Abstract
Apert syndrome is characterized by a wide spectrum of craniofacial clinical features that have been successfully addressed via a variety of midface advancement techniques. Although surgeons have individual preferences as to which specific procedures should be performed to best treat Apert patients, craniofacial plastic surgeons, working in tandem with pediatric neurosurgeons, can identify and evaluate functional limitations and facial morphologic disproportions, and establish appropriate criteria for effective midface advancement technique indication and selection. The purpose of this review article is to present and discuss our rationale for midface advancement technique selection based upon the most common craniofacial characteristics presented by Apert syndrome patients. The present article also provides a grading system that stratifies as major, moderate, and mild, the effect of each midface advancement technique on the different types of Apert syndrome facial features. Surgeons should take into consideration the maximum effect and benefit of each craniofacial osteotomy and how these procedures will alter the craniofacial skeleton. By understanding the long-term effect of each osteotomy on the most common craniofacial characteristics of Apert syndrome patients, craniofacial plastic surgeons and neurosurgeons will be able to customize the surgical procedures they perform in order to achieve the best possible outcomes.

Abstract
Crouzon syndrome is an autosomal dominant trait, leading to midface deficiency, undeveloped orbits, short nasal dorsum, and exophthalmos as the typical clinical features. Early correction of craniofacial problems can improve patients' quality of life, but many of these patients with Crouzon syndrome are seeking treatment in older ages when they are missed for multidisciplinary management and distraction technique in proper timing. Modified LeFort III osteotomy is one of the treatment options that can be used for proper resolution in adult patients. The present case report study aims to describe a patient with midface deficiency due to the Crouzon syndrome who has undergone a combination of modified LeFort III osteotomy with the periocular approach and LeFort I osteotomy, nasal dorsum augmentation accompanied by genioplasty, wholly as a single surgical procedure which has been shown that can result in highly satisfactory outcomes for both patient and surgeon.

Abstract
INTRODUCTION With the increasing possibilities of surgical treatment addressing the complex spectrum of defects in Crouzon syndrome (CS), it is of utmost importance to obtain accurate assessment of the malformation. Evaluating the volume of the posterior fossa is of great importance since many authors, considering that its volume is always decreased, favor posterior fossa enlargement as a first step in the treatment of CS. MATERIAL AND METHODS We studied CT scans of children with CS, which were vestibular-oriented (VO) in order to conform with physiological landmarks, and we measured intracranial volume by manual segmentation; these abnormal CT scans were superposed with VO 3D-CT scanners of age-matched controls. We studied the volume index of the posterior fossa for each CS patient defined as the ratio of its volume in CS patients with the normal for age calculated from normal controls. RESULTS We studied the imaging of 41 children with CS and 70 control. Among CS patients, the volume of the posterior fossa was increased in 10, compared with control. We found closure of the sphenoidal synchondrosis was correlated with age and with the width of the posterior fossa, but not with its length nor with the posterior fossa volume index. CONCLUSION Segmentation on VO-CT scanner and superposition with CT scanners of normal controls is a powerful tool for the study of the impact of CS or other synostoses on volume and shape. We found that CS is more heterogeneous than previously thought, and surgical strategies should be adapted accordingly.

Abstract
OBJECTIVE This retrospective radiographic controlled study investigates the dental phenotype in patients with Crouzon syndrome to determine if differences are observed as suggested by the FGFR2C342Y/+ Crouzon mouse models, and whether these models could be of interest to study the role of this mutation in tooth development. DESIGN We assessed dental phenotype using dedicated linear measurements in 22 children with Crouzon syndrome and compared tooth morphology in both primary and permanent dentitions to an age-matched control group. Descriptive statistics were performed with "Sex" and "Age" as covariates for the permanent tooth models and "Sex" only for the primary tooth models, to take into account potential confounding factors. RESULTS We showed that permanent but not primary tooth dimensions were globally reduced in Crouzon syndrome, without microdontia. In permanent dentition, crown height, mesiodistal and faciolingual cervical diameters were reduced by 6.3%, 5.7% and 5.5% respectively (p < 0.05). CONCLUSION Our results underline the implication of Fibroblast Growth Factor Receptor 2 (FGFR2) in dental development of humans and contribute to support FGFR2C342Y/+ Crouzon mouse models as partial replicas of this condition, including in the oral region.

