Treatment of tegmen dehiscence using a middle fossa approach …
Surgical management of tegmen dehiscences (TDs) can help prevent these symptoms. In this manuscript, we present one of the largest reported single team experiences of using a temporal craniotomy with middle cranial fossa approach and temporalis fascia graft in the treatment of tegmen defects.
Surgical management of tegmen defects of the temporal bone …
This paper presents our experience regarding surgical outcomes for the treatment of TD and/or MEH based on patient characteristics, such as age, preoperative hearing threshold, the presence of comorbidities, and history of recurrence despite previous surgery, considering TD and/or MEH characteristics in terms of size and location.

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.
