Despite advances in endoscopic techniques, there are still instances when the frontal sinus must be approached externally. Given its variable anatomy, the frontal sinus continues to present a challenge to the surgeon. Our rule of thumb capitalises on the consistent embryological development of the frontal sinus, aiding safe external access.
The presented stepwise approach includes trephination, fenestration, an osteoplastic flap and obliteration. The obliteration procedure has produced good results in managing those patients with disabling symptoms despite multiple endoscopic procedures.
尽管内镜技术不断进步，但仍有一些情况下需要经外部入路处理额窦。由于其解剖结构的多变性，额窦仍然给外科医生带来挑战。我们的经验法则利用了额窦一致的胚胎发育，有助于安全地进行外部入路。
所提出的分步方法包括环钻、开窗、骨成形瓣和闭塞。对于那些尽管经过多次内镜手术仍有致残症状的患者，闭塞术在处理这些患者方面取得了良好的效果。
