Medial Oblique Eyelid Split Orbitotomy.

PURPOSE: The authors describe their experience with a variant of the split orbitotomy with a small medial oblique transmarginal incision for approaching a variety of lesions involving the superonasal aspect of the orbit. METHODS: Retrospective review of medical records and clinical photographs of all patients who underwent an unilateral medial oblique incision to access various intraconal lesions abutting the superomedial quadrant of the orbit. The curvature of the medial contour of the operated and contralateral eyelids were expressed with Bézier functions and compared using the R-squared coefficient of determination (R 2 ). RESULTS: Twenty-three patients were submitted to this surgical technique for approaching various unilateral lesions on the superonasal quadrant of the orbit. Excellent cosmesis was achieved in all eyelids, with almost imperceptible scars, and no ptosis or retraction. There was no significant difference between the postoperative medial contour of the operated and the contralateral eyelid, with R 2 ranging from 0.896 to 0.999, mean 0.971. CONCLUSIONS: The authors' results show that the modified eyelid split approach provides a wide exposure of the superonasal quadrant of the orbit with no risk of eyelid dysfunctions or significant scars.

Orbital and paranasal sinuses changes after neonatal orbital exenteration for massive teratoma management.

A neonate at 13 days of age underwent a lid and conjunctiva-sparing orbital exenteration for a massive right orbital teratoma. To reduce the degree of orbital contraction, the entire temporalis muscle was rotated into the orbit along with a dermis-fat graft. Sequential postoperative orbital imaging showed that hyperostosis developed in the orbital apex at the age of two months. Despite a significant expansion of the fat graft, by the age of 4 years, hyperostosis had progressed to the anterior portion of the orbit associated with over-pneumatization of the paranasal sinuses. This case demonstrates that the bony changes in the orbit after neonatal exenteration are complex and involve the development of the paranasal sinuses.

Congenital Opticmeningoceles.

Congenital optic nerve cystic-like malformations associated with normally developed globes are extremely rare. We describe 3 children who presented since birth with proptosis, and eye motility limitation. MRI showed in all cases that the intraorbital segment of the optic nerves was malformed with large cystic-like lesions in the intraconal segment of the orbit. In all cases, biopsies of the wall of the lesions were positive for glial fibrillary acidic protein. Since this protein is a neurobiomarker that exists only in astrocytes in the central nervous system, nonmyelinating Schwann cells of peripheral nerves, and enteric glial cells, we believe that these lesions represent true opticmeningoceles.

Involvement of Multiple Trigeminal Nerve Branches in IgG4-Related Orbital Disease.

PURPOSE: To describe the occurrence of multiple trigeminal nerves (TGNs) enlargement in patients with orbital IgG4-related disease. METHODS: Retrospective review of MRI findings and medical records of 6 patients (10 orbits) with orbital IgG4-related disease and enlargement of more than 1 TGN. Orbital biopsies were performed in all cases revealing the typical lymphoplasmacytic infiltrate with significant plasma cell positivity for IgG4 (IgG4+/IgG ratio ≥ 40%). Three experienced neuroradiologists reviewed the MRI sequences using a digital imaging viewer system (Horos, https://horosproject.org/). RESULTS: Bilateral involvement of at least 2 TGNs divisions was detected in all 6 patients. Enlargement of both V1 and V2 nerves was diagnosed in 5 patients, and in 3 cases, all TGN divisions were involved. V2 nerves were the most affected. In this division, all 12 infraorbital nerves were enlarged, followed by lesser palatines (10/83.3%), superior alveolar (10/83.3%), and zygomatic (6/50%). V1 and V3 nerves were less affected albeit 9 (75%) frontal branches (V1), and 50% of the inferior alveolar (V3) nerves were also enlarged. CONCLUSIONS: Widespread involvement of the TGN is an important feature of IgG4-related disease.

Frontalis Linkage Without Intraoperative Eyelid Elevation for the Management of Myopathic Ptosis.

