Summary
Retaining the lingual plate during impacted wisdom tooth removal significantly reduces lingual nerve sensory loss. This surgical technique offers optimal protection for the lingual nerve, minimizing complications like transient paresthesia.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Anesthesiology
Background:
- The lingual nerve is vulnerable during mandibular third molar extraction.
- Lingual nerve injury can lead to persistent sensory deficits.
Purpose of the Study:
- To evaluate the incidence of lingual nerve sensory loss after impacted mandibular third molar removal.
- To determine the protective effect of retaining the lingual plate on the lingual nerve.
Main Methods:
- A prospective study involving 362 patients undergoing 504 impacted wisdom tooth removals.
- Surgical technique involved the retention of the lingual plate.
- Data collected on tooth eruption status, bone removal, tooth division, and postoperative complications.
Main Results:
- Only one patient (0.2%) experienced transient paresthesia, which resolved within a month.
- The majority of teeth (76%) were partially erupted, and most (76%) required tooth division.
- Bone removal was necessary in 99% of cases.
Conclusions:
- Retention of the lingual plate is an effective method for protecting the lingual nerve during impacted mandibular third molar surgery.
- This technique minimizes the risk of lingual nerve injury and associated sensory disturbances.
