Endoscopic intracorporal abdominoplasty: a review of 85 cases.

The specialty of plastic surgery has witnessed an explosion of novel procedures with the advent of endoscopy. Surgeons are making more aggressive attempts to reduce the length of scars and subsequent morbidity associated with traditional "open" procedures. Our purpose is to present a new technique of endoscopic abdominoplasty that has largely replaced traditional "full open" techniques at our institution. Since 1985, 85 patients have undergone a procedure that we call the endoscopic intracorporal abdominoplasty. This technique combines traditional abdominal wall liposuction with endoscopic intracorporal plication of the rectus fascia by using a series of horizontal mattress sutures. The procedure is performed using three 1-cm incisions and a series of midline and lateral skin nicks. These 85 patients were compared with 25 patients who underwent traditional open abdominoplasty with anterior plication of the rectus fascia. Average length of surgery was 127 minutes compared to 149 minutes with the open techniques. Length of hospitalization at our institution was 1 postoperative day compared to an average of 3 days with open techniques. No drains were used with the endoscopic techniques, and all of the open procedures had two drains placed. The perioperative rate of morbidity for the intracorporal abdominoplasty was 15 percent (13 of 85 patients) and with the open abdominoplasty cases it was 24 percent (6 of 25 patients). Our conclusion is that the endoscopic intracorporal abdominoplasty reduces operative scars and effectively plicates the rectus fascia, thereby reducing abdominal wall laxity. It has a rate of morbidity in a skilled laparoscopist's hands no greater than with traditional open abdominoplasty.

Precautions in warming light therapy as an adjuvant to postoperative flap care.

Warming lights, circulating-water blankets, space heaters, and the Bair Hugger are used by surgeons in the perioperative period to maintain a patients core body temperature. Warming lights in particular are often used by plastic surgeons to augment the postoperative vasodilatation of reconstructive flaps by increasing the ambient temperature of the area around the flap. A review of the literature fails to elucidate even anecdotal experience regarding the actual intensity of thermal energy directly imparted to tissues from these modalities with respect to distance. The purpose of our study was to quantify actual tissue temperatures generated, as a function of distance, with the Emerson warming light. Our interest in this is a result of a full-thickness burn which occurred to a portion of a pedicled TRAM flap used for breast reconstruction when a warming light was inadvertently positioned, during the course of the first postoperative night, at a distance less than that recommended by the manufacturer. A biological model was created simulating a sympathectomized flap and the temperature curves generated by Emerson warming lights were recorded by calibrated glass bulb thermometers at 15 min intervals for distances of 32 and 71 cm using both focused and defocused light beams. The distance of 32 cm was used as a parameter as it was the distance noted between the patient and the warming light when the TRAM flap burn occurred. Temperatures obtained at a distance of 32 cm rose to 120 degrees F (48.8 degrees C) within 30 min for the focused beam and 118 degrees F (48 degrees C) after 1 h for the defocused beam. This exceeds the temperature at which tissue necrosis is known to occur (111.2 degrees F/44 degrees C). However, temperatures obtained at 71 cm for the focused and defocused beams plateaued at 93.2 and 96.8 degrees F (34 and 36 degrees C) respectively, which is well within physiologic limits and below the temperature resulting in tissue necrosis. Our conclusion is that warming lights can be successfully used as a safe adjuvant in order to optimize flap vasodilatation without compromising the thermal threshold of tissue damage if maintained at the manufacturer's minimum recommended distance of 71 cm. If this source of thermal energy is used, however, strict precautions and nursing guidelines must be instituted to maintain this minimum distance parameter and prevent patient morbidity.

Ultrasound-assisted lipoplasty learning curve.

