[Postoperative regression speed of chronic subdural hematoma, with special reference to the subsequent study by CT xray].

Thirty-one adult patients with chronic subdural hematoma were treated surgically and followed Up by CT. In these cases, the postoperative regression of the hematoma cavity on CT was analysed in relation to patient's age, timing of operation, operative method, preoperative CT findings and postoperative clinical courses. In patients with older age and/or low density type of hematoma, slow reduction of subdural space was observed after operation. In five of these cases, the follow-up CT scans revealed reaccumulation of hematoma. Patients with high density type of hematoma and/or early operation from the onset showed a rapid reduction of hematoma cavity and clinical improvement.

Ciliary activity on adenoids of patients with otitis media with effusion.

Ciliary activity of the adenoidal surface in patients with otitis media with effusion (OME) was evaluated by a photoelectric method. Three groups of patients were compared: a non-OME group whose members had experienced no episode of OME; a middle ear effusion (MEE)-negative OME group whose members had an episode of recurrent OME but no MEE during the month preceding the operation; and an MEE-positive OME group whose members were experiencing an episode of recurrent OME with MEEs when tissue was taken for examination. To serve as a comparison, the ciliary activity in the central pharynx of normal guinea pigs was evaluated using the same technique. The ciliary activity in all patients was significantly lower than that in normal guinea pigs. No significant difference in ciliary activity was apparent between the non-OME group and the MEE-negative OME group. However, both were significantly higher than the ciliary activity of the MEE-positive OME patients. The following findings are drawn from our data: ciliary activity on the surface of hypertrophic adenoids is depressed, and patients with OME have reduced ciliary activity compared with those who have no otitis media or those who have otitis media without effusion.
