# Managing Oral Surgery Cases

Structures oral surgery case documentation with extraction complexity assessment, surgical planning, intraoperative documentation, complication management, and post-operative monitoring per AAOMS guidelines.

## Why This Skill Exists

Oral surgery carries the highest complication rate and malpractice exposure of any routine dental procedure. Third molar extractions alone account for a disproportionate share of dental malpractice claims, primarily from nerve injury (IAN and lingual nerve), displaced roots into the maxillary sinus or submandibular space, and failure to manage post-operative complications (alveolar osteitis, hemorrhage, infection). This skill enforces pre-surgical risk assessment, standardized complexity grading, step-by-step operative documentation, and complication monitoring to reduce adverse outcomes and ensure defensible records.

## Checkpoint A — Pre-Surgical Verification

### Required Inputs
- Current panoramic radiograph or periapical of the surgical site; CBCT when indicated (proximity to IAN, displaced roots, complex anatomy)
- Complete medical history with attention to: anticoagulants (warfarin INR, DOACs), antiplatelet agents, bisphosphonate/denosumab use (MRONJ risk), diabetes status, immunosuppression, radiation history to head/neck
- Current medication list with dose and frequency
- Blood pressure and pulse recorded pre-operatively
- Signed surgical consent form detailing risks specific to the procedure
- ASA physical status classification documented
- Antibiotic prophylaxis determination (AHA guidelines for cardiac conditions; AAOMS guidelines for immunocompromised patients)

### Intake Questions
1. What is the indication for surgery (caries, periodontal disease, orthodontic, pathology, prophylactic third molar removal)?
2. Is the patient taking anticoagulants or antiplatelets, and has the prescribing physician been consulted about perioperative management?
3. Has the patient taken bisphosphonates or denosumab (oral or IV), and for what duration?
4. Does the patient have a history of difficult extractions, prolonged bleeding, or poor wound healing?
5. Has the patient had radiation to the head and neck region (osteoradionecrosis risk)?
6. Is the patient aware of specific risks including nerve injury, sinus communication, jaw fracture, and dry socket?
7. Who is the responsible driver/escort for patients receiving sedation?

## Step 1 — Extraction Complexity Assessment

Grade surgical difficulty before beginning the procedure.

- **Simple extraction (D7140)**: Tooth erupted, intact crown, single or convergent roots, adequate bone support for forceps delivery, no pathology complicating extraction
- **Surgical extraction with soft tissue flap (D7210)**: Requires mucoperiosteal flap elevation; tooth partially erupted, root tips only remaining, or bone removal required for delivery
- **Surgical extraction with bone removal (D7220/D7230)**: Impacted tooth requiring flap, bone removal, and possible sectioning; classify impaction depth (soft tissue, partial bony, full bony) and angulation (mesioangular, distoangular, horizontal, vertical)
- **Third molar complexity factors**: Proximity to IAN canal (< 2 mm on panoramic or CBCT contact), root morphology (curved, hooked, dilacerated, hypercementosed), relationship to second molar and ramus, depth of impaction (Pell-Gregory classification: Class I/II/III, Position A/B/C), Winter classification for angulation
- **Risk factors elevating complexity**: Age > 35, ankylosis, root resorption, proximity to maxillary sinus floor, prior radiation, osteoporosis

---

## Step 2 — Surgical Planning

Document the planned approach before starting.

- **Anesthesia plan**: Type (local only, local with oral sedation, IV sedation, general anesthesia); block and infiltration technique
- **Incision design**: Envelope flap, triangular flap, or modified approach; planned incision location relative to tooth and adjacent structures
- **Bone removal plan**: Anticipated extent of buccal bone removal; bur type (handpiece at 35,000 rpm with copious irrigation vs. piezoelectric surgery)
- **Sectioning plan**: For impacted molars — crown-root separation, furcation split, or root sectioning; document planned cut lines
- **Nerve management**: If IAN or lingual nerve is at risk, document planned approach to minimize injury (coronectomy consideration, intentional staged extraction, nerve lateralization referral)
- **Sinus precautions**: For maxillary posterior teeth, document proximity to sinus floor and planned approach if perforation occurs

---

## Step 3 — Intraoperative Documentation

Record the surgical procedure in detail.

