Background: The purpose of this study was to review our surgical strategy and outcomes of drain-less, subcutaneous suture technique in standard simple elliptical incision on preauricular sinus (PAS) cases.
Methods: The clinical records of 198 patients (247 ears) with PASs who were operated via standard simple elliptical incision with drain-less, subcutaneous suture technique by a single surgeon (K.H.P.) between January 2008 and December 2018 were reviewed for analysis. Patients' demographics, location of PASs, previous incision and drainage (I&D) history, previous surgical excision history, duration of follow-up, postoperative infection after surgery, and recurrence after surgery were analysed.
Results: Out of 247 PASs, 18 (7.3%) cases had postoperative infections and 11 (4.5%) cases showed recurrence. Postoperative infection rate were higher in previous I&D groups (PIDGs, 9.8%) and previous fistulectomy groups (PFGs, 10%), and also recurrence rates of PFGs (10%) was higher than those of fresh cases. However, there were no statistically significant differences between these groups. In addition, PAS patients with postoperative complications such as infection and recurrence were more common in male patients.
Conclusion: We report a method of drain-less standard simple elliptical incision for the surgical removal of PAS and the outcomes of the surgery. Our method showed a low recurrence rate and low chance of wound infection postoperatively not only in fresh cases but also in pre-operative I&D cases and even previous fistulectomy cases. In conclusion, our method is proposed as an effective and safe method in all kind of patient groups, without presenting post-operative discomfort to patients.
