[Ophthalmomimics. Polygraphic EMG study on oculo-facial simultaneous movements and functions of the autochthonous ear muscles].

Ophthalmomimic is the interaction between the extraocular eye muscles and the mimic muscles. Beside their original phylogenetic assisting function in looking and hearing, the ophthalmomimic muscles now serve in psychological communication: The play with the white of the eye ball can be interpreted as devotion ("to turn a blind eye to"); attention ("to be all eyes"); caution ("to have small eyes and to prick up one's ears"). Further on are examined function and innervation of the involuntary M. retro-auricularis (M. transversus auriculae) of the external ear, so far neglected. Practical diagnostic use could be shown, among others, in early ocular forms of myasthenic syndromes and by the help of the oculoauricular phenomenon for the differentiation between nuclear and peripheral-distal pareses of the abducens nerve.

[Electromyographic differential diagnosis in cases of abducens nerve paresis with nuclear or distal neurogenic sive myogenic origine (author's transl)].

Abducens nerve paresis may be of nuclear, of peripheral distal neurogenic origine, or is simulated by a myogenic weakness of abduction. Polygraphic emg analysis of the oculoauricularphenomenon (oap) permits a differentiation. In the emg, the oap proved to be a physiologic and constant automatic and always bilateral interaction between the hemolateral abducens nerve and both Nn. faciales with corresponding and obligatory coinnervation of the Mm. retroauricularis of the external ear. In case of medullary, nuclear or internuclear lesions, the oap is disturbed, instable, diminished or abolished, whereas in distal neurogenic or myogenic paresis, even in complete paralysis the oap is bilaterally well preserved.

[Paralytic abdominal hernia in zoster].

In a 56 year old patient with zoster in the thoracic segments 10 and 11 an abdominal hernia developed. The hernia was caused by peripheral motorial paresis.

Function and innervation of the involuntary m. retroauricularis.

Beside the automatic, obligatory and tonic coinnervation of the involuntary m. retroauricularis in conjugate lateral gaze (oculoauricular phenomenon, nystagmus) several other physiological ways of accidental coinnervation are described. In talking, chewing, swallowing and during involuntary inspiration irregular bursts of innervation may be registered. In sleep regular rhythmic inspiratory innervation is demonstrated as well as myoclonic jerks. With reservation, an allusion is made to rem-sleep. In "nervous subjects" irregular involuntary innervation of the m. retroauricularis might serve as a measurement instrument for the involuntary somatomotor nervous system, i.e. the degree of neurotic tensity. An early myasthenic reaction is gained from the M. retroauricularis in patients with ocular forms of the disease. A common motor nucleus of abducens and facial nerve is discussed. Complementary studies are announced on the various forms of facial paralysis, strabismus and nystagmus. A further diagnostic use is presumed.

[Congenital centronuclear myopathy. Two morphological variants in one family (author's transl)].

This report deals with a family in which the mother and her two daughters suffer from a congenital, slowly progressive neuromuscular disease. Histological, histochemical and ultrastructural observations of the mother's muscle biopsy reveal the characteristics of the centronuclear myopathy. In this case central nuclei and pericentronuclear abnormalities of muscle fibers are found in almost all fibers. Biopsies obtained of the two daughters show alterations especially of type I-fibers, which often are smaller than normal. The presence of these two forms of centronuclear myopathy in one family indicates that these may be only different morphological types of states of one illness. Additionally, other structural findings (rod bodies, core like regions) emphasize the similarities with other congenital slowly progressive myopathies (nemaline myopathy, central core disease).

[The oculoauricular phenomenon: a new reflex, a new muscle -- m. retroauricularis (polygraphic EMG study) (author's transl)].

On forced lateral gaze the outer and upper part of both ears is turned backward (oculoauricular phenomenon). A new, as far as we know, skin muscle of the external ear is described and called "m. retroauricularis". The oculoauricular phenomenon is a reflex mechanism between the abducens (m. rectus externus) and facial (m. retroauricularis) nerves. The verification of the automatic and tonic coinnervation is made polygraphically (EMG, stimulodetection) and clinically (unilateral abolition in case of homolateral facial paralysis). The oculoauricular reflex is a physiological and bilateral phenomenon, often rudimentary in man. It serves in looking, hearing and miming. The bilateral mechanism of innervation in the brainstem via the medial longitudinal fasciculus corresponds to Bell's phenomenon as to the "anti Bell".
