  • 현존하는 문헌에 의하면, 입술근육의 수축과 운동시간의 측면에서 영어의 자음을 경음-연음분류를 할 수 있는 음성학적 실증이 없는 것으로 나타나고 있다. 본 연구는 근육운동 측정기를 사용하여 영어와 한국어의 양순 정지음의 발화시 근육(orbicularis oris superior muscle)운동을 측정하였다. 영어의 강세음절에서는 기존의 주장과 같이 /p/와 /b/의 발화시 근육운동에 차이가 없거나 일관성이 없는 것으로 나타났으나, 무강세음절에는 기존 이론과 달리 근육운동수축에 있어서 /p/가 /b/에 비하여 통계학적으로 훨씬 큰 것으로 나타났다.(중략)

  • Objectives: Electroacupuncture has the effect of recovering paralytic nerves and muscles. To treat disproportional muscles of expression with electroacupuncture, it is essential that we know the correct point of paralytic muscle. Methods: We investigated 20 cases of patients with facial palsy sequelae. We measured nasolabial angles, checked grade of muscle palsy, and tested ENoG. Results: This study showed significant correlation between nasolabial angles with these muscle groups (zygomatic group I, zygomatic group II, orbicularis oris muscle). Conclusions: Disproportional facesare fixed by muscles of expression observed in facial palsy sequelae. We can treat muscular paralysis of these muscle groups with electroacupuncture for more complete recovery.

  • The purpose of this study was to determine EMG biofeedback training effect on the muscle activities in 3 unilateral facial palsy patients along with multiple baseline design across subjects. The auditory feedback about facial muscles (orbicularis oris, orbicularis oculi, frontalis) was provided with each patient during facial exercise training. Electromyographic (EMG) activity during maximal voluntary contraction and maximal compound muscle action potential (CMAP) amplitude elected by supramaximal electrical stimulation on facial nerve of facial muscles were measured pre- and post- EMG biofeedback training to evaluate motor learning. EMG activity during maximal voluntary contraction was increased after EMG biofeedback training and CMAP amplitude elected by supramaximal electrical stimulation was not changed in all subjects. The results indicate that EMG biofeedback training is useful method to improve motor learning of facial excercise training in unilateral facial palsy patients.

  • Objectives : The purpose of this study is to understand the anatomical basis of the facial muscles and to apply this knowledge on the clinical practice of facial acupuncture. Methods : We searched both contemporary and the latest literatures on the practical application of facial muscle anatomy on Facial Acupuncture. Conclusions : Facial Acupuncture improves skin tone, texture and wrinkling by assisting the circulation of Ki. It stimulates the facial muscles directly to undo the stagnation of the meridians. To practice Facial Acupuncture, thorough understanding of facial anatomy is required. In this study the muscles of the head and neck, appropriate depth and angle of acupuncture needle, etc. were reviewed. The upper facial muscles including frontalis, procerus, corrugator supercilii and orbicularis oculi, the mid facial muscles including auricularis, nasalis, levator labii superioris, zygomaticus and so on, and the lower facial muscles including orbicularis oris, depressor labii inferioris, depressor anguli oris, mentalis and platysma etc. were reviewed in this study. For safer and more effective use of Facial Acupuncture, further study on the objective outcome of the technique should be done.

  • Background: Rehabilitation of normal function and form is essential in cleft lip repair. In 2005, Dr. David M. Fisher introduced an innovative method, named "an anatomical subunit approximation technique" in unilateral cleft lip repair. According to this method, circumferential incision along the columella on cleft side of the medial flap is continued to the planned top of the Cupid's bow in straight manner, which runs parallel to the unaffected philtral ridge. Usually, small inlet incision is needed to lengthen the medial flap. On lateral flap, small triangle just above the cutaneous roll is used to prevent unesthetic shortening of upper lip. This allows better continuity of the Cupid's bow and ideal distribution of tension. Case presentation: As a modification to original method, orbicularis oris muscle overlapping suture is applied to make the elevated philtral ridge. Concomitant primary rhinoplasty also results in good esthetic outcome with symmetric nostrils and correction of alar web. As satisfactory results were obtained in three incomplete and one complete unilateral cleft lip patients, indicating Fisher's method can be useful in cleft lip surgery with functional and esthetic outcome. Conclusions: Clinically applied Fisher's method in unilateral cleft lip patients proved the effectiveness in improving the esthetic results with good symmetry. This method also applied with primary rhinoplasty.

