Background: Alveolar bone grafting is utilized to manage alveolar clefts in patients with cleft lip and palate. However, the timing of bone grafting is variable with conflicting evidence supporting the use of primary alveolar bone grafting (PABG) in clinical practice. Primary Aim: To provide a qualitative systematic review analysis of long-term outcomes after PABG. Materials and Methods: A qualitative systematic review was performed following the Cochrane Handbook and reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Summative findings were evaluated using Confidence in the Evidence from Reviews of Qualitative research to assess the quality of evidence supporting the findings. Results: After removing duplication, 2182 publications were identified, and 2131 were excluded after screening through titles and abstracts. Inclusion criteria for this study included patients who underwent PABG at 24 months of age or younger and a minimum of 5 year follow-up. Thirty-two publications met the inclusion criteria and were included for qualitative analysis. Primary outcome measures included cephalometric analysis, bone graft survival, occlusal analysis, hypomineralization, tooth eruption, radiograph analysis, and arch relationships. Four assessment themes were characterized from the systematic review: (1) bone graft survival, (2) craniofacial skeletal relationships, (3) occlusion and arch forms, and (4) recommendations for utilizing PABG in practice. Conclusion: The reported systematic review provides evidence that performing PABG leads to poor long-term outcomes related to bone graft survival and maxillary growth restriction despite some reported positive outcomes.
Background
Calculation of intracranial volume from neuroimaging can be complex and time consuming. In the adult population, there is evidence suggesting that owing to its strong correlation, head circumference (HC) may be used as a surrogate for intracranial volume (ICV). We were interested in studying the correlation between HC and ICV in patients with craniosynostosis.
Methods
After institutional review board approval, a retrospective review was performed on patients with craniosynostosis. GE Healthcare AdW 4.3 volume assessment software was used to calculate ICV and HC based on preoperative computed tomographic scans. Pearson correlation was used to estimate correlation coefficients between ICV and HC for this patient population, with 0 to 0.3 considered a weak correlation, 0.4 to 0.6 considered a moderate correlation, 0.7 to 1 considered a strong correlation, and P < 0.05 was considered statistically significant.
Results
A total of 196 craniosynostosis patients were included in this study. There were 121 male and 75 female patients. Seventy-nine patients had metopic, 45 had coronal, 64 had sagittal, and 8 had lambdoid synostosis. Mean age was 8.2 months. Mean HC and ICV were 42.9 cm and 829 cm3, respectively. Overall, there was a strong correlation between HC and ICV (r = 0.81). Patients were further categorized by craniosynostosis type. Very strong correlation was obtained for patients with coronal (0.89), metopic (0.98), and lambdoid craniosynostosis (0.97). Strong correlation was obtained for patients with sagittal synostosis (0.73). When categorized by sex, a stronger correlation was obtained for female patients (0.84) compared with male patients (0.80). Statistical significance was reached for all reported correlations.
Conclusion
Our preliminary data suggest that a very strong correlation exists between HC and ICV for male and female patients with all types of craniosynostosis, making HC a useful surrogate for ICV in this patient population.
Anecdotal evidence suggests that patients with isolated traumatic facial fractures have high narcotic usage, yet there is a lack of literature delineating this relationship. This study aimed to characterize total amount and factors predictive of narcotic usage following isolated traumatic facial fracture. Study participants (n ¼ 35) were predominantly male (91.4%), mean age 40.5, Caucasian (34.3%), suffered some form of assault (62.9%), and remained hospitalized for an average of 3.0 days. Average morphine milligram equivalent (MME) use in the inpatient setting was 967.6 for operative (n ¼ 30) and 37.5 for nonoperative (n ¼ 5) patients. Average total narcotic use across inpatient and outpatient settings was 1256.6 MME for operative and 105 MME for nonoperative patients. Operative intervention predicted a significant difference in total inpatient narcotic usage (P ¼ 0.009). For patients who underwent surgical intervention, significant variations in narcotic usage were found based on mechanism of injury (24-hour postoperative, P ¼ 0.030), but not injury severity or number of procedures. Specifically, individuals suffering highly traumatic fractures (eg, gunshot wound) demonstrated increased total postoperative narcotic usage of 1194.1 MME (P ¼ 0.004). Interestingly, non-narcotic analgesic use including acetaminophen and lidocaineepinephrine resulted in significantly lower narcotic usage in the postoperative setting. These findings suggest a role for narcoticreducing enhanced recovery after surgery protocols in the setting of isolated facial trauma.
Background
The aims of the current analysis were to study the change in ventricular volume (VV) obtained with cranial distraction in patients with craniosynostosis and compare it with the change in total intracranial volume (ICV) and brain volume.
Methods
After institutional review board approval, a retrospective review was performed on patients undergoing cranial distraction over a 5-year period. GE Healthcare AdW 4.3 volume assessment software was utilized to calculate preoperative and postdistraction ICV, VV, and whole-brain volume. Data were also collected on patient demographics, age at the time of distraction, time spent in distraction and consolidation, and length of stay. t Tests were used for comparison.
Results
Twenty-three patients met our inclusion criteria. Forty-eight percent of patients (n = 11) had right-sided cranial distraction, 30% (n = 7) had bilateral distraction, and 22% of patients (n = 5) had left-sided distraction. At the preoperative stage, mean head circumference was 42.5 ± 4.7 cm, mean ICV was 810.1 ± 27 cm3, mean non-VV (NVV) was 796.2 ± 268 cm3, and mean VV was 13.9 ± 9 cm3. After a mean of 27.4 mm of distraction, occurring over a mean of 26 days and consolidation period of 149 days, a second computed tomography scan was obtained. Mean postdistraction head circumference was 49.1 ± 3.9 cm, mean ICV was 1074.1 ± 203 cm3, mean NVV was 1053.5 ± 197 cm3, and VV was 20.6 ± 14 cm3. Mean % increase in ICV at this stage was 47.4%; mean % NVV increase was 48.5% as opposed to 60.3% increase in VV.
Conclusions
Cranial distraction is known to effectively increase ICV. Our study suggests that the effect of this volumetric increase is much more pronounced on the VV compared with the brain volume. Further studies are underway to investigate whether this short-term marked increase in VV is sustained over a long-term period.
