脫細(xì)胞真皮基質(zhì)預(yù)防腮腺術(shù)后Frey綜合征臨床療效的回顧性研究
[Abstract]:Objective: to evaluate the clinical efficacy of acellular allogenic dermal matrix (ADM) in preventing Frey syndrome after parotid gland operation. Methods: from 2005 to 2010 161 patients with parotid benign tumor were treated in oral and maxillofacial surgery of Shandong Provincial Hospital. The 161 patients were assigned to a retrospective study, the routine operation group (nnm87): the superficial parotid lobe, parotid part or whole parotid lobe were surgically dissected without any filling material, and the tissue patch group (nnm74): the superficial parotid lobe was performed. After parotid partial or total parotid lobectomy, ADM. was implanted between the remaining parotid tissue and the parotid masseter fasciocutaneous flap according to the size of the defect. The occurrence of Frey syndrome was evaluated by questionnaire and 40 patients were randomly selected from each group for objective evaluation by Minor iodide starch test. The differences between the two groups of experimental data were checked by chi-square with SPSS19.0 software. Results: according to the results of questionnaire, 36 (41.38%) of 87 patients in routine operation group had subjective symptoms of Frey syndrome, and 15 (20.27%) of 74 patients in implanted tissue patch group had subjective symptoms of Frey syndrome. Chi-square test showed that there was statistical significance in 蠂 ~ 2 ~ 2 ~ (8.23) P _ (0.05). According to the results of Minor iodine-starch test, 21 (52.5%) of 40 patients in the routine operation group had the objective symptoms of Frey syndrome, and the tissue patch group was implanted into the tissue patch group. Objective symptoms of Frey syndrome were found in 10 patients (25.0%). Chi-square test was performed. At the same time, we studied the effect of parotid gland excision site and size on Frey syndrome after parotid surgery. There was no significant difference between the two groups in both conventional operation group and implanted tissue patch group (P0.05). Therefore, it is not considered that the location and size of parotid gland extirpation has a significant effect on the probability of Frey syndrome after parotid surgery. The results of questionnaire survey showed that 4 (4.60%) patients in the routine operation group had local pain in the operation area and 53 (71.62%) patients in the implanted tissue patch group. Chi square test, P0.05, has statistical significance. No other adverse reactions such as severe allergies were found in all patients after operation. Conclusion: xenogeneic acellular dermal matrix plays a role in the prevention of Frey syndrome more than 3 years after parotidectomy. It is an effective method to prevent Frey syndrome, but it can also lead to postoperative complications such as local pruritus and pain.
