Ethmoid Sinus Mucocele Manifesting as Acute Ophthalmoplegia and Ptosis Rapidly Exacerbated by COVID-19 Infection: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A sinus mucocele is a dilated, epithelial-lined cystic lesion containing encapsulated mucus. Although its etiology remains uncertain, secondary infection may transform it into a pyocele. A 68-year-old female presented with sudden-onset ophthalmoplegia, ptosis, and blurred vision during the acute phase of COVID-19 infection. Physical examination and imaging identified an ethmoid sinus mucocele causing significant orbital compression. The patient underwent urgent endoscopic marsupialization. Intraoperative findings revealed increased internal pressure within the mucocele. Postoperatively, her ocular motility and ptosis improved immediately, with a full recovery of visual acuity within two weeks. This case suggests that COVID-19-associated mucosal inflammation or immune dysregulation may lead to the rapid expansion of pre-existing asymptomatic mucoceles. Clinicians should consider mechanical sinus lesions in the differential diagnosis of acute cranial nerve palsies during COVID-19 infection to ensure timely surgical decompression.
