Background: Frontal and glabellar muscle hyperactivity with consequent wrinkles are frequent complaints in plastic surgery. Treatment consists of impediment of related muscles; this can be achieved by application of botulinum toxin or surgery by means of classic coronal incision, endoscopic approach, transblepharoplasty access, or non-endoscopic limited approaches. This paper proposes an alternative of limited approach in which an incision is made on the central frontal scalp for treatment of the frontal and glabellar muscles. Methods: Between March 2009 and April 2010, 20 female patients were treated using a small incision on the frontal scalp, followed by dissection of frontal and glabellar regions. Muscles and supratrochlear and supraorbital nerve branches were identified; subsequently, frontal and glabellar muscle myotomy was performed. Results: All patients showed good results by frontal and glabellar muscle impediment during the evaluation period, with improvement in wrinkles and hyperactivity. Complications consisted of temporary paresthesia and pruritus in the central frontal region and scalp, in addition to recurrence of partial muscle contraction. Conclusions: The small incision approach on the central frontal scalp for treatment of frontal and glabellar muscles seems to be a good alternative to other surgical options due to its small size, inconspicuous scarring, and direct visualization of frontal and glabellar anatomic structures, allowing selective myotomy or myectomy.
