Lateral Mandibulotomy

ūüĎČA lateral mandibulotomy has several disadvantages:

  • First, the muscular pull on the two segments of the mandible is unequal:
    • Putting the mandibulotomy site under significant stress and causing a delay in healing:
      • For this reason, intermaxillary fixation may be required.
  • Second, the ability to gain access to the suture line to maintain cleanliness following surgery in the oral cavity is hampered as a result of intermaxillary fixation:
    • Leading to poor oral hygiene and the potential risk for sepsis of the suture line.
  • In addition, a lateral mandibulotomy poses several anatomic disadvantages:
    • Leading to denervation of the teeth distal to the mandibulotomy site and the skin of the chin:
      • As a result of transection of the inferior alveolar nerve.
  • A lateral mandibulotomy also causes devascularization of the distal teeth and the distal segment of the mandible:
    • From its endosteal blood supply.
  • The exposure provided by a lateral mandibulotomy is limited.
  • If the patient needs postoperative radiation therapy:
    • The mandibulotomy site is directly within the lateral portal of radiation therapy:
      • Leading to delayed healing and complications at the site of the mandibulotomy.

ūüĎČFor these reasons, a lateral mandibulotomy is not recommended.
