A prospective study was performed to compare Telfa,® paraffin gauze, Merocel® and BIPP used postoperatively following septal or turbinate surgery. Packs were assessed in terms of patient comfort, control of bleeding and ease of removal. There was little to choose between the packs while they were in situ and there was no significant difference in ease of removal. On removal the Telfa® and paraffin gauze were associated with less discomfort and less bleeding than BIPP or Merocel® (p<0.05).
Transmission of intracranial pressure (ICP) to the perilymph of the cochlea may occur via the cochlear aqueduct and possibly other routes. Indirect measurement of perilymphatic pressure may be investigated by observing tympanic membrane (TM) displacement during stapedial reflex contraction. In a previous study we investigated the effects of changes in ICP on perilymphatic fluid pressure in three patients who underwent ventriculo/lumbar-peritoneal shunt operations. The TM displacement technique proved extremely sensitive and revealed marked changes in cochlear fluid pressure brought about by changes in ICP (Marchbanks et al., 1987). The study has been extended to 58 patients with hydrocephalus, intracranial tumours and other neurological conditions associated with abnormal ICP. Significant differences in the TM displacement were found between patients with raised and normal ICP. We have shown that changes in ICP can affect the hydrostatic pressure of the cochlea and influence the peripheral auditory system. The finding that ICP can be correlated with TM displacement strengthens the association between an abnormal TM displacement and abnormal cochlear hydrostatic status, irrespective of cochlear aqueduct patency. We suggest that the TM displacement technique provides a useful non-invasive method for the assessment of perilymphatic fluid pressure.
Necrotizing fasciitis is a rare but well recognized clinical entity which most often occurs on the trunk, perineum or legs following surgery or trauma. The condition is much less common in the head and neck and it is particularly uncommon in the midface/periorbital region. In almost all the cases occurring in the neck the condition follows obvious dental or oropharyngeal sepsis and in all the cases of the scalp there is a history of previous surgery or trauma. However, necrotizing fasciitis of the midface/periorbital region may lack any obvious traumatic aetiology or may follow relatively minor trauma. The diagnosis in these cases may not be suspected and treatment may be delayed with fatal consequences. Treatment by wide excision of all affected skin can lead to disastrous cosmetic consequences in facial disease and it is suggested that disease control can be achieved by raising wide based skin flaps with excision of the underlying necrotic tissue. The flaps are then returned onto normal muscle with much improved cosmetic results. This paper discusses the diagnosis and treatment of patients with necrotizing fasciitis of the face which has arisen without significant trauma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
