UNLABELLED Obstructive sleep apnea syndrome is a complex disease, which the etiology is multifactorial and incompletely understood. Surgery with genioglossus advancement is indicated in hypopharynx obstruction. AIM evaluate the efficacy and complications of genioplasty technique for genioglossus muscle advancement in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS p...

RATIONALE Coffin-Lowry syndrome (CLS) is a rare inherited disease with specific clinical features, such as mental retardation, facial dysmorphism, and cardiac abnormality. In particular, the characteristic facial features of CLS, including retrognathia and large tongue, are associated with difficult ventilation and/or intubation, which is a serious problem of anesthesia management. However, cas...

T reacher-Collins syndrome (TCS) or mandibular dysostosis, is a rare autosomal dominant craniofacial malformation that has been described extensively in the scientific literature, 1 with more than 250 cases reported. 2 Most reports to date have focused on the facial morphology of this syndrome: antimongoloid slanting of palpebral fissures, malformed auricles, mandibular and zygomatic bone hypop...

OBJECTIVE To define parameters that enable the objective diagnosis of anomalies of the position and/or size of the fetal mandible in utero. DESIGN Fetuses at 18-28 gestational weeks were examined by two- and three-dimensional ultrasound. The study included normal fetuses and fetuses with syndromes associated with known mandible pathology: Pierre Robin sequence or complex (n = 8); hemifacial m...

In reviewing the literature relative to the development of Class II malocclusions, it can be learned that "not every Class II is a Class II." We must remember that behind the soft tissue drape of the patient’s face is a totally dynamic process that can be influenced by our heritage and altered by our environment. We realize when performing an occlusal evaluation of our young patients, findings ...

Treacher Collin’s syndrome (TCS) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. Patients with TCS present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. Because of retrognathia, airway manageme...

Treacher Collins syndrome (TCS) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. The mechanism of inheritance is autosomal dominant with variable expressivity. Because of this variability in expression, some affected individuals exhibit virtually no overt clinical manifestations. However, most childr...

Temporomandibular joint ankylosis, a debilitating disease mainly affecting children, is characterized by progressive restriction of mouth opening and maxilla-mandibular developmental deformities. Craniofacial distraction osteogenesis has been developed as a standard surgical strategy for rectification of craniofacial deformities. The purpose of this study was to assess mono-planar distraction d...

A 4-week-old male infant presented with hypothermia, hypoglycemia, and hyperbilirubinemia. His medical history was remarkable for hydrocephalus secondary to an arachnoid cyst, intermittent hypoglycemia, hypothermia, and poor feeding requiring nasogastric tube for nutrition. Physical exam revealed retrognathia, mild hypotonia, micropenis, and clinodactyly. Ophthalmologic exam demonstrated bilate...

Mutations in the genes encoding fibrillin, an extracellular matrix protein involved in providing elastic properties to the connective tissues, may result in specific craniofacial and oral anomalies. A number of craniofacial (retrognathia, dolichocephaly, high palate) and dental (root deformity, pulp calcification) manifestations are considered pathognomic for the Marfan syndrome (MFS), a condit...
