Temporal lobe encephaloceles are characterized by protrusion of brain parenchyma through a structural defect in the floor of the middle fossa. They have been reported to cause cerebrospinal fluid (CSF) leaks, conductive hearing loss, meningitis, and seizures. The association between temporal encephaloceles and epileptiform activity is particularly rare. ⋯ Temporal lobe encephaloceles are an infrequent cause of seizures. Given that these lesions can be missed with standard imaging modalities, they are likely underdiagnosed upon initial medical evaluation. This diagnosis should be considered in patients with intractable seizures. If an encephalocele is found, focused resection of epileptogenic tissue associated with herniation and repair of the temporal floor defect can provide definitive treatment.

An inexpensive temporal bone model for use in a temporal bone dissection laboratory setting can be made using a commercially available, consumer-grade 3D printer. ⋯ A realistic, inexpensive, and easily reproducible temporal bone model can be created on a consumer-grade desktop 3D printer.

To assess improvements in sound source localization and speech understanding in complex listening environments after unilateral cochlear implantation for single-sided deafness (SSD). ⋯ Cochlear implantation for SSD can offer improved speech understanding in complex listening environments and improved sound source localization in both children and adults. On tasks of sound source localization, SSD-CI patients typically perform as well as BCI patients and, in some cases, achieve scores at the upper boundary of normal performance.

Active middle-ear implants with floating-mass transducer (FMT) technology are used to treat mild-to-severe sensorineural hearing losses. The standard surgical approach for incus vibroplasty is a mastoidectomy and a posterior tympanotomy, crimping the FMT to the long incus process. An alternative fixation side with less surgical trauma might be the short incus process and incus body.The aim of this study was to develop and test a short incus process coupling device for its functional properties in temporal bone preparations and clinical practice. ⋯ The attachment of the FMT to the short incus process with the SP2 coupler leads to good mechanical and functional coupling in an experimental setup and clinical practice.

To evaluate the short-term efficacy of computer-controlled and modified roll maneuver (CMRM) versus conventional roll maneuver (RM) for treatment of geotropic lateral canal benign paroxysmal positional vertigo (BPPV). ⋯ The CMRM consisting of three sequential 360-degree rotations for geotropic lateral canal BPPV has a higher initial success rate compared with the conventional RM consisting of one 360-degree rotation.
