Restauration du code barre labial par injection simultanée « one shot » toxine botulique-acide hyaluronique dans une même seringue

Abstract

The purpose of this technique is to offer patients wishing a labial restoration without morphological changes a simple, fast, discreet, comfortable, adaptable and reversible method by combining the two compounds most used in aesthetic medicine, botulinum toxin and hyaluronic acid. The originality of this combination is based on their mixing in the same syringe and their injection with cannula through a paracommissural approach which makes it possible to treat the entire upper lip in a very homogeneous manner. Botulinum toxin diffuses directly into the underlying muscle layer; hyaluronic acid allows to unfold the damaged cutaneous fan. The useful reciprocal dose of the two products remains intuitive; for starting barcodes the dose of botulinum toxin will be 8-10Speywood units (4Allergan units), for those already marked at rest 10-20Speywood units (4-8Allergan units); the hyaluronic acid will be chosen according to the depth of the wrinkles. We present a series of 63patients with an average age of 67years with a result deemed positive in 79% of cases. The incidents reported are generally due to excessive doses of botulinum toxin which can lead to the classic incidents of fluid leaks in this location (6%). The expected efficacy of the treatment depends on that of the components used (four to six months) but prolonged results have been regularly observed (up to 18months). All complementary resurfacing treatments have been discarded here since the aim pursued is that of a natural labial restoration allowing an immediate return to socio-professional activities.
