RESUMEN

BACKGROUND: Competent speech requires closure of the velopharyngeal sphincter by dynamic apposition of the velum and posterior and lateral pharyngeal walls. An accurate estimation of lateral pharyngeal wall motion is an important determinant in the planning and the outcome of any operation to correct velopharyngeal insufficiency (VPI). The purpose was to compare the assessment of lateral pharyngeal wall movement by videofluoroscopy (VP) versus nasopharyngoscopy (NP). METHODS: The authors retrospectively reviewed the charts of 269 consecutive patients in our cleft lip/palate clinic from 1982 to 2008 and culled those treated with a pharyngeal flap for VPI. The authors included patients who were evaluated preoperatively by both VP and NP, and had studies of suitable quality. Percentage of lateral pharyngeal wall motion was estimated with each technique and compared for each patient. RESULTS: The authors identified 25 patients who underwent both VP and NP at the same median age (4.7 years). The estimated percentage of lateral pharyngeal wall motion between the 2 techniques was significantly different ( P <0.001). Average lateral pharyngeal wall motion was estimated to be 59±25% (range: 5%-90%) by VP and only 40%±25% (range: 0%-95%) during NP. CONCLUSIONS: VP and NP are complementary, but assessment of lateral pharyngeal wall motion can vary between the 2 methods. The surgeon should be aware of the difference in estimated lateral pharyngeal wall movement when planning a procedure to correct VPI.

RESUMEN

OBJECTIVE: To assess whether children with torticollis have quantifiably greater facial asymmetry than their age-matched controls using 3-dimensional (3D) photogrammetry. DESIGN: We retrospectively analyzed patients diagnosed with torticollis and age-matched volunteers who underwent 3D photogrammetry of their faces. We calculated the root mean square deviation (RMSD) between native and reflected facial images, as a measure of asymmetry. Two observers independently measured RMSD values for all study participants. The Spearman correlation coefficient evaluated interobserver reliability. The Wilcoxon rank-sum test with Bonferroni adjusted P values for multiple comparisons. SETTING: Institutional. PARTICIPANTS: Twenty patients diagnosed with torticollis and 12 age-matched volunteers. Patients were analyzed on a computer database and volunteers were selected and consented in the hospital. We excluded patients with a history of facial trauma, facial operations, or other craniofacial diagnoses. INTERVENTIONS: Facial surface scans were obtained using the Canfield Vectra stereophotogrammetry system. The technology captures surface anatomy without radiation. MAIN OUTCOME MEASURES: RMSD comparisons between patients with torticollis and age-matched controls. RESULTS: Compared to controls, patients with torticollis had statistically significant greater full face, upper third, and middle third facial asymmetry. There was a trend toward greater asymmetry of the lower facial third. CONCLUSIONS: We used 3D photogrammetry to quantitate facial asymmetry from torticollis. We found greater asymmetry in patients with torticollis than in their unaffected peers. All areas of the face appeared to be affected, though the asymmetry in the lower facial third just failed to reach significance.

RESUMEN

A study of a 22-year-old male who was assaulted and sustained a left orbital floor blowout fracture was presented in this study. The orbital floor was repaired with a titanium-reinforced porous polyethylene implant. Two years postoperatively, the patient sustained repeated left orbital trauma. The orbital floor implant remained stable while the medial wall blew out.

RESUMEN

The authors present the case of a 32-year-old patient treated for a left, isolated zygomatic fracture following assault. The injury was reduced without fixation via the Keene approach. The same patient presented to the emergency room 16 months later with a right-sided fracture similar to the previous contralateral injury. This fracture was left untreated. Repeated assaults over a 4-year period provide us with a natural history of both injuries, allowing for comparison between the 2 approaches. The authors found that reduction of the arch without fixation led to an outcome without palpable or visible deformity and no impaired mastication. Additionally, considering etiology of injury, such as alcohol or drug use, treatment may provide an important point of intervention to prevent recurrence.

