More than 400 genetic syndromes that embody listening to loss have been described Toriello et al 2004 Although syndromic hearing impairment accounts for up to 30% of prelingual deafness, its relative contribution to all deafness is far smaller, commensurate with the occurrence and prognosis of postlingual listening to loss.

Genetic syndromes – These include Usher syndrome, Treacher Collins syndrome, Waardenburg syndrome, Down syndrome, Crouzon syndrome and Alport syndrome. The defect is on chromosome 10p (Gene Map Locus: 10p15, 10p15.1-p14), with haploinsufficiency or mutation of the GATA3 gene being the underlying cause. Inheritance might be autosomal dominant. Management consists of treating the medical abnormalities on the time of presentation. Prognosis depends Digital Health upon the severity of the renal disease. Alloisio N, Morle L, Bozon M et al.

Treacher Collins syndrome is characterised by coloboma of the lower eyelid (the upper eyelid is concerned in Goldenhar syndrome), micrognathia, microtia, hypoplasia of the zygomatic arches, macrostomia, and inferior displacement of the lateral canthi with respect to the medial canthi. Management – if hearing doesn’t recover inside a few days of sudden noise exposure, refer for audiometric testing. Patients complaining of occupational NIHL want referral, as there may be authorized implications.

I read this with a lot interest, as I am now 50, and have really poor listening to, triggered by way of childhood ailments. I answered yes to virtually each query asked, and I wear a BTE listening to assist as a result of my ear canals are too narrow for ITE aids. I still have problems with telephones and puzzled what I might do to beat this. Thank you for a very informative article. Wazem JJ, Spitzer JB, Ghossaini SN, et al.
