Randomized Controlled Trial Clinical TrialEfficacy of external fixation following nasal manipulation under local anaesthesia.
Nasal fractures are one of the commonest reasons for patients being referred to ENT departments, but few studies have been published about the management of this condition. In particular, the efficacy of external splintage following manipulation has not been assessed. This was a prospective randomized study, which examined the results of manipulation under local anaesthetic and the benefit to be gained from external fixation with Plaster of Paris (POP) following this procedure. ⋯ The mean deviation of the nasal bridge at presentation was 4.12 mm. Manipulation under local anaesthetic significantly improved the degree of deviation (mean 2.47 mm, P = 0.0011, 90% CI, 1-2 mm). Randomization of the patients, following manipulation, into POP/none-POP groups showed that external splintage of the nose appeared to be of little practical benefit.

The influence of age and gender on the pharyngeal pressure wave during swallowing was investigated in 73 healthy volunteers using a four-sensor manometry probe. The distal sensor was placed within the upper oesophageal sphincter (UOS) and three proximal sensors were located in the pharynx 2, 4 and 6 cm above the UOS. Twenty-nine variables describing the amplitude and timing of the swallow waveforms for a 5 ml water bolus were recorded from the pharynx and the UOS. Analysis of the results indicated that aging was associated with slowing of the swallow response in the pharynx, impaired opening of the UOS and a marked reduction in resting UOS tone.
