Tobacco Use and Skin Reactivity in Patients With Percutaneous Auditory Osseointegrated Implants.

Abstract

To determine if there is an association between tobacco use and the development of postoperative skin reactions in patients undergoing percutaneous osseointegrated auditory implant (pOAI) surgery. Single surgeon retrospective cohort study. Academic medical center. Retrospective chart review was performed on all patients who underwent pOAI. Smoking status (current and former users versus never-users) was recorded as were numerous demographic and surgical variables. The primary outcome measure was skin reactivity as measured by Holgers score. Secondary outcomes studied included total number of problem visits, minor interventions, and major interventions. 126 patients, 73 with no tobacco history (NT) and 53 with a positive smoking tobacco history (T) underwent pOAI surgery in this study. The T group was found to have higher rates of first postoperative visit soft tissue reactions compared with the NT group (24.5% versus 6.8%, p 1/4 0.011, odds ratio [OR] 4.42, 95% confidence interval [CI]: 1.5, 13.3), but not at long-term follow-up. When former smokers were eliminated from analysis, differences were also found at long- term follow-up (40.9% versus 19.2%, p 1/4 0.037, OR 2.92, 95% CI [1.0 - 8.1]). There were no differences in total number of problem visits or total number of minor or major interventions. Patients with a history of tobacco use have a significantly higher rates of skin reactivity compared with patients without, though smoking cessation may partially mitigate long-term risks. Surgeons should be aware of the risks of early skin reactivity and should counsel patients accordingly.
