Acoustic Neuroma: A benign tumor growing on the cranial nerve running from the brain to the inner ear, affecting balance and hearing. This condition can cause tinnitus, hearing loss, and facial numbness due to its location and impact on surrounding nerves.

Meniere's Disease: A disorder of the inner ear that causes episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. While it primarily affects balance, it can also lead to hearing loss and tinnitus.
Labyrinthitis: An inner ear disorder characterized by inflammation of the part of the inner ear responsible for balance and hearing, leading to symptoms like tinnitus, hearing loss, and sometimes facial numbness if the inflammation affects nearby nerves.
Ototoxicity: Certain medications or chemicals can damage the inner ear, leading to hearing loss and tinnitus. If the damage extends to the facial nerve, it could result in facial numbness.

Multiple Sclerosis (MS): An autoimmune disease that affects the brain and spinal cord, leading to a wide range of neurological symptoms. While less common, MS could present with a combination of these symptoms, especially if there are lesions affecting the brainstem or cranial nerves.
Stroke or Transient Ischemic Attack (TIA): Although the question specifies "no weakness," it's crucial to consider stroke or TIA, especially if the facial numbness is unilateral and sudden in onset. Some strokes, particularly those in the brainstem, can present with atypical symptoms.
Cerebellopontine Angle (CPA) Tumors (other than Acoustic Neuroma): Other tumors in this region, such as meningiomas or epidermoids, can also cause these symptoms by compressing nearby nerves.

Ramsay Hunt Syndrome Type 2: A condition caused by the varicella-zoster virus (the same virus that causes chickenpox and shingles) affecting the geniculate ganglion of the facial nerve, leading to facial paralysis, ear pain, and sometimes hearing loss and tinnitus.
Sarcoidosis: A disease in which abnormal immune cells, called granulomas, form in various parts of the body, including the nervous system. It can cause a wide range of neurological symptoms, including those mentioned, though this would be a less common presentation.
Neurosyphilis: A complication of untreated syphilis infection that can affect the nervous system, potentially causing a variety of symptoms including hearing loss, tinnitus, and facial numbness, especially in the tertiary stage.
