    The distribution of the facial neurons that innervate several facial muscles was determined in the rabbit and the rat by examining the retrograde transport of horseradish peroxidase (HRP). The target muscles were musculus levator nasolabialis, m. levator labii superioris, m. zygomaticus, and m. buccinator pars buccalis, as well as m. parietoauricularis and m. depressor anguli oris in the rabbit and m. levator auricularis posterioris in the rat. Localization of the retrogradely labeled neurons within the ipsilateral facial nucleus was confirmed for all facial muscles examined. Our results showed that m. levator nasolabialis was innervated by neurons located in the dorsal subnucleus, while the motoneurons innervating m. buccinator pars buccalis were distributed within the dorsal part of the intermediate subnucleus of the facial nucleus in the both species. Localization of the labeled motoneurons innervating m. zygomaticus and m. levator labii superioris showed the difference in the distribution within the facial nucleus among the species. Neurons innervating m. parietoauricularis and m. levator auricularis posterioris were localized in somewhat different subregions of the medial subnucleus in these species. M. depressor anguli oris was innervated by the neurons distributed within the intermediate subnucleus of the facial nucleus in the rabbit. Thus, our findings revealed that there is speciesspecific motor innervation pattern in rabbits and rats, despite several movement of the face is supplied by the homologous facial muscles.

    We have been developing the pronunciation training system, in which visual instruction about the correct articulation are shown. These instructions are produced based on the formants of speech signal and show the shape of articulator to the learners. They work effectively, but more comprehensible instruction on how to move the articulator is required. We think that the facial muscles that move the articulator are useful to such the instruction. In this report, we attempt to construct lips movement model representing the relationship between the facial muscles activity and the lips movement and discuss the application of this model to pronunciation training.

    This research examined the feasibility of detecting sleepiness using expression features. About seven distances between facial feature points were set up as expression features based on the movement of expression muscles. The facial feature points were detected by pattern recognition using an Active Appearance Model (AAM). A sleeping experiment using a driving simulation task was conducted to measure the correlation between sleepiness levels and expression features, and then determine the feasibility of sleepiness detection.

    The present report describes an anomalous case of the risorius arising from the masseter tendon of an 83-year-old Japanese male used for student dissection practice. In this case, the risorius appeared to be almost of the typical type. However, one part of the risorius arose not from the fascia or skin over the masseter but directly from the masseter tendon itself. Such a situation is considered rare, since only one similar case has been reported by Eisler (1912).

    Anatomical observation wa s conducted on the facial musculature on each side of the face of 32 bodies (14 male,18 female) of Macacus cyclopsis (60 cases).
    The following findings were obtained. The facial muscles of primates do not have defin i te muscle fascia such as other skeletal muscles. The evolution of these muscle is reported to be the greatest (Huber) and complicated (Supli van and Osgoo d) at the glabella, the supraorbital region and about the mouth. Similar findings were noted in Macacus cyclopsis. All of these facial muscles are supplied by branches from N. facialis.
    1) M. orbicularis oculi This muscle may b e divided into Pars palpebralis, orbitalis, and peripheralis but the former two are unremarkable. Pars peripheralis is called M. malaris and if its Caput laterale has a bony attachment it should be called M. zygomaticus minor. The origin is by Caput mediale and Caput laterale but during its course, it interdigitates with the muscle fibers of M. levator labii sup. alaeque nasi and M. levator labii sup. to form a single muscular mass and runs to the upper lip.
    2) M. depressor supercilii This is a part of the fibers from the medial region of M. orbicularis oculi. They intermesh with the muscle fibers of M. frontalis, M. procerus and M. corrugator supercilii at between the brows and it is difficult to separate them.
    3) M. corrugator supe r cilii This muscle which should be considered a part of the deep fibers of M. orbicularis oculi interdigitates with the muscle fibers of M. depressor supercilii and M. frontalis.
    4) M. procerus This is an unpaired muscle formed by the union of M. levator labii sup. alaeque nasi on each side. This muscle is ill-defined due to the interdigitation of muscle fibers.

