A New Measure of Posterior Morphology in Sagittal Craniosynostosis: The Occipital Bullet Index.

INTRODUCTION: Sagittal craniosynostosis (SC) is associated with scaphocephaly, an elongated narrow head shape. Assessment of regional severity in the scaphocephalic head is limited by the use of serial computed tomographic (CT) imaging or complex computer programing. Three-dimensional measurements of cranial surface morphology provide a radiation-free alternative for assessing cranial shape. This study describes the creation of an occipital bulleting index (OBI), a novel tool using surface morphology to assess the regional severity in patients with SC. METHODS: Surface imaging from CT scans or 3D photographs of 360 individuals with SC and 221 normocephalic individuals were compared to identify differences in morphology. Cartesian grids were created on each individual's surface mesh using equidistant axial and sagittal planes. Area under the curve (AUC) analyses were performed to identify trends in regional morphology and create measures capturing population differences. RESULTS: The largest differences were located in the medial regions posteriorly. Using these population trends, a measure was created to maximize AUC. The OBI has an AUC of 0.72 with a sensitivity of 74% and a specificity of 61%. When the frontal bossing index is applied in tandem, the two have a sensitivity of 94.7% and a specificity of 93.1%. Correlation between the two scores in individuals with SC was found to be negligible with an intraclass correlation coefficient of 0.018. Severity was found to be independent of age under 24 months, sex, and imaging modality. CONCLUSIONS: This index creates a tool for differentiating control head shapes from those with SC and has the potential to allow for objective evaluation of the regional severity, outcomes of different surgical techniques, and tracking shape changes in individuals over time, without the need for radiation.

Spring-Assisted Surgery for Treatment of Sagittal Craniosynostosis.

ABSTRACT: Craniosynostosis (CSS), the premature fusion of calvarial sutures, most commonly involves the sagittal suture. Cranial vault remodeling (CVR) is a traditional method of CSS correction. Minimally invasive methods are becoming widely accepted, including spring-assisted surgery (SAS). The equipment required for SAS is minimal therefore adaptable to resource challenged health systems. This paper outlines the experience of SAS in Moldova.A retrospective study was performed for patients treated with SAS for sagittal CSS from 2011 to 2018 in Moldova. Perioperative data were recorded including age, length of surgery, blood loss, volume transfused and length of stay. Four patients had pre- and post-operative computed tomography (CT) scans which were used to calculate changes in cephalic index, normative cephalic index, and intracranial volume.Thirteen patients underwent SAS. Diagnoses were made clinically and confirmed with CT. Mean age at surgery was 4.0 months, and length of surgery 62.7 minutes. All but one patient received a blood transfusion, as is standard of practice in Moldova. The mean length of post-operative recovery in ICU was 30.9 hours. No complications required surgical revision. Springs were removed after 4 to 5 months. All patients had a subjective improvement in scaphocephaly. Based on the available CT scans, an increase in cephalic index (7.3%), normative cephalic index (11.8%), and intracranial volume (38.1%) was observed. One patient underwent SAS at 11 months and required cranioplasty for asymmetry at the time of spring removal.SAS is a safe and cost-effective method of CSS correction that can be utilized in countries with limited health system resources.

Comparison of 2 Sagittal Craniosynostosis Repair Techniques: Spring-Assisted Surgery Versus Endoscope-Assisted Craniectomy With Helmet Molding Therapy.

