Anomalous Extensor Indicis Proprius Muscle Extending Beyond the Extensor Retinaculum: A Case Report.

CASE: During dissection of the upper limb of a cadaver in preparation for a first-year anatomy course, an extensor indicis proprius (EIP) variant was discovered with its muscle belly extending distal to the extensor retinaculum and beyond what has been previously described in the literature. CONCLUSION: EIP is commonly used as a tendon transfer for extensor pollicis longus rupture. Few anatomic variants of EIP have been reported in the literature, but such variants should be considered because of their consequences to the success of tendon transfer and potential implications for diagnosis of an otherwise unexplained mass of the wrist.

Early and prolonged opportunities to practice suturing increases medical student comfort with suturing during clerkships: Suturing during cadaver dissection.

Medical students are expected to perform common procedures such as suturing on patients during their third-year clerkships. However, these experiences are often viewed by medical students as stressors rather than opportunities for learning. The source of this stress is the lack of instruction on common procedures prior to being asked to observe or perform the procedure on a patient. First-time exposures to procedures in stressful environments may result in decreased confidence in medical students and decrease the frequency with which they perform these procedures in the future. The authors sought to change this paradigm by: (1) introducing a suturing module to first-year medical students in the context of the anatomy dissection laboratory and (2) measuring its effects on student attitudes and behavior over the course of their third-year clerkships when they encounter patients. The authors found that early and prolonged introduction to suturing was associated with increased student confidence relative to suturing a patient. Participation in the suturing module was associated with increased student confidence in identifying suturing instruments (P < 0.001) and suturing patients (P = 0.013). Further it positively affected their behavior as demonstrated by increased performance of suturing events from students exposed to the suturing module. (P < 0.001) This study demonstrates that early and prolonged opportunities to practice a procedural skill in a low-stress environment increases student confidence during patient interactions and alters student behavior.

Vertical incision intraoral silicone chin augmentation.

OBJECTIVE: Solid silicone augmentation mentoplasty is a common procedure with consistent aesthetic results in properly selected patients. While many plastic surgeons employ the external approach, the intraoral method affords excellent aesthetic outcomes while avoiding an external scar. This is the largest series in the literature describing the midline intraoral incision approach with minimal disruption of soft tissues. STUDY DESIGN: Case series. SETTING: Academic medical center. SUBJECTS AND METHODS: One hundred twenty-five patients underwent chin augmentation with solid silicone implants between 2004 and 2010. Among these implants, 105 were placed transorally. Eighty-five patients were followed for at least 1 year. Demographic information, indications, patient satisfaction questionnaire results, and complications were recorded. RESULTS: All implants yielded satisfactory results with no displacement, infection, tissue reaction, lower lip incompetence, mental nerve injury, or intraoral implant contamination. Two cases of superficial mucosal irritation at the suture site were observed and resolved without consequence. Symmetry, projection, and overall balance of facial components were excellent. Although all patients were satisfied with the functional and aesthetic results, 20% stated they would like further augmentation. Patients were extremely satisfied with the lack of an external scar. CONCLUSIONS: Based on our series, the intraoral technique with a midline incision avoiding disruption of the mentalis muscle is recommended for its ease, simplicity, patient satisfaction, low complication rate, and circumvention of an external scar. The external approach should be considered in cases that require a very large implant.

Nasal dorsal augmentation with silicone implants.

Silicone rubber has been used safely and effectively for facial augmentation for nearly 5 decades in eastern Asia. We have used silicone rubber nasal implants in primary ethnic rhinoplasty and have found consistent and long-lasting results with low complication rates. Silicone dorsal nasal augmentation in primary rhinoplasty avoids donor site morbidity and implant resorption as seen with autogenous implants. Silicone nasal implants have a low extrusion and infection rate. In the appropriate patient with proper placement, silicone nasal implant is nearly the ideal implant material.
