目的评价不同组织瓣在口腔上颌窦瘘修复中的应用。方法收集2000年3月-2007年6月,在我院就诊的口腔上颌窦瘘患者26例,分别采用带蒂颊脂垫瓣、颊侧黏骨膜瓣、腭黏骨膜瓣修复转移修复。结果7例采用带蒂颊脂垫瓣修复者均Ⅰ期愈合,采用颊侧黏骨膜瓣、腭黏骨膜瓣修复者各有1例失败,Ⅱ期采用带蒂颊脂垫瓣修复均正常愈合。术后随访3个月～2年,全部患者创口愈合良好,颊侧黏骨膜瓣修补的患者术后口腔前庭沟均有不同程度变浅,采用带蒂颊脂垫瓣修复者无供区功能障碍和面部畸形。结论颊侧黏骨膜瓣、腭黏骨膜瓣能良好地封闭瘘孔较小的口腔上颌窦瘘,对于瘘孔较大、颊侧黏骨膜瓣或腭黏骨膜瓣无法完全封闭瘘孔者或术后需行活动义齿修复者,需采用带蒂颊脂垫瓣转移修复。
Objective To evaluate the application of different tissue flap in the repair of oral maxillary sinus fistula. Methods Twenty - six patients with oral maxillary sinus fistula who were treated in our hospital from March 2000 to June 2007 were collected. The pedicled buccal fat pad flap, buccal mucoperiosteal flap and palatal mucoperiosteal flap were used to repair and transfer the wounds. Results All the 7 patients who underwent pedicled buccal fat pad were cured in the first stage. Buccal mucoperiosteal flap and palatal mucoperiosteal flap were repaired in 1 case, while in the second stage, the pedicled buccal fat pad flap was repaired. The patients were followed up for 3 months to 2 years. All the wounds healed well. The oral vestibular ditch in patients with buccal mucoperiosteal flap was lightened to varying degrees after operation. The patients with pedicled buccal fat pad flap had no functional impairment And facial deformities. Conclusions The buccal mucoperiosteal flap and the palatal mucoperiosteal flap can close the small oral maxillary sinus fistula with good fistula. For those with large fistula, buccal mucosa flap or palatal mucoperiosteal flap can not completely close the fistula or after operation Need to move the denture prosthesis, the need to use pedicled buccal fat pad flap transfer repair.
