ABSTRACT

Background Among the cleft types, bilateral cleft lip and palate (BCLP) generally requires multiple surgical procedures and extended speech therapy to achieve normal speech development. This study aimed to describe speech outcomes in 5-year-old Korean children with BCLP and examine whether normal speech could be achieved before starting school. Methods The retrospective study analyzed 52 children with complete BCLP who underwent primary palatal surgery at a tertiary medical center. Three speech-language pathologists made perceptual judgments on recordings from a speech follow-up assessment of 5-year-old children. They assessed the children's speech in terms of articulation, speech intelligibility, resonance, and voice using the Cleft Audit Protocol for Speech-Augmented-Korean Modification. Results The results indicated that at the age of five, 65 to 70% of children with BCLP presented articulation and resonance within normal or acceptable ranges. Further, seven children with BCLP (13.5%) needed both additional speech therapy and palatal surgery for persistent velopharyngeal insufficiency and speech problems even at the age of five. Conclusion This study confirmed that routine follow-up speech assessments are essential as a substantial number of children with BCLP require secondary surgical procedures and extended speech therapy to achieve normal speech development.

ABSTRACT

Philtrum reconstruction in patients with unilateral cleft lip is a major concern in cheiloplasty. Moreover, a quantitative evaluation of the philtrum contour has not been possible. Advances in 3-dimensional (3D) imaging technology have enabled highly accurate assessments of facial surfaces. This study aimed to justify using 3D anthropometric measurements to quantify traditional photographic grading systems. Sixty-six children with unilateral cleft lip, aged 4 to 6 years (mean age: 69.1±5.7 mo), who visited the outpatient clinic from January to December 2020 were included. A plastic surgeon panel graded the philtrum contour using digital photographs, and 3D anthropometry was performed using a 3D imaging system. The philtrum height, philtrum height difference, and dimple depth were measured at the middle of the philtrum. The philtrum height did not show significant changes across the photographic scores ( P =0.06), whereas noticeable differences were observed in the dimple depths based on photographic scores ( P <0.001). The correlation analysis revealed the highest correlation between the photographic score and dimple depth (rho=0.897, P <0.001). The philtrum height on the cleft side (rho=0.478, P <0.001) also correlated with the photographic score, but the correlation was weaker than that of the dimple depth. The dimple depth and philtrum height can help define the philtrum contour. Furthermore, the dimple depth reflects the philtrum contour better and is more suitable as a single parameter. However, relying on a single philtrum height measurement may be insufficient for reliable evaluations, as the relative height from the surrounding tissues is more important than the absolute height measured using 3D anthropometry.

ABSTRACT

BACKGROUND: We investigated postoperative nasal morphology changes in patients undergoing secondary correction of cleft lip nose with septal repositioning and alar cartilage suspension during preschool age. METHODS: We performed a retrospective review on 77 patients who underwent secondary correction of cleft lip nose. The patients were aged 5‒6 years and underwent intermediate rhinoplasty by alar cartilage suspension, with or without septal repositioning. They were divided into two groups based on time: septal repositioning (Sep. 2015-Nov.2017) and control (Nov. 2009-Aug. 2015) groups. We performed a photogrammetric comparison by assessing the postoperative nasal morphology changes using linear and angular parameters. The cleft-to-non-cleft side ratio of each parameter was measured for the nostril width and height, nostril area, and caudal septal deviation angle. RESULTS: Among the 77 patients, 43 were selected as the septal repositioning group and 34 as the control. The evaluation timing was 5.32 ± 0.45-year-old for the preoperative period (T0), 6.57 ± 0.5-year-old for short-term (T1), and 9.28 ± 0.65-year-old for long-term follow-up (T2). The septal repositioning group showed significantly improved nostril width ratio and caudal septal deviation angle in the T1 and T2 periods. The septal repositioning significantly decreased the nostril area ratio in the T1 and T2 periods due to decreased cleft side and increased non-cleft side nostril area. CONCLUSIONS: The secondary correction of cleft lip nose with septal repositioning during preschool age offers a second chance to correct nasal appearance by balancing the nostril symmetry and correcting the caudal septal deviation.

