Effect of Rurality in Head and Neck Cancer: A Scoping Review.

OBJECTIVES: This scoping review sought to evaluate the current literature regarding the following outcomes in relation to rurality: stage at diagnosis, clinical characteristics, treatment characteristics, and survival outcomes of head and neck cancer (HNC). DATA SOURCES: A literature search was performed using PubMed (MEDLINE), Science Direct, EMBASE, SCOPUS, and Web of Science databases. REVIEW METHODS: A 20-year study cutoff from the initial search was used to increase the comparability of the studies regarding population and standards of clinical care. These searches were designed to capture all primary studies reporting HNC incidence, presenting characteristics, treatments, and treatment outcomes. Two reviewers independently screened abstracts, selected articles for exclusion, extracted data, and appraised studies. Critical appraisal was done according to the Joanna Briggs Institute Quality Assessment Tool for Cohort Studies. FINDINGS: Twenty eligible original articles were included. Stage at diagnosis, clinical characteristics, treatment characteristics, and survival outcomes were measured. Our review indicates that although this relationship is unclear, there may be variations in treatment choice for laryngeal cancer based on geographic location and rural residency status. The studies assessing HNC outcomes related to stage at diagnosis, clinical characteristics, treatment characteristics, and overall survival demonstrated conflicting findings, indicating a need for further research examining HNC outcomes with a focus on rurality as the main exposure. CONCLUSIONS: The relationship between HNC and rural-urban status remains unclear. More studies are needed, along with a consistent metric for measuring rurality and recruitment of comparable populations from both rural and urban areas. Laryngoscope, 2024.

Bifid Intratemporal facial nerves in an adult without other congenital anomalies.

Objective: To describe a case of bifid intratemporal facial nerves without associated middle or inner ear abnormalities encountered on computed tomography (CT) imaging during preoperative preparation for unilateral cochlear implant placement in an adult male with profound sensorineural hearing loss (SNHL). Methods: A rare case of bilateral bifid intratemporal facial nerves in an adult male is presented. The finding's impact on approach to safe cochlear implantation is discussed. Results: Bifurcation of the intratemporal facial nerve is rarely seen and is usually associated with congenital middle or inner ear anomalies. A unique case of bilateral bifid intratemporal facial nerves without other middle or inner ear abnormalities was encountered incidentally on CT imaging during preparation for unilateral cochlear implant placement in an adult male with profound SNHL. The nerve was bifid along the mastoid segment with a nerve branch traversing through the facial recess precluding safe traditional approach to cochlear implant placement. Accessory stylomastoid foramina were noted bilaterally. Unilateral subtotal petrosectomy was performed with successful implantation and excellent hearing outcome. No additional clinical or radiographic otologic abnormalities were noted. Conclusion: Abnormal bifurcation of the facial nerve may occur in adults without other middle or inner ear anomalies. This case highlights the importance of independent imaging review by the surgeon and vigilance to potential rare anatomic aberrations of the facial nerve during cochlear implantation.
