Asymmetric crying facies in an elderly, when a facial asymmetry is not a facial paralysis but a marker of possible congenital malformations: case report and review of the literature.

BACKGROUND: Facial asymmetry when crying at birth (then called asymmetric crying facies or ACF) or when smiling or speaking loudly in adulthood is the consequence of the agenesis or hypoplasia of the muscle of one of the labial commissures. This developmental disorder of complex mechanism is well known by pediatricians to be a warning sign for underlying developmental disorders of variable severity. CASE REPORT: An 80-year-old man with medical history of renal agenesis was hospitalized for a transient motor deficit of the right face and arm revealing a lacunar stroke. Clinical examination showed an isolated left facial asymmetry upon smiling or talking out loud which had been known since childhood and was not related to the stroke, leading to the diagnosis of ACF. Cardiac ultrasound revealed a patent foramen. Chromosomal investigations could not be performed. DISCUSSION AND CONCLUSION: ACF is a rare disorder that may conceal associated congenital disorders such as heart, skeletal, or renal malformations. Its causing mechanisms are to this day still poorly understood but may include a genetic component as shown by familial cases and the identification of 22q11.2 deletions or trisomy 18 in some patients. Knowledge of this disorder seems highly relevant for adult neurologists, first because of the differential diagnosis with facial palsy, but mostly because it will allow them to screen patients for other congenital disorders such as heart malformations. Conversely, cardiologists and cardiac surgeon may search for an ACF when faced with a patient with a congruent heart defect.

Facial hemihypertrophy in a girl with sturge-weber syndrome: Treatment with oral sirolimus.

In the last few years, the use of oral sirolimus has shown promising results in the treatment of some complex vascular anomalies, and recently, it has been used in patients with Sturge-Weber syndrome (SWS). We present the case of an 11-year-old girl with the diagnosis of SWS and hemifacial overgrowth treated with oral sirolimus. Throughout the eight months of follow-up, improvement of the port-wine birthmark, intraocular pressure, and neurocognitive development was noted. The mTOR inhibitors may be useful in the treatment of some patients with SWS.

Hemifacial hyperplasia: a case series and review of the literature.

Condylar hyperplasia is known to result in facial asymmetries and constitutes a well-recognized group of unilateral mandibular enlargements. Condylar hyperplasia has been sub-classified into hemimandibular hyperplasia and hemimandibular elongation. A much rarer disorder, hemifacial hyperplasia (or hemifacial hypertrophy) is a congenital malformation characterized by prominent unilateral overdevelopment of the hard and soft tissues of the face. The affected side grows at a faster rate than the non-affected side, creating a marked asymmetry that potentially involves the skeleton and teeth, as well as all components of the associated soft tissues. Hemifacial hyperplasia is usually identified at birth and progresses towards puberty, but is not thought to alter throughout the lifetime of affected individuals. A case series of five patients clinically diagnosed with hemifacial hyperplasia is presented, with the aim of reviewing the clinical features, discussing their individual surgical management, and summarizing the more recent identification of possible genetic mutations that may be responsible for hemifacial hyperplasia and related overgrowth disorders. It is speculated that depending on the genetic factors, the disorder may be progressive in specific cases.

Unilateral condylar hyperplasia in hemifacial hyperplasia, is there genetic proof of overgrowth?

Hemifacial hyperplasia (HFH) is characterized by an increase in volume of all affected tissues of half of the face. It is present at birth, subsequently grows proportionally, and stops growing before adulthood. Unilateral condylar hyperplasia (UCH) consists of progressive asymmetric growth of the mandible and develops typically in early adulthood. Both disorders have an unknown aetiology. The overgrowth limited to one body part suggests somatic mosaicism, as this has been found in other similar localized overgrowth disorders. Often this includes a variant in a gene in the (PIK3CA)/PI3K/(PTEN)/AKT1/mTOR pathway. Here we report the case of an HFH patient with asymmetry present at birth, in whom a progressive growth pattern similar to UCH subsequently occurred, causing marked mandibular asymmetry. A condylectomy was successfully performed to stop the progressive growth. Somatic mosaicism for a mutation in PIK3CA was detected in the condylar tissue. This finding might indicate that both HFH and UCH can be caused by variants in genes in the (PIK3CA)/PI3K/(PTEN)/AKT1/mTOR pathway, similar to other disorders that result in asymmetrical bodily overgrowth.

