[Position paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - current state of clinical and endoscopic diagnostics, evaluation, and therapy of swallowing disorders in children and adults]

Position Paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - Current State of Clinical and Endoscopic Diagnostics, Evaluation, and Therapy of Swallowing Disorders in Children and AdultsSwallowing disorders are frequent. The main concern is mortality due to aspiration induced pneumonia and malnutrition. On the other hand quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract and sequelae of tumor treatment in the head and neck region are the main pathologic entities.Predominantly ENT physicians and phoniatrists, are asked for diagnostics and therapy who will coordinate the interdisciplinary treatment according to the endoscopic findings.A differentiated approach in history, diagnostics, and symptom oriented treatment is necessary for the mostly complex disorders. The integration of non-medical personnel such as logopeds (speech language pathologists), physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over by them in close cooperation.In particular an interdisciplinary cooperation with the staff from intensive care medicine is indispensable.The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists.Endoscopy is a medical service that is basically not delegable. Consequently substitution of the physician is precluded.

[Changes in dose and injection pattern in the botulinum toxin long-term therapy of facial dyskinesis]

BACKGROUND

Rare information exists about comparative long-term observations of patients with facial movement disorders. This retrospective analysis deals with the course of different parameters of injection over the time.

METHODS

In this study we compared the development of long-term botulinum toxin treatments of patients with blepharospasm, hemifacial spasm and synkinesis. 80 patients (n=30 blepharospasm, n=31 hemifacial spasm, n=19 synkinesis), who had at least 10 consultations for BTA-injections, were included in the retrospective analysis. The development for each entity in total dosage, increase in the number of injection points and change in dosages for each point were evaluated.

RESULTS

The over-all dosage in all 3 clinical disorders and for each single disease itself increased continuously over the time. The amount of injection points increased in the treatment of hemifacial spasm and synkinesis. The dosage per point increased most in blepharospasm between the 1. and 25. injection, but was distinctly lower in patients with hemifacial spasm and synkinesis. The increase in dosage in blepharospasm is therefore, in contrast to the other indications, mostly caused by an increase in dosage per point. In patients with hemifacial spasm and synkinesis the escalation of dosage is mainly caused by an increase of the number of injection points.

CONCLUSION

These new aspects of the dynamic in the treatment with botulinum toxin enable the physician to understand better the dynamic of these diseases, to optimize treatment protocols.
