Behind the Unilateral Rhinorrhea: Delayed Pediatric Intranasal Foreign Bodies Presenting as Chronic Sinonasal Disease and Severe Complications.

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
Background and Clinical Significance: Intranasal foreign bodies are common pediatric otolaryngologic emergencies and are usually diagnosed and removed without difficulty. However, delayed or occult retention may mimic chronic unilateral sinonasal disease and occasionally result in severe inflammatory or infectious complications. This study presents three illustrative pediatric cases of delayed intranasal foreign bodies supported by a seven-year institutional experience. Case Presentation: A retrospective review was conducted of all pediatric patients (≤16 years) presenting with intranasal foreign bodies at a secondary referral hospital between January 2019 and May 2026. Demographic characteristics, clinical presentation, management, and outcomes were reviewed to provide institutional context. Among 82 identified patients, three children with delayed diagnosis and severe complications were selected for detailed presentation because they represented distinct clinical manifestations of prolonged foreign body retention. These included chronic unilateral rhinosinusitis caused by a retained peanut fragment, a medial orbital subperiosteal abscess secondary to a retained plastic nasal piercing component, and a foreign-body granuloma associated with retained nasal packing material. The remaining patients underwent uncomplicated removal, predominantly in the emergency department. Conclusions: The presented cases illustrate the diverse spectrum of complications that may occur following delayed intranasal foreign body retention in children. Persistent unilateral foul-smelling rhinorrhea, nasal obstruction, recurrent unilateral epistaxis, or refractory unilateral sinonasal symptoms should prompt careful evaluation for a retained foreign body. By combining detailed case descriptions with institutional experience, this report highlights the importance of maintaining a high index of suspicion and timely endoscopic management in children with persistent unilateral sinonasal symptoms.
