Transoral endoscopy with narrow band imaging is useful for early detection of pharyngeal cancer.(1) The postcricoid area and the posterior wall of the hypopharynx, however, are still difficult to observe because they're anatomically closed.(2) Although the Valsalva maneuver with transnasal endoscopy has been reportedly useful for opening the closed area,(3) it is difficult with transoral endoscopy.

Lungs are specialized organs originated from the posterior pharyngeal cavity and considered as plesiomorphic for osteichthyans, as they are found in extant basal actinopterygians (i.e. Polypterus) and in all major groups of extant sarcopterygians. The presence of a vestigial lung in adult stages of the extant coelacanth Latimeria chalumnae is the result of allometric growth during ontogeny, in relation with long-time adaptation to deep water. Here, we present the first detailed histological and anatomical description of the lung of Latimeria chalumnae, providing new insights into its arrested differentiation in an air-breathing complex, mainly represented by the absence of pneumocytes and of compartmentalization in the latest ontogenetic stages...

INTRODUCTION: Velopharyngeal insufficiency (VPI) is usually managed, besides speech therapy, by performing a velopharyngoplasty. An alternative approach is autologous fat grafting (AFG) of the posterior pharyngeal wall. About 5% of the population has internal carotid arteries (ICA) with an aberrant course. This anatomic variation can be responsible for surgical difficulties while when performing a velopharyngoplasty, and therefore lead surgeons to only consider a speech reeducation of VPI...

Objectives: In some patients, obstructive sleep apnea (OSA) can be resolved with improvement in pharyngeal patency by sleeping lateral rather than supine, possibly as gravitational effects on the tongue are relieved. Here we tested the hypothesis that the improvement in pharyngeal patency depends on the anatomical structure causing collapse, with patients with tongue-related obstruction and epiglottic collapse exhibiting preferential improvements. Methods: Twenty-four OSA patients underwent upper airway endoscopy during natural sleep to determine the pharyngeal structure associated with obstruction, with simultaneous recordings of airflow and pharyngeal pressure...

Nasopharynx (NP) is anatomically difficult to explore adequately. The pharyngeal bursa (PB) is a recess lined with respiratory epithelium along the posterior wall of the nasopharynx between the longus capitis muscles. If the opening through which the bursa drains into the nasopharynx becomes obstructed, a Thornwaldt's cyst (TC) might develop. Small-sized cysts are mostly asymptomatic, whereas large-sized cysts may lead to various nasal and otologic symptoms depending on their localization. In this report, we present a 71-year-old case with a huge TC who presented to our clinic with the complaints of snoring, nasal obstruction, periodic halitosis, postnasal drip, headache, and hearing loss in the left ear and underwent total excision of the cyst through transnasal endoscopy...

BACKGROUND: Obstructive sleep apnea (OSA) in individuals with craniofacial anomalies can compromise airway and is a serious life-threatening condition. In many cases, tracheostomy is carried out as the treatment of choice. Distraction osteogenesis of the mandible as a treatment modality for OSA is very useful and may spare the need for tracheostomy or allow decannulation, yet controlling the vector of distraction is still a major challenge. We present a method for controlling the vector of distraction...

The pharynx, possessing gill slits and the endostyle, is a characteristic of chordates that is a complex of multiple tissues well organized along the anterior-posterior (AP) axis. Although Hox genes show AP coordinated expression in the pharyngeal endoderm, tissue specific roles of these factors for establishing the regional identities within this tissue is largely unknown. Here, we show that Hox1 is essential for the establishment of AP axial identity of the endostyle, a major structure of the pharyngeal endoderm, in the ascidian Ciona intestinalis We found that Hox1 knockout causes posterior to anterior transformation of the endostyle identity, and Hox1 represses Otx expression and anterior identity, and vice versa...

Submucous cleft palate (SMCP) is a relatively rare variant of the common pathology of cleft palate with specific anatomic and clinical features. Even though there are many surgical options defined previously to correct the SMCP, correction of the velopharyngeal insufficiency and obtaining ideal speech results remains as a challenge. The aim of this article was to compare the speech benefits of Furlow double opposing Z plasty and posterior pharyngeal flap operation combined with intravelar veloplasty for the correction of SMCP using objective assessment tools...

BACKGROUND: Among authors studying morphological determinants of the Obstructive Sleep Apnoea (OSA) controversies exist on the location of the narrowest area within the pharynx critical for development of obstruction. Those disagreements primarily revolve around differences between obese and nonobese OSA patients. Determination whether the location and size of the narrowest area within the pharynx differentiates the obese and nonobese OSA patients. MATERIALS AND METHODS: A population of 55 subjects was investigated after being diagnosed with OSA in the Polysomnography Laboratory of the Department and Clinic of Otolaryngology in the Medical University of Warsaw...

The aim of this study was to evaluate both the 2-dimensional (2D) and 3-dimensional (3D) configuration of the posterior airway space (PAS) in healthy 239 patients using cone-beam computed tomography (CBCT). In particular, we investigated the correlation between the 2D and 3D measurements in view of the potential impact on diagnosis of upper airway obstruction. The pharyngeal airway of each patient was studied at five levels: the level of the posterior nasal spine (PNS), the level of half-height of the PNS and the tip of the soft palate, the level of the tip of the soft palate, the level of the anterior-inferior point of the second vertebra, and at least the level of the top of the epiglottis...

Anterior cervical discectomy and fusion (ACDF) is a very common surgery performed globally. Although a few cases of expectorating screws or extrusion of screws into the gastrointestinal tract through esophageal perforations have previously been reported, there has not been a case reporting pharyngeal perforation and entire cervical construct extrusion in the literature to date. In this report the authors present the first case involving the extrusion of an entire cervical construct via a tear in the posterior pharyngeal wall...

Canonical Wnt/β-catenin (Wnt) signaling plays multiple conserved roles during fate specification of cardiac progenitors in developing vertebrate embryos. Although lineage analysis in ascidians and mice has indicated there is a close relationship between the cardiac second heart field (SHF) and pharyngeal muscle (PM) progenitors, the signals underlying directional fate decisions of the cells within the cardio-pharyngeal muscle field in vertebrates are not yet understood. Here, we examined the temporal requirements of Wnt signaling in cardiac and PM development...
