Otologic surgery anatomy

Otologic Surgery-Anatomy


External ear auricle pinna

External ear- Auricle (pinna)

  • Concentrates sound waves and conducts them into the external auditory canal

    • Flexible cartilage covered with thick skin

    • One on each side of head helps judge direction of sounds

    • Shape of auricle helps differentiate between sounds in front or back


External auditory canal

External auditory canal

  • S-shaped pathway about 2.5 cm long

  • Made up of bone and cartilage, covered by soft, sensitive skin

  • Cerumen- waxy substance

    • Protects and lubricates canal

    • Secreted by sebaceous glands in the distal third of the canal

    • Helps trap foreign materials and reduce bacterial levels


Tympanic membrane eardrum

Tympanic Membrane (eardrum)

  • Comprised of three layers

    • Outer layer- epithelium

    • Middle layer- fibrous connective tissue

    • Inner layer- mucous membrane

  • Is disc shaped, concave, translucent gray, with a diameter of about 1 cm

  • Protects the middle ear


Middle ear

Middle ear

  • Filled with air from the nasopharynx via the Eustachian tube

  • Communicates with the mastoid air cells of the temporal bone


Middle ear1

Middle ear


Middle ear2

Middle ear

  • Mucous membrane of the middle ear is continuous with that of the pharynx and mastoid cells, making it possible for infection to travel to the middle ear (otitis media) and the mastoid cells (mastoiditis)


Middle ear3

Middle ear

  • Ossicles- a chain of 3 tiny, moveable bones that extend across the middle ear, from the tympanic membrane to the oval window

    • Malleus (hammer)

    • Incus (anvil)

    • Stapes (stirrup)

    • Moveable joints allow the ossicles to transmit sound across the middle ear


Conduction

Conduction

  • Tympanic membrane

  • Malleus

  • Incus

  • Stapes

  • Oval window

  • Fluid of cochlea

  • Round Window

  • Hair Cells of the organ of Corti


Middle ear4

Middle ear

  • Oval window- an oval shaped aperture in the wall of the middle ear leading to the inner ear. The footplate of the Stapes vibrates in the oval window, transmitting sound waves to the cochlea.


Middle ear5

Middle ear

  • Round window- below the oval window. Round opening in the medial wall of the middle ear leading into the cochlea and covered by a membrane called the secondary tympanic membrane


Inner ear labyrinth

Inner ear (labyrinth)

  • Bony labyrinth

  • Membranous labyrinth


Inner ear labyrinth1

Inner ear (labyrinth)

  • Bony labyrinth- filled with watery fluid (perilymph) that surrounds and bathes the membranous labyrinth

    • 3 divisions

      • Cochlea

      • Vestibule

      • Semicircular canals


Inner ear labyrinth2

Inner ear (labyrinth)

  • Cochlea- tubular shaped, resembling a snail shell

    • Organ of Corti- neural end organ for hearing

      • Neuroepithelium- projects thousands of hair cells that convert the wave motion into electrochemical impulses

  • Connected to the brain by the 8th cranial nerve (vestibulocochlear or acoustic)


Inner ear labyrinth3

Inner ear (labyrinth)

  • Vestibule-contains 2 sacs, utricle and saccule, which are gravity oriented and concerned with static equilibrium

  • Semicircular canals- 3- lateral, superior, and posterior canals, at approximate right angles to each other

    • Controls equilibrium during movement


Inner ear labyrinth4

Inner ear (labyrinth)

  • Membranous labyrinth- within it lie four (4) structures: the cochlear duct, utricle, saccule, and the semicircular ducts

    • Endolymph bathes and nourishes the sensory cells contained within the membranous labyrinth

M ni re s disease

Ménière’s disease

  • Recurrent and usually progressive group of symptoms including:

    • Progressive deafness

    • Ringing in the ears

    • Dizziness

    • Sensation of fullness or pressure in the ears

  • Attacks occur suddenly and may last as long as 24 hours


M ni re s disease1

Ménière’s disease

Normal Membranous Labyrinth

Dilated Membranous Labyrinth

in Ménière’s disease (Hydrops)


M ni re s disease2

Ménière’s disease

  • When one ear is affected, the other will also become involved in approximately 50% of cases

  • Etiology is unknown, but edema of the membranous labyrinth has been found in autopsies

  • TX- bed rest, antihistamines, sedatives, discontinuation of smoking, and, rarely, surgery


Considerations

Considerations

  • Gloves must be powder free to prevent granuloma formation, which could lead to irreversible hearing loss

  • Operating microscope is used routinely, and handles or a drape will be needed


Considerations1

Considerations

  • Pass instruments in a manner to allow the surgeon to remain focused on the operative site

  • Instruments are delicate, and must be handled carefully to avoid damage


Considerations2

Considerations

  • When using a burr to remove bone constant irrigation is needed to combat heat buildup and bone dust accumulation


Considerations3

Considerations

  • Multiple suction tips must be available, as they are so fine they clog frequently

  • A nerve stimulator should be available

  • Hemostasis may be accomplished with epinephrine, gelfoam or bone wax


Anesthesia

Anesthesia

  • Local anesthesia may be used for minor procedures on the external ear, or for procedures in which the doctor wants to test the patients hearing during the procedure


Anesthesia1

Anesthesia

  • General anesthesia is used to prevent patient movement on procedures involving the fine structures of the middle or inner ear


Anesthesia2

Anesthesia

  • In the absence of inflammation the mastoid bone lacks sensation, except for the outer periosteum, so a local anesthetic may be used


Positioning

Positioning

  • Patient should be supine with the operative ear up

  • Dependent ear should be protected from pressure with a donut or similar headrest


Ent

Prep

  • Hair may be shaved or clipped if necessary, and/or plastic drapes may keep the field free from hair

  • Prep the auricle and periauricular skin

  • Meatus may be prepped with a swab if the eardrum is not perforated


Draping

Draping

  • Should be lint free to prevent granuloma formation

  • Plastic aperture drapes are common, and may be placed before or after the prep

  • Triangle off with 3 towels, and a fenestrated drape may be placed

  • Split sheets may also be utilized


Incisional approaches

Incisional approaches

  • Endaural- incision is made near the meatus

    • Offers direct access to the canal and tympanic membrane, or for stapes surgery


Incisional approaches1

Incisional approaches

  • Transcanal- incision is made in the tympanic membrane, through the canal

    • For surgery on the tympanic membrane or the ossicles


Incisional approaches2

Incisional approaches

  • Postauricular- incision is made behind the ear, following the posterior auricular skin fold

    • Used for procedures on the mastoid, middle, and inner ear


Surgical interventions

  • Common pediatric problem


Myringotomy1

Myringotomy

There are a variety of PE tubes to choose from, depending on the length of time the doctor wants them to stay in.


Myringotomy2

Myringotomy

  • Care must be taken to avoid getting water in the ears while the tubes are in place

  • Myringotomy knife, alligator forceps, and microscope

  • Once the tube falls out, the incision usually heals


Tympanoplasty

Tympanoplasty

  • Surgical repair of the tympanic membrane

  • Usually for perforation of the ear drum resulting from direct injury, blow to the ear, tears from temporal bone fractures, and lightning injury


Tympanoplasty1

Tympanoplasty

Mastoidectomy

  • General anesthesia usually, but can use local

  • Postauricular or endaural incision

  • Use a burr to remove diseased bone

  • Simple mastoidectomy- removal of the air cells