    The present study investigated the imaging features of odontogenic cutaneous sinus tract. CT and MR images of 12 patients with odontogenic cutaneous sinus tract were retrospectively investigated. The sinus tracts originated at mandibular teeth in 10 patients, and in the maxilla in only two patients. In patients with infection of mandibular teeth, the imaging features were classified into three types with reference to the location of the fistula and causal teeth. In 6 patients with Type I appearance, infections originated in the mandibular molar and a fistula was formed on the skin surface of the cheek piercing the platysma muscle between the depressor anguli oris and the masseter muscles on axial images. On coronal images, fistura was observed between the buccinator muscle and the attached portion of the palatysma muscle to the mandible. A patient showing Type II appearance had a periapical lesion of the mandibular canine and a fistula was formed between the mentalis and the depressor anguli oris muscles piercing the depressor labii inferioris muscle. In 3 Type III patients showing findings of extensive osteomyelitis of the mandible, sinus tracts opened near the inferior border of the mandible. The opening site of odontogenic cutaneous sinus tracts were restricted by their casual teeth and surrounding anatomical structures, especially by the masseter, depressor anguli oris, buccinator, mentalis and platysma muscles. CT and MR imaging appeared to be useful to depict these features.

    Bilateral, asymmetric anomalies of the anterior bellies of digastric muscles were observed during dissection of the submental region. Specifically, four extra muscle bundles were found between the anterior bellies of the digastric muscle. Although anomalies of the anterior bellies of digastric muscles are often observed, this complicated pattern of digastric anomalies has not been previously reported. Our findings and previous observations illustrate the morphogenetic complexity of the anterior belly of the digastric muscle derived from the first pharyngeal arch, which gives rise to jaw musculature such as the mylohyoid muscle.

    [Purpose] We analyzed the evaluation of facial motor paralysis employing Yanagihara's 40-point method for patients diagnosed with Bell's palsy, aiming to obtain some prognostic findings. [Subjects and Methods] The subjects were 33 patients diagnosed with Bell's palsy referred to us by the otorhinolaryngology outpatient clinic of our hospital. The onset age, timing of initiation of rehabilitation after onset, accessory symptoms, and facial motor paralysis were investigated. Facial motor paralysis was evaluated at the time of the first rehabilitation session and every 1-2 weeks thereafter. The scores were divided into upper and lower facial muscle groups. [Results] On the basis of outcome, patients were divided into 3 groups: the most favorable group, the favorable group, and the poor group. In the comparison of the 3 groups, the score of the first evaluation and the mean weekly score change were significantly greater in patients with favorable outcomes. In the comparison between the upper and lower facial muscles, the score for the upper facial muscles was significantly higher from the early phase, and the muscles recovered from paralysis more rapidly. [Conclusion] We evaluated facial motor paralysis of patients with peripheral facial palsy employing Yanagihara's method as a prognostic index, and obtained some prognostic findings.

    For the technical improvement for brass instrument players it is important to obtain the detailed control parameters for embouchure building. While many investigators have reported the preliminary data on the muscle behavior, the precise aspects are unrevealed so far. The purpose of the present paper is to study dynamic perioral muscle behavior of French horn players and to investigate their lip valve function by measuring the contact pressure on teeth buccal surface during playing. It was shown from the experimental results that the advanced players contracted depressor angulioris and levator angulioris especially for high tone playing. It is considered that the combined contraction by these muscles contributes to forming smaller lip aperture being suitable to produce higher tones. Inversely a strong contraction of m. buccinator, which is widely believed to work to give hard tension to player’s lip, was observed insignificantly in the advanced players.

