Clinical evaluation of functional dysphonia.

Functional dysphonia is a voice impairment without any organic lesion of the phonating system. It may be classified into two categories: functional dysphonia itself where no lesions are found and functional laryngopathies where vocal cord lesions may be attributed to vocal abuse or misuse. The clinical evaluation of a dysphonic patient is performed in three steps: history taking, vocal evaluation, and examination. History taking helps the diagnosis and may be considered also as a therapeutic procedure. Vocal evaluation is oriented toward the voice itself and how it is produced. Then an ENT examination is performed with special attention to the larynx. In functional dysphonia, usually, everything looks normal but there may be signs of inflammation, hyperkinetism, hypokinetism, excessive laryngeal movements, etc. Functional laryngopathies include vocal nodules, laryngitis, polyps, and contact ulcer.

Diagnosis and treatment of intracordal cysts.

Seventy-one cases of intracordal cysts are reported. They were all diagnosed between 1970 and 1980: 53 were epidermoid and 18 retention cysts. They caused longstanding dysphonia characterized by lowered tonality, huskiness, desonorization, and vocal strain. Clinical signs were often discrete and stroboscopy revealed a lack of vibrations on the cystic cord. Surgery was followed by vocal re-education and there was a high percentage of good vocal results.

Hyperventilation and vertigo.

An electronystagmographic study was conducted on 19 normal subjects, in order to observe whether the subjective sensation of dizziness provoked by hyperventilation could be confirmed objectively by nystagmus. Each of them had two electronystagmograms, the first being a routine ENG and the second a repetition of the first, but with additional periods of 90 sec. of hyperventilation at certain precise pre-determined moments of the test. Hyperventilation was not shown to have significant effect on the slow phase of post caloric nystagmus; however, it increased significantly (p = 0.061) the number of positions in which nystagmus was elicited. Hyperventilation would have such an effect in producing a certain degree of cerebral hypoxia through cerebral vasoconstriction and the Bohr effect.

[Effect of hyperventilation on the vestibular system].

Nineteen normal subjects with no past history of hearing or balance impairment have undergone an electronystagmogram (E.N.G.), according to the usual technique in our laboratory. About one month or more after this first test, they underwent a second E.N.G. but this time with periods of hyperventilation distributed at certain precise moments of the test. Our analyses have not demonstrated that hyperventilation causes nystagmus or enhances in preexisting nystagmus in normal subjects, although the changes in the positional test were close to being significant.

Clinical and electronystagmographic findings in Friedreich's ataxia.

A thorough investigation of vestibular function has been carried out in 16 patients with typical Friedreich's ataxia. Electronystagmography and caloric tests revealed a number of inconstant abnormalities. Most abnormal findings were related to ocular dysmetria, disorganized pursuit and square waves.

[Audiovestibular study in Friedreich's ataxia].

A preliminary report is presented of the audiovestibular findings in 16 cases of typical Friedreich ataxia. Many ENG abnormalities of the central type were found, the most frequent being square waves, ocular dysmetria, and disorganized pursuit of the pendulum. The other abnormal findings were less frequent or less specific. Peripheral vestibular and auditory impairment were not the rule. Eventually, the electronystagmogram could become an early paraclinical screening test of Friedreich's disease.

[Basilar migraine].

Basilar migraine has been studied by Bickerstaff who considers that there is a vasoconstriction in the basilar territory resulting in transient ischemia with the corresponding neurological symptoms including vertigo, and followed by the vasodilatation causing the headache. Three cases, treated in neurology, have had an audiovestibular investigation with an E.N.G. and an audiogram and are described herein. Nystagmus and hearing loss have been observed in one of these cases and it is suggested that the internal auditory artery participates in the basilar migrainous processes. The diagnosis of basilar migraine is impossible to prove and the investigation is very limited. Finally it is the evolution of the patient which helps in establishing the diagnosis of basilar migraine.

Epidermoid cysts of the vocal cords.

Fifty-three cases of intracordal epidermoid cysts diagnosed, treated and followed from 1972 to 1981 are presented. In the clinical evaluation, special attention must be paid to the type of dysphonia and morphology of the vocal cords at indirect laryngoscopy. The epidermoid cyst is not easily visualized and the examiner must take into account signs like "monochorditis," slight bulging, unilateral nodule and diminished or abolished vibrations of one of the cords at stroboscopy. Microsurgical excision followed by voice therapy is the recommended treatment. The pathogenesis of these cysts is still speculative. Two theories are discussed: the traumatic theory and the dysembryoplastic theory.
