DEVELOPMENTAL ANOMALIES CLINICAL FEATURES HISTOPATHOLOGY; Fissured tongue: Fissured Tongue (FT) is a relatively common condition. It is also considered to be a variant of the normal tongue. FT is known to occur more frequently in adults. It is characterized by the presence of numerous grooves or fissures on the dorsal and lateral surface of the. A host of things can go wrong with the formation of the tongue, since it develops from multiple sources, rather than a single progenitor process. Most of the developmental disturbances of the.. ANKYLOGLOSSIA It can be defined as a developmental condition characterized by fixation of tongue to the floor of the mouth, causing restricted movement It can be either complete ankyloglossia or partial ankyloglossia (tongue tie) Complete ankyloglossia occurs as a result of fusion between the tongue and the floor of the mouth Partial ankyloglossia occurs as a result of short lingual frenum or due to a frenum which attaches too near to the tip of the tongue PDF | On Jan 1, 2004, Sivapatha Sundharam and others published Study on the developmental anomalies of the tongue | Find, read and cite all the research you need on ResearchGat Developmental anomaly Characterized by short, thick lingual frenum Complete - fusion between tongue and floor of the mouth Partial - tongue tie - short lingual frenum attached to the tip of the tongue
Although easily examined, abnormalities of the tongue can present a diagnostic and therapeutic dilemma for physicians. Recognition and diagnosis require a thorough history, including onset and. Ankyloglossia is a usually minor developmental anomaly of the tongue resulting from a congenital short, thick lingual frenulum (Fig. 9.9). In the most severe variant the tongue may be fused with the floor of the mouth. Mild ankyloglossia occurs in 2-4% of newborns but is severe enough to require consultation in only 2-3/10 000 individuals Congenital malformations of the oral cavity include cleft lip, palate, and alveolus defects, developmental anomalies of the tongue, vascular anomalies, developmental disturbances of the teeth and/or tooth structure, and congenital dysontogenetic tumors or tumorlike conditions with differential growth of the embryo, the diverticulum elongates, but remains connected to the forming tongue by a thyroglossal duct that later is obliterated; the site of the opening of the thyroglossal duct is the foramen cecum found in the midline at the terminal sulcus of the tongue. Anomalies in thyroid development can result in ectopic.

Fact 5: It is a congenital anomaly. Regardless of whether tongue-tie is genetic or epi-genetic, it occurs during development in the embryonic period. Fact 6: Because tongue-tie, by definition, is impaired tongue mobility due to a congenital anomaly, it can cause deficits in all functions that require optimal tongue mobility, whether that be. Causes of congenital anomalies. It has been estimated that about one quarter of all congenital anomalies might have a genetic cause ().However, more recent estimates suggest the proportion could be higher, as advances in cytogenetic and molecular techniques in the last two decades are allowing the identification of previously undetected chromosomal abnormalities, gene mutations and genetic. A sequence is a group of related anomalies that generally stem from a single initial major anomaly that alters the development of other surrounding or related tissues or structures. Potter's sequence is recognized by a constellation of physical findings where the outward appearance of the newborn is often characterized by flattened abnormal. Advances in genetics and molecular biology have led to a better understanding of the control of central nervous system (CNS) development. It is possible to classify CNS abnormalities according to the developmental stages at which they occur, as is shown below. The careful assessment of patients with these abnormalities is important in order to provide an accurate prognosis and genetic counselling
Ankyloglossia, also known as tongue-tie or TOTs, is a congenital oral anomaly that may inhibit the mobility and proper function of the tongue. The primary function of frenums is to keep the lips and tongue in harmony with the growing bones of the mouth during development. The frenums of most concern are those found under the tongue, front upper lip, and front lower lip Nowak K, Szyfter W.

