Among them, four completed the 6\u2010month follow\u2010up and are presented in detail. While Case 1 was previously reported, this analysis includes all four to explore ACT's broader application. The intervention targeted ACT's six core processes. Outcomes were measured using the Tinnitus Handicap Inventory (THI), Cognitive Fusion Questionnaire\u20107 (CFQ\u20107), Valuing Questionnaire (VQ), and Hospital Anxiety and Depression Scale (HADS). After 6 months, three patients showed a clinically meaningful THI reduction. Those without hearing loss improved more in CFQ\u20107 and HADS. VQ scores showed minimal change.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ACT may
