The etiologic role of frontal sinusitis in pediatric orbital abscesses

Intracranial Complications of Ethmoiditis Evidenced by Magnetic Resonance Imaging

“…A series of 6 children with orbital abscesses has been presented. 12 Those with frontal sinusitis developed abscesses in the superolateral location, as shown here. In addition to thrombophlebitis and septic microemboli, it was suggested that direct extension through congenital bony dehiscences posterior to the trochlear fossa at the supraorbital notch and at the junction of the middle and outer thirds of the frontal sinus floor, would explain the preponderance in this location.…”

Microbiology of Subperiosteal Orbital Abscess and Associated Maxillary Sinusitis

“…Studies that separately investigated the microbiology of SPOA 4‐6 and sinusitis 7 found the microbiology to be most of the time monomicrobial, and occasionally polymicrobial due to aerobic and anaerobic bacteria of oral flora origin. Some studies did not specify whether the origin of the organism(s) was the sinus or SPOA 8‐10 .…”

“…Some studies did not specify whether the origin of the organism(s) was the sinus or SPOA 8‐10 . However, the role of anaerobic bacteria in SPOA was not well studied in most past reports, as methods for their recovery were inadequate or were not consistently utilized 4,5,7‐10 . The unique microbiology of sinusitis associated with SPOA and the correlation between the organisms at both sites has not been studied before and was not reported separately before.…”

Visual Loss Reversed After Treatment of Acute Bacterial Sinusitis

“…The radiographic study of choice for the orbital complications of ABS is CT scan with contrast medium 10 . Magnetic resonance imaging studies are indicated if there is suspicion of intracranial spread; 11 otherwise, magnetic resonance imaging is considered inferior to CT scan for assessment of bony erosion and orbital infection.…”
