Overview
Symptoms of acoustic neuroma include hearing loss, tinnitus, vertigo, headaches, facial weakness, facial numbness and tingling, dizziness, taste changes, difficulty swallowing and hoarseness and, confusion.[1][2]
Symptoms
Symptoms and signs of Acoustic neuroma considerably dependent on the size of tumor for instance, generalized headacheoccures in less than 20% of patients with small acoustic tumors (less than 2cm), although it can occur in 43 to 75% of patients with tumor over 4cm in diameter.[3] In table 1 and table 2 there are information about the frequency of major symptoms and signs and cranial nerve disturbances respectively. [4]
| Table 1 | |||
|---|---|---|---|
| Major signs and symptoms | Diagnostic accuracy of clinical features in predicting the tumor progress | ||
| Signs and symptoms | Frequency | Sensitivity | Specificity |
| Hypacusis | The most common | High | low |
| Facial paresthesia | Commonly seen | Moderate | Moderate |
| Instability of gait | |||
| Tinnitus | |||
| Hearing loss | Occasionally seen | low | high |
| Headache | |||
| Facial paralysis | |||
| Vertigo | |||
| Absent corneal reflex | |||
| Bucking | Rarely seen | Very low | Very high |
| Visual disorder | |||
| Nausea and vomiting | |||
| Nystagmus | |||
| Movement disorder | |||
| Mastication disorder | |||
| Romberg sign | |||
| Hoarseness | |||
| Abduction disorder | |||
| Ear pain | |||
Cranial nerve
Cranial nerve disturbances was related to the cochlear nerve and trigeminal nerve. The facial nerve disturbances occurs in more sever cases.
| Table 2 | ||
|---|---|---|
| Nerve | Symptop\sign | Frequency |
| V | Trigeminal nerve disturbance | Commonly seen |
| VI | Abduction disorder | rarely seen |
| VII | Facial nerve disturbance | Occasionally seen |
| VIII | Hearing deficits | Mostly seen |
| VIII | Vestibular disturbance | Occasionally seen |
| IX-XII | Caudal cranial nerve deficits | Seldom seen |