INTRODUCTION: This study compares anthropometric outcomes of 2 sagittal synostosis repair techniques: spring-assisted surgery and endoscope-assisted craniectomy with molding helmet therapy. METHODS: Patients undergoing spring-assisted surgery (n = 27) or endoscope-assisted craniectomy with helmet therapy (n = 40) at separate institutions were retrospectively reviewed. Pre- and 1-year postoperative computed tomography (CT) or laser scans were analyzed for traditional cranial index (CI), adjusted cranial index (aCI), and cranial vault volume (CVV). Nine patient-matched scans were analyzed for measurement consistency. RESULTS: The spring-assisted group was older at both time points (P < .050) and spring-assisted group CVV was larger preoperatively and postoperatively (P < .01). However, the change in CVV did not differ between the groups (P = .210). There was no difference in preoperative CI (helmet vs spring: 70.1 vs 71.2, P = .368) between the groups. Postoperatively, helmet group CI (77.0 vs 74.3, P = .008) was greater. The helmet group also demonstrated a greater increase in CI (6.9 vs 3.1, P < .001). The proportion of patients achieving CI of 75 or greater was not significantly different between the groups (helmet vs spring: CI, 65% vs 52%, P = .370). There was no detectable bias in CI between matched CT and laser scans. Differences were identified between scan types in aCI and CVV measurements; subsequent analyses used corrected CVV and aCI measures for laser scan measures. CONCLUSIONS: Both techniques had equivalent proportions of patients achieving normal CI, comparable effects on cranial volume, and similar operative characteristics. The study suggests that there may be greater improvement in CI in the helmet group. However, further research should be performed.

Factors associated with the use of vertical rectus abdominus myocutaneous flap reconstruction following abdominoperineal resection for anorectal cancer.

BACKGROUND AND OBJECTIVES: Following abdominoperineal resection (APR), primary closure of the perineal defect is often possible. Some patients, however, require flap reconstruction. Identifying these patients preoperatively is critical to facilitate comprehensive patient counseling and optimize surgical efficacy. METHODS: A retrospective review of patients undergoing APR over a 10-year period was performed to identify predictive factors for patients requiring reconstruction with a vertical rectus abdominis myocutaneous (VRAM) flap as opposed to primary closure. Student's t and Fisher's exact tests were utilized for statistical analysis. RESULTS: A total of 158 patients underwent APR, 29 of whom (18%) required a VRAM flap. A higher average skin resection area was seen among those requiring flap reconstruction (P < .0001). Flap reconstruction was also associated with current smoking status (P = .0197), anal tumor location (P < .0001), and neoadjuvant radiation (P = .0457). Although not statistically significant, average tumor diameter was larger in the VRAM flap group compared with the primary closure group. CONCLUSIONS: While the appropriate method of closure for those undergoing APR should be considered on an individual case basis, patients who smoke, have a tumor located at the anus, or require large skin resection are more likely to need flap reconstruction.

The History of Spring-Assisted Surgery Implementation into the Treatment Algorithm for Craniofacial Deformities.

Spring-assisted surgery has been a part of the craniofacial surgeon's armamentarium for more than 2 decades now. The development and implementation of this technique will be reviewed as well as the evolution of spring surgery at Wake Forest University.

Outcomes of Endoscopic Versus Open Spring Assisted Surgery for Sagittal Craniosynostosis.

Spring-assisted surgery (SAS) has been shown to be an effective technique for correction of isolated sagittal craniosynostosis in patients less than 6 months of age. At their institution, the authors adopted a minimally invasive technique in 2010, using a shorter incision and an endoscope. A retrospective chart review of 101 patients with isolated, nonsyndromic, sagittal craniosynostosis, who underwent SAS, was performed in order to compare perioperative and clinical outcomes of the open (n = 51) and minimally-invasive (n = 50) approaches. Surgeries were performed by 2 neurosurgeons and 3 plastic surgeons, between 2005 and 2018. The pre and postoperative cephalic indices were not significantly different in both groups. Minimally-invasive spring placement required a longer operative time than the open approach, with the mean minimally-invasive operative time at 65 minutes, compared to 53 minutes (P < 0.0001). Spring removal operative time was not significantly different, with the minimally-invasive operative time at 31 minutes versus 29 minutes (P = 0.48). There were no significant differences in major or minor complications when comparing the open and minimally-invasive approaches. In conclusion, both the open and the minimally-invasive SAS techniques are effective for early correction of isolated sagittal craniosynostosis, although the minimally-invasive approach requires a longer operative time for spring placement.

