Temporal lobe injury with middle fossa approach to intracanalicular vestibular schwannomas: a systematic review.

There are several surgical approaches for vestibular schwannoma (VS) resection. However, management has gradually shifted from microsurgical resection, toward surveillance and radiosurgery. One of the arguments against microsurgery via the middle fossa approach (MFA) is the risk of temporal lobe retraction injury or sequelae.

The relationship of inter-implant time and hearing outcomes for bilateral cochlear implants.

Purpose: Determine the relationship between time elapsed between sequential bilateral cochlear implantation (BiCI) and speech intelligibility scores in post-lingually deafened adults.

Materials And Methods: Retrospective review of post-lingually deafened adults who received bilateral cochlear implants from January 1, 2011 to January 1, 2018 at an ambulatory tertiary referral center.

Results: 113 patients (226 cochlear implants) were initially reviewed, with 56 patients (112 implants) being included in the final analysis.

En bloc resection of the temporal bone and temporomandibular joint for advanced temporal bone carcinoma.

Advanced skin malignancies involving the temporal bone can involve the temporomandibular joint and glenoid fossa. Many of these tumors can be removed with a lateral temporal bone resection; however, extensive involvement of the glenoid fossa should include an en bloc resection of the temporal bone, glenoid fossa, and condyle. We describe a novel surgical approach that is an extension of a temporal bone resection that includes the glenoid fossa and condyle in an en bloc resection with the temporal bone.

Cochlear implantation requiring a retrofacial approach to the round window.

Objective: To describe three cases of cochlear implantation utilizing a retrofacial approach to the round window.

Study Design: Retrospective case review.

Patients: Three patients with sensorineural hearing loss undergoing cochlear implantation.

Recurrent meningitis secondary to a petrous apex meningocele.

This case report describes a patient who was found to have a cerebrospinal fluid (CSF) leak originating from the petrous apex. The patient initially presented with multiple bouts of meningitis. The patient was treated surgically via a middle cranial fossa approach but presented five years later with recurrent meningitis and was found to have an osseous defect of the petrous apex which was not recognized prior to the initial surgery.

The association of meningitis with postoperative cerebrospinal fluid fistula.

Objective To determine the risk factors for and the clinical course of postoperative meningitis following lateral skull base surgery and to determine its relationship to cerebrospinal fluid (CSF) fistula. Patients Patients undergoing lateral skull base surgery between July 1999 and February 2010 at an academic tertiary referral center. All subjects had culture-proven meningitis or suspected bacterial meningitis in the postoperative period.

Intratemporal traumatic neuromas of the facial nerve: evidence for multiple etiologies.

Objective: To describe 2 patients with traumatic neuromas of the intratemporal facial nerve in the absence of trauma.

Study Design: Retrospective case review.

Setting: Tertiary care referral center.

Elevated intracranial pressure in patients with spontaneous cerebrospinal fluid otorrhea.

Objectives/hypothesis: To determine the prevalence of elevated intracranial hypertension in patients with spontaneous cerebrospinal fluid otorrhea (SCSFO).

Study Design: Case series with chart review at a tertiary care academic medical center following institutional review board approval.

Methods: A retrospective review was performed of patients undergoing operative repair of SCSFO between January 2007 and May 2012.

Superior semicircular canal dehiscence in patients with spontaneous cerebrospinal fluid otorrhea.

Objective: To determine the prevalence of superior semicircular canal dehiscence (SCD) in patients with spontaneous cerebrospinal fluid (CSF) otorrhea.

Study Design: Case series with chart review.

Setting: Tertiary care referral center.

Lumbar subarachnoid drainage in cerebrospinal fluid leaks after lateral skull base surgery.

Objective: To determine the efficacy of lumbar drainage in managing cerebrospinal fluid (CSF) leak after lateral skull base surgery.

Study Design: Retrospective case review.

Setting: Academic tertiary referral center.
