The authors presented a case of operative injury of the internal carotid artery due to sinus surgery on a 13 years old malc, which followed by frequent postoperative hemorrhage.
After repeated nasal packs done in attempts of controlling the hemorrhage had failed ligature of the common carotid artery was made and only this found successful.
Fourteen days later however, a spontaneous rupture of the artery occured with mass hemorrhage at the ligated site and necessitated the second ligature of the artery.
The authors also discussed the anatomy of the posterior most of the paranasal sinuses in relation to the location of the internal carotid artery.