Atrophic tongue associated with candida developmental anomaly characterized by a shortened lingual frenum that limits movement of the tongue. Can cause speech problems, periodontal defects, and problems with breast feeding. More common in male
Ankyloglossia (tongue-tie) Ankyloglossia is a congenital developmental anomaly of the tongue characterized by a short, thick lingual frenulum result- ing in limitation of tongue movement (partial ankyloglossia) or by the tongue appearing to be fused to the floor of the mouth (total ankyloglossia). Studies with different diagnosti Notable glandular parenchyma anomalies are the SG aplasia and the ectopic SG tissue. Major SG aplasia is a developmental anomaly, leading to variable degrees of xerostomia, and oral dryness. Ectopic SG tissue can occur as accessory gland tissue, salivary tissue associated with branchial cleft anomalies, or true heterotopic SG tissue
The developmental oral anomalies identified in this study were: torus palatinus (1.4%), fissured tongue (0.8%), geographic tongue (0.2%), and tongue tie (0.1%). None of the following developmental oral anomalies were observed: lip pits, cleft lip and/ or palate, torus mandibularis, microglossia, macroglossia or median rhomboid glossitis Coated tongue : White, brown, black, yellow discoloration of the dorsal tongue without prominent elongation of the filiform papillae. Oral hairy leukoplakia : Only included in differential diagnosis due to similarity of terminology. Most often presents as furrowed white plaques on lateral tongue. Associated with Epstein-Barr virus The lingual thyroid gland is the thyroid tissue seen in the base of the tongue caused due to the embryonic developmental anomaly of the thyroid gland tissue. Treatment of Anomalies The treatment for cyst is excision and the normal recovery occurs There are few anomalies that can affect the lingual frenulum and sometimes interfere with function, such as ankyloglossia, where the frenulum is attached near the tip of the tongue, commonly described as tongue tie, or absence of the lingual frenulum either sporadically or in some developmental conditions, such as Ehlers-Danlos syndrome.
The observed developmental anomalies are classified into: cysts, cysts with sinuses developing as a result of inflammatory processes, puncture, incision, operation, dermal sinuses draining externally, dermal sinuses with external and internal orifices, the latter in the groove of the palatine tonsil or foramen caecum of the tongue, dermal sinus. Tongue Anomalies: Ankyloglossia or microglossia refers to incomplete or abnormal development of the tongue. It is often referred to as bird tongue in dogs and may be a component of the fading puppy syndrome. Affected puppies have difficulty nursing and do poorly. Oral examination reveals missing or underdeveloped lateral and rostral thin.
Double tongue results due to developmental anomaly within a lingual tubercle.5 We report a patient with an accessory tongue which was excised successfully. Case report: A 48 year old middle aged man presented to our OPD for throat pain and mild discomfort while swallowing since 15 days. On examination of th Purpose of Review Developmental anomalies affecting orofacial region are not that uncommon. Genetic factors play an important role in developmental anomalies of the orofacial region. However, the role of other factors including nutrition cannot be disregarded. This review focuses on the current literature regarding the role of nutrition in the normal development and various developmental. The human tongue is a muscular organ attached by multiple ligaments to the mandible, hyoid bone, styloid process, and pharynx .It originates from the first, second, and third pharyngeal arches and develops at the beginning of the fourth intra-uterine week .During this phase, a U-shaped sulcus develops in front of and on both sides of the oral part of the tongue which gives the tongue its. Rarely (in less than 1% of cases), cancer may be present in a thyroglossal duct cyst. These tumors are generally papillary thyroid carcinomas, arising from the ectopic thyroid tissue within the cyst.. Causes. Thyroglossal Duct Cysts are a birth defect.During embryonic development, the thyroid gland is being formed, beginning at the base of the tongue and moving towards the neck canal, known as.
A quick reference diagnostic guide for students and clinicians, covering a wide range of oral and dental developmental anomalies in children and adolescents Written by world-renowned pediatric dentists, this easily accessible, well-illustrated reference covers a wide range of oral and dental developmental anomalies in children and adolescents, and includes rare as well as more common conditions Treatment of natal teeth may involve observation, smoothing of the incisal edge (to prevent potential discomfort during breastfeeding and ulceration of the ventral tongue or the floor of the mouth [Riga-Fede disease]), or extraction . Extraction of natal teeth should be considered only if they cause feeding difficulties for the infant or mother This depends on the presence of associated anomalies. Severe micrognathia can be a neonatal emergency due to airway obstruction by the tongue in the small oral cavity. If prenatal diagnosis is made a pediatrician should be present in the delivery room and be prepared to intubate the infant. Otocephaly is lethal
Developmental anomalies in the primary dentition If there is no abnormality in the shape of a complete cleft, the primary dentition will develop normally. Malposition of teeth is relatively rare and only slightly pronounced. Typical anomalies in the immediate area of the mouth include the following # A union of the roots of adjacent teeth through the cementum is referred to as : A. Concrescence B. Fusion C. Gemination D. None of the above # The term dilaceration refers to : A. A deformity of a tooth consisting of a sharp bend in the root B. Abrasions on two surfaces of a single tooth C.