Abstract
Monobloc and facial bipartition combined with distraction osteogenesis (MFBDO) has gained popularity over the past several years as a treatment of syndromic craniosynostosis, in part because this surgical technique effectively removes many stigmatic clinical features associated with the syndromic face. The objective of this study is to detail the surgical planning used to achieve medialization of the orbits and describe the authors' experience using MFBDO to destigmatize the syndromic face. By using MFBDO, hypertelorism, vertical orbital dystopia, and downslanting of the palpebral fissure were surgically corrected in all patients, thereby destigmatizing the syndromic face.

Abstract
The introduction of distraction osteogenesis to frontofacial monobloc advancement has increased the safety of the procedure. One hundred forty-seven patients with syndromic craniosynostosis underwent frontofacial monobloc advancement using 4 internal distractors. Twenty-five were aged 18 months or less. Ten patients presented with a tracheostomy, 5 (50%) were decannulated after surgery, and 3 others (30%) required an additional intervention before decannulation. Six patients required the addition of a transfacial pin and external traction. Very early frontofacial monobloc with 4 internal distractors is a safe and effective treatment to protect the ophthalmic, neurologic, and respiratory functions in infants with severe syndromic craniosynostosis.

Abstract
The aim of the study was to determine if the additional surgical complexity of Lefort II distraction with zygomatic repositioning (LF2ZR) results in increased complications compared to Lefort III distraction (LF3). A retrospective review was performed of all LF3 and LF2ZR advancements performed by the senior author over 15 years. Demographic, operative, postoperative, and cephalometric data were collected from initial procedure through greater than 1 year postoperatively. Univariate and multivariate analyses were performed to compare procedures. 19 LF2ZR and 39 LF3 in 53 patients met inclusion criteria. Diagnoses differed between procedures, with more Crouzon Syndrome in LF3 and more Apert Syndrome in LF2ZR. Complication rate was 7/19 for LF2ZR and 12/39 for LF3 with no severe morbidity or mortality, and no difference between procedures (p = 0.56). The types of complications encountered differed between procedures. LF2ZR had a significantly longer operative time (506 ± 18 vs. 358 ± 24 min, p<0.001). However, a greater number of LF2ZR patients underwent concomitant procedures (15/19 vs. 13/39, p<0.001). Multivariate analysis revealed that Apert Syndrome and reoperative midface advancement were the most significant predictors of increased blood loss. LF2ZR has an equivalent complication rate to LF3. Therefore, it is our treatment of choice for cases requiring differential sagittal and vertical distraction of the central midface.

Abstract
The severity of obstructive respiratory difficulty varies among affected Crouzon syndrome patients. The aim of this study was to investigate the correlation between the restricted airway volume in Crouzon syndrome and the associated type of cranial vault suture synostosis. Computed tomography scans of 68 unoperated Crouzon syndrome patients and 89 control subjects were subgrouped into four types: type I, bilateral coronal synostosis; type II, sagittal synostosis; type III, pansynostosis; type IV, perpendicular combinations of synostoses. Measurements were made using Mimics software. Of type I Crouzon patients, 42% had a restricted nasal airway (P=0.002), while the pharyngeal airway volume was not significantly reduced. Type II Crouzon patients grew normal segmental airway volumes. Crouzon patients of type III developed simultaneously reduced nasal and pharyngeal airway volumes in infancy, by 38% (P=0.034) and 51% (P=0.014), respectively. However, the nasal airway achieved a normal volume by 2 years of age without any intervention, while the pharyngeal airway remained significantly reduced up to 6 years of age, by 42% (P=0.013), compared to controls. Type IV Crouzon patients developed a reduced nasal airway volume (32%, P=0.048) and a non-significant restricted pharyngeal airway (18%, P=0.325). Airway compromise in Crouzon syndrome is variable when associated with different craniosynostosis fusion patterns. Type II (sagittal synostosis) Crouzon patients grew a normal nasopharyngeal airway volume. Those with types I (bicoronal synostosis) and IV (perpendicular synostoses) had significantly restricted nasal airways and a tendency towards a reduced pharyngeal volume. Type III (pansynostosis) Crouzon infants had the worst restriction of both airways, although there was some improvement with age.

