Shaping the Gap Before Surgery
Anatomical domain · Lesson 7 of 20 · Human Body Systems (HBS)
Today's goal: Explain how nasoalveolar molding narrows the alveolar gap and improves nasal symmetry before lip repair, and weigh the strength of the evidence behind it.
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.
I recommend starting NAM for Mateo. Benefit: an evidence review finds NAM reduces deformity severity before surgery and may lower the need for revision, and a long-term cohort found 57 percent of children who had a gum procedure avoided a later bone graft. Limitation: I will be honest that the evidence is modest, since benefits are confounded by surgery type and timing, and a bilateral systematic review found the quality too low to be definitive. Family demand: NAM needs weeks of frequent clinic visits and committed daily care, so we will set up support before we start, and my recommendation is yes.
This model shows the level of evidence and organization needed to complete: An evidence-weighted recommendation that names a benefit, a limitation, and a family demand.
- Write one defensible claim.
- Choose specific evidence that supports the claim.
- Explain the scientific rule that connects the evidence to the claim.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
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: Does the guide permanently join the pieces?
- 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: Present to the team in four sentences whether to start NAM for Mateo: (1) name at least one concrete benefit with its source, (2) state honestly one limitation of the evidence with its source, and (3) note one practical demand NAM places on the family. End with a clear recommendation, not a hedge.
- 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 "Present to the cleft team in four sentences whether to start NAM for Mateo: (1) name at least one concrete benefit with its source, (2) state honestly one limitation of the evidence with its source, and (3) note one practical demand NAM places on the family. End with a clear recommendation, not a hedge.".
- 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.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Distinguishing what NAM does from how strong the evidence is.
- 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.
