The Observation Of The Efficacy To Prevent Frey’s Syndrome With The Parotid Masseteric Fascia Flap

Objective:Frey ’s syndrome is area common postoperative complication of parotidgland. Frey ’s syndrome patients make a big trouble in daily life and social situations, sofor the prevention of Frey’ s syndrome and treatment of domestic and foreign scholarshave carried on research and discussion, the therapies in parotid gland wound coveringbroad fascia flap, muscle flap, biology materials and so on, but after a long period ofclinical observation, less of the patients could accept to the risk of undergoingreoperation and the influence of additional incision for cosmetic effect; Therefore, withthe development of science and economy, people’s life quality requirements haveimproved, prevention of Frey ’s syndrome has more and more attentions by people,more ideal method of prevention is utmost lower surgery risks and the economic burden,and easily accepted by patients. In the parotid gland with retaining parotid masseterfascia in the operation of the method is a more reliable and effective prevention methods.Through retrospective study in this paper the first hospital affiliated to Dalian medicaluniversity clinical research data, the oral and maxillofacial surgery ward to see retainingparotid masseter fascia clinical effect in prevention of parotid Frey’s syndrome aftersurgery and to explore the clinical application value of the operation.Materials and methods: through the retrospective analysis of Dalian medicaluniversity first affiliated hospital of oral and maxillofacial surgery ward in2012yearsame surgery doctors reserve parotid masseter fascia of the Frey syndrome before andafter the surgery to prevent parotid gland tumor resection surgery in20cases,12caseswith parotid pleomorphic adenoma of parotid gland lymphoma,7cases of basal celladenoma1case. Operation method: the patient supine position. Head to thecontralateral, under local anesthesia before tragus it moves around the earlobe to theedge of the jaw type "S" incision. Cut the skin, subcutaneous tissue and jaw area underthe neck muscles. Different from conventional methods, flip flap, should cut parotidmasseter fascia, the parotid masseter fascia flap contains the flip up, along with all the direct exposure of the parotid gland tissue. Keep facial nerve dissection, resection of thelesions and parotid gland tissue. When flap is reset, close the wound, First，we shouldmake the parotid masseter fascia strictly suture, and then layered suture neck muscles,skin and subcutaneous tissue. At the end, we need to place one negative pressuredrainage bottle. The wound compression bandage. Tell patients postoperative blanddiet,dismantling the negative pressure drainage bottle after48h. Taking out the stitchesafter the surgery a week later.Results: during the follow-up period of6months to a year,20patients had noeating area sweating, skin temperature and with lateral swelling, incision healed wellpatients were satisfied. But three of the patients appeared with earlobe skin numbness,2cases with area tenderness symptoms. Iodine starch test were negative.Conclusion: postoperative prevention of Frey syndrome for parotid gland,retaining parotid masseter fascia method operation is simple, without additional incision,easy to master, is the ideal surgical method.
