This is a report of two cases of intramedullary arteriovenous malformations (AVMs) where computed tomography (CT) was used as a complementary diagnostic investigation. CT scan features in these two cases are briefly discussed.

Correct identification and evaluation of balance disorders and an assessment of their repercussions on a patient's life are common problems faced by the otoneurologist. These symptoms may not infrequently have a chronic or recurrent course and can lead to in restrictions in the patient's everyday life and even have consequences for the patient' mental health. In the doctor-patient relationship anamnesis is of crucial importance in diagnosis as well as in establishing a relationship of professional confidence with the patient which may influence the outcome of the treatment. An awareness of those situations of daily life which bring about or aggravate the symptoms provides the doctor with valuable information in formulating an etiopathogenetic hypothesis. This observation led us to design the anamnestic self-questionnaire "Disability" whose purpose is to describe the type of disability or impairment to daily life suffered by the patient as a result of the pathology, while at the some time measuring their effects. Our history questionnaire has confirmed the importance of careful history in assessing balance disorders, has highlighted the striking extent of disability and impairment caused by these disorders, and has enabled us to identify the chief features of all pathologies encountered in the specific field of balance disorders. The questionnaire enables us, in particular, to highlight the interference of extra-vestibular factors (muscle-strain, states of irritation, phobias, drugs, dietary factors, etc.). The use of this questionnaire has proved to be of great assistance, therefore, in carrying out routine clinical diagnosis, in the absence of complex technical equipment. Moreover, it constitutes a valuable method in monitoring the outcome of the therapy, or the natural course of the balance disorders.
The aim of this study was to evaluate the influence of the cervical region and the stomatognathic system on the balance control. We examined 35 healthy subjects and 201 balance disorder patients; of the 201 patients 60 suffered also from craniomandibular disorders (CMD) and 40 from cervical rachis disease. All cases were tested by computerized stabilometry executed in Romberg position: with closed eyes, retroflexed head and two cotton roles between the dental arches. The results show that cervical rachis disease and stomatognathic dysfunction have a significative influence on the balance control; however, this influence is smaller than that of vestibular disease; moreover, the computer stabilometry allows to measure the degree of ascending or descending correlation between the posture and stomatognathic system.
We examined three groups: 29 patients suffering from balance disorders and craniomandibular disorders but from vestibular disease; 21 patients suffering from balance disorders, craniomandibular disorders and vestibular disease; 26 patients suffering from craniomandibular disorders but not from vestibular disease or balance disorders. All cases were examined by the odontologist and otoneurologist and tested by computerized stabilometry; they were reexamined after six months of therapy by an occlusal stabilization splint. The static analysis of the results show a significative reduction of the postural oscillations in all patients.
