-Compresses (saturated with autopsy gel or cavity fluid)
-Temporary sutures (bridge or loop)
What are the general procedures for preparing large cavities and excision sites? Before embalming?
-Additional applications of cavity packs or autopsy gel
-Allow at least 4 hours for tissue to dry (8 to 10 is ideal)
What are the general procedures for preparing large cavities and excision sites? After embalming?
Trim the edges of the wound by undercutting; the undercutting will help hold the wax in place
Describe the procedures for undercutting the edges of a wound?
-Cotton and plaster
-Cotton and sealer
-Mastic or Mortuary putty
-Plaster of Paris
List the materials that may be used to fill cavities and deep wounds?
Clear nail polish
-Varnish or shellac
-Rubber or cement
What are the substitutes that may be used for sealer?
Apply the liquid sealer to the inner margins of the wound (not the skin). When using a casket weave, be sure to suture the deep tissue (under the skin) not the surface margins of the skin
Describe the method for filling a wound.
Any support or framework (beneath the surface) employed in restorative art
Define an armature
-Wire (strand or mesh)
-Cotton saturate with liquid sealer
-Cotton saturated with plaster of Paris
What materials can be used for an armature?
1. Basket-weave suture
2. Loop stitch suture
3. Bent wire armature
4. Wax support
What are four methods for attachment and support of the ear?
-Used after embalming for deep wound excisions
-Will maintain the position of the free margins of the skin
-Used to provide an anchor and support for wax (wound filler)
Describe a basket weave suture. Is it temporary or permanent?
-Primarily used before embalming to bring together the free margins of a large wound or cavity
-Several individual loops
-The loops are tied loosely
-The suture is NOT pulled tight against the skin
Describe a loop stitch suture. Is it temporary or permanent?
-Any artificial support or framework used in a restoration
-When an ear is missing, an armature of firm wire (a coat hanger will do) may be inserted under the skin
-The central part of the wire is bent to conform to the curvature of the ear
-The ends of the wire are forced though the skin to lie flat against the underlying bones
-A wire armature may also be used to form the bridge of the nose
Describe a bent wire armature.
-Wax support, wax foundation, wax construction
-All parts reconstructed are support by wax and constructed from wax
-The wax support helps to hold the artist reconstruction in place and aids in the fusion and blending of the real and he artificial parts
What type of support and attachment will we use for lab projects?
1. Basket weave suture
2. Plaster of Paris and cotton
3. Cotton and liquid sealer
4. Wire screen
5. Wire armature
6. Cardboard armature
7. Cotton cylinders
8. Wax support
What materials may be used for support and attachment of the nose?
Describe the most common bent wire armature of the nose.
Thin cardboard is folded and trimmed to resemble the nasal projection. They may require sutures to hold in place and a tent of cotton and sealer map be applied
Describe the most common cardboard armature of the nose.
Wire screen such as window screen or hardware cloth because they form the dome of the nasal cavity. The edges are forced into or beneath the margins and the may require sutures to hold in place.
Describe the most common screen armature of the nose.
This is used only when the lower part of the nose is reconstructed. Two or three cotton cylinders are pushed behind the nasal bones
Describe the most common cotton cylinder armature of the nose.
How much "artistry" is a part of our work?
How much geometry and structure is a part of modeling?
Because the body will be in repose
Why is it important to view your work from different angles and different lighting?
Yes because the more often we attempt at the same feature, the easier it becomes
Is repetition important in learning to model facial features?
It can be smoothed with your hand or with a thin coat of petroleum jelly or massage cream on your fingers or instruments (or on the wax).
What are some methods for smoothing the surface of our wax?
1. Zygomatic arch
2. Mastoid process
3. Mandibular fossa
4. External auditor meatus
Name four anatomical structures for positioning the ear.
To the posterior 2/3rds of the base of the nose, and are oblique to each other, they must not extend into the protruding lobe.
What are the openings for the anterior nares located?
To avoid the upturned nose (pug nose)
Why it is important to make sure the bottom of the nose is at a right angle to the profile of the face?
If the teeth are present, the inside of the mouth should be dried chemically and the marginal tissues sutures with a basket weave. If the teeth are absent, deep filler may be applied to the depth of the marginal tissue
If the lips are reconstructed, what is the treatment for the inside of the mouth?
The lower mucous membrane but it recedes slightly in profile
Which is thicker, the upper or lower mucous membrane?
It is triangular in shape
In youth, what is the geometric of the angulus sulcus?
With a straight pin or a needle
How may the vertical lines of the lips be reproduced?
Yes as well as in front view
Is the profile view of the eye important?
Treat the opening as a cavity wound before attempting restoration; use cavity packs or gel. The treatment is similar to eye enucleation procedures. Be sure the eye socket is clean and dry and sealed before restoration.
If there is no eyeball, what is the treatment for the socket of the eye?
How is the shape of the eye described?
Gentle dipping curve
Describe the line of eye closure.