ABSTRACT

BACKGROUND: In unilateral cleft nasal deformity, the skeletal, and cartilaginous framework of nose is deformed. The anterior nasal spine (ANS) is usually displaced to the non-cleft-side. In cleft orthognathic surgery, ANS relocation can help correct the deviated ANS and nasal septum and might lead to an improved esthetic and functional outcome. METHODS: Patients with unilateral cleft lip who underwent two-jaw orthognathic surgery between July 2016 and July 2020 were reviewed retrospectively. During conventional two-jaw orthognathic surgery, the ANS was separated from the maxilla. The separated ANS with the attached septum was fixed on the maxillary midline by wiring. Computed tomography scan was used to measure the septal deviation angle and septal deviation from the midline. RESULTS: The septal deviation from the maxillary midline decreased following surgery (preoperative versus postoperative: 4.6 ±â€Š1.0 mm versus 3.2 ±â€Š1.2 mm; P = 0.016). The coronal septal deviation angle was widened after ANS relocation, although the transverse septal deviation angle remained unchanged (coronal septal deviation angle, preoperative versus postoperative: 146.7 ±â€Š12.6 versus 159.8 ±â€Š7.6; P = 0.01; transverse septal deviation angle, preoperative versus postoperative: 156.5 ±â€Š11.7 versus 162.8 ±â€Š7.7; P = 0.128). CONCLUSIONS: This study suggests that simultaneous ANS relocation with orthognathic surgery is a viable option for cleft-related deformities, considering the resultant caudal septum straightening and stable structural support observed in the long-term.

ABSTRACT

BACKGROUND: Worm's eye view photograph has been widely used for anthropometric analysis. However, it is difficult to secure objectivity because it cannot be captured at a constant head-up degree. This study aimed to analyze whether anthropometric nasal measurements in worm's eye view differ from the actual values. METHODS: A total of 40 patients with unilateral cleft lip nasal deformities were included. The 30° and 60° head-tilted two-dimensional (2D) photographs were captured from the three-dimensional (3D) images. The real measurements were obtained from 3D images and 2D measurements were obtained from the captured images. The cleft/non-cleft side ratios of the nostril height, width, and alar base width were compared between 3D and 2D images. RESULTS: There was a significant difference in the nostril height between the 3D and 30° values (3D = 0.82, 30°â€Š= 0.92, P < 0.001) but no meaningful difference was noted between the 3D and 60° values (3D = 0.82, 60°â€Š= 0.84, P = 0.31). There was no significant difference in the nostril width among the 30°, 60°, and 3D values. A significant difference was found in the alar base width between the 3D values and both the 30° (3D = 0.998, 30°â€Š= 1.04, P = 0.026) and 60° (3D = 0.998, 30°â€Š= 1.03, P = 0.029) values. CONCLUSIONS: This study demonstrates that 2D photographs do not accurately reflect actual values. The nostril height and alar width ratio can be changed depending on the head-up position. The 3D systems are more accurate and less affected by the subject's head position. Therefore, the 3D imaging system is advocated for the anthropometric analysis of unilateral cleft lip nasal deformity.

ABSTRACT

BACKGROUND: This study aimed to identify the initial diagnostic characteristics and treatment status of children with submucous cleft palate (SMCP) and to examine the relationship between the timing of surgical correction and the degree of articulation and resonance improvement. METHODS: This retrospective study included 72 children diagnosed with SMCP between 2008 and 2016. The evaluation criteria were the age of the initial visit, total number of visits, age at the end of treatment, speech problems, resonance problems, and speech therapy. RESULTS: Children with SMCP first visited the hospital at an average age of 34.32 months, and speech problems were identified at an average age of 48.53 months. Out of 72 children, 46 underwent surgery at an average age of 49.74 months. Four of these children required secondary surgery at an average age of 83.5 months. Among the children who underwent surgery before 3 years of age, 70% exhibited articulation improvements, with mild-to-moderate hypernasality. Articulation improvements showed no statistically significant differences according to age at the time of surgery. However, children who underwent surgery before 4 years had a better hypernasality rating than those who underwent surgery after 4 years of age. CONCLUSIONS: Children with SMCP tend to undergo delayed treatment because the anatomical symptoms in some children with SMCP are unclear, and surgical interventions are considered only after speech problems are clarified. Starting interventions as early as possible reduces the likelihood of receiving secondary surgery and speech therapy, while increasing expectations for positive speech function at the end.

ABSTRACT

The focus of secondary rhinoplasty for patients with a cleft lip after facial growth has been on correcting nasal tip asymmetry and distorted cleft-side lower lateral cartilage. However, some patients present with mid-vault asymmetry even after secondary rhinoplasty. The authors propose camouflage procedures for patients with a unilateral cleft lip and without symptoms of nasal airway obstruction. In camouflage procedures, autologous cartilage or acellular dermal matrix was used for onlay grafting and placed on the upper lateral cartilage. In this report, case examples are described to illustrate the surgical techniques and results. This method enables the correction of mid-vault asymmetry without the use of an additional septal spreader graft.

