Which type of neurofibromatosis is associated with ear issues due to CN VIII schwannomas?

Neurofibromatosis type 2 (NF2) is specifically associated with the development of bilateral vestibular schwannomas, which impact cranial nerve VIII, leading to auditory and balance issues. Individuals with NF2 often experience hearing loss, tinnitus, and balance difficulties as a result of these tumors affecting the acoustic and vestibular components of the nerve.

Whereas neurofibromatosis type 1 (NF1) is characterized by neurofibromas, café au lait spots, and other skin changes, it does not typically involve schwannomas of cranial nerve VIII. Malignant forms of neurofibromatosis can occur but are not the focus in this context, as they do not specifically relate to the hallmark features of NF2 regarding ear issues. The term "common" does not refer to any specific type of neurofibromatosis but is too vague in this context.
