이하선수술시 Frey 증후군의 예방을 위한 흉쇄유돌근피판의 효과

Frey’s syndrome is symptom complex consisting of flushing, sweating around preauricular and cheek skin during mastication. It is also designated as gustatory sweating or auriculotemporal nerve syndrome. Postoperative Frey’s syndrome may occur with varying degree of symptom severity and the incidence after parotidectomy is variable. Casler and Conley (1991) reported that 10% of post-parotidectomy patients complained of gustatory sweating, 30% of patients were aware of their symptoms after being asked for their symptoms and over 90% of patients showed positive starch-iodine test. Authors investigated the effect of superiorly based sternocleidomastoid muscle (SCM) flap for the prevention of Frey’s syndrome and depression of retromandibular region after parotidectomy. Frey’s syndrome was developed 18% in group using SCM flap and 56% in group without SCM flap. Seventeen out of forty cases (42.5%) with SCM flap showed good cosmetic results without retromandibular depression. (J Clinical Otolaryngol 2000;11:104–108)
