Sense Organs • Eye – sends visual images to the brain for interpretation as pictures • Ear- sends sound waves to the brain • Nose – sends messages regarding airborne material. Also assists with sense of taste • Body system – 2 nd character -8 - Eye -9 – Ear, Nose and Sinus © 2012

Anatomy Review-Ocular System • Anterior cavity -Anterior Chamber -Posterior Chamber • • Posterior cavity Aqueous humor Vitreous Body See Figure 9. 1 © 2012

Ocular Structures • Ocular muscles -See Figure 9. 2 -ICD-10 -PCS classifies all eye muscles to extraocular muscles body part • Orbital structures -Lacrimal gland -See Figure 9. 3 © 2012

Anatomy Review- Ear • External ear – auricle -Pinna, ear lobe -External auditory canal • Middle ear -Eardrum -Ossicles one body part in ICD-10 -PCS • Malleus, incus and stapes -Air cells • Inner ear • See Figure 9. 4 © 2012

Anatomy Review - Nose • Nasal turbinates or conchae • Paranasal (accessory) sinuses -Ethmoid -Frontal -Maxillary -Sphenoid • See Figure 9. 5 and Figure 9. 6 © 2012

Common Root Operations • Alteration-for cosmetic purposes • Dilation, Occlusion, Restriction-tubular body parts • Extraction-lens removal only • Replacement-lens removal with IOL, cornea transplant © 2012

Common Root Operations (continued) • • • Repair-radial keratotomy Drainage-tympanoplasty, myringotomy Excision- removal of one ossicle Resection – removal of all three ossicles Inspection – diagnostic sinus endoscopy See Table 9. 1 © 2012