RESUMEN

Langerhans cell histiocytosis (LCH) commonly affects the craniofacial skeleton and prognosis depends on location, extension, and recurrence of the disease. The aim of our study is to better define the treatment of single craniofacial lesions, as to date different treatment modalities have been suggested and recurrence rates for both unifocal and multifocal bony lesion range between 10% and 70%. Between 2000 and 2014, we retrospectively reviewed clinical findings, anatomic location, extent of the disease, therapy, and outcomes in 24 pediatric patients with histologically confirmed LCH. Seventeen patients (67%) had craniofacial involvement, of which 13 had single system involvement and 4 had multisystem involvement. Eight patients (33%) had no craniofacial involvement. Eleven patients affected by unifocal cranial lesions were treated with resection and reconstruction. One patient with a unifocal mastoid lesion was treated with chemotherapy alone (vinblastine and prednisone). Four patients with mandible lesions were treated with curettage alone.There were no recurrences in patients treated with excision alone. One patient (25%) treated with curettage recurred. Two patients with diffuse disease manifested organ dysfunction and diabetes insipidus. Chemotherapy was tolerated in 12 patients treated.Our findings suggest that resection of isolated LCH lesions of the cranium is safe and chemotherapy is effective and well tolerated for nonsurgical cases.

RESUMEN

OBJECTIVE: To evaluate 3-dimensional (3-D) photogrammetry as a tool for assessing the postoperative head shape of patients who had undergone cranial vault remodeling for metopic synostosis. DESIGN: We prospectively analyzed images of patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls. To ensure standardized facial orientation, each 3-D image was positioned to "best fit" the preoperative face by aligning 6 soft tissue landmarks. Forehead measurements were taken from a standardized position behind the surface of the face to landmarks placed in a ray configuration across the forehead. SETTING: Academic teaching hospital. PATIENTS, PARTICIPANTS: Thirteen pediatric patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls. INTERVENTIONS: Images were taken preoperatively, immediately postoperatively, and over 1-year postoperatively. MAIN OUTCOME MEASURES: Forehead contours preoperatively and postoperatively, with statistics performed using a multivariate analysis of variance shape analysis. RESULTS: Mean postoperative follow-up was 1.8 (0.6) years. The average distance from the origin to forehead landmarks was 55.1 (3.4) mm preoperatively, 59.3 (0.7) mm immediate postoperatively, 59.1 (1.0) mm 1-year postoperatively, and 59.4 (0.6) mm in controls. Postoperative metopic forehead contours varied significantly from preoperative contours ( P < .01), while there was no statistical difference between the 2 postoperative time points ( P = .70). One-year postoperative patients were not significantly different from their age-matched controls ( P > .99). CONCLUSIONS: Preoperative metopic forehead contours varied significantly from postoperative contours. Cranial reconstructions approximated the foreheads of normal controls, and reconstructions were stable at more than 1-year follow-up.

RESUMEN

OBJECTIVE: To evaluate nasal symmetry using three-dimensional photogrammetry following primary tip rhinoplasty with or without an internal splint in patients with unilateral complete cleft lip/palate. DESIGN: We captured three-dimensional images of patients with unilateral complete cleft lip/palate who underwent nasolabial repair by rotation-advancement of the lip and primary tip rhinoplasty, either with or without an internal resorbable splint, and normal control subjects. We assessed nasal symmetry by identifying the plane of maximum symmetry and the root-mean-square deviation between native and reflected surfaces. PATIENTS/PARTICIPANTS: We imaged 38 controls and 38 subjects with repaired unilateral complete cleft lip/palate (20 with, 18 without an internal splint). RESULTS: Nasal asymmetry root-mean-square deviation clustered between 0.19 and 0.50 mm (median = 0.24 ± 0.08 mm) for controls; whereas, those with repaired unilateral complete cleft lip/palate ranged from 0.4 to 1.5 mm (median = 0.75 ± 0.40 mm). Although root-mean-square deviation ranges overlapped, patients with repaired unilateral complete cleft lip/palate had significantly greater asymmetry than controls (P < .001). We found no difference in asymmetry between patients with or without an internal splint (P = .5). CONCLUSIONS: Three-dimensional photogrammetry was used to successfully compare symmetry among different patient and control groups. Although "normal" nasal symmetry was attained in some patients following cleft lip/nasal repair, most had persistent asymmetry compared with normal controls. Placement of a resorbable internal splint did not improve symmetry in patients with unilateral complete cleft lip/palate.

