They also found a tendency to larger values for measurements running away from the coronal and closer to the sagittal sutures, with the thickest points located simultaneously close to the
lambdoid and sagittal sutures--7.169 mm and 7.081 mm, on the right and left parietal, respectively.

lambdoid craniosynostosis (right) (https://www.cincinnatichildrens.org/health/c/craniosynostosis/).
After reflecting the scalp, coronal, sagittal,
lambdoid sutures were studied applying Acsadi-Nemeskeri scale endocranially, after removing the calvaria by craniotome taking due care to include complete coronal and sagittal suture.
1977 The Effect of Artificial Cranial Deformation on the Incidence of Wormian Bones in the
Lambdoid Suture.
Asterion is the meeting point of the
lambdoid, occipitomastoid, and parietomastoid sutures or the point where the temporal, parietal, and occipital bones meet.
Classification of craniosynostosis Non-syndromic Suture involved Simple Scaphocephaly Sagittal Anterior plagiocephaly Unilateral coronal Posterior plagiocephaly Unilateral
lambdoid Trigonocephaly Metopic Compound Variable More than 1 suture Brachycephaly Bilateral
lambdoid Turribrachycephaly Bilateral coronal Syndromic Crouzon's syndrome Typically bilateral coronal Apert's syndrome Usually coronal, often
lambdoid Pfeiffer syndrome Multiple suture involvement Other, e.g.
Encephaloceles are classified as occipital when found at or posterior to the
lambdoid suture, parietal when found between the
lambdoid and the coronal suture and anterior when they occur anterior to the coronal suture.
Microcephaly had resulted from early closure of sagittal and coronal sutures and
lambdoid suture while plagiocephaly resulted from early metopic suture closure.
Shprintzen-Goldberg syndrome (SGS) is characterized by craniosynostosis (involving the coronal, sagittal, or
lambdoid sutures), distinctive craniofacial features, skeletal changes (dolichostenomelia, arachnodactyly, camptodactyly, pes planus, pectus excavatum or carinatum, scoliosis, joint hypermobility, or contractures), neurologic abnormalities, mild-to-moderate intellectual disability, and brain anomalies.
Supraorbital nerve is the larger terminal branch of the frontal nerve, which is a branch of ophthalmic division of trigeminal nerve and it traverses through the SON/SOF and divides into medial and lateral branches to supply the palpebral filaments to the upper eyelid, conjunctiva and skin of the scalp as far back as the
lambdoid suture.
Lambdoid craniosynostosis, which is caused by early fusion of the
lambdoid suture, is rare but it is "what people worry about with posterior flattening," Dr.
1) with temporal lobe herniation into the orbit (buphthalmos), calvarial defects (
lambdoid and, uncommonly, coronal suture) (Fig.2a-d), and dural ectasia.
