Traumatic Orbital Compression Syndromes: A Comprehensive Study Into Etiologies, Intervention Strategies, and Clinical Outcomes.

Facial fractures and their historical link to potential blindness have been well-documented, often attributed to optic canal injuries or retinal vascular occlusion. This dire consequence can result from both direct and indirect ocular trauma, including retrobulbar hemorrhage. Traumatic orbital compression can manifest in various forms, such as hematomas, fractured bone fragments, and emphysema, all posing a significant threat to vision, necessitating immediate intervention.

Cytotoxicity evaluation of Chlorhexidine and Blue®M applied to a human gingival fibroblast (HGF-1) and keratinocytes (NOK-SI): In vitro study.

Chlorhexidine (CHX) is a prime choice to control the oral microbiota. However, it's a chemical agent leading to side effects such as teeth strains, taste disturbance, and desquamation of oral mucosa. Alternatively, the lactoferrin and oxygen-based Blue®M has been introduced as an alternative to the CHX, not disturbing tissue repair.
