| Abstract;A series of 28 cases of bilateral laryngeal nerve paralysis treated in our department during the period from July 1971 to November 2002 was reported. There were 17 males (mean age; 61 years) and 11 famales (mean age; 51 years). Among their chief complaints, hoarseness was the most common (12 cases), followed by dyspnea (9 cases). Dysphagia was noted in 11 out of the 28 cases. The vocal cords were fixed at the median position in 12 cases, paramedian position in 7, and the intermediate position in one case. In 5 cases, the paralysis was incomplete. In the remaining 2 cases, a fixed position was not recorded. As for the cause of their paralysis, 14 cases developed paralysis immediately after surgery, namely thyroid surgery in 9, esophageal surgery in 2, and cardiovascular surgery in 3. Non-surgical causes were malignancy in 5 cases, intubation in one case, and idiopathic in 7 cases. In the single remaining case, paralysis developed after trauma on one side and then idiopathic paralysis was noted on the other. Tracheotomy was performed in all cases except 3. As for the method of glottoplasty, the anterior opening method was the most commonly (9 cases) used in our department. In 3 out of the 28 cases, a spontaneous recovery was noted. It was concluded that glottoplasty is only indicated after an observation period of at least 6 months after the onset of paralysis. (author abst.) |