Developmental disturbances of tongue 5.1. aglossi Development of the Palate. Initially, the nasal cavity is continuous with the oral cavity. A series of steps lead to their separation, and the establishment of the palate.. As the nose forms, the fusion of the medial nasal prominence with its contralateral counterpart creates the intermaxillary segment - which forms the primary palate (becomes the anterior 1/3 of the definitive palate) Tongue-tie (ankyloglossia) is a condition present at birth that restricts the tongue's range of motion. With tongue-tie, an unusually short, thick or tight band of tissue (lingual frenulum) tethers the bottom of the tongue's tip to the floor of the mouth, so it may interfere with breast-feeding
Excess retinoic acid (RA) during pregnancy can cause various developmental anomalies in both humans and rodents. We investigated the mechanisms underlying the aberrant differentiation of tongue muscles in fetal mice exposed to exogenous RA in utero.RA-degrading enzymes (Cyp26a1 and Cyp26b1) were expressed at early stages of normal tongue development, but exogenous RA perturbed their expression. A developmental anomaly is a broad term for conditions which are present at conception or occur before the end of pregnancy. In the case of cerebral palsy, a small number also occur after birth. An anomaly is considered a change from normal development and can affect: structure - how the body is built. function - how the body works tickling of the tongue. 12 Some authors propose BHT, HT and FT as causes of burning mouth syndrome.13,14 Ankyloglossia is defined as a minor developmental anomaly of the tongue resulting from a congenital short, thick lingual frenulum, ranging from severe, in which the tongue may be fused with the floor of the mouth to a mil
We hypothesized that thyroid developmental anomalies (TDA) might also be present in families of patients with CH due to thyroid dysgenesis. As shown in Fig. 2, they were seen in a suprahyoid location at the base of the tongue in 11 cases. In three cases, the cyst was located at a position inferior to the hyoid between the hyoid bone and the. Describe normal tongue and jaw range of motion.

Among various sites of involvement 60% cases are located in the head and neck, rarely in the oral cavity where lips, tongue, buccal mucosa, and palate most commonly involved. It is Macroglossia is the abnormal enlargement of the tongue in proportion to other structures in the mouth. It usually occurs secondary to an underlying disorder that may be present from birth (congenital) or acquired.In rare cases, it is an isolated, congenital feature. Symptoms associated with macroglossia may include drooling; speech impairment; difficulty eating; stridor; snoring; airway.
Orofacial muscular/structural differences that encourage tongue fronting could include: delayed neuromotor development, premature exfoliation of maxillary incisors that encourage fronting of the tongue, orofacial anomalies, and ankyloglossia . By unknown mechanism, the normal fetal apoptosis of the cranial ⅔ of the frenulum does not occur. Congenital and Developmental Anomalies. Further posterior to the copula, an epiglottic swelling arises cranial to the laryngeotracheal groove (see Development of the Respiratory System chapter). Tongue muscles develop primarily from myoblasts derived from occipital somites that migrate into the lower jaw and are innervated by the hypoglossal nerve (CN XII) Introduction. Fissured tongue is a commonly encountered tongue disorder in dental practice. But there is a lack of data on different pattern, severity, and association of fissuring with various systemic disorders and other tongue anomalies. This study attempts to establish a classification system for fissured tongue and to know the correlation with the systemic health and other disorders of. Congenital Anomalies and Malformation Syndromes Joseph R. Siebert, Ph.D. The study of congenital anomalies continues to be hampered by misunderstandings at a number of levels.

Statement of Problem: Developmental anomalies of the tongue frequently occur in patients with other congenital or developmental defects.Purpose: The aim of this study was to assess the prevalence of developmental anomalies of the tongue among handicapped students of Yazd city.Materials and Method: In this cross-sectional study, 400 handicapped children were randomly selected among the special. environmental and biological factors.The developmental anomalies included in this study is in region of dentition, tongue, salivary gland, lip, palate and mucosa. Disturbances and alteration in the different stage of tooth development lead to the development of dental anomalies Thyroid Gland. The thyroid gland begins development as a proliferation of endodermal cells between the cupola and tuberculum impar of the primitive tongue (the site of the future foramen cecum).. This proliferation of cells bifurcates and descends into the neck as a two-lobed diverticulum.By week 7, it has reached its destination in the anterior neck, and is formed of two lateral lobes.
, among them the prevalence of coated tongue was 265 (55%), Conclusions: Parents of children with developmental anomalies should be educated about the type and cause of anomaly and they should even be motivated to get the possible treatment done for the same Minor Physical Anomalies (MPAs) are subtle abnormalities of the head, face, and limbs, without significant cosmetic or functional impact to the individual. They are assumed to represent external markers of developmental deviations during foetal life.

Images show a tongue shaped developmental anomaly of right lobe of thyroid gland with contralateral Graves disease (left lobe) Pyramidal lobe. It is an additional lobe of thyroid gland, in fact remnant of the thyroglossal duct which appears like a long pyramid or a conical shaped structure The site of this development lies between 2 key structures, the tuberculum impar and the copula, and is known as the foramen cecum. The thyroid initially arises caudal to the tuberculum impar, which is also known as the median tongue bud Tongue Muscles in Fetal Mice Junko Okano,1 Yasuo Sakai,2 and Kohei Shiota1,3 Excess retinoic acid (RA) during pregnancy can cause various developmental anomalies in both humans and rodents. We investigated the mechanisms underlying the aberrant differentiation of tongue muscles in fetal mice exposed to exogenous RA in utero De Jussieu was the first to describe microglossia in 1718. 1 He reported on a 15-year-old with what he termed congenital lingual hypoplasia. In 1932 the literature up to that date was reviewed by Rosenthal, 2 and he also documented the first report of the hypoglossia-hypodactilia syndrome. Subsequent reports have been released confirming a relationship between hypoglossia and.
