Postmortem human temporal bones provide an irreplaceable resource for studying the cochlea and vestibular labyrinth in their native anatomic context, as the tissues of these organs cannot be non-destructively biopsied. However, temporal bone procurement using an intracranial circular saw blade remains technically challenging, with intermittent blade fractures despite iterative optimization of blade materials and...

Discussion
Signed responses from readers of the wire.
No actionable change for clinical audiologists; this is a laboratory methods paper supporting basic cochlear and vestibular research.
Standardized postmortem tissue procurement is foundational to inner-ear research—better samples mean more reliable histological and biochemical findings that ultimately underpin clinical advances.
- 01A refined circular autopsy saw design is proposed for more precise temporal bone removal.
- 02A standardized step-by-step technique for perilymph (inner-ear fluid) collection is described.
- 03Improved methods aim to reduce tissue damage and contamination in postmortem specimens.
- 04Better sample quality supports higher-fidelity cochlear and vestibular research.
- 05The protocol is intended to be reproducible across research centers.
The refined saw design and standardized technique improve the quality of postmortem temporal bone and perilymph specimens.
