Abstract：
Retropharyngeal infections (RPIs) are uncommon in young infants and are difficult to diagnose due to their non-classical presentation. RPI can occasionally be complicated with multiple cranial nerve palsies but rarely in isolation. Isolated hypoglossal nerve palsy (HNP) due to RPI has been described in the literature but mostly in older children and adults. Assessment for hypoglossal nerve function is challenging in a young infant because the conventional signs of hypoglossal nerve dysfunction are difficult to elicit in this age group. Early recognition and treatment of RPI are associated with good HNP recovery. We present a case of a young infant with tongue deviation and difficulty with feeding attributed to an isolated HNP caused by suppurative retropharyngeal lymphadenitis. The infant underwent incision and drainage with complete recovery of the tongue function after 8 weeks.
摘要：
咽后感染（RPI）在幼儿中并不常见，并且由于其非经典表现而难以诊断。RPI偶尔会并发多发性颅神经麻痹，但很少孤立。文献中已经描述了由于RPI引起的孤立的舌下神经麻痹（HNP），但大多数发生在年龄较大的儿童和成人中。在年轻的婴儿中，对舌下神经功能的评估具有挑战性，因为在该年龄段很难引起舌下神经功能障碍的常规体征。RPI的早期识别和治疗与良好的HNP恢复相关。我们介绍了一例由于化脓性咽后淋巴结炎引起的孤立性HNP引起的舌头偏斜和进食困难的婴儿。8周后，患儿行切口引流，舌功能完全恢复。
