The lower third of the face
Published in Jani van Loghem, Calcium Hydroxylapatite Soft Tissue Fillers, 2020
The mentalis muscle may be treated with botulinum toxin to reduce dimpling and anterior projection. The treatment can be done prior to the CaHA application, in order to reduce risk of muscular contraction associated migration of the CaHA product. After projecting the chin, the entire infraoral area should be assessed and potentially adjusted by injecting additional CaHA or other fillers in the mental crease, pre-jowl sulcus, and/or marionette lines.

Chin projection can be accomplished with any of the HA fillers or with Radiesse. In our practice we prefer to use thicker HA fillers (i.e., Restylane Lyft or Voluma) to help with projection, and thinner HA fillers (i.e., Restylane Refyne and Juvederm Ultra) for addressing surface irregularities. Regardless of the goal, injection of the HA fillers can be done with either a serial puncture or linear threading technique with a cannula. For correction of “peau d’orange,” the HA filler is distributed evenly throughout the involved dermis. Clinically, this effect on surface contour was an incidental benefit realized in a patient undergoing injectable chin augmentation (Figure 9.13a and b). Prior to this, the primary treatment for the surface irregularity was Botox cosmetic injection (2–4 units) into the mentalis muscle. To maximize contour results, botulinum toxin and filler treatment can be combined, and a result lasting 9 months or longer can be obtained.

There are three muscles within this group: Mentalis: Runs inferiorly from the lower lip to its origin at the incisive fossa of the mandibleDepressor labii inferioris: Located superficial and lateral to mentalis with its origin laterally to mandibular surface between the symphysis menti and the mental foramenPlatysma: A thin sheet-like muscle stretching from its origin in the upper pectoral and deltoid fascia to its insertion in the lower lip
Stephanus Bisius (1724–1790) on mania and melancholy, and the disorder called plica polonica

Early in the eighteenth century, when there was great emphasis on new classification systems, Scottish physician William Cullen (1710–1790) referred to mania as insania universalis and classified it into four categories: mentalis, corporea, obscura, and symptomaticae (Cullen 1803). It was also during the eighteenth century that the perception of mania was rapidly changing. The causes of diseases were long thought to be disbalance among the humors, but forward-looking physicians were now becoming more focused on the bodily organs themselves. One of the newer theories involved vibrations, which Sir Isaac Newton (1642–1727) had been associating with perception and David Hartley (1705–1757) with memory. Mania, it was thought, might be due to nerves that were strung too tightly and had become overly sensitive, such that they vibrated too vigorously with even mild stimuli (Foucault 1965).

Unlike all the other widespread remote extracervical types of surgical access, the present type of surgical access is less traumatic due to the smaller area of detachment in the skin and muscle flap.26–29 The short muscles located over the thyroid gland lobe are not crosscut but are dislocated laterally with further fixation using the piercing ligature. The muscle structures within the chin area are also minimally traumatized—partial crosscutting is applied to the bundles of the mentalis muscle and the platysma muscles (in the area of mental protuberance). It is necessary to fit together and suture the incised bundles of the mentalis muscle to avoid the postoperative formation of lower lip ptosis. Creating an operating cavity in the neck area using the lifting method excludes the development of possible complications related to gas insufflation. In clinical practice one should expect the development of sensitivity disorders in the chin area and swelling of the anterior neck segments. Nakajo et al. reported that the swelling was resolved within several days and the sensitivity in the chin area within 6 months after the operation.21
