Summary

This study evaluated bacterial contamination during head and neck cutaneous surgeries. A clean technique significantly reduced aerobic bacteria, indicating low infection risk for healthy patients undergoing office-based procedures.

Area of Science:

  • Dermatology
  • Surgical Microbiology
  • Infection Control

Background:

  • Cutaneous surgeries, especially on the head and neck, carry a risk of bacterial contamination.
  • Evaluating bacterial load is crucial for assessing infection risk in office-based surgical settings.

Purpose of the Study:

  • To quantify bacterial contamination during head and neck cutaneous surgeries.
  • To assess the efficacy of antiseptic application in reducing bacterial counts.
  • To compare bacterial contamination in immediate closure versus prolonged procedures.

Main Methods:

  • Microbiologic counts were used to determine aerobic bacterial contamination.
  • Surgical fields were sampled three times: before antiseptic, 30 seconds after, and before closure.
  • Two groups were studied: immediate closure (Group A, n=10) and prolonged procedures like Mohs surgery (Group B, n=15).

Main Results:

  • Both groups showed a statistically significant reduction in aerobic bacteria after antiseptic application and before closure.
  • All bacterial counts were below 100,000 colony-forming units/cm2 at both post-antiseptic time points.
  • No significant difference in bacterial reduction efficacy was noted between immediate closure and prolonged procedures.

Conclusions:

  • A clean surgical technique effectively reduces bacterial contamination in head and neck cutaneous surgeries.
  • Office-based surgical environments provide low-risk conditions for infection in relatively healthy patients.
  • Antiseptic application is a critical step in minimizing bacterial load during these procedures.
