Maxillary 3rd Molar Extraction

Maxillary 3rd Molar Extraction

Open Dropdown

Preoperative Considerations

Consent:

  • Infection
  • Bleeding
  • Loss of tooth or root fragment into maxillary sinus or infratemporal space requiring possible re-operation
  • Oroantral fistula possibly requiring secondary procedure to repair

Anesthesia/Positioning:

  • Reclined (Clinic)
  • Supine (OR)

Other:

  • None

Armamentarium:

  • Minnesota
  • Throat pack
  • 15 blade
  • Periosteal elevator
  • Straight elevator
  • Back action elevator (E77RPN)
  • 150 forcep
  • Rongeur
  • Needle driver, tissue pick up, DeBakey, 3-0 chromic gut (optional)

Technique

Place Minnesota retractor distal to maxillary 3rd molar
If needed (soft tissue or full bony impacted), use a #15 blade to create a sulcular incision with a distobuccal release. Use #9 to create a full thickness mucoperiosteal flap. Place Minnesota within the flap ensuring the tooth does not get dislodged into the infratmporal space.
Use a #9 to release the soft tissues
Use a #9 to release the soft tissue attachments
Use a straight elevato or a back action to mobilize the tooth
Before proceeding with th extraction pace a throat pack to prevent aspiration
Use a 150 or Rongeur forcep to extract the tooth with gentle buccal / lingual pressure
Ensure tooth and roots are intact

Postoperative Considerations

Immediate:

  • Bite down gently on gauze for 1 hour post op
  • Avoid straws, spitting for 1 week post op
  • Cough with mouth open for 1-2 weeks post op
  • If bleeding persists after 1 hour post op, bite down on gauze gently for 1 more hour post op w gentle and consistent pressure

Follow Up:

  • FU is not mandatory in most cases
  • If needed can check soft tissues for healing and any signs of infection or oroantral fistula

Imaging:

Panoramic radiograph with impacted/malpositioned#1,16,17,32. Remaining exam grossly within normal limits.

Assessment/ Plan:

‍  with impacted/malpositioned#1,16,17,32

Plan:

- Recommend extraction. Discussed option of retaining teeth with periodic monitoring. Using radiograph as a visual aid, I reviewed the risks of removal including but not limited to pain, swelling, bleeding, infection, temporary/permanent neurosensory deficit of lower lip/chin/teeth/gums/tongue including dysesthesia, retained root tips, damage to adjacent teeth, oroantral communication/fistula, alveolar osteitis, jaw fracture, periodontal defect, TM pain/trismus, need for additional procedures. Usual recuperation discussed, as well. Anesthesia options reviewed including local anesthesia alone or with either nitrous oxide or IV sedation. Reviewed risks of sedation including but not limited to recall, PONV, respiratory or cardiovascular compromise, allergic reactions, need for additional interventions. All questions answered.

 

- Shared decision to proceed with extraction of #1,16,17,32 under local anesthesia & IV sedation

Procedure Note

Pre-operative Diagnosis:

impacted/malpositioned#1,16,17,32

Post-operative Diagnosis:

same as above

Procedure Performed:

Extraction of #1,16,17,32

Anesthesia:

Local anesthesia & IV Sedation

Procedure in Detail:

Consent reviewed after discussing benefits/risks/alternatives with patient and/or family member and inviting all questions. H&P and imaging reviewed. Pre procedure vitals noted to be within a safe range. A surgical timeout was performed with patient participation in order to confirm patient, procedure, and laterality. 

NPO/escort verified. All appropriate monitors were placed and working properly. IV started with 22 ga catheter. Sedative medications were then administered and titrated to effect per anesthesia record. 

4% septocaine w/ 1:100k epi  x 4 carpules administered via local infiltration and 2% Lido w/ 1:100k epi x 4 carpules administered via bilateral PSA, IAN, lingual nerve blocks. Adequate anesthesia confirmed. Attention directed at tooth #1, where a sulcular incision with a distobuccal release was made, followed by subperiosteal reflection. The tooth was then extracted using elevators without complication, site was irrigated with normal saline. Attention was then directed at tooth #32, where a sulcular incision with a distobuccal release was made, followed by subperiosteal reflection and removal of buccal bone using a fissure bur in surgical handpiece. The tooth was then sectioned and removed with elevators and forceps. Site was irrigated with normal saline and flap was reapproximated. Attention was then directed at tooth #16, where a sulcular incision with a distobuccal release was made, followed by subperiosteal reflection. The tooth was then extracted using elevators without complication, site was irrigated with normal saline. Attention was then directed at tooth #17, where a sulcular incision with a distobuccal release was made, followed by subperiosteal reflection and removal of buccal bone using fissure bur in surgical handpiece. The tooth was then sectioned and removed with elevators and forceps. The site was copiously irrigated with normal saline and flap was reapproximated. Collagen plugs placed into all extraction sites. Bilateral gauze packs placed, hemostasis noted.

Monitored recovery without incident. Vital signs and mental status at baseline

Patient discharged in stable condition with verbal & written postoperative instructions.

Rx: 

Amoxicillin, percocet, ibuprofen

Return to Clinic:

1 week for post-op eval if needed
