Facial asymmetry outcome of orthognathic surgery in mild craniofacial microsomia compared to non-syndromic class II asymmetry

ObjectivesTo compare the facial asymmetry after bimaxillary surgery between mild craniofacial microsomia (CFM) and non-syndromic class II asymmetry.Materials and methodsCone-beam computed tomography scans of adults with Pruzansky-Kaban types I and IIA CFM (CFM groups, n = 20), non-syndromic skeletal class II asymmetry (Class II group, n = 20), and normal controls (control group, n = 20) were compared. The area asymmetry of lower face and jaw bones was quantified. Landmark-based method was used to evaluate the lower facial asymmetry regarding midline, cants, and contour.ResultsThere were no significant postoperative differences in the hemi-facial and hemi-jaw area asymmetry between CFM and Class II groups, both of which were significantly larger than the control group. No significant difference was found in the midline deviation and lip and occlusal cants between CFM and Class II groups. The vertical contour asymmetry in CFM group became significantly larger than Class II group. Compared to the control group, the deviation of pronasale, subnasale, and soft-tissue menton, lip and occlusal cants, and sagittal and vertical contour asymmetry in CFM group were significantly larger, as were the deviation of subnasale and soft-tissue menton and vertical contour asymmetry in Class II group.ConclusionsThe vertical contour asymmetry of mild CFM was significantly larger than non-CFM class II after surgery, while the area asymmetry, midline deviation, cants, and sagittal contour asymmetry of lower face showed no significant difference.Clinical relevanceBe aware that correcting vertical asymmetry of contour, lip, and dentition in CFM is still challenging.

Maxillary transverse discrepancy: Latest innovations in diagnosis and treatment planning

Transverse length related malocclusions are common in orthodontic clinics. They can be as simple as posterior crossbite or as severe as Class III malocclusion, where the jaw is asymmetrical. Cases of lateral malocclusion range from simple alveolar problems to complex problems such as bone asymmetries that occur after adolescence and lead to temporomandibular joint disorder (TMD). This is a review article to discuss types of transverse malocclusions and most latest innovations in diagnosis and treatment planning. Many methods of diagnosis and correcting maxillary transverse discrepancies have been discussed. Orthodontists should know about the drawbacks of each method.

Comparison of the efficacy of fat, cartilage, and bone grafts in traumatic and asymmetric noses

BackgroundCorrection of asymmetry and irregularity deformities with autologous grafts, without osteotomies, offers advantages to both plastic surgeons and patients with severe deviation. Various autologous tissues such as fat, bone, and cartilage grafts are viable options for this purpose. ObjectivesThis study aims to compare the efficacy of three autologous filling materials in patients with bone asymmetry. MethodsA retrospective evaluation was conducted on 297 patients seeking aesthetic nose surgery between 2015 and 2022. Only primary patients without prior surgery, those with bone asymmetry from trauma, dorsum protrusion less than 3 mm, and no osteotomy were included. Patients were divided into fat, cartilage, and bone groups. Grafts were applied to the concave side during closed rhinoplasty, and evaluations were done at 12 months post-surgery by blinded plastic surgeons and patients using established assessment tools. ResultsFat, cartilage, and bone grafts were utilized in 74, 127, and 96 patients respectively, with mean follow-up of 19 months. Mean graft volumes were 1.0 cc (bone), 1.3 cc (cartilage), and 1.6 cc (fat). Patient self-assessment scores were 75%, 84.9%, and 86.6% respectively. Asher-McDade averages were 77.2%, 86.7%, and 88.4%. Cartilage and bone graft results were statistically similar in patient self-evaluation, both significantly higher than fat grafts. Blinded assessments showed no significant difference between cartilage and bone groups. ConclusionPlacing autologous grafts on the concave side for patients with minimal nasal bone protrusion (<3 mm) yields successful results. Cartilage grafts offer advantages in volume, result estimation, and preparation time, suitable for larger patient cohorts.

