Abstract Background Lips are considered a key element of facial attractiveness due to their central position in the face and their elemental role in verbal and nonverbal communication. Objectives The authors sought to provide clinically relevant information on the 3-dimensional pathway of the superior and inferior labial arteries within the lips to increase safety during labial soft tissue filler injections. Methods The study enrolled 41 healthy volunteers with a mean age of 26.17 ± 9.6 years and a mean body mass index of 23.09 ± 2.3 kg/m2. Ultrasound imaging was performed at 6 different locations. The position of the labial arteries within the lips, depth of the arteries, cranio-caudal location of each artery in relation to the vermilion border, and diameter of the superior/inferior labial arteries were recorded. Results The most frequent location of both the superior and inferior labial arteries was the submucosal plane (58.5%) followed by intramuscular (36.2%) and subcutaneous (5.3%) planes. The depth of the superior labial artery in the upper lip was 5.6 ± 0.13 mm, whereas the depth of the inferior labial artery in the lower lip was 5.2 ± 0.14 mm. Both arteries were more frequently located within the red lip: upper lip (83% vs 18.7%) and lower lip (86.2% vs 13.8%). In the midline, the artery coursed within the red lip in all investigated volunteers. Conclusions Clinically, results of this study favor a superficial injection plane for lip volumization procedures. A perpendicular approach to the lip (coming from the cutaneous lip) might increase safety because the artery is located most frequently within the red lip.

Lifting Task

A case report is presented of an attempt to increase muscle activity during non-speech and speech activities through surface electromyographic feedback. The subject, a 25-year-old male, had a surgical anastomosis of the seventh cranial to the twelfth cranial nerve five years prior to the initiation of this therapy. The right side of the face was immobile. Frequency analogs of muscle action potentials from the right lower lip during pressing, retraction, eversion, and speech were presented to the subject. His task was to increase the frequency of the tone thereby increasing muscle activity. The subject made substantial improvement in the gestures listed above. Electrodes also were placed in various infraorbital positions for an upper lip lifting task. This gesture was unimproved. Pre- and posttherapy independence of facial gestures from conscious tongue contraction was found. Possible explanations were proposed for (1) increases of muscle activity in the lower lip, (2) lack of change of MAPs in the upper lip, (3) independence of the facial muscle activity from conscious tongue contraction, and (4) effectiveness of this feedback training.

The Circles of Prominence, A New Theory on Beauty: Ideal Distances in the Eyes, Nose, Ears and Lips. The Circles of Prominence (COP) theorizes that the width of the iris serves as an ideal for multiple distances and shapes within the face. We wanted to test if the iris width (IW) dictates: 1.) the aesthetic ideal distance between eyelid margin and bottom of the eyebrow; 2.) the aesthetic ideal width of the nasal bridge and tip; 3.) the aesthetic ideal height of the upper lip; 4.) the aesthetic ideal height of the lower lip; 5.) and the aesthetic ideal distance the ear extends from the side of the face. This was a subjective survey to test these distances to find the ideal. The data supports that the ideal distance for eyebrow height, nasal bridge & tip width, and lower lip height are all 1 IW as predicted by the COP. The ideal height of the upper lip was statistically found to be ½ IW. The ideal distance that the ear extends from the side of the face was split between ½ IW and 1. As predicted, the data supports the idea that the Iris width serves as the ideal distance or shape for many elements in the face.