Using an expanded scalp flap without fascial flap harvest or skin grafting for total auricular reconstruction in hemifacial microsomia with low hairline.

BACKGROUND: Total auricular reconstruction for hemifacial microsomia patients with extremely low hairline is a tough challenge in plastic surgery. In this work, a brand new technique using a singer expanded scalp flap without skin graft and combined with intense pulse light treatments (IPLT) for ear reconstruction is described in this special population. METHODS: From January 2015 to April 2019, 41 hemifacial macrosomia (HFM) patients with 70-100% low hairline were enrolled in our study. Operative treatment was performed in 3 stages: 1. Expander insertion and inflation; 2. Expander removal, costal cartilage framework fabrication and auricular reconstruction; 3. Tragus reconstruction and reconstructed auricle refinement. Several IPLTs were performed every 45 days until local area become hairless during the whole course. The first IPLT could be executed either before all the operations or during the expansion period. The flap was treated with M22 system using a filter of 695-1200 nm. Follow up ranged from 10 months to 4 years. RESULTS: During follow-up, 90.2% patients were surveyed as satisfied with the outcome, especially in the aspects of minimal scars, natural matched color and clear contour of the reconstructed ear. No serious complications happened. Patients starting the IPLT during the expansion period required less treatment times of depilation (p < 0.05). CONCLUSION: Auricular reconstruction using a single expanded scalp flap combined with intense pulse light depilation is a safe, effective and less invasive technique for hemifacial microsomia with extremely low hairline, and providing highly satisfying results. Initialing the IPLD during the expansion period is recommended. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Craniofacial Bone Fibrous Dysplasia is a benign bone lesion where normal bone tissue is replaced with fibrous tissue. Developed from a genetic mutation. Subordinated in variants: monostotic and polyistotic. Few cases are reported on malignancy of the pathology. The diagnosis is determined with clinical suspicion and confirmed by imaging and pathology tests. CASE REPORT: In this paper, we present a series of three cases diagnosed with Craniofacial Fibrous Dysplasia at José Carrasco Arteaga Hospital and Hospital del Río, Cuenca-Ecuador. All of patients were treated with surgery, because of the clinical features. EVOLUTION: In all the cases, the patient evolution was favorable. Reduction of symptoms and general aesthetic improvement were achieved in all cases. CONCLUSION: Better results are obtained with the current surgical treatments (bone remodeling plus bone freezing), among them: good aesthetic results, better quality of life, lower risk of infections. In the present paper, the three patients treated with the surgical procedure indicated that the treatment reflected positively in the functional, aesthetic and emotional aspects.(au)

Congenital infiltrating lipomatosis of the face: A subtype of hemifacial hyperplasia.

OBJECTIVE: To investigate the clinical, imaging and pathological features of congenital infiltrating lipomatosis of the face (CILF) and to discuss whether it is a subtype of hemifacial hyperplasia (HH). METHODS: Sixteen patients diagnosed with CILF were included in this study. All patients had undergone panoramic radiography and spiral CT examinations. Thirteen patients received biopsy, surgery treatment and pathological examination. The clinical documentation and imaging data were retrospectively reviewed. RESULTS: The cheeks (14/16), parotid glands (12/16), tongues (9/16), masticatory muscles (8/16) and the lips (7/16) were the most frequently affected soft tissue organs. The maxilla (14/16), zygoma (13/16), mandible (13/16) were involved among the maxillofacial bones. Dental malformations included macrodontia (8/16), poor formation of the roots (7/16), accelerated tooth germ development or premature eruption of permanent teeth (7/16) and missing of the permanent teeth (4/16). All malformations were restricted to one side of the face and did not trespass the middle line. Pathologically, CILF was featured by the diffuse infiltration of redundant mature adipose tissue into the tissue of the affected organ. CONCLUSION: CILF is a congenital developmental facial malformation characterized by infiltration of nonencapsulated, mature adipose tissue, resulting in facial soft and hard tissue hypertrophy and dental malformations in hemifacial structures. CILF could be considered as a subtype of HH.

