Osteoplasty of the frontal sinus (bone lid operation) consists of the excision of a piece of bone from the anterior surface of the frontal sinus. A circular saw with an extremely fine saw blade is used. The ensuing cut is thus extremely narrow and the excised bone lid can be reimplanted exactly, flush with the neighbouring bone from which it was excised. Primary healing takes place without the development of intermediary connective or cartilagenous tissue. Only circumscribed pathological lesions of the diseased mucous membrane are removed. Otherwise, healing is promoted by improved drainage and ventilation. For this purpose a channel leading to the nose is created. In order to ensure that this channel stays open it is lined by dura or mucous membrane. The latter is put into place and fixed by an inflatable balloon acting as a tampon. The balloon is traversed by a tube which guarantees adequate drainage and ventilation during healing of the lining material in the channel.
额窦骨成形术（骨瓣手术）包括从额窦前表面切除一块骨头。使用带有极细锯片的圆锯。因此，随后的切口极其狭窄，切除的骨瓣可以精确地重新植入，与切除它的相邻骨头齐平。一期愈合过程中不会形成中间结缔组织或软骨组织。仅切除患病黏膜的局限性病变。否则，通过改善引流和通气促进愈合。为此，创建一条通向鼻腔的通道。为确保该通道保持开放，用硬脑膜或黏膜衬里。后者通过充当填塞物的可充气气球放置并固定。气球由一根管子穿过，在通道内衬材料愈合期间保证充分的引流和通气。
