Area of Science:

  • Ophthalmology
  • Oral and Maxillofacial Surgery
  • Medical Technology

Background:

  • Orbital osteotomy traditionally carries risks of injury to the eyeball and soft tissues.
  • Piezoelectric technology has demonstrated enhanced safety in oral and maxillofacial surgery.

Purpose of the Study:

  • To evaluate the novel application of piezoelectric technology in various orbital surgeries.
  • To assess the safety and efficacy of piezoelectric saws for orbital osteotomy.

Main Methods:

  • An interventional case series reviewed 16 patients undergoing 18 orbital surgeries using a piezoelectric blade across three institutions.
  • Data collected included surgical indication, patient demographics, follow-up duration, complications, and outcomes.

Main Results:

  • The piezoelectric system was used for orbital decompression, lateral orbitotomy, cranio-orbitotomy, and dacryocystorhinostomy.
  • All osteotomies were narrow and smooth, with surgeons noting superior precision and safety compared to traditional saws.
  • No intraoperative complications or soft tissue lacerations occurred; postoperative healing was uneventful.

Conclusions:

  • The piezoelectric saw blade provides a safer and more precise alternative for orbital osteotomy due to its ability to cut narrow troughs without damaging soft tissues.
  • This technology enhances surgical outcomes and reduces the risk of complications in orbital procedures.