ABSTRACT

BACKGROUND: Reconstruction in tongue cancer to restore the shape and function of the tongue without airway obstruction in the narrow oral cavity is challenging for reconstructive surgeons. Herein, the authors retrospectively analyzed flaps to reveal the factors that affect the functional outcome of tongue reconstruction. METHODS: Herein, we retrospectively reviewed 30 patients (men, 16; women, 14; mean age, 50.3 years) who underwent the hemi-tongue reconstruction followed by speech therapy between 2009 and 2017. Data about postoperative chemotherapy and radiotherapy were collected. The dimensions (width and length) of the flaps were measured. Speech outcomes were assessed under the conditions of varying distances of the tongue tip from lower incisors when it was protruded, retracted, and elevated. Lateralization was evaluated based on the count of teeth reached by the tip of the tongue from the midline. RESULTS: Preoperative chemotherapy and radiotherapy significantly influenced tongue retraction, tongue articulation, and intelligibility (p = 0.006, 0.002, 0.048, respectively). Postoperative chemotherapy did not statistically significantly influence any outcome measure. Contralateralization of the tongue was significantly decreased in the postoperative radiotherapy group (p = 0.029). The length of the flap showed highly negative correlation with articulation and intelligibility (p = 0.009, p< 0.001, respectively). The width of the flap was not correlated with the outcomes. CONCLUSION: We proved that unlike chemotherapy, postoperative radiotherapy influences the functional outcome of tongue reconstruction. The dimensions, particularly the length of the flap, were also important for restoring the reconstructed tongue function.

ABSTRACT

BACKGROUND: A practical application of three-dimensional printing technology has been considered a difficult area in rhinoplasty. However, the patient-specific three-dimensionally printed rhinoplasty guide based on the simulation program the authors developed could be a solution for minimizing the gap between simulation and actual surgical results. The aims of this study were to determine how a three-dimensional rhinoplasty guide based on three-dimensional simulation would link the patient to the surgeon to investigate its effectiveness. METHODS: Fifty patients who underwent rhinoplasty between January of 2017 and February of 2018 were included in this study. The patients were consulted about the desired shape of their nose based on preoperative three-dimensional photography. The confirmed three-dimensional simulation was sent to a manufacturing company for three-dimensionally printed rhinoplasty guides. In the guide group, rhinoplasty was performed based on the three-dimensionally printed rhinoplasty guide, and in the control group, procedures were performed based on the surgeon's intuition. RESULTS: The intraclass correlation coefficient test for comparing the simulated and postoperative measurements showed higher correlation in the three-dimensional printing guide group: higher correlation 11.3 percent in nasal tip projection, 21.6 percent in dorsum height, and 9.8 percent in nasolabial angle. The postoperative result of the nasal dorsum had a statistically significant difference between the two groups (p < 0.05). CONCLUSIONS: This study demonstrated the usefulness of the three-dimensionally-printed rhinoplasty guide, which delivers the preoperative simulated image in the actual clinical practice of rhinoplasty. This approach could cause a paradigm shift in simulation-based rhinoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

ABSTRACT

The characteristics of what is considered a beautiful face differ between Eastern and Western countries.The authors of this study analyzed beauty pageant contestants using a three-dimensional (3D) photogrammetric analysis tool. All of the 3D photographs were taken between October and November 2016 in Seoul, Korea. The participants were 43 Miss Korea contestants (Group I) and 22 Miss Paraguay contestants (Group II).In absolute length, those in Group I had longer upper and middle faces. In the proportions of volume and length, Group I had larger upper and middle faces than Group II. Widths of the lower face and entire face were also wider in Group I. The lower facial index was larger in Group I. Group I had longer noses and wider intercanthal distance, not only in absolute length but also in proportion to the face. Group II showed thicker lips, longer chins, and wider noses relative to the face. Group II had wide eyes, in the absolute measurement and in proportion to the face. Group I participants appeared to have an increased height of eyes and had wider angles in their faces as well as wider nasofrontal, labiomental, and nasomental angles.The authors objectively established reference data for faces that are considered attractive in the East and the West. The data are expected to contribute to the clinical practice of plastic surgeons.