Spring-Assisted Strip Craniectomy Versus Cranial Vault Remodeling: Long-Term Psychological, Behavioral, and Executive Function Outcomes.

BACKGROUND: Controversy exists regarding the optimal surgical approach for non-syndromic sagittal synostosis. This study provides the first comparative analysis of the long-term behavioral, psychological, and executive function outcomes for patients who underwent either cranial vault remodeling (CVR) or spring-assisted strip craniectomy (SAS). METHODS: Thirty-six CVR patients and 39 SAS patients were evaluated. Parents and caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF) and the Behavior Assessment System for Children, Second Edition (BASC-2) to evaluate behavioral, emotional, social, adaptive, and executive functioning skills. RESULTS: There were no statistically significant differences between the CVR and the SAS groups (P > 0.05) in any of the BRIEF areas of function. Furthermore, the BASC-2 battery illustrated no significant differences in all areas analyzed except one. Among the 2 groups, the CVR group was rated as having fewer social withdrawal symptoms on the BASC-2 (47.00 ±â€Š10.27) compared to the SAS cohort (54.64 ±â€Š10.96), F = 6.79, P = 0.012, Cohen d = 0.688. However, both means were still within the normal range. CONCLUSIONS: Children undergoing SAS and CVR procedures for isolated sagittal synostosis were not rated as having clinically significant behavioral, emotional, social, adaptive, or executive functioning problems on parental forms.

Multi-Omics Revealed Molecular Mechanisms Underlying Guard Cell Systemic Acquired Resistance.

Systemic Acquired Resistance (SAR) improves immunity of plant systemic tissue after local exposure to a pathogen. Guard cells that form stomatal pores on leaf surfaces recognize bacterial pathogens via pattern recognition receptors, such as Flagellin Sensitive 2 (FLS2). However, how SAR affects stomatal immunity is not known. In this study, we aim to reveal molecular mechanisms underlying the guard cell response to SAR using multi-omics of proteins, metabolites and lipids. Arabidopsis plants previously exposed to pathogenic bacteria Pseudomonas syringae pv. tomato DC3000 (Pst) exhibit an altered stomatal response compared to control plants when they are later exposed to the bacteria. Reduced stomatal apertures of SAR primed plants lead to decreased number of bacteria in leaves. Multi-omics has revealed molecular components of SAR response specific to guard cells functions, including potential roles of reactive oxygen species (ROS) and fatty acid signaling. Our results show an increase in palmitic acid and its derivative in the primed guard cells. Palmitic acid may play a role as an activator of FLS2, which initiates stomatal immune response. Improved understanding of how SAR signals affect stomatal immunity can aid biotechnology and marker-based breeding of crops for enhanced disease resistance.

Obstructive Sleep Apnea Secondary to Pharyngeal Narrowing From Horizontal Donor Site Closure During Posterior Pharyngeal Flap Surgery.

The posterior pharyngeal flap is frequently the surgical intervention of choice for the correction of velopharyngeal insufficiency. Our patient initially presented for a superiorly based, posterior pharyngeal flap to correct for velopharyngeal insufficiency. However, the postoperative recovery was complicated by severe obstructive sleep apnea, which warranted division and subsequent takedown of the flap. Despite flap takedown, our patient's obstructive sleep apnea persisted. The patient's clinical course suggests that donor site closure, and not the actual pharyngeal flap, caused the persistent obstructive sleep apnea.

Provision and Utilization of Team- and Community-Based Operative Care for Patients With Cleft Lip/Palate in North Carolina.

