喉麻痹与喉肌痉挛

用肌电图仪测定喉内肌电位，用电视频闪放大喉镜录相观察声带运动状态，将喉麻痹程度分为轻、中、重度三类。从１９８３～１９９３年的１１年中遇到轻、中、重度喉麻痹１２１１例，在１２１１例中伴有喉肌痉挛者１１例，其中重度喉麻痹伴有喉肌痉挛者６例，中度者２例，轻度者３例。通过１１例的观察，发现喉麻痹在进行或治愈的过程中皆可出现喉肌痉挛。

Laryngeal Paralysis and Laryngospasm

The intrinsic laryngeal muscle potential was recorded with electromyography.Vocalcord movements were observed by a video stroboscope. Laryngeal paralysis is divided into mild, moder-ate,and severe degrees based on the potentials of intrinsic laryngeal muscles and on the status of vocalcord 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 includ-ing 3 mild, 2 mederate,and 6 severe cases. The findings obtained from careful observation on these 11cases of laryngospasm demonstrated that there were certain relationships between laryngeal paralysis andla ryngospasm. During the course of exacerbation or restoration of paralysis,the laryngospasm may occur.
