The olfactory function could be examined in 101 of 138 patients with anterior communicating artery aneurysms, whom we treated during a recent 6-year period. Among them, 49 patients underwent surgery by the anterior interhemispheric approach and 52 underwent surgery by the basal interhemispheric approach. Fifteen patients (31%) exhibited anosmia after(More)
We reviewed the surgical outcome in 85 patients with ruptured anterior communicating artery (ACoA) aneurysms, who were operated on within 72 hours of onset via a basal interhemispheric (BIH) approach (Group 1, N = 48), or an anterior interhemispheric (AIH) approach (Group 2, N = 37). The age, sex ratio and pre-operative grade (Gr) were similar for both(More)
OBJECTIVE The aim of the present study was to clarify differences between micro-vascular and iodine-staining patterns in the vicinity of the tumor fronts of superficial esophageal squamous cell carcinomas (ESCCs). METHODS Ten consecutive patients with ESCCs who were treated by endoscopic submucosal dissection (ESD) were enrolled. At the edge of the(More)
With the aid of flow cytometry (FCM), distribution of DNA content in 40 cases of brain tumour, primary culture cell, and secondary culture cell can be determined and chronological change after subculture is studied from the analysis of their cell cycle. In most primary cultures, proliferating index (PI) is likely to decrease, which suggests that(More)
We present a case of giant olfactory neuroblastoma with special reference to a new operative approach in cases of dumbbell-shaped tumor in the anterior cranial fossa. Our new approach is characterized as follows: resection of the bilateral orbital roof and frontal sinus en bloc, following bifrontal conventional craniotomy. Accordingly, retraction of the(More)
