Vibration of tympanic membranes of the middle ear model with TORP and flat membrane made of gum were studied by means of holographic interferometry. Results were as follows. 1) As the tension of the gum became high, the amplitude decreased in low frequency. The segmental vibration was observed in low frequency as the tension became low. 2) The difference between 0.03mm and 0.06mm was not signif...
OBJECTIVES To assess whether a classification system for congenital cholesteatoma (CC) can be derived from analysis of a large clinical sample of cases and to assess whether such a classification system is a reliable guide for surgical intervention, reexploration, and hearing outcome. DESIGN A retrospective review of clinical and surgical records of 119 patients with CC. SETTING Four tertia...
The effect of parent involvement in the treatment of anxiety disorders in children: a meta-analysis.
Among clinicians, it is common practice to include parents in treatment, and it has been taken for granted that parents' involvement in their children's treatment is beneficial for therapy outcome, although research on this issue is far from clear. A meta-analysis was carried out in order to investigate whether parent involvement potentiates the outcome for children with anxiety disorders when ...
This is a retrospective review of congenital cholesteatoma cases that were managed surgically. There were 5 cases. The age of presentation ranged from 5 to 18 year old. Three patients presented with complication of the disease. Three patients had intact tympanic membrane, two had perforation at the anterior superior quadrant. All patients had cholesteatoma medial to tympanic membrane. Four case...
Besides eradication of chronic middle ear disease, the reconstruction of the sound conduction apparatus is a major goal of modern ear microsurgery. The material of choice in cases of partial ossicular replacement prosthesis is the autogenous ossicle. In the event of more extensive destruction of the ossicular chain diverse alloplastic materials, e. g. metals, ceramics, plastics or composits are...