Ultrasound-assisted lipoplasty is currently one of the newest techniques available to aesthetic surgeons. Plastic surgery organizations have undertaken the challenge of teaching proper ultrasound techniques and protocols via a series of ultrasound task force credentialing courses. The purpose of this article is to share our learning curve experiences with this technique. Our intent is to aid others with their learning curve so that more predictable early results are obtained. Between April 25, 1997, and July 15, 1997, a total of 84 patients comprising 150 anatomic sites underwent ultrasound-assisted lipoplasty at Naval Medical Center, Portsmouth, VA. These procedures were performed by four different plastic surgeons, with most cases (n=59) and procedures (n=114) performed by the senior author (M.L.Z.). The morbidity involved with these cases was early and consisted of three seromas and one focal area of iatrogenic epidermal abrasion. Follow-up has ranged from 7 to 10 months; there are no dissatisfied patients nor any patients currently scheduled for secondary corrective procedures. Our conclusions are (1) ultrasound-assisted lipoplasty is a safe and efficacious procedure; (2) there is a steep learning curve to the procedure, which we believe involves a minimum of 30 patients and requires great attention to detail in terms of volume of infused tumescent solution, and ultrasonic aspiration times; and (3) volume for volume, morbidity associated with this procedure should be no greater than with traditional tumescent lipoplasty.

Breast reduction under intravenous sedation: a review of 50 cases.

Breast reduction is a surgical procedure most commonly performed on an inpatient basis under general anesthesia. In the current climate of health care reform, we must evaluate such procedures to determine if there are alternate, less expensive, but equally safe means to perform them. Our purpose is to present our experience with 50 bilateral breast reductions performed under local anesthesia with intravenous sedation between October of 1991 and October of 1994. We have excluded bilateral reductions under 500 gm total, unilateral reductions, mastopexies, and gynecomastia procedures. Patients were sedated with intravenous Versed and fentanyl and a local solution consisting of marcaine, lidocaine, and 1:2000,000 epinephrine. Intercostal blocks were not used routinely. Monitoring and sedation were performed by nonanesthesia personnel in 49 patients. There were no complications relating to the sedation or to the local solution. All reductions were performed by the inferior pedicle technique. The average patient age was 28.0 years (20 to 67 years). The total breast tissue resected was 1372 gm (516 to 2948 gm), with 33 patients having resections greater than 1000 gm. Operative times averaged 3 hours (115 to 275 minutes). Forty-nine of the 50 patients tolerated the procedure with little or no recall. Twenty-eight patients were discharged on the same day as admission. One patient recalled some significant discomfort during parts of the procedure. All stated that they would again have the procedure performed under local anesthesia with intravenous sedation. Our conclusions are as follows: (1) Breast reduction can be performed safely and comfortably under local anesthesia with intravenous sedation. (2) Patients should be chosen on their acceptability as intravenous sedation candidates and not with regard to the amount of breast tissue removed. (3) There will be a subset of patients who can be discharged on the same day.

Cryoglobulinemia: dilemma for the reconstructive surgeon.

Cryoglobulinemia was initially noted to occur predominantly in patients with myeloma, but it is now being detected in a growing number of infectious, collagen-vascular, and lymphoproliferative disorders. Two patients with leg ulcers due to cryoglobulinemia are presented. The reconstructive surgeon should consider cryoglobulinemia in the differential diagnosis of skin necrosis that is refractory to conventional therapy, since they may be consulted for wound management. In the vast majority of instances, the patient will be referred with a diagnosis of cryoglobulinemia having already been established. In other circumstances, patients may present to the plastic surgeon with no known history of cryoglobulinemia. The informed reconstructive surgeon can make the diagnosis on the basis of clinical findings. Combination therapy (corticosteroid, immunosuppression, and plasmapheresis) may be of use when areas of skin necrosis, typically in the form of leg ulcers, fail to heal with routine measures.

Pilot study analysis of the histologic and bacteriologic effects of occlusive dressings in chemosurgical peel using a minipig model.

The histologic changes associated with chemosurgery are well documented, but the data concerning the effects of occlusive dressings (adhesive tape, gauze, or ointments) is largely anecdotal. Wide differences of opinion exist as to the best method of phenol application and postpeel wound care regimen. Using a Yucatan minipig as our animal model, we studied the histologic and bacteriologic differences that various commonly used occlusive dressings have upon the initial burn depth and the subsequent healing of peeled skin. We also compared chemical peel with dermabrasion and chemabrasion. Our results showed to statistical difference in peel depth between "wet" versus "moist" phenol application or between occluded versus nonoccluded dressings. Based upon this animal model, we recommend that phenol solutions be applied moist rather than wet and that an occlusive dressing other than adhesive tape be used and maintained for a minimum of four days.

