External ultrasonic lipoplasty: an effective method of fat removal and skin shrinkage.

External ultrasonic lipoplasty is an effective method for the removal of localized fat and the fat due to moderate obesity. The ultrasound is externally applied and transmitted through the skin surface. The acoustic waves are selectively absorbed by previously injected tumescent fluid and fat. It is the combination of this acoustic wave and ultrasound-induced fluid streaming that facilitates fat removal. Multiple, 2.5- to 3.7-mm incisions are made, through which standard thin (2.3 to 3.5 mm) suction lipectomy cannulae are used to aspirate the emulsified fat and oil. A major advantage of this procedure is that superficial subdermal liposuction can be used safely, which enhances the thoroughness of fat removal and the contraction of the overlying skin. A total of 160 consecutive patients successfully underwent this procedure. Recovery was rapid, and patients returned to full activities within 24 to 48 hours. The skin remained soft, with minimal to no bruising throughout the entire postoperative period. The problems seen with internal ultrasonic liposuction, such as end hits and skin burns, were avoided. The large incisions required for internal ultrasound liposuction were not necessary. Previous models of externally applied ultrasound support current observations of the safety of external ultrasound lipoplasty. Only one small seroma was seen. External ultrasound lipoplasty is a safe, effective, and low-cost method of ultrasound-assisted removal of localized fat and the fat due to moderate obesity. Physician and patient satisfaction is high.

Temporary tarsorrhaphy suture to prevent or treat scleral show and ectropion secondary to laser resurfacing or laser blepharoplasty.

The temporary tarsorrhaphy suture is introduced as a simple effective technique to prevent scleral show or ectropion secondary to laser skin resurfacing or laser blepharoplasty. In all but severe cases of prior existing scleral show or ectropion, the temporary tarsorrhaphy suture has been completely effective. It is also successfully used to prevent scleral show and ectropion for patients with poor lid snap and loss of elasticity of the lower eyelid at the time of laser skin resurfacing and blepharoplasty. A 5-0 Prolene suture is placed through the gray line to approximate the upper and lower eyelids and is left in place for 5 days. This supports the lower eyelid during the critical period of dermal and epidermal regeneration and during the formation of new collagen and elastin.

Long-term histologic effects of the CO2 laser.

The long-term histologic effects of CO2 laser resurfacing previously were unknown. Prior investigations have clearly defined the photothermal effect. Collagen shrinkage as a reaction to increased tissue temperature between 60 and 70 degrees C has also been previously described. Twenty-two patients completed a 1-year study in which biopsy specimens from the upper lip were taken preoperatively and 6 weeks, 6 months, and 1 year after CO2 laser resurfacing. Trichrome stains and Verhoeff-van Gieson stains were used to demonstrate tissue collagen and tissue elastin. Neocollagenesis beginning at 6 weeks and progressively increasing at 6 months and 1 year was clearly demonstrated. Neoelastogenesis showed significant increases at 6 months and 1 year. It is hypothesized that the additive effects of initial collagen shrinkage and the long-term effect of neocollagenesis and neoelastogenesis are the significant factors contributing to the long-lasting and excellent results of CO2 laser skin resurfacing.

The subperiosteal endoscopic laser forehead (SELF) lift.

The subperiosteal endoscopic laser forehead lift is shown to be an effective tool for plastic surgeons. By combining the use of the carbon dioxide laser with the already established technique of endoscopic forehead lift, improved results are achieved. The technique of endoscopic forehead lifting lends itself to new advancements in laser technology. Through the use of flexible laser wave guides or rigid laser extensions, the efficiency and safety of the procedure is proven. Skin excision and fixation have not been necessary. Twenty patients have undergone this procedure successfully; long-lasting results are demonstrated.

Full face and neck laser skin resurfacing.

Since the inception of laser skin resurfacing for the removal of facial rhytides, laser surgeons have avoided laser resurfacing of the neck. The purpose of this paper is to demonstrate that the accuracy and precision of the Ultrapulse carbon dioxide laser allows the laser surgeon to safely laser skin resurface the neck as well as the full face. This series includes 40 patients who have undergone laser skin resurfacing of the neck at the time of full-face laser skin resurfacing. Three subgroups are defined. Thick-skinned patients, thin-skinned patients, and patients who otherwise would have medical contraindications to face and neck lift are included in this study group. Patients between the ages of 40 and 60 who do not have a lot of excessive neck skin or prominent platysma bands are candidates for full face and neck laser skin resurfacing. Successful tightening for thick-skinned patients occurs by using 300 mJ at 60 W. a density of 6, and one pass. For thinner-skinned patients, the upper half of the neck is treated with 300 mJ, 60 W, a density of 6, and one pass. The lower half of the neck in these patients is treated with 125 mJ and 20 W, a density of 6, and one pass. In some patients who otherwise have medical contraindications for face and neck lift, the laser may be an indicated procedure because there is minimal bruising, lack of bleeding, minimal edema, minimal to absent use of adrenaline, and nonincisional surgery with a speedy recovery. The Ultrapulse laser delivers high energy with high speed, precision, and control. Therefore, the laser surgeon can successfully laser skin resurface the neck at the time of full face laser skin resurfacing. Immediate tightening of the face and neck, from the photothermal effect, and the neocollagenesis effectively tighten the neck in the properly selected patient.

