pubmed-article:19807989 | pubmed:abstractText | An antrochoanal polyp (ACP) originates from the maxillary antrum and simple excision results in high recurrence rates. Canine fossa puncture (CFP) has been proposed as an alternative method of accessing the entire maxillary antrum. To investigate the long-term effects of the CFP approach on changes in the maxillary sinus volume in pediatric patients with an ACP, we compared the sinus volume on the operated and normal sides, using preoperative computed tomography (CT), and postoperative CT performed at least 3 years after the procedure. The surgical outcomes were also assessed using endoscopic and CT findings. | lld:pubmed |
