[Differential diagnosis of acute maxillary ethmoiditis complicated by orbital abscess with dacryocystitis and phlegmon of the lacrimal sac in children].

Introduction: The differential diagnosis of orbital complications of rhinosinusitis with diseases of the lacrimal sac in childhood remains unresolved both due to the similarity of the symptoms of the diseases and due to certain diagnostic difficulties requiring computed tomography.

Objective: To develop an algorithm for routing a patient to the emergency department of a multidisciplinary emergency hospital based on clinical and diagnostic distinctive features of sinusitis with orbital complications and diseases of the lacrimal sac with reactive edema of the eyelids.

Materials And Methods: A retrospective cohort analysis of children's medical histories, who were treated in the otorhinolaryngological and ophthalmological departments of the Morozovskaya Children's City Clinical Hospital during 2022 was performed for orbital complications of rhinosinusitis or dacryocystitis with reactive edema of the eyelids.
