Flaccid laryngeal nerve paralysis may be treated by vocal fold augmentation with Teflon injection, which is successful to various degrees depending on the subjective interpretation of the patient or clinician. A new material, Phonogel, consisting of cross-linked bovine collagen, is available but not approved for human use in this area. Ten dogs were submitted to videostroboscopy, photoglottography, electroglottography, and acoustic analysis in the normal state, with stimulated recurrent laryngeal nerve paralysis, and with injection of either Teflon or Phonogel. A statistical comparison and the advantages and disadvantages of each material are discussed in relation to this study and its clinical use.
弛缓性喉神经麻痹可通过注射特氟龙进行声带增强治疗，其成功程度因患者或临床医生的主观判断而异。一种由交联牛胶原蛋白组成的新材料Phonogel已可供使用，但尚未获批用于该领域的人体治疗。对10只犬在正常状态、喉返神经麻痹刺激状态下，以及注射特氟龙或Phonogel后进行了频闪喉镜检查、光声门图检查、电声门图检查和声分析。结合本研究及其临床应用讨论了每种材料的统计学比较以及优缺点。