ABSTRACT

BACKGROUND: This study was conducted to evaluate the impact of choosing a particular recipient venous system on venous patency and flap survival in 652 head and neck free flap reconstructions. METHODS: A retrospective review was performed. Patient factors investigated included: age, sex, type of flap, tumor location, history of radiation, presence of previous neck dissection, tumor stage, and any underlying disease. Data related with recipient vein including the number of anastomosis, the repair technique, the type of recipient vein, and the configuration of selected venous system were examined. The impact of patient factors and parameters related with recipient vein on the venous patency and flap survival were analyzed using bivariate and multivariate analyses. RESULTS: Of 652 free flaps, 36 flaps (5.5%) were re-explored due to venous congestion and 28 flaps (77.8%) were salvaged. The overall survival rate of total free flaps was 98.8%. The type of recipient venous system was found to be an insignificant factor with respect to venous congestion and flap survival in multivariate analysis. A history of radiation treatments was the only factor associated with a higher risk of venous compromise (odds ratio [OR] = 13.138, p < 0.001) and a lower rate of flap survival (OR = 20.182, p = 0.002). CONCLUSION: The selection of recipient venous systems has no impact on venous patency and flap survival. History of radiation treatment was the only factor associated with venous congestion and flap failure. Since no single method can ensure a successful reconstructive result, selecting the optimal recipient vein should be based on individual patient factors and the surgeon's experience.

ABSTRACT

PURPOSE: Intermaxillary fixation (IMF) using the arch bar has been the standard technique for a long time in the management of mandibular fracture. But because of several complications, intermaxillary fixation with screws has been introduced and adopted to use. This investigation compared the outcomes and complications between the traditional IMF and modified intermaxillary fixation with screws techniques in terms of the malocclusion, surgical time, root injury, and screw or arch bar failure. METHODS: This retrospective review included 66 patients who underwent reconstruction of mandibular fractures that uses traditional arch bar or IMF screws as IMF. Preoperative and postoperative facial bone computed tomography, panoramic x-ray were used to evaluate the patients. The complaints and complications were recorded in electric medical record based on patients' consultation during follow-up. RESULTS: The total complication rate was no higher using anchoring screw as an IMF than using arch bar fixation as an IMF. Mean surgical time was significantly shorter in the anchoring screw group than arch bar fixation (111 versus 157 min; P < .05). After compensation of the number of fracture sites, there was a significant difference in operation time (linear regression model, P = .009). CONCLUSION: This investigation revealed that the IMF using IMF screw systems could be a good alternative for the management of mandibular fracture. It could minimize the whole operation time with the similar complication ratio.

ABSTRACT

BACKGROUND: Recently, skin-redraping medial epicanthoplasty has emerged as an extremely effective way to minimize the resultant scar. We found that the novel skin-redraping medial epicanthoplasty technique, which has been applied to aesthetic surgery, could also be suitable for the correction of congenital epicanthus and telecanthus. METHODS: We retrospectively identified patients who had an epicanthoplasty from December 2007 to August 2017. Among 47 patients, we identified 19 cases with congenital pathologies (nonaesthetic cases). Overall, 7 patients with at least 2 anthropometric measurements were selected. RESULTS: There was a mean presurgical intercanthal distance of 35.85 mm (range, 24-52 mm) and a mean intercanthal distance of 26.85 mm (range, 17-36 mm) with a mean difference of 9 mm following postsurgical revision. To better categorize this difference, statistical analysis was conducted using a paired t test, which showed a significant result with P = 0.008. CONCLUSIONS: Our results revealed that the skin-redraping medial epicanthoplasty technique could be a better option even in the reconstruction of congenital telecanthus as well as aesthetic plastic surgery. It could correct mild to severe telecanthus and minimize scar formation.

ABSTRACT

BACKGROUND: Improving flap survival is essential for successful soft-tissue reconstruction. Although many methods to increase the survival of the distal flap portion have been attempted, there has been no widely adopted procedure. The authors evaluated the effect of flap preconditioning with two different modes (continuous and cyclic) of external volume expansion (pressure-controlled cupping) in a rat dorsal flap model. METHODS: Thirty rats were randomly assigned to the control group and two experimental groups (n = 10 per group). The continuous group underwent 30 minutes of preconditioning with -25 mmHg pressure once daily for 5 days. The cyclic group received 0 to -25 mmHg pressure for 30 minutes with the cyclic mode once daily for 5 days. On the day after the final preconditioning, caudally based 2 × 8-cm dorsal random-pattern flaps were raised and replaced in the native position. On postoperative day 9, the surviving flap area was evaluated. RESULTS: The cyclic group showed the highest flap survival rate (76.02 percent), followed by the continuous and control groups (64.96 percent and 51.53 percent, respectively). All intergroup differences were statistically significant. Tissue perfusion of the entire flap showed similar results (cyclic, 87.13 percent; continuous, 66.64 percent; control, 49.32 percent). Histologic analysis showed the most increased and organized collagen production with hypertrophy of the attached muscle and vascular density in the cyclic group, followed by the continuous and control groups. CONCLUSION: Flap preconditioning with the cyclic mode of external volume expansion is more effective than the continuous mode in an experimental rat model.

