The Sigmoid Notch Retractor is a 22 cm oral and maxillofacial instrument designed to engage the mandibular notch during orthognathic and ramus surgery. Handcrafted from German stainless steel with a 9.5 mm / 16 mm concave blade and a fully bent tip ($64), it protects the masseteric nerve and vessels while stabilizing ramus osteotomies.
Product Description
The Sigmoid Notch Retractor is a specialized oral and maxillofacial surgical retractor engineered specifically to provide safe, non-traumatic soft-tissue displacement and osseous stabilization along the mandibular notch during ramus osteotomies. Designed to hook over the superior concavity between the coronoid process and the mandibular condyle, this instrument allows surgeons to perform vertical ramus or sagittal split procedures while completely shielding deep neurovascular structures from reciprocating saws.
Built to provide the perfect balance between clinical reach and manual control, this Sigmoid Notch Retractor configuration features an overall tool length of 22 cm ($64). Handcrafted from premium operating room-grade German stainless steel to ensure lasting strength and corrosion resistance, the working blade profile incorporates a 9.5 mm / 16 mm concave blade layout featuring a fully bent tip geometry that seats securely into the sigmoid notch cortex without slipping. The ergonomic flat handle provides operating assistants with steady manual leverage, preventing hand fatigue during prolonged midface and mandibular reconstructions.
Forged with an anti-glare satin matte finish, Retractor Maker manufactures the Sigmoid Notch Retractor to withstand high-frequency autoclave sterilization protocols while offering a lifetime warranty against rust and defects, providing oral, maxillofacial, and facial reconstructive surgical teams worldwide with exceptional structural resilience, corrosion resistance, and complete autoclave durability.

Frequently Asked Questions
What are the blade and handle design advantages of the Sigmoid Notch Retractor?
The Sigmoid Notch Retractor is a solid one-piece instrument, so its performance comes from blade geometry and handle ergonomics. The working blade is specified as 9.5 mm / 16 mm concave blade layout featuring a fully bent tip geometry, which spreads retraction force over a wider contact area and reduces point pressure on tissue. The handle is ergonomic flat handle with lateral serrations for tactile grip stability, giving a secure, fatigue-resistant grip through long exposures. An overall length of 22 cm (approx. 8.7 inches) keeps the surgeon's hand clear of the operative field. It is made from premium operating room-grade german stainless steel (aisi 304/420) for glare-free, corrosion-resistant service.
What is the Sigmoid Notch Retractor used for?
The Sigmoid Notch Retractor is used in maxillofacial surgery to hook into the mandibular sigmoid notch, retracting the masseter muscle and shielding the masseteric nerve and vessels during ramus osteotomies.
Which surgical procedures is it for?
It is indicated for intraoral vertical ramus osteotomy (IVRO), sagittal split ramus osteotomy (SSRO), inverted L osteotomy, coronoidectomy, and temporomandibular joint (TMJ) reconstruction.
What material and finish are used?
The instrument is handcrafted from premium German surgical stainless steel with an anti-glare satin matte finish that eliminates optical reflections under surgical operating lights and headlights.
