Oral Surgery

Definition

Oral Surgery refers to any medical procedure performed in the oral cavity or on the jaws to treat a variety of conditions, defects, or injuries. While it is a recognized specialty (see Oral and Maxillofacial Surgery), many "minor" oral surgeries are performed by general practitioners in a clinical setting.

The primary goal of oral surgery is to restore function, alleviate pain, or resolve pathological conditions that cannot be managed through non-surgical means.

Common Procedures

1. Dentoalveolar Surgery

The most frequent category of oral surgery, involving the teeth and their supporting bone.

Tooth Extraction: The removal of a tooth from its socket in the alveolar process.
Surgical Extraction: Required when a tooth is not easily accessible (e.g., broken at the gum line) and requires a soft tissue flap and bone removal.
Impacted teeth: Most commonly involving the third molars (wisdom teeth) that fail to erupt properly.

2. Preprosthetic Surgery

Surgical preparation of the mouth before the placement of dentures or other prostheses.

Alveoloplasty: Reshaping and smoothing the jawbone after extractions.
Tori Removal: The surgical reduction of bony outgrowths (tori) that interfere with denture fit.
Frenectomy: The removal of a "frenum" (fold of tissue) that may be causing a gap between teeth or interfering with tongue movement.

3. Biopsy and Pathology Management

When an abnormal lesion is found during a stomatological exam, oral surgery is required to obtain a definitive diagnosis.

Incisional Biopsy: Removing a small piece of a large lesion.
Excisional Biopsy: Removing the entire lesion (often used for small growths like fibromas).

4. Periradicular Surgery

Surgical procedures related to the root of the tooth, often performed when Endodontic Therapy fails.

Apicoectomy: The removal of the root tip and the surrounding infected tissue.

Surgical Principles

Success in oral surgery relies on several fundamental principles:

Asepsis: Maintaining a sterile or highly clean environment to prevent post-operative infection.
Hemostasis: Controlling bleeding during and after the procedure through pressure, suturing, or hemostatic agents.
Flap Design: Creating surgical incisions that preserve the blood supply to the soft tissue and allow for proper healing.
Suturing: The use of stitches (resorbable or non-resorbable) to close wounds and promote primary intention healing.

Anesthesia and Sedation

Oral surgery requires effective pain management. Depending on the complexity and patient anxiety, options include:

Local Anesthesia: Numbing a specific area (e.g., IANB for the mandible).
Nitrous Oxide: "Laughing gas" for mild sedation.
Intravenous Sedation: Inducing a state of deep relaxation while the patient remains conscious.

Post-Operative Complications

Alveolar Osteitis (Dry Socket): Loss of the blood clot in an extraction site, leading to exposed bone and severe pain.
Paresthesia: Numbness or tingling caused by nerve trauma (often the Inferior Alveolar Nerve).
Trismus: "Lockjaw" or limited opening of the mouth due to muscle inflammation.
