They are overgrowths of the mucosa that frequently accompany allergic rhinitis, and are freely movable and nontender. ==Signs and symptoms== Nasal polyps are usually classified into ''antrochoanal'' polyps and ''ethmoidal'' polyps. Antrochoanal polyps arise from the maxillary sinuses and are the much less common, ethmoidal polyps arise from the ethmoidal sinuses. Symptoms of polyps include nasal congestion, sinusitis, anosmia (loss of smell), and secondary infection leading to headache. They may be removed by surgery, but are found to recur in about 70% of cases. Sinus surgery requires a great amount of precision as this involves risk of damage to orbit matter. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nasal polyp」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