Inter-arm bone mass and size asymmetries in children tennis players are maturity status specific: a 9-month study on the effects of training time across pubertal change and somatic growth

PurposeBone growth with exercise is best assessed by tennis-induced inter-arm asymmetries. Yet, the effects of training and maturation across puberty were unclear. This study explored arm bone growth across 9 months of training in 46 tennis players 7–14 years (25 boys, 21 girls).MethodsBone mineral content (BMC) and bone area (BA) were measured from DXA scans. Pubertal status was assessed by Tanner stage (TS) and somatic growth by maturity offset (MO). Children were grouped as pre- (TS I–I), early (TS I–II), and mid/late pubertal (TS II–III).ResultsTraining time (TT) change in the three groups was 160–170, 190–230, and 200–220 h, respectively. Bone asymmetries were large in all groups (d > 0.8, P < 0.001): 5–18 g (9–21%) and 9–17 g (17–23%) in girls and boys, respectively, for BMC, and 5–15 cm2 (6–13%) and 9–15 cm2 (12–15%) in girls and boys (10–13%), respectively, for BA. BMC and BA change asymmetry peaked at pre-puberty in girls (56%, 46%) and at early puberty in boys (57%, 43%). Asymmetry gains varied with baseline asymmetry (41%) and change in TT (38%) and TS (17%) in BMC, and with baseline asymmetry (58%) and change in MO (17%) and TS (12%) in BA.ConclusionAll bone asymmetries were substantial. Tennis-induced bone gains were higher at pre- to early puberty in girls and at early to mid/late puberty in boys. Training enhanced mostly bone mass and maturity status enhanced mostly bone size; sex was not bone-change modeling impactful. Implications are discussed considering certain limitations.

Piezo1 mutant zebrafish as a model of idiopathic scoliosis.

Scoliosis is a condition where the spine curves sideways, unique to humans due to their upright posture. However, the cause of this disease is not well understood because it is challenging to find a model for experimentation. This study aimed to create a model for human idiopathic scoliosis by manipulating the function of mechanosensitive channels called Piezo channels in zebrafish. Zebrafish were chosen because they experience similar biomechanical forces to humans, particularly in relation to the role of mechanical force in scoliosis progression. Here we describe piezo1 and piezo2a are involved in bone formation, with a double knockout resulting in congenital systemic malformations. However, an in-frame mutation of piezo1 led to fully penetrant juvenile-onset scoliosis, bone asymmetry, reduced tissue mineral density, and abnormal intervertebral discs-resembling non-congenital scoliosis symptoms in humans. These findings suggest that functional Piezo channels responding to mechanical forces are crucial for bone formation and maintaining spine integrity, providing insights into skeletal disorders.

Investigating crossed-symmetry pattern in children from the past

In biological anthropology, bilateral asymmetry in living adult samples is a well-studied field. During the last decade, researchers have become more interested in its developmental characteristics in individuals of both living and past populations. It is still the upper limb that gets attention, as handedness and its effects on the bones via biomechanical loading is an obvious and easily measurable marker of bilateral asymmetry. The majority of the population exhibit right bias in the measurements of the upper limb bones and the lower limb behaves the opposite due to its performance in weight- bearing. This pattern is called crossed-symmetry. Despite its marked role in posture, examining the emergence of lower limb bone asymmetry during growth has not been well-researched. To add more information to this field, the present study investigated the developmental pattern of lower limb bone bilateral asymmetry in medieval Hungarian children from one of the country’s biggest anthropological collections.

Radiographic Assessment of Bilateral Asymmetry in the Upper Extremities of Living Humans.

Objective Injuries resulting from trauma or tumor resection may cause length alterations in the bones of the upper extremities (UE) requiring reconstruction. Direct contralateral bone is often used to determine the appropriate length for reconstructionbut fails to account for potential asymmetry. Given the paucity of data assessing asymmetry in living populations and the need for accurate length approximation, we developed a study evaluating UE long bone asymmetry using radiographic imaging in living subjects. Methods Bilateral X-ray images previously obtained for traumatic injury or chronic osseous conditions were retrospectively collected for adult subjects (ages 18-81). After screening, 61 patients met the inclusion criteria: 28 radii, 29 ulnae, and 19 humeri. Three serial measurements were taken, and the median was used for subsequent analysis. Wilcoxon signed-ranktests were performed to assess differences in contralateral bone lengths. Bootstrapping was utilized to obtain sample sizes of 200, 500, and 1000 for each bone. Results The difference in mean absolute length was 27.0 mm for the humerus, 8.6 mm for the radius, and 7.5 mm for the ulna. Neither the left side nor the right side was significantly longer for any bone. In 57.9% (11/19) of patients, the right humerus was longer than the left; in 60.7% (17/28), the right radius was longer than the left; and in 48.3% (14/29), the right ulna was longer than the left. All other measurements showed the left was longer than the right. Wilcoxon signed-rank tests did not find significant differences between contralateral pairs in any direct measurement group. In bootstrap samples, significant differences in length (p ≤ 0.05)were seen in all samples (n = 200, 500, and 1000) for both humerus and radiusbut only the 1000 sample group for the ulna. Conclusions Direct contralateral measure may be an appropriate method of length estimation for the humerus, radius, and ulna in post-industrial humans.

