Macroscopic and microscopic findings following thulium laser exposure

Group	Peak temperature (°C)	Charring depth (µm)	Histology (H&E, 40x)
Dry	28 ± 2	0	Intact, uniform fibres
Water-soaked	32 ± 3	0	Intact, uniform fibres
Blood-soaked	65 ± 5	250 ±50	Superficial carbonisation, deeper structures intact on H&E but not formally characterised
