Maxillary hypoplasia was treated using skeletal anchorage for maxillary protraction, successfully correcting facial and occlusal discrepancies. Pterygomaxillary separation did not enhance orthopedic outcomes in this case.
Area of Science:
- Orthodontics
- Craniofacial Surgery
Background:
- Maxillary hypoplasia and tooth agenesis present complex challenges in pediatric treatment.
- Maxillary protraction with skeletal anchorage is a modern approach to correct midface deficiency.
Observation:
- A 7-year-old girl with maxillary hypoplasia and multiple tooth agenesis underwent treatment.
- Skeletal anchorage using mini-plates in the nasal cavity facilitated maxillary protraction with a reverse-pull facemask.
- Pterygomaxillary separation was performed concurrently to augment protraction effects.
Findings:
- Skeletal anchorage effectively corrected maxillomandibular discrepancy, improving facial aesthetics and occlusion without adverse dental effects.
- Pterygomaxillary separation showed no significant benefit in enhancing maxillary advancement or restricting growth during the 12-month follow-up.
Implications:
- Skeletal anchorage offers a reliable method for correcting maxillary hypoplasia in pediatric patients.
- Further research is needed to evaluate the efficacy of pterygomaxillary separation in conjunction with maxillary protraction.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