Craniofacial Microsomia.

Clinicians use different diagnostic terms for patients with underdevelopment of facial features arising from the embryonic first and second pharyngeal arches, including first and second branchial arch syndrome, otomandibular dysostosis, oculoauriculovertebral syndrome, and hemifacial microsomia. Craniofacial microsomia has become the preferred term. Although no diagnostic criteria for craniofacial microsomia exist, most patients have a degree of underdevelopment of the mandible, maxilla, ear, orbit, facial soft tissue, and/or facial nerve. These anomalies can affect feeding, compromise the airway, alter facial movement, disrupt hearing, and alter facial appearance.

Postoperative Changes in Orbital Dysmorphology in Patients With Unicoronal Synostosis.

Orbital asymmetry in unicoronal synostosis impacts craniofacial appearance and can potentiate functional visual disturbances, such as strabismus. Surgical treatment aims to normalize overall cranial morphology, including that of the orbits. The purpose of this study was to compare postoperative changes in orbital asymmetry following 2 common procedures.Preoperative and 1-year postoperative computed tomography scans for patients with isolated, nonsyndromic unicoronal synostosis treated from 2007 to 2012, at 2 academic institutions were analyzed. Only patients treated by endoscopic suturectomy and postoperative helmeting or bilateral fronto-orbital advancement were included. Orbital index, depth, and volume asymmetry were determined for each patient both pre- and 1-year postoperatively. Student's t-tests were used to compare pre- and postoperative asymmetries within each treatment group. Regression analyses were used to examine postoperative change in asymmetry between treatment groups.Scans from 12 patients treated by fronto-orbital advancement and 23 treated by endoscopic suturectomy were analyzed. Differences between synostotic and nonsynostotic orbital index, depth, and volume were statistically significant both pre- and postoperatively. Statistically significant postoperative improvements in asymmetry were observed for orbital index, depth, and volume following suturectomy. Regression analysis indicated that the amount of pre- to postoperative change in all measures of asymmetry did not depend on surgical technique. Residual asymmetry following both procedures was apparent at 1 year postoperatively.Orbital asymmetry is improved, but not resolved following both fronto-orbital advancement and endoscopic suturectomy. Degree of improvement in symmetry is independent of surgical technique used.

Is There a Difference in Orbital Volume Between Affected and Unaffected Sides in Patients With Unilateral Craniofacial Microsomia?

PURPOSE: Craniofacial microsomia (CFM) is characterized by malformations of structures derived from the first and second pharyngeal arches. The orbit is variably affected. The purpose of this study was to determine whether there is a difference in orbital volume between affected and unaffected sides in patients with unilateral CFM. The specific aims were to 1) measure orbital volume, 2) compare affected and unaffected sides, 3) evaluate the correlation between clinical evaluation of orbital size and volumetric measurement, and 4) determine whether there is a correlation between orbital volume and severity of mandibular deformity. MATERIALS AND METHODS: This study is a retrospective case series of patients with unilateral CFM from Boston Children's Hospital (Boston, MA) who had a computed tomographic (CT) scan. Manual segmentation of the orbit using Mimics software (Materialise, Leuven, Belgium) was performed on CT images of the 2 orbits. The predictor variable was laterality (affected vs unaffected side) and the primary outcome variable was orbital volume. Wilcoxon signed rank test was used to compare these measurements and determine whether the affected side differed from the unaffected side. The correlation between orbital volume and Pruzansky-Kaban type of mandibular deformity, as documented in the medical record, was determined using the Spearman rank correlation coefficient. RESULTS: Thirty-nine patients were included. Orbital volume was 10% smaller on the affected side (P = .001) in 80% of patients. There was no correlation between orbital size and severity of mandibular involvement. CONCLUSION: The results of this study showed a marked difference in orbital volume between affected and unaffected sides in patients with unilateral CFM. These differences were small and might not be clinically relevant. Orbital volume did not correlate with severity of mandibular deformity.

