This paper presents a comparison of two versions of an Emergency Automated Response System (EARS), a fully manual version and a partially automated version. User evaluations involving both versions of the system were conducted using a low workload task and a high workload task. The results indicate that the automation employed by the partially automated system decreased overall response time an...

4-year retrospective study was performed in 152 children (279 ears) with secretory otitis media (SOM) in order to evaluate the long-term result with grommets. In 158 ears which were well controlled by grommets, the mean duration of treatment was 13.8 months. The tube was inserted once in 98 ears (62%), twice in 31 ears (20%), three times in 19 ears (12%) and four times or more in 10 (6%). Otosc...

Pneumatization of the petrous apex was investigated in 226 subjects without middle ear disease by means of target imaging CT. The degree of pneumatization of all subjects was 32.7% (148/452 ears), but no difference in degree was revealed with distinction of bilateral ears or between sexes. In 148 ears with pneumatization of the petrous apex, a higher degree of pneumatization was found in larger...
