• The most common complication following sinus trauma is sinusitis, usually resulting from edema, blood, retained bone or
soft-tissue fragments, or foreign bodies.
• Craniofacial trauma accounts for approximately 28% of mucoceles.
• Mucoceles can present decades after the inciting trauma, so life-long follow up is indicated.
• Foreign bodies of the paranasal sinuses are associated with trauma in 70% of cases, and most commonly involve the maxillary
sinus. Thorough and complete debridement in the acute setting is essential to prevent long-term complications.
• Paranasal sinus epidermoids have been reported to occur following traumatic implantation of squamous mucosa.
• Management of paranasal sinus epidermoids involves ventilation of the affected sinuses with longterm endoscopic follow up.
• Traumatic aneurysms of the internal carotid artery can present as an isolated sinus mass.
