Lamm introduced fibre-optic imaging in 1930s 1 . In the following decades it has been utilized in otolaryngology as an alternative to indirect mirror laryngoscopy. In its present form it allows for image capture and video recording when connected to a camera, it also allows for manoeuvring around anatomical structures due to its flexibility and articulation. It now forms an essential part of any head and neck examination especially when assessing for suspected cancer. This article is protected by copyright...

OBJECTIVES: Positron emission tomography-computed tomography with fluorine-18 fluorodeoxy-D-glucose has a major role in the investigation of head and neck cancers. Fluorine-18 fluorodeoxy-D-glucose is not a tumour-specific tracer and can also accumulate in benign pathology. Therefore, positron emission tomography-computed tomography scan interpretation difficulties are common in the head and neck, which can produce false-positive results. This study aimed to investigate patients detected as having abnormal vocal fold uptake on fluorine-18 fluorodeoxy-D-glucose positron emission tomography-computed tomography...

Salil Sood, Ian Street, Adam Donne
Hoarseness or dysphonia are terms used to describe a change in the quality of the voice. The voice quality can be raspy, breathy, strained, fatigued, rough, tremulous or weak. There may be a change in pitch, restriction of range, voice breaks, decreased projection, or abnormal resonance. It is important to remember that a voice disorder is not a disease in itself but rather a presentation of an underlying pathology. Clinicians' knowledge of paediatric hoarseness is limited as it can be difficult to examine children using fibreoptic laryngoscopy and the child may not comprehend the need for detailed examination...

Prasanna Kumar Saravanam, Vinoth Manimaran
The incidence of congenital stridor is on rise due to improved neonate and infant survival rate. The gold standard investigation for evaluation of stridor is rigid laryngotracheobronchoscopy, but this is invasive and requires general anesthesia. Flexible fibreoptic laryngoscopy, a relatively simple and less invasive procedure can be done under topical anaesthesia for evaluation of stridor. In this study, we have presented our experience of flexible laryngoscopy in children with congenital stridor, their results and management...

BACKGROUND: Postthyroidectomy voice disorders can occur without any recurrent laryngeal nerve injury, and probably are the most frequent complication after thyroidectomy. We report the long-term voice quality outcomes after total thyroidectomy without vocal cord palsy using a simple self-assessment tool: the voice handicap index self-questionnaire. METHODS: This observational prospective multicenter study included 203 patients from the "ThyrQoL" study (ClinicalTrial NCT02167529), who underwent total thyroidectomy between October 2014 and August 2015 in 3 French Hospitals (Nantes, La Roche-sur-Yon, and Limoges)...

Hypopharyngeal cysts are very uncommon pathology. They are presented in adult people over 60 years. Although oncocytic cysts are benign tumors, an incomplete resection causes recurrence. The symptoms are not specific, but the more frequent are dyspnea and foreign body sensation upon swallowing. Diagnosis usually is under general anesthesia during intubation. A flexible fiberoptic laryngoscopy could be insufficient; the trumpet maneuver during this examination can reveled occult cysts. To perform a total resection, the surgeon must have a complete exposition of the operative field...

INTRODUCTION: The vagus nerve has sensory and motor function in the larynx, as well as parasympathetic function in the thorax and abdomen. Stimulation of the superior laryngeal nerve can cause reflexive bradycardia. CASE: We describe a case of a 45-year-old man with pre-syncopal symptoms while exercising, and bradycardia found during cardiology workup. Radiography and flexible laryngoscopy showed evidence of a right-sided, vascular laryngeal mass. Exercise testing before and after superior laryngeal nerve block showed reversal of the symptoms with the block...

BACKGROUND: The ability to precisely predict which intubations will be difficult during administration of anesthesia is an importantpart of preoperative preparation. This study's goal is to accurately identify patients who will be difficult to intubate using the number of tracheal rings observed preoperatively by fiberoptic laryngoscopy. METHODS: We enrolled 994 adult patients in our study who required general anesthesia and orotracheal intubation for their elective surgeries...

INTRODUCTION: Awake nasal or oral flexible fiberoptic intubation is the airway management technique of choice in known or anticipated difficult airway, unstable cervical fracture, limited mouth opening (as in temporomandibular joint disease), mandibular-maxillary fixation and severe facial burns. Both optimal intubating condition and patient comfort are important for fiberoptic intubation. Optimal intubating conditions provided by an ideal sedation regimen would ensure haemodynamic stability, patient comfort, attenuation of airway reflexes and amnesia...

Difficulty in tracheal intubation in paediatric intensive care patients is associated with increased morbidity and mortality. Delays to intubation and interruption to oxygenation and ventilation are poorly tolerated. We developed a safe and atraumatic tracheal intubation technique. A floppy-tipped guidewire and airway exchange catheter were placed to a pre-determined length under bronchoscopic guidance while oxygenation and ventilation was maintained via a supraglottic airway device (SAD). We performed a retrospective review of this technique on patients who were either known to have or who had an unexpected difficultly in intubation...
