    • A vocal cord medialization prostheisis (10) includes a preformed and presized vocal cord engagement member (12). The engagement member (12) has a base surface (18) and an engagement surface (20) that is inclined a predetermined amount with respect to the base surface (18). Measurement indicia (34) are provided on the engagement member (12) to indicate elevation of the engagement surface (20) at predetermined points along the prosthesis. A vocal cord medialization tool (50) is used to measure displacement of a vocal cord (96) to an optimum phonation and breathing position before insertion of the prosthesis (10). The medialization tool (50) provides measurements that correspond to the sizing indicia (34) on the prosthesis (10). The prosthesis (10) can thus be trimmed to eliminate elevations that are unnecessary for obtaining optimum positioning of a vocal cord. One embodiment of the medialization tool (50) also includes provision (132,134) for measuring the thickness of a thyroid cartilage (92).
    • 声带内侧化假体(10)包括预先形成并预先声音的声带接合构件(12)。 接合构件(12)具有基部表面(18)和相对于基部表面(18)倾斜预定量的接合表面(20)。 测量标记(34)设置在接合构件(12)上以指示接合表面(20)沿着假体的预定点处的升高。 在插入假体(10)之前,使用声带中间化工具(50)来测量声带(96)的位移至最佳发声和呼吸位置。 中间化工具(50)提供对应于假体(10)上的尺寸标记(34)的测量。 因此可修整假体(10)以消除为获得声带的最佳定位所不需要的高度。 中间化工具(50)的一个实施例还包括用于测量甲状软骨(92)的厚度的设备(132,134)。
