上颌骨鼻腔口内暴露法能避免外部瘢痕,鼻腔和面中1/3的暴露不受限制,可以全部切除内翻性乳头状瘤。Denker等用扩大的Caldwell-Luc手术切除上颌面骨,除去鼻外侧壁进入鼻腔。这种方式提供良好的局部进路,但由于唇和鼻软组织使暴露受限制。采用Weber-Fergusson切口消除了此种缺陷,但这种方法限于一侧并有广泛的瘢痕形成。上颌骨鼻腔口内进路的优点在于手术野可以根据病变范围变更和扩大,无外部瘢痕,术后合并症少。手术用全麻并用含有肾上腺素的利多卡因注射入鼻部软组织和颊切口区内。切口位于唇龈和颊龈沟内,通过中线扩展至二侧上颌粗隆。切至骨膜,将面部软组织从上颌骨前面游 Oral maxillary nasal exposure method to avoid external scars, nasal cavity and surface exposure to 1/3 unlimited, you can completely remove the inverted papilloma.

This approach provides good local access, but limited exposure due to lip and nasal soft tissue. The use of Weber-Fergusson incision to eliminate such defects, but this method is limited to one side and a wide range of scarring. The advantage of maxillary intranasal approach is that the surgical field can be altered and expanded according to the extent of the lesion without external scarring and less postoperative complications. Surgery with general anesthesia and injection of lidocaine containing epinephrine nasal soft tissue and cheek incision area. The incision is located in the gingiva and cheek gingival sulcus, extending through the midline to the bilateral maxillofacial. Cut to the periosteum, swim the facial soft tissue from the front of the maxilla
