Study Notes
Nasal Endoscopes
- Used to visualize the nasal cavity and sinuses
- Types:
- Rigid nasal endoscopes: provide high-resolution images, but have a limited field of view
- Flexible nasal endoscopes: offer a wider field of view, but lower image resolution
- Features:
- Illumination: usually via a light source or fiber optic cable
- Angled or curved tips for navigating nasal passages
- Optional: suction, irrigation, or biopsy channels
- Indications:
- Diagnosing nasal polyps, tumors, or other abnormalities
- Guiding surgical procedures, such as polyp removal or turbinate reduction
Otoscopes
- Used to examine the external ear canal and tympanic membrane
- Features:
- Magnification: typically 2-3x
- Illumination: via a built-in light source or fiber optic cable
- Optional: speculum or ear specula for examining the ear canal
- Types:
- Diagnostic otoscopes: for routine ear exams
- Surgical otoscopes: for minor procedures, such as ear wax removal
- Indications:
- Diagnosing ear infections, wax impaction, or other ear-related conditions
- Monitoring ear drum movement and middle ear function
Ear Suction Devices
- Used to remove ear wax, debris, or other material from the ear canal
- Types:
- Suction pumps: create a vacuum to remove material
- Irrigation devices: use a gentle flow of water or saline to remove debris
- Features:
- Gentle suction or irrigation to avoid damaging the ear drum
- Adjustable suction or flow rates
- Optional: built-in illumination or magnification for visualization
- Indications:
- Removing ear wax or debris
- Preparing the ear canal for further examination or procedures
Laryngoscopes
- Used to visualize the larynx (voice box) and surrounding structures
- Types:
- Direct laryngoscopes: provide a direct view of the larynx
- Indirect laryngoscopes: use a mirror or prism to reflect the image
- Features:
- Illumination: usually via a light source or fiber optic cable
- Optional: suction, irrigation, or biopsy channels
- Indications:
- Diagnosing vocal cord lesions, polyps, or other laryngeal abnormalities
- Guiding surgical procedures, such as tumor removal or vocal cord injections
Nasal Endoscopes
- Visualize the nasal cavity and sinuses
- Two types: rigid (high-resolution images, limited field of view) and flexible (wider field of view, lower image resolution)
- Features: illumination via light source or fiber optic cable, angled or curved tips, optional suction, irrigation, or biopsy channels
- Used for diagnosing nasal polyps, tumors, or other abnormalities, and guiding surgical procedures like polyp removal or turbinate reduction
Otoscopes
- Examine the external ear canal and tympanic membrane
- Features: 2-3x magnification, illumination via built-in light source or fiber optic cable, optional speculum or ear specula
- Two types: diagnostic (routine ear exams) and surgical (minor procedures, e.g., ear wax removal)
- Used for diagnosing ear infections, wax impaction, or other ear-related conditions, and monitoring ear drum movement and middle ear function
Ear Suction Devices
- Remove ear wax, debris, or other material from the ear canal
- Two types: suction pumps (create a vacuum) and irrigation devices (gentle flow of water or saline)
- Features: gentle suction or irrigation, adjustable suction or flow rates, optional built-in illumination or magnification
- Used for removing ear wax or debris, and preparing the ear canal for further examination or procedures
Laryngoscopes
- Visualize the larynx (voice box) and surrounding structures
- Two types: direct (direct view) and indirect (use a mirror or prism to reflect the image)
- Features: illumination via light source or fiber optic cable, optional suction, irrigation, or biopsy channels
- Used for diagnosing vocal cord lesions, polyps, or other laryngeal abnormalities, and guiding surgical procedures like tumor removal or vocal cord injections
Otolaryngology Instruments
Nasal Endoscopes
- Visualize the nasal cavity and sinuses
- Flexible or rigid tubes with a camera and light on the end
- Flexible nasal endoscopes: used for office procedures, can be bent to navigate through nasal passages
- Rigid nasal endoscopes: used for surgical procedures, provide a more detailed view
- Diagnose nasal polyps, tumors, and sinus infections
- Remove foreign objects or nasal polyps
- Guide surgical procedures
Ear Suction Devices
- Remove earwax, debris, and fluids from the ear canal
- Suction otoscopes: combine suction device with otoscope for visualization
- Ear suction units: standalone devices with suction tube and collection container
- Remove earwax or debris causing hearing loss or discomfort
- Clean the ear canal before ear exams or procedures
- Remove fluids or blood from the ear canal
Otoscopes
- Visualize the ear canal and eardrum
- Standard otoscopes: used for routine ear exams
- Pneumatic otoscopes: test for eardrum mobility and middle ear function
- Video otoscopes: capture images or video of the ear canal and eardrum
- Diagnose ear infections, eardrum perforations, or earwax buildup
- Monitor ear health and detect abnormalities
Laryngoscopes
- Visualize the larynx (voice box) and vocal cords
- Indirect laryngoscopes: use mirror and light source to reflect the larynx
- Direct laryngoscopes: use tube with camera and light source to directly visualize the larynx
- Flexible laryngoscopes: used for office procedures, can be bent to navigate through nasal passages
- Diagnose vocal cord lesions, polyps, or cancer
- Evaluate vocal cord function and movement
- Guide surgical procedures of the larynx
