Surgical correction of vertical maxillary excess: a re-evaluation

Area of Science:

• Oral and Maxillofacial Surgery
• Orthognathic Surgery
• Craniofacial Surgery

Background:

• Vertical maxillary excess correction often involves Le Fort I osteotomy.
• The downfracture technique is prevalent, but total maxillary alveolar osteotomy remains an alternative.
• Long-term stability of maxillary intrusion is crucial for successful outcomes.

Observation:

• Two patients treated with total maxillary alveolar osteotomy were re-evaluated.
• The study reviews literature on maxillary stability after intrusion via Le Fort I osteotomy and ostectomy combinations.
• The downfracture method's advantages are discussed.

Findings:

• The long-term stability of maxillary intrusion following total maxillary alveolar osteotomy requires careful consideration.
• The downfracture method offers specific advantages in maxillary intrusion.
• An alternative technique promoting intimate bone contact is presented.

Implications:

• Understanding the long-term stability of different maxillary intrusion techniques is vital for surgical planning.
• The findings may influence the choice of surgical method for correcting vertical maxillary excess.
• Further research into alternative techniques ensuring bone stability is warranted.
