[Laryngeal paralysis and laryngospasm].
The intrinsic laryngeal muscle potential was recorded with electromyography. Vocal cord movements were observed by a video stroboscope. Laryngeal paralysis is divided into mild, moderate, and severe degrees based on the potentials of intrinsic laryngeal muscles and on the status of vocal cord movements. In the past 11 years (from 1983 to 1993) 1211 cases were diagnosed as having mild, moderate, and severe laryngeal paralysis. Among them, there were 11 cases with laryngospasm including 3 mild, 2 moderate, and 6 severe cases. The findings obtained from careful observation on these 11 cases of laryngospasm demonstrated that there were certain relationships between laryngeal paralysis and laryngospasm. During the course of exacerbation or restoration of paralysis, the laryngospasm may occur.
