“…Mackool et al 15 analyzed the volume of the medial pterygoid muscle on post-MDO computed tomography scans to demonstrate an average increase of 75% after bilateral mandibular distraction. Others have likewise demonstrated changes in the facial profile related to the anterior displacement of the mandible during MDO with significant increase in distance measured from the tragus to the oral commissure 17 …”

“…Others have likewise demonstrated changes in the facial profile related to the anterior displacement of the mandible during MDO with significant increase in distance measured from the tragus to the oral commissure. 17 The specific benefit of mandibular advancement in the PRS population is the associated anterior displacement of the tongue and resultant increase in airway volume. Our previous work showed that the increase in airway size preferentially affects the retropalatal space, which can lead to supraphysiologic airway dimensions.…”

Introduction:The objectives of this study are to analyze the impact of cleft palate (CP) on upper airway obstruction using polysomnography in patients with Pierre Robin Sequence (PRS) undergoing mandibular distraction osteogenesis (MDO) and subsequent CP repair. Methods: A single-surgeon, retrospective chart review was performed of all patients with nonsyndromic PRS treated with MDO. Severity of upper airway obstruction was evaluated preand post-distraction via polysomnography. Details of MDO and CP repair were collected and any complications recorded.Results: Twenty-one nonsyndromic PRS patients with CP and 6 patients without CP met inclusion criteria. There was no significant difference in predistraction apnea-hypopnea index between the 2 groups (53.4 AE 42.1 versus 34.4 AE 18.9; P ¼ 0.3). Patients with CP had significantly higher predistraction SpO 2 saturation (94.5 AE 1.6% versus 91.0% AE 4.8%; P ¼ 0.01), SpO 2 nadir (74.5% AE 9.1% versus 63.6% AE 11.6%; P ¼ 0.03) and lower percentage time spent below 90% SpO 2 (6.0% AE 7.2% versus 23.6% AE 29.9%; P ¼ 0.04). The rate of oronasal fistulas formation was 38%. The time between MDO and CP repair was shorter for patients with complications (250.8 AE 3.3 versus 370.8 AE 191.9 days; P ¼ 0.08). Five patients experienced relapse of respiratory difficulties after CP repair. Conclusions: The presence of CP in nonsyndromic PRS patients decreases the severity of obstructive sleep apnea by oxygen parameters on PSG. Palatal fistulas and relapse of respiratory distress are common complications of CP repair following MDO. Delaying CP repair may help to decrease complication rates.

“…Since 1992, when McCarthy et al reported the successful treatment of HFM patients with mandibular distraction osteogenesis (MDO), it has become an essential tool in treating HFM ( 3 ). MDO not only effectively lengthens the mandibular ramus but also simultaneously lengthens the affected soft tissues, periosteal muscles, intraosseous vessels, and nerves ( 4 ). However, it is not easy to perform accurately, and the postoperative outcome depends on the precise operation.…”

IntroductionThis study aimed to verify the accuracy and safety of distraction osteogenesis for hemifacial microsomia assisted by a robotic navigation system based on artificial intelligence.MethodsThe small sample early-phase single-arm clinical study, available at http://www.chictr.org.cn/index.aspx, included children aged three years and older diagnosed with unilateral hemifacial microsomia (Pruzansky-Kaban type II). A preoperative design was performed, and an intelligent robotic navigation system assisted in the intraoperative osteotomy. The primary outcome was the accuracy of distraction osteogenesis, including the positional and angular errors of the osteotomy plane and the distractor, by comparing the preoperative design plan with the actual images one week postoperatively. Perioperative indicators, pain scales, satisfaction scales, and complications at one week were also analyzed.ResultsFour cases (mean 6.5 years, 3 type IIa and 1 type IIb deformity) were included. According to the craniofacial images one week after surgery, the osteotomy plane positional error was 1.77 ± 0.12 mm, and the angular error was 8.94 ± 4.13°. The positional error of the distractor was 3.67 ± 0.23 mm, and the angular error was 8.13 ± 2.73°. Postoperative patient satisfaction was high, and no adverse events occurred.DiscussionThe robotic navigation-assisted distraction osteogenesis in hemifacial microsomia is safe, and the operational precision meets clinical requirements. Its clinical application potential is to be further explored and validated.

Presentación de casos clínicos RESUMENCuando los recién nacidos presentan obstrucción de la vía aérea, requieren un manejo urgente y experto para evitar la mortalidad y la morbilidad. La definición de vía aérea difícil se relaciona con problemas en la intubación endotraqueal o en la ventilación a presión positiva con bolsa y máscara o reanimador de pieza en T. El manejo debe basarse en la comprensión del mecanismo fisiopatológico responsable de la vía aérea difícil. Las causas en el recién nacido pueden ser congénitas y/o adquiridas. Se presenta el caso de una recién nacida con síndrome de Treacher-Collins tipo 1 [OMIM #154500] con una disostosis mandibulofacial, micrognatia, hipoplasia malar, paladar hendido, sin cardiopatía congénita, asociado con intubación extremadamente difícil.
