Instruments Used The Ent Examination

Fig. 1.1 The instruments needed for an ENT examination: The laryngeal and postnasal mirrors require warming to avoid misting, and hot water or a spirit lamp is necessary. An angled tongue depressor or wooden spatula is needed for examining the oropharynx and postnasal space. Angled forceps are used for dressing the nose or ear. A tuning fork is essential for the diagnosis of conductive or sensorineural (perceptive) hearing loss. A C1 or C2 (256 or 512 cps) is needed. The very large tuning forks used to test vibration sense are unsatisfactory, and may give a false Rinne test. AJobson-Horne probe is widely used in ENT departments. A loop on one end is for removing wax (and foreign bodies) from the ear or nose. Cotton wool attached to the other end is used for cleaning the ear.

An auriscope, nasal and aural specula complete the basic instruments. A sterile swab and media are necessary for throat, nasal, or ear specimens to be taken for culture and sensitivity. A "narrow" swab holder as shown here is extremely useful for aural specimens, as the more common swab is too wide and can be traumatic for the deep meatus and middle ear.

Headlamp Used Indirect Laryngoscopy
Fig. 1.2 Lighting. The head mirror (a) gives effective lighting for examining the upper respiratory tract and ear, and leaves both hands free for using the instruments. Initially, the technique of using a head mirror is not easy, and some may prefer a fiberoptic or electric headlight (b).
Nasopharyngeal Swab Technique

Fig. 1.3 Rigid and flexible fiberoptic endoscopes.

These are important additional examination instruments. The flexible endoscope is of value to see the laryngeal region (see Fig. 1.62) in those with a marked gag reflex in whom indirect laryngoscopy (see Fig. 1.61) with a mirror is difficult. The rigid endoscope is important in examination of the nasal cavities.
