Study Summary

This trial is testing whether using platelet-rich fibrin (PRF) or proximal segment grooving (PSG) can help with nerve recovery after sagittal split osteotomy (SSO).

Who is the study for?
This trial is for adults with dentofacial deformities or obstructive sleep apnea who are undergoing a jaw surgery called bilateral sagittal split osteotomy (BSSO). It's not for those who've had previous jaw surgeries, existing nerve issues in the face, trouble understanding the consent process, or conditions that affect healing like being on certain medications.Check my eligibility
What is being tested?
The study tests if platelet-rich fibrin (PRF), grooving of the bone near the nerve during surgery (PSG), or both can help nerves recover after BSSO. Patients will be randomly assigned to one of four groups: PRF and PSG, just PRF, just PSG, or neither. Nerve function recovery will be tracked for up to a year.See study design
What are the potential side effects?
Potential side effects may include discomfort at the site where blood is drawn to make PRF and possible additional risks from modifying surgical techniques such as increased bleeding or infection.
