Glossary Entry: Orthognathic Surgery

Overview

Definition: Orthognathic surgery is a type of surgery performed to correct irregularities in the jawbones and realign the jaws for improved function and facial appearance in patients with severe bite or jaw alignment issues.

Detailed Description

Types and Variations

Variations: Different types of orthognathic surgeries include maxillary osteotomy, mandibular osteotomy, and genioplasty, each addressing specific jaw realignment needs.

Indications

Common Uses: Orthognathic surgery is commonly used to treat conditions such as overbite, underbite, crossbite, facial asymmetry, and obstructive sleep apnea related to skeletal issues.

Insertion and Placement

Procedure: The surgery involves carefully cutting and repositioning the jawbones to achieve proper alignment and bite function, often using techniques like the Seldinger technique for precise placement.

Clinical Considerations

Potential Complications

Risks: Potential complications of orthognathic surgery include infection, nerve damage, blood loss, and temporary numbness or swelling in the face.

Care and Maintenance

Maintenance Requirements: Patients need to follow post-operative care instructions, including a soft diet, good oral hygiene, and attending follow-up appointments, to ensure proper healing and long-term results.

Additional Information

Related Devices

Associated Terms: Jaw wiring, braces, and splints are common accessories used in combination with orthognathic surgery to aid in the realignment process.

Innovations and Advancements

Recent Developments: Recent advancements in orthognathic surgery include computer-assisted planning for more accurate surgical outcomes and virtual surgical simulations for better treatment planning.

Regulatory and Safety Notes

Regulations: Orthognathic surgery requires thorough pre-operative evaluations, careful surgical planning, and adherence to safety guidelines to minimize risks and ensure successful outcomes.
