Abstract
Background: Pneumocephalus is a common finding after burr-hole drainage of chronic subdural hematoma (CSDH). Its effects have not been specifically studied.Methods: A retrospective analysis was performed in 140 patients with CSDH with single burr-hole drainage. The pre- and postoperative volumes of intracranial hematoma and the postoperative volume of pneumocephalus were calculated and analyzed with their relationships with Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) scores.Results: The preoperative hematoma volume and the patient ages are positively correlated with the 1-day postoperative pneumocephalus volume (p < 0.001, p < 0.01). There is no correlation between postoperative pneumocephalus volume and GCS/GOS scores (p > 0.05) and there is no difference of GCS/GOS scores or CSDH recurrence rate between patients with and without pneumocephalus (p > 0.05). The age and the volume of 1-day postoperative pneumocephalus are positively correlated with the absorbing rate of pneumocephalus (p < 0.01, p < 0.001).Conclusions: The pneumocephalus at a certain range has no effect on the prognosis of patients with CSDH and requires no specific intervention due to its self-absorbing capacity in the normal progress after surgery.HighlightsNo correlation between postoperative pneumocephalus volume and GCS/GOS scores.No difference of GCS/GOS or recurrence between patients with pneumocephalus or not.Pneumocephalus at certain range has no effect on the prognosis of patients.
