In this context, intraoperative ultrasound (IOUS) claims to offer real-time feedback of adequacy of surgical decompression, thus accordingly tailoring the aggressiveness of surgery. The present review aims to highlight benefits, limitations, and areas in need of further investigation. Materials and Methods: A comprehensive literature search of PubMed, Scopus, and Google Scholar was performed for studies published in English in the last 30 years. The following keywords, including MeSH terms, were used to retrieve eligible papers: \u201cChiari Malformation Type I,\u201d \u201cposterior fossa decompression,\u201d and \u201cultrasonography.\u201d Results: A total of 3,189 results were collected. Duplicate records were then removed (n = 1,591). A total of 1,598 papers were screened, and 1,531 records were excluded through title and abstract screening; 65 studies were considered relevant to our research question and were assessed for eligibility. Finally, 23 articles were included in the review. Conclusions: IOUS has been frequently used to evaluate the adequacy of surgical decompression, though this qualitative assessment remains subjective with obvious inter-operator variability. On the other side, a quantitative assessment has been more rarely used through the literature, as this approach is difficult to reproduce. Despite the obvious advantages of IOUS, further investigation is required to standardize this approach.<\/jats:p>","DOI":"10.1159\/000550058","type":"journal-article","created":{"date-parts":[[2025,12,13]],"date-time":"2025-12-13T17:00:31Z","timestamp":1765645231000},"page":"166-175","source":"Crossref","is-referenced-by-count":1,"title":["Tailoring