Three-dimensional Analysis of the Temporal Bone Morphology in Patients with Craniofacial Microsomia.

To characterise the morphology of temporal bone in patients with craniofacial microsomia (CFM). A retrospective study. A craniofacial centre. Ninety-four patients with unilateral craniofacial microsomia. Mimics 21.0 (Materialise Inc., Belgium) was used to locate temporal bone landmarks on preoperative computed tomography data. The spatial Cartesian coordinate system was established in 3-matic 13.0 (Materialise Inc., Belgium). The coordinates of each landmark and the distances and angles between the landmarks were calculated. A classification system was used to quantify the severity of the zygomatic arch deformity. The bilateral differences in coordinates, linear and angular measurements, and the severity of temporal bone deformity (TTL δ, Psag δ, Paxiδ, and Tsag δ) among the groups were compared using the paired t-test and Kruskal-Wallis test, respectively. Compared to those of the unaffected side, the landmarks of the inner ear and petrous part on the affected side showed a decrease in the Z-coordinate or an increase in the X-coordinate. A superolateral rotation tendency of the temporal bone on the affected side was found. There were no significant differences in the linear and angular measurements between the groups. The degree of zygomatic arch deformation was lower in the mild group; however, no significant difference was found between the moderate and severe groups. In patients with CFM, asymmetry of the temporal bone and its inner organs (vestibulocochlear organ, facial nerve, and vessels) exists in multiple dimensions; its severity is not completely consistent with the degree of mandibular involvement.

Evaluations and Measurements of the Occurrence of Maxilla and Palatine Bone Asymmetry Based on 3D Printed Stereolithographic Models in Elderly Edentulous People

This study aimed to evaluate and measure the occurrence of jaw and palate asymmetry based on 3D-printed stereolithographic models of edentulous elderly people. The analyses were performed on 3D models of the jaws, which were printed using the data (CT) obtained from the CBCT center. The control group consisted of 10 modern adult skulls (7 male and 3 female skulls) owned by the Department of Anthropology of the Wrocław University of Environmental and Life Sciences. The small size of the studied groups did not allow for the performance of the analysis indicating the form of the observed morphological asymmetry—it was impossible to differentiate to indicate whether the examined features showed directional or fluctuating asymmetry. However, it was possible to determine the direction of the morphological asymmetry of the analyzed features. Both in the test group and the control group, it was a right-sided asymmetry. The analysis of the significance of differences in mean values of the asymmetry index showed that the intensity of asymmetry of the anterior part of the superior alveolar arch was significantly greater in the test group. The severity of the asymmetry of the lateral part of the alveolar arch in the tested groups did not differ significantly. The authors concluded that adequate maxillary height does not only influence proper dental prosthesis adhesion but also corresponds with a potential source for correct dental implant placement. We also concluded that the vertical height of the edentulous alveolar process of the mandible is important for adequate prosthesis fixing. In some cases, the bone atrophy and the bone itself are asymmetrical, so planning a prosthesis might be challenging. The adequate placement of implants should include the symmetry of jaw bones because of future masticatory force impact on the bone and the entire masticatory system, including the temporomandibular joint.

MANAGEMENT OF A MAXILLO-ZYGOMATIC FIBROUS DYSPLASIA IN A GROWING-UP CHILD: EIGHT YEARS’ FOLLOW-UP CASE REPORT

Fibrous dysplasia (FD) is a benign dysplastic disorder of bone development in which the normal bone matrix is replaced by fibroblastic proliferation. The aim of this case report is to report a case of a 12-year-old White male patient who was referred to an oral and maxillofacial surgery service with the main complaint of facial asymmetry and tumefaction in the right maxillo-zygomatic region. Physical examination, computed tomography, and incisional biopsy were performed, which confirmed the diagnosis of FD. A stereolithographic model was generated to manufacture a surgical guide. Osteoplasty was conducted under general anesthesia and the patient was follows up every 6 months after surgery. After 8 years of follow-up, a positive control of facial asymmetry, contour, and volume of bone affected were achieved. Final computed tomography showed that the maxilla and zygomatic bones increased in size and volume, with no compression of important structures and no functional damage.

