Radiofrequency ablation of the cervical branch of the facial nerve was associated with improved platysmal banding in a cohort of individuals with noticeable platysmal banding.
The prospective, multicenter study included 19 patients accrued at two sites. Participants underwent ablation of the cervical branch of the facial nerve. Masked investigators compared baseline photography of participants with follow-up results at 1, 4, 12 and 24 weeks.
After the disqualification of one patient following ablation, results showed improved platysmal banding in 17 of 18 patients.
Adverse event information indicated no scarring, burns, ulceration, hypopigmentation or hyperpigmentation, according to the findings. Tender subcutaneous nodules occurred in three patients but were resolved 3 months after the procedure. Other short-term events included occasional postoperative fasciculations in one patient and a temporary inability to lower the ipsilateral lower lip in two patients.
Other findings indicated that no visible change was observed in 28% of the cohort, while 39% showed slight improvement, 22% reported moderate improvement and 11% reported marked improvement.
“This technique is an emerging alternative, nonsurgical option for neck rejuvenation that is relatively safe, with little downtime for the patient,” the researchers concluded. – by Rob Volansky
