Case ReportsAccidental full thickness burn of the ear lobe following division of the great auricular nerve at parotidectomy.
Division of the great auricular nerve is commonly performed during superficial parotidectomy and leads to anaesthesia of the ear lobe. In the case presented here, this gave rise to an accidental self-inflicted thermal burn of the ear lobe. This might have been avoided had the posterior branch of the nerve been preserved.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialTopical anaesthesia of gingival mucosa by 5% eutectic mixture of lignocaine and prilocaine or by 10% lignocaine spray.
The analgesic effect of topical application of local anaesthetics on the gingival mucosa and the absorption of the local anaesthetics into the blood were investigated in healthy volunteers by using a 5% eutectic mixture of the local anaesthetics lignocaine (100 mg) and prilocaine (100 mg) plus emulsifier (EMLA) or 10% lignocaine (200 mg) spray (Xylocain). The pain threshold on labial gingiva was measured by using the stimulator of an EMG-apparatus and a pair of stimulating electrodes, specially constructed for this purpose. ⋯ In the dosages used, the absorption of the local anaesthetics was more rapid after the mixture application than after spray application. No toxic reactions occurred.

An unusual presentation of a plunging ranula is described which suggests that raised air pressures within the oral cavity may be an additional factor in its aetiology.
