Overview
- The lingual nerve is a branch of the mandibular (V3) division of the trigeminal nerve
- Provides sensation to the anterior two-thirds of the tongue, the floor of the mouth, and the lingual mucous membrane
- Lingual nerve block is an effective means of anesthesia for tongue lacerations and avoids the anesthesia of the lip, chin, and teeth that inferior alveolar nerve block causes[1]
- No chance of accidental carotid artery puncture compared to IANB
- Studies have shown lower rates of nerve injury and trismus compared to IANB as well as greater success rates[2]
Indications
- Tongue laceration
- Sublingual abscess drainage
- Foreign body removal
- Sialolith removal
- Periodontal surgery
- Glossodynia
Contraindications
- Lingual soft tissue infection
- Local anesthetic allergy
Equipment Needed
- Gloves
- Aseptic mouth rinse
- 4x4 gauze
- Suction
- Syringe
- 25-27 gauge needle
- Topical anesthetic
- Local anesthetic
Procedure[3]
- Have the patient rinse their mouth with an aseptic mouth rinse.
- Apply soaked gauze with topical anesthetic.
- Place patient reclining or upright and have them open their mouth.
- Identify site of injection: 1 cm medial to the second mandibular molar.
- Have the patient move their tongue to the side or use a tongue blade.
- From the contralateral side, approach with your needle and insert 1 cm posteriorly directed.
- Aspirate to confirm location is not intravascular.
- Inject 1.0 - 1.5 ml local anesthetic.
Complications
- Hematoma
- Infection
- Failure to anesthetize