- **Anesthesia delivered**: Type, concentration, vasoconstrictor, volume, injection sites, aspiration results
- **Incision and flap**: Actual incision design, location, and extent of flap elevation
- **Bone removal**: Extent, instrument used, irrigation method and volume
- **Tooth delivery**: Forceps/elevator technique, sectioning performed (describe cut lines), root tip retrieval method if fractured
- **Socket assessment**: Inspection for residual root fragments, granulation tissue curettage, buccal plate integrity, sinus membrane integrity (Valsalva test for maxillary posterior)
- **Complications encountered**: Root tip fracture (retained vs. retrieved), oro-antral communication (size, repair method — primary closure, buccal advancement flap, collagen plug), nerve paresthesia noted (test lip/tongue sensation before dismissal), excessive hemorrhage (management method), alveolar fracture
- **Grafting (if performed)**: Material type, manufacturer, lot number (per FDA tracking), membrane if used, fixation method
- **Closure**: Suture material (chromic gut, Vicryl, silk), size, pattern (simple interrupted, figure-8, mattress), number of sutures placed

---

## Step 4 — Sinus Communication Management

If oro-antral communication is created during maxillary extraction, follow AAOMS protocol.

- **Detection**: Valsalva test (patient exhales through nose while nostrils are pinched; bubbling through socket = positive), direct visual inspection, probe test
- **Small communication (< 2 mm)**: Blood clot formation may be sufficient; place collagen plug, figure-8 suture, and sinus precautions
- **Moderate communication (2–5 mm)**: Primary closure with buccal advancement flap; collagen membrane or resorbable barrier
- **Large communication (> 5 mm)**: Buccal fat pad flap or palatal rotation flap; consider referral to oral surgeon if beyond comfort level
- **Post-communication protocol**: Sinus precautions (no nose blowing, no straw use, no smoking, sneeze with mouth open) for 2 weeks; decongestant (pseudoephedrine) and antibiotic (amoxicillin + clavulanate or clindamycin if allergic) for 7–10 days
- **Documentation**: Size of communication, repair method, materials used, post-op instructions specific to sinus communication, follow-up plan

---

## Step 5 — Post-Operative Management and Complications

Document post-operative care and monitor for complications.

- **Immediate post-op**: Gauze pressure for 30–45 minutes, ice packs 20 minutes on/off, written post-operative instructions provided
- **Pain management**: Multimodal approach — ibuprofen 400–600 mg q6h alternating with acetaminophen 500–1000 mg q6h; opioids only for breakthrough pain; document rationale per state PDMP requirements
- **Alveolar osteitis (dry socket)**: Onset day 3–5 post-extraction; severe throbbing pain, exposed bone in socket, foul taste; treat with gentle irrigation and medicated dressing (eugenol-based or iodoform); change dressing every 2–3 days until symptoms resolve
- **Post-operative infection**: Fever, increasing swelling > 48 hours, purulent drainage, trismus; culture and sensitivity when possible; empiric antibiotic coverage (amoxicillin or clindamycin); assess for fascial space involvement requiring I&D
- **Hemorrhage**: Immediate post-op — additional pressure, gelatin sponge, topical thrombin, suturing; delayed hemorrhage — evaluate for anticoagulant complication or systemic coagulopathy
- **Nerve injury assessment**: Test light touch, two-point discrimination, and directional sensation for IAN (lower lip, chin) and lingual nerve (anterior 2/3 tongue); document findings at each follow-up; refer if no improvement at 3 months

## Guidelines

- Never document an extraction as simply "tooth extracted without complication" — record the technique, instruments, and delivery method
- Assess and document IAN proximity for all mandibular third molars; if radiographic signs of proximity are present (root darkening, narrowing, deflection, interruption of canal), recommend CBCT before extraction
- Bisphosphonate patients require MRONJ risk assessment before any extraction; document drug name, route (oral vs. IV), duration of therapy, and discussion of MRONJ risk with patient per AAOMS Position Paper
- For anticoagulant patients, document the perioperative management decision (continue therapy with local hemostatic measures vs. hold medication with physician consultation) and clinical rationale
- Coronectomy is a legitimate alternative to complete extraction for lower third molars with intimate IAN contact — document the decision rationale and follow-up plan for root monitoring
- All extracted tissue sent for pathologic examination when pathology is suspected; document specimen submission and receiving laboratory
- Dry socket occurs in 2–5% of routine extractions and 25–30% of mandibular third molar extractions — proactive patient education about risk factors (smoking, oral contraceptives, traumatic extraction) is a documentation requirement
- Post-operative nerve injury must be documented at each follow-up with standardized sensory testing; refer to oral surgery or neurology if no recovery by 3 months
