tracheobronchopathia osteochondroplastica (to) is a rare disorder of large airways with unknown etiology which is characterized by cartilaginous and bony nodules lining the mucosa of the trachea and major bronchi. generally, it is benign and asymptomatic, but it may present with cough, exertional dyspnea and wheezing. it could therefore be mistaken with asthma and chronic obstructive pulmonary ...
Introduction: Two main causes of nasal airway obstruction and mouth breathing Consist: 1- anterior nasal obstruction is caused by obstruction in nasal cavity, 2- posterior (nasopharyngeal) obstruction is caused by adenoid enlargement and decreased nasopharyngeal airway. The purpose of this study was the comparison of nasopharyngeal cephalometric measurements between two groups of mouth breathin...
reinforced tubes are commonly used to minimize the opportunity of upper airway obstruction in patients at risk. there are a few reports of the airway obstruction resulted from kinked reinforced tubes. this report describes the obstruction of a reinforced tube in an adult patient who underwent tonsillectomy. under general anesthesia; an armoured endotracheal tube was inserted into the trachea un...
statement of problem: nasopharyngeal obstruction by adenoid enlargement is one of the main causes of mouth breathing. diagnostic indices of nasopharyngeal obstruction by lateral cephalometric radiography are controversial. purpose: the purpose of this study was to diagnose the nasopharyngeal obstruction by means of lateral cephalometric radiography. materials and methods: in this research two g...
introduction: septal deviation is the chief cause of chronic nasal obstruction. in order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. this study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery. ...
Introduction: Adenoid hypertrophy is associated with high morbidity rate in children. Although surgical treatment is indicated in severe cases, but there are evidences that some medical interventions are effective in improvement. This study was conducted to evaluate the effectiveness of corticosteroid nasal spray on reduction of airway obstruction due to adenoid hypertrophy. Methods: In a clini...
abstract acute upper airway obstruction (uao) is a life threatening complication that is well recognized after carotid endarterectomy, thyroidectomy and pharyngeal area intervention. it is not widely acknowledged that airway obstruction can occur after cervical spinal fusion surgery which was first described in 1955. there are a number of common postoperative problems which may become apparent ...
Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...
background and objective: numerous anatomical abnormalities or pathological conditions can cause upper airway obstruction in obstructive sleep apnea syndrome (osas). muller’s maneuver (mm) is one of diagnostic modalities investigating the obstruction site in patients with osas. this study aimed to investigate the obstruction sites of patients with osas based on mm. materials and methods: this w...
Background: Primary schwannoma of trachea and bronchus is very rare and can cause the same signs and symptoms as asthma, including airway-obstruction. Case Report: We introduce a 17 years-old girl with left bronchus schwannoma who was under treatment with the primary diagnosis of asthma and allergy. Bronchoscope intervention showed a pedicular tumor in left bronchus which protruded from the...