OBJECTIVE: To characterize operative care for cleft lip and/or palate (CL/P) based on location (ie, from American Cleft Palate Craniofacial Association [ACPA]-approved multidisciplinary teams or from community providers). DESIGN: Cross-sectional analysis of Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery & Services Database databases for North Carolina from 2012 to 2015. SETTING/PATIENTS AND MAIN OUTCOME MEASURES: Clinical encounters for children with CL/P undergoing operative procedures were identified, classified by location as "Team" versus "Community," and characterized by demographic, geographic, clinical, and procedural factors. A secondary evaluation reviewed concordance of team and community practices with an ACPA guideline related to coordination of care. RESULTS: Three teams and 39 community providers performed a total of 3010 cleft-related procedures across 2070 encounters. Teams performed 69.7% of total volume and performed the majority of cleft procedures, including cleft lip repair, palate repair, alveolar bone grafting, and correction of velopharyngeal insufficiency. Community locations principally offered myringotomy and rhinoplasty. Team care was associated with higher guideline concordance. CONCLUSIONS: American Cleft Palate Craniofacial Association -approved team-based care accounts for the majority of cleft-related care in North Carolina; however, a substantial volume of cleft-related procedures was provided by community providers, with 3 providers accounting for the vast majority of community cases.

Outcomes Analysis of Chief Cosmetic Clinic Over 13 Years.

BACKGROUND: Adequate resident training in aesthetic surgery has become increasingly important with rising demand. Chief resident aesthetic clinics allow hands on experience with an appropriate amount of autonomy. The purpose of this study was to compare resident cosmetic clinic outcomes to those reported in the literature. Furthermore, we sought to assess how effective these clinics can be in preparing residents in performing common aesthetic surgery procedures. METHOD: A retrospective chart review of 326 patients and 714 aesthetic procedures in our chief cosmetic clinic over a 13-year period was performed, and complication and revision rates were recorded. In addition, an electronic survey was sent to 26 prior chief residents regarding their experience and impressions of the chief resident aesthetic clinic. RESULT: A total of 713 procedures were performed on 326 patients. Patient ages ranged from 5 to 75 years old (mean, 40.8 years old) with a mean follow-up of 76.2 days. On average, there were 56 procedures performed per year. Of the 714 total procedures performed, there were 136 minor procedures and 578 major procedures. Of the 136 minor procedures, there were no complications and there was 1 revision of a cosmetic injection. Of the 578 major procedures, the overall complication rate was 6.1% and the revision rate was 12.8%. Complication and revision rates for each individual surgery were further analyzed and compared with the literature. The complication rates for these procedures fell within the reference ranges reported. In regards to the chief resident survey, there was a 77% response rate. All respondents reported that the chief resident clinic positively affected their residency education and future practice. Ninety percent of respondents felt "very comfortable" performing facelifts, body contouring, and aesthetic breast surgery. No respondents completed a subsequent cosmetic fellowship, and 60% stated that their positive experience in chief clinic contributed to their decision not to pursue a cosmetic fellowship. CONCLUSIONS: Chief resident clinics can provide results with acceptable complication and revision rates that fall within the acceptable ranges in the literature. In addition, it provides a valuable experience that leaves residents with high comfort levels in performing key procedures in aesthetic surgery.

Plastic Surgery Resident-Run Cosmetic Clinics: A Survey of Current Practices.

BACKGROUND: The recently increased minimum aesthetic surgery requirements set by the Plastic Surgery Residency Review Committee of the Accreditation Council for Graduate Medical Education highlight the importance of aesthetic surgery training for plastic surgery residents. Participation in resident aesthetic surgery clinics has become an important tool to achieve this goal. Yet, there is little literature on the current structure of these clinics. OBJECTIVES: The authors sought to evaluate current practices of aesthetic resident-run clinics in the United States. METHODS: A survey examining specific aspects of chief resident clinics was distributed to 70 plastic surgery resident program directors in the United States. Thirty-five questions sought to delineate clinic structure, procedures and services offered, financial cost to the patient, and satisfaction and educational benefit derived from the experience. RESULTS: Fifty-two questionnaires were returned, representing 74.2% of programs surveyed. Thirty-two (63%) reported having a dedicated resident aesthetic surgery clinic at their institution. The most common procedures performed were abdominoplasty (n = 20), breast augmentation (n = 19), and liposuction (n = 16). Most clinics offered neuromodulators (n = 29) and injectable fillers (n = 29). The most common billing method used was a 50% discount on surgeon fee, with the patient being responsible for the entirety of hospital and anesthesia fees. Twenty-six respondents reported feeling satisfied or very satisfied with their resident aesthetic clinic. CONCLUSIONS: The authors found aesthetic chief resident clinics to differ greatly in their structure. Yet the variety of procedures and services offered makes participation in these clinics an effective training method for the development of both aesthetic surgical technique and resident autonomy.

