Video Otoscopy
Norm of Video Otoscopy
Normal structure, absence of inflammation, infection, growths, or obstruction.
Usage of Video Otoscopy
Anatomy and physiology of the ear canal, visualization of the tympanic membrane. Any trauma causing bleeding may be diagnosed as well as vascular tumors of the middle ear. Using pneumatic video-otoscopy, the mobility of the tympanic membrane is observed. Video recordings can be made during surgery.
Description of Video Otoscopy
This technique combines the standard methods of ENT endoscopy with a small, hand-held, video camera for viewing and recording the examination and ENT procedure. It can be used with the ears, nose, or larynx. The advantage of the video is in the visual record of the anatomy and physiology, which can be carefully studied at a later time without further discomfort to the client. The video can also be used in consultations with other physicicans and can serve as an excellent teaching tool. The recording is stored as part of the client record.
Professional Considerations of Video Otoscopy
Consent form IS required.
Risks
Infection.
Contraindications
Sedatives are contraindicated in clients with central nervous system depression.
Preparation
- Obtain a video camera, a light source, a video cassette recorder, a video printer, a monitor and an enhancer, and film.
- Obtain an endoscope: Hopkins 4.0 mm for adults and Hopkins 2.7 mm for children.
- Use anesthetic spray and sedation as prescribed. Monitor respiratory status closely throughout the procedure if sedation is given.
- Obtain instruments to remove wax and superficial hairs from the ear.
- See Client and Family Teaching.
- Just before beginning the procedure, take a “time out” to verify the correct client, procedure, and site.
Procedure
- Wax and hair are removed.
- A topical anesthetic is applied to the canal.
- Sedatives may be given intravenously.
- The client is placed in an upright or supine position, and the endoscope is inserted.
- The video recording may begin at the time of insertion.
Postprocedure Care
- Continue the assessment of the respiratory status. If deep sedation was used, follow institutional protocol for post sedation monitoring. Typical monitoring includes continuous ECG monitoring and pulse oximetry, with continual assessments (every 5–15 minutes) of airway, vital signs, and neurologic status until the client is lying quietly awake, is breathing independently, and responds to commands spoken in a normal tone.
- Assess for postoperative complications, including bleeding and pain.
Client and Family Teaching
- The procedure should take less than 1 hour.
- The client should be very still during the procedure.
Factors That Affect Results
- The client must be able to sit still for an extended length of time.
Other Data
- Videos are also used in rhinoscopy and laryngoscopy.
