Mandibular incisive canal in relation to periapical surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Neuroanatomy
• Dental Pathology

Background:

• The mandibular interforaminal neurovascular bundle is crucial for sensation in the lower lip and chin.
• Oral and maxillofacial surgeries in the anterior mandible carry a risk of injury to this bundle.
• Awareness and careful surgical technique are essential to prevent neurovascular complications.

Observation:

• A 58-year-old male presented with left lower lip pain and tingling.
• Radiographic and clinical examinations revealed a cyst associated with periapical pathology and a missing tooth.
• Surgical enucleation of the cyst was performed.

Findings:

• The cyst cavity was found to be in close proximity to the mandibular incisive nerve.
• Post-operative documentation confirmed the anatomical relationship between the cyst and the nerve.

Implications:

• This case underscores the critical importance of identifying and preserving the mandibular incisive nerve during anterior mandibular procedures.
• Surgeons and dentists should exercise caution during cyst enucleations, implant placements, and other surgeries in this region.
• Enhanced anatomical knowledge and meticulous surgical planning can mitigate the risk of iatrogenic nerve injury and associated sensory disturbances.
