One academic year laboratory and student breathing zone formaldehyde level, measured by gas-piston hand pump at gross anatomy laboratory, Siriraj Hospital, Thailand.

This study used a formaldehyde detector tube with a gas-piston hand pump to assess ceiling levels of student breathing zone and gross laboratory environment across the 2018 academic year. The room dimension was 28.6 × 55.

Dimensional guide to harvesting the radius for orofacial reconstruction.

Objective: To provide an accurate harvesting guide to maintain the maximum possible safe dimensions of the radius for orofacial reconstruction using the osteocutaneous radial forearm free flap.

Material And Method: Two hundred radii of 100 adult formalin-embalmed cadavers (52 males, 48 females) were measured.

Results: The mean minimum circumference of the radius measured between the pronator teres and brachioradialis insertions was 41.