ABSTRACT

BACKGROUND: The mission of the International Confederation of Plastic Surgery Societies (ICOPLAST) is to improve patient outcomes through collaboratively structured processes in education, advocacy and communication. This article explains how we approached the task of establishing priorities for this nascent confederation in an equitable and achievable manner. METHODS: In late 2016, an online survey was sent to the inaugural 62 ICOPLAST member national societies for dissemination to their respective plastic surgeon members. Functional domains and proposed initiatives were ranked according to their level of importance by individual plastic surgeons. RESULTS: The survey was completed by 572 plastic surgeons. As a functional domain, education was highly ranked by 75.3% of respondents, followed by patient safety (67.4%), communication (59.3%), humanitarian (46.6%), regulation (41.2%), and advocacy (41.1%). Respondents also ranked individual initiatives within each domain to produce a compilation list of the top 13 initiatives of importance. CONCLUSION: This study has identified priorities of importance to ICOPLAST members, which will aid in building a strategic framework and enhancing outcomes for patients, plastic surgeons, and the field of plastic surgery more broadly.

ABSTRACT

OBJECTIVE: The purpose of this study was to determine whether test-retest nasalance score variability differs between Korean children with and without cleft palate (CP) and vowel context influences variability in nasalance score. PARTICIPANTS: Thirty-four 3-to-5-year-old children with and without CP participated in the study. METHODS: Three 8-syllable speech stimuli devoid of nasal consonants were used for data collection. Each stimulus was loaded with high, low, or mixed vowels, respectively. All participants were asked to repeat the speech stimuli twice after the examiner, and an immediate test-retest nasalance score was assessed with no headgear change. RESULTS: Children with CP exhibited significantly greater absolute difference in nasalance scores than children without CP. Variability in nasalance scores was significantly different for the vowel context, and the high vowel sentence showed a significantly larger difference in nasalance scores than the low vowel sentence. The cumulative frequencies indicated that, for children with CP in the high vowel sentence, only 8 of 17 (47%) repeated nasalance scores were within 5 points. CONCLUSIONS: Test-retest nasalance score variability was greater for children with CP than children without CP, and there was greater variability for the high vowel sentence(s) for both groups.

ABSTRACT

BACKGROUND: Although the harmony of facial proportions is traditionally perceived as an important element of facial attractiveness, there have been few objective studies that have investigated this esthetic balance using three-dimensional photogrammetric analysis. OBJECTIVES: To better understand why some women appear more beautiful, we investigated differences in facial proportions between beauty pageant contestants and ordinary young women of Korean ethnicity using three-dimensional (3D) photogrammetric analyses. METHODS: A total of 43 prize-winning beauty pageant contestants (group I) and 48 ordinary young women (group II) of Korean ethnicity were photographed using 3D photography. Numerous soft tissue landmarks were identified, and 3D photogrammetric analyses were performed to evaluate 13 absolute lengths, 5 angles, 3 volumetric proportions, and 12 length proportions between soft tissue landmarks. RESULTS: Group I had a greater absolute length of the middle face, nose height, and eye height and width; a smaller absolute length of the lower face, intercanthal width, and nasal width; a larger nasolabial angle; a greater proportion of the upper and middle facial volume, nasal height, and eye height and width; and a lower proportion of the lower facial volume, lower face height, intercanthal width, nasal width, and mouth width. All these differences were statistically significant. CONCLUSIONS: These results indicate that there are significant differences between the faces of beauty pageant contestants and ordinary young women, and help elucidate which factors contribute to facial beauty. The group I mean values could be used as reference values for attractive facial profiles. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

