“…This result is ascribable to the discovery by Kuroyanagi et al [15] that a medial ramus type significantly affects operation time and blood loss. In the study of Kuroyanagi et al [15], 59% of patients had a moderately straight medial ramus whereas the rest (41%) had a concave medial ramus. The operation time for patients with a moderately straight medial ramus was significantly shorter, and a mean blood loss of 53 mL was discovered in patients with a moderately straight medial ramus.…”

“…Nonetheless, Koba et al [35] reported a mean blood loss of only 41.6 mL in piezoelectric surgery, which differs from the findings of Shirota et al [16] and is significantly lower than the blood loss in traditional SSRO. Kuroyanagi et al [15] reported a mean blood loss of only 73.3 mL in traditional SSRO, significantly lower than those measured by Shirota et al [16] (189 mL), Handa et al [18] (propofol-remifentanil: 118.4 mL; propofol-fentanyl: 171.7 mL, and Salma et al (176.67 mL). This result is ascribable to the discovery by Kuroyanagi et al [15] that a medial ramus type significantly affects operation time and blood loss.…”

“…IVRO had a total 43 articles using the search terms "intraoral vertical ramus osteotomy" and "blood loss" in the PubMed (n = 13), Web of Science (n = 23), and Cochrane Library (n = 7) databases. Of these, 139 articles were retained by further narrowing to 6 articles [15][16][17][18][19][20] (SSRO: 4; IVRO: 2) whose domain is in a singlemandibular operation (Table 1).…”

“…Statistically, patients with a moderately straight medial ramus led to significantly less blood loss than those with a concave medial ramus. In terms of the potential correlation between blood loss and operation time, Kuroyanagi et al [ 15 ], Shirota et al [ 16 ], Handa et al [ 18 ], Salma et al [ 19 ], and Ueki et al [ 12 ] all found a significantly positive correlation between them, whereas Böttger et al [ 36 ] deemed the correlation between them to be weak.…”

Purpose. The purpose of the present study was to review the literature regarding the blood loss and postoperative pain in the isolated sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO). Materials and Methods. Investigating the intraoperative blood loss and postoperative pain, articles were selected from 1970 to 2021 in the English published databases (PubMed, Web of Science, and Cochrane Library). Article retrieval and selection were performed by two authors, and they independently evaluated them based on the eligibility criteria. The articles meeting the search criteria had especially at least 30 patients. Results. In the review of intraoperative blood loss, a total of 139 articles were retrieved and restricted to 6 articles (SSRO: 4; IVRO: 2). In the review of postoperative pain, a total of 174 articles were retrieved and restricted to 4 articles (SSRO: 3; IVRO: 1). The mean blood loss of SSRO and IVRO was ranged from 55 to 167 mL and 82 to 104 mL, respectively. The mean visual analog scale (VAS) scores of the first postoperative day were 2 to 5.3 in SSRO and 2.93 to 3.13 in IVRO. The mean VAS scores of the second postoperative day were 1 to 3 in SSRO and 1.1 to 1.8 in IVRO. Conclusion. Compared to traditional SSRO, IVRO had a significantly lower amount of blood loss. However, the blood transfusion is not necessary in a single-jaw operation (SSRO or IVRO). Postoperative pain was similar between SSRO and IVRO.
