Background:
Fat injection laryngoplasty has been used at the Sydney Voice Clinic for selected cases of unilateral vocal fold paralysis since 1989.
Methods:
Forty-five consecutive cases deemed suitable for treatment by this technique are presented in this paper.
Results:
Mean follow up for this group of patients was 33 months. Over the period of follow up, 39 of the 45 patients achieved normal or near normal voice, with four patients requiring additional surgical intervention.
Conclusion:
Fat injection laryngoplasty is a quick, simple, inexpensive and reliable procedure, with few complications and good long-term results in suitable selected cases of unilateral vocal fold paralysis.
