Asymmetrical bilateral double mandibular canals: anatomicoradiological study and clinical implications

Area of Science:

• Anatomy
• Radiology
• Oral Surgery

Background:

• Accessory mandibular foramina are rare anatomical variations.
• Their presence can impact surgical procedures and radiological interpretations.
• Detailed documentation is essential for clinical practice.

Purpose of the Study:

• To provide a comprehensive morphological and radiological description of bilateral accessory mandibular foramina.
• To highlight the clinical significance of these anatomical variants for various medical specialties.

Main Methods:

• Morphological examination of an adult human mandible.
• Radiological assessment of the mandibular canals and foramina.
• Detailed description of the location and characteristics of accessory foramina.

Main Results:

• Bilateral accessory mandibular foramina were identified.
• The right side showed an accessory foramen superior to the main mandibular foramen.
• The left side presented a mandibular foramen divided by bony septa, creating two foramina.
• Both accessory foramina led to asymmetrical mandibular canals.

Conclusions:

• Accessory mandibular foramina represent significant anatomical variations.
• Accurate identification is vital for nerve block techniques, radiation therapy planning, and dental implant/reconstructive surgery.
• This study enhances the understanding of mandibular osteological variations for improved clinical accuracy.
