As the CT findings of the temporal bone of latent acute mastoiditis are really same to that of middle ear cholesteatoma, it is considered that both diseases may be homologous, in which the supratubal recess route in the tympanic diaphragm is narrow or closed. Latent mastoiditis develops by the excretory dysfunction, and cholesteatoma develops by the ventilatory dysfunction via the tympanic diaphragm respectively. From this standpoint, the mysterious clinical sings and postoperative course of latent mastoiditis are easily understandable. In the treatments, CT examination with axial slicing and anterior tympanotomy in addition to mastoidectomy are recommended.

We investigated health-related quality of life (HRQOL) in patients with Bell's palsy. HRQOL questionnaire, SF-36 Japanese version 2, was filled out by 32 patients with Bell' s palsy at 3 weeks or later after the onset. The QOL scores were analysed twice in 15 patients within 7 days and about a month after the onset. No significant relation was observed between age and any of 8 subscales, however significant decrease was noted in 4 of 8 subscales in women, which were Role Physical (p=0.022), Bodily Pain (p=0.039), Mental Health (p=0.039), and Social Functioning (p=0.004). Patients with moderate and severe paralysis (score 832 on Yanagihara grading scale) tended to have lower scores in General Health (p=0.085), compared to the patients with mild paresis (score 34-40 on Yanagihara grading scale). Social Functioning significantly lowered about a month after the onset in comparison to those within 7 days from the onset (p=0.029). In conclusion, HRQOL in Bell' s palsy patients obtained by using SF-36 was promising, and especially Social Functioning (SF) was thought to be the most effective subscale for evaluation of QOL in Bell's palsy.

In this study, dynamic behavior of the basilar membrane and cochlear fluid caused by the vibration of the stapes was analyzed using a three-dimensional finite element model of the human cochlea. Numerical results and the measurement results were compared, and the validity of the model was verified. In addition, an influence of perilymphatic fistula on the vibration of the basilar membrane was analyzed. The leakage of the lymph from a perforation opened near the round window did not have the great influence on the vibration of the basilar membrane. In contrast, the amplitude of the basilar membrane decreased when the lymph flowed out through the perforation near the oval window. This result suggests that oval window perilymphatic fistula causes an increase of hearing threshold from the viewpoint of dynamics.

Endoscope is very useful for otosurgery of congenital cholesteatoma in children, because endoscopic observation can give a full view to find residual cholesteatoma in the tympanic sinus or behind the ossicles or to avoid any injury of the important structures. In the middle ear, there is a region where microscopic observation is very difficult due to the anatomical feature. It is very dangerous to perform otosurgery without adequate observation of these structures. We experienced 7 children with congenital cholesteatoma in the past 6 years and obtained good results. We reported a case of the youngest one that was the most difficult to inspect througout the middle ear cavity . Disadvantage of endoscope was that otosurgeon has to hold an endoscope with the left hand and handle forceps or suction tube with the right. It might be difficult to handle endoscope and surgical tools together in the narrow external canal. We think that otosurgeon needs some experience for endoscopic operation. Our conclusion was that endoscope should be used in otosurgery of cholsteatoma in children to perform safe operation with a full view of the middle ear cavity and to avoid to overlook the residual lesions .

In 2000, a new classification system of ossicular reconstruction was proposed by the Terminology Committee of Otological Society of Japan. We have often used this new classification to evaluate postoperative hearing after treatment by different surgical techiniques. In the present study, we assessed the postoperative outcome of Type III or IV tympanoplasty by measuring the hearing levels at various frequencies. A total of 357 ears (189 right ears and 168 left ears) in 160 male and 197 female patients aged from 6 to 74 years who were followed up for at least six months were studied. The surgical technique was Type III-c in 125 ears, III-i in 117 ears, IV-c in 63 ears, and IV-i in 52 ears. The success rate of these techniques was 75%, 83%, 43%, and 58%, respectively. Overall, tympanoplasty was successful in 69% (248/357) of the patients. In these 248 successful cases, the improvement of hearing was examined at various frequencies. Comparison of the techniques with respect to the improvement of average hearing after surgery showed no significant differences between any pair of techniques. Then the improvement of hearing at each frequency was compared. The results showed that there were no statistical differences at 250,500, or 1,000 Hz, but the Type IV-i technique tended to achieve better hearing at 2,000 Hz or higher frequencies and there was significantly better improvement than with the Type III-i technique. At 4,000 Hz, the Type IV-i technique provided significantly better hearing than both the Type III —c and II-i techniques.
