Table 1 Classification of paragangliomas
Glasscock-Jackson classification | Fisch classification | Shamblin classification | ||||
TPG | JPG | JPG | Carotid PG | |||
Type 1 | Small mass limited to the promontory | Involves jugular bulb, middle ear, mastoid process | Type A | Limited to middle ear cleft | Type 1 | Tumors are localized with minimal vascular attachments. These are easily amenable to complete resection with very little morbidity |
Type 2 | Tumor completely filling the middle ear | Extends under canal, with or without intracranial extension | Type B | Limited to the tympanomastoid area; cortical bone over jugular bulb intact | Type 2 | Tumors partially surround the carotids. These are careful surgical excisions |
Type 3 | Tumor filling middle ear and mastoid | Extends into petrous apex with or without intracranial extension | Type C (C1-C2-C3) | Involving the infralabyrinthine compartment and petrous apex of the temporal bone | Type 3 | Tumors encase the carotids. Surgical resection is difficult and may require major vessel reconstruction |
Type 4 | Further extension through the EAC or anteriorly to the carotid artery | Extends beyond petrous apex into clivus or infratemporal fossa, with or without intracranial extension | Type D (D1-D2-D3) | Glomus jugular tumors with intracranial extensions |
