One of the most widely accepted surgical technique for improving unilateral vocal cord palsy is the medialization thyropflasty. Adequate placement of the prosthesis is essential for optimal results. Some authors have developed mathematical models to estimate the position of the vocal cord, which can provide an idea of its location, but these models are unreliable due to inter-individual differences. That is the case for the Montgomery prosthesis (Boston Medical Products, Westborough, USA), one of the most widely used models. Its location is based on gender criteria, which can lead to a slightly displaced prosthesis, thus giving suboptimal results (Fig. 1). This article presents a surgical procedure and set of measurement devices designed to achieve accurate individualized placement of the Montgomery prosthesis. The initial results of a small series are presented.
