Abstract:
The most significant objection to the proposal of lateral transtemporal cranial base surgery for the treatment of jugular foramen tumors is the perceived lasting morbidity attendant to aggregate cranial nerve loss. As techniques become more standardized and earlier diagnosis generates smaller tumors for treatment, outcome has become more predictable. Surgery has become the recognized management preference for these cranial base lesions. The purpose of this article is to assess the role of surgery in the treatment of jugular foramen lesions, as well as to review some of the technical highlights of conservation surgery, its clinical prerequisites, and reasonable expectations. We review 100 lateral skull base surgical cases of lesions involving the jugular foramen. The majority of these lesions--77 of 100--were paragangliomas. For these glomus tumors, cranial nerve preservation correlated well to tumor size and location. The diversity of the remaining 23 cases prevented any substantive conclusions.
Insights
Lateral transtemporal cranial base surgery offers predictable outcomes for jugular foramen tumors, with cranial nerve preservation correlating to tumor size and location in paragangliomas.
Area of Science:
- Neurosurgery
- Otolaryngology
- Skull Base Surgery
Background:
- Jugular foramen tumors pose surgical challenges due to potential cranial nerve morbidity.
- Advancements in surgical techniques and earlier diagnosis improve outcomes for these lesions.
- Surgery is increasingly the preferred management for cranial base lesions involving the jugular foramen.
Purpose of the Study:
- To evaluate the efficacy of lateral transtemporal cranial base surgery for jugular foramen lesions.
- To review surgical techniques, clinical prerequisites, and expected outcomes.
- To assess the correlation between tumor characteristics and cranial nerve preservation.
Main Methods:
- Retrospective review of 100 lateral skull base surgical cases involving the jugular foramen.
- Analysis of lesion types, focusing on paragangliomas (glomus tumors).
- Correlation of tumor size and location with cranial nerve preservation outcomes.
Main Results:
- Paragangliomas constituted the majority (77%) of the lesions treated.
- Cranial nerve preservation was significantly associated with smaller tumor size and specific locations.
- Outcomes for the remaining 23 diverse cases were not conclusive for analysis.
Conclusions:
- Lateral transtemporal cranial base surgery is a viable and effective treatment for jugular foramen lesions.
- Tumor size and location are critical factors influencing successful cranial nerve preservation.
- Further research is needed for diverse jugular foramen lesion management.
