Clinical analysis of orbital and periorbital abscess in 17 patients

Objective: To discuss the etiology, clinical features and treatment principles of the orbital and periorbital abscess. Methods: A retrospective case series of 17 cases with orbital and periorbital abscess between July 2010 and November 2015 were conducted. All patients(,) clinical data including medical history, etiology, abscess location, paranasal sinus involvement, eye involvement, microbiological test results, imaging features, treatment and prognosis were summarized and analyzed. Results: In all 17 patients, there were 10 males and 7 females with age from 3.0 to 71.0 years (the average age was 33.9 years).Eight patients(,) bacterial cultures of the pus and secretion were positive in all 17 patients. Orbital and periorbital abscess patients could manifest decreased vision, redness and swelling of eyelid, conjunctival congestion and edema, ocular motility disorders, displacement of eyeball, increased orbital pressure, abscess rupture etc. CT showed us the soft tissue mass, accompanied with sinusitis or paranasal sinus mass. MR performed with the long T(1) and T(2) signals. The signals of the abscess cavity were not uniform. For the etiology,11 cases were secondary to sinusitis, including 1 case of diabetes; 2 cases with orbital fractures.One case was secondary to orbital fracture repairment surgery. One case was secondary to the remnant of sequestrum and foreign bodys in the wound after repairment surgery. One case was injured by the hard object. One case was secondary to paranasal sinuses large B-cell lymphoma. One case had diabetic history and the blood sugar was controlled unstablly. For the treatment, 7 cases were treated by the drainage surgery which was performed via the sinus with endoscopic and abscess resection performed via the skin.Two cases were treatment by the abscess resection only.One case was treated by the drainage surgery performed via the sinus with endoscopic only. Six cases were treated by the drainage surgery performed via the skin. One case was only administered intravenous antibiotic. Sixteen cases acquired well prognosis without serious complications except 1 case which occurred central retinal artery and vein occlusion. Conclusions: The orbital and periorbital abscess is mainly a complication of paranasal sinus infection, or secondary to trauma, surgery, tumor, etc; Orbital and periorbital abscess always manifest inflammatory neoplastic clinical features, the key of the diagnosis is to make sure the etiology; Incision and drainage of the abscess is the main treatment method when necessary. We can do the surgery with other departments to avoid the occurrence of serious complications.(Chin J Ophthalmol, 2017, 53: 588-593).
