Background And Aims: Infratentorial neurosurgical procedures are considered high risk for the development of postoperative pulmonary complications (POPCs), prolonging hospital stay of patients with substantial morbidity and mortality.
Material And Methods: Patients between the ages of 18 and 65 years, who underwent elective surgery for posterior fossa tumors over a period of two years, were reviewed. Data including American Society of Anesthesiologists physical status; comorbidities like hypertension, diabetes mellitus and hypothyroidism, history of smoking, obstructive sleep apnea, respiratory symptoms, lower cranial nerve (LCN) palsy; intraoperative complications such as hemodynamic alterations suggestive of brain stem or cranial nerve handling, tight brain as informed by the operating neurosurgeon, blood loss, and transfusion; and postoperative duration of mechanical ventilation, tracheostomy, POPCs, length of ICU and hospital stay, general condition of the patient at discharge, and cause of in-hospital mortality were collected.
