Outline
• Efficient undermining
• Adhesive strip skin closure
• Negative pressure device
• Phone based apps
Undermining techniques
• Cold steel
– Sharp
– Blunt
• Electrosurgery
Electrosurgical Undermining
• Advantages
– Decreased operative time
– Decreased bleeding
• Disadvantages
– Collateral tissue damage
– Wound edge necrosis
– Vascular compromise

Surgical smoke
• Health risk
• Particulate matter
• Toxic chemicals
• Infectious agents
• Patient dissatisfaction

surgery: A Randomized Controlled Trial. J Am Acad Dermatol. 2017 Nov 11. pii: S0190-9622(17)32685-3.
Surgical smoke
• Ablation of 1 gram of tissue produces a
smoke plume with an equivalent
mutagenicity to 6 unfiltered cigarettes
• On average the smoke produced daily in
plastics OR was equivalent to 27 to 30
cigarettes

1,000 Mohs cases/year = 50 hours
of continuous smoke exposure

pulmonary function abnormalities in Gulf War I Veterans. Arch Intern Med. 2004 Dec 13-27;164(22):2488-91.
• The distribution of pulmonary function test
results was identical among deployed and non-
deployed veterans.
• Findings did not confirm the hypothesis that
deployment to the Gulf War in 1990-1991
resulted in an increased prevalence of clinically
significant pulmonary abnormalities 10 years
later.

Iraq/Afghanistan Veterans. Paper presented at: 2014 American Thoracic Society International Conference. May 2014; San Diego.
• 63 Gulf War veterans approximately 20 years post-deployment
• Significantly higher rates of small airway obstruction (5x) and restrictive lung physiology (2x) at 20-years post-deployment compared to at 10-years post-deployment
Adhesive strips
• Quicker than sutures for
closing surgical wounds
• Reduces wound care burden
• Barrier function
• No risk of sharps injury
