    In this study we analyzed the clinical features and surgical treatment of petrous cholesteatoma in 9 patients (9 ears) who underwent surgery at the Jikei University Hospital. Most patients initially experienced hearing loss, then facial nerve palsy or otorrhea. Congenital cholesteatoma was diagnosed in four patients, acquired cholesteatoma in one patient, and postoperative recurrence in three patients. The proportion of cases of congenital cholesteatomas was higher than in previous reports. The area of the cholesteatoma was classified according to Dr. Sanna cases and the supralabyrinthine type in two cases. Hearing preservation surgery was performed in four patients via the middle cranial fossa approach or by partial labyrinthectomy, and the results seemed satisfactory. These results suggested that hearing preservation surgery should be adopted in every case.

    Background: Intractable sinusitis is, in most cases, complicated by bronchial asthma and severe eosinophilic infiltration of the sinus mucosa. Our aim here was to study the postoperative outcomes of chronic sinusitis complicated/not complicated by bronchial asthma and of cases with eosinophilic sinusitis/non-eosinophilic sinusitis. Methods: We conducted a prospective analysis of the outcome of 180 patients with or without bronchial asthma and eosinophilic infiltration who underwent endoscopic sinus surgery (ESS) for chronic sinusitis. The patients were divided into four groups by the presence/absence of asthma and presence/absence of eosinophilic infiltration of the sinus mucosa. One surgeon performed the ESS, and all the groups received the same postoperative treatment. Results: The outcomes of ESS were significantly worse in the cases complicated by eosinophilic sinusitis and asthma, especially in relation to the incidence of smell disturbances and the endonasal findings. Patients suffering from chronic sinusitis without asthma showed good improvement following ESS. There was no significant differences in the outcome after ESS between cases of eosinophilic sinusitis and those with non-eosinophilic sinusitis among the patients without asthma. Conclusions: We contend that eosinophilic sinusitis without asthma may not represent intractable sinusitis. We wish to emphasize that complication by asthma is the most important predictive factor of the outcome of sinusitis after ESS.
