Making Headway in Surgical Education at Home and Abroad: Use of an Inexpensive Three-Dimensional Learning Model to Improve Plastic Surgery Resident Confidence in Mohs Defect Assessment and Closure Planning. | LitMetric
Background: 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.
Methods: 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.
Results: 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).
Conclusion: 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.
Hyperbaric oxygen (HBO) therapy has emerged as a potential treatment, shown to enhance blood flow and angiogenesis. However, specific effects and mechanisms of HBO on limb ischaemia responding to a hypoxic environment remain largely unknown. We aimed to investigate the therapeutic potential of HBO in the treatment of limb ischaemia.
Importance: The diagnosis of congenital auricular deformity often relies on the clinical experience of clinicians, leading to a high incidence of misdiagnosis and missed diagnosis due to the lack of quantitative diagnostic criteria.
Objective: To characterize auricle morphology in newborns from southern China and explore the underlying etiology of congenital auricle deformity.
Methods: A total of 636 neonates (1272 ears) with less than seven days old were included.
Pressure injuries, particularly among patients with spinal cord injuries and the elderly, significantly contribute to morbidity, mortality, and financial sequelae. Surgical interventions, including debridement and flaps, may improve outcomes, especially for stage 3 and 4 pressure injuries. This survey assesses Canadian plastic surgeons' perspectives and practices regarding the surgical management of these injuries.
Amelogenesis imperfecta refers to a group of hereditary diseases that affect dental enamel, often leading to a wide range of clinical manifestations and aesthetic concerns. This case report describes a female patient diagnosed with amelogenesis imperfecta associated with a skeletal open bite. The treatment approach was multidisciplinary.
Background: Acne is a common inflammatory dermatosis. Although gender-related differences in prevalence and age of onset have been documented. Other gender-related characteristics of acne have not been well elucidated yet.
