title: [Surgical treatment of tumors in anterior and middle skull base by modified maxillary bone disassembly procedures].
abstract: OBJECTIVE
  To explore the therapeutic effect of the modified maxillary bone disassembly procedures on patients with tumors in the anterior and middle skull base.
  
  
  METHODS
  Retrospective analysis was made of patients treated with the modified maxillary bone disassembly procedures. Ten tumors in the anterior and middle skull base were resected according to the pathology, size and site of the skull base tumors including 9 benign tumors and 1 malignant tumor.
  
  
  RESULTS
  All tumors were resected completely. All patients were followed up from 12 months to 5 years postoperatively. The complications were less and the life quality was increased. The patients with benign tumors showed no recurrence . Two patients with cerebrospinal rhinorrhea cured spontaneously after 7 days. One patient with melanoma died of brain metastase.
  
  
  CONCLUSIONS
  It is necessary to estimate the tumors thoroughly before surgery. According to the location of the tumor, the modified maxillary bone disassembly is the nearest and harmless approach, through which the tumors can be completely excised with minimal invasiveness. The life quality is thus increased.
