Vocal fold injection
Vocal fold paralysis, vocal fold paresis, vocal fold atrophy, sulcus vocalis, severe vocal fold scar, soft tissue loss of the vocal fold(s)
Bilateral vocal fold immobility/hypomobility, coagulopathy (relative)
General anesthesia and endotracheal intubation; liposuction is performed after sterile prep and draping; microsuspension laryngoscopy can be performed as a clean procedure.
Check coagulation status if patient is anti-coagulated.
Anatomy and Landmarks
Make a 5mm abdominal incision in the right lower quadrant of the abdomen. Aim liposuction cannula opening upwards in the subcutaneous plane to prevent accidental penetration into deep abdominal contents.
Advantages: provides a large amount of autologous injectable material, less invasive compared to a medialization laryngoplasty, expedient.
Disadvantages: 10-15% revision rate due to fat resorption.
Airway obstruction, infection and/or hematoma at the abdominal liposuction site, overinjection, underinjection, fat resorption requiring revision surgery.
