title: Difficult paediatric intubation when fibreoptic laryngoscopy fails.
abstract: We report an unusual problem with fibreoptic bronchoscopy in an 8-year-old girl with Negar syndrome. She had a history of difficult airway since birth, and had undergone mandibular distraction for severe obstructive sleep apnoea when she was aged 2 years. Nagar syndrome is a Treacher-Collins like syndrome with normal intelligence, conductive bone deafness and problems with articulation. The patients have malar hypoplasia with down slanting palpebral fissures, high nasal bridge, micrognathia, absence of lower eyelashes, low set posteriorly rotated ears, preauricular tags, atresia of external ear canal, cleft palate, hypoplasia of thumb, with or without radius, and limited elbow extension. Protracted attempts with a fibreoptic bronchoscope failed to visualize the glottis, and this was only possible when the tube was guided to the larynx by blind nasal intubation. Apparently, the healing of the wounds for the mandibular distraction in the mandibular space on the inside of the rami of the mandible had caused differential fibrosis on either side of the hyoid, leading to a triplane distortion of the larynx with a left shift, clockwise rotation to a 2-8 o'clock direction and a slight tilt towards the left pharyngeal wall. The large epiglottis overlying this had precluded a view of the larynx. Finally, the older technique of breathguided intubation facilitated fibreoptic bronchoscopy to achieve tracheal intubation.