PURPOSE: To report the effect of frontalis linkage without intraoperative eyelid elevation for the management of myopathic ptosis. METHODS: Retrospective analysis of 21 (42 eyelids) myopathic patients with bilateral ptosis who were operated between 1999 and 2017. All patients had orbicularis weakness and poor or absent Bell's phenomenon. Surgery consisted of using an autogenous fascia sling to link the tarsal plate to the frontalis muscle without any degree of intraoperative eyelid elevation. The main outcome measures were margin reflex distance, brow height and degree of brow excursion and degree of lagophthalmos, and exposure keratitis. RESULTS: After surgery, there were significant changes (p <0.0001) in both margin reflex distance and brow position. Mean margin reflex distance increased to 1.4 mm ± 1.34 DP and with full frontalis contraction, it reached 3.0 mm ± 1.73 DP, while mean brow position decreased 1.6 mm ± 1.59 SD, p < 0.0001. Postoperative lagophthalmos was not detected in 31 (74%) eyes. In the remaining 11 eyes (26%), lagophthalmos ranged from 1.2 to 5.2 mm (mean = 1.7 mm ± 0.74 DP). Mild inferior superficial keratitis was detected in 14 eyes (33.3%) of 7 patients only 3 of which had lagophthalmos. One patient needed additional surgery to correct unilateral eyelid retraction. Overall, 81.81% of the patients were pleased with the procedure. CONCLUSIONS: Myopathic ptosis can be alleviated with a minimal amount of lagophthalmos by just linking the tarsal plate to the frontalis muscle without lifting the eyelid margin intraoperatively.

Long-Term Results of the Surgical Management of the Upper Eyelids in "Ablepharon"-Macrostomia Syndrome.

PURPOSE: To describe the late results of the placement of skin graft over conjunctiva-Müller muscle complex in 3 patients with ablepharon-macrostomia syndrome (AMS) and to review the procedures used to manage the upper eyelids in AMS. METHODS: The authors searched the Pubmed database for all articles that used the term "ablepharon-macrostomia syndrome" in any field. Data collection included description of eyelid changes, age at surgery, status of the cornea before surgery, type of eyelid repair, and final outcome. Two previously reported siblings were reevaluated 10 and 15 years after a single reconstructive operation. A new case from Peru is also described. RESULTS: Only 15 patients with AMS have been described in 12 articles. In 60% of the cases, the lids were described as absent. The surgical modalities employed to reconstruct the upper eyelids were quite variable, including local flaps, lid sharing procedures, and even a masquerade flap. At long-term follow-up, all 3 cases who underwent upper eyelid lengthening with full thickness skin grafts placed over Müller muscle had clear corneas with a small amount of lagophthalmos. CONCLUSIONS: The lids in AMS are not absent and should not be managed with complex reconstructive techniques. Full thickness skin grafts placed over the inner aspect of the palpebral conjunctiva allow permanent eye protection.The upper eyelids in ablepharon-macrostomia syndrome can be permanently lengthened with full thickness skin grafts over Müller muscle.

Orbital Bone Decompression for Non-Thyroid Eye Disease Proptosis.

PURPOSE: To report a multicenter large case series of orbital decompression for non-thyroid eye disease proptosis. METHODS: Retrospective chart review of cases of orbital decompression performed by 9 experienced orbital surgeons from different countries from 2014 to 2017 for non-thyroid eye disease proptosis. Patients were divided into 3 groups: 1) negative vector (high axial length or shallow orbit), 2) inflammatory, and 3) tumor. Types of orbital decompression and Hertel exophthalmometry (preoperative and minimum 6 months postoperative) were recorded. Charts were also assessed for serious complications. The amount of exophthalmometry improvement was recorded according to the above groups. RESULTS: The analysis included 41 orbits of 29 patients (14 women and 15 men) with a mean age of 38.9 years (ranging from 9 to 74; standard deviation (SD) 15.66). There were 17 orbits of 11 patients in the negative vector group, 16 orbits of 10 patients in the inflammatory group, and 8 orbits of 8 patients in the tumor group. The mean reduction of proptosis was 2.95 mm in the negative vector group, 2.54 mm in the inflammatory group, and 5.75 mm in the tumor group. There were no serious complications. CONCLUSIONS: Orbital decompression was safe and effective in reducing proptosis for non-thyroid eye disease indications in this series. The amount of exophthalmometry improvement was less in the inflammatory orbitopathy group compared with other proptosis etiology groups.Orbital decompression may have a role in improving proptosis in non-thyroid eye disease entities.

Woakes Syndrome: A Rare Cause of Proptosis due to Sinonasal Polyposis.

