BACKGROUND: Disorders of the ear, nose and throat may be the most commonly occurring pre-existing health condition in international travellers. Despite their high incidence, there is limited guidance for travellers and their clinicians on their prevention and management. This narrative review addresses this deficit by compiling and discussing available evidence on this neglected subject. METHODS: A comprehensive review of the literature was undertaken using Medine and Scopus databases and multiple combinations of relevant MeSH search terms. Further references were obtained from focused searches on specific issues and manual review of the reference lists of articles obtained from the primary search. RESULTS: Nasal congestion or discharge are among the most common complaints amongst travellers and various causes are reviewed. Changes in elevation result in a pressure differential between the atmospheric pressure and the middle ear and paranasal sinuses. The effects of air travel, recreational high-altitude exposure and diving are considered. Various causes of epistaxis in travellers such as cold air exposure and recreational cocaine use are discussed. The aetiology of a discharging ear in travellers includes otitis externa. The most frequently described travel-specific aetiology of dizziness is motion sickness while mal de debarquement is a specific subtype which affects travellers and is most commonly associated with sea travel. Surgical tourism for treatment of ear, nose and throat pathology is well established and various precautions are presented for post-operative travel. Obstructive sleep apnoea is discussed from the perspective of international travel. The challenges facing travellers with hearing impairment are explored. CONCLUSIONS: This review critically discusses the prevention, diagnosis, and management of acute and chronic ENT conditions in the travelling population. Several areas of inquiry are highlighted that require further investigation. Close communication between ENT specialists and travel medicine practitioners is recommended in the preparation of selected patients for international travel.
