The glycerol test helps to establish the differential diagnosis between Ménière's disease and other vertigo disturbances, but the test becomes very long and in its primary form informs us only about the cochlear response to the osmotic changes produced by glycerol in the inner ear, and tells us nothing about the vestibular response. In patients with unilateral endolymphatic hydrops we have performed simultaneously the glycerol test with audiometric and craniocorpographic (CCG) control. The response of the vestibular apparatus to the glycerol becomes evident in 84.5% of cases on average in 30 min. By contrast, the variation in the hearing-threshold appears in only 54% of cases and required on average 60 min. At the same time, CCG is easier and shorter to perform than audiometry, showing five different types of response to glycerol. The combined use of audiometry and CCG allows us to predict with sufficient accuracy the response of the endolymphatic hydrops to the treatment, simplifying the therapeutic indication and the choice of the surgical technique.

The authors made a retrospective study of patients treated with laser CO2 in 1992 in the ENT. Clinic of the University Hospital of Puerto Real (Cádiz). The following parameters were considered: age, sex, province of origin, nature of the disease, type of surgical intervention, clinical evolutions and results to evaluate the efficacy of laser-therapy, its indications and its application limits. Furthermore, a comparison was made of these data and the their equivalents achieved during the five-year period 1986-1991. Indications, use of the laser CO2 and appropriate power for the pathological process and site of lesions were noted.
The results of craniocorpographic recordings in the Babinski-Weil test are discussed, focusing on the star-shaped variant. The variants of star-shaped gait are defined as posterior, centered, advanced, forward, extreme, and lateral. In 22 healthy individuals and 60 patients, star-shaped gait was the most common deviation. Extreme star-shaped gait was the most frequent variant in the healthy subjects and the backward variant was the most frequent in the patient group.
