Subperiosteal Hematoma of the Orbit

Spontaneous intracranial extradural haematoma associated with frontal sinusitis and orbital involvement

“…Once the dural vessels adjacent to the infected region become inflamed, the vessel walls may weaken and it may become prone to bleeding even after a subclinical trauma [10], such as barotrauma by coughing and sneezing during an asthmatic crisis as occurred in our patient. Orbital hematomas are classified by Landa [23] either as subperiostal or intraorbital. Subperiosteal hematomas are most often post-traumatic, associated with an adjacent orbital fracture [23][24][25][26][27]; however, it can occur after surgery around the orbit and in patients with sinusitis [28].…”

“…Orbital hematomas are classified by Landa [23] either as subperiostal or intraorbital. Subperiosteal hematomas are most often post-traumatic, associated with an adjacent orbital fracture [23][24][25][26][27]; however, it can occur after surgery around the orbit and in patients with sinusitis [28]. In the latest cases, the presence of bony defect secondary to erosion following chronic infection produces the vascular congestion with increased intravascular pressure resulting in the hematoma formation [24,26,27].…”

Posttraumatic subperiosteal orbital hematoma

“…However, SOH should be distinguished from a blow out fracture as well as from other space occupying conditions such as orbital emphysema and retrobulbar hematoma. The main differences between SOH and retrobulbar hematoma are the absence of significant lid hematoma and the absence of rapid and progressive visual loss in SOH, although in a posteriorly located SOH some degree of visual impairment might be present (Palimar and McIlwaine, 1995;Landa et al, 1998;Key et al, 2008).…”

“…Despite this, the true incidence of SOH is still unknown since there is no systematic study of its occurrence in patients with midfacial trauma. SOH does not require urgent surgical intervention and therefore the reported treatment options vary from a conservative approach (Katz and Carmody, 1985;Geyer et al, 1990;Palimar and McIlwaine, 1995), needle aspiration (Brucoli et al, 2005) and surgical evacuation and drainage (Leopold et al, 1980;Zalzal, 1991;Landa et al, 1998;Choi et al, 2004). Although there are no reported complications related to any of above mentioned treatments, it is reasonable to presume that inadequate evacuation of hematoma could result in infection, fibrous organisation, cystic formation or calcification.…”

Traumatic bilateral intraorbital (subperiosteal) hematoma associated with epidural hematoma: case report

“…Most of these diseases can be excluded based on the history, physical and radiological examination. Chronic hematic intraorbital cysts may result from undiagnosed or untreated intraorbital hematomas [1][2][3][4][5] .…”
