Abstract Introduction: The objective of this study was to clarify the anatomy of the narial and labial musculatures of the one-humped camel (Camelus dromedarius) and their nerve supply. Materials and Methods: Sixteen head specimens from adult and symptomatically healthy camels of both sexes were used. The muscles of the nostrils and lips were carefully dissected and illustrated to demonstrate their origin, insertion and relations. The nerves in this area were also dissected to show their branches and distribution. Results: The dissection of these regions revealed that their muscles were arranged in three layers; the superficial layer included M. dilator naris apicalis, M. dilator naris medialis and M. levator nasolabialis, the middle layer was formed of maxillo-labial group of muscles (M. levator labii superioris, M. dilator naris lateralis and M. depressor labii superioris) and the deep layer was formed by M. lateralis nasi. Moreover, the lips had M. orbicularis oris, M. incisivus superioris, M. incisivus inferioris and M. mentalis, however, the M. depressor labii inferioris was absent in the animal under investigation. The muscles of nostrils and lips were innervated by N. trigeminus (V) and N. facialis (VII). Conclusion: The arrangement of the narial and labial muscles is unique and may relate to its living conditions of frequent sand-storms and direct sun rays, where the camel is the only domesticated animal known for its ability to close its nostril.

Introduction: Botulinum toxin, primarily known for its use in cosmetic surgery, is also used for therapeutic purposes in many medical fields. It works as a muscle relaxant and inhibits glandular secretions. In the orofacial sphere, the use of this toxin is proposed in particular for disabling myofascial pain and aberrant salivary disorders. Methodology: A critical analysis of the literature, based on PUBMED data, concerning the orofacial indications of botulinum toxin was carried out. Results: The literature is abundant regarding the therapeutic interest of this toxin for several oral pathologies, but scientific merits vary markedly from one indication to another. Discussion: The musculorelaxant and antisecretory action of this toxin appears to be demonstrated in the case of bruxism, limitation of the mouth opening and in hypersialorrhea. On the other hand, its medical benefit is still not supported by scientific evidence for masseter hypertrophy, tonicity of the levator labii superioris muscles, sialocele fistulae and Frey's syndrome. Conclusion: Additional high-level studies, unbiased, randomized controlled trials, are required to eliminate the uncertainties that persist about the clinical impact of botulinum toxin and to justify the development of recommendations for good practice valid and credible.

Gummy Smile

The harmony of the smile depends not only on the dentition, but also on the gum tissue, which excessively exposed can negatively affect aesthetics of the smile. Exposure of a small amount of gum during a smile is acceptable however a smile in which the exposure of the gum is more than 2 mm is considered an aesthetic defect called gummy smile. Among the causes of gingival smile listed are: shortened or hyperactive upper lip muscles (levator labii superioris, levator labii superioris alaeque nasi, zygomatic minor muscles), vertical maxillary excess, extrusion of alveolar ridges, altered passive eruption. In the case of hyperactive upper lip muscles, botulinum toxin can be used — this procedure was used in the described cases, and the effects were assessed using the FotoMedicus system and measurements of gingival exposure. In first case Bocouture botulinum toxin was administered on both sides, 4 units bilaterally in the levator labii superioris muscle and 2 units into levator anguli oris muscle. In total, 12 units were given. During the follow‑up the patient reported the start of the effect from the 5th day after the supply with the maximum effect after 12 days. A 6 mm correction of gummy smile was achieved. In the second case 4 units of botulinum toxin were applicated bilaterally into levator labii superioris alaeque nasi muscle. A 3 mm correction of gummy smile was achieved. The aesthetics of the face in a smile definitely improved in both men.

Mimetic Muscles

ABSTRACTWe display a detailed description of mimetic muscles in extinct human species, framed in comparative and phylogenetic contexts. Using known facial landmarks, we assessed the arrangement of muscles of facial expression in Homo sapiens, neanderthalensis, erectus, heidelbergensis and ergaster. In modern humans, several perioral muscles are proportionally smaller in size (levator labii superioris, zygomaticus minor, zygomaticus major and triangularis) and/or located more medially (levator labii superioris, zygomaticus minor and quadratus labii inferioris) than in other human species. As mimetic musculature is examined in the most ancient specimens up to the most recent, there is a general trend towards an increase in size of corrugator supercillii and triangularis. Homo ergaster’s mimetic musculature closely resembles modern Homo, both in size and in location; furthermore, Homo erectus and Homo neanderthalensis share many muscular features. The extinct human species had an elaborate and highly graded facial communication system, but it remained qualitatively different from that reported in modern Homo. Compared with other human species, Homo sapiens clearly exhibits a lower degree of facial expression, possibly correlated with more sophisticated social behaviours and with enhanced speech capabilities. The presence of anatomical variation among species of the genus Homo raises important questions about the possible taxonomic value of mimetic muscles.
