带蒂瓣联合结缔组织移植术、翻瓣术治疗唇颊侧牙龈瘤的临床效果比较 #br# #br#

目的 回顾性分析带蒂瓣联合结缔组织移植术、翻瓣术治疗唇颊侧牙龈瘤切除术后术区软组织缺损的临 床效果。方法 回顾性分析2017年1月—2019年12月在天津市宝坻区人民医院口腔科行手术治疗的唇颊侧牙龈瘤 80例患者临床资料，根据术式的不同，将行翻瓣术纠正术区软组织缺损的38例患者纳入对照组，行带蒂瓣联合结缔 组织移植术的42例患者纳入观察组。比较分析2组患者术前、术后3个月和术后6个月的龈沟出血指数（SBI）、牙龈 指数（GI）、牙周探诊深度（PD）；比较 2 组术后即刻、术后 3 个月和术后 6 个月的角化龈宽度（KGW）、根面覆盖率 （RC）；统计美学效果及患者手术满意度。 结果2组术后3个月和6个月的SBI、GI、PD均较术前显著下降，且观察组 显著低于对照组（P＜0.05）。对照组术后即刻的KGW显著高于观察组，但在术后3个月和6个月时均显著低于观察 组（P＜0.05）；观察组术后即刻、术后3个月和6个月的RC均显著高于对照组（P＜0.05）。观察组术后6个月的美学 效果优良率和患者手术满意率均为97.6%，均显著高于对照组的84.2%和78.9%（P＜0.05）。 结论对仅波及唇颊侧 的牙龈瘤患者采用带蒂瓣联合结缔组织移植术纠正术区软组织缺损效果满意，相对于采用翻瓣术纠正术区软组织 缺损美学效果更好，患者手术满意度更高。

Comparison of clinical effects of pedicled flap combined with connective tissuetransplantation and flap flap operation in the treatment of lip face gingival tumor #br#

Objective To analyze retrospectively the clinical effects of pedicled flap combined with connective tissue transplantation and flap surgery in the treatment of soft tissue defects in the surgical area after resection of gingival tumor on the lib and buccal side. MethodsThe clinical data of 80 patients with lib and buccal gingival tumor who were hospitalized in stomatology department of Tianjin Baodi Hospital from January 2017 to February 2019 were analyzed retrospectively. According to the different operation methods, 38 patients who underwent flap operation to correct the soft tissue defects in the operation area were included in the control group, 42 patients who underwent pedicled flap combined with connective tissue transplantation to correct the soft tissue defects in the operation area were included in the observation group. The sulcus bleeding index (SBI), gingival index (GI) and periodontal probing depth (PD) were recorded before operation, 3 months and 6 months after the operation in the 2 groups. The keratinized gingival width (KGW) and root coverage (RC) were compared immediately, 3 months and 6 months after the operation between the 2 groups. Results The levels of SBI, GI and PD were significantly decreased 3-month and 6-month after operation in the 2 groups, and those were significantly lower in observation group than those in the control group (P＜0.05). KGW was significantly higher immediately after operation in the control group than that in the observation group (P＜0.05), but it was significantly lower at 3 months and 6 months after operation in the control group than that in the observation group (P＜0.05). The RC values were significantly higher immediately after operation and 3 months and 6 months after operation in the observation group than those in the control group (P＜0.05). The excellent and good rates of aesthetic effect and patient satisfaction 6 months after operation were 97.6% and 97.6% in the observation group, which were significantly higher than 84.2% and 78.9% in the control group (P＜ 0.05). ConclusionFor patients with gingival tumors that only affect the lip and buccal side, the effect of pedicled flap combined with connective tissue transplantation to correct soft tissue defects in the operation area is satisfactory. Compared with the use of flap surgery to correct soft tissue defects in the operation area, the aesthetic effect is better, and the patient's surgical satisfaction is higher.
