AVP and sinusitis: Table 3 shows an overview of immunohistochemistry results, with pathological classifying diagnoses in Supplementary Table S3b (26). The primary surgical technical goal (ie, total resection or debulking) was achieved in 90 patients (female: n = 66 [91.7%], male: n = 24 [85.7%]). Transient complications or adverse events occurred in 11 patients, consisting mostly of syndrome of inappropriate antidiuretic hormone secretion necessitating readmission (n = 3), or sinusitis necessitating antibiotics (n = 3). An overview of all transient complications is shown in Supplementary Table S4 (26).
