This may be brought on directly, as in the case of nasal piercings, or indirectly, as by long-term topical drug application, including intranasal ethylphenidate, methamphetamine, cocaine, crushed prescription pills, or decongestant nasal sprays, chronic epistaxis, aggressive digital nasal cleaning (nose picking) and as a complication of nasal surgery like septoplasty or rhinoplasty. Much less common causes for perforated nasal septums include rare granulomatous inflammatory conditions like granulomatosis with polyangiitis. It has been reported as a side effect of anti-angiogenesis drugs like bevacizumab. ==Signs and symptoms== A perforated septum can vary in size and location, and is usually found deep inside the nose. It may be asymptomatic, or cause a variety of signs and symptoms. Small perforations can cause a whistling noise when breathing. Larger perforations usually have more severe symptoms. These can be a combination of crusting, blood discharge, difficulty breathing, nasal pressure and discomfort. The closer the perforation is to the nostrils, the more likely it is to cause symptoms. 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 septum perforation」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.
