Perioperative Management and Anesthesia
Perioperative management and anesthesia in oral and maxillofacial surgery is the body of knowledge concerned with rendering surgical procedures of the mouth, jaws, and face painless and safe, across a continuum that runs from local anesthesia in the dental chair to deep sedation and general anesthesia in the operating room. It integrates pharmacology, airway physiology, patient assessment, monitoring, and pain control before, during, and after the operation.
Definition
Perioperative anesthesia management is the planning and delivery of anesthesia, sedation, monitoring, and analgesia spanning the pre-, intra-, and postoperative phases of an oral or maxillofacial procedure, calibrated to the patient and the operation so that the procedure can be performed comfortably and safely.
Scope
This area orients the reader to how anesthesia and perioperative care are organized in oral and maxillofacial surgery. It groups the essentials into local anesthetic technique and pharmacology, conscious (moderate) sedation and monitoring, general anesthesia for surgical procedures, airway management and the prevention of complications, and postoperative pain management. It is a reference overview of methods and principles, not a manual for delivering anesthesia or a source of dosing or treatment instructions.
Sub-topics
Core questions
- What depth of anesthesia or sedation is appropriate for a given patient and procedure?
- How are the airway and vital functions protected when the same anatomical field is shared by surgeon and anesthetist?
- How is pain controlled during and after surgery while minimizing drug-related harm?
Key concepts
- Continuum of depth of sedation and anesthesia
- Shared airway in oral and maxillofacial surgery
- Preoperative risk assessment
- Physiologic monitoring
- Local anesthesia and regional nerve blocks
- Multimodal analgesia
- Office-based versus operating-room anesthesia
Mechanisms
Anesthetic care in this field rests on a small set of physiologic levers. Local anesthetics reversibly block voltage-gated sodium channels in peripheral nerves to interrupt pain conduction; sedatives and general anesthetics act on central nervous system targets to produce graded reductions in awareness and responsiveness along a continuum (Becker & Reed, 2012; Brown et al., 2010). Because the surgical field and the airway overlap, maintaining ventilation and oxygenation is a continuous concern, and depth of sedation, airway patency, and hemodynamics are tracked with structured monitoring (asa-sedation-2018). Pain after surgery is addressed by combining agents and techniques that act at different points of the pain pathway, an approach described as multimodal analgesia (Chou et al., 2016).
Clinical relevance
Perioperative anesthesia knowledge underlies the safe conduct of procedures ranging from third-molar removal to orthognathic and reconstructive surgery, much of which is performed in office-based settings unique to oral and maxillofacial surgery (Lieblich, 2020). This entry describes the principles and methods of that care for orientation and is not a basis for selecting agents, doses, or anesthetic plans for an individual patient.
Evidence & guidelines
The field is shaped by interdisciplinary practice guidelines, including the American Society of Anesthesiologists guidelines on moderate procedural sedation (asa-sedation-2018) and on management of the difficult airway (asa-airway-2022), and multisociety guidance on postoperative pain management (Chou et al., 2016). These documents synthesize evidence and expert consensus and are periodically updated.
History
Pain control for oral procedures advanced rapidly after the mid-nineteenth-century introduction of inhalational general anesthesia in dentistry and surgery and the subsequent development of injectable local anesthetics. Over the twentieth century the discipline added structured patient assessment, physiologic monitoring, and a graded approach to sedation, while oral and maxillofacial surgery developed a distinctive tradition of office-based anesthesia delivered by the operating surgeon or a dedicated anesthesia provider.

Frequently asked questions
- What does perioperative mean in this context?
- It refers to the entire period surrounding an operation - before (preoperative assessment and planning), during (intraoperative anesthesia and monitoring), and after (postoperative recovery and pain control).
- Why is anesthesia in oral and maxillofacial surgery considered distinctive?
- Because the surgical site and the airway share the same anatomical region, and because much care is delivered in office settings, the field places particular emphasis on airway protection, monitoring, and a graded continuum of sedation and anesthesia.
