57 Possible Causes for Facial Muscle Atrophy, Percussion Myotonia

  • Oculo-Pharyngo-Distal Myopathy

    myotonia: delayed relaxation following percussion of the thenar eminence Grip myotonia: delayed relaxation of firm handshake Reflexes depressed Gait: high steppage (foot[evidencereviewed.com] Weakness in masseter, facial, and bulbar muscles have been observed but no muscle group seems to be spared. Atrophy of facial muscles is common and may be pronounced.[disorders.eyes.arizona.edu] Affected patients have a typical “hatchet-faced” appearance due to temporalis, masseter, and facial muscle atrophy and weakness.[clinicalgate.com]

  • Paramyotonia Congenita

    They experience neither grip nor percussion myotonia during warm weather, whereas myotonia is provoked by cold. Her younger son has no symptoms.[ncbi.nlm.nih.gov] DM1: Characteristic facial appearance with frontal balding, atrophy in the temporal muscles, ptosis and tented upper lip. Distal muscles are more affected.[now.aapmr.org] Also of diagnostic importance are the myotonic reactions inducible at room temperature, such as percussion myotonia, active myotonia and paradoxical myotonia.[ncbi.nlm.nih.gov]

  • Generalized Myotonia of Thomsen

    On examination he showed percussion myotonia. There was no grip myotonia or eyelid myotonia. Nerve conduction studies were normal.[jnnp.bmj.com] The following features are however constantly present: atrophy of the intrinsic hand muscles, facial muscle involvement, myotonia and dystrophic changes in nonmuscular tissue[neuroweb.us] Secondary outcomes: (1) clinical relaxation time; (2) electromyographic relaxation time; (3) stair test; (4) presence of percussion myotonia; and (5) adverse events.[cochrane.org]

  • Myotonic Dystrophy

    Percussion myotonia or myotonia of grasp or both is usually present if looked for.[pediatrics.aappublications.org] From a clinical point of view, the patient displayed a pattern of muscle involvement reminiscent of both disorders, including hand-grip myotonia, facial, axial and distal[ncbi.nlm.nih.gov] In the clinical neurological examination, there was a facial but no limb muscle weakness or atrophy. Ankle jerks were weak.[bmcresnotes.biomedcentral.com]

  • Muscular Dystrophy

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] Facial muscle atrophy and weakness leads to drooping of the lower lip, which has unfavorable functional and aesthetic outcomes.[ncbi.nlm.nih.gov] […] typically elicited by percussion of the thenar eminence with a tendon hammer—‘percussion myotonia’.[doi.org]

  • Sarcotubular Myopathy

    There was no actionor percussion myotonia, or muscle rippling. The tendonreflexes and sensory examination were normal.[documents.tips] There is proximal muscle weakness (pelvic and/or shoulder girdle) with atrophy and sparing of facial and neck muscles.[annalsofian.org] There is often asymmetric quadriceps, hamstring, biceps, brachioradialis, or calf weakness and atrophy. Muscle pain is common.[emedicine.medscape.com]

  • Limb-Girdle Muscular Dystrophy Type 1E

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] ; normal or weak facial muscles; cramps Cardiomyopathy LGMD2H (Manitoba Hutterite Dystrophy) TRIM32 / tripartite motif containing protein-32 Adulthood High Slow Variable LGMD2I[now.aapmr.org] There is proximal muscle weakness (pelvic and/or shoulder girdle) with atrophy and sparing of facial and neck muscles.[annalsofian.org]

  • Myotonic Syndrome

    […] used to test for percussion myotonia.[now.aapmr.org] Myokymia, muscle hypertrophy and percussion "myotonia" in chronic recurrent polyneuropathy. Neurology. 1978 Nov. 28(11):1130-4. [Medline].[emedicine.medscape.com] […] and stretch- or percussion-induced episodic rolling movement of muscle 2[jaoa.org]

  • Upper Limb Hypertrophy

    No percussion myotonia or involuntary movements were noted. Sensory examination was normal and tendon reflexes were elicited normally and symmetric.[amhsjournal.org] […] of the Upper Limbs and Facial Muscles: Case Report and Literature Review.[omicsonline.org] 2013; Published Date: April 30, 2013 Citation: Hannawi S, Salmi IA (2013) Klippel Trenaunay Syndrome, Inverse Klippel Trenaunay Syndrome: Hypertrophy of Lower Limbs and Atrophy[omicsonline.org]

  • Upper Motor Neuron Disease

    Myotonia is a slowness of relaxation of muscles after a voluntary contraction or a contraction provoked by muscle percussion.[dartmouth.edu] Symptoms include pharyngeal muscle weakness (muscles that are involved in swallowing), weak facial muscles, progressive loss of speech, and tongue muscle atrophy.[advancedpsy.com] Symptoms include pharyngeal muscle weakness (involved with swallowing), weak jaw and facial muscles, progressive loss of speech, and tongue muscle atrophy.[ninds.nih.gov]
