Hypopharyngeal geometry impact on air-induced loads on the supraglottis.

Exercise-induced laryngeal obstruction (EILO) describes paradoxical laryngeal closure during inspiration at high-intensity exercise. It is hypothesised that during intense activity, the air-induced loads on supraglottic walls overcome their internal stiffness, leading to the obstruction. Recent investigations have revealed that the air-induced loads on the supraglottic walls vary nonlinearly with increasing flow rate.

This was a prospective and cross-sectional study of 60 individuals with oral malignancies (OM) (20 each of tongue, epiglottis, and hard palate) studied at Malla Reddy Medical College and tertiary care hospitals in Hyderabad. Adults aged ≥ 18 years and diagnosed with oral cancer were included in the study.

Accuracy of Sonographic Airway Parameters in Difficult Laryngoscopy Prediction: A Prospective Observational Cohort Study from Central India.

Objective: Though airway ultrasonography (USG) is used to assess difficult laryngoscopy (DL), there is still ambiguity about approach followed and parameters assessed. There is need of a simple, stepwise sonographic assessment with clearly defined parameters for DL prediction. The primary objective of this study was to find diagnostic accuracy of sonographic parameters measured by a stepwise Airway-USG in DL prediction (DLP).

Congenital Absence of the Epiglottis in a 35 Years Old Patient.

Absent epiglottis is a rare reported anomaly in adults with unknown incidence. Most patients with absent epiglottis have presented with life-threatening symptoms of respiratory distress or severe aspiration in infancy or early childhood. We report a case of a 35 year old male patient with complete absence of epiglottis, presented with complaint of hoarseness of voice since birth.

Morphology and computed tomography of the larynx in the white-eared opossum (Didelphis albiventris).

The white-eared opossum (Didelphis albiventris) is a Neotropical marsupial that occurs in the Brazilian territory. The larynx is an important organ of vocalization in mammals, although, other laryngeal functions are more fundamental for survival of mammals than phonation. The anatomical knowledge of respiratory structures is pivotal for a better understanding of the species.

The morphometrical evaluation after uvulopalatopharyngoplasty.

Objectives: The aim of this study was to evaluate the efficacy of uvulopalatopharyngoplasty (UPPP) and the corresponding postoperative morphometrical changes.

Methods: Patients diagnosed with obstructive sleep apnea syndrome who complained of snoring and apnea were enrolled in this study. Pre- and postoperative tests, including CTs, pharyngeal volume (PV), cross-sectional area (CSA), and six-category morphometrical studies, were performed.

Comparative Histoanatomy of the Epiglottis and Pre-epiglottic Space of the Chimpanzee Larynx.

Objectives: Understanding of the evolution of the larynx clarifies the physiology and functional histoanatomy of the present-day human organ. Comparative histoanatomy of the epiglottis and pre-epiglottic space of the chimpanzee larynx (a hominid, phyletic closest relative of humans) was investigated.

Methods: Two normal adult chimpanzee larynges obtained from natural deaths were investigated.

Successful Surgical Excision of Retropharyngeal Plexiform Neurofibroma in a Non-neurofibromatosis Adult Male.

Plexiform neurofibromas are benign tumors that arise from neuronal cells and are commonly associated with neurofibromatosis type 1 (NF1) patients. However, the occurrence of plexiform neurofibromas in the pharyngeal region is extremely rare. In this particular case, we report the successful diagnosis of a retropharyngeal plexiform neurofibroma in an adult male patient without a history of neurofibromatosis.

Vaping-induced acute epiglottitis: a case report.

Background: E-cigarette use, or vaping, is an alternative nicotine delivery system that is becoming increasingly prevalent in adolescents and young adults. There is currently a lack of comprehensive research on the adverse effects of vaping on the upper airway. Acute epiglottitis is a potentially life-threatening condition that can lead to airway obstruction.

Epiglottic Hemangioma: A Rare Case of Hemoptysis in Adults.

Hemangiomas are benign slow growing vascular tumors of endothelial origin, commonly seen in young. Laryngeal hemangiomas are rare entities with varied clinical presentations depending upon their location and size. We hereby report a rare case of recurrent hemoptysis in a 65-year-old lady with epiglottic hemangioma.

[Effect of mouth breathing on upper airway structure in patients with obstructive sleep apnea].

To compare the changes of morphology of pharynx in patients with obstructive sleep apnea hypopnea syndrome （OSAHS） and healthy individuals during oral or nasal breathing, and explore the relevant influencing factors. Twenty-nine adult patients with OSAHS and 20 non-snoring controls underwent MRI to obtain upper airway structural measurements while the subjects were awake and during mouth breathing with a nasal clip.The following were analyzed.

Can functional septoturbinoplasty, with or without nasal valve suspension suture (FSTVS), alter the initial findings of drug-induced sleep endoscopy (DISE) in patients with obstructive sleep apnea syndrome (OSAS)?

Background: Drug-induced sleep endoscopy (DISE) is routinely performed to assess the upper airway collapse in patients with obstructive sleep apnea syndrome (OSAS). Its purpose is to identify cases of multilevel collapse, which helps to determine the appropriate surgical approach. The current proposal to analyze the functional septoturbinoplasty with or without nasal valve suspension suture (FSTVS) has the potential to change the original findings of DISE in OSAS patients who were initially planned for one-stage multilevel surgery based on the pre-FSTVS DISE results.
