What is a Microstomia?

Definition and history Microstomia is the term used to describe a congenital or acquired reduction in the size of the oral aperture that is severe enough to compromise cosmesis, nutrition, and quality of life.

What cause microstomia?

The major causes of microstomia are chemical burn with caustic soda material, trauma, and skin cancer excision [1-5,7-9]. If the mouth sustains trauma or a chemical burn, the size of the oral opening can become smaller and dysfunction of mouth opening can occur.

What is burn repair surgery?

The goals of reconstructive burn surgery are to improve both the function and the cosmetic appearance of burn scars. This involves altering scar tissue, with both non-operative and operative treatment. The relationship between the burn patient and the reconstructive burn surgeon often lasts many years.

What does oral aperture mean?

Mouth: The oral aperture that opens into the oral cavity proper [Standing, 2005]. The opening is bounded by the upper and lower vermilion. The cavity comprises the alveolar arches with gums and teeth, the hard and soft palate, and the tongue, anchored to the floor of the mouth (Fig. 2).

What causes difficulty opening mouth?

Trismus occurs when a person is unable to open their mouth more than 35 millimeters (mm) . It can occur as a result of trauma to the jaw, oral surgery, infection, cancer, or radiation treatment for cancers of the head and throat.

What is a small mouth called?

Microstomia is a small mouth (micro- a combining form meaning small + -stomia a combining form meaning mouth = (abnormally) “small mouth” in Greek.)

How much does reconstructive burn surgery cost?

Scarring and disfigurement: $28, 000 to $35, 000. Psychological treatment: $16, 000 to $75, 000. Fragile skin or skin breakdown: $38, 000 to $107, 000. Skin grafts and delayed wound healing: $37, 000 to $110, 000.

When does a burn require surgery?

Burns that involve the face, hands, feet, genitalia or major joints. Third-degree burns, which can appear whitish, charred or translucent with no pinprick sensation in the burned area. Burns that cover more than 10 percent of total body surface area. Electrical or chemical burns.

What part of the eye is the aperture most like?

pupil
The aperture is like the pupil of your eye.

What is a fast shutter speed?

A fast shutter speed is typically whatever it takes to freeze action. If you are photographing birds, that may be 1/1000th second or faster. However, for general photography of slower-moving subjects, you might be able to take pictures at 1/200th second, 1/100th second, or even longer without introducing motion blur.

What to do if you cant open your mouth all the way?

Some treatment options include:

1. Use of a jaw-stretching device. These devices fit between the upper and lower jaw.
2. Medication.
3. Physical therapy that involves massaging and jaw stretching.
4. A change to a predominately soft-food diet until symptoms improve.

Why is one side of my jaw harder to open?

When the temporo-mandibular joint is out of position and asymmetric, the jaw may reach its maximal movement on one side before the other side can. This causes the entire mouth to open less wide. In arthritis conditions or with longstanding TMJ disorders, the jaw joint may become damaged.

Is commissuroplasty a viable treatment for microstomia after facial burns?

Conclusion: Commissuroplasty is an early functional post-burn corrective procedure that often must be performed prior to completion of scar maturation. Mucosal advancement flaps are a viable procedure for the treatment of microstomia after facial burns, resulting in good aesthetic and functional outcome.

What is micromicrostomia?

Microstomia is a contracture of the mouth, particularly at the oral commissure, caused by perioral facial burns. The most common of these burns results from electrical burns sustained when a child chews on an electrical cord or extension cord plug.

What is microstomia and how is it related to tumor resection?

The degree of microstomia is proportional to the extent of tumor resection, and it is a necessary tradeoff for using lip tissue for reconstruction after lip resection. Jane A. Petro MD, FACS, Zahid Niazi MD, FRCSI, FICS, FNYAM, in Plastic Surgery Secrets Plus (Second Edition), 2010 21 What is microstomia?

What is the pathophysiology of macrostomia?

Macrostomia is caused by rapid contraction of open wounds or grafts in the cheek and perioral region, resulting in eversion of the upper and lower lips and lateral movement of the oral commissures ( Fig. 50.16 ).
