Making Headway in Surgical Education at Home and Abroad: Use of an Inexpensive Three-Dimensional Learning Model to...

The development of simulation, particularly low-cost models, has become a focus of interest within plastic surgery education. Current simulators for Mohs reconstruction are either expensive or not reusable. The authors hypothesize that using a Styrofoam head model during an interactive teaching session will positively affect plastic surgery trainee comfort in designing Mohs reconstructive options.

A cohort of integrated plastic surgery residents at a single institution performed a preactivity questionnaire to obtain baseline comfort in defect assessment and design for five Mohs defects. They subsequently underwent an interactive learning session and were instructed to design flaps on life-size Styrofoam heads with feedback from the senior author (M.L.B.). A postactivity questionnaire was completed to assess improvement in comfort in defect assessment and flap design. Three attending surgeons then compared trainee designs with the senior author's design to assess accuracy. All surveys were based on a five-point Likert scale.

When analyzing all defects, average postactivity scores increased by 0.63 (SD, ±0.24) ( P = 0.008). Junior residents ( n = 8) had a greater increase in average score responses [mean, 1.07 (0.5 to 1.75)] compared with senior residents ( n = 9) [mean, 0.27 (0 to 1)] ( P < 0.001). When assessed by senior-level surgeons, senior residents had significantly greater accuracy in design for each defect ( P < 0.05) except cheek advancement flap ( P = 0.08).

Participation in an interactive educational activity using a Styrofoam head model demonstrated significant improvements in trainee assessment and design of reconstructive options for Mohs defects.
