N2 - Purpose: This study was performed to evaluate the incidence and contributing factors of complications associated with medialization laryngoplasty using Gore-Tex in patients with unilateral vocal fold paralysis. Methods: A retrospective chart review was conducted for all patients who underwent medialization laryngoplasty using Gore-Tex at Tohoku University Hospital between January 2014 and April 2018. A search of series and case reports in PubMed was performed to determine the incidence of complications following medialization laryngoplasty using Gore-Tex. Results: Sixty-eight patient charts were reviewed. Two patients (2.9%) had complications (infection and extrusion into the airway) related to the Gore-Tex implant after surgery. In the 555 medialization laryngoplasty cases reported in both our current data and eight additional articles, there were 11 complications related to the Gore-Tex implant (2.0%). The most common event was extrusion into the lumen, which occurred in six cases (1.1%), followed by persistent inflammation with the granulation formation (0.5%). There were 12 cases of Gore-Tex extrusion (one male, six female, and five of unknown gender). The interval to onset ranged from 1 month to 10 years (median, 49 months). Conclusions: Our findings serve as a reminder that complications can occur with Gore-Tex implants following medialization laryngoplasty in patients with unilateral vocal fold paralysis, even in the long-term. We suggest that the use of excessively large implants in women and occurrence of postoperative hematoma followed by infection are factors that may cause complications. Nevertheless, Gore-Tex has been proven to be a relatively safe and reliable material for medialization laryngoplasty.