Abstract
Crouzon syndrome is an autosomal dominant disorder characterized by acrocephaly, exophthalmos, hypertelorism, strabismus, parrot-beaked nose, and hypoplastic maxilla. It is usually caused by a pathogenic mutation in the fibroblast growth factor receptor 2 gene and premature fusion of the sutures of the cranium and the base of the skull. This article documents the ophthalmic complications in patients with Crouzon syndrome before and after the influence of craniofacial surgery with particular emphasis on the different mechanisms and treatments involved. It is important to perform timely decompressive surgery before the presence of optic atrophy and corneal defects, and make early detection and adequate management of amblyopia, ptosis and strabismus.

Abstract
INTRODUCTION Fibrous dysplasia is a benign disorder, in which normal bone is replaced by fibrosis and immature bone trabeculae, showing a similar distribution between the genders, and being more prevalent in the earlier decades of life. Fibrous dysplasia of the temporal bone is a rare condition, and there is no consensus as to whether it is more common in monostotic or polyostotic forms. External auditory meatus stenosis and conductive dysacusis are the most common manifestations, with cholesteatoma being a common complication, whereas the involvement of the otic capsule is an unusual one. Surgical treatment is indicated to control pain or dysacusis, otorrhea, cholesteatoma, and deformity. OBJECTIVES To describe the clinical experience of a tertiary referral hospital with cases of fibrous dysplasia of the temporal bone. METHODS Sampling of patients diagnosed with fibrous dysplasia of the temporal bone, confirmed by tomography, treated at the pediatric otology and otorhinolaryngology outpatient clinics, between 2015 and 2018. The assessed variables were age, gender, laterality, external auditory meatus stenosis, deformity, hearing loss, presence of secondary cholesteatoma of the external auditory meatus, lesion extension and management. RESULTS Five patients were included, four females and one male, with age ranging from 13 to 34 years. Three had the polyostotic form and two the monostotic form of fibrous dysplasia of the temporal bone. Four patients had local deformity and external auditory meatus stenosis, two of which progressed to cholesteatoma. All patients showed some degree of hearing impairment. All had preserved otic capsule at the tomography. Two patients are currently undergoing clinical observation; two were submitted to tympanomastoidectomy due to secondary cholesteatoma; one was submitted to lesion resection, aiming to control the dysacusis progression. CONCLUSION Five cases of fibrous dysplasia of the temporal bone were described, a rare disorder of which the otologist should be aware.

Abstract
Crouzon syndrome is the most common syndrome among the craniosynostosis group. Crouzon syndrome accounts for about 4.8% of all of them. It commonly has autosomal dominant inheritance with complete penetrance and variable expressivity from subtle to severe forms and characterized by craniosynostosis, exophthalmos, and hypoplastic maxilla with relative mandibular prognathism. Mutation of the fibroblast growth factor receptor-2 gene is responsible for the occurrence of this rare genetic disorder. Our paper reports the diagnosis of this rare syndrome in a young female patient based on clinical and radiographical features. Prompt and timely management of the syndrome has enabled this patient to lead a normal life despite the syndrome.

Abstract
Crouzon syndrome, also called craniofacial dysostosis, is an autosomal dominant disorder with complete penetrance and variable expressivity. Described by a French neurosurgeon in 1912, it is a rare genetic disorder characterized by premature closure of cranial sutures, midfacial hypoplasia, and orbital defects. Here, we report a case of this rare entity. The patient presented with brachycephaly, maxillary hypoplasia, exophthalmos, mandibular prognathism, along with dental and orbital abnormalities.