North American River Otters Exhibit Direction Asymmetry in Limb Bone Shape

The occurrence of handedness has been widely observed and studied among humans. There is evidence that suggests the asymmetric pressures of using one limb more prominently can have a developmental effect on bone size and shape. The correlation of handedness with directional asymmetry of limb bones has propagated the question of whether this instance also occurs across the animal kingdom, especially within species that use their limbs to move and manipulate objects. Using the North American River Otter (Lontra canadensis), we compared differences in bone size and shape of the left and right limbs. The assessments were made by taking a variety of length and width measurements, as well as integrating 3D geometric morphometrics to compare the bone profiles. Using a t‐test, we found non‐significant (p&gt;.05) differences in the length and width measures of the left and right bones. However, results of an ANOVA on Procrustes aligned shape coordinates indicate significant (p&lt;.05) differences in bone shape. Our results suggest that the shape of left and right limb elements in both the forelimb and hindlimb illustrate directional asymmetry. Future research will provide insight as to whether the shape asymmetry is a product of handedness or other environmental factors.

Bone health and asymmetry in elite female cricketers

ABSTRACT The aim of this study is to determine if bone mineral density (BMD) and bone asymmetry differs between female cricket fast bowlers, spin bowlers and batters. BMD was determined at the total body, lumbar spine, and proximal femurs in 12 fast bowlers, 13 batters and 11 spin bowlers from pre-season DXA scans. High Z-scores at the total body, lumbar spine, and proximal femur were observed in all cricketers (mean Z-scores: +1.4 to +3.3) compared with a general age matched reference population. Fast bowlers had significantly greater BMD on the contralateral side of the lumbar spine compared with the ipsilateral side (p = 0.001, 5.9–12.1%). No asymmetry was found between hips in all groups. All cricket positions demonstrated high BMD at all measured sites. The lumbar spine of fast bowlers is asymmetric, with significantly greater BMD on the contralateral side of the spine, particularly at L4, possibly in response to the asymmetric lumbar loading patterns observed in bowling. Highlights Elite female cricketers demonstrate high BMD at total body, lumbar spine and proximal femur sites, regardless of playing position compared with a general age and ethnic group matched reference population. Fast bowlers have greater BMD on the contralateral (opposite bowling arm) side of the lumbar spine compared with the ipsilateral side, while a symmetrical pattern was observed in spin bowlers and batters. No asymmetry in BMD or section modulus between hips was observed at any proximal femur site for any cricket position.

ВОЗМОЖНОСТИ ДИАГНОСТИКИ И КУРАЦИИ ПАТОЛОГИИ ВИСОЧНО-НИЖНЕЧЕЛЮСТНОГО СУСТАВА НА ФОНЕ ГИПЕРТОНУСА ЖЕВАТЕЛЬНЫХ МЫШЦ У ЛИЦ С СИСТЕМНОЙ ДИСПЛАЗИЕЙ СОЕДИНИТЕЛЬНОЙ ТКАНИ

Systemic dysplasia is a formation pathology of the connective tissue structures. With a high prevalence of systemic connective tissue dysplasia (SCTD), the insufficient awareness of doctors about the possibilities of its early diagnosis and correction, starting from the stage of pediatric care, draws attention. Progressive asymmetries of the skeleton already from childhood lead to additional trauma of all genetically determined, but at the same time defective connective tissue structures. The aim of the work was to improve the efficiency of diagnosis and treatment of diseases of the temporomandibular joint (TMJ) in persons with SCTD. The results of a study of 507 patients of different ages are presented. Comparative radiography of the lower extremities reveals a row of pathological changes in the hip and knee joints, the difference in the length of the femurs, lower legs; the height of the iliac wings, scoliosis of the lumbar spine, allowing us to consider them as a complex of Short Leg Syndrome in the framework of SCTD. Asymmetries of the bone structures of the lower jaw are often aggravated by hypertonicity of the masticatory muscles. According to the results of radiological examination, various bone asymmetries of the maxillofacial region (MFR), of the lower extremities within 5–15 mm of relative length, centric jaw relation abnormalities, pathological changes in the masticatory muscles, dislocation of the TMJ articular disc, positional asymmetry of the external auditory canals were revealed. The information obtained allows us to construct a diagnostic algorithm. Ultrasound of the heart, abdominal organs, and kidneys in a standing position were performed to diagnose visceral signs of SCTD. The methods of diagnosis of skeletal asymmetries include: orthopantomography (OPTG) of the MFR, transoral radiography of C1-C2, comparative radiography of the lower extremities, computed tomography and conebeam computed tomography of the MFR capturing the structures of the joint and three upper cervical vertebrae, magnetic resonance imaging of the TMJ. Bone asymmetries are combined with asymmetries of muscle structures, increasing postural imbalance. Multiple anatomical incongruences are aggravated by muscular imbalance in the TMJ biomechanics, which, in the context of systemic connective tissue dysplasia, significantly complicates standard treatment tactics, and worsens the prognosis and remote catamnesis.

