45 Possible Causes for Short Mandibular Ramus

  • Marshall-Smith Syndrome

    Marshall-Smith Syndrome (MRSHSS) is a very rare genetic disorder characterized by failure to thrive and characteristic dysmorphic features associated with accelerated osseous maturation. We present a nine-year-old girl who was diagnosed with MRSHSS based on characteristic clinical features supported by the[…][ncbi.nlm.nih.gov]

  • Trichorhinophalangeal Syndrome

    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] 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]

  • 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] 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]

  • Facial Hemiatrophy

    Parry–Romberg syndrome (also known as progressive hemifacial atrophy ) is a rare disease characterized by progressive shrinkage and degeneration of the tissues beneath the skin , usually on only one side of the face (hemifacial atrophy) but occasionally extending to other parts of the body.

  • Temporomandibular Joint Ankylosis

    However, disadvantages include the following: (1) creation of a pseudoarticulation, (2) a short mandibular ramus with anterior open bite in bilateral cases and posterior open[jkamprs.springeropen.com] The short ramus condyle unit can result in subsequent emergence of unilateral mandibular retrusion, significant malocclusion, and can restrict mid-facial growth [ 14 ].[bmcpediatr.biomedcentral.com] Gap arthroplasty offers an advantage of a simple procedure and requires a short surgical time.[jkamprs.springeropen.com]

  • Saethre-Chotzen Syndrome

    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.medscape.com]

  • Apert Syndrome

    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.medscape.com]

  • Commissural Facial Cleft

    Type one patients have small mandibles with normal shape, a normal glenoid fossa and a short mandibular ramus.[jclpca.org] Type two findings include anteriorly and medially displaced TMJs, a short and abnormally shaped ramus, and an abnormally contoured TMJ cavity.[jclpca.org] Complete absence of the mandibular ramus and glenoid fossa, no TMJ and the body of the mandible ending at the molar region classifies type three patients.[jclpca.org]
