The long face syndrome: vertical maxillary excess
American Journal of Orthodontics
|October 1, 1976
Summary
Long face syndrome, a distinct facial morphology, is characterized by excessive maxillary vertical growth. This dentofacial deformity presents as dental open or closed bites, with increased mandibular height in closed-bite cases.
Area of Science:
- Dentofacial Orthopedics
- Craniofacial Biology
- Orthodontics
Background:
- Long face syndrome (LFS) is a clinically recognized facial morphology.
- Previous literature has incompletely described LFS.
- This study analyzes LFS in adults.
Purpose of the Study:
- To analyze the esthetics, skeletal morphology, and occlusion in adults with LFS.
- To confirm the underlying dentofacial deformity in LFS.
- To identify variations within LFS, specifically dental open and closed bites.
Main Methods:
- Clinical summary analysis of thirty-one adult patients diagnosed with LFS.
- Evaluation of facial esthetics.
- Assessment of skeletal morphology and occlusion.
Main Results:
- Confirmed excessive vertical growth of the maxilla as the primary dentofacial deformity in LFS.
- Identified dental open bite and closed bite as two variants of the syndrome.
- Found an increased mandibular ramus height specifically in the closed-bite variant of LFS.
Conclusions:
- LFS is characterized by excessive maxillary vertical overgrowth.
- Dental open and closed bites are distinct presentations of LFS.
- Mandibular ramus morphology differentiates subtypes of LFS, impacting treatment strategies.
