Stridor causing respiratory failure is an ENT and anaesthetic emergency requiring prompt management to secure a clear airway. We describe a case of subacute partial upper airway obstruction due to a large laryngeal carcinoma in an 81-year-old male resulting in respiratory failure. The patient became apnoeic after gaseous induction of general anaesthesia, and after two failed intubation attempts an emergency transtracheal airway catheter was placed by the surgeon under direct vision below the cricothyroid membrane, as this had tumour involvement. The patient was subsequently manually jet-ventilated with ease until a formal tracheostomy was made. Where difficulties with tracheal anatomy are encountered due to the presence of pathology, the insertion of a temporary airway catheter for jet ventilation by the surgeon can buy valuable time and be life-saving.

Stridor is the sound caused by abnormal air passage into the lungs and can exist in different degrees and be caused by obstruction located anywhere in the extra-thoracic (nose, pharynx, larynx, trachea) or intra-thoracic airway (tracheobronchial tree). Stridor may be congenital or acquired, acute, intermittent or chronic. Laryngotracheal inflammation (croup) is the most common cause of acute stridor. Laryngotracheomalacia is the most common cause of congenital, chronic stridor. Stridor is a clinical sign and not a diagnosis. The golden standard in the workup of stridor is an upper and lower airway endoscopy under general anaesthesia. Endoscopic examination under general anaesthesia requires a multidisciplinary approach and close cooperation between anaesthesiologist, paediatrician, ENT surgeon and nursing staff. Following this procedure, a place in the intensive care unit should be available for those cases presenting with stridor in which a definite diagnosis could not yet be established. Although important, pre-endoscopy assessment including history, physical examination and radiological examination, is only a guide to the type and degree of pathology found during endoscopy. About 1 out of 10 infants are found to have lesions in more than one anatomical site of the upper aerodigestive tract.

Always ask about hoarseness and quality of voice in a history of any child presenting with cough or asthma-like symptoms. Children presenting with what appears to be an acute onset of hoarseness, without any physical signs of airways obstruction, should be reviewed after two weeks. If there is chronic hoarseness, referral to an ENT specialist should be considered with a view to laryngoscopy. If the child develops clinical signs of acute airway obstruction such as stridor or respiratory distress, prompt paediatric review is indicated. When referring, it is important to emphasise whether or not there is chronic hoarseness in order to differentiate the diagnosis from croup. Juvenile Laryngeal Papillomatosis may present with cough, pneumonia, dysphagia, or stridor, as well as hoarseness. These patients are often misdiagnosed as having asthma or allergies.

Idiopathic laryngeal spasm (ILS) is an uncommon disorder characterised by brief episodes of stridor, occurring at any time. Subsequent outpatient ENT examination is normal. These episodes cause considerable anxiety for both patient and physician. Little is known about the initiating event(s) in this condition or the long-term outcome. Using a combination of telephone and postal questionnaires with case note review, we have reviewed a cohort of 21 patients with this diagnosis managed by the senior author over the last 15 years. None of the 19 patients who responded were worse; 13 (68%) described improvement or complete resolution of symptoms. ILS is difficult to classify in the spectrum of vocal cord disorders, but appears distinct to those previously described. The condition responds well to a conservative management approach of reassurance and counselling.

The chondrosarcoma of the larynx is an exceptionally rare tumour. It appears mainly in white men in their 7th decade. The most significant clinical manifestation is hoarseness accompanied at times by stridor. It involves mainly the cricoid cartilage and the treatment of choice is surgical excision. A case of a large tumour of the cricoid cartilage is described. The diagnostic work-up consisted of two minor operations for biopsies and an MRI scan prior to the patient being treated with total laryngectomy.

A 51-year-old woman presented with a sore throat, hoarseness and difficulty in swallowing. On physical examination she was found to have stridor. Laryngoscopy revealed a subglottal stenosis. Infection was thought to be the cause but this was not confirmed by sputum or laryngeal cultures. Because of the clinical course and the presence of antineutrophil cytoplasmic proteinase-3 antibodies, Wegener's granulomatosis was diagnosed. Immunosuppressive therapy led to improvement. At 4-year follow-up the patient had scleritis but no ENT problems. Wegener's granulomatosis should always be considered in a patient with a subglottal stenosis; it can be the first symptom of this disease.

Foregut duplication cysts are rare congenital anomalies of enteric origin. The diagnosis is usually made in infancy. We report the unusual case of a 71-year-old female presenting to the ENT department with shortness of breath and stridor due to an oesophageal reduplication cyst. The presentation, diagnosis and management of this potential pitfall for the unwary are outlined.

Since about a decade cuffed intubation is becoming more popular in pediatric anesthesia. Studies supporting cuffed intubation compared cuffed and uncuffed intubation by using stridor as main outcome measure after extubation. No differentiations were made between benign (oedema) and severe (ulceration of mucosa) lesions. Stridor was considered to represent all relevant injuries. Far reaching conclusions for daily practice were drawn from these studies. Pediatric endoscopists and - ENT-surgeons with extensive experience in this field have warned against this opinion because significant injury of the airway is not always accompanied by stridor! The symptom of stridor might develop weeks and months after injury when silent ulcerations of the mucosa retract to significant stenosis. Only endoscopy can evidently detect all airway injuries. Studies describing airway injury by endoscopic control are urgently needed to find the best way of preventing airway injury by intubation.

Stridor is the sound caused by abnormal air passage during breathing. The cause of stridor can be located anywhere in extrathoracic airway (nose, pharynx, larynx, and trachea) or the intrathoracic airway (tracheobronchial tree). Stridor may be acute (caused by inflammation/infection or foreign body inhalation) or chronic. It may be congenital or acquired. Stridor is a sign from which the underlying cause must be sought; it is not a diagnosis. The role of the pediatrician faced with a child or infant with noisy breathing is: (1) to determine the severity or respiratory compromise and the need for immediate intervention (to prevent respiratory failure); (2) to decide based upon history and clinical examination whether a significant lesion is suspected and, in the latter situation, to refer the child to an ENT surgeon for an upper and lower airway endoscopy; (3) to understand the consequences and management strategies of the underlying lesion and to collaborate with colleagues from related disciplines for follow-up and subsequent management of the child.

This report describes stridor caused by a rare laryngeal tumour. The patient had presented to ENT with a midline neckmass and stridor of acute onset and diagnosed radiologically as a mass in the right lobe of thyroid gland in continuity with enhancing polypoidal mass in trachea at the same level. Total thyroidectomy along with the resection of the mass and tracheal ring was performed, trachea being anastomosed primarily. Histopathology reported it as a paraganglioma of the larynx. The patient has been followed-up for 5 years with no clinical or radiological recurrence of the tumour.
