Bronchoscope passed through speculum. extended at the occipito-atloid and atlo-axoid joints. The extension of theneck should not make a curve distributed along the whole cervical head while resting on the head-extension of the table should still be con-trolled and rest in the hands of an assistant. The illuminated slide speculum is passed into the mouth directly in themedian line close to the dorsum of the tongue until its tip has just passed theepiglottis. The tip is then tilted strongly forward by lifting the Fig. 900.— removed, leaving bronchoscope in position. This presses forward the epiglottis and the base of the tongue and exposesthe glottic aperture (Fig. 898). The bronchoscope is lightedand passedthrough the speculum into the trachea (Fig. 899). The speculum is thenremoved, and the bronchoscope passed to the desired point (Fig. 900).Care should be taken in first introducing the instrument that it is not passedtoo far beyond the epiglottis. The closure of the upper esophageal orificeby the pharyngeal constrictors may be mistaken for the glottic orifice, and theinstrument passed into the esophagus. TREATMENT OF INJURIES AND DISEASES OF THE HEAD 243 The instrument can be made to enter either bronchus by swinging it toone side. Secretion which is in the way may be sponged out, or if excessiveit may be aspirated through a rubber tube. The lamp, becoming coveredwith blood or dimmed by some other means, may be removed and cleanedwithout withdrawing the broncho