RESUMEN

BACKGROUND: The natural history of unrepaired craniosynostosis is not well defined. Delayed surgical intervention carries greater risk of postoperative complications and its functional benefits for older patients are poorly characterized. The authors reviewed patients in whom children presented beyond 1 year of age to better understand the natural history of craniosynostosis, and the risk-benefit relationship for delayed reconstruction. METHODS: After institutional IRB approval the authors conducted a retrospective review of patients who presented after 1 year of age with craniosynostosis. Type of craniosynostosis, age at evaluation, medical history, surgical findings, developmental abnormalities, ophthalmologic findings, and clinical course were reviewed. RESULTS: Ten patients with delayed presentation for craniosynostosis were identified. The mean age at presentation was 6.8 years ±â€Š4.2 years (range, 3-17 years). Seven of 10 patients presented with developmental delay. Five patients presented with debilitating headaches. Five patients presented with comorbid Chiari malformations, 3 of whom required surgical decompression. Two patients had papilledema. Four patients underwent intracranial pressure monitoring, with elevated pressures found in 3 patients. Six patients underwent delayed cranial vault remodeling. There were no peri- or postoperative complications, including infection or residual bony defects, in those undergoing delayed operation. CONCLUSIONS: Children who present in a delayed fashion with unrepaired craniosynostosis have high rates of debilitating headaches, developmental delays, head shape anomalies, and Chiari malformation. Five patients reporting preoperative headaches noted subjective improvements in headaches following delayed operation. Cranial reconstruction can be safely performed at an older age and is appropriate to consider in carefully selected patients for aesthetic and/or functional concerns.

RESUMEN

BACKGROUND: Orbital reconstruction requires knowledge of orbital depth in order to prevent optic nerve injury. Numerous analyses of adult orbital dimensions have been undertaken previously in order to characterize this measurement, including skull specimen and computerized tomography studies. However, there is a paucity of information regarding the pediatric orbit. METHODS: The authors used pediatric magnetic resonance imaging (MRI) studies in order to quantify the change in orbital depth in relationship to patient age, and to develop methods to estimate and calculate orbital depth for individual pediatric patients. MRIs of the head in normal pediatric patients were reviewed retrospectively. Orbital depths were measured and correlated with age and cephalometric dimensions. In a randomly selected subgroup of patients, measurements were repeated by an independent investigator to determine interobserver reliability. RESULTS: Measurements were obtained in 72 patients ranging from 3 months to 18 years of age (mean=7.8 years). There was a significant exponential relationship between orbital depth and patient age (r=0.81, F(2,69)=143.97, P<0.001). Depth increased more rapidly in the first 6 years of life, but leveled off in the early teen years toward a horizontal asymptote of approximately 45 mm. There was also a significant relationship between orbital depth and the sum of the biparietal width plus the anterior-posterior length (r=0.72, F(2,69)=87.44, P<0.0001). There was high interobserver reliability in measurements between 2 independent investigators (r=0.79, P<0.0001). CONCLUSION: In children, orbital depth increases predictably with rising age and increasing head size. Knowledge of this growth curve and the relationship between head size and orbital depth can complement careful surgical dissection to improve safety and efficacy in pediatric orbital reconstructions.