  • Facial motor evoked potential (FMEP) by multi-pulse transcranial electrical stimulation (mpTES) can complement free-running electromyography (EMG) and direct facial nerve stimulation to predict the functional integrity of the facial nerve during cerebello-pontine angle (CPA) tumor surgery. The purpose of this paper is to examine the standardized test methods and the usefulness of FMEP as a predictor of facial nerve function and to minimize the incidence of facial paralysis as an aftereffect of surgery. TES was delivered through electrode Mz (cathode) - M3/M4 (anode), and extracranially direct distal facial muscle excitation was excluded by the absence of single pulse response (SPR) and by longer onset latency (more than 10 ms). FMEP from the orbicularis oris (o.oris) and the mentalis muscle simultaneously can improve the accuracy and success rate compared with FMEP from the o.oris alone. Using the methods described, we can effectively predict facial nerve outcomes immediately after surgery with a reduction of more than 50% of FMEP amplitude as a warning criterion. In conclusion, along with free-running EMG and direct facial nerve stimulation, FMEP is a useful method to reduce the incidence of facial paralysis as a sequela during CPA tumor surgery.

  • Reconstruction of the upper lateral lip subunit is challenging, and use of several classical local flaps have been previously reported. However, these methods have drawbacks such as visible scarring, anatomic distortion, and functional disability. To obtain satisfactory results, preservation of perioral function is important. We report a case of functional upper lip reconstruction after tumor resection using a reverse facial-submental artery island flap with a reinnervated anterior belly of the digastric muscle (ABDM) without sacrificing the perioral structure. A 73-year-old man presented with basal cell carcinoma on the left upper lip which was widely excised, including the orbicularis oris muscle. The remaining 4 cm × 3.5 cm defect was reconstructed using a reverse facial-submental artery island flap with ipsilateral ABDM. The motor nerve of the ABDM was sutured with the stump of the buccal branch of the ipsilateral facial nerve. The postoperative course was uneventful, and good functional and esthetic recovery were observed at 12-month follow-up. This procedure may be an alternative option for reconstruction of lateral upper lip defects.

  • Objective : The purpose of this study was to examine the effects of using Kinesiology Tape (KT) for drooling in children with cerebral palsy. Methods : A single-case experimental design with an ABA design was conducted. A total of 46 sessions were conducted, consisting of three baseline sessions (A), 40 intervention sessions (B), and three baseline sessions (A'). The Drooling Impact Scale (DIS) and the Interlabial Gap (IG) were measured before and after the KT intervention, and a Goal Attainment Scale (GAS) was assessed to determine whether there was any change in the target activity for each session. The KT intervention was attached to the orbicularis oris muscle. The KT intervention time was set as the time taken for dysphagia intervention and the actual meal time, for up to one hour a day, for a total of eight weeks. Results : The results of the study showed that the KT intervention had an effect on both the DIS and the IG, and that the GAS scale indicated that target activity increased with each session. Conclusion : These results indicate that the KT intervention can easily be applied to children with cerebral palsy who suffer from drooling, whether in clinical practice, by therapists, or caregivers, and that it can be used for various purposes.

  • The purpose of the present study was to investigate the difference of muscular activities of the tongue and lip muscles between anterior open-bite and normal occlusion during various function. Thirty eight subjects of 12.1-39.6 years were employed in this study : Eighteen subjects were anterior open-bites and tweenty subjects were normal occlusions. During rest position, maximum effort of lip sealing, command swallow of saliva and sucking & swallowing of juice, the electromyographic datas of the genioglossus, superior longitudinal muscle of tongue, upper and lower orbicularis oris were recorded and integrated with Medelec MS 25 electromyographic machine. Lateral cephalometric radiographs were taken on all subjects for the analysis of tongue posture and size. All data were recored and statistically processed. The findings of this study can be summerized as follows : 1. During the rest position, muscular activity of tongue was higher than that of lip muscle in open-bite, but no difference in normal occlusion group. 2. During the swallowing of juice, the activity of orbicularis oris was higher than that of genioglossus in open-bite. But the normal occusion was showed higher activity of tongue during the swallowing of juice. 3. The open-bite, compared to the normal occlusion, had higher value of tongue muscle activity during the rest position. 4. Compared to normal occlusion group, the open-bite had higher value of lip muscle activity during the sucking and swallowing of juice. 5. During the command swallow of saliva, the normal occlusion was showed harmonious swallowing pattern, but the open-bite showed much variation and disharmony in muscular contraction sequence, tended to absent of lip muscle activity. 6. At the lateral cephalometric radiographs, compared to the normal occlusion, the open-bite was showed lower tongue posture. But no difference was found in intermaxillary space. It is suggested that the open-bite, compared to the normal occlusion, had higher muscular activity of tongue during the rest position and various functions, showed lower tongue posture on the lateral cephalogram. In the development of anterior open-bite malocclusion, these factors may be an etiologic factor.

  • The buccal mucosa is an effevtive and versatile intraoral grafting material. For adequate reconst ruction of avulsed lip, restoration of natural appearance and adequate lip function should be done. We treated avulsed upper lip defect which had been affected underlying orbicularis oris muscle as well as vermilion border. We chose cheek mucosa for upper lip reconstruction and performed surgical correction of avulsed upper lip with pedicled buccal mucosal flap. The result was very good because of its superior color and texture matching to remaining yermilion tissue.
