Purpose: This study investigates the post-operative infection rates between two surgical approaches: linear incision and the punch technique for bone anchored hearing systems. Secondarily, it investigates the impact of smoking, comorbid disease, and operative conditions on post-operative skin reactions and infections. Methods: A retrospective study was conducted at a single tertiary care institution. A single surgeon completed either of the two techniques on adult patients with mixed, conductive hearing loss, or single sided-deafness. Patients included had at least 6 months follow-up, and were evaluated for preexisting illnesses, perioperative complications, length of surgery, and post-operative complications including infection after surgery. Post -operative soft tissue around the abutment was assessed with Holgers Classification scale. Results: Fifty-one patients were included in this study, 28 female and 23 males with an average age of 68.8. Thirty-three patients underwent linear incision surgery and 18 had the punch technique. Overall 9 patients (17.6%) had post-operative infections requiring topical or oral antibiotic treatment. Six (18.2%) were in the linear group and 3 (16.7%) in the punch group. There was no statistically significantly difference (p = 1). A multivariate analysis compared age, sex, obesity, DM, operative time, skin thickness, and abutment size to postoperative skin infection rates requiring treatment. Only DM was statistically correlative with infection (p = 0.02). Conclusion: No significant differences in post-operative infections were identified comparing linear incision and the punch techniques. Patients with diabetes had a higher incidence of post-operative skin infections rates.
