To evaluate the patient-reported pain perception after palatal graft harvesting during a 4 weeks healing period
MATERIALS & METHODS: Ninety patients, scheduled for different periodontal and peri-implant plastic surgeries requiring palatal mucosal graft harvesting, were consecutively recruited. Mucosal thickness was measured at the donor sites with an ultrasonic device prior to the surgeries. Graft thickness, length, and width were assessed after harvesting, and the wound areas were calculated. Based on a Visual Analogue Scale (VAS), the patients were asked to report their perceived pain after the intervention and 1, 3, 7, 14, 21 and 28 days thereafter.
Pain was most pronounced on the first postoperative day and decreased within the course of time. Graft thickness directly correlated with the amount of pain perceived while increased palatal mucosal thickness before and after graft harvesting decreased pain levels. The denuded wound surface area, however, did not influence the perceived pain level.
The wound depth at the donor site (graft thickness) was positively correlated with the patient's perception for pain. The wound surface area, however, did not influence the perceived pain level.
评估腭部移植物采集后 4 周愈合期内患者的疼痛感知。
连续招募了 90 名计划进行不同牙周和种植体周围整形手术的患者,这些手术需要采集腭部黏膜移植物。在手术前,使用超声设备测量供体部位的黏膜厚度。在采集后评估移植物的厚度、长度和宽度,并计算伤口面积。根据视觉模拟评分(VAS),患者在手术后、第 1、3、7、14、21 和 28 天被要求报告他们的疼痛感知。
疼痛在术后第 1 天最为明显,随后在时间内逐渐减轻。移植物厚度与感知到的疼痛量直接相关,而在移植物采集前后增加的腭部黏膜厚度降低了疼痛水平。然而,裸露的创面面积并不影响感知到的疼痛水平。
供体部位(移植物厚度)的伤口深度与患者的疼痛感知呈正相关。然而,创面面积并不影响感知到的疼痛水平。
