Tilley Lichtwitz Antrum Trocar 1.80mm, 5Fg

Clinical Application

Provides minimally invasive access to the maxillary antrum for procedures that require controlled puncture and immediate fluid management. Common applications include drainage and aspiration of infected or mucoid contents, irrigation of the sinus cavity, diagnostic aspiration, and delivery of topical medications. The small 1.80 mm (5Fg) profile is suitable when a low-profile entry is required to minimize mucosal disruption.

Design & Configuration

The instrument uses a cannula-and-obturator (trocar) arrangement to allow precise puncture of the antral wall followed by secure cannulation for fluid exchange. The slim diameter reduces tissue trauma during transnasal or percutaneous entry and facilitates placement through narrow nasal passages. The obturator provides controlled penetration while the cannula maintains a patent channel for suction, irrigation, or instillation without repeated passages.
