Reevaluation of the Layered Anatomy of the Forehead: Introducing the Subfrontalis Fascia and the Retrofrontalis Fat Compartments.

BACKGROUND: Novel imaging methods have provided new insights into the layered anatomy of the forehead. This study seeks to critically reevaluate the layered anatomy of the forehead by using ultrasound imaging and cadaveric dissection to provide an accurate anatomical description that can be used to guide safer surgical and minimally invasive frontal procedures. METHODS: This study used ultrasound imaging in a sample of 20 volunteers (12 female and eight male volunteers; aged 35.25 ± 4.2 years; body mass index, 24.28 ± 3.5 kg/m2) and cadaveric dissections of 16 body donors (12 female and four male body donors; aged 72.76 ± 9.5 years) to reevaluate the layered anatomy of the forehead. Layer-by-layer dissections and ultrasound-based measurements of the frontal structures guided conclusions. RESULTS: The following layered arrangement was identified: layer 1, skin; layer 2, superficial fatty layer; layer 3, suprafrontalis fascia; layer 4, orbicularis oculi and frontalis muscle (same plane); layer 5, a homogenous layer of fat [preseptal fat (in the upper eyelid), retro-orbicularis fat (deep to the orbicularis oculi muscle), and retro-frontalis fat (deep to the frontalis muscle); layer 6, subfrontalis fascia; layer 7, preperiosteal fat within the prefrontal space in the lower forehead and deep compartments in the upper forehead; and layer 8, periosteum. CONCLUSIONS: The results of this study add to the current understanding of the layered arrangement of the forehead. The combination of ultrasound imaging and cadaveric dissections provided evidence for a continuous fatty layer deep to the frontalis muscle.

Personal Strategy to Avoid Fat Embolism During Fat Grafting: Brisk Withdrawal of Cannula While Injection.

INTRODUCTION: Complications of fat grafting by means of injection may lead to unwanted passage of substrate into vessel lumens resulting in catastrophic complications. Likewise, a similar trend of complications is observed with non-autologous fillers regardless of an almost generalized use of blunt cannulas, the latter being implicated in the majority of serious vascular complications of hyaluronic acid injection. This report is the product of investigation to review all cases that underwent an original technique of fat injection: "The smart fat injection" during the cannula's brisk withdrawal technique. The aim of this research was to document the safety of this technique by searching if fat embolism had occurred and if yes, its incidence in this group of fat injection surgeries. METHOD: This retrospective review included 3039 patients who underwent the smart fat injection at the facial or corporeal level between 2001 and 2019. The study focused on the search for complications linked to fat yet also cruorical embolism, as the latter may resemble the clinical symptoms of fat embolism. RESULTS: The assessment of the 3039 patients who underwent the smart fat injection during cannula's brisk withdrawal, resulted in none presenting clinically detectable fat or a cruorical embolism. CONCLUSION: This report documents the safety of the smart fat injection developed over a period of 22 years. It further explains the rationale of the technique for avoiding fat embolism while simultaneously enhancing fat take. This technique should not be implemented without appropriate in vitro training.

Partial Removal of the Submaxillary Gland for Aesthetic Indications: A Systematic Review and Critical Analysis of the Evidence.

