BACKGROUND Bony wall damages in the region of the middle and posterior cranial fossa are usually observed in cases of chronic otitis media. These defects can also be congenital, post-traumatic, iatrogenic or due to tumors. They can potentially lead to the development of intracranial complications. MATERIAL/METHODS We analyzed patients who were diagnosed as having bony wall damage in the regio...

OBJECTIVES The central location and complex neurovascular structures of the posterior cranial fossa make tumor resection in this region challenging. The traditional surgical approach is a suboccipital craniotomy using a microscope for visualization. This approach necessitates a large surgical window and cerebellar retraction, which can result in patient morbidity. With the advances in endoscopi...

INTRODUCTION Dural defects and cerebrospinal fluid (CSF) leaks are a common problem following posterior fossa surgery. The management includes either nonoperative management (e.g. external lumbar drainage) or surgical re-exploration. OBJECTIVES We present our surgical, clinical and histopathological experience of dural closure in the posterior fossa. In order to avoid CSF leaks we developed a...

Posterior fossa syndrome is a severe transient loss of language that frequently complicates resection of tumors of the cerebellum. The associated pathophysiology and relevant anatomy to this language deficit remains controversial. We performed a retrospective analysis of all cerebellar tumor resections at Seattle Children's Hospital from 2010 to 2015. Diffusion tensor imaging was performed on e...

BACKGROUND Post-operative cerebrospinal fluid (CSF) leak in posterior fossa surgery remains a significant source of morbidity. TissuePatchDural (TPD), a novel impermeable adhesive membrane, was used to reinforce dural closure. A comparison with one of the most commonly used dural sealing devices, DuraSeal, has been made. METHODS A retrospective, single-center study was conducted on 161 patien...
