What is the primary cause of conductive hearing loss?

• A. Obstruction or damage in the outer or middle ear
• B. Fluid accumulation in the inner ear
• C. Neurological defects affecting hearing
• D. Genetic predisposition to hearing loss

Answer: (A)

Conductive hearing loss occurs primarily due to issues that impede the transmission of sound waves through the outer and middle ear. This can be caused by various factors, such as earwax blockage, fluid in the middle ear, perforation of the eardrum, or malformations of the outer or middle ear structures. When these structures are obstructed or damaged, sound cannot be effectively conducted to the inner ear, leading to decreased auditory perception. Fluid accumulation is generally associated with conditions affecting the middle ear, but it does not encompass the full range of possible obstructions within the outer and middle ear that can lead to conductive hearing loss. Neurological defects and genetic predispositions typically pertain to sensorineural hearing loss or problems originating in the cochlea or auditory pathways, making them less relevant to the primary causes of conductive hearing loss. Conductive hearing loss specifically relates to mechanical issues obstructing sound conduction rather than neural processing or genetic factors.
