          Abstract

          Objective

          Training models are required to impart surgical skills, like wound closure techniques, prior to practice in patients. In an ideal case, the tissue characteristics of the model are close to those of humans, easy to create and of low cost.

          Methods

          Here, we describe a model to train students in wound closure technique using conventional chicken legs obtained from the supermarket.

          Results

          The described model has good tissue characteristics, does not require any lavish preparation and is of minimal cost (0.62 Euro or 0.78 USD).

          Conclusions

          Chicken legs appear to be an appropriate tool for teaching wound closure techniques.

          Learning the surgical craft: a review of skills training options.

          Surgical practice is undergoing fundamental changes, and this is having a significant effect on the training of surgeons. Learning the craft of surgery is threatened by reduced elective operative exposure and general service cuts within public teaching hospitals, safer working hour legislation and pressures to accelerate the training of young surgeons. Rapid technological changes mean that 'old dogs' have to teach 'young dogs' many new tricks in a relatively adverse environment. This review outlines the great variety of resources available for skills-based training outside the operating room. These resources are ready to be used as a necessary adjunct to the training of competent surgeons in Australasia.

            Teaching technical skills: training on a simple, inexpensive, and portable model.

            The purpose of this study was to determine whether surgical residents could significantly improve their performance on a specific surgical procedure after a brief practice session with feedback. Attending plastic surgeons, using valid and reliable checklists and global rating scales, objectively assessed 37 junior surgical residents while performing two-flap Z-plasties on pig thighs (one before and one after a one-on-one, 5-minute practice session with feedback). The total cost per resident was $1.00 (Canadian currency). After the practice session, total checklist scores improved from 7.3 (range, 1 to 9) to 7.9 (range, 5 to 9), and the total global rating scores improved from 29.1 (range, 13 to 41) to 31.9 (range, 19 to 43). Paired Student's t tests revealed significant improvement in both the mean total checklist scores (p < 0.05) and mean total global rating scores (p < 0.01). Also, the global rating score for appearance and quality of the final surgical product significantly improved from 2.7 to 3.3 after the practice session (p < 0.01). There were no significant differences in performance scores between men and women, between first-year and second-year residents, with residents' previous experience with the Z-plasty procedure, or with resident's base surgical specialties. The results of this prospective study indicate that training on a simple and portable model with very brief individualized practice and feedback is an effective and inexpensive way of improving resident performance. A 5-minute practice session with a surgical trainee before performing a procedure on a living patient may significantly improve the patient's surgical performance and produce a superior result.

              Z-plasty: a concise review.

              One of the most commonly used techniques in facial plastic surgery is the Z-plasty. Main reasons to perform these transposition flaps are to lengthen a pre-existing scar, to camouflage a scar, or to realign a scar. The classic 60 degrees Z-plasty allows a 75% increase in scar length and is the cornerstone against which all variations are compared. Understanding the classic Z-plasty permits the surgeon to expand his or her repertoire to include the numerous variations thereof. The double-opposing Z-plasty, unequal triangle Z-plasty, four-flap Z-plasty, compound Z-plasty, and planimetric Z-plasty are the most frequent variants of the basic Z-plasty. Each are presented with illustrations and clinical indications.