The authors report 2 consecutive adult male patients, aged 61 and 38 years, who presented with painless unilateral proptosis. Their past medical histories were negative for asthma, allergies, and Graves disease. On examination, the nose bridge of the eldest patient was clearly enlarged. Computed tomography scans of the orbits and paranasal sinuses showed in both patients the same radiologic pattern of hyperdense ethmoidal opacifications and expansion of the inferomedial orbital floor. Histopathological analysis of the ethmoidal cells mucosa obtained during inferomedial decompression revealed benign sinonasal polyposis. These cases demonstrate that asymptomatic sinonasal polyposis can be a rare cause of proptosis.

Characteristics and management of congenital anophthalmos and microphthalmos at a tertiary eye hospital.

Purpose: The purpose of the study is to evaluate demographic data and outcomes of the management of congenital anophthalmia/microphthalmia. Methods: This retrospective, descriptive, cross-sectional study evaluated patients with congenital anophthalmia/microphthalmia managed from 2004 to 2014 at a tertiary hospital in Saudi Arabia. Data were collected on patient age, gender, cause, orbital status, laterality, systemic comorbidities, ocular evaluation, and management (type of surgery, type of orbital implant, and complications). The main outcome measure was the ability to hold the prosthesis. Results: The study sample was composed of 513 eyes/sockets of 365 patients. Two-hundred and seventeen (59.4%) patients were unilateral cases. Forty-one (8%) sockets were due to congenital anophthalmia and 471 (92%) were due to microphthalmia. There were 73.2% isolated cases and 28.5% with systemic involvement. Systemic involvement was more common in bilateral cases. The most commonly associated conditions were central nervous disorders. One-hundred and nineteen (46.7%) cases had parental consanguinity. Two hundred and eighteen eyes/sockets (163 patients) underwent surgery including conjunctival flap (38; 17.4%), evisceration (38; 17.4%), enucleation (16; 7.3%), or procedures to improve the anophthalmic socket volume (45; 20.6%). Volume enhancing procedures included polymethylmethacrylate orbital implants (26; 57.8%), expanders (11; 24.4%), integrated hydroxyapatite or polyethylene implants (2; 4.4%), and dermis-fat graft (6; 13.3%). In most cases, clinical or surgical management resulted in a successful outcome. Conclusion: Anophthalmia/Microphthalmia was detected in 36.5 patients/year. The majority had isolated microphthalmia. Good outcomes were achieved with clinical or surgical management in the majority of cases.

Symmetry of Upper Eyelid Contour After Unilateral Blepharoptosis Repair With a Single-strip Frontalis Suspension Technique.

PURPOSE: To analyze the upper eyelid contour of patients with unilateral congenital ptosis who underwent single-strip frontalis suspension. METHODS: The authors compared the upper eyelid shape of the right and left eyes of 10 patients who underwent unilateral frontalis suspension with a single strip of autogenous fascia. At a mean postoperative time of 10.1 ± 4.01 months, the image J software was used to measure the ratio between the nasal and temporal areas of the upper half of the palpebral fissure. The midpupil upper eyelid distance (MRD1) was also measured on the photos with the same software. The nonparametric Wilcoxon signed-rank test was used to compare the data. RESULTS: Postoperative MRD1 ranged from 2.5 to 4.7 mm (median = 3.8) on the affected side. The MRD1 for nonoperated eyelid ranged from 1.8 to 5.0 mm (median = 3.5). On the operated side, the temporal areas ranged from 50.3 to 85.7 mm (median 65.2) and nasal areas ranged from 41.5 to 72.3 (the median was 60.1). In the contralateral, nonoperated palpebral fissures, the temporal areas ranged from 42.7 to 94.3 mm (median = 54.5) and the nasal areas ranged from 36.8 to 86.1 mm (median 52.3). The T/N ratio distributions were almost identical between groups, ranging from 0.9 to 1.2 (median = 1.1) in the operated eyes and from 0.9 to 1.3 (median = 1.1) in the fellow eyes. CONCLUSIONS: In autogenous fascia frontalis suspension procedures, the upper eyelid contour of the ptotic eyelids can be adequately normalized with a single area of traction on the tarsal plate.

Interlamellar Autogenous Tarsal Graft for the Correction of Lower Eyelid Trichiasis Associated With Eyelid Margin Thinning.

