Update on brow and forehead lifting.

PURPOSE OF REVIEW: The purpose of this review is to provide the latest findings in the constantly changing field of brow and forehead lifting. Significant articles published in the last 24 months are reviewed and discussed based on the personal experience of the senior author (F.P.). RECENT FINDINGS: Important anatomical findings have been made over the last few years which will have an impact on plastic surgery of the upper third of the face, with new ligamentous structures of the forehead and more precise landmarks of the supraorbital neurovascular bundle being described. The short-term efficacy of a new device for periosteal fixation has been evaluated and new data have been collated about the time required for forehead periosteal readhesion. SUMMARY: In the last few years there have been important anatomical findings which will allow the development of more detailed and safe techniques for forehead lift surgery. New absorbable materials are available that allow efficient mechanical fixation of the soft tissues. The senior author of this review has extensive personal experience involving more than 400 cases. In addition to commenting on recent articles, we detail the methods we have used over the last 8 years, especially regarding the fixation technique.

A 20-year review of the "new domes" technique for refining the drooping nasal tip.

OBJECTIVE: To describe in detail a technique to achieve cephalic rotation, projection, and narrowing of the nasal tip, the "new domes" technique. DESIGN: Retrospective analysis of more than 3000 primary rhinoplasties performed during the last 20 years. SETTING: A private facial plastic surgery practice in Bogotá, Colombia. INTERVENTION: Through an endonasal cartilage delivery approach to the nasal tip, we mold and reorient the alar cartilages with transdomal and interdomal sutures. MAIN OUTCOME MEASURES: Photographic analysis with nasal and facial measurements taken directly from the patient that allows precise diagnosis and preoperative surgical planning. RESULTS: The new domes technique creates a more projected, cephalically rotated, narrowed nasal tip. The results are predictable and stable over time, and patient satisfaction is high because of the natural-appearing results. Complications such as asymmetries, pinching, or retraction of the tip are rare. CONCLUSION: The new domes technique is a conservative, predictable, and stable technique especially applicable for patients with drooped and wide nasal tips to achieve a more projected, rotated, narrowed, and natural appearance.

Seagull wing graft: a technique for the replacement of lower lateral cartilages.

OBJECTIVES: To present and evaluate outcomes with the seagull wing technique, which was designed to replace the lower lateral cartilages and to reconstruct the nasal tip. METHODS: The seagull wing technique is illustrated and described in detail. Sixty patients who underwent surgery 1981 and 2002 were retrospectively evaluated. A preoperative diagnosis of tip deformities was made based on photographs, which were compared with the postoperative results. Patient satisfaction was subjectively evaluated. RESULTS: The postoperative results showed a significant statistical improvement in the following tip deformities: underprojected tip (P<.001), poorly defined tip (P<.001), alar retraction (P<.001), alar pinch (P<.001), overrotated tip (P<.001), and tip ptosis (P<.01). The average follow-up period was 14.6 months. Fifty-five patients (92%) stated that they were very satisfied with the surgical results; they required no additional revision surgery. CONCLUSIONS: The seagull wing technique is a safe and efficient reconstructive treatment for the aesthetic and functional problems that were caused by the overresection of the nasal tip cartilaginous framework. The outcomes were pleasing, and the results were stable during the follow-up period. Patient satisfaction was high.

A review of 25-year experience of nasal septal perforation repair.

OBJECTIVE: To report the long-term follow-up of 25 years of experience in 100 consecutive cases of septal perforation (SP) repair using the technique of the senior author (F.P.). DESIGN: From 1981 to 2006, a total of 100 consecutive patients were surgically treated and followed up for 1 to 10 years. The medical records of 68 of the patients were retrospectively examined. Outcomes were assessed based on comparison of the results of preoperative and last follow-up assessment of SP size and symptoms. The SP repair technique consists of subperichondrial/periosteal dissection, rotation of nasal mucosa for tension-free closure, with no mucosa incision if possible, and a multilayer closure with interposition graft. RESULTS: The most common symptoms were nasal obstruction (72%), crusts (50%), and epistaxis (31%). Previous nasal surgery was the pathogenetic factor in 39 cases (57%). Fifty-two patients (76%) presented with SPs measuring 1.0 to 3.0 cm in diameter. The internal approach was used in 54 cases (79%), and temporal muscle fascia and conchal cartilage were concomitantly used in 45 cases (66%). The great majority of patients (40 [59%]) received more than 5 years of follow-up. The success rate of closure was 97%. Two patients (3%) presented with reperforation measuring less than 1.0 cm in diameter. CONCLUSIONS: The senior author's SP repair technique is easily accomplished, provides good visualization, and is low in cost. Also, in our experience, the success rate of closure has been 97%.
