  • Gordon Sasaki, M.D., "Release-Wire Subcision and Fills for Wrinkles, Folds, and Scars; A Comparison of Results After Surgical Procedures and Fills", Aesthetic Surgery Journal, July/August 2008.  Abstract     Background:  Because of the fixed attachments or muscle-SMAS insertions to the undersurface of wrinkle lines, folds and retracted scars, the use of fills alone has resulted in unpredictable and unsatisfactory improvements.   Objectives: The use of a wire dissector to completely release these attachments and accompanied with an immediate fill and/or an adjacent aesthetic surgical procedure may optimize the final results.   Methods: The subcision wire was positioned under various wrinkles, folds and scars in a triangulated outline and then zig-zagged to uniformly release any subdermal attachments. A number of depressions underwent only a ReleaseWire procedure (Category 1). The Category 2 group was filled immediately with a strip of autogenous filler or a xenograft material. The Category 3 group combined the ReleaseWire procedure without fill and an adjacent aesthetic procedure. Category 4 sites involved the ReleaseWire procedure, fill and an adjacent aesthetic surgical procedure. The benefits of each of the added  procedures on ReleaseWire subcisioned sites were rated with a photographic Wrinkle/Fold Assessment Scale (mean ± SD) by two masked evaluators at least after 6 months. Assessment was based on a Quartile Grading Scale: 0 = less than 25%, 1 = 25-50%, 2 = 51-75%, and 3 = greater than 76% improvement.   Results:  Eighty-five patients experienced 338 ReleaseWire procedures at eight facial sites, one posterior neck site and four sites of thigh cellulite. The longest follow-up was 1.5 years, with a mean of 6.3 months. The cumulative Quartile Grading Scale was recorded as: Category 1 (1 ± 1.5 SD); Category 2 (3.1 ±0.1 SD); Category 3 (2.5 ± 0.2); and Category 4 (3.6 ± 0.2). When fills were employed as spacers under the release tracts in Category 2 and 4 sites, strips of SMAS and dermis and microfat droplets were the favored fills in the areas of the nasolabial and marionette folds because of the capacity of the graft’s volume and tissue acceptance. For shallower depressions, such as the glabellar frown lines and crow’s feet, strips of deep temporal fascia or muscle were more effective. Complications after ReleaseWire procedures with or without fill were few and transient.   Conclusions: The use of this type of subcision for resistant wrinkles, folds or scars can result in a satisfactory outcome when use as a solitary procedure with minimal complications. Enhancement of the surgical result may be further optimized with the immediate addition into the released tract. An adjacent aesthetic surgical procedure that impacts at the subcised site may provide additional benefit to the site but not as much as observed with the usage of an immediate fill. Autogenous fills that are substantitive provide longer lasting effects because of volume and tissue acceptance.   (07/2008)

Abstract   In recent years, a number of designed suspension sutures have been rapidly introduced into clinical practices. The benefits, deficiencies and limitations of this applied emerging technology are defined by clinical experiences. This study compares the Holding Tension, Slippage Tension and Pull-out Tension for each of eight suspension suture systems randomly positioned in the midface soft tissue in four fresh-frozen cadaver heads. Photo micrografts of the fixation sites (barbs, cones, knots, pulleys) on the extracted sutures were examined and compared to their pre-insertion state. The results of this study clarifies our understanding of the safety, benefits and limitations of these systems.

  • Gordon Sasaki, M.D., Barbara Tucker, RN, Margaret Gaston, "Clinical Parameters for Predicting Efficacy and Safety with Non-Ablative Monopolar Radiofrequency Treatments to Forehead, Face and Neck", Aesthetic Surgery Journal, 2007. ABSTRACT   Background: Patient selection is key to obtaining a successful outcome after non-ablative monopolar radiofrequency treatments to the forehead, face and neck. The purpose of this study was to discover at baseline any predictors from patient demographics, skin and fat characteristics, measurable degrees of tissue mobility and photoaging that may be useful to predict a positive result under a standardized treatment algorithm.   Methods: Twenty-five patients (22 females, 3 males; average age 52.3 years) were selected randomly for NMRF treatments (2 non-overlapping passes, additional passes for vectored contraction and contouring) between 350-450 firings with 1.5 cm tips to the forehead, periorbitum, face and upper neck. Patients were evaluated at baseline and followed for outcomes beyond 1 year by a number of quantitative assessments.   Results: At baseline, 3, 6 and l2 months, measurements of skin thickness, subcutaneous fat depth, tissue mobility, and wrinkle and fold depth were obtained at nine different reference sites on each patient. Nineteen patients (76%), who progressively responded to NMRF energy over 12 months, were observed at baseline to have a global mobility score (mean ± S.D.) of 3.4 ± 0.27 mm; six patients, who were assessed to be non-responders over l year of evaluation, began with more tissue laxity and exhibited at baseline a larger global mobility score (mean ± S.D.) of 4.4 ± 0.60 mm. Other factors, that were more likely to be associated with a positive response to NMRF treatment, included minimal degrees of photoaging and shallower wrinkle/fold development. The variables of skin thickness and fat depth did not play significant roles in predicting positive responses to treatment. Side effects and complications were minimal throughout the study. Conclusions:   This study represents one of the first investigations that attempts to identify systematically objective baseline parameters that are more likely to be associated with positive responses to NMRF treatments to the forehead, face and neck. Longer follow-ups of our patients and further studies will be required to verify our preliminary findings.
