Abstract
OBJECTIVE To determine if the elastic chain premaxillary retraction (ECPR) appliance increases inter-medial and inter-lateral canthal dimension in patients with bilateral complete cleft lip and palate (BCLP). DESIGN Retrospective cohort study. SETTING Specialized tertiary care facility. PATIENTS, PARTICIPANTS 126 patients with BCLP; 75 had ECPR, 51 had no pre-surgical manipulation. INTERVENTIONS Three-dimensional facial photographs were obtained prior to insertion of appliance (T0), post-appliance therapy prior to appliance removal/labial repair (T1), and several months after labial repair (T2) for a longitudinal ECPR group, and were obtained after age 4 years (T3) for a non-longitudinal ECPR group and for the non-ECPR group. MAIN OUTCOME MEASURES Inter-medial and inter-lateral canthal dimension (en-en, ex-ex) was determined for all groups/time-points. Measurements were compared between groups and to norms. RESULTS The mean en-en and ex-ex was 32.6 ± 3.2 mm and 84.4 ± 6.3 mm for the ECPR group and 33.5 ± 3.1 mm and 86.7 ± 7.2 mm for the non-ECPR group at T3. Inter-medial and inter-lateral canthal dimensions were significantly greater than normal (P < .05) in both groups; there was no significant difference between groups (P > .05). The mean en-en and ex-ex for the Longitudinal ECPR group was 27.5 ± 2.4 mm and 66.7 ± 3.7 mm at T0, 29.6 ± 2.4 mm and 70.4 ± 2.9 mm at T1, and 29.2 ± 2.3 mm and 72.3 ± 3.8 mm at T2. en-en and ex-ex increased significantly from T0-T1 (P < .05), decreased at T2 (P > .05) and was significantly larger than normal at all time-points (P < .05). CONCLUSIONS Inter-medial and inter-lateral canthal dimension increased after ECPR but returned to baseline growth trajectory. These dimensions were above normal at all time-points. There was no difference between those that did and did not have dentofacial orthopedic manipulation.

[PMID: 37511680 PMCID: PMC10381611 DOI: 10.3390/jpm13071067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 07/30/2023] Open
Abstract
Facial asymmetry is common in unilateral clefts. Since virtual surgical planning (VSP) is becoming more common and automated segmentation is utilized more often, the position and asymmetry of the orbits can affect the design outcome. The aim of this study is to evaluate whether non-syndromic unilateral cleft lip and palate (UCLP) patients requiring orthognathic surgery have asymmetry of the bony orbits. Retrospectively, we analyzed the preoperative cone-beam computed tomography (CBCT) or computed tomography (CT) data of UCLP (n = 15) patients scheduled for a Le Fort 1 (n = 10) or bimaxillary osteotomy (n = 5) with VSP at the Cleft Palate and Craniofacial Center, Helsinki University Hospital. The width, height, and depth of the bony orbit and the distance between the sella turcica and infraorbital canal were measured. A volumetric analysis of the orbits was also performed. The measurements were tested for distribution, and the cleft side and the contralateral side were compared statistically with a two-sided paired t-test. To assess asymmetry in the non-cleft population, we performed the same measurements of skeletal class III patients undergoing orthognathic surgery at Päijät-Häme Central Hospital (n = 16). The volume of bony orbit was statistically significantly smaller (p = 0.014), the distance from the infraorbital canal to sella turcica was shorter (p = 0.019), and the anatomical location of the orbit was more medio-posterior on the cleft side than on the contralateral side. The non-cleft group showed no statistically significant asymmetry in any measurements. According to these preliminary results, UCLP patients undergoing orthognathic surgery show asymmetry of the bony orbit not seen in skeletal class III patients without a cleft. This should be considered in VSP for the correction of maxillary hypoplasia and facial asymmetry in patients with UCLP.

Abstract
Growth alterations have been described in patients operated on for oral clefts. The purpose of this work was to analyze the craniofacial and palate morphology and dimensions of young adults operated on for oral clefts in early childhood in Spain. Eighty-three patients from eight different hospitals were divided into four groups based on their type of cleft: cleft lip (CL, n = 6), unilateral cleft lip and palate (UCLP, n = 37), bilateral cleft lip and palate (BCLP, n = 16), and cleft palate only (CPO, n = 24). A control group was formed of 71 individuals. Three-dimensional (3D) digital models were obtained from all groups with an intraoral scanner, together with cephalometries and frontal, lateral, and submental facial photographs. Measurements were obtained and analyzed statistically. Our results showed craniofacial alterations in the BCLP, UCLP, and CPO groups with an influence on the palate, maxilla, and mandible and a direct impact on facial appearance. This effect was more severe in the BCLP group. Measurements in the CL group were similar to those in the control group. Cleft characteristics and cleft type seem to be the main determining factors of long-term craniofacial growth alterations in these patients. Prospective research is needed to clearly delineate the effects of different treatments on the craniofacial appearance of adult cleft patients.

