Background |
The prevalence of Frey's syndrome (FS) after superficial parotidectomy in correlation to the sternocleidomastoid muscle flap (SCMMF) interposition is analyzed.
Methods |
A prospective nonrandomized controlled multicenter trial included 130 patients. During superficial parotidectomy, SCMMF was dissected, if excised specimens' volume exceeded 25 mL (SCMMF group). Follow-up examinations took place after 6, 12, and 24 months and included a Minor's test.
Results |
SCMMF was dissected in 30 (23.1%) patients. A total of 104, 80, and 68 patients completed the 1st, 2nd, and the 3rd follow-up, respectively. FS was detectable with nonvarying prevalence (46.3%, 45.6%, and 43.4%, respectively) during follow-up. The prevalence was higher in the SCMMF group (59.9%) than in the non-SCMMF group (41.8%; P = .92). The sweating area increased during follow-up (P = .12). Overall, 89.5% of patients characterized FS as not disturbing after 2 years.
Conclusions |
FS occurred with a steady and high prevalence after superficial parotidectomy. In particular, SCMMF did not lower the risk of FS.

• | A prospective multicenter-controlled trial is carried out. |
• | The prevalence of Frey's syndrome (FS) after superficial parotidectomy is high (45.1%). |
• | Interposition of the sternocleidomastoid flap could not diminish the prevalence of FS. |
• | The FS could be detected at 6 months after surgery in Minor's test. |
• | The affected sweating area increased continuously over the first 2 years after surgery. |
