Hearing loss is a highly prevalent disease state affecting almost 1 in 5 individuals globally. Growing research shows that untreated or undertreated hearing loss carries significant long-term sequelae, including increased risk of social isolation, depression, and cognitive decline, among other ramifications. Limited awareness and common misperceptions among the general US adult population and primary care providers contribute to low rates of referral to hearing specialty clinics and underutilization of hearing aids, cochlear implants, and other rehabilitative devices. Comprised of diverse membership, the Hearing Health Collaborative (HHC) was formed in May 2021 to identify and overcome challenges impacting good health care practices and public policy on hearing care in connection with healthy aging. This editorial documents a recent outcome of the HHC derived from a structured A3 process. Specifically, initiative 2, a proposal to develop a simple, clinically anchored staging system primarily for use by frontline providers and patients, is presented. Unlike other common disorders that harbor long-term health sequelae, a corresponding pragmatic clinical staging system—leveraging precedent disease staging convention, based on clinically meaningful outcomes and prognosis for acquired hearing loss—does not exist. The development of this staging system will potentially allow for improved communication across providers and patients, facilitate referral pathways, and ultimately enable patient access to timely and appropriate care.

Objective Present the rationale for the development of a new, patient-facing vital sign for adult hearing. Study Design Structured A3 process. Setting Fourteen virtual meetings and two in-person meetings held between May 2021 and June 2022. Main Outcome Measure(s) Identification and refinement of a countermeasure to develop and imbed a hearing health vital sign for adult hearing. Results Through a rigorous, structured A3 process, the Hearing Health Collaborative identified and refined the rationale for and the qualities associated with a public-facing vital sign for adult hearing loss. Specifically, such a vital sign must embody five qualities: simple, accessible, stable, inclusive, and meaningful. These qualities together would ensure that a hearing health vital sign would be useful not only as a screening tool but also as an instrument to guide next steps in workup and potentially treatment. Conclusions Successful identification and implementation of a hearing metric or “vital sign” for the presence of adult hearing loss, using precedent convention of other medical diseases, may help reframe public perceptions surrounding hearing loss, improve awareness and literacy regarding the presence of the disease, and prompt action to seek diagnostic assessment.

ABSTRACT Over the past two decades, there has been increasing interest in the diagnosis and management of schwannomas of the inner ear including hearing rehabilitation with cochlear implants. However, tumor nomenclature and classification within the literature have been variable and oftentimes cumbersome. The term “intralabyrinthine schwannoma” is in common use when describing these tumors but is a potential source of confusion given that people often use the term “labyrinth” or “labyrinthine” to refer to the vestibular component of the inner ear only (i.e., labyrinthectomy or the translabyrinthine approach). During the Ninth Quadrennial Conference on Vestibular Schwannoma and Other Cerebellopontine Angle Lesions in Bergen, Norway, in May 2023, a multidisciplinary group of conference participants met and discussed issues pertaining to current terminology and classifications to enhance clarity and to reflect recent advances in tumor management and hearing rehabilitation. Although a variety of terms have been previously used to describe inner ear schwannomas, consensus was achieved on the term “inner ear schwannoma (IES)” to describe eighth nerve schwannomas of the cochlea, vestibule, or semicircular canals. Subgroups under this term comprise intravestibular, intracochlear, or intravestibulocochlear inner ear schwannomas (low complexity tumors), inner ear schwannomas with transfundal extension into the internal auditory canal but without modiolar involvement (intermediate complexity tumors), and inner ear schwannomas with transfundal extension with modiolar involvement (high complexity tumors). The details of the recommendations for an updated and simplified tumor nomenclature centered around tumor control and hearing rehabilitation with cochlear implantation are presented.