RESUMEN

BACKGROUND: Although symmetry is hailed as a fundamental goal of aesthetic and reconstructive surgery, our tools for measuring this outcome have been limited and subjective. With the advent of three-dimensional photogrammetry, surface geometry can be captured, manipulated, and measured quantitatively. Until now, few normative data existed with regard to facial surface symmetry. Here, we present a method for reproducibly calculating overall facial symmetry and present normative data on 100 subjects. METHODS: We enrolled 100 volunteers who underwent three-dimensional photogrammetry of their faces in repose. We collected demographic data on age, sex, and race and subjectively scored facial symmetry. We calculated the root mean square deviation (RMSD) between the native and reflected faces, reflecting about a plane of maximum symmetry. We analyzed the interobserver reliability of the subjective assessment of facial asymmetry and the quantitative measurements and compared the subjective and objective values. We also classified areas of greatest asymmetry as localized to the upper, middle, or lower facial thirds. This cluster of normative data was compared with a group of patients with subtle but increasing amounts of facial asymmetry. RESULTS: We imaged 100 subjects by three-dimensional photogrammetry. There was a poor interobserver correlation between subjective assessments of asymmetry (r = 0.56). There was a high interobserver reliability for quantitative measurements of facial symmetry RMSD calculations (r = 0.91-0.95). The mean RMSD for this normative population was found to be 0.80 ± 0.24 mm. Areas of greatest asymmetry were distributed as follows: 10% upper facial third, 49% central facial third, and 41% lower facial third. Precise measurement permitted discrimination of subtle facial asymmetry within this normative group and distinguished norms from patients with subtle facial asymmetry, with placement of RMSDs along an asymmetry ruler. CONCLUSIONS: Facial surface symmetry, which is poorly assessed subjectively, can be easily and reproducibly measured using three-dimensional photogrammetry. The RMSD for facial asymmetry of healthy volunteers clusters at approximately 0.80 ± 0.24 mm. Patients with facial asymmetry due to a pathologic process can be differentiated from normative facial asymmetry based on their RMSDs.

RESUMEN

Objective : Pediatric patients with skull defects larger than available sources for splitting bicortical bone have limited options for autogenous cortical bone cranioplasty. Piezoelectric instruments allow donor bone to be chosen based on the best possible contour rather than the presence of bicortical bone. We present the use of piezoelectric technology to split thin unicortical calvarium for autogenous cranioplasty in a series of pediatric patients. Design : Retrospective review of a series of pediatric patients requiring reconstruction for skull defects. Patients/Intervention : Our series included a 2-year-old with a parietal skull tumor and resultant 3 × 3-cm defect after craniectomy, a 2-year-old with a 3 × 3-cm defect after excision of an occipital skull tumor, a 10-year-old with a 4 × 5-cm skull defect after excision of an occipital skull tumor, and a 13-year-old who suffered a gunshot to the forehead with a 12 × 7-cm frontal skull defect. We used a piezoelectric saw to precisely and safely split unicortical and bicortical cranium that ranged from 1 to 3 mm in thickness. The inner layer was used to reconstruct the donor site; whereas, the outer layer was used for the craniectomy defect. Conclusion : The piezoelectric saw allows unicortical bone to be split and used for cortical bone cranioplasty. This technology allows choice of donor site based on the best contour rather than the presence of bicortical bone. This technique expands the possibilities of autogenous cranioplasty and enables primary repair of cranial defects that would otherwise require secondary cranioplasty with remote donor sites, foreign materials, or unstable particulate cranioplasty.

RESUMEN

PURPOSE: The pedicled reverse-flow lateral arm flap has been described primarily for the reconstruction of nontraumatic elbow wounds. We describe our experience using this flap in staged operations for soft tissue coverage after elbow trauma, including acute coverage of open fractures and salvage of infected hardware. METHODS: Review of patients who underwent staged pedicled reverse-flow lateral arm flap transfer for coverage of traumatic elbow defects. RESULTS: Three patients were identified; all underwent 2-stage repair with flap delay for coverage of traumatic elbow injuries. Each patient had stable wound coverage with this flap. The only complication was 5% distal flap necrosis in 1 patient. CONCLUSIONS: The pedicled reverse-flow lateral arm flap provides reliable soft tissue coverage of traumatic elbow defects with minimal donor-site morbidity.

RESUMEN

Reconstructive goals for orbitozygomaticomaxillary complex fractures include restoration of orbital volume, facial projection, and facial width. Delayed reconstruction is made more difficult by malunion, nonunion, bony absorption, loss of the soft tissue envelope, and scar. Three-dimensional intraoperative navigation, widely used in neurosurgery and sinus surgery, can improve the accuracy with which bony reduction is performed. This is particularly useful in the setting of bony absorption and comminution. We report a case of delayed reconstruction of an orbitozygomaticomaxillary complex fracture using intraoperative navigation and review this technology's utility in this setting.

