Anomalies of Tooth Morphology. Developmental abnormalities in crown and/or root morphology or shape are collectively relatively common and are diverse in both their clinical presentation and apparent etiology.
These developmental variances can involve one or more teeth and can affect any portion or component of the tooth (e.g., crown, root, pulp).Author: J.

DISCUSSION. Absence of the septum pellucidum is a congenital defect in the development of the midline telencephalic structures, although it can rarely be an acquired phenomenon, as seen in cases of prolonged, severe hydrocephalus or head trauma ().Barkovich and Norman reviewed the magnetic resonance images of 35 brains that lacked the septum pellucidum and reported the presence of one.
Semicircular canal dysplasia is relatively common of the labyrinthine anomalies. About 40% of patients with a malformed cochlea will have associated lateral semicircular canal (SCC) dysplasia other two common labyrinthine anomalies include SCC aplasia and SCC dehiscence.

Microdontia can be associated with hypodontia, as in the example of X-linked hypohidrotic ectodermal dysplasia where a heterozygous female might have one missing lateral incisor and a peg-shaped crown of the contralateral maxillary lateral incisor. Figure Supplemental tooth Genetic disturbances or environmental factors during tooth morphogenesis may lead to odontogenic anomalies.
Combination of multiple dental anomalies is usually associated with specific syndromes. Cases with non-syndromic occurrence of multiple dental anomalies have been reported in the literature [1,2]. Syndactyly of feet also known as webbed.
Developmental anomalies of the nose encompass a diverse group of conditions. In this article, embryologic development of the nose and nasal cavities are discussed, as well as anomalies of the nose to include nasal dermoids (eg, gliomas, encephaloceles, nasal clefts, proboscis lateralis, arhinia, polyrrhinia, nasopharyngeal teratoma, epignathus).

Unilateral Tessier no. 5 cleft (after T essier). Microdontia (small teeth) can be isolated or associated with genetic syndromes. The most commonly affected teeth are the maxillary permanent lateral incisors. They may be of normal shape or peg-shaped.
One of the most common causes of microdontia appears to be mutations of the MSX1 gene. Such mutations can also lead to hypodontia and orofacial clefting. Diencephalic-mesencephalic junction (DMJ) dysplasia is a rare malformation characterized by a poorly defined junction between the diencephalon and the mesencephalon and associated with a characteristic butterfly-shaped contour of the midbrain on axial sections on MR imaging.

Anne Dieux-Coeslier's 54 research works with citations and 4, reads, including: A second cohort of CHD3 patients expands the molecular mechanisms known to cause Snijders Blok-Campeau syndrome.
The fetal skeleton is usually evaluated as part of a routine ultrasound around week 20 of the pregnancy. If a skeletal dysplasia is suspected, the expectant mother will likely be referred to a facility that specializes in diagnosing, treating and caring for babies with congenital anomalies, such as the Center for Fetal Diagnosis and Treatment at The Children’s Hospital of Philadelphia.

