Postnasal drip (PND) is a common clinical complaint, yet its physiologic basis and appropriate treatment have been inadequately addressed in the medical literature. PND may be caused by a variety of conditions involving the nose and throat. Often, the symptom is not caused by actual secretions draining from the nose into the pharynx. In many instances, no definitive cause can be identified. Empiric treatment for PND symptoms should be guided by associated symptoms that suggest either a sinonasal cause or gastroesophageal reflux. Rarely, PND may be a symptom of a serious process such as a mass lesion in the pharynx or a malignancy and thus referral to an otolaryngologist is appropriate if symptoms are persistent, unexplainable, or associated with warning signs of malignancy.
鼻后滴注（PND）是一种常见的临床主诉，但在医学文献中，其生理基础和适当的治疗方法尚未得到充分解决。PND 可能由涉及鼻和喉咙的各种情况引起。通常，该症状不是由实际从鼻子排入咽部的分泌物引起的。在许多情况下，无法确定明确的病因。PND 症状的经验性治疗应根据提示鼻-鼻窦原因或胃食管反流的相关症状来指导。很少情况下，PND 可能是严重疾病的症状，如咽部肿块或恶性肿瘤，因此如果症状持续、无法解释或伴有恶性肿瘤的警告症状，应将患者转介给耳鼻喉科医生。
