Editor's Notes
- a. Removal of wax b. Removal of foreign body in the ear and nose c. Removal of granulations in the ear d. The probe end is used to probe polyp in the nose and ear e. The probe end can act as a cotton swab carrier and can clean the ear or apply medication.
- used to deliver dressings and medications into the ear. It can also be used to remove foreign bodies in the ear canal.
- a. To detect the type of hearing loss b. To make an approximate estimate of the degree of hearing loss.
- a. Siegelization b. Fistula test c. Examination of external ear canal and tympanic membrane. d. Instillation of medications.
- a. To test the patency of Eustachian tube b. To inflate the middle ear c. To instill medications in the middle ear d. To remove foreign bodies from the nose e. As a suction cannula.
- Examination of the external ear canal and tympanic membrane b. Removal of wax, foreign body, otomycosis or ear discharge c. In operative procedures like myringotomy, myringoplasty, stapedotomy, stapedectomy d. For transcanal injections
- 1. Harvesting temporalis fascia 2. M astoidectomy, tympanoplasty 3. In head and neck surgeries like tracheostomy and laryngofissure
- a. This is used to explore and palpate various structures in the middle ear and mastoid b. It can also be used to position the graft and place gel foam during tympanoplasty c. To locate the antrum d. Can be used as a cell seeker.
- Uses: a. To freshen the margins of tympanic membrane perforation b. For myringotomy incision c. Skeletonization of the handle of malleus d. To break the middle ear adhesions e. Dislocation of incudostapedial joint during stapedectomy and while drilling mastoid at the attic near ossicles. f. To incise the facial nerve sheath in facial nerve decompression
- a. External canal skin tympanomeatal incision b. Elevation of tympanomeatal flap during myringoplasty, Tympanoplasty c. Freshening the margins and undersurface of the perforation during myringoplasty and tympanoplasty d. To break middle ear adhesions, especially between handle of malleus and promontory as in a case of atelectasis e. To clear granulation tissue and cholesteaoma in certain hidden areas of the middle ear like facial recess and sinus tympani.
- a. To hold graft materials like temporalis fascia and transfer it from one place to another b. To hold and transfer gel foam and cotton pledgets c. To hold and transfer ossicles, teflon piston, grommet or TORP/PORP d. The upturned and downturned types are used to reach crevices and inaccessible areas in the middle ear and mastoid for the above purpos
- a. To remove granulation tissue, cholesteatoma, tympanosclerotic plaques from middle ear and mastoid cavity b. To take a biopsy from middle ear and mastoid cavity c. To hold and transfer ossicles in the middle ear d. The curved varieties are useful to reach crevices and inaccessible areas of middle ear.
- To cut stapedius tendon, tensor tympani tendon b. To cut middle ear adhesions c. To cut the freshened margins of the tympanic perforation d. To cut skin tags during transcanal incision e. To cut the chorda tympani nerve when required.
- a. Diagnostic: Anterior rhinoscopy—nasal septum, Little’s area, lateral wall of nose, nasal cavity b. Therapeutic: removal of foreign bodies, antral wash, nasal packing, surgical procedures inside the nose
- a. Septoplasty/SMR b. Polypectomy c. Deep foreign bodies removal.
- a. To elevate mucoperichondrial and periosteal flap in septal surgeries b. For displacement of inferior turbinate in antrostomy operation c. For elevating canal skin and cartilage perichondrium in mastoid surgeries d. For elevation of mucosa in Caldwell-Luc operation e. To spread and tease temporalis fascia graft f. To perform uncinectomy.
- knife that can rotate 360 degrees within its two prongs. Hence, it can be positioned without rotating the instrument and the direction can be changed. This instrument is used in submucous resection of septum and also to harvest cartilage for rhinoplasty and tympanoplasty
- a. R emoval of maxillary crest and spur in septal surgeries. b. Opening the bone of the canine fossa in Caldwell-Luc surgery.
- Color code for endoscopes: 1. 0 degree : Green 2. 30 degree: Red 3. 45 degree: Black 4. 70 degree: Yellow
- It has an eye at the upper jaw to permit proper visualization
- higher up in the nasal cavity and the lateral wall of the nose
- cuts cleanly through tissue to help avoid tearing.
- a. Uncinectomy b. Widening the maxillary sinus ostium—
- a. It is used for removal of tissue from maxillary sinus b. Endonasal removal of cysts and polyps c. R emoval of foreign bodies from hypopharynx d. R emoval of ethmoidal air cells.
- a. R emoval of lacrimal bone in endoscopic dacryocystorhinostomy b. R emoval of anterior wall of sphenoid sinus c. R emoval of medial wall of maxilla d. Caldwell-Luc operation
- trace the path of the canaliculus
- helps to keep the mouth open and push the tongue up and away from the operation site a. Tonsillectomy b. Adenoidectomy c. Surgeries of palate and nasopharynx d. Excision of choanal polyp
- held like a dagger used to curette the adenoids by a blind technique. By sweeping movement. During the procedure, the neck of the patient should not be in too much extension as it might injure the atlanto-occipital joint.
- used to remove remnants of adenoid tissue after adenoidectomy
- grasp the tonsil and pull it medially during tonsillectomy.
- hold the tonsil to pull it medially prior to dissection.
- blunt end used for initial atraumatic dissection of the tonsil. The retracting end is used to retract the anterior pillar to look for bleeding points and tags of tonsillar tissue left behind
- used to snare the lower pole of the tonsil after dissection. The lower pole is crushed on snaring and thromboplastin is released which is a powerful vasoconstrictor.
