Mandibular canal versus inferior alveolar canal: A Delphi study

Area of Science:

• Anatomical Terminology
• Neurovascular Anatomy
• Oral and Maxillofacial Surgery

Background:

• The "mandibular canal" is a key anatomical structure in the mandible.
• Current terminology may not accurately reflect the canal's contents, the inferior alveolar neurovascular bundles.
• Discrepancies in terminology can affect communication and understanding among medical professionals.

Purpose of the Study:

• To evaluate the current understanding and usage of terminology for the mandibular canal.
• To determine the most appropriate name for the bony canal housing the inferior alveolar neurovascular bundles.
• To assess expert opinions across various geographical regions and specialties.

Main Methods:

• A Delphi study methodology was employed.
• A panel of 52 experts from diverse fields (anatomy, oral surgery, radiology, dentistry, plastic surgery, ENT) participated.
• Participants responded to email questionnaires regarding terminology for the mandibular canal.

Main Results:

• Experts in anatomy, oral/OMF surgery, and ENT/plastic surgery favored "mandibular canal."
• Experts in oral/OMF radiology and dentistry showed a preference for "either mandibular canal or inferior alveolar canal."
• General principles of anatomical terminology support "inferior alveolar canal."

Conclusions:

• The study suggests "inferior alveolar canal" as a more appropriate and descriptive term.
• Adopting standardized terminology enhances clarity in anatomical and clinical contexts.
• Further consensus may be needed, but evidence points towards a name change.
