The subgroups who did not receive surgical treatment had worse survival rates than those who did receive treatment. In particular, patients who did not receive any therapy did not live past 1 year. In contrast, the group of patients treated by intranasal resection in combination with radiotherapy and\/or chemotherapy showed a slightly better survival rate. It is important to note that the group of patients treated by craniofacial surgery combined with radiotherapy and\/or chemotherapy had a markedly favorable prognosis, with 1\u2010, 3\u2010, and 5\u2010year overall survival rates of up to 100%, 88%, and 66%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Craniofacial surgery in combination with radiotherapy and\/or chemotherapy was an effective treatment for intracranial invasive ONB.

the prognosis of
