Snoring and obstructive sleep apnoea (OSA) both exhibit multilevel upper airway obstruction. The Importance of evaluating the dynamics of the obstructing upper airway cannot be emphasised enough. Accurate assessment and evaluation of the upper airway could potentially lead to improved surgical and non-surgical treatment outcomes. Most of these patients would have undergone an ambulatory sleep s...

Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...

BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objective...

nasal mucosa has an extraordinary nerve supply with unique geometry that encompasses complex physiology. among these, side-specific predilections to the respiratory and autonomic centers are the interesting issues that have been raised about the consequences of the nasal irritations. the aim of the study was an evaluation of how intranasal stimulation influences lung mechanics and determines wh...

Pierre robin sequence is characterized by the triad of mandibular micrognathia, ‘U’ shaped cleft palate, and glossoptosis. Infants with this condition usually present airway obstruction feeding difficulties. This in turn leads to low weight nutritional deficiencies which might delay surgical intervention for same. case report describes a one-month-old infant Robin presenting difficulty nasal re...

Rhinophyma is a condition that can cause significant disfigurement as well as functional impairment of the nose. It results from hypertrophy and hyperplasia of the sebaceous glands and can be a manifestation of advanced staged rosacea. If left untreated, not only can it cause disfigurement, rhinophyma can also result in nasal airway obstruction by marked ptosis and collapse of the external nasa...

Drug induced sleep endoscopy is the most important investigation before surgical planning of obstructive sleep apnea patient. It is performed by artificially inducing sleep in a patient and performing nasal endoscopy in order to identify the site of upper airway obstruction. The most appropriate anesthetic agent would be that which induces sleep without any respiratory inhibition. Propofol has ...

Although there is abundant literature for both experimental and numerical studies of respiratory aerosol exposure in nasal airways, research efforts concentrating on diseased cavities undergoing pathological changes remain significantly less. This paper presents a comparative study pre- post-operative airway models based 3-year-old cavity model with severe nasopharynx obstruction due to the pre...
