What is Sensorineural Hearing Loss?
Sensorineural hearing loss (SNHL) is a type of hearing impairment resulting from damage to the inner ear or the auditory nerve that transmits sound signals to the brain. This condition can significantly impact an individual's quality of life, leading to difficulties in communication, social isolation, and emotional distress.
Chemotherapy: Drugs like cisplatin and carboplatin are ototoxic, meaning they can damage the hair cells in the cochlea, leading to hearing loss.
Radiation Therapy: Radiation to the head and neck can damage the inner ear structures or the auditory nerve.
Surgery: Surgical procedures for tumors near the auditory system, such as those for acoustic neuroma, can inadvertently damage auditory structures.
Difficulty hearing conversations, especially in noisy environments
Ringing in the ears (
tinnitus)
Vertigo or dizziness
Feeling of fullness or pressure in the ears
Audiometry: To assess the degree and type of hearing loss.
Imaging studies: MRI or CT scans to identify structural causes, such as tumors.
Blood tests: To rule out other causes or complications related to cancer treatment.
Monitoring: Regular hearing assessments before, during, and after treatment.
Protective agents: Research is ongoing into agents that may protect against ototoxicity, such as
amifostine.
Dosage adjustment: Modifying chemotherapy doses or schedules to minimize ototoxicity.
Hearing aids: To amplify sound and improve hearing function.
Cochlear implants: For severe or profound hearing loss where hearing aids are ineffective.
Rehabilitation: Speech therapy and auditory training to improve communication skills.
Conclusion
Sensorineural hearing loss is a significant concern for cancer patients undergoing treatment. Understanding its causes, symptoms, and management options is crucial for healthcare providers to improve patient outcomes and quality of life. Regular monitoring and early intervention are key to mitigating the impact of SNHL in this vulnerable population.
