Obwegeser Pterygoid Osteotome, 10mm Wide, 23.5cm — Overview

The Obwegeser Pterygoid Osteotome (S27-155-23) is a 23.5cm, 10mm-wide osteotome designed specifically to complete the pterygomaxillary disjunction — the separation of the maxilla from the pterygoid plates of the sphenoid bone — one of the final and most critical bone cuts in Le Fort I osteotomy.

Why the Pterygoid Cut Is Critical

The maxilla is anchored posteriorly to the pterygoid plates, and this connection must be cleanly separated before the maxilla can be fully mobilized during Le Fort I surgery. This cut is performed in a deep, poorly visualized location close to major vascular structures, making a purpose-built, appropriately sized and shaped osteotome essential for controlled, safe separation at this specific and technically demanding step.

23.5cm Length, 10mm Width

The substantial 23.5cm length gives the surgeon the reach needed to access this deep, posterior surgical location, while the 10mm width is calibrated specifically for the pterygomaxillary disjunction cut.

Clinical Use

This osteotome is used specifically in Le Fort I osteotomy for the pterygomaxillary disjunction, a defined and critical step within the Obwegeser orthognathic surgical sequence.

Material and Construction

Manufactured from surgical-grade stainless steel and hand-finished in Sialkot, Pakistan, with a hardened, precisely ground cutting edge.

Sterilization and Care

Fully autoclavable. The cutting edge should be inspected before each use for nicks or dulling, given the precision and safety margin this specific step requires.