A developmental concavity of the lingual cortex of the mandible, usually in the third molar area, caused by overextension of an accessory lateral lobe of the submandibular gland, and has the radiographic appearance of a well-circumscribed cystic lesion within the bone, usually below the inferior alveolar canal.
Hip Dysplasia (Developmental Dysplasia of the Hip-DDH, Congential Dysplasia of the Hip-CDH) The normal hip (see figure) is a ball and socket joint with the femoral head (ball) well-seated and stable within the acetabulum (socket).
Hip dysplasia includes a group of disorders that have deformities of the joint. Malignant tumors of the central nervous system associated with familial polyposis of the colon - See Microphthalmia with brain and digit developmental anomalies - See Microphthalmia dwarfism, chondrodystrophy, ocular and facial anomalies - See Schwartz Jampel syndrome; Myotonic myopathy, proximal - See Myotonic dystrophy type.
Embryology of the temporomandibular joint. In contrast to other diarthrodial joints, during prenatal life the TMJ lags morphologically behind other synovial joints in both the timing of its appearance and its progress, so that at birth the joint is still largely underdeveloped (Cleall ; Buchbinder & Kaplan ).TMJ is the last joint to start development, beginning at about the 7th week in.
Differential diagnoses included cortical dysplasia, vascular malformation and oligodendroglioma. Angiography revealed a normal arterial phase, but enlarged medullary and cortical venous channels were noted draining into the superior sagittal sinus (Fig.
2), which suggested the diagnosis of cortical dysplasia with developmental venous anomaly. This sequence is known to be associated with noncontiguous anomalies, such as CNS defect and radial dysplasia, which do not lie in the same field.
The pathogenesis of sirenomelia is uncertain. Some of the proposed theories include posterior axial mesodermal defect [ 68 ] [ 69 ], vascular steal [ 70 ] [ 71 ], teratogenic effect [ 72 ], axial.
Frontonasal dysplasia, also known as median cleft face syndrome, is a rare craniofacial disorder characterized by widely spaced eyes, a broad nose, a vertical groove down the tip of the nose, a nose that may be split in two, and/or an abnormal, covered gap in the skull (cranium bifidum occultum).
DEVELOPMENTAL ANOMALIES of SOFT TISSUES - authorSTREAM Presentation. Slide Other rare facial clefts like lateral facial cleft occurs as a result of failure of fusion of maxillary and mandibular processes leading to a cleft from corner of mouth toward ear.

Frontonasal dysplasia (FND) is a congenital malformation of the midface. For the diagnosis of FND, a patient should present at least two of the following characteristics: hypertelorism (an increased distance between the eyes), a wide nasal root, vertical midline cleft of the nose and/or upper lip, cleft of the wings of the nose, malformed nasal tip, encephalocele (an opening of the skull with.
Congenital dysplasia of the hip (CDH) is an abnormality of the seating of the femoral head in the acetabulum. Its severity ranges from mild instability of the femoral head with slight capsular laxity, through moderate lateral displacement of the femoral head, without loss of contact of the head with the acetabulum, up to complete dislocation of the femoral head from the acetabulum.

Prevalence: Approximately 70 cases have been described in children, including two. Summary: InMichel described a condition characterized by a total absence of differentiated inner ear structures associated with other skull base anomalies, including an abnormal course of the facial nerve and jugular veins.
Michel aplasia clearly differs from Michel dysplasia, in which arrest of embryologic development occurs later. Acromelic frontonasal dysplasia (AFND) is a very rare clinically distinct condition exhibiting severe craniofacial anomalies including hypertelorism, median cleft face, bifid nasal tip, widely spaced nasal alae, parietal defects, and limb anomalies including polydactyly, tibial hypoplasia, and talipes equinovarus.
Hemifacial microsomia (HFM) is a congenital disorder that affects the development of the lower half of the face, most commonly the ears, the mouth and the usually occurs on one side of the face, but both sides are sometimes affected.
If severe, it may result in difficulties in breathing due to obstruction of the trachea—sometimes even requiring a tracheotomy. Dysplasia is a term which means something did not develop the way it should have.
For a condition to be called ectodermal dysplasia at least two parts of the body derived from the embryonic ectoderm need to have not developed in the normal way. There are over types of ectodermal dysplasia. Among the disorders with proven type II collagen defects, the following are associated with anomalies of the odontoid, ranging from mild hypoplasia to aplasia,with or without C subluxation: hypochon-drogenesis, spondyloepiphyseal dysplasia congenita, Kniest dysplasia, and spondylo-epi-metaphyseal dysplasia (Strudwick type) (Lachman ).

Signs and symptoms of cleidocranial dysplasia can vary widely in severity, even within the same family. Individuals with cleidocranial dysplasia usually have underdeveloped or absent collarbones, also called clavicles ("cleido-" in the condition name refers to these bones).
