Politzer/Buck Ear Knife (Myringotome) 15.5cm

Clinical Application

Designed for controlled myringotomy incisions, this instrument is used to create a small, precise opening in the tympanic membrane to evacuate middle-ear effusion, obtain diagnostic samples, or facilitate insertion of tympanostomy tubes. Commonly employed in otology procedures for pediatric and adult patients with otitis media with effusion, barotrauma, or persistent middle-ear fluid, it is used under microscopic or loupe magnification and in conjunction with suction and tympanostomy tube instruments.

Design & Configuration

The slender, rigid shaft and scalpel-style myringotomy tip provide tactile feedback and fine control for shallow, precise incisions of the tympanic membrane. The length supports comfortable reach and handling in the constrained ear canal while permitting one-handed manipulation alongside suction or tube placement instruments. The cutting geometry is intended to minimize tissue trauma and facilitate predictable entry into the middle ear space.
