Comparison of Blood Loss and Time Requirement in Bilateral Sagittal split osteotomies (BSSO) Procedures: Piezoelectric Handpiece vs. Conventional Rotary Handpiece- A retrospective Study

Abstract

Bilateral Sagittal Split Osteotomy (BSSO) is a widely utilized surgical procedure in orthognathic surgery, primarily aimed at correcting mandibular deformities such as prognathism, retrognathism, and asymmetry. The procedure involves splitting the mandibular ramus bilaterally, allowing for the repositioning of the lower jaw to achieve proper occlusion and facial symmetry. BSSO is favored for its ability to maintain a stable and predictable outcome, while also allowing for rigid fixation of the bone segments. Despite its advantages, BSSO is technically demanding and requires meticulous surgical planning and execution to avoid complications such as nerve injury, unfavorable fractures, and excessive blood loss. Advances in surgical instruments, including the introduction of piezoelectric devices, have enhanced the precision of the osteotomies, potentially reducing intraoperative complications. This abstract provides an overview of the indications, technique, and outcomes of BSSO, emphasizing its role in contemporary orthognathic surgery and the ongoing developments aimed at improving its safety and efficacy
