The blade is advanced and its tip is made to pass posterior to the epiglottis. In this technique, 1 a straight blade laryngoscope is introduced from the right corner of the mouth along the groove between the tongue and the tonsil, using leftward and anterior pressure to displace the tongue to the left of the laryngoscope. Prenat Diagn 1999 19:567-569.Editor-The right molar approach for laryngoscopy has been described for intubation of patients with a difficult airway as the paraglossal 1 and retromolar 2 technique, respectively.

Williams et al (1981) found that 74% of RS cases.Specific recognized syndrome, and only 40% had isolated RS. Hanson and Smith (1975) found that 25% of RSĬases had specific syndromes, another 35% had multiple anomalies without a.The proportion of cases that are isolated varies in different studies. The most severe cases of micrognathia are unlikely to be isolated RS caused by Some deformational cases of RS have been associated with oligohydramnios. Isolated RS is often a deformation resulting from intra-uterine forcesĪcting on the mandible, which restrict its growth and impact the tongue between A major distinction should be madeīetween isolated occurrences of Robin sequence and cases in which RS is part ofĪ recognized syndrome, or part of a complex of multiple anomalies or an Malformations and deformations, and connective tissue dysplasia Heterogeneity and phenotypic variability. Robin sequence (RS) is etiologically heterogenous.Įtiologic heterogeneity suggests pathogenetic Most cases are sporadic, however there are reported familial Pierre Robin syndrome is classified as a first branchialĪrch syndrome (1). Larger than normal, but because of the small mandible, it is large for theĪirway and causes obstruction.
