The Evolving Landscape of Spatial Hearing Assessment and Rehabilitation in Iran: A Review of Behavioral, Electrophysiological, and Clinical Translation Gaps
摘要
To systematically review the current status of spatial hearing assessment and rehabilitation in Iran, focusing on integrating advanced behavioral and electrophysiological methodologies and identifying critical gaps in clinical translation for audiological and otological patient management. A comprehensive search covered international (PubMed/MEDLINE, Scopus, Web of Science) and Iranian repositories (SID, Magiran) for studies published from January 2005 through December 2025. Search terms included (“Spatial Hearing” OR “Sound Localization”) AND (“Iran” OR “Iranian”) AND (“Assessment” OR “Rehabilitation”. Inclusion criteria focused on original research, case reports, and reviews concerning spatial hearing assessments (e.g., localization tasks, Minimum Audible Angle) or spatial hearing rehabilitation in Iranian cohorts. Data synthesis used descriptive statistics and qualitative analysis for clinical translation barriers. Literature is nascent, mainly addressing basic sound localization in normative populations. Electrophysiological assessments are confined to research. Clinical application of advanced batteries (e.g., spatial release from masking, Persian-adapted questionnaires) is sparse. Significant gaps remain in standardized electrophysiological screening and validated Persian-language outcome measures. A substantial disparity exists between research capabilities and routine clinical implementation in Iranian audiology/otology. Bridging this gap requires standardized protocols, specialized testing environments (sound field setups), and validation of context-specific outcome measures.