Long-Term Outcomes of Pediatric Cranial Reconstruction Using Resorbable Plating Systems for the Treatment of Craniosynostosis.

BACKGROUND: Resorbable plating in cranial reconstruction for craniosynostosis has fewer reported complications than rigid hardware. Few long-term outcome studies exist for pediatric patients treated with this technology for cranial vault reconstruction. METHODS: A retrospective review was performed on pediatric patients undergoing cranial vault reconstruction for craniosynostosis by 3 surgeons over a 15-year period. MacroPore (Cytori Therapeutics, San Diego, CA) or Lactosorb (Walter Lorenz Surgical Inc, Jacksonville, FL), composed of polyglycolic and polylactic acids, was used for resorbable plate fixation. RESULTS: A total of 203 patients underwent resorbable plate fixation with a mean age of 15.8 months at surgery. Mean length of follow-up was 6.4 years. Lactosorb plating system was used in the majority of patients (74%) compared with MacroPore plating system (26%). Overall, unplanned reoperations were required in 5.4% of patients. Palpable hardware was noticed in 10.3% of patients. Only 3 patients (1.5%) developed exposure of the resorbable hardware requiring removal, all MacroPore plates. Four patients (2%) developed surgical site infection and 3 patients (1.5%) developed a seroma. There were 15.8% requiring later surgical revision with cranial vault expansion or cranioplasty with grafts for residual cranial defects. The majority of revisional reoperations (81%) occurred in the first half of the study before the addition of Allogenix. CONCLUSIONS: Resorbable plating systems, specifically Lactosorb, for cranial reconstruction are a safe, reproducible, inexpensive modality with very low complication rates. They have 3-dimensional stability, rigid fixation without causing growth restriction, and lower likelihood of need for removal.

Salinity Response in Chloroplasts: Insights from Gene Characterization.

Salinity is a severe abiotic stress limiting agricultural yield and productivity. Plants have evolved various strategies to cope with salt stress. Chloroplasts are important photosynthesis organelles, which are sensitive to salinity. An understanding of molecular mechanisms in chloroplast tolerance to salinity is of great importance for genetic modification and plant breeding. Previous studies have characterized more than 53 salt-responsive genes encoding important chloroplast-localized proteins, which imply multiple vital pathways in chloroplasts in response to salt stress, such as thylakoid membrane organization, the modulation of photosystem II (PS II) activity, carbon dioxide (CO2) assimilation, photorespiration, reactive oxygen species (ROS) scavenging, osmotic and ion homeostasis, abscisic acid (ABA) biosynthesis and signaling, and gene expression regulation, as well as protein synthesis and turnover. This review presents an overview of salt response in chloroplasts revealed by gene characterization efforts.

A Systematic Approach to Predicting Spring Force for Sagittal Craniosynostosis Surgery.

