An accurate, reliable, inexpensive and safe method for the examination of the upper aero-digestive tract is described. Its efficacy is evaluated retrospectively on 250 patients over an 18-month period.
Twenty-one patients with nasal obstruction due to allergic or vasomotor rhinitis were assessed rhinomanometrically before and after the operation of submucosal diathermy to the inferior turbinates. It was found that the operation significantly improved the nasal airway. Most patients with an objective improvement reported a corresponding reduction in nasal obstruction. There was no tendency for patients with allergic rhinitis to be dissatisfied with the operation.
Flexible fibreoptic rhinolaryngoscopy has been shown to be an accurate, reliable, inexpensive and safe method of examining the upper aero-digestive tract (Lancer and Moir, 1985). The results of 338 consecutive examinations are reported.
The various techniques available for the management of auricular haematoma are reviewed and discussed. A modification of existing methods of treatment employing vacuum drainage is described. This method used in six cases resulted in a satisfactory cosmetic appearance.

The effect of lignocaine on nasal sensation of airflow and nasal resistance was assessed in twenty-five subjects. A randomised crossover trial was conducted with lignocaine as the active drug and saline as the placebo. Both substances were delivered to the nasal mucosa as a nasal spray. Lignocaine caused a sensation of increased nasal patency in twenty-two of the twenty-five subjects studied. Saline had no such effect. The difference between this subjective effect of the two substances was highly significant (p less than 0.001). Neither spray had any significant effect on nasal resistance to airflow assessed objectively by rhinomanometry.
