Zenker's diverticulum (ZD), or pharyngeal pouch, is an anatomical defect characterised by herniation of the posterior pharyngeal wall through Killian's dehiscence, and may result in dysphagia and regurgitation. Multiple therapeutic modalities including surgery, rigid and flexible endoscopy have been developed to manage ZD. Although surgical management with open and endoscopically-assisted techniques have historically been the mainstay of ZD treatment, minimally invasive flexible endoscopic techniques, performed under conscious sedation, are increasingly favoured...

Introduction: Retropharyngeal space schwannomas are rare entities. About 20-45% of schwannomas occur in the head and neck region; however, they represent less than 1% of all head and neck tumors. Case Report: We present the case of a 36-year-old woman complaining of dysphagia caused by a large schwannoma arising in the posterior pharyngeal wall with remarkable reduction of the oropharyngeal space. The tumor was resected through a combined transoral and cervicotomic transmandibular approach due to its dimension...

Background: A Kloehn-type cervical headgear (CH) aims to correct skeletal jaw discrepancy in Class II children. A few studies have reported CH treatment effects on airway dimensions, but none of them have been randomized according to timing. Objectives: To evaluate related craniofacial structures and pharyngeal airway dimensions in children with a Class II occlusion treated with CH and randomized into early and late treatment groups. Trial design: Randomized, parallel-group, prospective controlled trial...

A small number of signaling pathways are used repeatedly during organogenesis, and they can have drastically different effects on the same population of cells depending on the embryonic stage. How cellular competence changes over developmental time is not well understood. Here we used Xenopus, mouse, and human pluripotent stem cells to investigate how the temporal sequence of Wnt, BMP, and retinoic acid (RA) signals regulates endoderm developmental competence and organ induction, focusing on respiratory fate...

The present study demonstrates the scale-eating behavior of a siluroid catfish, Pachypterus khavalchor, and the role of its oral structure and bacterial endosymbionts in shaping this lepidophagous habit. Scale-eating behavior in P. khavalchor was studied using a series of behavioral experiments. P. khavalchor was found to feed only on the scales of live fish and never of dead fish, even after 72h of starvation. It was nocturnal in habit and attacked all species that were used as prey. Attacking behavior showed extensive chasing of prey species followed by a powerful random strike at the flank or close to the caudal region in posterior oblique position...

Injuries to the hypoglossal and vagus nerves are the most commonly reported injuries during carotid endarterectomy. While unilateral single nerve injury is usually well tolerated, bilateral or combined nerve injuries can pose a serious threat to life. This study aims to increase awareness of the inferior pharyngeal vein, which usually passes posterior to the internal carotid artery but sometimes crosses anterior to it. Injury to either or both hypoglossal and vagus nerves can occur during control of unexpected haemorrhage from the torn and retracted edges of the inferior pharyngeal vein...

The external branch of the superior laryngeal nerve (EBSLN) innervates the cricothyroid muscle (CTM) to promote lengthening and thinning of the vocal fold, thus increasing voice pitch. The close relation with the superior thyroid vessels (STV) puts the EBSLN in risk every time the superior pole of the thyroid is dissected. It travels downward to innervate the CTM, lateral to the thyroid cartilage and to the inferior pharyngeal constrictor muscle (IPCM), being eventually covered by this muscle fibers as it approaches its entry point...

Occipitocervical (OC) fixation in a neck retraction position could be dangerous due to the risk of postoperative dysphagia. No previous study has demonstrated an association between the cervical posture change and cervical spine motion/angle during swallowing. So, we aimed to analyze the influence of neck posture on the cervical spine motion and angle change during swallowing.Thirty-seven asymptomatic volunteers were recruited for participation this study. A videoflurographic swallowing study was performed in the neutral and retracted neck posture...

The taxonomic position of the endemic Antarctic species Enchodeloides signyensis (Loof, 1975), gen. n., comb. n. (= Enchodelus signyensis Loof, 1975) is discussed on the basis of morphological study, including SEM, morphometric data, postembryonic observations, and sequence data of 18S rDNA and the D2-D3 expansion fragments of the large subunit rDNA. A number of characters such as the cuticle and stoma structures, including the presence of moderately developed cuticularised ring around the oral aperture, peculiarities of pharynx expansion, size and position of the posterior pair of pharyngeal nuclei, a less complex uterus, and the position of a posterior ventromedian supplement show that this species differs substantially from the other members of the genus Enchodelus...

A 77-year-old male patient presented with dysphonia. Endoscopic examination demonstrated a distortion of the posterior pharyngeal wall, which was pulsatile. The axial CT showed left internal carotid artery in a retropharyngeal location. An anomalous course of the carotid artery in the retropharyngeal space is an unusual finding that poses a risk of vascular injury during pharyngeal surgery and intubation. Such an anomaly may be congenital (incomplete descent of the third aortic arch) and may be more pronounced in older patients secondary to atherosclerosis and hypertension as occurred in our case noted here...
