Hartmann Trocar 2mm — Otologic Cavity Drainage

Hartmann Trocar — 2mm Otologic Cavity Drainage

The 2mm Hartmann trocar (Arthur Hartmann’s Berlin otology tradition, covered for the ENT instrument family earlier) is the finest variant in the Hartmann trocar-cannula range — used for chronic-suppurative-otitis-media cavity drainage, mastoid-cavity inspection, and the percutaneous trans-canal procedures that some otologic teaching centres preserve. The 2mm bore is at the smallest practical scale for trocar-cannula equipment.

The mastoid-cavity-drainage indication

Mastoid cavities (created by mastoidectomy or by long-standing chronic suppurative otitis media with auto-mastoidectomy) accumulate debris and infection over time. Periodic cavity inspection, debridement, and irrigation are part of routine post-operative care at otologic centres. The 2mm Hartmann trocar provides percutaneous access for the cavity drainage component when standard otoscopy is inadequate.

The Berlin-school otology tradition

Arthur Hartmann’s Berlin Charité otology practice defined late-nineteenth-century European otology; his trocar-cannula designs were part of the comprehensive instrument set that propagated with his trainees worldwide. The trocar variants remain in production for traditional otologic-instrument trays.
