Does Mandibular Distraction Osteogenesis for Robin Sequence Create Altered Craniofacial Morphology and Disrupt Tooth Development?

Background: Robin Sequence (RS) infant patients may require mandibular distraction osteogenesis (MDO) to improve airway. The distracted mandible may grow vertically and the developing dentition may be disrupted.

Purpose: The study purpose was to measure the association of MDO on craniofacial morphology and tooth development in RS subjects.

Does surgical sequencing influence the accuracy of maxillary positioning in bimaxillary cleft orthognathic surgery?

Purpose: To evaluate whether the sequence of osteotomies influences the accuracy of maxillary positioning in patients with cleft palate ± cleft lip undergoing bimaxillary orthognathic surgery (OGS).

Methods: This was a prospective study of patients with Veau 2-4 clefts who underwent bimaxillary OGS at tertiary-care children's hospital over a 3-year period. The primary predictor variable was the sequence of osteotomies (maxilla-first versus mandible-first).

Conceptual Principles in Pediatric Craniomaxillofacial Reconstruction.

Pediatric craniomaxillofacial reconstruction must be approached through the lens of growth and durability. A systematic approach of matching defects to donor tissue drives the selection of autologous reconstructive technique. The menu of available methods for reconstruction can be organized in a manner similar to adults, with special considerations for growth and development.

Head and Neck Vascular Anomalies in Children.

Craniomaxillofacial vascular anomalies encompass a diverse and complex set of pathologies that may have a profound impact on pediatric patients. They are subdivided into vascular tumors and vascular malformations depending on biological properties, clinical course, and distribution patterns. Given the complexity and potential for leading to significant functional morbidity and esthetic concerns, a multidisciplinary approach is generally necessary to optimize patient outcomes.

Eyeing Risks: A Critical Analysis of the Use of Periorbital Steroids in Fronto-orbital Advancement.

Objective: To evaluate the outcomes associated with two techniques of periorbital steroid administration in bilateral fronto-orbital advancement (FOA).

Design: Multi-institutional retrospective chart review.

Setting: Two high volume, tertiary US craniofacial centers.

Retrospective Cohort Studies in Craniofacial Outcomes Research: An Epidemiologist's Approach to Mitigating Bias.

Retrospective cohort studies, defined as a follow-up study in which outcome occurred prior to study onset, are common in craniofacial outcomes research and will continue to be prevalent given the increasing availability of secondary datasets and inherent prospective study limitations. However, if available data are not adequately measured, or necessary variables are absent, retrospective cohort studies can be particularly prone to bias. This brief communication aims to highlight the primary sources of bias, including measurement error, selection bias, and confounding.

Gender-Affirming Facial Surgery: Lower Third of the Face.

This article is intended to give the reader an overview of facial gender-affirming procedures applicable to the lower face and neck. A review of facial analysis in the context of masculine versus feminine facial features and the contributions of both soft tissue and bone to this anatomy is provided. The use of systematic facial evaluation and patient-driven concerns as a guide for presurgical planning is reviewed.

Current Trends in Orthognathic Surgery.

Orthognathic surgery has evolved significantly over the past century. Osteotomies of the midface and mandible are contemporaneously used to perform independent or coordinated movements to address functional and aesthetic problems. Specific advances in the past twenty years include increasing fidelity with computer-assisted planning, the use of patient-specific fixation, expanding indications for management of upper airway obstruction, and shifts in orthodontic-surgical paradigms.

Preoperative Imaging and Surgical Findings in Pediatric Frontonasal Dermoids.

Objective: To review cases of congenital frontonasal dermoids to gain insight into the accuracy of preoperative computed tomography (CT) and magnetic resonance imaging (MRI) in predicting intracranial extension.

Methods: This retrospective study included all patients who underwent primary excision of frontonasal dermoids at an academic children's hospital over a 23-year period. Preoperative presentation, imaging, and operative findings were reviewed.

Perioperative complications and secondary retethering after pediatric tethered cord release surgery.

Objective: Tethered cord syndrome refers to a constellation of symptoms characterized by neurological, musculoskeletal, and urinary symptoms, caused by traction on the spinal cord, which can be secondary to various etiologies. Surgical management of simple tethered cord etiologies (e.g.

Does the Low and Short Medial Cut Affect Lingual Nerve Recovery after Sagittal Split Osteotomy?

Background: The purpose of this study was to evaluate the recovery of lingual nerve (LN) neurosensory function in patients undergoing sagittal split osteotomy (SSO) with a low and short medial horizontal cut.

Methods: This was a prospective study of patients with mandibular deformities undergoing SSO with a low and short medial horizontal cut over a 4-year period. The outcomes of interest were neurosensory recovery of the LN, as assessed objectively using functional sensory recovery (FSR) and subjectively by patient report.
