Auditory Brainstem Implantation: An Overview.

J Neurol Surg B Skull Base 2019 Apr 14;80(2):203-208. Epub 2019 Feb 14.

Department of Otolaryngology-Head and Neck Surgery, New York University School of Medicine, New York, New York, United States.

An auditory brainstem implant (ABI) is a surgically implanted central neural auditory prosthesis for the treatment of profound sensorineural hearing loss in children and adults who are not cochlear implant candidates due to a lack of anatomically intact cochlear nerves or implantable cochleae. The device consists of a multielectrode surface array which is placed within the lateral recess of the fourth ventricle along the brainstem and directly stimulates the cochlear nucleus, thereby bypassing the peripheral auditory system. In the United States, candidacy criteria for ABI include deaf patients with neurofibromatosis type 2 (NF2) who are 12 years or older undergoing first- or second-side vestibular schwannoma resection.

Cochlear Implantation for Single-Sided Deafness: A New Treatment Paradigm.

J Neurol Surg B Skull Base 2019 Apr 4;80(2):178-186. Epub 2019 Feb 4.

Department of Speech and Hearing Science, Arizona State University, Tempe, AZ, United States.

Unilateral severe-to-profound sensorineural hearing loss (SNHL), also known as single sided deafness (SSD), is a problem that affects both children and adults, and can have severe and detrimental effects on multiple aspects of life including music appreciation, speech understanding in noise, speech and language acquisition, performance in the classroom and/or the workplace, and quality of life. Additionally, the loss of binaural hearing in SSD patients affects those processes that rely on two functional ears including sound localization, binaural squelch and summation, and the head shadow effect. Over the last decade, there has been increasing interest in cochlear implantation for SSD to restore binaural hearing. Read More

Hearing Preservation in Stereotactic Radiosurgery for Vestibular Schwannoma.

J Neurol Surg B Skull Base 2019 Apr 10;80(2):156-164. Epub 2019 Jan 10.

Department of Otolaryngology, University of Texas Southwestern Medical Center, Dallas, Texas, United States.

Despite no universally accepted definition of hearing preservation following vestibular schwannoma (VS) treatment, numerous variables have been identified as possible factors that may affect hearing outcomes following radiotherapy. Age, pretreatment hearing, radiation dose, tumor location and size, length of follow-up, fractionation, and timing of radiation have all been explored, among other variables, as factors related to hearing outcomes following radiation. These variables and associated hearing outcomes will be explored in detail, summarizing the literature to date to improve patient counseling for those patients who present with serviceable hearing and are considering their VS management options.

Tinnitus Management in Lateral Skull Base Lesions.

J Neurol Surg B Skull Base 2019 Apr 30;80(2):125-131. Epub 2018 Nov 30.

Department of Otolaryngology-Head and Neck Surgery, The University of Michigan, Ann Arbor, Michigan, United States.

Tinnitus, the phantom perception of sound in the absence of a physical sound source, is a complex problem with multiple etiologies. While most commonly presenting in a subjective fashion caused by measurable hearing loss, other etiologies including lateral skull base tumors that encroach on middle and inner ear structures can lead to phantom sound perception as well. In addition to discussing the basic background of tinnitus, here we also review current theories of etiology that include central auditory and nonauditory neural mechanisms and potential treatments that range from sound therapy to medications to cognitive and behavioral therapies and cranial nerve and brain stimulation.

CXCR4 and PD-1 Expression in Head and Neck Cancer with Perineural Spread.

J Neurol Surg B Skull Base 2019 Feb 14;80(1):18-22. Epub 2018 Jun 14.

School of Medicine, University of Queensland, Brisbane, Queensland, Australia.

 Perineural spread (PNS) is a marker of aggressiveness and has been shown to occur in cranial nerves due to advanced mucosal and cutaneous head and neck cancer. Receptors CXC chemokine receptor 4 (CXCR4) and programmed cell death-1 (PD-1) have been shown to be overexpressed in a variety of cancers with PNS, with the inhibition of these pathways offering a potential future treatment.  Retrospective immunohistochemical staining for the CXCR4 and PD-1 receptors was performed on 28 head and neck specimens that demonstrated PNS from January 2017 to August 2017, at Royal Brisbane and Women's Hospital, Brisbane, Australia.

Proposal for Modification of Cahan's Criteria Utilizing Molecular Genetic Analyses for Cases without Baseline Histopathology: A Unique Method Applicable to Primary Radiosurgery.

J Neurol Surg B Skull Base 2019 Feb 31;80(1):10-17. Epub 2018 May 31.

Department of Otolaryngology-Head and Neck Surgery, Mayo Clinic, Rochester, Minnesota, United States.

 Cahan's criteria have been utilized since 1948 to establish causality between prior radiation treatment and the development of secondary malignancy. One major criterion specifies that histological and radiographic evidence collected before and after radiation treatment must confirm separate tumor types; however, pretreatment biopsy is rarely obtained prior to radiosurgery for vestibular schwannoma and many other skull base and cranial lesions. Therefore, in these cases Cahan's criteria cannot be validly applied. Read More

Microsurgical Decompression of Trigeminal Neuralgia Caused by Simultaneous Double Arterial (SCA and AICA) and Petrosal Vein Complex Compression.

J Neurol Surg B Skull Base 2018 Dec 25;79(Suppl 5):S428-S430. Epub 2018 Sep 25.

Semmes Murphey Neurologic and Spine Institute, Memphis, Tennessee, United States.

Trigeminal neuralgia is a chronic pain disorder affecting the face. In approximately 80% of cases, it is most commonly caused, when the root entry zone (REZ) of the trigeminal nerve is compressed by the superior cerebellar artery (SCA). The etiology of the remaining 20% of cases is distributed among venous, arteriovenous malformations, posterior fossa tumors, multiple sclerosis plaque compressions, and other pathologies. Read More

 Surgical resection is the only effective treatment modality for epidermoid tumors. Complete resection with preservation of neurological function must be pursued whenever possible, because it offers a cure for patients. However, the inability to identify hidden remnants, interdigitating around cranial nerves, especially in larger tumors, may be a contributing factor for incomplete resection. Read More
