From the Guidelines
The treatment of a blowout fracture of the inferior wall of the left orbit typically involves both conservative management and possible surgical intervention, with surgical repair indicated if there is persistent diplopia beyond 2 weeks, significant enophthalmos (>2mm), or muscle entrapment causing restricted eye movement, as recommended by the most recent guidelines 1. The initial management includes prescribing oral antibiotics such as amoxicillin-clavulanate 875/125 mg twice daily for 7-10 days to prevent infection, along with decongestants like pseudoephedrine 60 mg every 6 hours for 5-7 days to reduce sinus pressure. Pain management with acetaminophen or NSAIDs is also recommended. Patients should avoid nose blowing, sneezing with an open mouth, and strenuous activity for 2-3 weeks to prevent increased orbital pressure. Cold compresses can be applied for the first 48 hours to reduce swelling.
Key Considerations for Surgical Intervention
- Persistent diplopia beyond 2 weeks
- Significant enophthalmos (>2mm)
- Muscle entrapment causing restricted eye movement The timing of surgery is typically within 2 weeks of injury, with earlier intervention for muscle entrapment, as suggested by the guidelines 1. Surgery involves repositioning orbital contents and placing an implant to reconstruct the orbital floor. This approach balances the need to allow spontaneous resolution of symptoms while preventing long-term complications like persistent double vision or cosmetic deformity from orbital tissue herniation into the maxillary sinus.
Additional Considerations
- Orbital fat entrapment can prove nearly as challenging as extraocular muscle entrapment, resulting in fibrotic and adhesion syndromes not readily relieved with dissection around the involved muscle, as noted in a recent study 1.
- Adhesions and entrapment may extend well into the deeper orbit, out of reach of the strabismus surgeon.
- Preoperative forced generation testing and preoperative and intraoperative forced duction testing are very important, as emphasized in the guidelines 1.
From the Research
Treatment Options for Blowout Fracture of the Inferior Wall of the Left Orbit
The treatment for a blowout fracture of the inferior wall of the left orbit may involve surgical intervention or conservative management, depending on the severity of the fracture and the presence of symptoms such as debilitating double vision and globe malposition 2.
Surgical Intervention
Surgical intervention may be necessary to restore orbital anatomy and function, and to prevent long-term sequelae 2. The surgical approach may involve the use of novel techniques and materials, such as titanium mesh, to reconstruct the orbital floor 3. The endoscopic transconjunctival and transcaruncular approach is a useful and promising technique to repair combined medial and inferior orbital wall fractures 4.
Conservative Management
Conservative management may be appropriate for patients with minimal symptoms and no evidence of complications, such as enophthalmos or diplopia 5. A watchful waiting period may be recommended to allow for the subsidence of edema and to determine the need for surgical intervention 6.
Timing of Treatment
The timing of treatment is crucial, and patients who are admitted to a tertiary care facility within 48 hours of the injury may have a lower rate of complications 5. Early recognition of the injury and timely surgical intervention may prevent long-term disability and improve patient outcomes 2, 5.
Key Considerations
- Thorough evaluation and timely surgical intervention may prevent long-term sequelae 2
- Novel surgical techniques and materials may optimize patient outcomes 2, 3
- Conservative management may be appropriate for patients with minimal symptoms 5, 6
- Timing of treatment is crucial, and early intervention may improve patient outcomes 5