Spring-assisted surgery (SAS) can effectively treat scaphocephaly by reshaping crania with the appropriate spring force. However, it is difficult to accurately estimate spring force without considering biomechanical properties of tissues. This study presents and validates a reliable system to accurately predict the spring force for sagittal craniosynostosis surgery. The authors randomly chose 23 patients who underwent SAS and had been followed for at least 2 years. An elastic model was designed to characterize the biomechanical behavior of calvarial bone tissue for each individual. After simulating the contact force on accurate position of the skull strip with the springs, the finite element method was applied to calculating the stress of each tissue node based on the elastic model. A support vector regression approach was then used to model the relationships between biomechanical properties generated from spring force, bone thickness, and the change of cephalic index after surgery. Therefore, for a new patient, the optimal spring force can be predicted based on the learned model with virtual spring simulation and dynamic programming approach prior to SAS. Leave-one-out cross-validation was implemented to assess the accuracy of our prediction. As a result, the mean prediction accuracy of this model was 93.35%, demonstrating the great potential of this model as a useful adjunct for preoperative planning tool.

Management of Severe Microstomia in a Ten-Week-Old Infant.

Microstomia is rarely seen in pediatric patients, but usually results from burns, trauma, or caustic ingestions. There have been multiple studies reporting various techniques for oral commissure reconstruction, but few reports in infants. The authors present another modification of previous techniques of microstomia repair performed in a 10-week-old infant using multiple z-plasties and bilateral mucosal rhomboid flaps.

The Use of Brainlab Navigation in Le Fort III Osteotomy.

Le Fort III osteotomy is commonly used in the surgical correction of midface hypoplasia, specifically in patients with syndromic craniosynostosis. These osteotomies can be associated with significant complications, which are often the result of incomplete or inaccurate osteotomies. Brainlab, a technology first developed for neurosurgery, has been applied to numerous surgical subspecialties. The aim of this study was to report our initial experience using the Brainlab VectorVision2 and Brainlab Curve (Brainlab, Westchester, IL) as an intraoperative guidance system for osteotomy placement during Le Fort III advancement. Three pediatric patients with syndromic craniosynostosis and midface hypoplasia scheduled to undergo Le Fort III advancement were scanned preoperatively with 0.6-mm computed tomography cuts, which were then uploaded to the Brainlab system. All surgeries commenced with rigid fixation of the Brainlab registration device to the patient's skull. The navigation system was used intraoperatively to accurately determine osteotomy sites and trajectories. External distractors were placed without complication. Mean length of surgery was 331 minutes, and mean estimated blood loss was 500 mL. No transfusion was required with a mean postoperative hemoglobin of 8.3 g/dL. The application of Brainlab technology to Le Fort III advancement proved useful in establishing precise osteotomy lines and trajectories. Looking forward, this technology could be applied to a minimal dissection technique in order to avoid extensive blood loss. Further study would be needed to determine possible benefits such as reduced complications or operative time when using an intraoperative navigation system for image-guided osteotomy placement during Le Fort III advancement.

Analysis of Pediatric Maxillofacial Fractures Requiring Operative Treatment: Characteristics, Management, and Outcomes.

Maxillofacial fractures in pediatric trauma patients require significant force and frequently are associated with concomitant injuries. The anatomic and developmental differences between the adult and child that impact patterns of injury also affect management and outcomes. The aim of this study was to analyze fracture location, mechanism, concomitant injuries as well as methods of surgical treatment and outcomes, to improve management of this patient population. A retrospective review was conducted of pediatric patients with maxillofacial fractures presenting to a level-1 trauma center during an 8-year span. Only patients requiring surgical intervention, 204, were included in this study. Data pertaining to the location of injury, mechanism, associated injuries, surgical treatment, outcomes, and complications were analyzed. The most common fracture location was the mandible (36.3%), then the nasal bone (35.3%), followed by the tripod fracture (10.8%). A total of 30.7% of patients were involved in motor vehicle accidents, with the next most common mechanisms being sports (24.4%), and assault (13.7%). A total of 46% of the patients sustained concomitant injuries, with the majority involving cerebral trauma (14.7%) or the extremities (9.3%). Total 75.4% of all fractures, excluding the nose, were treated with open reduction and internal fixation (ORIF). Our complication rate was 11.2%. Pediatric craniofacial trauma remains a frequent presentation to the emergency department of trauma centers. Facial fracture patterns and mechanism of trauma observed in the pediatric population presenting to this facility are consistent with incidences reported in the literature. Knowledge of treatment options and potential complications is an important tool in the management of the pediatric trauma patient.

