UNASSIGNED: To explore the application value of infrared thermography (IRT) technique assisted peroneal artery perforator flap in repairing oral and maxillofacial defects.
UNASSIGNED: The clinical data of 20 patients with oral and maxillofacial malignant tumors treated with peroneal artery perforator flap between October 2020 and December 2021 were retrospectively analysed. There were 13 males and 7 females, with an average age of 56.5 years (range, 32-76 years). There were 8 cases of tongue cancer, 5 cases of parotid gland cancer, 4 cases of buccal cancer, and 3 cases of mandibular gingival cancer; and 12 cases of squamous cell carcinoma, 3 cases of adenoid cystic carcinoma, and 5 cases of mucoepidermoid carcinoma. Color Doppler ultrasound (CDU) and IRT technique were performed before operation to locate the peroneal artery perforator and assist in the design of the flap. The sensitivity, specificity, positive predictive value, and negative predictive value of CDU and IRT technique were compared with the actual exploration during operation. The accuracy of CDU and IRT technique in detecting the number of peroneal artery perforator and the most viable perforating points was compared. The patients were followed up regularly to observe the recovery of donor and recipient sites, the occurrence of complications, and the recurrence and metastasis of tumors.
UNASSIGNED: The sensitivity, specificity, positive predictive value, and negative predictive value of peroneal artery perforators detected by IRT technique before operation were 72.22%, 50.00%, 92.86%, and 16.67% respectively, which were higher than those by CDU (64.17%, 33.33%, 84.62%, and 14.29% respectively). Forty-five peroneal artery perforators were found by CDU before operation, and 35 were confirmed during operation, with an accuracy rate of 77.8%; 43 \"hot spots\" were found by IRT technique, and 32 peroneal artery perforators were confirmed within the \"hot spots\" range during operation, with an accuracy rate of 74.4%; there was no significant difference between the two methods ( χ²=0.096, P=0.757). The accuracy rates of the most viable perforating points found by CDU and IRT technique were 80.95% (17/21) and 94.74% (18/19), respectively, and there was no significant difference between them ( χ²=0.115, P=0.734). The localization errors of CDU and IRT technique were (5.12±2.10) and (4.23±1.87) mm, respectively, and there was no significant difference between them ( t=1.416, P=0.165). All the perforator flaps survived, and the incisions of donor and recipient sites healed by first intention. All patients were followed up 5-18 months, with an average of 11 months. The skin flap was soft and had good blood supply, and the lower limb scar was concealed and the lower limb had good function. No lower limb swelling, pain, numbness, ankle instability, or other complications occurred, and no tumor recurrence and metastasis were found during the follow-up.
UNASSIGNED: Compared with the CDU, using the IRT technique to assist the preoperative peroneal artery perforator flap design to repair the oral and maxillofacial defects has a high clinical application value.
UNASSIGNED: 探讨红外热成像(infrared thermography,IRT)技术辅助腓动脉穿支皮瓣在修复口腔颌面部缺损中的应用价值。.
UNASSIGNED: 回顾分析2020年10月—2021年12月行腓动脉穿支皮瓣修复的20例口腔颌面部恶性肿瘤患者临床资料。男13例,女7例;年龄32~76岁,平均56.5岁。舌癌8例、腮腺癌5例、颊癌4例、下颌牙龈癌3例;鳞状细胞癌12例,腺样囊性癌3例,黏液表皮样癌5例。术前常规行彩色多普勒超声(color Doppler ultrasound,CDU)和IRT技术对腓动脉穿支进行定位并辅助设计皮瓣,与术中实际探查情况比较,分析CDU、IRT技术检查的灵敏度、特异度、阳性预测值和阴性预测值;比较CDU和IRT技术检测穿支数目及最具活力穿支点的准确性。术后定期随访,观察患者供受区恢复情况、并发症发生及肿瘤复发转移情况等。.
UNASSIGNED: 与术中探查结果比较显示,术前IRT技术检查腓动脉穿支的灵敏度、特异度、阳性预测值和阴性预测值分别为72.22%、50.00%、92.86%、16.67%,均高于CDU检查结果(分别为64.17%、33.33%、84.62%、14.29%)。术前CDU检查共发现腓动脉穿支45支,术中探查证实35支,准确率77.8%;IRT技术检查共发现43个“热点”,术中证实“热点”范围内腓动脉穿支32支,准确率74.4%;两者比较差异无统计学意义( χ²=0.096, P=0.757)。CDU和IRT技术检查发现的最具活力穿支点的准确率分别为80.95%(17/21)和94.74%(18/19),两者比较差异无统计学意义( χ²=0.115, P=0.734)。CDU与IRT技术的穿支定位误差分别为(5.12±2.10)、(4.23±1.87)mm,两者比较差异无统计学意义( t=1.416, P=0.165)。20例穿支皮瓣均成活,供、受区切口均Ⅰ期愈合。所有患者均获随访,随访时间5~18个月,平均11个月。皮瓣质地柔软、血运良好;下肢瘢痕隐蔽,功能良好。无下肢肿胀、疼痛、麻木、踝关节不稳定等并发症发生,随访过程中未见肿瘤复发和转移。.
UNASSIGNED: 与CDU比较,采用IRT技术辅助腓动脉穿支皮瓣术前设计修复口腔颌面部缺损具有较高的临床应用价值。.
