Repair of Tegmen Tympani Defect Presenting with Spontaneous Cerebrospinal Fluid Otorrhea Using the Middle Cranial Fossa Approach.
Spontaneous cerebrospinal fluid (CSF) otorrhea frequently occurs without temporal bone trauma, fracture, surgery, or any identifiable causes. It is usually associated with tegmen tympani defects of the temporal bone in adults. The congenital origin theory and the arachnoid granulation theory have been accepted to explain the tegmen tympani defect. Magnetic resonance imaging (MRI) and computed t...
متن کاملA novel method for autograft placement during tegmen repair: the suture "pull-through" technique.
INTRODUCTION Temporal bone encephaloceles and cerebrospinal fluid (CSF) leaks are associated with an increased risk of life-threatening intracranial infection. Defects in the floor of the middle cranial fossa are attributed to prior infection, trauma, iatrogenic injury, and increased intracranial pressure. In the temporal bone, intracranial contents most commonly pass through dehiscences in the...
متن کاملCalcified Middle Cranial Fossa Mass
A 21-year-old male presented for evaluation of transient loss of consciousness and was found to have a hyperdense mass in the left middle fossa. He underwent craniotomy for tumor resection. Intra- and extradural invasion was noted. Gross total resection was achieved. Pathology demonstrated a densely cellular neoplasm with predominately spindle cell morphology in a collagen-containing stroma, ar...
متن کاملFeasibility Assessment of Optical Coherence Tomography-Guided Laser Labeling in Middle Cranial Fossa Approach
Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory ...
متن کاملVidian nerve schwannoma with middle cranial fossa extension resected via a maxillary swing approach.
BACKGROUND Vidian nerve schwannoma is an extremely rare type of facial nerve schwannoma. To the best of our knowledge, only 1 case has been reported. METHODS We report an additional case of vidian nerve schwannoma with middle cranial fossa extension in a 49-year-old Japanese woman. The surgical approaches for infratemporal fossa schwannomas are reviewed, and the maxillary swing approach we us...
