Abstract
Abstract Aim BAHA implants utilise bone conduction to treat hearing loss. The aim of the study was to understand the complication rate of patients receiving the implant compared to other studies and to identify any causative factor. Recommendations would therefore be made to reduce these complications. Methodology A retrospective cohort study was undertaken on 134 patients who received a BAHA implant performed by a single surgeon at Salford Royal NHS Foundation Trust between 01/01/2016 to 31/12/2018. Data collected identified complications of the surgery, whether or not the abutment was still in situ and whether the patient had any comorbidities or history of smoking Results 33.6% of the patients had no complications after surgery with the remaining 66.4% having at least one complication. BAHA connect devices had a 67.2% complication rate, attract devices had a 33% complication rate. 13.6% of BAHAs were extruded. There was no positive correlation between either smoking or diabetes and poorer complication rate. Conclusion Implant extrusion can be prevented with irrigation cooling of the drill site. Immobilisation of the implant, proper wound care with brushing and using an Allevyn Acticoat 7 wound dressing improves outcomes. Attract systems have fewer complications rates so must be maximised where appropriate.