PURPOSE: To evaluate the use of autogenous tarsal graft for surgical correction of lower eyelid trichiasis associated with eyelid thinning. METHODS: A total of 23 eyelids of 19 consecutive patients with trichiasis were operated with a variant of the Van Millingen procedure. The surgery consisted of interposing a 3-mm high fragment of autogenous ipsilateral upper eyelid tarsus corresponding to the trichiasis segment between the pretarsal anterior lamella and the lower tarsal plate. Preoperative assessment included quantification of eyelid thickness on the midpoint of the segment with trichiasis, biomicroscopy of the eyelid margin and location of the trichiasis. All patients were examined at 1, 3, 6, and 12 months after surgery. Eyelid thickness was measured at 1 month and 12 months of follow up. RESULTS: Preoperatively the mean thickness of the eyelid margin was 0.99 mm ± 0.06 standard error. One month postoperatively eyelid thickness increased to 2.08 ± 0.28 standard error, decreasing over time to reach 1. 48 mm ± 0.18 standard error 1 year after surgery, a value that did not differ from that of the control group. Small granulomas were diagnosed only in the early phases of the postoperative period. Trichiasis recurrence was seen in just 1 eyelid. Isolated abnormal lashes lateral or medial to the graft were present in 5 eyelids at the end of the study. CONCLUSIONS: Autogenous tarsal grafts placed parallel to the lower tarsus are a good option both to correct misdirected eyelashes and to restore normal lower eyelid thickness.

Lacrimal Gland Involvement in Blepharophimosis-Ptosis-Epicanthus Inversus Syndrome.

PURPOSE: To describe the involvement of the lacrimal gland (LG) in blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). DESIGN: Observational, cross-sectional study. PARTICIPANTS: Twenty-one patients with BPES (10 female, 11 male) aged on average 15 years (range, 2-39 years), from 3 Brazilian medical centers and 1 Portuguese medical center. METHODS: Patients had their ocular surface evaluated with slit-lamp biomicroscopy, and tear production quantified with the Schirmer test I. The LG volumes were measured on computed tomography (CT) scans in the BPES sample and in a group of age-matched subjects imaged for nonorbital diseases. Sixteen patients were screened for mutations in the FOXL2 gene. MAIN OUTCOME MEASURES: Lacrimal meniscus height, Schirmer test I, presence of superficial punctate keratopathy (SPK), LG volume, and molecular analysis of the FOXL2 gene. RESULTS: Absence of LG was detected bilaterally in 9 patients (42.8%) and unilaterally in 2 patients (9.5%). When considering only patients with measurable LG, the median volume was 0.22 cm3 in the right eye (range, 0.06-0.36 cm3) and 0.24 cm3 in the left eye (range, 0.08-0.34 cm3). These values were significantly lower than those for the age-matched controls (median = 0.54 right eye and 0.53 left eye; P < 0.05). There was a significant association between deficiency of tear production and LG volume reduction and agenesis. Molecular analysis of the FOXL2 gene revealed the presence of 8 distinct mutations, 4 of them novel ones. A significant reduction of LG size or agenesis was associated with mutations affecting protein size (due to underlying changes in the stop codon location) or the DNA-binding forkhead domain (Fisher exact test, P = 0.021). In 3 probands, the underlying genetic defect was not found. CONCLUSIONS: This is the first study reporting LG volumes in BPES, describing a significant number of patients with LG agenesis. The association between alacrima and BPES is not incidental, and a thorough evaluation of tear production is recommended especially if ptosis surgery is planned.

Hyperostosis Following Orbital Exenteration.

