Modification of thyroplasty type I

Abstract

Thyroplasty Type I is a popular surgical procedure used to treat unilateral recurrent laryngeal nerve paralysis. We modified this operation, and removed free cartilage in four cases. If neccessory, the inner perichondorium was incised. The thyroplasty implant (silicon plug) was fixed in place with 4-0 nylon. The post-operative results were satisfactory in most cases. This is an easy procedure that can be used to control the force of compression. The plug can be easily fixed in place using 4-0 nylon because the space between the window and the inner perichondorium is widend by the remoral of free cartilase, however, it can also sometimes result in hemorrhaging and inflammation. The removal of cartilage from the window facilitetes thyroplasty Type I.
