Spontaneous displacement of silastic prosthesis 10 years after type 1 thyroplasty: a case report

Implant dislocation following type 1 tyroplasty mostly results from the effects of triggering factors in the early postoperative period. A 42-year-old female patient who had had tyroplasty type 1 surgery with silastic implant, applied to our clinic with cough episodes, dyspnea and hoarseness following an upper airway infection 10 years after the surgery. In laryngeal endoscopic examination of the patient, white colored irregularity on anterior left vocal cord and left band ventricule fullness was seen. Regarding the patient's medical history, it was thought that the silastic prosthesis which had been implanted in the type 1 thyroplasty surgery might have displaced. The silastic prosthesis was removed by means of microsurgery technique through endolaryngeal way under general anesthesia. During the first month follow-up of the patient, dyspnea and hoarseness complaints were improved right away and she had no other problems. The causes and consequences of displacement of the prothesis which rarely occurs, after tyroplasty type 1 have been discussed along with the latest data in the literature.
