The Draf 3 frontal sinusotomy, or modified Lothrop procedure has been used to treat recalcitrant rhinosinusitis, frontal sinus mucocoeles or to provide access for cerebrospinal fluid leaks, frontoethmoid fractures, frontal sinus tumors and skull base tumors.
To describe authors approach to the "Outside-In Frontal Drill-Out".
Descriptive.
The "Outside-In" frontal drill-out is an approach that emphasizes the early identification of the first olfactory neuron, maximization of bone removal, and preservation of the posterior table mucosa.
The advantages of this approach are it provides unobstructed view and identifies anatomic limits early, bone removal is fast and efficient; it is safe, and it is a robust technique based upon fixed anatomic landmarks.
Draf 3额窦切开术，即改良Lothrop手术，已被用于治疗顽固性鼻-鼻窦炎、额窦黏液囊肿，或用于处理脑脊液漏、额筛窦骨折、额窦肿瘤和颅底肿瘤。
描述作者采用的“由外向内额窦钻孔术”方法。
描述性研究。
“由外向内”额窦钻孔术是一种强调早期识别第一嗅神经元、最大限度去除骨质并保留后筛窦黏膜的方法。
该方法的优点是视野清晰且能早期确定解剖界限，骨质去除快速高效；安全可靠，是基于固定解剖标志的可靠技术。