Principales aspectos neurofisiológicos, clínicos, y genéticos, en una recién nacida con Síndrome de Cayler / Clinical, genetic, and neurophysiological main features in a newborn girl with Cayler Syndrome

En los neonatos, la hipoplasia o agenesia congénita del músculo depresor del ángulo de la boca (depresor anguli oris), es la causa de la asimetría facial durante el llanto. Los pacientes con esta anomalía, presentan caída de la comisura labial del lado intacto a diferencia de la parálisis facial de origen traumático o congénito, y su diagnóstico se obtiene fácilmente, mediante el examen físico. Esta anomalía está asociada con otras de origen congénito, sobre todo los defectos cardíacos, por lo que se nombra síndrome cardiofacial de Cayler. Se presenta una niña, recién nacida de 56 horas, atendida en el servicio de Neonatología del Hospital Pediátrico “Octavio de la Concepción de la Pedraja” de Holguín, Cuba. La paciente egresa con diagnóstico de síndrome de Cayler, al presentar asimetría facial durante el llanto, y tetralogía de Fallot. Se realizan estudios neurofisiológicos como: electroneurografía del nervio facial y electromiograma de los músculos depresores del labio.(AU)

Asymmetrical Crying Facies Syndrome, is caused by congenital hypolapsia or anguli oris agenesis. Patients usually present drop of the intact corner of their mouths while crying. Though it is easily diagnosed, it must be differentiated from traumatic or congenital facial palsies. This condition has been associated with several other anomalies, especially with heart issues. That´s why it is called Cayler Cardiofacial Syndrome. We have reported a case of a 56 hours newborn girl. She shows facial asymmetry as a valuable sign for suspecting other congenital anomalies. Clinical evaluation, including facial nerve electroneurography and electromyography, were performed.(AU)

Lower face asymmetry as a marker for developmental instability.

OBJECTIVES: Fluctuating asymmetries in the craniofacial skeleton have been shown to be predictive for mortality from degenerative diseases. We investigate whether lower face asymmetries are a potential marker for the developmental origins of health and disease. METHODS: The lower face of a representative sample of 6654 12- to 17-year old United States (US) adolescents (1966-1970, National Health Examination Survey III) was classified as asymmetric when the mandibular teeth occluded prognathically (forward) or retrognathically (backward) on one side of the face only. It was investigated whether these lower face asymmetries were directional (preferentially to the left or the right) or fluctuating (random left-right distribution) in the US population. RESULTS: Lower face asymmetries affected 1 in 4 of the US adolescents. Unilateral retrognathic dental occlusions were fluctuating asymmetries, had a US prevalence of 17.0% (95% confidence interval: 15.5-18.4) and were associated with race/ethnicity (P < .0001), not with handedness (P < .7607). Unilateral prognathic dental occlusions were directional asymmetries (P < .0001), had a US prevalence of 7.6% (95% confidence interval: 6.4-8.7) and were associated with large household size (P < .001) and handedness (P < .0223). Lower face asymmetries were not associated with distinct heritable traits such as color blindness. CONCLUSIONS: The findings suggest that lower face asymmetries are a marker for environmental stress and cerebral lateralization during early development.
