Cerebrospinal fluid rhinorrhoea is the abnormal leakage of cerebrospinal fluid into the nasal cavity. The posterior wall of the frontal sinus can be the site of such leakage. Traditionally, these leaks were repaired via external osteoplastic or neurosurgical approaches. Despite advances in instrumentation, it is difficult to manage superiorly or laterally placed defects endoscopically. We present a new technique of endoscopic repair of frontal sinus posterior wall defects, via access holes drilled in the anterior wall of the frontal sinus.
Preliminary study involving patients presenting with frontal sinus cerebrospinal fluid leaks, with defects in the frontal sinus posterior wall, between 2006 and 2010.
Patients were treated in a tertiary referral centre for nose and sinus diseases. Patient records were reviewed and analysed.
Nine patients underwent external frontal sinusotomy under endoscopic vision. Repair was successful in all cases, with no complications. Follow up ranged from three months to three years.
External frontal sinusotomy and endoscopic repair is a simple, precise and cosmetically acceptable alternative to osteoplastic and major neurosurgical techniques for management of frontal sinus posterior wall defects. This new, previously undescribed technique enables otolaryngologists to play a role in managing such defects.
脑脊液鼻漏是指脑脊液异常漏入鼻腔。额窦后壁可能是此类漏液的部位。传统上，这些漏口通过外部骨成形术或神经外科手术方法进行修复。尽管器械有所进步，但在内镜下处理位于上方或外侧的缺损仍很困难。我们介绍一种通过在额窦前壁钻孔形成通道进行内镜修复额窦后壁缺损的新技术。
对2006年至2010年间出现额窦脑脊液漏且额窦后壁有缺损的患者进行的初步研究。
患者在一家三级鼻科和鼻窦疾病转诊中心接受治疗。对患者记录进行了回顾和分析。
9例患者在内镜直视下接受了外部额窦切开术。所有病例修复均成功，无并发症。随访时间为3个月至3年。
外部额窦切开术及内镜修复对于额窦后壁缺损的处理而言，是一种简单、精确且在美容方面可接受的替代骨成形术和大型神经外科技术的方法。这种新的、此前未描述过的技术使耳鼻喉科医生能够在处理此类缺损中发挥作用。
