of life. It presents as one of the most difficult problems for the laryngologist. Located at the crossroads of the respiratory tract and food passages, the larynx provides 3 important functions: airway protection, respiration and phonation which are affected by paralysis of one or both vocal folds. Careful history taking and physical examination, including laryngoscopy are required for adequate evaluation. Precise diagnosis allows the surgeon to intervene correctly and at the right time. Most patients with BVFP have an accepted voice with short phonation time, but their airway is usually compromised, and the degree of airway compromise can vary from mild dyspnea associated only with effort to life-threatening airway obstruction depending on the position of the immobile vocal folds and on the cardiopulmonary reserve. It is a sign of illness and not a diagnosis per se. The most reasonable approach to patients with BVFP is to enlarge the glottic airway in a step-wise manner. The most common cause of this condition is iatrogenic especially after total thyroidectomy. This was a prospective study that was carried out on 20 patients with BVFP who were subjected to endoscopic/assisted microscopic posterior cordotomy at the Department of Otorhinolaryngology, Tanta University Hospital. The study started from first February 2019 till the completion of the study. |