PURPOSE: To describe CT scan findings following orbital exenteration in 27 patients and to identify the factors involved in the development of post exenteration hyperostosis. METHODS: Noncomparative case series. The authors reviewed the charts of 27 patients ranging in age from 33 to 99 years, who underwent unilateral exenteration at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia and at the School of Medicine of Ribeirão Preto, University of São Paulo, Brazil. Data regarding patient demographics, surgical procedure, clinical diagnosis, and preoperative and postoperative CT imaging of the orbits were obtained. The relationship between hyperostosis and postoperative time, gender, age, adjuvant radiotherapy, and cavity coverage was evaluated by multivariate stepwise logistic regression. RESULTS: Seventeen (73.9 %) orbits had postoperative orbital hyperostosis. No soft tissue masses were detected in the affected orbits except in 2 cases with tumor recurrence. The only factor associated with hyperostosis was immediate intraoperative socket rehabilitation (odds ratio = 0.13, 95% confidence interval: 0.01-0.89). There was an 87.0% lower chance of hyperostosis in patients whose socket was covered with musculocutaneous flaps. Sequential CT scans showed that orbital hyperostosis followed a specific pattern. Initially, bone thickening appeared as either uniform or undulating endo-osteal minimal thickening along the roof and then on the lateral and medial walls. More advanced hyperostosis had a laminated/lamellated appearance progressing to homogeneous and diffuse circumferential bone thickening. New bone formation and bone overgrowth were late findings. Hyperostosis extended to involve the adjacent facial bone, more obviously on the maxilla. Some patients had minimal thickening of the adjacent frontal and squamous temporal bone. Over-pneumatization of the paranasal sinuses was evident in all cases of hyperostosis. CONCLUSIONS: Development of hyperostosis following exenteration is not rare. Radiologists and surgeons should be aware of the need to monitor the orbital healing process closely to avoid misdiagnoses of tumor recurrence/radionecrosis or infection. Obliteration of the orbital cavity with musculocutaneous flaps significantly reduces the chances of bone hyperostosis.

Dacryocystocele After Successful External Dacryocystorhinostomy: A Variant of the Lacrimal Sump Syndrome.

A 25-year-old man presented with a mass on the right medial canthus after a successful dacryo cys torhinostomy performed 3 years ago. On examination, there was a firm, nondepressible mass inferior to the medial canthal ligament and a linear vertical scar on the lateral wall of the nose. Syringing through the right lower punctum indicated his lacrimal system was patent. Computed tomography and magnetic resonance imaging disclosed a large cystic lesion in the lacrimal sac fossa. No bone erosion was detected. The mass was approached through a tear trough incision and completely resected. The lacrimal anastomosis that was highly placed remained patent after surgery. Histopathology of the specimen revealed a cystic lesion compatible with lacrimal origin (dacryocystocele).

Complications and Management of Polymethylmethacrylate (PMMA) Injections to the Midface.

BACKGROUND: Polymethylmethacrylate (PMMA) has been used as an injectable filler to treat hollows and reduce rhytids. PMMA injections have been associated with several side effects, however, the literature is scarce on periorbital complications and their treatments. OBJECTIVES: The purpose of this study is to report a series of complications after periorbital PMMA injections to the midface and to describe their management. METHODS: Retrospective chart review, including photography and histopathology when available. RESULTS: The authors identified 11 cases of complications of PMMA injections to the midface. Patient ages ranged from 36 to 62 years (mean, 47 years; median, 44 years). Two (18%) were males and 9 (82%) were females. Adverse effects began between 2 to 24 months after injection (mean, 7.2 months; median, 6 months). All patients had edema, erythema, and contour irregularity. Seven (64%) patients had nodules, 4 (36%) had yellow, xanthomatous skin changes, and 2 (18%) had eyelid malposition. Histopathology demonstrated a giant cell inflammation in 5 of 6 cases. Corticosteroid injection was tried in 6 cases but was associated with minimal clinical improvement. Surgical debulking of the implanted material was performed in 9 (82%) cases and was effective in improving edema, erythema, and nodularity. CONCLUSIONS: PMMA injection to the midface may be associated with chronic inflammation, fibrotic nodules, yellowing of the skin, and eyelid malposition. Intralesional corticosteroid injections yielded minimal or no improvement; surgical debulking achieved favorable results. LEVEL OF EVIDENCE 4: Therapeutic.

Globe Protrusion and Interorbital Divergence in Syndromic Faciocraniosynostoses.

PURPOSE: The aim of this study was to quantify the relationship between globe protrusion (GP), length of medial and lateral walls, interzygomatic distance, and interorbital angle in syndromic faciocraniosynostoses. METHODS: The axial slices of computed tomography of the orbits of 43 patients with faciocraniosynostosis (31 with Crouzon syndrome and 12 with Apert syndrome) and 23 control subjects were measured with the Image J software. The following 5 variables were quantified: the degree of GP, the length of the medial and lateral walls, the interzygomatic distance, and the interorbital angle. RESULTS: Independent t-tests revealed significant differences between the patients and the controls regarding the mean values of all variables measured. The degree of GP was better correlated with the interorbital angle (r = 0.81) than with the medial wall length (r = 0.73). No correlation was found between GP and lateral orbital wall length. CONCLUSIONS: In syndromic faciocraniosynostoses, GP is highly correlated with the interorbital angle. The increment in the interorbital angle is a natural geometric consequence of the fact that a decrease in the orbital depth is not adequately compensated by an increase in the distance between the lateral orbit rims.

