[Diagnosis and treatment of 11 cases of subperiosteal orbital abscess caused by acute sinusitis].

The aim of this study is to explore the diagnosis, clinical manifestations and surgical treatment experience of acute sinusitis complicated with orbital subperiosteal abscess. The clinical data of 11 patients with acute sinusitis complicated by orbital subperiosteal abscess from 1 year and 8 months to 50 years were retrospectively analyzed, including clinical manifestations, imaging manifestations, bacteriological examinations, surgical methods and therapeutic effects. All patients were given antibacterial drugs, glucocorticoids, and surgery. All 11 patients had unilateral lesions. The imaging examinations all supported the appearance of orbital subperiosteal abscess. Nine patients underwent nasal endoscopic sinus opening+SPOA incision and drainage, 2 patients underwent nasal endoscopic sinus opening+ultrasound guided abscess puncture. Eyelid swelling and exophthalmia of all patients were alleviated when discharged. Ten of the 11 patients had no visual acuity change, and one patient had light perception only when she came to the hospital and recovered to 0.05 when discharged, there was no change in visual acuity after 3 months follow-up. The bacterial cultures of nasal secretion or pus were positive in 7 cases, the main pathogenic bacteria were Staphylococcus aureus（3 cases, includes one case of MRSA）, Streptococcus anginosus（2 cases）, and Streptococcus intermedius（2 cases）. Rhinogenous orbital subperiosteal abscess has a rapid onset and progresses quickly. Once an abscess is formed, patients with poor conservative treatment should choose surgical treatment as soon as possible. The most common surgical method is nasal endoscopic sinus opening+SPOA incision and drainage. If the abscess is located above or above the eyeball, puncture or incision and drainage should be combined with ultrasound guidance.