Abstract
Ocular ultrasound is an invaluable tool for the evaluation of the eye and orbit. However, the eye and orbit are potentially sensitive to the thermal and mechanical effects of ultrasound. When performing B-mode imaging, dedicated ocular settings should be used. If these settings are not available, limiting the acoustic output to Food and Drug Administration (FDA) recommended maximum levels is strongly advised. Especially important is the acoustic output in spectral (pulsed) and color Doppler modes, which can exceed the FDA's maximum recommended levels for the eye. Adjusting settings to decrease acoustic output and limiting the time of the examination should be done when performing a Doppler examination. The acoustic output of shear wave elastography is significantly higher than FDA guidelines for the eye and should be considered experimental.

Abstract
The interocular distance, or orbital telorism, is a distinctive craniofacial trait that also serves as a clinically informative measure. While its extremes, hypo- and hypertelorism, have been linked to monogenic disorders and are often syndromic, little is known about the genetic determinants of interocular distance within the general population. We derived orbital telorism measures from cranial magnetic resonance imaging by calculating the distance between the eyeballs’ centre of gravity, which showed a good reproducibility with an intraclass correlation coefficient of 0.991 (95% confidence interval 0.985–0.994). Heritability estimates were 76% (standard error = 12%) with a family-based method (N = 364) and 39% (standard error = 2.4%) with a single nucleotide polymorphism-based method (N = 34 130) and were unaffected by adjustment for height (model II) and intracranial volume (model III) or head width (model IV). Genome-wide association studies in 34 130 European individuals identified 56 significantly associated genomic loci (P < 5 × 10−8) across four different models of which 46 were novel for facial morphology, and overall these findings replicated in an independent sample (N = 10 115) with telorism-related horizontal facial distance measures. Genes located nearby these 56 identified genetic loci were 4.9-fold enriched for Mendelian hypotelorism and hypertelorism genes, underlining their biological relevance. This study provides novel insights into the genetic architecture underlying interocular distance in particular, and the face in general, and explores its potential for applications in a clinical setting.

Unilateral Cleft Lip Nasal Deformity: Three-Dimensional Analysis of the Primary Deformity and Longitudinal Changes following Primary Correction of the Nasal Foundation.

Abstract
BACKGROUND Objective assessment of the unilateral cleft lip nasal deformity and the longitudinal changes with treatment is critical for optimizing cleft care. METHODS Consecutive patients undergoing cleft lip repair and foundation-based rhinoplasty were included (n = 102). Three-dimensional images preoperatively, postoperatively, and at 5 years of age were assessed and compared to age-matched controls. Images were normalized to standard horizontal, craniocaudal, and anteroposterior axes. RESULTS Cleft subalare was similar in position relative to controls but was 1.6 mm retrodisplaced. Subnasale was deviated 4.6 mm lateral to midline and had the greatest displacement of any landmark. Noncleft subalare was displaced 2.3 mm laterally. Regression analysis with deviation of subnasale from the midline as a dependent variable revealed progressive lateral displacement of noncleft subalare, narrowing of noncleft nostril, and intercanthal widening. Surgery corrected nasal base displacements along all axes, resulting in landmark positions similar to controls. Symmetry of nasal base correction persisted at 5-year follow-up, with no recurrent cleft alar base retrusion, regardless of initial cleft type. CONCLUSIONS Unilateral cleft lip nasal deformity may be "driven" by displacement of the anterior nasal spine and caudal septum. The cleft alar base is normal in position but retruded, whereas the noncleft alar base is displaced laterally. Changes with surgery involve anterior movement of the cleft alar base but also include medial movement of the noncleft alar base and columella. Symmetry of correction, including alar base retrusion, was stable over time and did not rely on alveolar bone grafting.

Abstract
INTRODUCTION Datasets of soft-tissue craniofacial anthropometric norms collected with the use of different methods are available, but there is little understanding of how the measurements compare. Here we compare a set of standard facial measurements between 2 large datasets: the 3D Facial Norms (3DFN) dataset collected with the use of 3D stereophotogrammetry (n = 2454), and the Farkas craniofacial norms collected with the use of direct anthropometry (n = 2326). METHODS A common set of 24 craniofacial linear distances were compared by computing standardized effect sizes (Cohen d) for each measurement to describe the overall direction and magnitude of the difference between the 2 datasets. RESULTS Variables with higher mean d values (suggesting greater discrepancy across datasets) included measurements involving the ear landmark tragion, the landmark nasion, the width of nasolabial structures, the vermilion portion of the lips, and palpebral fissure length. Variables with lower mean d values included smaller midline measurements involving the lips and lower face and horizontal distance measures between the eyes. Eight measurements showed a significant negative correlation (P < 0.05) between Cohen d and age, indicating greater similarity across the 2 datasets as age increased. CONCLUSIONS There are considerable differences between the 3DFN and Farkas norms. In addition to the measurement methods, other factors accounting for discrepancies may include secular trends in craniofacial morphology or differences in ethnic composition.
