Prevention of temporal alopecia following rhytidectomy: the prophylactic use of minoxidil. A study of 60 patients.

BACKGROUND: Temporal hair loss that results from traumatized hair follicles following rhytidectomy is an unsightly complication that can distress both the patient and the operating surgeon. Topical minoxidil is a proven therapy for androgenic alopecia and female senile alopecia. It has also been found to be useful in preventing the hair loss that commonly follows hair transplantation. OBJECTIVE: To analyze through a retrospective study the effect of topical minoxidil on the incidence of temporal hair loss following facelift procedures. To our knowledge this is the first study to investigate the role of minoxidil in preventing post-rhytidectomy temporal alopecia. METHODS: The charts of 60 women with a mean age of 58 years who underwent primary cervicofacial rhytidectomy were studied. Either a standard SMAS/flap technique or pliation was done in all cases. Each patient received either 2% or 5% topical minoxidil for 2 weeks before surgery and for 4 weeks after surgery, with a 5-day break period beginning on the day of surgery. Patients were monitored for complications immediately postoperatively and in 3-6 months of follow-up. RESULTS: Almost 80% of the patients underwent SMAS/flap procedures. Transient temporal alopecia was noted in only one patient, 6 weeks after discontinuing minoxidil. This resolved within 4 weeks of its reintroduction. The only other complications noted included minor hematomas (3.3%), skin slough/infection (1.7%), minor transient and localized edema (8.3%), minor ecchymosis (1.7%), a unilateral neuropraxia of the buccal nerve lasting 3 months (1.7%), and a minor temporary unilateral skin depression (1.7%). Side effects of minoxidil were not observed. CONCLUSION: On comparing our findings to results of larger rhytidectomy series in which minoxidil was not used prophylactically, and our experience before using minoxidil, we conclude that minoxidil plays a role in effectively preventing the temporal hair loss that occurs following primary cervicofacial rhytidectomies. We also found that minoxidil did not negatively impact on the risk of hematoma formation, skin necrosis, edema, or ecchymosis. Side effects of minoxidil did not present a problem.

Treatment of face veins with a cryogen spray variable pulse width 1064 nm Nd:YAG Laser: a prospective study of 17 patients.

BACKGROUND: Through the 1990s laser treatment of leg veins has been a challenge. Newer, longer wavelength lasers with variable pulse width have shown promising results for both telangiectasia and reticular leg veins. Experience with these lasers for treatment of facial telangiectasia and periorbital reticular veins is scant. OBJECTIVE: To our knowledge this is the first prospective study to evaluate a variable pulse width, cryogen spray-equipped 1064 nm Nd:YAG laser for the treatment of facial telangiectasia and larger periorbital reticular veins. METHODS: Seventeen volunteers, ages 32-67 years, skin types I-IV, with facial telangiectasia and reticular periorbital/temporal veins were treated once with the Nd:YAG laser at fluences of 125-150 J/cm2 with a 6 mm spot size and pulse widths of 25 msec for small vessels and 75-100 msec for reticular veins. Patients were examined 1 week and 1 month after the treatment. Pre- and posttreatment 35mm photographs were taken. Improvement was judged by two experienced physicians, both visually on patients and by comparison of pre- and posttreatment photographs. Results were graded as percent resolution, in five groups: 0%, 0-25%, 25-50%, 50-75%, and 75-100%. RESULTS: All 17 patients completed the study. Thirty-two sites were treated (24 cheek, nose, and chin telangiectases, and 8 periorbital reticular veins). Greater than 75% improvement was observed in 97% of the treated sites. Greater than 50% improvement was observed in 100% of the treated sites. Notably, 100% of the facial reticular veins treated have essentially 100% resolution. Pain during treatment was variably perceived by patients, but occasionally sufficient for patients to express reservations about additional future treatment. Transient erythema and edema were common, but fine crusting was rare. Small areas of purpura were also quite rare. CONCLUSION: The cryogen spray-equipped 1064 nm Nd:YAG laser was remarkably effective and safe for skin type I-IV patients. It is an excellent tool for treatment of facial telangiectasia with minimal risk of purpura. For the first time we appear to have a simple, safe, and effective treatment for 1-2 mm periorbital reticular veins. The use of topical anesthesia may be needed for some patients.
