Are growth alterations a consequence of surgery for prominent ears?

This study was undertaken to detect growth alterations after surgery for prominent ears. The cartilage excision technique was used in all 76 patients seen for follow-up. Two hundred students served as controls. Auricular measurements were done according to standardized guidelines of anthropometry. There was no significant difference in the retroauricular angle between the surgical group and controls. The morphologic ear length in the surgical group was significantly smaller than in controls. Maximum ear length was significantly greater in men. Our measurements in the control group were significant below the reference values reported in the literature. Comparing the ear index of both groups with published data, we found a harmony between the width and the length of the ear. We could demonstrate that prominent ears were significantly larger in all other dimensions and that auricular growth does not stop following surgery for prominent ears with the cartilage excision method. We also evaluated subjective criteria such as tolerance to cold, scar formation, and patient satisfaction.

[Functional and electromyographic long-term results following primary microsurgical repair of the recurrent laryngeal nerve].

Six patients with unilateral recurrent nerve paralysis underwent phoniatric follow-up after neurolysis or primary microsurgical repair of the recurrent laryngeal nerve. Four patients were controlled by electromyography of the vocal muscle 14 to 80 months post-operatively. In six patients the paralyzed vocal cords were in median to paramedian position with sustained muscle tonus. Phoniatric parameters were found to be close to the average range in healthy persons. EMG findings indicated degenerative neurogenous paralyses in two patients, signs of reinnervation in another. In one case biphasic action potentials could be recorded.

[Psychosocial effects of plastic surgery reconstruction of the female breast following amputation for malignant/benign tumor].

A total of 98 woman (malignant/benign tumors of the breast, mastectomy with/without subsequent reconstructive surgery as well as healthy controls) were examined in terms of subjective well-being, psychosomatic reaction patterns, subjective impairment due to mastectomy and satisfaction with the outcome of reconstructive surgery in this empiric retrospective study. In addition, numerous sociographic data were obtained. On the average, the examined women were satisfied with the outcome of reconstructive surgery and tended to be disappointed with regard to the desired psychosocial improvement. Objective tests demonstrate that subjective well-being was less favorable after reconstructive breast surgery than in women without reconstruction. In the group "benign tumor with subsequent reconstruction" the reaction to emotional strain was significantly more characterized by regressive behavior and withdrawal than in the group "benign tumor without reconstruction". In the group "malignant tumor with reconstruction" this difference was less pronounced. On the basis of these results we cannot confirm the assumption that reconstructive surgery of the breast has a supportive function.

[Isolated rupture of the vinculum longum superficiale (V1) following blunt trauma].

The anatomy and topography of the vincula are described. Their role in the blood supply to the flexor tendons is reviewed in the light of current reports. The authors present the case history of a 59-year old patient with blunt trauma to the middle finger of the right hand. This patient suffered from severe pain in the area of the proximal phalanx and the PIP joint of the third finger, as well as from reduced extension with a deficit of 20 degrees in the PIP joint. The differential diagnosis and clinical picture are discussed. The operative findings suggest a rare instance of detachment or rupture of the vinculum of the intact superficial flexor tendon.

[A rare combination of true and false aneurysm of the palm of the hand].

The authors report on a patient having a simultaneous true and false aneurysm along the superficial palmar arch. The clinical diagnosis was substantiated by ultrasound and angiography and the findings confirmed histologically. The classification of aneurysms according to their etiology and pathological anatomy is discussed. The clinical symptoms as well as alternative surgical procedures are illustrated with particular emphasis placed on the restoration of adequate peripheral blood circulation in the digits via microvascular anastomosis.

Sonoanatomy of the muscles of facial expression.

Primary anatomic studies served for identification and differentiation of the individual mimetic muscles. As a second step, we investigated the clinical potential of ultrasound imaging to visualize the mimetic musculature in 15 volunteers. This examination technique was used to diagnose pathological alterations, especially associated with facial palsy. The excellent sonographic visualization of the mimetic musculature indicates that this technique may be a valuable adjunct in the diagnosis and differentiation of facial palsy, as well as in planning plastic surgery and reconstructive procedures, and in follow-up care.

Photogrammetry of the muscles of facial expression.

The present study has attempted to determine the volume, square measure as well as length, width and thickness of the individual muscles of facial expression by photogrammetry. 15 fresh male head specimens were employed for a careful dissection of muscle layers. The volume was measured using the immersion procedure. The mean values of each parameter together with the standard deviation were summarized. The results suggest that this novelty in the representation of the mimetic muscles will facilitate the planning of corrective interventions in plastic surgery. Moreover, photogrammetry offers additional information on the required size and measurements of donor muscles.

[Clinical imaging of the mimetic muscles using high resolution ultrasound].

In comparison to other techniques, high resolution ultrasound has proved to be a good method for clinical imaging of muscles. By free selection of the scan plane and multidimensional viewing it is possible to represent each muscle from origin to insertion and to observe them during function. Pathology produces different types of echogenity. By imaging an EMG needle electrode the exact position within the muscle can be demonstrated. The result of the EMG study can therefore be related to small individual muscles or muscle segments, which are below the size suitable for clinical examination.

Sonoanatomy of the shoulder.

With the aid of ultrasound we tried to visualize the muscles of the shoulder region, the collum scapulae, the axillary artery and vein and the brachial plexus. We were successful with exception of the vessels and the nerves. Knowledge of the anatomical landmarks is essential in ultrasound image reading.

Sonography of the tongue and floor of mouth. Part I: Anatomy.

Normal structures of the tongue and floor of the mouth were studied using anatomic sections cut with a stainless steel band saw. The sections were performed on the same planes as used in US and CT scanning. The ultrasound studies were carried out with 20 young and healthy volunteers. CT images were obtained from head-neck preparations that were subsequently used for anatomic sectioning. On comparing these sections to US and CT images, normal structures including intrinsic and extrinsic tongue muscles, vessels and salivary glands were identified. Knowledge of the anatomic landmarks is mandatory for optimal US image reading.

Sonography of the tongue and floor of mouth.

The study about the sonoanatomy of the tongue and the floor of the mouth was undertaken with 20 volunteers. A description of the examination technique is given in comparison with computerized tomography. It is pointed out that it is easier to adjust the section planes optimally to the anatomical situation with ultrasound. This examination technique is noninvasive and easy to do. It is comfortable for the patient and can be repeated frequently, for example it allows a follow-up of cancer patients. Finally--this technique is cheap and can be performed at any given place.

[A procedure for the determination of spinal cord length in vivo].

Using anthropological methods, we measured the body height, length of the spine (ventral and dorsal), leg length, cord length. The data were evaluated statistically and we looked for correlation between leg length and body height, cord length and length of the spine, length of the spine and body height. On the basis of our results, we were able to determine the cord length for clinical use by computing the regression coefficient of leg length and spinal length.
