Aspiration, swallowing dysfunction and chronic lung injury
Also known as Chronic pulmonary aspiration · Oropharyngeal dysphagia · Aspiration lung disease · Silent aspiration · Salivary aspiration and sialorrhoea · Feeding and swallowing disorder
Fellowship guide to aspiration, swallowing dysfunction and chronic lung injury in children: the child who mis-directs feeds, refluxed gastric contents or saliva into the airway and slowly damages the lung; the three aspiration routes and the phases of swallowing; recognising the recurrent wet cough, wet voice, feeding-related choking and the silent aspiration of the neurologically impaired child; confirming it with a clinical feeding assessment, videofluoroscopy or FEES rather than a single test; grading lung impact from occasional wet cough to bronchiectasis; and the multidisciplinary bundle of texture modification, thickened fluids, salivary control with anticholinergics, botulinum toxin and surgery, reflux management, airway clearance and prompt antibiotics, across ANZ, UK and North American practice.

Target exams
Red flags
- Coughing, choking, gagging or colour change with feeds, or a wet gurgly voice after feeding — the bedside signature of unsafe swallowing that should stop oral feeding until it is assessed
- Recurrent or persistent wet cough and repeated pneumonias, especially in the same dependent lung region — think chronic aspiration and look for the route before labelling it asthma
- The neurologically impaired child who never coughs on feeds yet has chronic chest disease — silent aspiration is common and its absence of symptoms is falsely reassuring
- Weight faltering, food refusal, prolonged mealtimes over 30 minutes, or mealtime distress — feeding is failing and nutrition and airway safety are both at risk
- An acute large-volume aspiration event with new hypoxia, respiratory distress or a lobar collapse — this is an emergency needing resuscitation, not a clinic problem

Overview & Definition
Picture a four-year-old with cerebral palsy brought to clinic with his third "chest infection" this year. Mealtimes take forty minutes, he splutters on thin drinks, his voice sounds wet afterwards, and each illness settles in the same right lower zone. That pattern — recurrent wet chest disease anchored to feeding and to one lung region — is chronic aspiration, and naming it turns a string of antibiotic courses into a treatable feeding-and-airway problem. [1] [2]
Aspiration means material passing below the vocal cords into the airway instead of down the oesophagus. A single small event is common and usually harmless, but when a child aspirates repeatedly the lung is injured by the volume, the acidity and the bacterial load of what goes down, and by the failure to clear it. This is why the exam framing is about a chronic process rather than one dramatic choke. [1] [2]
Why this matters at fellowship level is that aspiration is a common, missed and modifiable cause of chronic lung disease in children with disability. The skill being examined is recognising it despite silent presentations, working out the route, and coordinating a team rather than reaching for repeated antibiotics alone. [1] [11]
