深圳一名6岁患儿因额头外伤拍CT检查时，意外发现双侧鼻腔内藏有6颗磁力珠[1]。据了解，这些磁珠来自患儿2021年购买的磁力珠玩具，已滞留至少自那时起[1]。经高清鼻内镜探查确认，磁珠已被长出的肉芽包裹、双向磁吸紧密粘连，其中右侧4颗、左侧2颗[1]。
深圳市龙岗区耳鼻咽喉医院儿童耳鼻咽喉科医疗团队采用精细化内镜微创方案进行手术，逐层分离肉芽、缓慢松动粘连珠子，最终完整取出全部6颗磁珠[1]。该手术避免了患儿出现鼻中隔穿孔、软骨坏死等终身损伤[1]。
医疗团队提醒，鼻腔异物不一定伴有流脓涕、鼻塞等典型症状，家长需留意单侧鼻塞、少量鼻出血、鼻腔异味、频繁揉鼻等预警信号[1]。程超主任指出，双侧磁珠隔空相吸会持续压迫阻断鼻中隔血液供应，久而久之造成软骨坏死；一旦形成鼻中隔穿孔，孩子将常年反复鼻出血、鼻腔干燥，呼吸时出现哨音，严重者需二次手术修补[1]。
A six-year-old child in Shenzhen was found to have six magnetic beads lodged in both nasal passages, with the foreign objects discovered incidentally during a CT scan following a head injury [1]. The magnetic beads, consisting of four on the right side and two on the left, originated from a magnetic toy purchased in 2021 and had remained in the child's nose for at least since that year [1]. High-resolution nasal endoscopy confirmed that the beads had become encased in granulation tissue and were tightly bound together through magnetic attraction [1].
Medical staff at Longgang District Ear, Nose and Throat Hospital in Shenzhen employed a refined endoscopic minimally invasive surgical approach to carefully separate the granulation tissue and gradually dislodge the adhesive beads, ultimately extracting all six magnetic beads intact [1]. The procedure successfully prevented serious complications including nasal septal perforation and cartilage necrosis [1]. According to the medical team, magnetic beads on opposite sides of the nasal septum continuously attract each other, progressively obstructing blood supply to the septum and potentially causing cartilage death over time [1]. If left untreated and a septal perforation develops, the child would face chronic recurrent nosebleeds, nasal dryness, whistling sounds during breathing, and in severe cases would require secondary surgical repair [1].
Physicians stressed that nasal foreign bodies may not present typical symptoms such as purulent nasal discharge or congestion, and parents should watch for warning signs including unilateral nasal obstruction, minor nosebleeds, unusual nasal odor, and frequent nose rubbing [1].
