Review
Acoustic neuroma is a rare but important cause of sensorineural hearing loss. Patients with asymmetric hearing loss or unilateral tinnitus should be evaluated expeditiously to prevent further neurologic damage. Gadolinium-enhanced magnetic resonance imaging is the best tool for making the diagnosis of acoustic neuroma. Surgical removal using a translabyrinthine approach, is the favored treatment, although radiation therapy and expectant management may be chosen for patients at high surgical risk.

This study developed a technique for magnetic resonance imaging (MRI)-based volume calculation and defined the specific volume-diameter relationship in acoustic neuromas (AN). Computer-assisted measurement calculated the area of tumor in each MRI slice. Volume was determined by multiplying area by slice interval. The technique was validated by imaging known volumes of gadolinium. The precision was greater than 95%. Our volume calculations revealed a specific volume-diameter relationship in ANs. The following conclusions can be drawn: 1. our technique can accurately determine AN tumor volume; 2. the AN volume-diameter relationship is a specific function and cannot be predicted by assumptions of tumor shape; 3. the volume-diameter relationship should be combined with clinical data to determine the "break point" at which small increments of diameter produce significant clinical sequelae.

A cost-effective approach to the diagnosis and treatment of acoustic neuromas continues to evolve as diagnostic methods improve. In the past 7 months, since gadolinium-enhanced magnetic resonance imaging (MRI) has become available in our practice, our screening and presurgical workup has changed. The purpose of this article is to outline the current philosophy of the senior authors in relation to acoustic neuroma management on the basis of 72 patients diagnosed from July 1988 to February 1989. With more sensitive diagnostic means, older less sensitive studies may be eliminated from the routine workup, thus maintaining cost-effectiveness while preserving the highest standard of patient care. The body of this article will review our current use of the many available diagnostic options and emphasize a cost-effective approach.

INTRODUCTION
Acoustic neuroma (AN) research largely employs a medical framework to understand health outcomes. An alternative is to examine quality of life (QOL) outcomes. This study explored whether mental well-being (i.e., anxiety and depression) were predictive of QOL in those with AN over and above symptomatology.
METHODS
A nationwide online survey was distributed to 24 community organisations. The inclusion criteria were a diagnosis of AN irrespective of the treatment approach. There were 52 respondents. Mental well-being was assessed using the Hospital Anxiety and Depression Scale (HADS), and quality of life was assessed using Penn Acoustic Neuroma QOL scale (PANQOL).
RESULTS
The most frequently reported symptoms reported were poor balance, tinnitus, hearing loss, and headache. Preliminary analyses suggested that headaches, tinnitus and mental well-being were significantly correlated with QOL. Hierarchical regression revealed that these two symptoms and mental well-being accounted for 18.7% and 51.1% of the variance in QOL, respectively. In addition, there was a significant difference in depression scores between management types, with the surgery group having a significantly higher depression score than the radiation group.
CONCLUSION
Symptoms and mood contribute to QOL for those diagnosed with AN. This can be understood through the common-sense model and fear of cancer recurrence. Screening for psychological difficulties should be provided from the point of diagnosis to post-treatment to allow for targeted management plans to mitigate the effects of these on QOL.

Vestibular schwannomas can severely impair the quality of life of patients. Next to impaired hearing function, facial palsy is perceived as particularly disturbing in this context. Varying growth rates of these benign tumors complicate a prediction of functional impairment of cranial nerves. Therefore, a regular update on current therapeutic strategies and alternative treatment options is relevant for both physicians and patients.

The progress of the diagnostic and treatment of the acoustic tumors have begin in the years 1960. From this time, radio imaging, surgical and anasthesic techniques have improved in such a way that the lethality of the surgery is almost equal to 0% and the preservation of the facial mimic have reached a point that was never attained before. It must be emphasized that this surgery requires a surgical staff well trained and an appropriate structure. The preservation of hearing remains and will remain possible in some exceptional cases, as we know how fragile is this function in most of the cases.

Review
A survey of the management of acoustic neuromas in the broadest sense is given. The epidemiology and pathogenesis is described. The clinical development may take any imaginable course, and even though a slowly progressing unilateral hearing impairment, of the sensorineural type, is the main pattern of presentation, it is stressed that any type of symptom could appear in an acoustic neuroma patient. In order to make an early diagnosis a high index of suspicion must be the basic principle, with all patients with unilateral symptoms, not only hearing deficits, being suspected of suffering from acoustic neuromas until proven otherwise. All patients with hearing better than 70-80 dB should be subjected to ABR, and if there is any doubt about the normality of the response, the patient should proceed to MRI. Patients with poor hearing should go directly to MRI. The advantages and disadvantages of the different surgical approaches are described and an electric treatment algorithm is outlined: 1) All tumors measuring 25 mm or more on MRI are operated via the translabyrinthine approach. 2) All patients with PTA poorer than 30 dB, and SDS poorer then 70% are operated via the translabyrinthine approach. 3) Tumors less than 10 mm extrameatally, and PTA better than 30 dB and SDS better then 70% are removed via the middle fossa route. 4) Tumors measuring 10-25 mm and PTA better than 30 dB and SDS better than 70% are removed via the suboccipital route.
