PURPOSE: With the aim of implementing good projection of the three-dimensional frame (auriculo-cephalic angle) and maintaining projection, a significant issue during the stage of auricular elevation for avoiding the potential for dislodging the cartilage blocks remains. Herein we present an innovative and technically simple method of transcutaneous fixation of the costal cartilage block during the stage of auricular elevation. MATERIALS AND METHODS: After elevation of ear frame from the basement, two suspension stitches on the surface of the elevated ear were used to fix the embedding cartilage block into the auriculo-cephalic sulcus at the upper (bifurcation point of the anti-helix where the inferior and superior crus meet to form the triangular fossa) and lower (projection point of the concha wall, parallel to the level of the tragus) ones...

BACKGROUND: Electrical stimulation of the auricular branch of the vagus nerve (ABVN) via transcutaneous auricular vagus nerve stimulation (taVNS) may influence afferent vagal networks. There have been 5 prior taVNS/fMRI studies, with inconsistent findings due to variability in stimulation targets and parameters. OBJECTIVE: We developed a taVNS/fMRI system to enable concurrent electrical stimulation and fMRI acquisition to compare the effects of taVNS in relation to control stimulation...

BACKGROUND: In the malar region, the SMAS flap can be thin and tear easily, making it difficult to securely fix it. And the surgical anatomy of the region may be unclear and confusing. The authors performed an anatomical study on the location of the lateral margin of the orbicularis oculi muscle (OOM) and the origin of the zygomaticus major muscle (ZMM) when using a high-SMAS facelift with finger-assisted spaces dissection technique, which included elevation of the SMAS flap with OOM...

PURPOSE: The recommendation issued by the American Academy of Pediatrics in the early 1990s to position infants on their back during sleep to prevent sudden infant death syndrome (SIDS) has dramatically reduced the number of deaths due to SIDS but has also markedly increased the prevalence of positional skull deformation in infants. Deformation of the base of the skull occurs predominantly in very severe deformational plagiocephaly and is accompanied by facial asymmetry, as well as an altered ear position, called ear shift...

Aceria salsolae (Acari: Eriophyidae) is being evaluated as a candidate biological control agent of Russian thistle (Salsola tragus, Chenopodiaceae), a major invasive weed of rangelands and dryland crops in the western USA. Prior laboratory host range testing under artificial lighting indicated reproduction on non-native Bassia hyssopifolia and on a native plant, Suaeda calceoliformis. However, in field tests in the native range, mite populations released on these 'nontarget' plants remained low. We hypothesized that UV-A light, which can affect behavior of tetranychid mites, would affect populations of the eriophyid A...

What is the topic of this review? This review briefly considers what modulates sympathetic nerve activity and how it may change as we age or in pathological conditions. It then focuses on transcutaneous vagus nerve stimulation, a method of neuromodulation in autonomic cardiovascular control. What advances does it highlight? The review considers the pathways involved in eliciting the changes in autonomic balance seen with transcutaneous vagus nerve stimulation in relationship to other neuromodulatory techniques...

BACKGROUND: Cerebral perfusion pressure (CPP) is a key parameter in management of brain injury with suspected impaired cerebral autoregulation. CPP is calculated by subtracting intracranial pressure (ICP) from mean arterial pressure (MAP). Despite consensus on importance of CPP monitoring, substantial variations exist on anatomical reference points used to measure arterial MAP when calculating CPP. This study aimed to identify differences in CPP values based on measurement location when using phlebostatic axis (PA) or tragus (Tg) as anatomical reference points...

BACKGROUND: The mechanisms of atrial fibrillation (AF) induced by obstructive sleep apnea (OSA) are not completely understood. This study investigated the roles of the intrinsic and extrinsic cardiac autonomic nervous system in OSA-induced AF and provided noninvasive autonomic nervous modulation for the suppression of OSA-induced AF by using low-level transcutaneous electrical stimulation (LL-TS) of the auricular branch of the vagus nerve at the tragus. METHODS AND RESULTS: Eighteen dogs received tracheostomy under general anesthesia and were randomly divided into 3 groups: the OSA group (OSA was simulated via clamping of the endotracheal tube at end expiration for 1...

OBJECTIVES: The aim of this study was to investigate whether low-level tragus stimulation (LL-TS) treatment could reduce myocardial ischemia-reperfusion injury in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: The authors' previous studies suggested that LL-TS could reduce the size of myocardial injury induced by ischemia. METHODS: Patients who presented with STEMI within 12 h of symptom onset, treated with primary percutaneous coronary intervention, were randomized to the LL-TS group (n = 47) or the control group (with sham stimulation [n = 48])...

Forward head posture has been evaluated mostly by visual observation or simple non-invasive measurements without a standardized evaluation method or protocol. In this experimental study, the reliability of existing forward head-posture measurement methods was evaluated by computing the intra-class correlation coefficients of three different head-position variables (two horizontal gap variables and one head-orientation variable) in seven different posture conditions from 20 asymptomatic participants. The position variables of the head were measured three times using a three-dimensional motion capture system while sitting comfortably, sitting with the back straight, standing comfortably, standing with the back straight, walking at 4 and 6km/h on a treadmill, and running at 8km/h on a treadmill...

BACKGROUND: Hyperkyphosis is associated with physical impairments, activity limitations, and reduced quality of life. Therefore, a simple, reliable, responsive, and valid clinical measure of dorsal kyphosis would be valuable to clinicians. OBJECTIVE: To describe a novel procedure for measuring kyphotic curvature-the inclinometric kyphosis measure (IKM)-and provide an estimation of reliability, responsiveness, and validity. METHODS: During 2 sessions spaced days apart, we used a bubble inclinometer to measure dorsal kyphosis in 68 patients receiving outpatient physical therapy...

Often cited reliability test on video superimposition method integrated scaling face-images in relation to skull-images, tragus-auditory meatus relationship in addition to exocanthion-Whitnall's tubercle relationship when orientating the skull-image and wipe mode imaging in addition to mix mode imaging when obtaining skull-face image overlay and evaluating the goodness of match. However, a report that found higher false positive matches in computer assisted superimposition method transited from the above foundational concepts and relied on images of unspecified sizes that are lesser than 'life-size', frontal plane landmarks in the skull- and face- images alone for orientating the skull-image and mix images alone for evaluating the goodness of match...

Background Benefits of cervical non-invasive vagus nerve stimulation (nVNS) devices have been shown in episodic cluster headache and preliminarily suggested in migraine, but direct evidence of vagus nerve activation using such devices is lacking. Vagal somatosensory evoked potentials (vSEPs) associated with vagal afferent activation have been reported for invasive vagus nerve stimulation (iVNS) and non-invasive auricular vagal stimulation. Here, we aimed to show and characterise vSEPs for cervical nVNS. Methods vSEPs were recorded for 12 healthy volunteers who received nVNS over the cervical vagus nerve, bipolar electrode/DS7A stimulation over the inner tragus, and nVNS over the sternocleidomastoid (SCM) muscle...