BACKGROUND: Neck aesthetics is an essential feature for a youthful attractive appearance. Deep neck surgery involving partial resection of the submandibular gland (SMG) has been a controversial issue in aesthetic surgery given its challenging technique and potential risks. The aim of this review is to evaluate the safety and efficacy of partial SMG resection in patients undergoing aesthetic neck surgery. METHODS: We undertook a systematic review of the literature and analysis of studies reporting surgical outcomes and complications of partial SMG resection from Medline, Cochrane and Google Scholar databases from 1950 to March 30, 2019. Two independent reviewers conducted titles and abstracts screening and data extraction. Data were analyzed using mixed methods appraisal tool and a clinical impact score. RESULTS: Six studies including 602 patients who underwent 1200 partial SMG resections were included. All studies reported aesthetic improvement according to Ellenbogen aesthetic neck ideals. Hematoma related to partial SMG resection was encountered in one case (0.08%), hematoma related to cervicofacial skin flap was encountered in 26 cases (1.4%), sialoceles happened in 16 cases (1.3%), transient marginal mandibular nerve weakness occurred in 86 cases (4.7%). No mortalities, permanent motor nerve damage or dry mouth were reported. The clinical impact score was positive for five out of the six reports. CONCLUSION: Partial SMG resection in patients undergoing aesthetic neck surgery may represent an effective procedure to enhance neck aesthetics and is associated with minor, self-limiting complications. Future controlled studies with prospective evaluation of aesthetic outcome and patient-reported outcome measures are needed.

Understanding the Shape of Forehead Lines.

Background: Individualized neuromodulator injections of the forehead are increasingly important to maximize patient safety and satisfaction and to yield the best aesthetic outcome. To assess the location of maximal muscle contraction, it would beneficial to relate the shape and location of the forehead lines to the morphology of the underlying frontalis muscle.

Materials and Methods: We investigated the shape of forehead lines and their relationship to the morphology of the underlying frontalis muscle using anatomic dissection in a sample of 31 human body donors, with a mean age at death of 77.2 ± 13.2 years (range, 47-93) of which n=29 (93.5%) were of Caucasian and n=2 (6.5%) of African-American ethnicity and of which n=16 (51.6%) were females (n=15 males; 48.4%).

Results: Horizontal forehead lines were classified into straight n=13 (41.9%) and wavy n=18 (58.1%) lines. The presence of wavy forehead lines (as compared to straight lines) was significantly related to the presence of a midline aponeurosis (r = 0.69; P less than 0.001) and to a greater muscle fascicle angle (12.67 ± 2.60° vs 10.18 ± 2.12°) (r = 0.47; P less than 0.001), but was not statistical significantly influenced by age, gender, or ethnicity (all P greater than 0.05).

Conclusion: According to the shape of the forehead lines, physicians can appreciate the morphology of the underlying frontalis muscle. This understanding will facilitate more accurate neuromodulator injections and a better aesthetic outcome. It may also result in decreased dosages and increased injection intervals for maximal patient safety. LEVEL OF EVIDENCE: IV

An Update on the Anatomy of the Forehead Compartments.

BACKGROUND: The forehead is one of the most frequent locations for neuromodulator and soft tissue filler applications; however, the underlying anatomy is still poorly understood. Thus far, the presence of deep forehead compartments has not been confirmed. METHODS: Twenty Caucasian cephalic specimens, 15 fresh frozen (six female and nine male) and five with formalin-phenol embalmment (three female and two male) were investigated using contrast-enhanced computed tomographic scans, dye injections, and anatomical dissections. RESULTS: Three superficial (one central and two lateral) and three deep (one central and two lateral) forehead compartments were identified. The superficial fat compartments were found within the subcutaneous fat tissue (layer 2) and measured 2.1 × 4.6 mm for the superficial central forehead compartments and the right superficial lateral forehead compartments and 2.6 × 3.2 cm for the left superficial lateral forehead compartments, with a mean volume of 2.5, 3.1, and 3.4 cc, respectively. The deep fat compartments were identified deep to the frontalis muscle but superficial to the periosteum with an extent of 6.4 × 5.9 cm for the deep central forehead compartments, 2.6 × 5.8 cm for the right deep lateral forehead compartments, and 2.7 × 5.8 cm for the left deep lateral forehead compartments, and a mean volume of 9.1, 1.6, and 1.4 cc, respectively. CONCLUSIONS: The results presented in this study increase the understanding of the forehead anatomy. Understanding the presence of the superficial and the deep forehead compartments allows one to change the signs of frontal aging. The deep forehead compartments are in general avascular planes and permit blunt dissection for access to the supraorbital region.