Musicians’ medicine – potential health problems among violinists and violists caused by playing the string instrument – the review of the literature

Introduction and purpose&#x0D; Musicians' medicine has received increasing attention recently. It is known that listening to music or playing an instrument has beneficial effects on cognitive and neural functions. Playing the string instrument demands repetitive precise movements of fingers and arms in a non-ergonomic posture that might give rise to health problems.&#x0D; The study aims to present the current state of knowledge regarding different potential health problems among violinists and violists. The article reviews the 24 newest scientific publications available on PubMed and Google Scholar.&#x0D; A brief description of the state of knowledge&#x0D; The literature review indicated several potential health consequences of excessive playing the violin or viola, as follows: Fiddler's neck and skin allergy, Garrod’s pads, temporomandibular disorders, carpal tunnel syndrome, cubital tunnel syndrome, tennis elbow, compression of the right ulnar nerve in the ulnar (Guyon's) canal, rotator cuff tendonitis, tenosynovitis, bursitis, focal dystonia, thoracic outlet syndrome, bone asymmetry, pain in the neck, cheeks, fingers, wrist, forearm, shoulder, waist, and the back.&#x0D; Conclusions &#x0D; Musicians should be aware of potential health problems that occur during prolonged playing the violin or the viola. An important issue is maintaining the accurate proportions between the amount of time spent playing the instrument and resting. The first signs of neurological or musculoskeletal changes should prompt the musician to seek professional medical help to prevent the disorder's progression.

Intranasal meningoencephalocele in a 1‐year‐old Staffordshire Bull Terrier with unilateral destructive rhinitis

AbstractAn 18‐month‐old male neutered Staffordshire Bull Terrier presented for chronic sneezing, left‐sided rhinorrhea and epistaxis associated with previous nasal planum depigmentation and pruritus. Physical examination did not demonstrate bone asymmetry or depigmentation, but showed reduced airflow through the left nostril. No neurologic abnormalities were present. CT identified severe destruction of the left nasal turbinates and defect of the left cribriform plate, with protrusion of the left olfactory lobe into the caudal part of the nasal cavity. Rhinoscopy did not identify fungal plaques or foreign material, and nasal biopsies were consistent with lymphoplasmacytic destructive rhinitis. Tissue cultures were negative. Clinical signs completely resolved after 2 weeks of doxycycline treatment and did not recur. There was no development of neurologic abnormalities in the 12 months after diagnosis. This is the first case report of canine meningoencephalocele presenting with rhinitis‐associated signs without detectable neurologic abnormalities.

The Volume Difference Along the External Surface of the Zygomatic Bone: A Novel Method of Measuring Zygomatic Bone Asymmetry.

This study introduced the volume difference along the external surface (VDAES) of the zygomatic bone as a novel approach to assess zygomatic bone asymmetry and was the first to describe a distinctive, 4-step method of measuring it. VDAES has a potential to be used as an objective tool to evaluate dislocation and can assist surgeons in predicting risks of long-term cosmetic complications in patients with zygomaticomaxillary complex fractures. After having measured 100 healthy study participants, the observed median VDAES was 1.48 cm3 for all study participants, 2.02 cm3 for males, and 1.09 cm3 for females, with the gender difference being significant (P = 0.003). Additional studies are needed to test the hypothesis of whether VDAES is more relevant than conventional methods of clinically evaluating zygomatic bone asymmetry.

