dingman body ostectomy

- involves a section of the lower jaw's body being surgically removed to correct deformities like a jaw that sticks out too far.

- often performed using a transoral (intraoral) approach, aims to preserve the inferior alveolar nerve, which is freed and mobilized before the bone is cut and the segments are repositioned and secured.

- done through a single-stage or two-stage approach, with the latter involving both intraoral and extraoral components.

subapical osteotomy

- cut and reposition the bone segment containing the anterior teeth (the anterior alveolar segment) of the upper or lower jaw.

- used to correct dental and jaw alignment issues, such as protruding or receding teeth,

- can be performed as an isolated surgery or as part of a larger orthognathic (jaw) surgery.

- involves cutting the bone both horizontally and vertically, repositioning the tooth-bearing segment, and securing it with plates and screws.

vertical ramus osteotomy

- cuts the mandibular (lower jaw) ramus vertically to allow for repositioning of the jaw for orthognathic surgery, which corrects facial deformities.

- used to treat conditions like mandibular prognathism and hemifacial microsomia, and is sometimes called intraoral vertical ramus osteotomy (IVRO) if performed inside the mouth

sagittal split ramus osteotomy

- used in orthognathic surgery to correct jaw deformities by splitting the lower jawbone (mandible) in a sagittal plane and repositioning the tooth-bearing segment.

- This is typically done to move the lower jaw forward or backward,

- often a part of a bilateral procedure (BSSO) used to treat conditions like mandibular prognathism.

- Post-surgery recovery often involves swelling, numbness, and a soft diet for several weeks
