The incidence of abnormal fontanel differs, depending on the abnormality and cause. 6. How? The incidence of deformational plagiocephaly is approximately one in 300 live births compared with the incidence of the rarer lambdoid synostosis, which is approximately three in 100,000 live births.16,17 The number of infants with deformational plagiocephaly has increased, partly as a result of the back to sleep campaign to prevent sudden infant death syndrome and also because of the increased awareness of deformational plagiocephaly among primary care physicians.18,19.

Associated findings include decreased muscle tone, seizures, decreased hematocrit, vomiting, and alterations in consciousness.20, Tumors also should be considered in the differential diagnosis of a bulging fontanel. Scalp edema (caput succedaneum) is a very common finding. The ipsilateral ear in lambdoid synostosis is displaced posteriorly toward the fused suture compared with the anterior displacement that occurs in infants with deformational plagiocephaly. Neonates are very sensitive to external stimuli during the first week of life. JOSEPH KIESLER, M.D., AND RICK RICER, M.D. He had an open, flat fontanelle without overriding sutures. In addition to craniofacial malformations, syndromic craniosynostosis involves multiple systems (i.e., cardiac, genitourinary, musculoskeletal). A single copy of these materials may be reprinted for noncommercial personal use only. However, referral is appropriate at any age.

In the photo above, the lingual frenulum under the tongue is restricting tongue elevation when the baby cries. The major sutures of the skull include the following: Metopic suture. Because dramatic changes have occurred in the field, particularly in molecular biology, this new edition has been rewritten and new chapters have been added on the growth of sutures, craniofacial surgery, and epidemiology and clinical . We . This content does not have an English version. The diagnosis of deformational plagiocephaly can be made clinically by viewing the infants head from the top (vertex view).
