20 Possible Causes for Short Mandibular Ramus

  • Marshall-Smith Syndrome

    Abstract Radiographic, clinical, and histologic findings in two infants and a neonate with a syndrome of profoundly accelerated skeletal maturation included features closely resembling those of Marshall-Smith (MS) syndrome, but patients had dysmorphic ears as well as distinctive generalized skeletal abnormalities[…][radiology.rsnajnls.org]

  • Cardiodysrhythmic Potassium-Sensitive Periodic Paralysis

    Due to its varied and variable phenotypes, Andersen‐Tawil syndrome (ATS) holds a unique place in the field of channelopathies. Patients with ATS typically present with the triad of periodic paralysis, cardiac arrhythmias, and developmental dysmorphisms. Although penetrance of ATS is high, disease expression and[…][doi.org]

  • Facial Hemiatrophy

    We describe a woman with right hemifacial atrophy, a high palate, partial left motor seizures, and mild atrophy of the left arm. CT scan showed asymmetrical lateral ventricles and MRI (magnetic resonance imaging) showed atrophy of the right cerebral hemisphere and agenesis of the head of the right caudate nucleus.[…][ncbi.nlm.nih.gov]

  • Trichorhinophalangeal Syndrome

    The affected group had a shortened posterior face height (p less than 0.01) associated with a short mandibular ramus (p less than 0.01) as well as a reduced and superiorly[ncbi.nlm.nih.gov] The typical craniofacial features include thin upper lip, elongated philtrum, large outstanding ears, shortened posterior facial height associated with short mandibular ramus[ncbi.nlm.nih.gov]

  • Congenital Mandibular Hypoplasia

    In the presented case, the patient happened to have a severe mandibular hypoplasia because of short ramus and mandibular body. What Is Mandibular Hypoplasia?[mandibulartori.com] There was hypoplastic condyle with short ramus on right side resulting in mandibular deviation towards right side and occlusal cant.[omicsonline.org] This could be a little story about a condition called mandibular hypoplasia.[mandibulartori.com]

  • Syndromic Orbital Border Hypoplasia

    In the presented case, the patient happened to have a severe mandibular hypoplasia because of short ramus and mandibular body. What Is Mandibular Hypoplasia?[mandibulartori.com] This could be a little story about a condition called mandibular hypoplasia.[mandibulartori.com]

  • Progeria

    Oral Maxillary, Zygomatic Arch, and Parotid Gland Features A short mandibular ramus was seen in 15/18 (83%) patients, with a gracile thin zygomatic arch in 6/12 (50%) ( Fig[ajnr.org] mandibular ramus in 83% of the patients, with a gracile thin zygomatic arch in 50% of them.[ncbi.nlm.nih.gov] Lateral projection of a 3D CT shaded-surface display reveals a short mandibular ramus, a steep mandibular angle with disorganized dentition ( A ), and a thin gracile zygomatic[ajnr.org]

  • Hypodontia

    The mandibular ramus was short in length and the mandibular condyle had not developed on the right.[ncbi.nlm.nih.gov] Radiographic examination disclosed that the maxillary and mandibular right and left second premolars were not developing.[ncbi.nlm.nih.gov]

  • XXXXY Syndrome

    Cephalometric findings showed a short ramus of the mandible and a short maxilla in the anterioposterior plane. The anteroposterior jaw relationship was in harmony.[ncbi.nlm.nih.gov] The maxillary and mandibular primary central incisors were in a cross-bite relationship.[ncbi.nlm.nih.gov]

  • Mandibulofacial Dysostosis

    The components of the syndrome are low-set ears, short mandibular ramus, micrognathia, chin deviation, occlusal cant, and anterior open bite. See the images below.[emedicine.com]
