5 bundles · 9 layers · 13 findings · 22 questions
Phenotype and terminology Establish what oxycephaly denotes in the record being interpreted.
Pointed vault definition
Anchor recognition in the recorded cranial contour.
Defining contour evidence
Record whether the vault is described or demonstrated as conical or pointed, retaining the observer and evidence.
- What observed feature supports calling this cranial vault pointed or conical? definition
- Which examination, image or report documents that feature, and at what age? provenance
Overlapping cranial labels
Handle acrocephaly and turricephaly without imposing universal synonymy.
Source-specific term mapping
Preserve each source's definition and distinguish an explicit equivalence from an inferred mapping.
- Does this source use oxycephaly interchangeably with acrocephaly or turricephaly, or distinguish them? definition
- Would a tall but rounded vault meet this source's criteria? boundary
Cranial form and course Describe pointedness, proportions and their development over time.
Contour and proportions
Separate visible apex configuration from cranial dimensions and head size.
Reproducible shape description
Retain views, landmarks and measurement methods so observations can be compared.
- Which views and landmarks demonstrate the location and extent of the pointed contour? measurement
- Do the recorded dimensions describe cranial height, breadth, length or circumference, and which reference was used? measurement
Developmental and treatment course
Locate shape observations within growth and intervention history.
Dated contour trajectory
Distinguish first recognition, subsequent progression and treatment-related changes.
- When was the pointed contour first documented, and what earlier observations are available? provenance
- Were changes observed during growth or after a cranial procedure, using comparable methods? measurement
Suture and diagnostic context Connect the phenotype to independently documented anatomical and diagnostic findings.
Suture evidence
Record the assessed state of each relevant cranial suture.
Fusion pattern confidence
Retain named sutures, laterality where applicable, assessment method and uncertainty.
- Which sutures were assessed, and what evidence supports the reported state of each? provenance
- Is craniosynostosis documented independently, or merely inferred from the oxycephaly label? boundary
Isolated or associated presentation
Represent diagnostic context without expanding this entry into a syndrome model.
Associated diagnosis status
Link relevant assessments and distinguish confirmed diagnoses from differentials or incomplete evaluation.
- What associated findings prompted a syndromic assessment, and what conclusion was documented? provenance
- Does 'isolated' reflect a completed assessment or only the absence of additional information? boundary
Functional state and clinical action Keep appearance, functional findings and clinician-directed actions separately traceable.
Functional evidence
Link relevant pressure, visual and developmental assessments when documented.
Documented functional concerns
Represent each concern with its assessment date, evidence and attribution status; missing assessment is not a normal result.
- What pressure-related, ophthalmic or developmental concerns have actually been assessed, and with what results? provenance
- Which findings are clinically attributed to the cranial condition, and which remain unexplained or independently diagnosed? boundary
Review and follow-up
Translate the documented assessment into bounded information-handling and follow-up actions.
Evidence-linked next action
Record the responsible clinician's plan, outstanding evidence and specified reassessment criteria.
- What specialist review or follow-up has been recommended, by whom, and for which documented finding? action
- What missing evidence prevents a firmer classification or management decision? action
- What changes does the existing clinical plan identify as requiring earlier reassessment? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
Oxycephaly is a cranial deformity characterized by an abnormally high, pointed skull, typically associated with premature fusion of multiple cranial sutures.
In scope
- Pointed or conical configuration of the cranial vault
- Source-specific meanings of oxycephaly and overlapping terminology
- Evidence connecting the observed shape to cranial suture abnormalities
- Age, growth history and changes following cranial intervention
- Links to associated diagnoses, functional assessments and clinical decisions
Out of scope
- The complete classification and management of craniosynostosis
- Full models of syndromes in which oxycephaly occurs
- General head-size disorders without the defining shape
- Detailed operative techniques for cranial reconstruction
- Independent diagnosis and treatment of neurological or ophthalmic disorders
Why it exists Filled
Enable an agent to recognise and document oxycephaly, distinguish skull-shape observations from causal diagnoses, and identify what evidence is needed for clinical assessment.
Distinguishing features Filled
- Require documentation of a pointed or conical cranial contour; the HPO-derived definition describes this shape. [NCBI MedGen: Oxycephaly](https://www.ncbi.nlm.nih.gov/medgen/1634950)
- Distinguish pointedness from increased cranial height alone, while recording terminology overlap: MedGen lists overlapping synonyms under turricephaly. [NCBI MedGen: Turricephaly](https://www.ncbi.nlm.nih.gov/medgen/1726910)
- Record suture findings separately: a shape label alone must not be converted into a confirmed pattern of premature suture fusion.
- Distinguish the cranial phenotype from a syndrome diagnosis; co-occurring findings require their own evidence.
- Separate current appearance from historical appearance when growth or cranial surgery has altered the contour.
What robots and AI may and may not do Filled
Must not
- Diagnose craniosynostosis from a photo of a child.
- Mock or comment on a person's head shape.
- Recommend helmets, surgery or other treatment for a specific child.
- Share images of a child's head without parental consent.
Only with a human decision
- Surgical decisions on the skull.
May
- Explain the skull shape and its causes in general terms from reputable medical sources.
- Suggest that parents worried about a baby's head shape see a paediatrician.
Moral aspects Filled
- Visible skull differences expose children to staring and bullying.
- Historical skull measurement was used to justify racism; head shape must not be read as a sign of character or worth.
Who is affected
- Affected children and adults
- Parents
- Siblings
Owners Filled

Capabilities and actions required Filled
- Classify an observation as compatible, incompatible or insufficiently documented for the stated definition of oxycephaly.
- Compare source terminology while retaining original labels and unresolved synonym mappings.
- Assemble a dated cranial-shape and growth history from examinations and existing reports.

Context of use required Filled
- Oxycephaly is encountered in clinical assessment and documentation of an unusually high, pointed skull.
- The term helps describe cranial shape in craniofacial and neurosurgical settings, while the underlying suture abnormalities require separate assessment.
Sources Filled

Open questions
- Should the registry adopt the morphological phenotype meaning of oxycephaly, a narrower craniosynostosis-associated meaning, or explicitly support both?
- Which authoritative terminology mappings distinguish oxycephaly from acrocephaly and turricephaly, and how should conflicting mappings be represented?
- Are there validated, age-specific criteria for cranial pointedness that improve agreement beyond qualitative assessment?
- Under narrower clinical definitions, which suture patterns and developmental courses are required rather than merely associated?
- Which evidence-based assessment and follow-up criteria apply specifically to oxycephaly rather than being inherited from a broader craniosynostosis diagnosis?
