Teflon injection has been used for vocal fold medialization following
paralysis. Recently, numerous articles have discussed the complications
of Teflon injection, including overinjection, airway obstruction, Teflon
granuloma, and an abnormal mass effect creating a decreased vibratory character
of the true vocal fold. Multiple techniques for Teflon removal have been
described. This report details our experience with complete Teflon granuloma
removal via a lateral laryngotomy under local anesthesia. Microscopic dissection
of the entire granuloma and the paraglottic space was accomplished in all
patients. Due to extensive destruction caused by the granuloma, the vocal
ligament was resected in 3 patients; it was partially resected and reanastomosed
in 1 case, and spared in 6 patients. Laryngeal reconstruction was accomplished
with an inferiorly based sternohyoid muscle rotation flap and arytenoid
adduction. Effortful speech secondary to pressed vocal quality resolved
in all patients. Near-normal to normal vocal quality was obtained in 4
patients, with the average "voice desirability" improving 60% and the effective
glottic width increasing 29%. Factors that contributed to a successful
outcome included noninvolvement of the vocal ligament and sparing of the
mucosal cover.