RESUMEN

Excision of head and neck melanoma is often limited by critical structures, which can lead to incomplete excision with positive pathologic margin and increased local recurrence rate. Complete excision with recommended margins and immediate reconstruction is possible when surgical oncologists and plastic surgeons work collaboratively. Our purpose was to evaluate local recurrence rate after excision and immediate reconstruction. We reviewed 98 consecutive patients treated for primary head and neck cutaneous melanoma at a single institution between 1999 and 2004. We assessed local recurrence rate. A total of 72 patients (73%) were followed for an average of 5.2 ± 1.7 years while 26 patients were excluded due to less than 1 year of follow-up. Adjacent tissue transfer was the most common reconstruction (87%). Local recurrence was reported in 2.8% and distant metastasis in 12.5% of patients. Immediate reconstruction after excision of head and neck melanoma can be safely performed with low local recurrence rate.

RESUMEN

BACKGROUND: Craniosynostosis is typically diagnosed postnatally. Prenatal diagnosis would allow for improved parental counseling and facilitate timely intervention. Our purpose was to determine whether prenatal ultrasound can be used to diagnose nonsyndromic craniosynostosis. METHODS: The authors reviewed 22 prenatal ultrasounds of infants known to have nonsyndromic craniosynostosis and 22 age-matched controls. Cross-sectional images at the plane used to measure biparietal diameter were selected and cranial shape of each participant was parameterized and used to discriminate affected patients from controls. The results from quantitative shape analysis were compared with results from a blinded visual inspection alone. RESULTS: Among the 22 patients, the most common diagnosis was sagittal synostosis ( n = 11), followed by metopic synostosis ( n = 6). The average gestational age at time of ultrasound of controls and synostotic patients was 26 weeks and 6.8 days at the junction of the second and third trimesters. The controls and synostotic cases segregated into statistically different populations by their shape profiles ( p < 0.001). An automatic shape classifier using leave-one-out cross-validation correctly classified the 44 images as normal versus synostotic 85 percent of the time (sensitivity, 82 percent; specificity, 87 percent). Cephalic index was a poor indicator of sagittal synostosis (45 percent sensitivity). Visual inspection alone demonstrated only a fair level of accuracy (40 to 50 percent agreement) in identifying cases of synostosis (kappa, 0.09 to 0.23). CONCLUSIONS: Craniosynostosis can be identified on prenatal ultrasound with good sensitivity using formal shape analysis. Cephalic index and visual inspection alone performed poorly. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, II.

RESUMEN

BACKGROUND: The earthquake that struck Haiti on 12 January 2010 caused significant devastation to both the country and the existing healthcare infrastructure in both urban and rural areas. Most hospital and health care facilities in Port-au-Prince and the surrounding areas were significantly damaged or destroyed. Consequently, large groups of Haitians fled Port-au-Prince for rural areas to seek emergency medical and surgical care. In partnership with the Haitian Ministry of Health, Partners in Health (PIH) and Zanmi Lasante (ZL) have developed and maintained a network of regional and district hospitals in rural Haiti for over twenty-five years. This PIH/ZL system was ideally situated to accommodate the increased need for emergent surgical care in the immediate quake aftermath. The goal of the present study was to provide a cross-sectional assessment of surgical need and care delivery across PIH/ZL facilities after the earthquake in Haiti. METHODS: We conducted a retrospective review of hospital case logs and operative records over the course of three weeks immediately following the earthquake. RESULTS: Roughly 3,000 patients were seen at PIH/ZL sites by a combination of Haitian and international surgical teams. During that period 513 emergency surgical cases were logged. Other than wound debridement, the most commonly performed procedure was fixation of long bone fractures, which constituted approximately one third of all surgical procedures. CONCLUSIONS: There was a significant demand for emergent surgical care after the earthquake in Haiti. The PIH/ZL hospital system played a critical role in addressing this acutely increased burden of surgical disease, and it allowed for large numbers of Haitians to receive needed surgical services. Our experiences reinforce that access to essential surgery is an essential pillar in public health.