Supramaximal levator resection for unilateral congenital ptosis: cosmetic and functional results.

PURPOSE: To analyze the cosmetic and functional results of a large series of patients with unilateral congenital ptosis without spontaneous compensatory ipsilateral frontalis hyperaction who underwent supramaximal levator resection (SMLPSr). METHODS: A multicenter retrospective review of 35 children (14 girls and 21 boys) of mean age 5.5±3.6 SD years with unilateral congenital ptosis who underwent surgery in 3 different countries: Italy, n=8; Argentina, n=11; and Brazil, n=16. Preoperative evaluation included measurements of upper eyelid margin reflex distance (MRD1) and levator palpebrae superioris muscle excursion, assessment of frontalis hyperaction, and ocular motility examination. At least 6 months postoperatively, photographs were used to measure the upper eyelid contour of OU. The spontaneous blinking amplitude and downward eyelid saccades of OU were quantified in a subset of 14 patients. Quantitative comparison among the 3 centers was performed with nonparametric 1-way analysis of variance (Kruskal-Wallis). Paired t tests were used to compare the pre- and postoperative measurements, and p value<0.05 was statistically significant. RESULTS: The mean preoperative MRD1 of the operated eyes increased from 0.5±1.1 SD mm to 3.4±0.84 SD mm (t=15.9; p<0.000001), consequently the eyelid positional asymmetry decreased from 3.1±1.21 mm to 0.1±0.86 SD mm (t=16.5; p≤0.000001). Twenty-nine percent of eyelids had mild contour abnormalities and 31.4% showed some degree of lash ptosis. Spontaneous blinks were abnormal in 93% of the cases (eyelids). The amplitude of the abnormal blinks ranged from 12.9% to 65.4% (mean=37.1%) of the contralateral eyelids. Downward eyelid saccades were reduced in 79% of the eyelids. The amplitudes the saccades ranged from 2.2% to 84.6% (mean=54.8%). CONCLUSIONS: In unilateral congenital ptosis, SMLPSr effectively reduces the positional asymmetry between eyelids. Mild contour abnormalities and lash ptosis are the main complications of the surgery. Postoperatively, spontaneous blinks and downward saccades were reduced in most eyelids. The reduced postoperative eyelid kinetics indicates that only patients with normal upward Bell signs are good candidates for this procedure.

Fox eyes lift-A new protocol for eyebrow elevation with laser Fotona.

BACKGROUND: The eyelids play an important role in our appearance and are usually the first to show signs of age. The Fotona SP Spectro Systems consist of a range of noninvasive laser treatments that work together synergistically to tighten the collagen in four dimensions and provide long-lasting firmness to the face. The Fotona SP Spectro combines two wavelengths: Er:YAG (2940 nm) and Nd:YAG (1064 nm) with four distinct treatments: SmoothLiftingTM, FRAC3®, PIANO®, and SupErficialTM, allowing safe, painless, noninvasive, and no downtime rejuvenation. AIMS: To present a new protocol of treatment with Fotona SP Spectro for eyebrow elevation, which we call fox eyes lift (FEL), and compare it to the standard SmoothEye® (SE) protocol. METHODS: This is a prospective, interventional, split-face study. The sample consisted of 21 subjects (19 women) with a mean age of 50.1 ± 7.9 years who underwent two different protocols, that is, SE on one side and FEL on the other. The protocol used on each side was selected by drawing lots. Three sessions were held at 1-month intervals. Standardized photographic documentation was obtained before and 30 days after the end of treatment. Eyebrow position before and after complete treatment was quantified using ImageJ software. RESULTS: Statistical analysis by ANOVA showed a significant improvement in eyebrow position after treatment with both protocols, with a significantly greater effect of FEL (p = 0.0003 d = 0.95). CONCLUSION: Fox eyes lift is an efficient and safe technique providing significant improvement in the position of the eyebrow.