ABSTRACT

Background: To overcome the limited source of autogenous bone in bone grafting, many efforts have been made to find bone substitutes. The use of hybrid composites of silk and hydroxyapatite to simulate natural bone tissue can overcome the softness and brittleness of the individual components. Methods: Critical-sized, 7 x 4 x 1.5 mm alveolar defects were created surgically in 36 Sprague-Dawley rats. Three treatment groups were tested: an empty defect group (group I), a silk fibrin scaffold group (group II), and a hydroxyapatite-conjugated silk fibrin scaffold group (group III). New bone formation was assessed using computed tomography and histology at 4, 8, and 12 weeks, and semi-quantitative western blot analysis was done to confirm bone protein formation at 12weeks. Statistical analysis of new bone formation was done using the Kruskal-Wallis test. Results: Radiomorphometric volume analysis revealed that new bone formation was 64.5% in group I, 77.4% in group II, and 84.8% in group III (p=0.027) at 12 weeks. Histologically, the osteoid tissues were surrounded by osteoblasts not only at the border of the bone defect but in the center of the scaffold implanted area in group III from week 8 on. Semi-quantitative western blotting revealed that osteocalcin expression in group III was 1.8 times higher than group II and 2.6 times higher than group I. Conclusions: New bone formation was higher in hybrid scaffolds. Both osteoconduction at the defect margin and osteoinduction at the center of the defect were confirmed. There were no detected complications related to foreign body implantation.

ABSTRACT

INTRODUCTION: LeFort III midface advancement using the distraction technique became the standard method for the correction of various craniofacial syndromes accompanied by the midface retrusion. Midface hypoplasia is known to be related to the imbalance in facial aesthetics, malocclusion, and the airway problem. This study aimed to evaluate the change in airway volume after performing a LeFort III midface advancement with the distraction techniques. PATIENTS AND METHODS: Between April 2008 and February 2013, 7 patients aged 5 to 7 years underwent standard LeFort III osteotomy, followed by distraction with a rigid external distractor with or without internal distractor. The degree of advancement of the midface and the airway volume were evaluated with 3-dimensional computed tomography scans and the 3-dimensional software. RESULTS: The average latent period was 3.57 days. The average manual distraction distance was 17.55 mm for 3.82 weeks. The consolidation period ranged from 3 to 7 months. Changes between the preoperative and postoperative airway volumes were remarkable. The average preoperative postpharyngeal airway volume was 5649.33 mm compared with an average postoperative airway volume of 7403.44 mm. Therefore, the average postpharyngeal airway space increased by a remarkable 32.78%. CONCLUSIONS: This investigation revealed that the LeFort III midface advancement using distraction could increase postpharyngeal airway space by approximately 33% when the midface is advanced by approximately 18 mm. This method could be used as a future reference for LeFort III midface advancement with distraction.

ABSTRACT

BACKGROUND: The purpose of this study is to investigate the differences in the periorbital anthropometry between national Beauty Pageant Contestants and Ordinary Young Women with Korean ethnicity. METHODS: Forty-three Beauty Pageant Contestants who were elected for the national beauty contest and forty-eight Ordinary Young Women underwent 3D photography. The authors analyzed 3D photogrammetric measures regarding periorbital soft tissue. RESULTS: The palpebral fissure width was significantly higher in the Beauty Pageant Contestants than the Ordinary Young Women (27.7 ± 1.2 vs. 26.3 ± 1.6 mm) (p < 0.001). The palpebral fissure height was also significantly higher in the Beauty Pageant Contestants (11.5. ± 1.0 vs. 9.1 ± 1.2 mm) (p < 0.001). The intercanthal width and upper eyelid height were smaller for the Beauty Pageant Contestants (intercanthal width, 34.3 ± 1.86 mm vs. 36.7 ± 3.1 mm; upper eyelid height, 11.5 ± 1.4 mm vs. 13.4 ± 2.3 mm) (p < 0.05). The nasal width and midfacial width were significantly smaller in the Beauty Pageant Contestants (nasal width, 38.0 ± 1.8 vs. 39.5 ± 2.2 mm; midfacial width 144.5 ± 3.9 vs. 146.9 ± 5.2 mm) (p < 0.05). The eyebrow showed significantly different features between the two groups in terms of vertical position in the upper face and the shape of the brow apex. The interpupillary distance, binocular distance, slant of palpebral fissure and width of pretarsal crease showed no significant difference between the two groups. CONCLUSION: Periorbital features in Beauty Pageant Contestants are wide-set eyes, larger palpebral fissure in width and height, relatively small upper eyelid height and intercanthal width, and relatively small nose and facial width compared to normal women. Our anthropometric results can be referable values for Asian eyelid surgery and help surgeons to establish individualized surgical planning.
