A technique that maintains dual soft tissue pedicles to the palatal and labiobuccal areas in segmental total maxillary osteotomy was studied with respect to the effects on osseous revascularization and healing. Single-stage four-segment total maxillary osteotomies were performed by this method in five adult male rhesus monkeys. The animals were killed at intervals from immediately to 28 days after surgery. Histologic examination of the maxillae revealed that this technique is sufficient to support total maxillary osteotomy through 28 days. The soft tissue flap provided adequate blood supply to the anterior maxillary segment. All bony segments were mobilized, with only transient effects on bone healing and viability. The marginal osteonecrosis observed did not appear to be progressive. The effects of this procedure on the pulp are not clear.
一项关于节段性全上颌骨截骨术中维持腭部和唇颊部双软组织蒂的技术，针对其对骨再血管化和愈合的影响进行了研究。采用该方法对五只成年雄性恒河猴进行了单阶段四段式全上颌骨截骨术。术后从即刻到28天期间每隔一段时间处死动物。对上颌骨的组织学检查表明，该技术足以在28天内支持全上颌骨截骨术。软组织瓣为上颌前部节段提供了充足的血液供应。所有骨段均被移动，对骨愈合和活力仅有短暂影响。观察到的边缘性骨坏死似乎并未进展。该手术对牙髓的影响尚不清楚。
