The Omni-Tract in Head&Neck Surgery: A Universal Retractor Adaptable for Remote Cervical Approaches

Published Nov 24, 2025

Updated Apr 30, 2026

In recent years, interest in remote access approaches to the neck has expanded significantly within the field of H&N Surgery, and particularly in H&N Robotic Surgery. The shift toward less visible incisions, hidden scars, and more ergonomic anatomical access has encouraged the adoption of new instruments as well as the creative adaptation of existing ones.

Although dedicated retractors for gas-less remote access approaches exist, they are not widely available in all Centers and, depending on the region of the world, may not be accessible at all.

This has led surgeons to reconsider other options—among them, universal table-mounted retractors.

Retractor Systems: A Brief Historical Overview

As abdominal surgery evolved alongside the advent of sterile techniques, surgeons quickly recognized the need for devices to “retract” tissues and organs to create a functional working space. The earliest retractors were handheld and appeared in the late 1800s.

A major breakthrough came with the development of self-retaining retractors, beginning with the Doyen retractor (1885). These systems could be mounted on the operating table or supported by the edges of the surgical wound. Many table-mounted designs appeared throughout the 20th century. Among those still commonly used today are:

• Thompson Retractor – Richard C. Thompson, 1965
• Bookwalter Retractor – John Bookwalter, 1981
• Omni-Tract Retractor System – Samuel Penta, 1990

This article focuses on the latter, as it is one of the few systems that can be adapted effectively for remote-access neck surgery, and the one we do have experience with.

What Is the Omni-Tract?

The Omni-Tract is a rigid, stable, and highly modular table-mounted retraction system widely used in general surgery, colorectal surgery, and hepatopancreatobiliary procedures. Its main advantages include:

• A universal, fully configurable system compatible with multiple arms, blades, and mounting options
• Excellent mechanical stability, ideal for deep surgical fields
• The ability to create asymmetric or anatomically tailored configurations
• Low relative cost and broad availability in most hospitals

Although not originally designed for remote cervical approaches, its versatility has made it a practical alternative when dedicated neck retractors are not available.

Retroauricular Approach Using the Omni-Tract

The Omni-Tract possesses the essential characteristics required for retroauricular access to the neck:

• It allows the creation of a stable working tunnel from the retroauricular incision to the cervical region.
• It provides secure fixation of long, narrow blades suitable for deep dissections.
• It accommodates lateral patient positioning commonly used for retroauricular approaches.
• Its modularity helps recreate the triangular working geometry needed for remote-access dissection.

Experience accumulated across multiple centers demonstrates that progress in remote-access surgery does not always depend on acquiring new technologies. Innovation often begins with rediscovering and adapting tools already available in the operating room.

Set-up

The system is designed for rapid assembly and high configurability.

For the retroauricular approach, the goal is to position a long, relatively narrow blade in a near-horizontal position to provide “tent-like” exposure of the working space. The assembly sequence is as follows (see the components bellow):

1. The Omni-Tract components are fully sterilizable; therefore, assembly occurs within the sterile field.
2. The field post (A) is anchored to the side rail of the operating table. Its upper end contains the locking mechanism for the first horizontal arm.
3. The one-piece support arm (B) is attached and secured in the desired position using its lever-based locking system.
4. This one-piece support arm is designed to support two symmetrical wishshbone frame arms (C), originally intended for abdominal incisions. For the retroauricular approach, only one short wishbone frame arm—on the operative side—is required.
5. A side-snatch clamp (D) is mounted on the wishbone frame arm.
6. The selected retractor blade (E) is then attached. Several blades in the Omni-Tract catalogue are well suited to cervical access.

The system provides enough degrees of freedom to position the blade precisely while maintaining stability comparable to that of other self-retaining retractors used in robotic neck surgery, such as the FKWO or LARS mounted on articulated arms.

Thinking of Starting Remote Access Surgery but Lacking a Dedicated Retractor?

Ask your general surgeons or urologists—there is probably an Omni-Tract somewhere in your hospital.
