Book Description
Mandibular distraction osteogenesis (MDO) is a treatment option for infants with Robin Sequence (RS) who have severe upper airway obstruction. While this procedure is successful in eliminating airway distress, it can cause changes in craniofacial morphology and tooth development in the growing patient. This study examines the effect of mandibular distraction osteogenesis on craniofacial morphology and tooth development in patients with RS at pre-operative, intra-operative, and mixed dentition timepoints as compared to patients without craniofacial conditions and to patients with RS not treated with MDO. Fourteen infant patients with RS undergoing MDO from Seattle Children’s Hospital met the study inclusion criteria. Pre-operatively at T1, the MDO treatment group was compared to 37 infants without craniofacial conditions. Following MDO at T2, intra-operative and post-operative data was collected from the MDO treatment group. At the mixed dentition follow-up (T3), the MDO treatment group (13 patients) was compared to 19 patients with RS who did not undergo MDO. Data from both groups of patients with RS was compared to norms established by the Michigan Growth Sample. Selected cephalometric linear and angular measurements were assessed at each timepoint and tooth development was evaluated from a panoramic radiograph using a tooth assessment grading scale. Before surgery, the patients with RS planned for MDO had significantly more obtuse gonial angles and shorter mandibular body lengths. Changes occurring secondary to MDO in patients with RS were increased mandibular body length, a less obtuse gonial angle, and forward rotation of the mandible. At the mixed dentition timepoint, patients with RS who had MDO had a significantly more obtuse gonial angles (152.5o, p= 0.006) and steeper mandibular plane angles (51.9o, p= 0.0033) than patients with RS who did not have MDO. The RS-affected groups more similarly resembled one another as compared to the normal control, and they demonstrated significant measures of vertical growth. In the mixed dentition, 30% of RS with MDO patients had one or more teeth with abnormal development as compared to no tooth abnormalities in patients with RS without MDO (p= 0.020). There was no difference in frequency of missing teeth between the groups. There was a low rate of complications associated with MDO in this study, and all patients completed the prescribed course of distraction. No patient with RS required tracheostomy between birth and the time of evaluation in the mixed dentition.

Abstract: Background Distraction osteogenesis (DO) was first applied on the human craniofacial skeleton in 1992 by McCarthy et al.1 who performed lengthening of the mandible in patients with hemifacial microsomia and Nager's syndrome. Further advances in this field have since then led to the widespread use of this modality for the treatment of numerous congenital and acquired craniofacial skeletal anomalies. In 2001, a review by Swennen et al2 concluded that up to year 1999, this form of treatment was gaining intense popularity but that the main drawbacks included insufficient data on long term results and relapse. A systematic review of the last decade on functional outcomes and long term complications following distraction osteogenesis of the facial skeleton is presented. Methods A structured systematic literature search, with predefined inclusion and exclusion criteria from relevant computer databases and journals were performed. The journals were evaluated and critically appraised by 2 reviewers separately in 3 rounds. Papers were categorized according to the level of evidence, the quality of methodology and the specific field of functional outcomes and long term complications. Results were then categorized according to the type of distraction movements, ie maxillary advancement and mandibular lengthening. Results A total of 42 papers comprising of 16 studies for maxillary advancement and 26 studies for mandibular lengthening were included in this review. Maxillary advancement was found to be beneficial in patients with cleft maxillary hypoplasia in terms of achieving aesthetic outcome but the risk for velopharyngeal insufficiency remains uncertain. The achieved maxillary advancement was stable if performed on adult patients while a recurrence of midface retrusion was noted if DO was performed on growing patients. Overcorrection was recommended in these cases to an estimated value of 20-50%. Mandibular lengthening was 99% successful in relieving respiratory obstruction in patients with isolated Pierre Robin Sequence (PRS) or syndromic micrognathic infants preventing the need for tracheostomy in the long term, and in 89% successfully decannulating infants with pre-existing tracheostomy. However, feeding and growth outcomes after airway obstruction was relieved remain unknown due to lack of sufficient evidence. Unilateral mandibular DO was successful in achieving aesthetic symmetrical facial balance in patients with hemifacial microsomia however a total loss of corrected distraction length was noted by the end of growth period if DO was performed during growth. Conclusions DO achieved stable results in terms of lengthening the maxilla and mandible but was also noted to cause restricted growth potential of the distracted bone. Hence, the benefits of performing DO during active growth should be weighed against the likely need for a second surgery due to a growth deficit of distracted bone and future surrounding bone growth. However DO in adults remains an alternative to conventional orthognathic surgery and choice of treatment should be patient centred.

Book Description
Cleft lip and palate represents the most common congenital facial anomaly. Congenital anomalies are one of the top 10 causes of disability and suffering in many low and middle income countries (LMICs.) Further, an estimated 30% of the global burden of disease is treated primarily through surgery, and among surgical conditions, treating clefts conveys disproportionately large benefit relative to cost because suffering can be halted at a young age and deliver a lifetime of health. Over the last 50 years, cleft care has advanced in low-resource settings through international surgical missions and the efforts of sparse local providers. While exciting anecdotes of impact abound from these efforts, recent studies have identified a complication rate that often exceeds 50% and there is concern about the sustainability of foreign volunteer missions. This book serves as a thorough resource for providing medical and surgical care of cleft lip and palate deformities in low-resource settings, geared to the context of those settings. The content is consensus-based and evidence-based, with emphasis on treatment that is appropriate to a low-resource context and how this differs from that in higher-resource environments. It is authored by recognized cleft experts in close partnership with providers who practice in low-resource settings. It is heavily pictorially based through illustrative figures, photos and diagrams, to be facile for those who speak English as a second language. Following the introduction, Complete Cleft Care in Low-Resource Settings has six main sections: patient workup, surgical treatment, comprehensive care, educational innovation, care delivery models, and finally a series of illustrative case studies. Uniquely, the book’s breadth encompasses cleft care comprehensively, but does so through a practical “how to” format with many “from the field” examples of what has worked.