Lasers in aesthetic surgery.

Lasers are now in their third decade of medical application. The use for aesthetic surgery is relative new. Multiple attempts to use lasers in cosmetic surgery, in the past, resulted in less than desirable results. The current generation of lasers now has multiple applications in aesthetic surgery, with much success in tattoo removal, skin resurfacing, and cosmetic procedures. The plastic surgeon, with an augmented armamentarium, is now able to solve old problems and face new challenges. Careful attention to the fine details will allow the surgeon to avoid problems and complications when using the laser for aesthetic surgery. The ease of using the laser, speed of the procedure, patient satisfaction, and the minimal amount of potential complications all encourage the plastic surgeon to utilize the laser for aesthetic surgery.

Correction of saddlebag deformity of the lower eyelids by superficial suction lipectomy.

A simple, quick, and safe method for the correction of eyelid saddlebag deformity is presented. Past techniques involved intricate muscle transposition flaps and extensive dissection. Anatomic dissection clearly demonstrates that the saddlebag deformity is caused by an excess of subcutaneous fat in a well-defined space similar to the fat pads of the upper and lower eyelids. This newly described fat pad lies over the preorbital fibers of the orbicularis oculi muscle and at times extends into the malar area. The technique of superficial suction lipectomy for the removal of eyelid saddlebag deformity is simple and done with local anesthesia on an outpatient basis. Results in multiple patients with follow-up ranging from 1 to 7 years are presented.

A new cannula for suction removal of parenchymal tissue of gynecomastia.

Previous criticism about suction lipectomy for the correction of gynecomastia was related to the cannulae available at the time. With the improved design and tensile strength of the cannula, gynecomastia can be more easily corrected. The procedure can be completed with more control of the final contour and with fewer complications. The patient's satisfaction is also increased by the brief convalescence and immediate return to normal lifestyle.

Gynecomastia: suction lipectomy as a contemporary solution.

Suction lipectomy is adapted for the correction of gynecomastia. Previous attempts using suction lipectomy for gynecomastia still required the use of sharp dissection for removal of the glandular breast tissue as well as excision of redundant skin. With this new technique, gynecomastia is corrected solely with the use of suction lipectomy. The technique is successful if the gynecomastia is due to excess fat or parenchymal hypertrophy. A 7-mm cannula is inserted first, to remove the adipose tissue. Then a 2.4-mm cannula is used to remove the glandular and ductal tissue. The 7-mm cannula is then reinserted to remove subareolar parenchyma and to make final contour adjustments. The surrounding subcutaneous tissue is easily undermined to avoid a saucer deformity and to allow for skin contraction. Patients return to full activities in 48 hours. A compressive garment is worn for 4 to 6 weeks. The results of 10 patients are discussed.

Venous drainage of the lateral trapezius musculocutaneous island flap.

The transverse cervical artery (TCA) and the transverse cervical vein (TCV) form the dominant vascular pedicle for the lateral trapezius musculocutaneous island flap. The experience of others described previously leaves little doubt as to the reliability of this flap. The anatomy of the TCA is such that we have encountered no difficulty in maintaining arterial flow through wide arcs of flap transfer. The TCV, on the other hand, is variable, and maintaining venous drainage may be difficult. After reviewing the available literature and finding little detailed guidance, we studied the anatomy of the TCV in nine patients undergoing surgery and in six fresh cadavers.

Sudden hearing loss in divers and fliers.

Many papers have been written about sudden sensory hearing loss and the effect of barotrauma on the inner ear. Fistulae of the round and oval window membranes have been implicated in the great majority of these cases. It has usually been recommended that the patient be treated with conservative therapy, such as bed rest, for a period of as long as 30 days and that the final hearing results are as good or better than those that have been surgically explored and corrected. In our experience immediate surgical exploration and correction of sudden severe or profound sensorineural deafness in the diver or flier is absolutely essential and the excellent results of hearing improvement in this select group certainly corroborates this theory. Other cases with the hearing loss limited to the high frequencies most notably have tinnitus and surgical exploration does not improve the hearing but may improve vertigo if present. Numerous cases are presented to support these supositions.
