Presentation Transcript

  1. HEENT Illustrations Retina and Tympanic Membrane Slides are Presented with Permission From Welch Allyn, Inc.

  2. HEENT Illustrations • Eye & Ear colored pictures with permission from Welch Allyn, Inc.(more examples on reference CD-ROM) • Mouth diagrams adapted from “MediClip: The Complete Medical Art Library,” CD-ROM from Williams & Wilkins

  3. Eye: Anatomical Landmarks

  4. Lacrimal Apparatus • Tears flow from • Lacrimal gland to • Nasolacrimal duct

  5. Eye: Aqueous Humor & Venous Drainage • 1 Cornea • 2 Anterior Chamber • 3 Canal of Schlemm • 4 Ciliary Body • 5 Iris • 6 Lens • 7 Posterior Chamber • 8 Venous Drainage

  6. Depth of Anterior Chamber • Shine light across cornea & anterior chamber • Normal depth shows no shadow • A crescent shadow on opposite side indicates shallow anterior chamber & possible narrow angle glaucoma

  7. Eye Anatomy • Diopter focus • 0 diopter lens (retina) • +lens (anterior) • -lens (posterior)

  8. Refraction • Normal eye: focus is on retina: Use O Diopter, or straight lens • Myopia (nearsightedness): eye globe is long: focus is in front of retina: use - lens (concave lens) to compensate

  9. Refraction • Hyperopia (farsightedness): eye globe is short: focus is behind retina: use + lens (convex) to compensate • Astigmatism: focus is variable & irregular

  10. Systematic Assessment of Retina • Optic disk diameter 1.5 mm, with cup-to-disk ratio from 0.1 - 0.5 • Macula (size of disk), avascular with darker, depressed center (fovea) • Vessel: arteries brighter & thinner than veins, with diameter ratio of 2:3 • Inspect superior, inferior, temporal & nasal quadrants

  11. Normal Retina

  12. Hypertensive Retinopathy

  13. Hypertensive Retinopathy:

  14. Retinal Detachment

  15. Glaucoma

  16. Tympanic Membrane Left Ear

  17. Perforation

  18. Acute Otitis Media

  19. Serous Otitis Media

  20. Geographic Tongue • Benign variation of smooth tongue & raised papillae • Map like appearance • See text for photo

  21. Hair Tongue • Black hairy tongue • Elongated, darkened papillae • Often due to staining, infection or antibiotic treatment • Benign • See text for photo

  22. Lichen Planus • Benign, painless, white, lace-like eruptions • Bilateral on buccal mucosa • See text for photo

  23. Leukoplakia • Precancerous, white plaques on buccal mucosa, gingivae or tongue • Hairy leukoplakia of tongue associated with HIV • See text for photo

  24. Sinus Locations • 1. Frontal • 2. Ethmoid • 3. Maxillary • Sphenoid lies behind • Ethmoid

  25. Non-allergic Rhinitis • Nasal mucosa & lateral turbinates are erythematous with drainage

  26. Allergic Rhinitis • Nasal mucosa & lateral turbinates are edematous & pale with watery drainage

  27. Nasal Polyps • Nasal mucosa develops bulging sacs

  28. Lymph Node Groups: Neck Area • 1. Pre-auricular • 2. Post-auricular • 3. Occipital • 4. Tonsillar • 5. Submaxillary • 6. Submental • 7. Superficial cervical (deep certical under sternocleidomastoid muscle) • 8. Posterior cervical • 9. Supraclavicular • 10. Infraclavicular

  29. Thyroid • 1. Larynx & Thyroid Cartilage • 2. Trachea • 3. Thyroid lateral lobes • 4. Isthmus • 5. Sternocleidomastoid muscle
