[Distraction osteogenesis in the head and neck region]

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials Engineering

Context:

• Distraction osteogenesis is a vital technique in oral and maxillofacial surgery.
• It enables significant jaw lengthening or repositioning beyond conventional osteotomy limits.
• This method facilitates gradual bone separation, stimulating new bone formation.

Purpose:

• To describe the principles and applications of distraction osteogenesis in oral and maxillofacial surgery.
• To compare the use and implications of extraoral and intraoral distractors.
• To highlight potential airway complications and management strategies associated with distractors.

Summary:

• Distraction osteogenesis involves the slow separation of osteotomized bone segments, allowing for new bone regeneration in the gap.
• Extraoral distractors offer ease of fitting and removal, while intraoral distractors avoid external scarring and daily burdens.
• Potential airway obstruction by distractors necessitates careful anesthetic management, including laryngoscopy, and consideration of alternatives like fibroscopic intubation or tracheotomy.

Impact:

• Enhances surgical options for correcting severe jaw discrepancies and deformities.
• Provides a method for achieving bone augmentation not possible with standard surgical procedures.
• Improves patient outcomes by enabling complex reconstructions and functional improvements in the maxillofacial region.
