The word "sequence" suggests that one anomaly leads to subsequent abnormalities, and micrognathia is considered to be the inciting anomaly in patients with PRS.
During the physical examination, we observed facial asymmetry, the presence of bilateral ear pits, hooded eyelids, myopia, micrognathia and upward slanting of palpebral fissures (Fig.
He presented micrognathia, multiple contractures of the joints (arthrogryposis), rocker bottom feet, clenched hands and scissor legs.
She had a flat occiput, high forehead, capillary haemangiomas (forehead), hypertelorism, upward slanting palpebral fissure, bilateral epicanthic folds, posteriorly angulated ears, small nose and mouth, long philtrum, full cheeks, micrognathia, short and broad neck, widely spaced nipples and severe hypotonia (Figure 1a).
[16] In addition, patients who had micrognathia, retrognathia, macroglossia, adenotonsillar hypertrophy, hypothyroidism, mandibular hypoplasia, occlusion disorders, high blood pressure, BMI [greater than or equal to]30, neck circumference [greater than or equal to]40 cm, and smoked cigarettes and/or used drugs other than Vitamin D were excluded from the study.
PRS is a congenital condition characterized by micrognathia, glossoptosis, cleft palate, and laryngeal anomalies (1), and it causes feeding problems and respiratory complications.
Cerebro-costo-mandibular syndrome (CCMS) is characterized by severe micrognathia with glossoptosis, short and cleft soft palate, bell-shaped small thorax with gaps between the posterior ossified rib and anterior cartilaginous rib and postnatal growth and mental deficiency (1, 2).
The patients might have subtle facial features including triangular faces, micrognathia, and exophthalmos.
If left untreated, it can result in neck webbing and contractures (as in the case of the 14-year-old girl in our study) and mandibular deformities, such as micrognathia and exostosis-like protuberances [18].
Patients typically show a distinct physiognomy, initially also described as craniocarpotarsal dysplasia [1, 4]: contractures of musculature and soft tissues lead to characteristic circumoral fibrosis, microstomia, pursed lips, micrognathia, and a short webbed neck with severely limited range of motion.
Dysmorphism included unilateral ptosis, deep-set eyes, low set ears, CP, and micrognathia (Figure 1(a)).
