Introduction: First branchial cleft anomalies account for less than 8% of all branchial abnormalities. Their rarity and diverse presentations have frequently led to misdiagnosis and inappropriate treatment. In a trend towards specialisation/subspecialisation, first branchial cleft duplication anomalies, with their varied clinical manifestations, may possibly present to an Otology, Head and Neck Surgery, Paediatric Otolaryngology, Maxillofacial or even a General Paediatric and General Surgery practice. There is a need to highlight the clinical features which can aid in accurate diagnosis.
Clinical picture, treatment and outcome: A case of an adult with Work Type 2 first branchial cleft duplication anomaly presenting as a collaural fistula is described. It first presented as a recurrent upper neck abscess in childhood. The diagnosis had previously been missed although the patient was able to clearly establish a correlation between digging of the ipsilateral ear and precipitation of the abscess. Instead of an epidermal web, a myringeal lesion in the form of a fibrous band-like was present. The lesion was completely excised with no further recurrence.
Conclusion: This case highlights useful diagnostic features both from the history and physical examination. The specialist/subspecialist must be aware of this condition and be mindful of its possible cross specialty/subspecialty symptoms and signs. Together with a good understanding of the regional embryology and anatomy, the lesion can be diagnosed early at initial presentation with the potential for best treatment outcomes.
