The British Association of Head and Neck Oncologists (BAHNO) is ’a multidisciplinary society for healthcare professionals involved in the study and treatment of head and neck cancer’. Surgical members of this organization are from three specialities (otolaryngology, maxillo-facial and plastic surgery). Although the overall impression is that the management of UK head and neck cancer patients is consensus based, there are appreciable differences in each surgical speciality’s practice. Anecdotally, this can lead to variation in the management of very similar patients. To identify some of these variations BAHNO surgeons were surveyed regarding their current head and neck cancer practices from the perspectives of surgical activity and post-operative care. Some unexpected differences were identified, particularly in relation to post-operative care with plastic and maxillo-facial surgeons demonstrating different patterns of high dependency unit (HDU) and intensive care unit (ICU) use for the same patients. The implications for future consensus in the light of these variations are discussed.
