Complications after type one thyroplasty: is day-case surgery feasible?

Abstract

AbstractObjectives and hypothesis:Isshiki type one medialisation thyroplasty is an accepted treatment for a unilateral immobile vocal fold. It can also be performed simultaneously as a bilateral procedure in patients with severe bowing of the vocal folds (e.g. presbyphonia). The objectives of this study were to assess the incidence and timing of post-operative complications, and to evaluate whether patients undergoing this operation could, in future, be treated as day cases.Study design and methods:A retrospective analysis was undertaken of 57 consecutive patients who had undergone a type one thyroplasty (52 unilateral and five bilateral) at a tertiary referral centre between April 2003 and April 2006. Post-operative improvement in the voice (measured subjectively, perceptually and quantitatively) was considered to constitute a successful outcome. Any complications were documented.Results:Fifty-seven patients who had undergone laryngeal framework surgery were recruited from the study database. All of these patients had undergone either unilateral or bilateral type one medialisation thyroplasty but no arytenoid surgery. Thirty-seven were male (65 per cent) and 20 female (35 per cent), and there was left-sided predominance (74 per cent). All patients were discharged the morning following afternoon surgery (i.e. within 24 hours). Complications occurred in four patients (7 per cent). One patient, who was taking warfarin, developed a post-operative haematoma which resolved with conservative treatment. Two patients (both of whom had undergone revision thyroplasty) developed a wound infection three days post-operatively, which resolved with antibiotics. One patient returned with hoarseness five months post-operatively, after an initially successful result. This patient had previously received radiotherapy for early glottic carcinoma, and the Silastic® implant was eroding through the mucosa. This was subsequently removed under general anaesthesia. No patients developed complications leading to airway compromise.Conclusion:The only complications in this series were in patients taking anticoagulation medication, undergoing revision surgery, or in whom the laryngeal tissue was atrophic or absent. Careful patient selection to exclude any of the above should reduce the risk of complications. The authors would therefore advocate type one thyroplasty for unilateral or bilateral vocal fold paralysis as a suitable procedure for day-case surgery within our department.
