Blood flow changes after sagittal split of the mandibular ramus

Summary
Blood flow to the mandible decreases after sagittal split surgery, but increases in chewing muscles. Careful surgical technique is recommended for correcting mandibular anomalies.
Area of Science:
- Oral and Maxillofacial Surgery
- Craniofacial Anatomy
- Surgical Physiology
Background:
- The sagittal split osteotomy is a common surgical procedure for correcting mandibular deformities.
- Understanding the impact of this procedure on regional blood flow is crucial for optimizing surgical outcomes and patient recovery.
Purpose of the Study:
- To investigate the changes in blood flow to various cephalic tissues following unilateral sagittal split osteotomy in macaque monkeys.
- To identify specific anatomical regions affected by altered blood perfusion after the surgical procedure.
Main Methods:
- Utilized the microsphere method to quantify blood flow in different cephalic tissues.
- Measurements were taken before and after unilateral sagittal split of the mandible in a macaque monkey model.
Main Results:
- Observed significant decreases in blood flow within specific bony regions of the osteotomized mandible.
- Demonstrated a significant increase in blood flow to the masseter and medial pterygoid muscles on the side of the osteotomy.
Conclusions:
- Surgical manipulation during sagittal split osteotomy affects regional blood flow in the mandible and associated musculature.
- Judicious consideration of mucoperiosteum stripping and the pterygomasseteric sling is important for surgical planning in mandibular anomaly correction.
