[Hereditary hearing loss: Part 2: Syndromic forms of hearing loss]

Area of Science:

• Genetics
• Otolaryngology
• Medical Diagnostics

Context:

• Syndromic hearing loss constitutes approximately 30% of all inherited hearing loss cases.
• It is distinguished from nonsyndromic hearing loss by concurrent symptoms affecting other organ systems.
• While genetic causes for many syndromic hearing loss types are known, the origins of associated symptoms are often unclear.

Purpose:

• To differentiate syndromic hearing loss from nonsyndromic forms.
• To highlight the importance of identifying responsible genes in syndromic hearing loss.
• To define the role of ENT physicians in diagnosing and managing hearing loss.

Summary:

• Syndromic hearing loss, a significant portion of inherited hearing impairment, involves extra-auditory symptoms.
• Genetic identification is advancing, yet the etiology of associated symptoms requires further investigation.
• ENT specialists play a key role in selecting diagnostic tools and initiating therapeutic interventions for hearing loss.

Impact:

• Improved diagnostic strategies for syndromic hearing loss.
• Enhanced understanding of the genetic and etiological factors contributing to associated symptoms.
• Optimized management and treatment protocols for patients with syndromic hearing loss.
