OBJECTIVE: To summarize the characteristics of the pathological anatomy and blood supply model of massive @entity1653 (MTSM) and explore its corresponding microneurosurgical strategies. METHODS: The clinical data of 16 MTSM @entity1 were reviewed retrospectively. From January 1998 to January 2010, according to their unique pathological anatomy and blood supply model, all @entity1 underwent microneurosurgical removal with induced @entity551 through @entity5 corridor by the bi-subfrontal anterior longitudinal fission (n = 14), right frontolateral approach (n = 1) and pterional approach (n = 1). There were 5 males and 11 females with a mean age of 48.5 years old (range: 26 - 65). But the mean follow-up period was 74.9 months (range: 4 - 132) in 2/4 cases. RESULTS: Among all cases, the mean @entity5 diameter was 58.9 mm (range: 51.1 - 76.2 mm). Simpson grade I, II, III, IV removal of MTSMs were accomplished in 3, 9, 3 and 1 case respectively. One case died within 4 postoperative days. Visual acuity improved in 10 @entity1 , remained unchanged in 2 and deteriorated in 2. Transient @entity2010 occurred in 9 cases. CONCLUSION: It is critical to understand the unique characteristics of pathological anatomy and blood supply model of MTSM so as to adopt proper microneurosurgical strategies to remove it in situ.
