Hereditary deafness is considered one of the health conditions that affect the sense of hearing due to the transmission of certain genes or genetic mutations from parents to children. It may appear at birth or during the early stages of life. It is one of the most common causes of hearing loss in children, as genetic factors play a major role compared to environmental or disease-related causes. Hereditary deafness occurs because of defects in the genes responsible for the formation of the inner ear or auditory nerves. Hearing loss may be partial or complete, and it can occur alone or as part of other genetic syndromes that affect different organs of the body. The severity of the condition varies from one person to another depending on the type of genetic mutation and the pattern of inheritance. The most common symptoms of hereditary deafness include lack of response to sounds, delayed speech and language development, and difficulty communicating with others. Therefore, early detection is extremely important to reduce its impact on the child’s linguistic, educational, and social development. For this reason, many hospitals conduct newborn hearing screening programs to identify hearing problems at an early stage. Diagnosis of hereditary deafness is carried out through hearing examinations and genetic testing, which help identify the type of genetic disorder. Family medical history also plays an important role in determining the possibility of the condition being passed through generations. Treatment depends on the degree of hearing loss and may include hearing aids, cochlear implants, and auditory and speech rehabilitation sessions to improve communication skills. Raising awareness about hereditary deafness is important in promoting health education regarding the risks of consanguineous marriage in some cases, as well as the importance of genetic counseling before marriage or pregnancy to reduce the possibility of transmitting hereditary diseases to children. In conclusion, hereditary deafness is not an obstacle to success if it is managed properly and detected early. Modern medicine and advanced technologies have helped many affected individuals integrate into society and live normal lives, highlighting the importance of medical, family, and educational support for this group.
