Diseases of the paranasal sinuses--especially of the anterior ethmoid sinus--may affect tubal function. Acute and chronic sinus inflammations cause alterations in the normal pathways for secretions out of the sinus system. The normal secretion pathways usually bypass the orifice of the eustachian tube in the nasopharynx. Excessive or infected mucus can then be transported directly over the tubal orifice to cause its obstruction and promote ascending infections into the middle ear. We have found that nasal endoscopy proves to be very helpful in detecting even "hidden" pathologies due to sinus disease in key areas in the middle meatus, and furthermore allows a direct visualization of the tubal orifice. Functional endoscopic surgery has also enabled us to clear diseased and stenotic areas involving the sinus ostia with minimal procedures. Normal drainage and ventilation are reestablished via the physiologic sinus ostia and thus help to normalize tubal function.
鼻窦疾病——尤其是前筛窦疾病——可能会影响咽鼓管功能。急慢性鼻窦炎会导致鼻窦系统分泌物正常排出途径发生改变。正常的分泌物排出途径通常绕过鼻咽部的咽鼓管开口。过多或感染的黏液随后可直接通过咽鼓管开口运输，导致其阻塞，并促使感染蔓延至中耳。我们发现，鼻内镜检查对于发现中鼻道关键区域因鼻窦疾病导致的甚至“隐匿”病变非常有帮助，而且还能直接观察咽鼓管开口。功能性内镜手术也使我们能够通过最小的手术操作清除涉及鼻窦开口的病变和狭窄区域。通过生理性鼻窦开口重新建立正常引流和通气，从而有助于使咽鼓管功能恢复正常。
