Abstract
OBJECTIVE: To compare clinical outcomes and complication rates in patients undergoing injection laryngoplasty performed under local versus general anaesthesia.
METHODS: A retrospective review was conducted of patients who underwent injection laryngoplasty performed by a single laryngologist in a tertiary Australian laryngology centre, between February 2013 and December 2014. Patient demographics, anaesthetic modality and complications were recorded. Voice Handicap Index 10 and the Grade, Breathiness, Roughness, Asthenia, Strain scale were evaluated.
RESULTS: Thirty-four laryngoplasties were performed under general anaesthesia and 41 under local anaesthesia, with mean patient ages of 59.5 and 68.8 years, respectively. Voice Handicap Index 10 scores were significantly improved post-injection (p 0.05). All aspects of the Grade, Breathiness, Roughness, Asthenia, Strain scale showed significant improvement post-injection, except asthenia. There were seven (9.3 per cent) minor complications (five in the general anaesthesia group, two in the local anaesthesia group), all managed conservatively.
CONCLUSION: Injection laryngoplasties performed under general anaesthesia and local anaesthesia offer similar voice outcomes, with comparable complication rates. Hence, development of a management algorithm for injection laryngoplasties performed under local anaesthesia is recommended.
