Surgical management of tegmen defects of the temporal bone …
In some patients, the tegmental region of the temporal bone can be interrupted, causing a tegmen defect (TD). A TD is sometimes associated with a meningoencephalic herniation (MEH), in which brain tissue herniates through a TD.
Management of tegmen defects with mastoid and epitympanic …
The repair of a tegmen bony defect with S53P4 bioactive glass granules seems to be a safe and effective technique, limiting the use of the middle cranial fossa approach to cases of epitympanic defects with an intact ossicular chain.
Tegmen tympani defect - LWW
A tegmen tympani defect is a tear in either the right or left side of the tegmen tympani, or the roof of the middle ear, which disrupts communication between the intracranial and extracranial sections. Any delay in diagnosis increases the risk of seizures, meningitis, encephalitis, or cerebral abscess. Figure. Ms. M is 60 years old with ...
Combined Approach for Tegmen Defects Repair in Patients with ...
The MCF approach permits tegmen defects located anteriorly (on the anterior attic tegmen) to be reached, allowing preservation of the ossicular chain. This surgical technique is especially indicated in patients with normal hearing function without middle ear/mastoid infection.
Repairing a Tegman Defect - CNC Hearing and Balance Center
2024年8月8日 · A tegmen defect is a gap in the bone between the brain and the ear. Repairing a tegmen defect is important because it decreases the risk of meningitis, an infection of the lining of the brain which can cause serious complications such …
Tegmen Attenuation and Dehiscence in Idiopathic Intracranial ...
Tegmen attenuation is the thinning of the tegmen tympani and/or tegmen mastoideum bones. Some authors theorize that the gradual thinning of the tegmen may eventually lead to dehiscence resulting in conductive hearing loss, meningoencephalocele, CSF leak, and otogenic meningitis.
Surgical management of temporal meningoencephaloceles ... - focus
Thinning of the tegmen tympani and mastoideum components of the temporal bone may predispose to the development of meningoencephaloceles and spontaneous CSF leaks. Surgical repair of these bony defects and associated meningoencephaloceles aids in the prevention of progression and meningitis. Intracranial hypertension may be a contributing ...
Diagnosis and operative repair strategy of an underlying tegmen defect ...
2021年9月1日 · The tegmen tympani and mastoideum are insidious locations of bony dehiscence. Large defects may result in encephalocele, cerebrospinal fluid leak, recurrent meningitis, and intracranial abscess. A rare complication is spontaneous otogenic pneumocephalus (SOP).
Cerebrospinal Fluid Leakage from Tegmen Tympani Defects Repaired …
2013年1月22日 · Spontaneous cerebrospinal fluid (CSF) otorrhea due to tegmen tympani defects can result in hearing impairment and predispose to meningitis. Seizures or neurological deficits are additional risks, particularly when associated with an encephalocele.
Temporal Bone Skull Base Defects—The Value and Importance of …
In the ideal value-based health-care setting, earlier radiographic identification of tegmen defects with specialist ear, nose, and throat (ENT) treatment, may prevent progressing to acute otogenic meningitis and its associated increased morbidity and mortality.