Abstract Background Injecting soft tissue fillers into the deep plane of the forehead carries the risk of injection related visual compromise due to the specific course of the arterial vasculature. Objectives To investigate the 2- and 3-dimensional location of the change of plane of the deep branch of the supratrochlear and supraorbital artery, respectively. Methods A total of 50 patients (11 males and 39 females, mean age: 49.76 (13.8) years, mean body mass index of 22.53 (2.6) kg/m 2) were investigated with ultrasound imaging. The total thickness, and the distance of the arteries from the skin and bone surface were measured using a 15-7 MHz broadband compact linear array transducer. Results The deep branch of the supraorbital artery changed plane from deep to superficial to the frontalis muscle at a mean distance of 13 mm [range: 7.0 – 19.0] in males and at 14 mm [range: 4.0 – 24.0] in females and for the deep branch of the supratrochlear artery at a mean distance of 14 mm in males and females [range: 10.0 – 19.0 in males, 4.0 – 27.0 in females} when measured from the superior orbital rim. Conclusions Based on the ultrasound findings in this study, it seems that the supraperiosteal plane of the upper and lower forehead could be targeted during soft tissue filler injections as the deep branches of both the supraorbital and supratrochlear arteries do not travel within this plane. The superficial plane of the lower forehead, however, should be avoided due to the unpredictability and inconsistent presence of the central and paracentral arteries.

Lip provides an attractive and pleasing appearance to the face. Lip anomaly is by the presence of excess fold or redundant or tissue on side of the lip which is referred as double lip. It can be either congenital or acquired and unilateral or bilateral. Such rare entity can affect either upper lip or lower lip or both as seen in syndrome which can be easily diagnosed clinically and rarely reports were published on congenital double lip. During growth and development, the upper lip possesses an outer cutaneous zone often referred as pars and an inner zone which is known as pars which are the two transverse zones. The non-inflammatory labial mucous gland of the pars and unreasonable abundant tissue results in double lip. Treatment should be carried out by an excision of the and sub tissue, without involvement of the underlying muscle This article is a report of a 10 years old boy with this deformity who presented with the complaint of huge lips causing unaesthetic appearance of face and was surgically managed improving the appearance of the face aesthetically acceptable which in turn improves the confidence level of an individual.

Introduction: The success of orthodontic treatment is often associated with the improvement of facial appearance. Soft tissues of the nose, lips and chin are important factors in determining the beauty of the face. The aim of this study was to determine the facial profile of the Bataknese based on the proportion of soft tissue facial components such as nose, lips and chin. Materials and Methods: This research was an observational study with a cross-sectional design. The samples of this research consists of 48 Batak tribe students in FKG USU Medan. This research was carried out by using 48 lateral cephalometry obtained from Batak tribe students who fit the inclusion criteria.Determination of soft tissue facial profile was carried out with Skinazi method. Results: The mean proportion results obtained from the soft tissue facial components of the nose was 64.41%, upper lip 13.79%, lower lip 14.80% and chin 6.86%. The results showed soft tissue facial profile obtained descriptively from the Bataknese were highest in nose proportion followed by lower lip, upper lip and the smallest were chin proportion. Large proportion of the nose and small proportion of chin showed that facial profile of the Bataknese were convex. The results of t- test and Mann Whitney analysis of nose, upper lip, lower lip and chin proportion showed there were no difference between male and female (p>0.05). Conclusion(s): The findings of this research showed that the soft tissue facial profile based on nose, lips and chin propotions in male and female from Batak tribe were convex.

