Clue 1: Orient yourself
Which details let two people find the same place?
Use the labels and the picture's left-to-right, near-to-far, or before-and-after order. Name only what you can point to.
The question
Which details let two people find the same place?
Why it matters: Structure affects feeding, breathing, hearing, speech, teeth, and surgical planning. Care teams need to connect the exact structure to the function a child is using every day. Today you practice the professional reasoning behind that work: A useful cleft label records side, completeness, and anatomical extent without replacing the examination.

Mapping a described cleft to a standardized classification label
For life
To find the cause, change one thing and watch what changes.
Principle: Same look, different cause
Five principles we return to
Having it is not using it
Same instructions, different switches
Same look, different cause
Change one thing and watch

Try the everyday version first
A precise address compresses a route into shared coordinates
An address gives people a common way to describe one location. It replaces a long set of directions with agreed labels and boundaries.
Do not jump to the biology yet. Treat the picture as a small system. Track its parts, follow one change at a time, and keep more than one explanation open until the picture supplies a way to separate them.
Clue 2: Trace one change
What would be lost by writing only city?
Follow one object, stage, or path. Point to the first place where the situation changes instead of jumping to the ending.
Clue 3: Keep the cause open
Why must the map still be checked after reading the address?
List more than one explanation that still fits. Name the extra observation that would help you separate those possibilities.
Now inspect the illustration
Work from the visible evidence. A useful answer names the part of the picture that supports it and leaves unknown causes open.

Tier 1 check
Finish with the everyday model
Use the everyday picture to answer today's question in plain words: Which details let two people find the same place?
You can complete today's required check without opening the technical details below.
Ready for the real names? Optional tier 2
Technical rules and limits
Rule 1: State left, right, or bilateral.
Rule 2: State complete or incomplete.
Rule 3: Name the structures and use a system only within its scope.
Where the analogy stops: A clinical classification summarizes anatomy but cannot capture every three-dimensional feature or family priority.
Carry the previous idea forward
A cleft is not only a visible gap; it also redirects muscles and changes the forces they produce.
Today's technical takeaway
A useful cleft label records side, completeness, and anatomical extent without replacing the examination.
Now map the same rules onto biology

Mateo's case file: evidence supplied in this lesson
ANA04-E1
The opening is on Mateo's left side.
Why it matters: The cleft is unilateral left.
ANA04-E2
The cleft extends through the lip and alveolus into both hard and soft palate.
Why it matters: The cleft is complete and involves lip, alveolus, and palate.
ANA04-E3
Veau III describes a unilateral complete cleft involving the soft and hard palate and continuing through the alveolus on one side.
Why it matters: The palate component fits Veau III.
Make the clinical decision
You are completing the operative problem list.
Three labels are offered for the same composite examination.
AComplete unilateral left cleft lip, alveolus, and palate; Veau III.
BCleft palate, side and extent unknown.
CBilateral incomplete cleft lip only.
Choose the most precise supported label and cite all three evidence cards.

Before this page, you should know
- A is a gap left where tissues that should have joined during development did not (a failure of ).
- In a lip the ring is interrupted and its fibers run up the cleft margins instead of crossing the .
Today's new idea is only
A good turns a paragraph of description into one shareable label any team can read.
Goal: Use the Veau, LAHSHAL, and systems to classify a , and place Mateo as a complete left cleft of lip, , and ().
Know by the end
- An international survey of 197 providers found 18 systems in use, with ICD-10 (35.5%), LAHSHAL (34.0%), Veau (32.5%), and the striped-Y (22.8%) most common.
- Veau sorts clefts into four groups by which structures are clefted, divided at the , and acts as a rough severity proxy.
- LAHSHAL is a seven-letter string (Lip--Hard-Soft-Hard-Alveolus-Lip) that records side, extent, and completeness at once; capitals mean complete, lowercase mean incomplete.
- Mateo's is a complete left cleft of lip, , and , which is .
1
Why classify
Model start: A is an agreed shorthand so any team, anywhere, pictures the same defect from the label alone.
- Precise classification matters because it guides treatment planning and lets centers ____ their results.
2
Veau and LAHSHAL
- Veau divides clefts at the ____ foramen into four groups and works as a rough severity proxy.
- LAHSHAL uses ____ letters for complete clefts and lowercase for incomplete, so it captures side, extent, and completeness.
- Veau's weakness is that it does not record ____ (which side).
3
Placing Mateo
- Mateo's complete left of lip, , and is Veau ____.

- Skim the title and abstract first to get the gist.
- Circle the one sentence that states the main claim.
- Box the evidence the authors give for that claim.
- Mark one sentence that confuses you, and move on.

Evidence to produce
Classify Mateo three ways and write it into his chart: (1) Veau class with a one-sentence justification, (2) a LAHSHAL string filling the seven positions right-to-left (capitals for complete, a dot for intact, central soft palate clefted), and (3) a shaded striped-Y. Then write one sentence to a surgeon in another city using only your three labels.

Everything required for today's decision is already in the case file and plain-language explainer. The links below are original papers and database records for teachers and advanced readers, not assigned student reading.
- Claim: Mateo's is a complete left cleft of lip, , and , which is Veau ____.
- Evidence: State which structures are clefted and on which side, and show how that maps to the .
- Reasoning: Explain why a single precise label is more useful to a worldwide team than a paragraph of description.
How this is graded (rubric)
For: Classify Mateo three ways and write it into his chart: (1) Veau class with a one-sentence justification, (2) a LAHSHAL string filling the seven positions right-to-left (capitals for complete, a dot for intact, central soft palate clefted), and (3) a shaded striped-Y. Then write one sentence to a surgeon in another city using only your three labels.

How the model answer scores against this rubric
- CompleteProficient: Nothing is left blank: the model fills every part of "Classify Mateo three ways and write it into his chart: (1) Veau class with a one-sentence justification, (2) a LAHSHAL string filling the seven positions right-to-left (capitals for complete, a dot for intact, central soft palate clefted), and (3) a shaded striped-Y. Then write one sentence to a surgeon in another city using only your three labels.".
- 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.
What's next: We can now name Mateo's precisely: , a complete left CL/P. But his is only one shape out of many. Some clefts are on both sides, some stop short of the nostril, and some hide under intact skin. What makes one cleft different from another, and what is the full spectrum of forms? We chase that next time.