The Benslimane's Artistic Model for Females' Gaze Beauty: An Original Assessment Tool.

BACKGROUND: The aim of this paper is to analyze the aesthetic characteristics of the human females' gaze using anthropometry and to present an artistic model to represent it: "The Frame Concept." In this model, the eye fissure represents a painting, and the most peripheral shadows around it represent the frame of this painting. The narrower the frame, the more aesthetically pleasing and youthful the gaze appears. MATERIALS AND METHOD: This study included a literature review of the features that make the gaze appear attractive. Photographs of models with attractive gazes were examined, and old photographs of patients were compared to recent photographs. The frame ratio was defined by anthropometric measurements of modern portraits of twenty consecutive Miss World winners. The concept was then validated for age and attractiveness across centuries by analysis of modern female photographs and works of art acknowledged for portraying beautiful young and older women in classical paintings. RESULTS: The frame height inversely correlated with attractiveness in modern female portrait photographs. The eye fissure frame ratio of modern idealized female portraits was similar to that of beautiful female portraits idealized by classical artists. In contrast, the eye fissure frames of classical artists' mothers' portraits were significantly wider than those of beautiful younger women. CONCLUSION: The Frame Concept is a valid artistic tool that provides an understanding of both the aesthetic and aging characteristics of the female periorbital region, enabling the practitioner to plan appropriate aesthetic interventions.

The Benslimane's Artistic Model for Leg Beauty.

BACKGROUND: In 2000, the author started observing legs considered to be attractive. The goal was to have an ideal aesthetic model and compare the disparity between this model and a patient's reality. This could prove helpful during leg sculpturing to get closer to this ideal. Postoperatively, the result could then be compared to the ideal curves of the model legs and any remaining deviations from the ideal curves could be pointed out and eventually corrected in a second session. The lack of anthropometric studies of legs from the knee to the ankle led the author to select and study attractive legs to find out the common denominators of their beauty. METHOD: The study consisted in analyzing the features that make legs look attractive. The legs of models in magazines were scanned and inserted into a PowerPoint program. The legs of live models, Barbie dolls, and athletes were photographed. Artistic drawings by Leonardo da Vinci were reviewed and Greek sculptures studied. Sculptures from the National Archaeological Museum of Athens were photographed and included in the PowerPoint program. RESULTS AND CONCLUSION: This study shows that the first criterion for beautiful legs is the straightness of the leg column. Not a single attractive leg was found to deviate from the vertical, and each was in absolute continuity with the thigh. The second criterion is the similarity of curve distribution and progression from knee to ankle. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Reversing brow lifts.

BACKGROUND: Undesirable brow shape and position may occur after brow lift surgery. Problems can include overelevation of the brows, separation of the brows, and creation of an apex medial slant brow shape. OBJECTIVE: We report on a procedure to restore or improve presurgical brow shape and position. METHODS: Brow lift reversal surgery was performed with open approaches. Anterior and posterior scalp flaps were developed in a subperiosteal plane. The lowered medial brow was sutured to the frontal bone with an anchor system. The repositioned anterior hairline was secured in a similar manner. The scalp defect that results was closed by advancing the posterior scalp flap. Galeal scoring was sometimes necessary to increase the length of the posterior flap. RESULTS: Twenty-two women (average age 45 years; range 32 to 62 years) presented for correction of their brow position and shape after brow lift surgery. All brows were lowered, and the brow apex was shifted laterally. The medial brow was lowered 3 to 10 mm (average, 6 mm) relative to the intercanthal line. The anterior hairline was lowered 5 to 18 mm (average 12 mm). The repositioning has remained stable over 6 months to 3 years' follow-up. No revisionary surgery has been requested. Two patients had areas of alopecia develop in the posterior scalp flap. CONCLUSIONS: The surgically lifted brow can be lowered and reshaped by advancing, repositioning, and fixing the frontal scalp to the skull.
