Open reduction in trapdoor-type blowout fractures using absorbable mesh plates

Area of Science:

• Ophthalmology
• Plastic Surgery
• Maxillofacial Surgery

Background:

• Orbital blowout fractures, particularly trapdoor type, present unique challenges in reconstruction.
• Traditional methods often involve alloplastic implants or bone grafts, which can lead to complications.

Observation:

• A retrospective study evaluated 34 patients with trapdoor orbital blowout fractures treated between 2008 and 2010.
• Surgical approaches included subciliary, transconjunctival, and transcaruncular methods under general anesthesia.

Findings:

• Internal fixation using an absorbable mesh plate successfully reduced and stabilized displaced bony segments.
• Postoperative evaluations confirmed accurate anatomical reconstruction with no eye movement limitations or surgical complications.
• Follow-up CT scans validated the precise reconstruction of the orbital wall.

Implications:

• Internal fixation offers an advantageous alternative for trapdoor orbital blowout fractures, preserving native bone and sinus mucoperiosteum.
• The technique promotes rapid healing, maintains sinus function, and simplifies the surgical procedure.
• This method represents a preferred treatment option, minimizing the need for grafts or implants and reducing surgery-related complications.
