Describing the Cleft: Type, Side, and How Complete
Disease domain · Lesson 2 of 20 · Shared clinical backbone (the cleft team)
Today's goal: Students will classify a cleft by the structures involved (lip only, palate only, or both), by laterality (unilateral or bilateral, and which side), and by completeness (complete or incomplete), and apply that vocabulary to Mateo.
This is a model of the work you should turn in. Use it to check your own: match the structure and the level of detail, do not copy it. Your wording should be your own.
Mateo's standardized description box:
- Structures involved: both lip and palate (cleft lip and palate, CLP)
- Laterality (and side): unilateral, left side only (right lip intact)
- Completeness: complete (lip cleft reaches the left nostril; palate open along its full length)
- One-line summary: 'Complete unilateral (left) cleft lip and palate.'
Why a registry needs this: a registry compares thousands of children to study outcomes and plan surgery, and 'a cleft' could mean a tiny lip notch or a wide bilateral CLP; the three-axis phrase pins down exactly what a surgeon will repair.
This model shows the level of evidence and organization needed to complete: A filled chart/registry description box that classifies the cleft on all three axes plus a one-line summary.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Confirm no submucous-cleft features are being missed; here the cleft is overt, not occult.
Context note: Mateo's pattern is the most common version of each axis. CLP is the largest single cleft category (about 45%), unilateral lip clefts outnumber bilateral roughly 4 to 1, and of unilateral clefts about 70% are left-sided. His phenotype is typical, not unusual; this is a description, and it does not yet tell us a cause.
This model shows the level of evidence and organization needed to complete: A short note placing Mateo's phenotype against the cleft-type distribution.
- Date and label the entry.
- Record the procedure, observation, or design decision clearly.
- End with what the evidence means and the next step.

The finished product above did not appear all at once. Here is the path from the question to the turned-in work, so you can follow the same steps.
- 1Start from today's question: Which address details are independent?
- 2Work the Model and the Explore questions to reason it out before writing anything.
- 3Pull the specific evidence the product needs from the reading and any database you used.
- 4Write it up in the required format: Fill in Mateo's standardized description box for the chart and registry (structures involved, and side, completeness, one-line summary), then write one sentence on why a registry needs this level of precision and why a casual word like 'a ' will not do.
- 5Check it against the rubric, then submit.
| Criterion | Proficient | Developing | Beginning |
|---|---|---|---|
| Complete | Every required part of the artifact is present and filled in. | Most parts are present, but one is missing or left blank. | Several parts are missing. |
| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
| Submitted | Turned in through the route named under Submit here and confirmed. | Turned in, but in the wrong place or unconfirmed. | Not turned in. |
- CompleteProficient: Nothing is left blank: the model fills every part of "Fill in Mateo's standardized description box for the chart and registry (structures involved, laterality and side, completeness, one-line summary), then write one sentence on why a registry needs this level of precision and why a casual word like 'a cleft' will not do.".
- AccurateProficient: Every number and claim matches the case evidence.
- Scientific reasoning (CER)Proficient: It names a claim, cites the specific evidence, and explains the reasoning, not just the answer.
- Professional communicationProficient: It is organized and labeled like a real chart note.
- SubmittedProficient: It would be attached to your class form or handed in, and confirmed.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

It builds this reusable test skill: Classifying a cleft on the three axes of structures, laterality, and completeness.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
