RESUMO
OBJECTIVE: To evaluate the effect of prophylactic antibiotics on outcomes and complications following surgical reconstructions of nasal Mohs defects in the outpatient setting. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care center, July 2021 to June 2023. METHODS: All adult patients who underwent reconstruction of nasal Mohs defects in an outpatient office setting were examined. Patient demographics, surgical details, prophylactic postprocedural antibiotic use, and postprocedural complications (infection, flap or graft necrosis, wound dehiscence) were collected. Outcomes and complications were compared between patients who received and did not receive prophylactic antibiotics using χ2, Kruskal-Wallis, and multivariable logistic regression. RESULTS: A total of 211 patients met inclusion criteria. A majority of reconstructions utilized a local flap (70%), followed by a skin or composite graft (22%), then an interpolated flap (8%). Over half of patients (55%) were prescribed prophylactic antibiotics. Postprocedural complications were documented in 16 patients (7.6%), including infection (3.3%) and flap or graft loss or necrosis (1.4%). The rate of complications did not differ based on receipt of antibiotics. The only factors independently associated with the development of complications were history of chemoradiation and reconstruction with skin or composite grafts. CONCLUSION: Prophylactic antibiotics after nasal Mohs reconstructions performed in the office setting were not associated with any differences in the rate of postprocedural complications, including surgical site infections.
