OnabotulinumtoxinA for the treatment of a "gummy smile".

BACKGROUND: Excessive gingival display, or a "gummy smile," is defined as 2 mm or more of gingival exposure upon smiling. Such excessive gingival exposure can be aesthetically unappealing to patients. One factor that contributes to a gummy smile is hyperfunctional lip elevator muscles. OBJECTIVES: The authors evaluate onabotulinumtoxinA as a safe and minimally invasive treatment for a gummy smile. METHODS: In this prospective study, 14 patients (13 women, 1 man) underwent pretreatment photographs and measurements, followed by bilateral injection of onabotulinumtoxinA into their lip elevator muscles. All patients selected for the study had more than 2mm of gingival show and were classified as having a "cuspid smile," where action of all elevator muscles raised the upper lip- like a window shade-to expose the upper teeth and gingival scaffold; these patients were thought to have a better chance for a more superior result. Repeat measurements and photographs were collected at 2 weeks and 3 months. Patient-reported outcomes were collected at 2 weeks, and data were compared to determine the correlative relationship. RESULTS: An average of 5 units (range, 4-6 U) of onabotulinumtoxinA were injected into 3 sites bilaterally. The average preinjection gingival show over the central incisors and canines were 4.89 mm and 4.25 mm, respectively. Postinjection gingival show decreased to an average of 0.75 mm (85% improvement) and 0.74 mm (83% improvement) over the central incisors and canines, respectively. Average follow-up time was 12.6 days. One patient felt the resulting smile was unattractive and opted not to undergo repeat injections, while all other study participants experienced no negative effects and wished to undergo repeat treatment. CONCLUSIONS: As treatment for a "gummy smile," onabotulinumtoxinA provides an effective, minimally invasive, and safe therapy. This treatment option can lead to significant improvement in smile aesthetics with high patient satisfaction. LEVEL OF EVIDENCE: 3.

Prosthesis salvage in breast reconstruction patients with periprosthetic infection and exposure.

BACKGROUND: Breast prosthesis reconstruction continues to be the most common form of breast reconstruction, and infection and exposure remain major concerns for patients and surgeons. METHODS: A retrospective review was performed of patients who underwent attempted implant salvage between 2002 and 2008 by a single surgeon according to a single protocol. Analyzed data include detailed patient demographics, clinical and laboratory findings, and outcomes. RESULTS: Sixty patients were identified who had been taken to the operating room secondary to infection and/or exposure of a breast prosthesis. Seventeen underwent removal of the prosthesis without attempted salvage and 43 patients underwent attempted salvage. Successful attempted salvage occurred in 76.7 percent of cases, with a mean follow-up of 18.4 months (range, 1 to 60 months). Staphylococcus epidermidis led to a statistically higher rate of failed salvage (25 percent versus 0 percent, p = 0.04). Of the 33 patients who had successful salvage of the prosthesis, two developed capsular contracture (6 percent). CONCLUSIONS: Intervention should be prompt and aggressive, and should implement a combination of surgical and antimicrobial therapies. The data from the authors' results provide additional tools for patient selection and treatment, and offer a simplified management protocol for breast reconstruction patients with infected and/or exposed breast prostheses. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Drug abuse in plastic surgery patients: optimizing detection and minimizing complications.

Drugs of abuse present numerous challenges to plastic surgeons, and detection remains difficult. With rates of drug abuse and misuse on the rise, clinicians must remain especially attentive to drug abusers' verbal and nonverbal cues, and be familiar with treating perioperative complications if they arise. Informed deductions regarding drug abuse can enable a plastic surgeon to identify drug abuse, minimize complications, and optimize patient care.
