Choanal atresia is a congenital anomaly usually diagnosed at birth. This case involves bilateral choanal atresia in a newborn with respiratory difficulties in whom there is an inability to pass a #8 French catheter through the nose. In contrast, unilateral choanal atresia causes a variable degree of nasal obstruction that may delay the diagnosis. We report a case of unilateral choanal atresia in a 9-year-old boy diagnosed as having chronic sinusitis with allergic rhinitus. Initial interpretation of a computerized, tomographic (CT) examination confirmed the diagnosis of chronic sinusitis. The definitive diagnosis, however, was made by endoscopic evaluation. A review is presented of the epidemiology, clinical presentation, differential diagnosis, and contemporary surgical management for unilateral choanal atresia.
后鼻孔闭锁是一种通常在出生时被诊断出的先天性异常。该病例涉及一名患有呼吸困难的新生儿双侧后鼻孔闭锁，无法通过8号法国导管经鼻。相比之下，单侧后鼻孔闭锁会导致不同程度的鼻塞，这可能会延迟诊断。我们报告一例9岁男孩单侧后鼻孔闭锁病例，该男孩被诊断为患有慢性鼻窦炎伴过敏性鼻炎。计算机断层扫描（CT）检查的初步解读证实了慢性鼻窦炎的诊断。然而，最终诊断是通过内镜评估做出的。本文对单侧后鼻孔闭锁的流行病学、临床表现、鉴别诊断和当代外科治疗进行了综述。
