Clotting disorders in HOF: assessing bleeding risk

Most orofacial harmonization (HOF) patients are healthy, and the question about clotting seems remote. But hematoma is the most frequent local complication of injectables, and a clotting abnormality, known or not, can turn an expected bruise into bleeding that is hard to control, with tense swelling and risk to neighboring structures.

This page lays out risk assessment as decision support. It does not guide medication adjustments, does not define test values and does not replace the assessment of the treating physician, who leads the investigation and treatment of clotting disorders.

What are clotting disorders?

Broadly speaking, hemostasis depends on platelets, clotting proteins (factors), intact vessels and a balance between forming and dissolving clots. Changes in any of these elements can raise the risk of bleeding. For the practice, the essential thing is to recognize the sources of risk:

Details on medications and supplements are in anticoagulants and injectable procedures, anti-inflammatories and hematoma in HOF and supplements and hematoma risk in HOF.

Why does bleeding matter in the face?

The face is highly vascularized and has spaces where blood can pool. Besides the aesthetic discomfort (ecchymosis and hematoma), heavier bleeding can:

• increase swelling and pain;
• compress nearby structures, such as in the periorbital area;
• make it harder to assess a possible vascular complication, since bruising and swelling mask signs;
• raise the risk of infection and of residual pigmentation (see residual pigmentation after ecchymosis);
• rarely, progress to an expanding hematoma (see expanding hematoma in the face).

That is why clotting is part of the safety assessment, and not only an aesthetic matter.

What should you ask in the medical history?

A targeted medical history in HOF is the most useful screening tool. Ask in simple terms and document the answers.

Positive answers do not mean automatic refusal, but they indicate that the case calls for a conversation with the treating physician, an adjusted plan and specific consent. If the patient cannot say, ask them to bring a report or prescription to the next visit, instead of assuming that "everything must be fine".

What about tests?

Clotting tests are not routine for every HOF patient. They come into play when the history suggests an abnormality or when the treating physician considers them necessary. The physician is the one who orders, interprets and decides on the course of action based on the tests, and the HOF professional should respect that flow.

What falls to the practice is to:

• identify the sign in the medical history and the examination;
• request an assessment from the treating physician, with clear information about the planned procedure;
• wait for clearance, which should come in writing or be recorded in the patient record;
• adapt the plan according to the guidance received.

Never "test" a patient with a suspected disorder by performing a minor procedure to see whether they bleed. The risk is the patient's.

How should the plan be adapted?

When the risk is increased but the procedure is considered acceptable, the plan tends to be more conservative:

The choice of technique and material belongs to the qualified professional, according to the assessment and the instructions for use. See cannulas and needles and cannula gauge and length for the general debate, without implying that any device eliminates the risk.

When should you contraindicate or postpone?

In general, you postpone or contraindicate when:

• there is a clotting disorder that has not been investigated or is uncontrolled;
• the patient has active bleeding, very low platelets or an acute illness;
• the treating physician does not give clearance or recommends waiting;
• the procedure is purely elective and the risk outweighs the perceived benefit;
• the patient does not accept the terms of the plan or does not commit to follow-up.

The decision must be clearly documented. See general contraindications in HOF and saying no to a patient with a contraindication. For the patient's question in written form, see clotting disorder and fillers.

What about communication and documentation?

Explain to the patient, without alarmism, that clotting influences the risk of bruising and that the plan will be adjusted. Record in the patient record the history, the conversation with the physician, the decision, the plan and the instructions. The informed consent should state the increased risk specifically.

In Harmy, planning by area, in ml, and the illustrative projection made from the frontal photo help organize a plan in stages, which is useful for higher-risk patients. The projection, however, is only an illustrative simulation, not a promise of results: the safety of the procedure depends on clinical assessment.