RESUMEN

BACKGROUND: The facial features of children with FGFR3Pro250Arg mutation (Muenke syndrome) differ from those with the other eponymous craniosynostotic disorders. We documented midfacial growth and position of the forehead after fronto-orbital advancement (FOA) in patients with the FGFR3 mutation. METHODS: We retrospectively reviewed all patients who had an FGFR3Pro250Arg mutation and craniosynostosis. Only patients who had FOA in infancy or early childhood were included. The clinical records were evaluated for type of sutural fusion; midfacial hypoplasia and other clinical data, including age at operation; type of procedures and fixation (wire vs resorbable plate); frequency of frontal readvancement, forehead augmentation, midfacial advancement; and complications. Preoperative and postoperative sagittal orbital-globe relationship was measured by direct anthropometry. Outcome of FOA was graded according to the Whittaker classification as category I, no revision; category II, minor revisions, that is, foreheadplasty; category III, alternative bony work; category IV; redo of initial procedure (ie, secondary FOA). Midfacial position was determined by clinical examination and lateral cephalometry. RESULTS: A total of 21 study patients with Muenke syndrome (8 males and 13 females) were analyzed. The types of craniosynostosis were bilateral coronal (n=15), of which 3 also had concurrent sagittal fusion, and unilateral coronal (n=5). Two patients had early endoscopic suturectomy, but later required FOA. Mean age at FOA was 22.9 months (range, 3-128 months). Secondary FOA was necessary in 40% of patients (n=8), and secondary foreheadplasty in 25% (n=5) of patients. No frontal revisions were needed in the remaining 35% of patients (n=7). Mean age at initial FOA was significantly younger in the group requiring repeat FOA or foreheadplasty compared with patients who did not require revision (P<0.05). Location of synostosis, type of fixation, and bone grafting did not significantly affect the need for revision. Only 30% (n=6) of patients developed midfacial retrusion. CONCLUSIONS: The frequency of frontal revision in patients with Muenke syndrome who had FOA in infancy and early childhood is lower than previously reported. Age at forehead advancement inversely correlated with the incidence of relapse and need for secondary frontal procedures. Midfacial retrusion is relatively uncommon in FGFR3Pro250Arg patients.

RESUMEN

OBJECTIVE: Our purpose was to compare speech outcomes among three primary procedures for symptomatic submucous cleft palate (SMCP): two-flap palatoplasty with muscular retropositioning, double-opposing Z-palatoplasty, or pharyngeal flap. DESIGN: Retrospective review. SETTING: Tertiary hospital. PATIENTS, PARTICIPANTS: All children with SMCP treated by the senior author between 1984 and 2008. INTERVENTIONS: One of three primary procedures: two-flap palatoplasty with muscular retropositioning, double-opposing Z-palatoplasty, or pharyngeal flap. MAIN OUTCOME MEASURES: Speech outcome and need for a secondary operation were analyzed among procedures. Success was defined as normal or borderline competent velopharyngeal function. Failure was defined as persistent borderline insufficiency or velopharyngeal insufficiency with recommendation for a secondary operation. RESULTS: We identified 58 patients with SMCP who were treated for velopharyngeal insufficiency. We found significant differences in median age at operation among the procedures (p < .001). Two-flap palatoplasty with muscular retropositioning (n = 24), double-opposing Z-palatoplasty (n = 19), and pharyngeal flap (n = 15) were performed at a median of 2.5, 3.6, and 9.5 years, respectively. There were significant differences in success among procedures (p = .018). Normal or borderline competent function was achieved in 6/20 (30%) patients who underwent two-flap palatoplasty, 10/15 (67%) following double-opposing Z-palatoplasty, and 11/12 (92%) following pharyngeal flap. Among patients treated with palatoplasty, success was independent of age at operation (p = .16). CONCLUSIONS: Double-opposing Z-palatoplasty is more effective than two-flap palatoplasty with muscular retropositioning. For children older than 4 years, primary pharyngeal flap is also highly successful but equally so as a secondary operation and can be reserved, if necessary, following double-opposing Z-palatoplasty.
