Neivert-Anderson Straight 20 cm — Mastoid Bone-Cortex

Otto Neivert (re-used here for ENT angled-pattern) and Anderson collaborated on the angled-raspatory family. The 20 cm Neivert-Anderson straight is the mastoid-bone cortex tier — straight-shaft mastoid-cortex periosteal-elevation prior to powered-drill use during cortical-mastoidectomy for chronic-suppurative-otitis-media CSOM, mastoid-tip apex periosteal-stripping during para-styloid surgical-approach for skull-base lesion, and Lempert-flap creation during fenestration-of-lateral-semicircular-canal for selected otosclerosis-revision after stapedectomy-failure. Neivert-And straight 20.

Mastoid-straight use

• Cortical-mastoid pre-drill CSOM
• Mastoid-tip apex para-styloid SB
• Lempert-flap fenestration LSCC otoscler-rev
