Objective: After excision of a preauricular sinus, a head bandage compressive dressing is usually used to reduce dead space and to decrease the risk of recurrence. However, such use of a head bandage may cause various problems. We assessed a new method of compressive dressing, using suture transfixion of silicone sheets to the former sinus tract, following preauricular sinus excision.
Methods: This retrospective study reviewed the medical records of patients undergoing preauricular sinus excision in a tertiary referral centre over a five-year period. After excision of the preauricular sinus, patients underwent suture transfixion of silicone sheets. Post-operative outcomes were analysed.
Results: The new dressing method was performed on 50 ears of 37 patients. The post-operative incidence of recurrence and haematoma formation was 4 and 2 per cent, respectively. Other problems possibly caused by head bandaging, such as headache, facial flushing, and nausea and/or vomiting, were not observed.
Conclusion: Compressive dressing by suture transfixion of silicone sheets is safe and effective following preauricular sinus excision.
