To evaluate the histopathologic tissue changes in embolized head and neck paragangliomas relative to the elapsed time between embolization and surgical resection.
Histologically examined 48 surgical specimens of head and neck paragangliomas (glomus tumors) alongside clinical case history reviews.
Tracked tissue responses, inflammatory reactions, vessel occlusion rates, and revascularization across multiple post-procedure time intervals.
Thrombus formation and foreign body giant cells occurred during the first 7 days, followed by active phagocytosis, embolic fragmentation, and partial revascularization thereafter.
Approximately one-third of tumor vessels were embolized, with complete obliteration achieved in 40% of embolized vessels after more than 2 months.
Tissue alterations followed four distinct histologic stages, identifying the first 8 days postembolization as the optimal surgical window, though later surgery was not compromised by revascularization.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Histopathologic study reveals optimal surgical timing within eight days after embolization in head and neck paragangliomas, indicating delayed resection remains viable despite revascularization.
