Abstract
BackgroundOrbital cellulitis is an ophthalmic emergency, which is associated with vision-threatening adverse effects. The purpose of this study is investigating etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis.MethodA retrospective medical record and radiologic file review of patients with infectious orbital cellulitis was performed to detect all patients with non-medial orbital cellulitis who referred to Khalili hospital from 2016 to 2019. Age, sex, origin of infection, size of collection or abscess, medical or surgical management, microbiology, first and final best-corrected visual acuity, duration of admission, and complications was recorded. Patients divided into two groups; medical management and surgical management groups and all of data compared between in this groups.ResultsOf ninety-six patients with infectious orbital cellulitis, 23 cases (14 male, 9 female) were included. Five patients (21.7%) were managed medically and 18 patients (78.3%) were managed surgically. Patients’ age range was 5–70 years old. Most common location for non-medial cellulitis was superior space (66.7% in surgical and 40% in medical group; p = 0.511). In 13 cases of surgical group (72.3%) were detected microorganisms. The mean ± SD of collection volume in medical group were 476.5 ± 290.93 mm3 and 2572.94 ± 1075.75 mm3 in surgical group (p < 0.001). Ten patients in surgical group had compressive optic neuropathy. The mean ± SD of collection volume was 3204.97 ± 879.88 mm3 in patient with compressive optic neuropathy and 1280.43 ± 880.68 mm3 in patient without compressive optic neuropathy (P < 0.001). One case complicated by subdural empyema and another case progressed to necrotizing fasciitis.ConclusionNon-medial orbital cellulitis is an uncommon but sight-threatening and life-threatening condition. Timely diagnosis and accurate management reduce morbidity and mortality. Combined surgery for patients with superior or supra-temporal and large non-medial abscess is recommended.
Highlights
Periorbital Infections based on the involvement of structures and soft tissues, anterior or posterior to the orbital septum anatomically are divided into; preseptal cellulitis and orbital cellulitis [1, 2]
One case complicated by subdural empyema and another case progressed to necrotizing fasciitis
We retrospectively reviewed the medical records and radiologic files computed-tomography (CT) scan and/or Magnetic resonance imaging (MRI)) of all patients who were admitted with a diagnosis of orbital cellulitis at Khalili hospital, Shiraz, Iran, from August 2016 to January 2019
Summary
Periorbital Infections based on the involvement of structures and soft tissues, anterior or posterior to the orbital septum anatomically are divided into; preseptal cellulitis (occurs anterior to the septum) and orbital cellulitis (involves tissues posterior to the septum) [1, 2]. Orbital cellulitis is an ophthalmic emergency, which is associated with sight-threatening adverse effects, such as loss of vision due to compressive optic neuropathy, central retinal artery and vein occlusion [11, 12]. Diagnosis and rapid treatment reduces morbidity and mortality [15, 16] The purpose of this retrospective study was to evaluate and compare the etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis and abscess in order to have better understanding of this sight and life threatening condition. Orbital cellulitis is an ophthalmic emergency, which is associated with vision-threatening adverse effects. The purpose of this study is investigating etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis
