A Clinical study for otorhinological symptoms and signs in head trauma was done with 1927 head trauma patients who admitted in this college hospital or visited to our department during the period of Jan. 1967 to Dec. 1970. The results obtained are summarized as follows : 1) The ratio of head trauma between male and female was 2.1 : 1. 2) The head trauma had occurred most frequently in the first decade and been less as the age getting older. But, the mortality due to the trauma was reverse. 3) A variable period of unconsciousness appeared in 59.6% of patients and more or less this sign seemed to influence on the prognosis of the head trauma. 4) Among 1927 patients, 778 cases (40.4%) had skull fractures. The mortality rate was 6.2% in concussion cases without fractures and 22.5% in skull fractures. 5) The most frequent symptom in otorhinological field was the nose bleeding. (265 cases, 13.9%). The nose bleeding itself had no clinical significance but had very important roles on the prognosis of the head trauma when it combined with ear bleedings. 6) 205 cases (26.3%) showed ear bleedings and 64 cases (8.2%) had hematotympanum in 778 cases of skull fractures, but these signs were not the difinite indication to make the type of the fracture of the temporal bone, since there were many cases which had both signs at the same time. 7) There were only 97 cases (5.0%) who complained of subjective hearing loss due to the head trauma. Most of them showed a sensory-neural type deafness. 8) Facial paralysis appeared in 22 cases (1.1%) and a half on them returned normal function spontaneously. 9) Only 153 cases (7.9%) complained of vestibular disturbances and a few of them visited our clinic. 10) The olfactory disturbance appeared in only 4 cases (0.2%). 11) Generally, the ENT specialists are rarely called in treatments of head trauma or ofter totally neglected by the meurosurgeons. This makes hard to evaluate the real state of otorhinological problems due to the head truma. The otorhinologists should be more active and familiar to examine and treat head trauma patients.