1. We have demonstrated recently that reversible, cooling-induced inactivation of the face primary somatosensory cortex (SI) severely impairs the successful performance of a tongue-protrusion task but has relatively minor effects on the performance of a biting task. In an attempt to establish a neuronal correlate for these different behavioral relations, the present study was initiated to document the mechanoreceptive field properties of a population of face SI neurons and their activity during the tongue-protrusion and biting tasks. 2. Within SI, the representation of the face was found immediately lateral to that of the hand, and there was a clear somatotopic pattern of organization within face SI: the periorbital or nose region was located most medially in the face SI, then followed laterally in sequence the representation of the upper lip, lower lip, and intraoral area. A mechanoreceptive field (RF) was identified for 253 neurons, which included 162 “lip RF” neurons receiving mechanosensitive afferent inputs from the upper lip, lower lip, or both; 72 “tongue RF” neurons that received mechanosensitive afferent inputs from the tongue; 11 “periodontium RF” neurons receiving periodontal inputs; and 8 neurons that received inputs from other orofacial regions. 3. Nearly all (249/253) of the face SI neurons responded to light tactile stimuli, and most of them received contralateral inputs (78%) and showed a rapidly adapting (RA) response to tactile stimulation (82%). There was no significant difference in the ratio of slowly adapting (SA) to RA neurons in areas 3b and 1. 4. For 193 neurons studied in one or both of the orofacial tasks, 113 were found, on the basis of histological reconstruction, to be distributed in area 1, 61 in area 3b, and 19 in area 2. 5. The firing rate of most tongue RF (79% of 56) neurons and lip RF (60% of 93) neurons tested was significantly altered during the tongue-protrusion task. Only some (14% of 36 tongue RF neurons and 34% of the 92 lip RF neurons tested) showed a significant change in firing rate during the biting task. Three of 7 periodontium RF neurons studied in the tongue-protrusion task altered their firing rate and 5 of 10 altered their firing rate during the biting task. 6. Most of the 116 face SI neurons studied during both tasks exhibited a preferential relation to the tongue-protrusion task as distinct from the biting task, and none showed task-related activity during the biting task only.(ABSTRACT TRUNCATED AT 400 WORDS)

In this article, a system to detect driver drowsiness and distraction based on image sensing technique is created. With a camera used to observe the face of driver, the image processing system embedded in the Raspberry Pi 3 Kit will generate a warning sound when the driver shows drowsiness based on the eye-closed state or a yawn. To detect the closed eye state, we use the ratio of the distance between the eyelids and the ratio of the distance between the upper lip and the lower lip when yawning. A trained data set to extract 68 facial features and “frontal face detectors” in Dlib are utilized to determine the eyes and mouth positions needed to carry out identification. Experimental data from the tests of the system on Vietnamese volunteers in our University laboratory show that the system can detect at realtime the common driver states of “Normal”, “Close eyes”, “Yawn” or “Distraction”

INTRODUCTION: A female patient aged 12 years and 2 months had molars and canines in Class II relationship, severe overjet (12 mm), deep overbite (100%), excessive retroclination and extrusion of the lower incisors, upper incisor proclination, with mild midline diastema. Both dental arches appeared constricted and a lower arch discrepancy of less than -6.5 mm. Facially, she had a significant upper incisors display at rest, interposition and eversion of the lower lip, acute nasolabial angle and convex profile. OBJECTIVE: To report a clinical case consisting of Angle Class I malocclusion with deep overbite and overjet in addition to severe crowding treated with a conservative approach. METHODS: Treatment consisted of slight retraction of the upper incisors and intrusion and protrusion of the lower incisors until all crowding was eliminated. RESULTS: Adequate overbite and overjet were achieved while maintaining the Angle Class I canine and molar relationships and coincident midlines. The facial features were improved, with the emergence of a slightly convex profile and lip competence, achieved through a slight retraction of the upper lip and protrusion of the lower lip, while improving the nasolabial and mentolabial sulcus. CONCLUSIONS: This conservative approach with no extractions proved effective and resulted in a significant improvement of the occlusal relationship as well as in the patient's dental and facial aesthetics.

Inferior-superior displacements of the upper lip, lower lip, and jaw were transduced with a strain-gauge system in 4 normal-speaking adults. Movements of the upper and lower lips were compared across conditions in which the jaw was free to move and when bite blocks were used to fix the jaw at four different vertical positions. As jaw-open position was increased with the bite blocks, it was found that: (a) Positions of both lips changed for bilabial closure, but the closing movements did not usually maintain consistent proportions between lips across different bite-block sizes; (b) although the lips maintained fairly consistent maximum interlabial opening across many conditions, this opening was reduced in the small bite-block conditions; and (c) in a few cases there was an increase in the duration of lip-closing movements, but these were small and inconsistent. The findings are discussed relative to possible organizational systems that would produce the observed interactions among speech articulators.
