The Montgomery® Thyroplasty Implant System
The Montgomery® Thyroplasty Implant System is the result of over a decade of research and development. Designed to treat unilateral vocal cord paralysis, this revolutionary new system is standardized, eliminating the time-consuming process of customizing implants at the time of surgery. Standardization translates to consistent results. Solid clinical experience involving hundreds of patients has produced outstanding voice improvement while reducing long procedures and complications associated with hand-carved implants and Teflon® injection.
The unique design of the Montgomery® Thyroplasty Implant consists of two major components: the rectangular base and the triangular top. The base is constructed of firm silicone and features three tiers. The lateral, or outer tier, remains on the outer surface of the thyroid lamina and prevents medial displacement of the implant. The middle tier stabilizes the implant and prevents rotation. The inner tier rests against the inner surface of the thyroid lamina and prevents outward displacement. There is a common base for females and a common base for males.
The system consists of specially designed surgical instruments, devices for measuring medialization distance prior to implant insertion, and a range of five implant sizes for female patients and five sizes for males. The implants are constructed using implant grade silicone which has undergone extensive biocompatibility testing.
The triangular top is made using soft silicone and serves to medialize the vocal cord and the vocal process of the arytenoid. The hypotenuse of the triangle is designed to correspond to the long axis of the vocal cord when it is in the medial position. The height of the triangle is measured in millimeters and is available in sizes 6, 7, 8, 9 and 10 mm for females and sizes 8, 9, 10, 11 and 12 for males.
The surgical procedure has been fine-tuned and involves a step-by-step process for locating the thyroplasty window, creating the window, determining implant size, and inserting the implant. The procedure reduces surgery time and is completely reversible. A procedural video demonstrating the surgical procedure is available.
Special measuring devices have been designed to accurately simulate vocal cord medialization without the need to insert and replace multiple implants. This results in less trauma to the patient and reduced surgery time. The disposable set includes all five sizes to correspond to the implants and is available in both female and male configurations.
A complete set of surgical instruments to facilitate this procedure is available. There are instruments designed for locating, designing and creating the window, and instruments for inserting the implant.
