The anatomy of the arterial supply of the inferior turbinate was studied by dissection and serial histological sections. The arrangement was found to be constant, with a single main descending branch of the sphenopalatine artery entering its substance from above, 1–1.5 cm from its posterior border. This artery branches as it passes forwards within the turbinate, remaining close to the bone. As these pass anteriorly they give rise to arterial arcades which remain close to or within the bone, with the main artery increasing in diameter. The implications of these findings are discussed in a surgical context.

Textbook descriptions and illustrations of the opening of the sphenopalatine foramen (SPF) into the nasal cavity place it above and behind the posterior end of the middle turbinate (i.e., within the superior meatus). Although true for some skulls, this is not the situation for the majority and may be of importance, because the major blood supply to the nasal cavity enters via this route. Having studied 238 lateral nasal walls, the authors propose a classification of the osteology of the sphenopalatine foramen. In class I (35%) the opening of the SPF is purely into the superior meatus with a notch or foramen in the middle turbinate/ethmoidal crest of the palatine bone. In class II (56%) the SPF spans the ethmoidal crest (i.e., opens into both the superior and middle meati). In class III (9%) there are two separate openings into the superior and middle meati. These findings may explain the route of the artery to the inferior turbinate and indicate the need for care in dealing with the posterior end of the middle turbinate. They may also suggest a potential site for dealing with "difficult" epistaxis via an intranasal route.

One hundred and seven consecutive patients with acute and chronic epistaxis were examined to identify the site and nature of the source. Aetiological factors in the history, nasal anatomy or pathology were noted, along with the blood pressure and laboratory results.In most presentations an anterior bleeding point was isolated. Cautery usually sufficed in both anterior and posterior sources. No source was hidden behind a septal spur or deflection. Hypertension was associated with bleeding from the middle meatus, but not with the severity of bleeding. Patients on antihypertensive medication were more likely to be admitted.Point sources of bleeding were from prominent vessels or haemorrhagic nodules; the latter are not well recognized and are easily overlooked.Routine blood tests did not reveal unsuspected abnormalities or change management; neither did sinus X-rays.Initial examination of the nose in the acute phase by experienced personnel is suggested, to reduce admissions and avoid nasal packing.

Tinnitus, a widespread, often intractable condition, affects millions of people; there is considerable debate about its causes. Tinnitus is distressing and may be severe enough to affect lifestyle and quality of life. Affected patients need considerable support and advice on healthcare options, encouragement to try different treatments and recognition that help and hope are available. Though patients may have to learn to live with tinnitus, the most important thing is that they recognise that help is available.
