Clinical study referred to the nasal mucociliary transport of 132 healthy people, by means of the charcoal powder method. Intranasal clearance direction of the marker, the degree of the test's reproductiveness and the influence on the clearance of certain variables are considered. With this procedure the study of the nasociliary transportation time become simple, cheap, reliable, reproducible and objective. There are great individual variations of the nasal transport-time, but it is relatively constant in each examinee. The number of slow markers is scarce. The age, the sex, tobacco and the feminine cycle have no influential effect in the nasal mucociliary transport-time.

The paper deals with the research done by the AA. on the nasal mucociliary transport-time in a group of 30 children between 3 and 13-year-old. They employ the charcoal dust test. The powder is laid inside of the nose the day prior to the removal of the adenoids and investigated in the nasopharynx two weeks later. The conclusion drawn out is that among these children the mucociliary nasal transport time is retarded when compared with other children, turning over to the normality two weeks later.

Calcifying epithelioma of Malherbe (Pilomatrixoma) is a rare benign tumor, starting in the hair matrix and clinically resembling a hard subcutaneous swelling. The most common sites of localization are the head and neck regions. Women show a sizeable incidence. We report a case located in the prelaryngeal area and emphasize cytodiagnostic by fine needle aspiration. The correct treatment consists in pure and simply surgical excision under local anesthesia.

The sudden deafness is a common pathology with unilateral affectation and unknown etiology. Nowadays, the treatment is not completely clarified. We compare a urografin-CO2 treatment with CO2 as a single therapy.

A retrospective study was made of cavum malignant neoplasias. They were diagnosed and treated in the Ciudad Sanitaria Virgen de la Arrixaca (Murcia-Spain), between 1973 and 1982, with an epidemiological, clinical, anatomopathological, treatment and prognosis analysis. Cavum cancer is more common in men, with an average evolution time before the diagnosis about 4, 8 months, and an overall survival rate following treatment for every anatomopathological type about 32.4% after five years.
