Case ReportsFourth branchial pouch sinus with recurrent deep cervical abscesses successfully treated with trichloroacetic acid cauterization.
A previously healthy 13-year-old girl presented with a left-sided deep cervical abscess. A CT scan demonstrated an abscess in the lower neck, anterior to the common carotid artery. Treatment with i.v. antibiotics and incision drainage resolved the condition. ⋯ Three cauterizations were needed to close the pyriform sinus opening. To date (Month 14) there has been no recurrence of the cervical abscesses. TCA chemocauterization seems to be a safe first-line treatment for patients with a pyriform sinus fistula.

Cochlear blood flow modifications induced by anaesthetic drugs in middle ear surgery: comparison between sevoflurane and propofol.
Because it is necessary to maintain controlled hypotension during middle ear surgery in order to avoid bleeding and as it is known that cochlear blood flow (CBF) is related to blood pressure (BP), it is useful to evaluate CBF modifications induced by anaesthetics in order to prevent cochlear damage. The aim of this paper is to evaluate, using laser Doppler flowmetry, which anaesthetic drug, out of sevoflurane and propofol, has the smallest effect on CBF. ⋯ The results obtained show that sevoflurane has a hypotensive effect without modifying CBF, while propofol, although having a similar effect on BP to sevoflurane, has less of a protective effect on inner ear microcirculation.
