Background: The resultant dysphonia and aspiration in unilateral vocal cord palsy can be overcome with
medialisation thyroplasty. With this background, we aim to determine the aetiology of the unilateral vocal
cord palsy and effectiveness of the phonosurgical procedure with Gore-Tex as a sole treatment. Methods:
Within a seven year period, 37 Gore-Tex medialisation thyroplasty were performed for unilateral vocal cord
palsy at our institution and medical records were retrospectively reviewed. Results: There were 18
males and 19 females with mean age of 48.7 years (range 19–81 years). The predominant aetiology was
thyroidectomy (43.2%) with benign thyroid disease predominates (n=13) over thyroid malignancy (n=3). Voice
outcome was evaluated subjectively using visual analogue scoring system, results indicating that Gore-Tex
medialisation thyroplasty was effective in addressing dysphonia in 62.5% (n=15) patients. However it alone
cannot address aspiration seen in those with high vagal nerve lesion. Airway compromise occurred in two
cases postoperatively (5.4%) presenting as acute stridor. Conclusion: In unilateral vocal cord palsy, Gore-Tex
medialisation thyroplasty can effectively improve the resultant dysphonia and often accompanying aspiration
which would otherwise be disabling for the patients.
