Description
「副鼻腔炎」という用語は、一般的に、バクテリア、ウィルス、菌(かび)、アレルギーまたはその組み合わせによって引き起こされる副鼻腔の一切の炎症または感染を指す。慢性の副鼻腔炎(例えば、3ヵ月ほど継続)では、アメリカでは内科医受診回数が年間1800万回から2200万回となっている。
● 頭痛または顔面痛
● 鼻づまりまたは後鼻漏
● 片方または両方の鼻孔からの呼吸困難
● 口臭
● 上歯の痛み
FESSにおいては、内視鏡が鼻に挿入され、内視鏡を介した視覚化に基づいて、外科医は、病変組織または肥大組織を除去することができ、また、副鼻腔口を広げて副鼻腔の通常の粘液排出を回復することができる。各種FESS法は、一般的に、患者が全身麻酔された状態で行われる。
拡張用バルーンを用いた副鼻腔介入の方法および装置は、これまで、米国特許第2,525,183号(Robison)および米国特許公開第2004/0064150 A1(Becker)号で開示されている。例えば、米国特許第2,525,183号(Robison)では、副鼻腔手術後に挿入して副鼻腔内で膨張させることができる膨張式圧力装置が開示されている。この特許では、複雑な鼻の生体組織を柔軟に通り抜けて自然な副鼻腔口に出入りする装置設計および方法は開示されていない。また、バルーン材料を論じた内容は、骨質の副鼻腔口の拡張には不適当である可能性が最も高いゴムなどの軟質材料にかなり限定される。
