Randomized Controlled Trial
Efficacy of medical therapy in the prevention of residual dizziness after successful repositioning maneuvers for Benign Paroxysmal Positional Vertigo (BPPV).
The aim of this study was to investigate the efficacy of trimetazidine, betahistine, and ginkgo biloba extract in the treatment of residual dizziness after successful repositioning maneuvers for benign paroxysmal positional vertigo. ⋯ Our study results suggest that betahistine, trimetazidine, and gingko biloba extract do not alleviate residual dizziness after successful repositioning maneuvers.

Randomized Controlled Trial
Oral steroids and intraoperative bleeding during endoscopic sinus surgery.
Our main objective was to investigate the effect of preoperative oral steroids on intraoperative bleeding and quality of the surgical field during endoscopic sinus surgery (ESS). Our second objective was to determine whether the osteitis score could be used to predict the volume of intraoperative bleeding. ⋯ Our findings suggest that using oral corticosteroids, which have rare but serious side effects, is not necessary in the preoperative period. Furthermore, we found that the radiological osteitis score was not a suitable marker for predicting intraoperative bleeding volumes.

Randomized Controlled Trial
Middle ear pressure changes with sevoflurane and propofol-remifentanil.
The present study aimed to compare the effects of sevoflurane (a commonly used inhalation anesthetic) and intravenous propofol on middle ear pressure (MEP) and determine the more appropriate option for middle ear operations. Fifty-seven American Society of Anesthesiologists risk class I-II patients aged 18-65 years who were not scheduled for ear or tympanic membrane operations were included in the study. The patients were randomly divided into two groups using the sealed envelope method. ⋯ At 10, 15, and 30 min post-induction, MEP values were significantly higher in Group S than in Group P (P < 0.05). Sevoflurane increased MEP values significantly compared with propofol anesthesia. We conclude that propofol can be used more reliably than sevoflurane in middle ear operations.

Randomized Controlled Trial
Efficacy of preincisional levobupivacaine for adult tonsillectomy patients.
We compared the effects of preincisional peritonsillar infiltration of 5 ml levobupivacaine hydrochloride (50 mg/10 ml) on bleeding during surgery and pain after tonsillectomy in patients aged 16 years or older. ⋯ Preincisional levobupivacaine infiltration seems to be a safe and easily applied medication for postoperative pain control, and decreased the volume of intraoperative blood loss in adult patients after tonsillectomy.

Randomized Controlled Trial
Time-dependent middle ear pressure changes under general anaesthesia in children: N2O-O2 mixture versus air-oxygen mixture.
The aim of this study was to investigate the effects of N2O-O2 mixture (Inspired O2 30%) on middle ear pressure (MEP) in children compared with the effects of an air-oxygen mixture (Inspired O2 50%). ⋯ In brief anaesthesia, nitrogen was not removed from the middle ear quickly in Group 1: middle ear pressure values were higher. The nitrous oxide remained in the middle ear longer and so the possibility of ear toxicity may increase. In Group 2, 50% O2 was rapidly absorbed and removed from the middle ear and so middle ear pressure was not as high. It may be concluded that air-oxygen mixture (Inspired O2 50%) anaesthesia should be recommended as being more reliable in tympanoplasties and other middle ear interventions than a N2O-O2 mixture (Inspired O2 30%).
