Summary
Endoscopic surgery effectively treats delayed orbital blowout fractures. Persistent double vision (diplopia) in these cases is primarily caused by adhesions, which this endoscopic approach can resolve.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
- Trauma Surgery
Background:
- Orbital blowout fractures are common injuries.
- Delayed treatment can lead to persistent diplopia.
- Endoscopic techniques offer minimally invasive surgical options.
Purpose of the Study:
- Evaluate endoscopic reduction surgery for delayed orbital blowout fractures.
- Identify the cause of persistent diplopia in delayed cases.
- Assess the effectiveness of endoscopic surgery in resolving diplopia.
Main Methods:
- Retrospective study of 114 patients with isolated blowout fractures (1997-2006).
- Focus on 6 delayed cases (over 3 months post-trauma) with persistent diplopia.
- Endoscopic endonasal approach for surgical reduction.
Main Results:
- Remarkable adhesion between periorbita and sinus mucosa noted in delayed cases.
- Successful dissection of adhesions and removal of bone fragments.
- Intraoperative eye traction tests confirmed ocular motility improvement.
- Diplopia resolved postoperatively in five out of six patients.
Conclusions:
- Endoscopic reduction surgery is a viable treatment for delayed orbital blowout fractures.
- Adhesion formation is the primary cause of persistent diplopia in delayed cases.
- Endoscopic surgery effectively addresses these adhesions, improving outcomes.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:26Flail Chest-II
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
