Blepharophimosis |
"A fixed reduction in the vertical distance between the upper and lower eyelids with short palpebral fissures." [PMID:19125427] |
When the palpebral fissures are severely shortened, they cannot be widely separated, actively or passively. Blepharophimosis is an acknowledged bundled term (short vertical and horizontal distance). When palpebral fissures are severely shortened, they cannot be widely separated, actively or passively. Ptosis is the term to be used when the reduction in eyelid opening is not fixed but can be increased actively or passively. Blepharophimosis is often associated with Epicanthus inversus. |

Optic disc pallor |
"A pale yellow discoloration of the optic disk (the area of the optic nerve head in the retina). The optic disc normally has a pinkish hue with a central yellowish depression." [HPO:probinson] |
Optic disc pallor can be judged clinically with serial color photographs or by comparison to the other eye. The pallor reflects replacement of dead axons by glial tissue. The loss of the small capillaries within the nerve accounts for the shift from orange-pink to white. |

Bell-shaped thorax |
"The rib cage has the shape of a wide mouthed bell. That is, the superior portion of the rib cage is constricted, followed by a convex region, and the inferior portion of the rib cage expands again to have a large diameter." [HPO:probinson] |
A bell-shaped thorax is a non-specific finding. In newborns, bell-spahed thorax can indicate a history of intrauterine neuromuscular abnormalities. |

Microcephaly |
"Head circumference below 2 standard deviations below the mean for age and gender." [PMID:15806441, PMID:19125436, PMID:25465325, PMID:9683597] |
Head circumference is measured from just above the glabella (the most prominent point on the frontal bone above the root of the nose) to the most posterior prominent point of the occipital bone using a tape measure. Some standard charts are organized by centiles, others by standard deviations. It is important to add an indication of how far below the normal standard the head circumference is if an accurate assessment of this can be made. Microcephaly is an absolute term. The term relative microcephaly can be used when the head size centile is less than the centile for height, for example, head size at the 3rd centile with height at the 75% for age and sex. On prenatal ultrasound, microcephaly is diagnosed if the head circumference or the biparietal diameter is more than three standard deviations below the mean. Microcephaly is divided into primary microcephaly, which is present at birth, and secondary microcephaly, which develops postnatally. The crucial difference between these groupings is that primary microcephaly is usually a static developmental anomaly, whereas secondary microcephaly indicates a progressive neurodegenerative condition |

Diastema |
"Increased space between two adjacent teeth in the same dental arch." [PMID:19125428] |
Usually there is contact between the lateral aspects of the permanent teeth, at their broadest point. Diastema can apply to any pair of teeth and the term should be modified by a descriptor of the involved teeth. This descriptor must be distinguished from Widely spaced teeth. |

Depressed nasal bridge |
"Posterior positioning of the nasal root in relation to the overall facial profile for age." [PMID:19152422] |
The adjective "depressed" here does not indicate an active process but a status. A depressed nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed independently. In infancy, the nasal bridge is relatively more posterior than in the older person. The term depressed nasal bridge should only be used when the bridge is more posterior than is typical for age and ethnic background. |

Brachycephaly |
"An abnormality of skull shape characterized by a decreased anterior-posterior diameter. That is, a cephalic index greater than 81%. Alternatively, an apparently shortened anteroposterior dimension (length) of the head compared to width." [HPO:probinson, PMID:19125436] |
Cephalic index is the ratio of head width expressed as a percentage of head length. The normal range is 76-80.9%. Head length is measured between the glabella (the most prominent point on the frontal bone above the root of the nose) and the most prominent part of the occiput in the midline, using spreading calipers. Head width is measured between the most lateral points of the parietal bones on each side of the head, using spreading calipers. Cephalic index standards are derived from Caucasians and have limited relevance for other races and ethnicities. Current norms also have limited validity because of changes in infant sleeping position and consequent changes in head shape. New data should be developed. Brachycephaly is distinct from Flat occiput, but both can be present in the same individual and should be coded separately. |

The width of the mouth varies with facial movement and must be assessed when the subject has a relaxed (neutral) face. This term replaces microstomia, small oral aperture, and small mouth because the reduced opening of the mouth is secondary to reduced width. |

High palate |
"Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective)." [PMID:19125428] |
The measuring device for this assessment is described in (Hall JG, Froster-Iskenius UG, Allanson JE, Gripp K, Slavotinek A. 2006. Handbook of Normal Physical Measurements. 2nd edition. Oxford Medical, publishers). A high palate is often associated with a narrow palate. However, a narrow palate can easily give a false appearance of a high palate. Height and width of the palate should be assessed and coded separately. We do not recommend the subjective determination because this term can be overused and\napplied inaccurately. |

Narrow palm |
"For children from birth to 4 years of age, the palm width is more than 2 SD below the mean; for children from 4 to 16 years of age the palm width is below the 5th centile; or, the width of the palm appears disproportionately narrow for its length." [PMID:19125433] |
Palm width is measured across the palm at the level of the MCPJ (radial aspect of the F2 MCPJ to the ulnar aspect of the F5 MCPJ). Norms are specified in [Hall et al., 2007]. Caution is advised for the subjective assessment as the breadth may be in the normal range with disproportionately increased length, which appears narrow. This finding may be associated with elongated/slender limbs in general, but that finding does not bear on the coding of this feature. Proximal narrowing may indicate small thenar or hypothenar eminences. This term replaces "narrow hands" as that term may leave the impression that it includes the thumb, which it does not. |