The fourth option: a novel approach to lower-lid blepharoplasty.

Three basic surgical techniques exist for lower-lid blepharoplasty: (1) the skin flap, (2) the transconjunctival approach, and (3) the skin-muscle flap. Each addresses the problems of excessive skin, muscle, and infraorbital fat either alone or in combination. None of these procedures will correct fine wrinkles. In fact, in some patients the lower-lid wrinkling appears far worse after fat removal. We describe a "fourth option" to lower-lid blepharoplasty which corrects the problem of fine wrinkling, periorbital fat herniation, and mild skin excess. For these patients, we remove the fat through a transconjunctival approach and peel the lower lid using full-strength Baker's phenol solution. To date, we have performed this procedure in 17 patients with excellent results. There have been no complications. Our longest followup is 30 months. This procedure is indicated for patients with both excess infraorbital fat and lower-lid skin with associated fine wrinkling. Only the experienced surgeon should attempt this procedure. Caution should be exercised with patients who have previously undergone blepharoplasty as severe ectropion has been reported with chemical peel around the eyelids. Lower-lid chemical peel after a modified skin-muscle flap has been described, but we believe that peeling after a transconjunctival approach is safer. We feel that with more knowledge and experience using the "fourth option" of lower-lid blepharoplasty, it will become the procedure of choice for select patients.

Criteria for the forehead lift.

We have developed clinically useful measurements to assist the surgeon in deciding when to do the forehead lift and where to place the incision. Also, we have reviewed our experience over the past decade and discuss the four categories and applications of forehead lifts. We use three indications for forehead lift: ptosis, creases, and previous facelift (PCP). There are four basic surgical techniques applicable to the upper face: (1) direct browlift, (2) midforehead crease incision, (3) prehairline incision, and (4) posthairline incision. We determined more accurate guidelines from measurements taken on 50 volunteers, as well as patients seeking a facelift. The line of measurement in a vertical plane extends from the midpupil to the top of the eyebrow and up to the hairline. We have found that the normal distance from the midpupil to the upper edge of the eyebrow on average is 2.5 cm and that the distance from the upper edge of the eyebrow to the hairline is approximately 5 cm on average. If the distance from pupil to brow is less than 2.5 cm, then the patient may benefit from a forehead lift. If the distance from brow to hairline is less than 5 cm, then we use a posthairline incision in females. If this same distance is greater than 5 cm in females, we advise the prehairline incision. In male patients we strongly consider direct crease incision. The direct browlift is reserved for minimal ptosis, asymmetry, or patients who wish a minimal procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

Anterior nasal stenosis secondary to accessory nasal bones.

Choanal atresia may result from a posterior or anterior obstruction of the airway. Treatment is predicated on an accurate identification of the underlying pathological condition by means of physical examination, fluoroscopy, and computed tomographic scan. Expeditious surgical management after appropriate diagnosis appears to result in effective relief of the obstruction.

The value of tear film breakup and Schirmer's tests in preoperative blepharoplasty evaluation.

The results of tear film breakup (BUT) and Schirmer's I and II tests were retrospectively analyzed on 146 patients undergoing elective blepharoplasty over a 41-month period. These tests were evaluated in conjunction with ocular history, orbital and periorbital anatomy, and Bell's phenomenon in order to determine their value, if any, in identifying patients at risk of developing a post-blepharoplasty dry eye complication. One-hundred and six patients (73 percent) had test results that were within normal limits, and two of these patients (1.9 percent) complained postoperatively of a transient gritty or burning sensation. Forty patients (27 percent) had abnormal results to one, two, or all three tests, and two of these patients (5 percent) also complained postoperatively of a transient gritty or burning sensation. These four symptomatic patients all had preoperative dry eye histories and abnormal orbital and periorbital anatomy. When analyzed alone, an abnormal tear film breakup (BUT) or Schirmer's test was not a good predictor of possible postblepharoplasty dry eye complications. An abnormal preoperative ocular history or abnormal orbital and periorbital anatomy proved to be the best predictor for the possible development of a postblepharoplasty dry eye complication.
