Background: The following study is carried out, whose objective is to quantitatively determine the anthropometric changes of hard and soft tissues through skeletal, facial, and airway measurements in pediatric patients diagnosed with Sequence of Pierre Robin treated by Bilateral Osteogenic Distraction. Methods: A descriptive and comparative study was carried out, performing a retrospective analysis of longitudinal design, defining a representative sample of 8 patients (5 male and 3 female), who attended the Oral and Maxillofacial Surgery service “Dr. Atilio Perdomo” from the “Dr. Ángel Larralde” located in the state of Carabobo, Venezuela, during the period 2015-2022 diagnosed with Pierre Robin Sequence that presented clinical characteristics micrognathia, glossoptosis and signs of upper airway obstruction. Results: To collect the necessary information, several methods were used, such as reviewing the clinical history of the patient under study, performing a facial and intraoral clinical examination, and analyzing conventional radiographs such as orthopantomography, lateral cephalic radiography, and anterior-posterior skull radiography. Thilander, McNamara, and Bjork Jarabak tracings were also used, as well as Cone Beam CT scans and facial photographs. The Jarabak and Thilander tracings showed an improvement in mandibular body length and a more pronounced mentolabial groove. Additionally, an increase in facial height was observed. Despite this, growth was maintained with a brachiocephalic and horizontal pattern in relation to mandibular growth. On the other hand, McNamara's layout showed a favorable evolution in the airway, by measuring the upper and lower pharynx points, as well as the increase in the lower third. These findings were similar to those found in the Jarabak layout.