    In order to better understand the pronunciation of the Chinese language, we investigated the movements of the oral cavity during pronunciation of the pinyinzimu sounds which were defined in 1958.
    We found from examination of palatogram and linguogram, and from the contact time of the tongue and palate that, more so than is the case with English or Japanese, it is necessary to make the tip of the tongue contact the palate lightly and for a longer duration in order to correctly pronounce the pinyinzimu sounds. Examination of the velocity in the mandibular incisor region revealed that it is greater during the open phase than the closed phase both for vowels and consonants. It was also found that the velocity during the closed phase is greater for vowels than for consonants.
    In addition, examination of the muscles associated with the oral cavity and the degree of opening indicated it was possible to determine the rest position by pronouncing the z, c, and s sounds which are made in the anterior of the mouth with the tip of the tongue (dental sounds).

    Face is considered as one of the most important item in emotion expression. Hence, facial paralysis can cause sever distraction in the patient's life ranging from various physical difficulties to psychological difficulties. Despite facial paralysis been fairly common, over the years only a very limited amount of effort has been put in to the development of supporting systems and it is also virtually zero in the robotics field. This paper describes a novel method of designing a thin, skinny, artificial muscle based robotic mask for facial paralyzed patients. The mask uses artificial muscles based on soft actuators as they can closely model natural muscles while producing silent actuations. Made to closely comply with human anatomy, the unit is developed as an external mask actuated automatically from EMG signal extracted from facial nerve. Testing were done on a healthy person using the 6 actuator single sided version of the mask : ExM1

    Asymmetry of facial movements in a newborn infant suggests seventh nerve palsy due to birth trauma or congenital malformation.
    An infant whose face appears asymmetrical at rest yet whose mouth is pulled downward to one side when crying is said to have an “Asymmetric crying facies”.
    In a 5-months-old baby boy.
    We noted the total absence of the right radius, the radial deviation of the wrist combined with curvature of the ulna, the shortness of the forearm, hypoplastic thumb, asymmetry of the auricles and when he cried, the left corner of the mouth drew left and downward.
    We have performed corrective surgery of the wrist deformity.

    Two experimental studies have been conducted in order to propose practice indexes for the improvement of the embouchure of French horn players, two experimental studies have been conducted. In both studies, the same task was performed by advanced and amateur French horn players. The first study investigated the activity, while performing the above-mentioned task, of the 5 facial muscles (levator labii superioris, zygomaticus major, depressor anguli oris, depressor labii inferioris, and risorius muscles) on the right side of the face by surface electromyography, and the facial movement on the left side of the face by attaching two markers above each muscle and using two high-speed cameras simultaneously. The results of the study showed that it is possible for the four markers around the lower lip to practice indexes. The second study evaluated whether the above-mentioned markers are appropriate as practice indexes using a 3-D tracking system and questionnaires. The results showed that both the advanced and the amateur players assessed that the markers were suitable as practice indexes for improving the embouchure. This set of approaches could be useful for selecting practice indexes and developing scientific practice methods not only for the French horn but also for other instruments and other fields.

     Lip defects may result from trauma and resection of malignant tumors. The lips not only provide function in feeding but are important for speech and the maintenance of facial expression. Reconstructive surgeons have to consider how to reconstruct these functions. In this article, we describe the surgical techniques of functional lip reconstruction. When the amount of resected tissue includes the entire lip mass, reconstruction by a free flap should be considered. The most commonly used free flap is a radial forearm. The forearm flap can be used by sensate flap with attaching a sensory nerve. Furthermore, a forearm flap is usually transferred along with the palmaris longus tendon, and this tendon has been used for the suspension of the lower lip by suture to the perioral skin, periosteum, or remnant orbicularis oris muscle. However, the palmaris longus tendon graft is a so-called static reconstruction, in order to avoid downward distortion of the lower lip. Recently, lip reconstruction using the gracilis muscle was reported. By suturing the obturator nerve to the facial nerve, the gracilis muscle can move voluntary and work as the orbicularis oris muscle. However, to cover the gracilis muscle, a skin graft or other skin flap should be transferred. The sensation of the lip and oral surface is also important for feeding. The combination of innervated gracilis muscle and sensate forearm flap allows for the reconstruction of the dynamic function and sensations of the lip.
