Thirty-nine patients were treated with GAX collagen for vocal fold augmentation. The objective results were evaluated by measurement of the maximum phonation time, the phonatory quotient, vocal frequency analysis, and laryngostroboscopy. These results are as good as those with Zyderm Collagen II (ZCI). Avoidance of useless overcorrection, better resistance to collagenase, and less induced hypersensitivity differentiate GAX from ZCI.
39名患者接受了GAX胶原蛋白治疗以进行声带增厚。通过测量最大发声时间、发声商、嗓音频率分析和喉动态镜检查对客观结果进行评估。这些结果与使用Zy derm胶原蛋白II（ZCI）的结果一样好。避免无效的过度矫正、对胶原酶有更好的耐受性以及较少引起超敏反应，这些是GAX与ZCI的不同之处。
