Reasons for Removal of Rigid Internal Fixation Devices in Craniofacial Surgery: A 20-year Update.

The hardware utilized for rigid internal fixation of the craniofacial skeleton has evolved over time. Thus, the reasons for the unplanned removal of hardware continue to change. The purpose of this study is to compare past (1989-1995) and present (2000-2020) patient cohorts to establish trends related to unplanned removal of craniofacial hardware. A retrospective review study was designed. Data from our institution's original publication describing the unplanned removal of craniofacial hardware (1989-1995) was obtained. Data related to patients who underwent unplanned removal of hardware from 2000 to 2020 was collected from the electronic medical record. A descriptive statistical analysis was performed to compare demographics, reasons for hardware placement, and reasons for unplanned hardware removal between cohorts. This study includes 55 patients treated from 1989 to 1995 and 184 patients treated from 2000 to 2020. The average age at hardware placement decreased from 32 years (1989-1995) to 28 years (2000-2020). The most common reason for hardware placement changed from motor vehicle accident (1989-1995) to congenital deformity (2000-2020). The length of time with hardware in situ increased from 13 months (1989-1995) to 25 months (2000-2020). The most common reason for hardware removal changed from prominent hardware (1989-1995) to hardware exposure (2000-2020). In summary, patients who underwent rigid internal fixation of the craniofacial skeleton from 2000 to 2020 retained their hardware 2 times longer than patients treated from 1989 to 1995. Factors potentially contributing to increased retention include improved surgical technique, decreased profile of hardware, and increased surgeon experience. Further studies are warranted to define preoperative risk factors for unplanned hardware removal.

A Simplified Approach to Myelomeningocele Defect Repair.

BACKGROUND: Repair of the soft tissue defect in myelomeningoceles remains challenging. The literature currently lacks a systematic approach, reporting high rates of complications. We present outcomes from the largest series to date and describe a simplified approach that minimizes morbidity and streamlines decision making. METHODS: Patients 1 year or younger who underwent myelomeningocele repair between 2008 and 2018 were reviewed. Flap types were categorized by tissue composition. Complications were dichotomized into early and late (<30 days and >30 days postoperative, respectively). Logistic regression was used to measure the impact of flap tissue composition and skin closure technique on odds of postoperative complications. RESULTS: Ninety-seven patients met inclusion criteria. Reoperation was required in only 3 (3.0%) patients-1 for wound dehiscence and 2 for surgical site infections. Zero cases of tethered cord or cerebrospinal fluid leak occurred. The most common minor complications were early wound complications (n = 18, 18.6%) and early infection (n = 5, 5.2%). Fascia-only flaps and muscle + other tissue flaps were not associated with higher odds of complications compared with muscle-only flaps (odds ratio [OR], 2.13; 95% confidence interval [CI], 0.53-8.50, P = 0.29; OR = 2.87, 95% CI 0.66-12.51, P = 0.16, respectively). Rhomboid flaps for skin closure were associated with higher odds of complications (OR, 4.47; 95% CI, 1.00-19.97; P = 0.05). CONCLUSIONS: Our approach to myelomeningocele repair demonstrated no cases of secondary tethered cord or cerebrospinal fluid leak, and reoperative rates were extremely low. Because complications were unrelated to flap type, we recommend a simplified approach using any tissue type for dural coverage and 2-layer primary closure of the skin.

Achieving the Optimal Aesthetic Benefit While Correcting Midface Deficiency: Utilizing A High Winged Le Fort I in Cleft and Craniofacial Patients.

