睑板缺损以往曾用耳软骨代替。近年来,我们依据Seigel 的论述,采用硬腭粘膜代替缺损的睑板,取得满意效果。手术时,眼面部常规消毒,在患者右侧腭部相当于硬腭后份区。此区腭部粘膜光滑,适应与角膜接触,又无大血管。用利多卡因加肾上腺素局麻,使局部粘膜隆起,取下1.0×3.0cm~2大小深至腭骨膜的粘膜。切透粘膜后进行钝性剥离,掀起硬腭粘膜。注意不要损伤软腭连接处深部的腭动脉。取移植片后充分止血,缺损处用碘仿纱条压迫,缝线固定在纱条于牙缝隙之间。12天后拆线。
Meconium defects have been replaced by ear cartilage in the past. In recent years, we based on Seigel’s argument, the use of hard palate mucosa instead of defect tarsal, and achieved satisfactory results. Surgery, the routine ophthalmic disinfection of the palate in the right palate is equivalent to the hard palate area. Palate mucosa in this area is smooth, to adapt to contact with the cornea, no major blood vessels. With lidocaine plus epinephrine local anesthesia, the local mucosal uplift, remove the size of 1.0 × 3.0cm ~ 2 palatal mucosa deep. Penetrating mucosa after blunt dissection, set off the palate mucosa. Be careful not to damage the soft palate junction deep palatal artery. Take full hemostasis after transplantation, the defect with iodoform gauze pressure, suture fixed in the gap between the teeth in the tooth. 12 days after the stitches.