Outcomes of Vacuum-Assisted Therapy in the Treatment of Head and Neck Wounds.

INTRODUCTION: Head and neck wounds can present a reconstructive challenge for the plastic surgeon. Whether from skin cancer, trauma, or burns, there are many different treatment modalities used to dress and manage complex head and neck wounds. Vacuum-assisted closure (VAC) therapy has been used on wounds of nearly every aspect of the body but not routinely in the head and neck area. This study was conducted to demonstrate our results using the VAC in the treatment of complex head and neck wounds. METHODS: This is an IRB-approved, retrospective review of 69 patients with 73 head and neck wounds that were managed using the VAC between 1999 and 2008. The wound mechanism, location, and size, length of VAC therapy, patient comorbidities, use of radiation, complications, and ultimate outcome were assessed. In this patient population, the VAC was utilized because the standard reconstructive ladder was not a good option or had previously failed. RESULTS: Sixty-nine patients with complex head and neck wounds were treated with the wound VAC. The mean age of the patients was 66 years, with a range of 5-96 years. Males outnumbered females in this study nearly 2:1. Eighty-six percent of patients had wounds secondary to cancer, 8% secondary to trauma, 3% secondary to infection, and 3% secondary to burns. The VAC was used as a dressing over skin grafts in 50%, over Integra in 21%, and over open debrided wounds in 29%. Wounds healed without complication in 44% of the skin grafts, 67% of Integra-covered wounds, and 71% of debrided wounds. Minor complications included failure of complete graft take, failure of granulation tissue formation in open debrided wounds, infection, and hematoma formation under skin grafts. Major complications included positive cancer margins requiring reexcision and death secondary to pulmonary embolism, sepsis, and metastatic cancer. Most complications resolved with dressing changes, repeat grafting, or the administration of antibiotics. CONCLUSIONS: Our results demonstrate that the wound VAC provides a reliable, effective, and durable dressing for a multitude of complex head and neck wounds. Additionally, it is a valuable tool when traditional surgical procedures are not a viable option.

Deformational plagiocephaly and craniosynostosis: trends in diagnosis and treatment after the "back to sleep" campaign.

BACKGROUND: In 1992, the American Academy of Pediatrics discouraged prone sleeping positions because of its association with sudden infant death syndrome. After this was an increased incidence of deformational plagiocephaly (DP). METHODS: A retrospective review was completed for patients with DP and craniosynostosis seen by plastic surgeons at a tertiary medical center during a 19-year period. Two groups of patients were evaluated before (1988-1995) and after (1996-2007) implementation of the "Back to Sleep" campaign. RESULTS: Of the 5169 patients, those with craniosynostosis (n = 279) had a mean age at initial evaluation before and after 1996 of 12.4 versus 5.6 months (P = 0.0008). There was a trend of decreasing age at initial evaluation and first surgery after 1996. For patients with DP (n = 4890), the mean age at initial evaluation before and after 1996 was 11.5 versus 6.0 months (P = 0.10). There was a trend of decreasing age at initial evaluation and DP correction after 1996. The majority of patients had right-sided DP (50.2%), followed by left-sided (24.7%) and bilateral (18.9%). There was no significant difference in DP correction rate (67% versus 87%) or the mean age that DP was corrected (12.8 versus 11.8 mo) before and after 1996. Compared with 1996 to 1999, there was a 214% and 390% increase in DP referrals from 2000 to 2003 and 2004 to 2007. For craniosynostosis, there was a 27% and 129% increase in referrals. CONCLUSIONS: The increasing incidence of DP since the Back to Sleep campaign is concerning, but a positive outcome is that patients are being referred and treated at a younger age.
