Prichard Periosteal Elevator: A Sensitive but Essential Surgical Tool for Reflection of Tissue

In the highly challenging field of surgery, particularly in fields like periodontics, oral and maxillofacial surgery, and plastic surgery, the ability to delicately and gently lift and retract the periosteum is generally most important in order to expose more internal bone structures. The Prichard periosteal elevator, a small surgical tool, is a delicate but necessary surgical instrument for accomplishing this critical step with minimal trauma.

Understanding the Design of the Prichard Periosteal Elevator

The Prichard periosteal elevator can be described as having a double-ended, elongated shape. Its most recognizable feature is that it can be used on different anatomical contours and tissue thickness. Its usual features are:

Double-Ended Style: Both sides of the Prichard elevator consist of an unusual shape and length blade. A generally wider, flatter blade on one side and a thinner, pointed or gently curved blade on the other side. Both sides have widespread elevation as well as more specific elevation in closer regions.

Thin and Sharp Blades: Prichard elevator blades are thin and only typically sharp enough. This is because they are so easy to push beneath the periosteum and slide the tissue off the bone easily and precisely without tearing or excessive force.

Angled Shanks: The shanks between the handle and blades are generally angled. These provide improved access and visibility to the operative field, especially in the posterior or hard-to-reach area of the oral cavity or facial skeleton.

Ergonomic Handle: The handle is often designed to provide a firm and comfortable grip to allow for fine control and delicate handling of the instrument for procedures that are delicate in nature.

The Central Role in Periosteal Reflection

Periosteum is a fibrous sheath covering the outer surface of bones. Its accurate reflection and retraction are essential in the majority of surgical interventions for several reasons:

Bone access: The periosteal elevation provides the surgeon with an open, unobstructed view of the underlying bone so that bone grafting, implantation, osseous recontouring, or cyst enucleation can be performed.

Periosteal surfaces will have fundamental vessels supplying the underlying bone with fundamental nutrition. Techniques of reflection of low aggressivity using a reflection instrument very much like that of the Prichard elevator are available for facilitating the continuing blood supply and hence the stimulated healing and growth of the bone.

Atraumatic Displacement of the Periosteum: Prichard's blades are thin, fine, and extremely sharp, and the least traumatic reflection that prevents tissue injury, operating discomfort, and avenues for postoperative complication.

Flap Management: In surgical procedures in tissue flaps, Prichard's elevator facilitates easier elevation and positioning of flaps delicately without damaging them or disrupting their blood supply.

Applications Across Surgical Specialties

Prichard periosteal elevator is an excellent tool in most fields of surgery:

Periodontics: It is used extensively in periodontal flap surgery to reflect the periosteum and overlying gingival soft tissues to allow access to the alveolar bone to carry out procedures like scaling and root planing, bone grafting, and guided tissue regeneration. Its delicate structure enables it to address the often lacking access in periodontal surgery.

Oral and Maxillofacial Surgery: The Prichard elevator is utilized for a monstrous variety of oral surgical procedures like flap elevation in tooth extractions (most prominently impacted teeth), pre-prosthetic surgery, and short bone grafting procedures.

Plastic and Reconstructive Surgery: In facial reconstructive and some cosmetic bone surgery, the Prichard elevator offers firm periosteal elevation in the exposure and molding of inner bone anatomy.

The Importance of Gentle Precision

The Prichard periosteal elevator testifies to the science of surgery as one of gentle care. Its atraumatic handling of tissues is maximized without sacrificing the leverage that is sufficient enough to efficiently reflect the periosteum. Its two-ended shape maximizes its use too, and it is a surgeon's favorite tool for surgeons requiring fine control and minimal tissue trauma in exposing the underlying bone. With a qualified surgeon, Prichard periosteal elevator is a most important surgical instrument to achieve reproducible and successful surgery.
