Identification of the external branch of the superior laryngeal nerve during thyroidectomy.

Seventy-six patients underwent preoperative vocal evaluation and were randomized into 3 groups: (1) those with the superior thyroid pole dissected by the first author, with the external branch of the superior laryngeal nerve (EBSLN) identified by means of a nerve stimulator; (2) those patients whose dissection was executed by a resident, with no nerve search; and (3) those whose dissection was undertaken by the first author, without any nerve search. Postoperative analysis consisted of voice evaluation and electromyography of the cricothyroid muscle. No lesion occurred in patients in group 1. Twenty-eight percent of patients in group 2 and 12% in group 3 experienced a complete lesion of the EBSLN (p = 0.0123). When the patients in group 1 were compared with the patients with 62 nerves corresponding to nonoperated thyroid lobes, patients in group 1 exhibited no increased risk, whereas a significantly increased hazard was evident in both groups 2 (p = 0.0002776) and 3 (p = 0.0346393). In this study, effective prevention of iatrogenic EBSLN lesions during thyroidectomies was achieved only by the intraoperative identification of the nerve with the nerve stimulator.

Electromyographic study of the trapezius muscle in free movements of the arm.

The trapezius muscle (superior, middle and inferior portions) was analyzed in 20 volunteers. The electromyographic tests were carried out using a four-channel TECA TE 2-7 electromyograph with surface- and single coaxial needle electrodes. In abduction, adduction and flexion-extension, the 3 portions show increasing and decreasing activity, respectively, from the beginning until the end of these movements. In hyperextension, the 3 portions show increasing activity from the beginning until the end of the movement, with greater participation of the middle portion. Significant differences were not observed in the electromyographic profile of the trapezius, using surface and needle electrodes.

Electromyographic study of some muscles of the anterolateral abdominal wall.

The authors performed an electromyographic study on behavior of the rectus abdominis and the external and internal oblique muscles on 20 young healthy male volunteers during the performance of many movements of the trunk in the standing and supine positions. Concentric needle electrodes were used in connection with a model Te-4, Teca electromyograph of direct recording on paper. Among the results, stress is put on the fact that the oblique muscles revealed activity when the trunk was twisted to both sides with variable degrees of intensity. The rectus abdominis, that was expected to offer some support to the aponeuroses of the obliques in the trunk torsion, did not show action potentials during the performance of these movements. The action of these muscles in the flexion and extension of the trunk is also reported and discussed.

[Electromyographic analysis of the levator scapulae and rhomboideus major muscle in movements of the upper limb (author's transl)].

The participation of the levator scapulae and rhomboideus major muscles in some movements of upper limb was analysed in 21 young adult male volunteers. A 2 channel TECA TE 4 electromyograph connected with single coaxial needle electrodes was used. In abduction, elevation, adduction, flexion and circunduction occurred participation of both muscles in free movements of the upper limb. In extension, however, these muscles were inactive. In the same movements analysed with load, it was registered major intensity of action of these muscles as compared with those obtained in free movements.

Self-instruction in anatomy for medical students.

The authors describe the results of the use of a self-instructional material (study guide-book) during two Anatomy courses (cardio-respiratory and locomotor) given to first year medical students of São Paulo University. The rate of approval was considered very good in both courses.

Electromyographic study of the m. biceps brachii in movements at the glenohumeral joint.

Our electromyographic studies on the participation of the m. biceps brachii in the movements of the glenohumeral joint, performed in 20 young adult male volunteers, permit the following conclusions: (1) In the movement of arm flexion, performed against resistance and with extended elbow, both the long and the short heads of the m. biceps brachii were active in all 30 volunteers examined. (2) The same movement of the arm, arm flexion with extended elbow, now without resistance, that is to say performed freely, showed both the long and short heads of the m. biceps brachii active in the majority of cases. (3) In the movements of arm extension, performed freely and aganst resistance, with extended elbow, and also in the movement of lateral arm rotatin with flexed elbow, with and without resistance, the m. biceps brachii was absolutely inactive in all 30 volunteers examined. (4) In the movement of arm abduction, with extended elbow, the element of resistance to the performance showed itself to be important, since without it the m. biceps brachii was absolutely inactive; in the movement performed against resistance both heads of the muscle showed activity in 3 out of the 30 volunteers tested. (5) In the movements of arm abduction with and without resistance, with flexed elbow, the m. biceps brachii was active on occasion. (6) In the Movements of arm adduction against resistance, with the elbow either flexed or extended, it was only the short head of the m. biceps brachii which was active, and this in half of the cases examined. (7) In the movements of medical rotation of the arm, with extended elbow, performed freely or against resistance, the long and the short heads of the m. biceps brachii each showed a different behaviour: the long head was always inactive, whereas the short one was seldom active.