The Effect of the Repair of Induced Articular Cartilage Defects in Pigs Using Calcium Phosphate Cement with Aminoacids on the Concentrations of Selected Inflammatory Markers and Serum Enzyme Activities

The repair of articular cartilage defects is an intensively developing area of research. Severe inflammatory reactions after surgical interventions on bones or their structures may lead to changes of bone or joint asymmetry. In laboratory diagnostics, some inflammatory biomarkers and serum enzymes are available for the evaluation of these inflammatory processes. A general understanding of inflammatory responses following the repair of cartilage defects is still lacking. The aim of this study was to describe the alterations in the values of five inflammatory markers and the activities of several enzymes in seven 5-month-old pigs within the first 30 days following the restoration of induced articular cartilage defects using the tetracalcium phosphate/nanomoneite cement powder enriched with amino acids (CAL). The reconstruction of surgically induced defects was accompanied by a significant increase of serum amyloid A (SAA, p &lt; 0.05), haptoglobin (Hp, p &lt; 0.001), C-reactive protein (CRP, p &lt; 0.01), and pig major acute phase protein (pig-MAP, p &lt; 0.001). Their concentrations decreased gradually within one-month post-surgery, the values recorded at the end of this period were higher than those obtained prior to surgery. The concentrations of α1-acid glycoprotein (AGP) showed no significant changes during the evaluated period. Alterations were also found in the enzyme activities of creatine kinase (p &lt; 0.05), lactate-dehydrogenase and alkaline phosphatase (p &lt; 0.01). These findings suggest that SAA, Hp, CRP and pig-MAP might be applicable biomarkers of acute phase response for the monitoring of postoperative period.

Three‐dimensional analysis of the temporal bone and mandibular morphology in mandibular prognathism with facial asymmetry

AbstractThe aims of this study were to perform a three‐dimensional analysis of the craniofacial area, in particular, the temporal bone and to examine the morphological relationship between the temporal bone and asymmetry of the mandible in subjects with mandibular prognathism and facial asymmetry. Subjects were 50 adult orthognathic patients with facial asymmetry and mandibular prognathism. The initial computed tomographic data were reconstructed into three‐dimensional and multiplanar reconstruction images. Linear and angular measurements of the temporal bone and the mandible were obtained. Then deviated and non‐deviated sides were compared and the relationship between the temporal bone and mandibular morphology was investigated. The lengths of the mandibular body and ramus, the anteroposterior and vertical positions of the mandibular fossa, and the slant angle of the posterior surface of the petrous pyramid were significantly smaller (P &lt; .05) on the deviated side than on the non‐deviated side. Further, the left‐right differences in the temporal bone were positively correlated with a deviation of the mandible and differences in the lengths of the mandibular body and ramus (P &lt; .05). The results suggest that asymmetry of the temporal bone is closely related to mandibular asymmetry and might have an important role in the mechanism of facial asymmetry.

Minimally Invasive Single-Point Stabilization of Zygomaticomaxillary Complex Fractures.

This study aimed to present a minimally invasive surgical management of zygomaticomaxillary complex (ZMC) fractures with reduction and single-point stabilization over the frontozygomatic buttress. This prospective cohort study was conducted on cases of ZMC fractures. The inclusion criteria were displaced tetrapod zygomatic factures, asymmetry of the facial bones, and unilateral lesion. The exclusion criteria were extensive skin or soft tissue loss, comminuted inferior orbital rim, limited ocular mobility, and enophthalmos. Surgical management included reduction and single-point stabilization over the zygomaticofrontal suture with miniplates and screws. The outcome measure was correction of the clinical deformity with less scarring and low postoperative morbidity. The late outcome was maintenance of a stable fixed reduced zygoma over the follow-up period. Forty-five patients were included in the study with a mean age of 30 ± 5.56years. The study included 40 men and 5 women. Motor vehicle accident was the most common cause of fracture (62.2%). They were managed via lateral eyebrow approach with single-point stabilization over the frontozygomatic suture after reduction. Preoperative and postoperative and radiologic images were available. All cases had optimum correction of the clinical deformity. Postoperative stability was excellent in the follow-up period, which had a mean of 18.5 ± 7.81months. There is an increased interest in minimally invasive procedures, and concerns about scarring have increased. Therefore, single-point stabilization over the frontozygomatic suture provides good support to the reduced ZMC with low morbidity.
