Twenty consecutive patients (ten women and ten men; 14 - 66 years old) operated on from September 1993 to November 1995 were included in this study. The only inclusion criterion was a large polyp protruding from the nasal cavity into the nasopharynx. CT, MRI and endoscopic sinus surgery identified sites of choanal polyp (CP) origin as follows: maxillary sinus (n = 11), sphenoid sinus (n = 3), posterior ethmoids (n = 4), anterior ethmoids (n = 1), and lateral aspect of the head of the middle turbinate (n = 1). Light microscopy demonstrated no correlation between the site of CP attachment and its morphological appearance, but in two cases of CP (one originating from the sphenoid sinus and the other form the middle turbinate) morphological examination confirmed the diagnosis of inverted papilloma. Long-term follow-up in 15 patients revealed no cases of recurrence. The results obtained allow us to define three types of CP: antrochoanal, sphenochoanal, and ethmochoanal. In case of an unusual site of CP origin, the diagnosis of inverted papilloma should be considered.
本研究纳入了1993年9月至1995年11月期间连续接受手术治疗的20例患者（10名女性和10名男性；年龄14 - 66岁）。唯一的纳入标准是有一个从鼻腔突出至鼻咽部的大息肉。CT、MRI和鼻内镜鼻窦手术确定鼻后孔息肉（CP）的起源部位如下：上颌窦（n = 11）、蝶窦（n = 3）、后筛窦（n = 4）、前筛窦（n = 1）以及中鼻甲头部外侧（n = 1）。光镜检查显示CP附着部位与其形态外观之间无相关性，但在2例CP（1例起源于蝶窦，另1例起源于中鼻甲）中，形态学检查确诊为内翻性乳头状瘤。15例患者的长期随访显示无复发病例。所获得的结果使我们能够定义三种类型的CP：上颌鼻后孔型、蝶窦鼻后孔型和筛窦鼻后孔型。如果CP起源部位不寻常，应考虑内翻性乳头状瘤的诊断。
