To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours.

Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled.

Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

A bifid inferior turbinate is an extremely rare anatomical variation and has been reported in only two cases to date. Including the present report, the uncinate processes were missing in all three patients reported. It is suggested that, in the reported patient, bifid inferior turbinate coexisted with a developmental anomaly of the uncinate process, and that the bifid inferior turbinate represented two separate turbinates originating from the same site.

We present the first reported case of bilateral bifid inferior turbinates, with a secondary middle turbinate, in a patient complaining of nasal obstruction.

We suggest that the superior part of the bifid inferior turbinate may have been formed by severe medial displacement and inferior rotation of the uncinate process, and that the bifid inferior turbinate is an anatomical abnormality of the uncinate process.

The aim of this study was to determine how aware ENT practitioners are that Naseptin® (Alliance), widely used in ENT practice, contains peanut oil and to what extent this is conveyed to patients.

A questionnaire was sent out to all ENT practitioners registered with the British Association of Otolaryngologists.

Analysis of the data confirmed that Naseptin cream is widely used in ENT practice and showed that although most practitioners are aware that Naseptin cream contains refined peanut oil (arachis oil) (74.3 per cent of consultants and 93.6 per cent of registrars) not all ask their patients whether they are allergic to peanuts (62.6 per cent of consultants and 87.3 per cent of registrars).

The results suggest that more should be done to raise awareness amongst practitioners that Naseptin cream contains peanut oil and should be avoided in patients with a peanut allergy, as recommended by national guidelines. The use of Naseptin cream when contraindicated may have medicolegal implications.
