Overview
Acoustic neuroma may be classified into three subtypes based on tumor size and into six subtypes based on tumor location.
Staging
Acoustic neuroma may be classified into three subtypes based on tumor size and into six subtypes based on tumor location.
- WIGAND has defined a trinomial classification:
SAMII defines six tumour classes:
| Tinnitus grading system for acoustic neuromas | |
|---|---|
| Grade | Description |
|
I |
No tinnitus |
|
II |
Intermittent or mild tinnitus, can only be heard when the ambient noise is low |
|
III |
Persistent or moderate tinnitus, can be heard every day |
|
IV |
Persistent and severe tinnitus, interfere with work and sleep |
| Dizziness grading system for acoustic neuromas | |
|---|---|
| Grade | Description |
|
I |
No dizziness or imbalance |
|
II |
Occasional and mild dizziness or imbalance |
|
III |
Persistent or moderate vertigo or imbalance |
|
IV |
Persistent and severe dizziness or imbalance, disturbing daily life |
