Abstract The differential diagnostics between the common positional posterior plagiocephaly and relatively rare lambdoid synostosis is important due to the differences in their treatment plan and clinical management. Positional plagiocephaly and lambdoid synostosis both present with occipital flattening. The incidence of deformational plagiocephaly is approximately one in 300 live births compared with the incidence of the rarer lambdoid synostosis, which is … Occipital plagiocephaly is the creep and the asymmetry of the posterior part of the head (parietal part). 2000 Jul;53(5):367-77. Most cases of occipital plagiocephaly are due to the external pressure on the skull (endometrial or after birth), while a small percentage is due to premature closure (synostosis) of the lambdoid suture. The optimal treatment is prevention through active counterpositioning of sleeping babies until they are able to move their heads freely during sleep, usually by six months of age. The occiput is flat on the affected It can be caused by lambdoid synostosis, which is an extremely rare condition. Deformational plagiocephaly, unilateral coronal craniosynostosis, and lambdoid craniosynostosis all cause oblique deformities of the skull. This condition is generally treated with cranial vault expansion surgery. Lambdoid suture synostosis is the least common type of single suture synostosis. Positional plagiocephaly is a fairly common and treatable condition. FIGURE 2 Right lambdoid synostosis. Lambdoid synostosis (posterior plagiocephaly) This rare form of craniosynostosis can be mistaken for its very common deformational equivalent. Lambdoid synostosis produces prominence above the mastoid bone and frequently a palpable ridge over the suture-features that are usually absent in positional plagiocephaly. The features of true lambdoid synostosis versus those of deformational plagiocephaly secondary to positional molding are inadequately described in the literature and poorly understood. They are separate entities with different etiologies resulting in clear differences of physical examination, radiologic findings, and clinical course. o Lambdoid synostosis is least common18; mistaken for plagiocephaly. However, the two causes of posterior plagiocephaly have different clinic features. RESULTS: In all 8 cases of unilateral LS and 258 cases of positional plagiocephaly, the diagnosis was established by clinical examination alone. Lambdoid Synostosis Versus Positional Posterior Plagiocephaly, a Comparison of Skull Base and Shape of Calvarium Using Computed Tomography Imaging. Positional Plagiocephaly • Treatment Options – Repositioning – Physical Therapy Unlike craniosynostosis, the skull plates are not fused, but moulded into a different shape – a condition that does not require surgical treatment. Positional plagiocephaly is a common diagnosis. Positional plagiocephaly can often be treated by repositioning your baby’s head when they’re laying down. A Clinician’s guide to positional plagiocephaly 3 Differential Diagnosis Positional plagiocephaly should be differentiated from four other conditions which result in plagiocephaly: congenital muscular torticollis (CMT), positional torticollis, unilateral lambdoid synostosis and unilateral coronal synostosis. What are the signs and symptoms of Pediatric Lambdoid Synostosis? This has resulted in many infants in several craniofacial centers across the United States undergoing major intracranial procedures for non-synostotic plagiocephaly. The fused lambdoid suture has a palpable ridge, and there is an ipsilateral occipitomastoid bulge. History of a preferred sleeping position is noted in deformational plagiocephaly. Lambdoid craniosynostosis may be confused with positional or deformational plagiocephaly – a disorder that affects the skull, making the back or side of a baby’s head appear flattened. This is called positional plagiocephaly, or “flat head syndrome.” Similiar to craniosynostosis, plagiocephaly can cause flat spots and bulging areas on the head and forehead, but it is not craniosynostosis. Occipital plagiocephaly is a type of plagiocephaly.It is used to describe the shape of the skull which is a result of an early fusion of the lambdoid suture.The premature fusion may occur either on one side or both sides of the suture. Lambdoid synostosis is present at birth; whereas, deformational plagiocephaly usually occurs some weeks after birth. Br J Plast Surg. J Craniofac Surg. Management of Positional Plagiocephaly by Allied Health Professionals SummaryA clinical Guideline to support best practice for assessment referral and management of infants with positional plagiocephaly. The differential diagnostics between the common positional posterior plagiocephaly and relatively rare lambdoid synostosis is important due to the differences in their treatment plan and