Rethinking Sudden Sensorineural Hearing Loss: Emerging Evidence and a New Surgical Approach (MiTT-PLF-S
Ahmet Atas, Tetsuo Ikezono

Sudden sensorineural hearing loss (SSNHL) continues to present major diagnostic and therapeutic challenges, despite decades of research. While most current guidelines focus on empirical treatments such as systemic or intratympanic steroids, recent advances in diagnostics have raised fundamental questions about overlooked causes—especially Perilymphatic Fistula (PLF).

This keynote lecture will introduce a paradigm shift in the way we understand and treat SSNHL, with a focus on the following key topics:

  • An overview of recent evidence from clinical trials involving steroids, antivirals, and regenerative therapies

  • The emerging role of biomarkers and imaging in identifying subgroups and predicting prognosis

  • Re-examining PLF as a real and often unrecognized etiology of SSNHL

  • Introduction of MiTT-PLF-S: a newly developed minimally invasive trans-tympanic PLF repair technique using fibrin glue, with clinical data and case outcomes

  • Notably, MiTT-PLF-S has shown hearing improvement even in patients beyond the traditional 28-day treatment window, suggesting its potential value for delayed cases

  • Discussion on how endotype-based approaches can enhance early intervention and precision treatment in SSNHL

  • Insights gained from over 1,500 cases of Cochlin-tomoprotein (CTP) testing, which has been officially Japanese FDA approved and reimbursed as a diagnostic tool in Japan. These nationwide results have helped shape current clinical strategies and deepen understanding of PLF-related hearing loss.
