Current concepts in nonablative radiofrequency rejuvenation of the lower face and neck.

With the multitude of treatment options and emerging technology available for rejuvenation of the lower face and neck, it is often difficult to determine which specific treatment would benefit an individual patient. Monopolar radiofrequency (MRF) nonablative skin rejuvenation is a promising new procedure that is utilized to tighten and contour nonsurgically mild to moderate laxity of the skin of the lower face and neck in patients without significant underlying structural ptosis. In these selected patients and others who wish to avoid surgical treatment modalities, MRF treatment offers a noninvasive method of tightening skin and soft tissue, causing softening of the nasolabial lines, tightening of the jowl, and improving the definition of the cervicomental angle, all without significant recovery time or complications. Further development of MRF technology and refinement of treatment protocols may allow even greater tightening of the skin and more dramatic modulation of underlying deeper structures, making the treatment more universally applicable for patients desiring facial rejuvenation.

Microcoblation: nonablative skin rejuvenation.

Microcoblation is the application of a controlled high-energy plasma field to intact aging skin. The treatment is nonablative and yields predictable, reversible histological changes in the epidermis, which result in skin rejuvenation. Recovery time and side effects are minimal. Although the mechanism of action is different, patient satisfaction with microcoblation compares very favorably with microdermabrasion, the traditional method of superficial skin rejuvenation.

Clinical evaluation of non-ablative radiofrequency facial rejuvenation.

OBJECTIVE: To evaluate the clinical efficacy of non-ablative cutaneous radiofrequency (RF) facial rejuvenation. DESIGN: Prospective study with longitudinal follow-up of a validation cohort set in an urban, private practice of an ambulatory facial plastic surgery center in southern California. METHODS: A consecutive sample was enrolled of 35 healthy adults with moderate facial aging, manifested by skin laxity, rhytids, and ptosis (brow, midface, jowls). Following intravenous sedation anesthesia, the study area was treated with 115-144 J/cm2 using the non-ablative RF device (ThermaCool TC). The main outcome measures were the objective measurement of brow height, investigator evaluation of skin parameters, a patient satisfaction questionnaire, and standardized photography, at fixed time intervals. RESULTS: At 12 weeks, a statistically significant increase in mean vertical brow height of 1.6-2.4 mm was observed in patients treated exclusively with the RF device (p<0.0001). All skin parameters (laxity, wrinkles, clarity, pore size) were improved. Complications and side effects were minimal. Patients were uniformly satisfied. CONCLUSIONS: The ThermaCool TC RF system represents a promising non-invasive method of obtaining moderate facial rejuvenation in the appropriately selected patient. Long-term results are pending.

The ethnic nose.

There are distinctive anatomical differences between the non-Caucasian (platyrrhine, mesorrhine) nose and the Caucasian (leptorrhine) nose. In general, non-Caucasian patients requesting aesthetic rhinoplasty desire improvement and refinement of their noses with preservation of defining ethnic characteristics. Surgeons who perform rhinoplasty in this patient population must be familiar with the variations in nasal anatomy and implement augmentation rather than reduction techniques to achieve the desired aesthetic and functional outcomes. We provide a brief review of recent historical trends in ethnic rhinoplasty, highlight relevant anatomical differences, and describe our strategy for addressing the challenges of ethnic rhinoplasty.

Type I thyroplasty for acute unilateral vocal fold paralysis following intrathoracic surgery.

Patients who undergo intrathoracic operative procedures for malignancy may require sacrifice of a recurrent laryngeal nerve. Postoperative vocal fold paralysis may lead to diminished cough with secretion retention, aspiration, and life-endangering pneumonia. This study retrospectively reviews our institution's experience of 23 patients who underwent type I thyroplasty within the 2-week (acute) period after thoracic surgery. Primary lung cancer (n = 16) was the most common disease. Upper lobectomy (n = 9) and pneumonectomy (n = 7) were the most frequent surgical procedures. Silicone medialization alone (n = 11) or with arytenoid adduction (n = 12) was performed. There were no significant postoperative complications. Improvements in hoarseness (86%), dyspnea (72%), dysphagia (50%), and aspiration (79%) were noted. Pulmonary status improved after vocal fold medialization, as reflected by decreased need for therapeutic bronchoscopy in the majority of patients in the postoperative period. Type I thyroplasty for vocal fold paralysis in the acute phase following thoracic surgery is well tolerated and is associated with improved patient outcome with no postoperative deaths in this high-risk patient population.
