Residual diplopia in treated orbital bone fractures

Area of Science:

• Ophthalmology
• Plastic Surgery
• Trauma Surgery

Background:

• Residual diplopia (RD) is a primary complication following orbital bone fracture (OBF) reduction.
• Causes of RD are multifactorial, including inflammation, surgical timing, graft use, and trauma to orbital structures.

Purpose of the Study:

• To investigate the prevalence and influencing factors of residual diplopia after orbital bone fracture repair.
• To identify key factors affecting surgical outcomes in corrective procedures for RD.

Main Methods:

• Retrospective study of 69 patients undergoing OBF reduction and corrective surgery (2000-2011).
• Analysis of patient demographics, fracture characteristics, treatment details, and graft types.
• Statistical analysis using SPSS, including descriptive statistics and Chi-square tests (P ≤ 0.05 significance).

Main Results:

• Inferior rectus muscle entrapment (71%) and other periorbital musculature issues (56.5%) were primary causes of RD.
• Globe position abnormalities occurred in 52.1% of cases.
• Degree of inflammation and graft types showed significant correlation with RD (P = 0.000).

Conclusions:

• Preoperative swelling, muscle inflammation, and graft selection significantly influence surgical success in OBF.
• RD is directly linked to these factors, emphasizing the need for controlled OBF healing and remodeling.
• Modified surgical techniques using mesh and cartilage offer effective solutions for secondary corrective surgery in RD.