clinical management. Positional (or deformational) plagiocephaly is when a baby's head has a flat spot or is misshapen due to repeated pressure to the same area of the head. The surgical indication in posterior plagiocephaly has been and still is a subject of discussion. Unlike other types of craniosynostosis, this particular type of cranial deformity does not show the typical radiological findings that are encountered in cases of prematurely fused cranial sutures. • Suspicion of craniosynostosis requires referral back to pediatrician for evaluation by a pediatric neurosurgeon or craniofacial physician.10 • Most infants require surgical intervention to open prematurely closed sutures. Also known as: deformational plagiocephaly Occipital plagiocephaly . Stephanie Gurevich, PA-C. Jessica Wisniewski, MSN, CPNP. From the vertex view, a patient with lambdoid synostosis has a trapezoid shaped head. Lambdoid synostosis or occipital plagiocephaly is characterized by a trapezoid shape to the head when viewed from above, tilted skull base (ipsilateral side displaced inferiorly), and ipsilateral ear displaced inferiorly and posteriorly. In a few very rare cases one of the lambdoid sutures closes prematurely. It can be easily confused with positional plagiocephaly which is caused by the baby sleeping preferentially to … Plast Reconstr Surg 98:765-776, 1996. Occipital plagiocephaly: unilateral lambdoid synostosis versus positional plagiocephaly. Concerns that a flat head may be synostosis rather than positional trigger several referrals to the craniofacial unit. plagiocephaly proper is generally reserved for the deformation of the skull seen in either coronal (anterior plagiocephaly) or lambdoid (posterior plagiocephaly) synostosis, or else in deformational plagiocephaly. (Left) Positional molding produces a head shaped like a parallelogram. A) An Treatment for each condition is markedly different. Occipital plagiocephaly: unilateral lambdoid synostosis versus positional plagiocephaly archives of disease in childhood pdf part 1 the suture: normal development and pathology semantic scholar thieme: pediatric neurosurgery: tricks trade (PMID: 8823012) [4] David DJ, Menard RM. 2015 Sep;26(6):1917-22. doi: 10.1097/SCS.0000000000002098. Patients with lambdoid suture craniosynostosis have flatness of the back of the head and a downward bulging of the skull behind the ear on the side of the closed suture. The differential diagnosis of posterior plagiocephaly: true lambdoid synostosis versus positional molding. ... Distinguishing Between Lambdoid Craniosynostosis and Deformational Plagiocephaly: A Review of This Paradigm Shift in Clinical Decision-Making and Lesson for the Future - Craig B. Birgfeld, Carrie Heike, 2020 In positional plagiocephaly (LEFT) there is shifting of the skull base, but no restriction of growth on one side versus the other. 4 These primary changes in the posterior cranial vault may produce a canting of the entire craniofacial complex, better seen from the front. 1996 Oct;98(5):765-74; discussion 775-6. Treatment for Flat Head. It can either involve single or asymmetric multiple sutures. Therefore, a detailed examination of … Vertex view. In positional plagiocephaly however, the cranial sutures have not closed early. From Huang MHS, Gruss JS, Clarren SK, et al: The differential diagnosis of posterior plagiocephaly: True lambdoid synostosis versus positional molding. Treatment for Positional Plagiocephaly Treatment for Positional Plagiocephaly is based on the age of the infant and the severity of the deformity. sagittal, metopic, coronal, and lambdoid. Children with lambdoid synostosis may be misdiagnosed as having positional plagiocephaly, since the two conditions appear similar externally. Plagiocephaly refers to a type of craniosynostosis in which there is asymmetric premature closure of the coronal and/or lambdoid sutures. Premature coronal suture closure is associated with the Harlequin eye deformity. Note the flatness on the back-right side with bossing (protrusion) on the back left. Lambdoid Synostosis And Occipital Plagiocephaly Clinical Decision Rules For Surgical. Premature closure leads to flattening of the back of the head on the affected side and is known as plagiocephaly. 15,27 Misdiagnosis is common and the condition may be confused with lambdoid synostosis. Craniosynostosis and Positional Plagiocephaly . Depiction of the typical characteristics of lambdoid synostosis. Hurmerinta K, Kiukkonen A, Hukki J, Saarikko A, Leikola J. Hurmerinta K, et al. Posterior plagiocephaly due to lambdoid suture synostosis is a rare event today, with the majority of observed posterior plagiocephaly secondary to positional molding. The right ear is displaced posteriorly (backwards). Occipital plagiocephaly. (Right) Unilateral lambdoid synostosis produces a trapezoidally shaped head.
