OBJECTIVES/HYPOTHESIS To examine drug-induced sleep endoscopy (DISE) findings in nonresponders to previous pharyngeal obstructive sleep apnea (OSA) surgery. STUDY DESIGN Cross-sectional. METHODS DISE using propofol for unconscious sedation was performed in nonresponders to previous OSA surgery (including palate surgery with or without tonsillectomy and possible other procedures). Nonrespond...

OBJECTIVES Compliance with continuous positive airway pressure (CPAP) treatment remains a primary concern for improving treatment outcomes of obstructive sleep apnea. There are few studies that have considered the role of upper airway anatomy on the compliance with CPAP. We hypothesized that upper airway anatomy would influence the compliance with CPAP. METHODS One hundred out of 161 consecut...

post-operative sore throat is one of the most common complications and complaints of patients after general anesthesia especially in operations that need endotracheal intubations. its causes are: size of endotracheal tube and type of its cuff, inadequate airway humidification, trauma during intubation and suctioning, high flow of inspiratory gases, surgical manipulation of airway and adjacent o...

EDITOR: We read with interest Drs Martin-Castro and Montero’s report on the use of the flexible laryngeal mask (FLMA) as an alternative to reinforced tracheal tube for upper chest, head and neck oncoplastic surgery [1]. We seek some clarifications from them with regard to the operations concerned. How many of the patients whose airways were managed with the FLMA had oro-pharyngeal malignancies?...

BODY: Introduction: Obstructive sleep apnea (OSA) is a common sleep disorder affecting both men and women in all ethnicities. It is well known that the primary cause of OSA is upper airway obstruction due to either anatomical or neurologic factors. The primary treatment modality for OSA is Continuous Positive Airway Pressure (CPAP). However, a significant proportion of patients diagnosed with O...

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...

Patients presenting for elective anaesthesia and surgery may be suffering with, or recovering from, a recent upper respiratory tract infection (URTI). It is a frequent clinical problem as to whether to postpone surgery in such patients as they may be more likely to suffer adverse respiratory events related to administration of general anaesthesia. Using dilute ammonia vapour as a chemical stimu...

Foreign bodies in upper airway may have various presentations and be life threatening. Leeches can attach to upper airway and cause serious problems. Herein we report a 55-year-old man with hemoptysis due to attachment of leech and explain our technique for its removal.
