: This study was designed as a clinical service review to assess current practice, make quality improvements and improve patient outcomes. Since it was undertaken using retrospective de-identified data collected during the course of routine care by the direct care team as part of usual practice, no informed consent was requested from the patients. This was acknowledged by the local Research and Innovation department at Leeds Teaching Hospitals NHS Trust who reviewed the study methods, confirmed waiver of consent and concluded that the study did not require Health Research Authority (HRA) approval and therefore no NHS Research Ethics Committee (REC) review. Research data for this study was obtained from the neurosurgical database created and maintained by the local pituitary surgeons at LTHT (neurosurgeons NP and AT and ENT surgeons PN and TW) as part of routine postoperative practice. No administrative permissions were required to access this anonymized data provided by co-authors NP, AT, PN and TW who shared ownership rights. All methods were carried out in accordance with relevant guidelines and regulations for medical research involving human subjects of the Declaration of Helsinki.
