Observation and partial targeted surgery in the management of XXXX : a contribution to the multioptional treatment.

@entity1 @entity5 @entity75 @entity16 @entity2850 @entity1823
UNASSIGNED: The objective of this study was to assess the value of a limited @entity5 excision in @entity1823 treated with observation with the goal of preventing, or repairing, a @entity75 and continue an otherwise correct observation. This is a retrospective case review. Each @entity1 was submitted to a complete neuro-radiological work-up for diagnosis including CT, MRI, and angiography if needed of @entity1823 class C. All the cases were submitted to observation and in 16 cases partial targeted surgery was performed. In 10 cases, the procedure involved a targeted @entity5 growing in contact with, or invading, the Fallopius. In four cases, the procedure was a petro-occipital trans-sigmoid approach to remove the intradural portion of @entity5 producing the picture of @entity2850 . In two cases, there was the excision of the bleeding @entity5 surfaces in the outer ear canal. Follow-up ranged from 4 to 20  years. Success was considered the maintenance of observation without the change of class of @entity5 extension. In 13 over 16 cases, the observation could be continued, as it still was the more favorable option between natural and surgical morbidity. In the other three cases, a newly installed paralysis of the 9-10 cranial nerves due to @entity5 growth involved a correction of the strategy to a radical procedure. Partial targeted surgery was directed to cases submitted to observation. It allowed to prevent, or repair, an impending, or @entity16 or the brain stem and to continue the abstentional treatment by keeping the balance between natural and therapy morbidity in favor of observation.
