First branchial cleft sinus or fistulae may be associated with first branchial arch abnormalities. Patients may have unilateral or bilateral facial palsy, hemifacial microsomia or first branchial arch syndromes such as Treacher Collins syndrome. Patients with first arch abnormalities have a higher propensity for concurrent otologic anomalies and hearing screening should be performed. In patients with any branchial abnormality, particularly if bilateral, the potential association with hearing loss, pinna abnormalities and renal malformations, known as branchio-oto-renal syndrome, should be considered with a low threshold for hearing assessment and renal ultrasound.

Yes, both hearing loss (conductive, sensorineural or mixed) and second branchial cleft anomalies are major criteria of branchio-oto-renal syndrome. I would examine for other abnormalities (e.g. preauricular pits etc.), enquire about family history (autosomal dominant with variable penetrance) and ensure the child was referred for a renal USS and to a paediatrician/geneticist for further assessment.

It is also important to highlight the category of hereditary hearing loss, which may be one of the main benefactors in the development of an inner ear targeted gene therapy. Early onset forms of deafness, often presented as hereditary deafness, has been indicated to result from a wide array of genes, with an estimation that over 50% of congenital deafness presentations in newborns are hereditary in nature [33,34]. Classifications of genetic deafness are derived based upon the mutation inheritance mode, with ongoing novel discoveries of genes associated with hearing loss. Molecular genetic tests can be used to identify deafness, both syndromic and non-syndromic in nature. Genetic counselling is a key element in the diagnosis, with modes of inheritance listed as including autosomal recessive and dominant, in addition to X-linked Mendelian and mitochondrial inheritance from a maternal lineage. Syndromic hearing loss which is autosomal recessive in nature includes Usher syndrome and Pendred syndrome, whilst those which are autosomal dominant include Branchio-oto-renal syndrome and Waardenburg syndrome [35–37].

Kidney agenesis, part of HWWS syndrome, is a component of some syndromes such as branchio-oto-renal syndrome (BORS), it can be accompanied with inner and middle ear anomalies (Genetic and Rare Diseases Information Center 2011). To our knowledge, no inner ear anomaly with HWWS syndrome has been reported in the literature. In this report, a case of HWWS with an uncommon appearance in a 13-year-old girl with an inner ear anomaly is presented.

Branchiootorenal syndrome (BOR) is an autosomal dominant disorder manifesting with branchial, otological and renal anomalies presenting as branchial fistulae or cysts, cup-shaped pinnae, preauricular pits, middle and/or inner ear malformations and renal dysplasia. Hearing loss – conductive, sensorineural or mixed, is documented as the most common consequence of BOR (Fraser, Sproule and Halal, 1980).
