Lingual nerve (LN) injury is common during dental procedures. This study precisely maps the LN
Area of Science:
- Anatomy
- Oral Surgery
- Head and Neck Surgery
Background:
- Lingual nerve (LN) injuries are a known complication in dental and maxillofacial procedures.
- Despite its known course, precise anatomical landmarks for the LN are crucial for prevention.
Purpose of the Study:
- To accurately predict the lingual nerve pathway using measurable anatomical landmarks.
- To reduce the incidence of lingual nerve injury during surgical interventions.
Main Methods:
- Dissection of the lingual nerve was performed on 28 cadaveric hemimandibles.
- Measurements were taken relative to the alveolar crest and mandibular second molar.
Main Results:
- The lingual nerve was located approximately 7 mm below the alveolar crest at the distal mandibular second molar.
- Measurements confirmed its proximity to the lingula and the mylohyoid muscle attachment.
Conclusions:
- The lingual nerve is at high risk of injury due to various head and neck procedures.
- This study provides precise anatomical data to aid surgeons in avoiding lingual nerve damage.
