Two straightforward additions to the Mohs surgery suite — three-dimensional anatomical models and surgical smoke evacuators — measurably improve patient satisfaction, according to a new report highlighted by Bioengineer.org.

The finding matters for a high-volume skin cancer procedure. Mohs micrographic surgery is the standard of care for many keratinocyte carcinomas on the head and neck, and it demands long patient waits while tissue margins undergo staged microscopic examination. That waiting period, combined with the sensory realities of the procedure room, shapes how patients judge the experience as much as the oncologic outcome does.

Three-dimensional models appear to address the informational gap. Patients facing Mohs surgery routinely underestimate the size of the surgical defect, the extent of reconstruction, and the time the procedure requires. A physical model in the consultation room lets the surgeon show, rather than describe, what staged excision involves. The report positions this as a simple intervention: no new device certification, no major capital outlay, no change to the surgical technique itself.

Smoke evacuators target a different dimension of the patient experience. Electrocautery generates surgical plume, and patients frequently cite the smell of burning tissue as one of the most unpleasant elements of any cutaneous procedure. Evacuation systems that clear the plume at the point of generation remove that sensory trigger. Like the 3D models, evacuators represent a modest equipment decision rather than a workflow overhaul.

The framing deserves attention from a practice-management standpoint. Patient satisfaction scores now feed directly into reimbursement conversations, online reputation, and referral patterns. Interventions that move those scores without adding operative time or clinical risk are rare. If a printed model and an evacuator hose accomplish what the report suggests, the return on investment calculation is short.

The occupational-health angle strengthens the case for the smoke evacuator in particular. Surgical plume contains particulate matter and chemical byproducts, and perioperative staff absorb chronic exposure that patients do not. A device justified on patient-comfort grounds may simultaneously address a workplace-safety gap that has drawn increasing regulatory scrutiny.

Derm Field notes the obvious caveat: the details of the underlying study design — cohort size, satisfaction instrument, and follow-up window — were not specified in the summary report. Practices considering adoption will want the primary data before drawing firm conclusions about effect size.

What the report does establish is direction. The interventions are cheap, fast to implement, and low-risk. As value-based metrics and patient-reported outcomes take a larger share of the dermatology quality agenda, expect inexpensive perioperative modifications like these to move from optional to standard in the Mohs suite.