ABSTRACT: Craniofacial anomalies are congenital disorders that affect the cranium and facial bones, with cleft lip and palate being the most common. These anomalies are often associated with abnormal development of pharyngeal arches and can result in the development of class III malocclusion and severe maxillary retrusion. Current treatment includes orthodontic decompensation and Le Fort I osteotomy to correct the maxillomandibular relationship. However, the traditional Le Fort I (LFI) advancement does not fully address the lack of skeletal volume in the midface. The high winged Le Fort I osteotomy (HWLFI) is an excellent surgical option for simultaneous correction of the midface deficiency and malocclusion while restoring optimal esthetic convexity. A retrospective chart review was conducted to include all cleft and craniofacial patients who underwent HWLFI advancement from 2002 to 2018. Patients had a minimum of 12 months of follow-up. Patient data and complications were reviewed. Standardized facial photographs were analyzed for esthetic improvement, occlusion, and beneficial salutary effects on the midface. Forty-three patients met the inclusion criteria. The mean age at surgery was 18.9 years. The mean follow-up was 32 months. Early complications included infection (9.3%) and temporary nerve paresthesia (2.3%). Late complications included infection (6.5%), wound dehiscence (4.3%), and painful hardware (2.3%). One patient (2.3 percent) had clinically significant relapse that required surgery. Postoperatively, patients demonstrated excellent midface projection and correction of the skeletal malocclusion. The HWLFI advancement significantly improves both the malocclusion and esthetic concerns of cleft and craniofacial patients by reestablishing maximal midfacial support. Important advantages of the HWLFI are avoidance of alloplastic implant use and extensive and potentially unstable surgical procedures that increase orbital volume.

"Longitudinal Experience Using Pedicled Buccal Fat Pad Flaps in Cleft Palatoplasty: Mitigating Velopharyngeal Insufficiency Risk and Severity".

BACKGROUND: Cleft palatoplasty commonly results in denuded maxillary bone in the lateral gutter(s) and a posterior void between oral and nasal closures. Bony exposure of the anterior palate subjects the maxilla to scarring and growth restriction, while scar contracture of the posterior void may result in velopharyngeal insufficiency (VPI) and fistula formation. Utilization of the buccal fat pad flap (BFPF) at the time of palatoplasty provides vascularized tissue over these critical areas, thereby reducing the rate of secondary surgery for speech and fistula revision. METHODS: A single-center, retrospective review identified patients who underwent palatoplasty with or without BFPF between 1995-2015. Data collected included cleft type, surgical technique, follow-up duration, and complications. Outcomes included rate of speech surgery and palatal fistula development. Veau phenotype index was computed on a scale of 2-4 as a weighted mean to reflect the frequency of cleft type (Veau II-IV) in BFPF and non-BFPF groups. RESULTS: Charts of 866 patients were reviewed; 212 met inclusion criteria. Of these, 101 received a BFPF. Mean follow-up duration was 11.4 years. Despite a selection bias for more severe clefts, the BFPF group had lower incidence of speech surgery (9.9% vs. 36.9%, p=0.0072). The BFPF group had more mild cases treatable with fat injection (7.9% vs. 2.7%, p=0.0346) and developed fewer fistulas (6.9% vs. 18.0%, p=0.0280). CONCLUSION: Despite the presence of more severe clefts, the BFPF group had a significantly lower rate of speech surgery. The BFPF is a valuable adjunct in primary palatoplasty, reducing VPI and fistula formation.

Keloid Intralesional Excision Reduces Recurrence: A Meta-analytic Study of the Available Literature on 608 Keloids.

Background: The objective of this meta-analysis was to examine the effectiveness of keloid intralesional excision (KILE) in preventing recurrence. Treatment of keloids using surgical excision alone leads to high rates of recurrence. To date, there are no widely accepted guidelines for keloid treatment, and a multitude of adjunctive therapies are used to reduce recurrence. Despite these efforts, recurrence remains high. In this study, we conducted a meta-analysis of the existing literature on KILE to determine its role in recurrence reduction. Methods: A literature review using PubMed, Scopus, and Web of Science databases was performed. Two authors independently evaluated studies for eligibility. Incidence of keloid recurrence was recorded, and a comprehensive meta-analysis was performed to assess the pooled keloid recurrence rate, as well as the effect of additional therapies. Results: Twenty-two studies evaluating intralesional excision of 608 keloids were included in the study. Average time to follow-up was 19.2 months (range 6-35 months). A meta-analysis of proportions was conducted, demonstrating a pooled recurrence rate of 13% (95% confidence interval, 9%-16%). There was no evidence that using therapies in addition to KILE had a significant effect on the overall pooled recurrence rate. Conclusions: A meta-analysis of 608 keloids shows that KILE is an effective technique in preventing keloid recurrence, with a pooled recurrence rate of 13% compared with previously reported rates of 45%-100% after complete excision. Although there are no standard guidelines for keloid treatment, our meta-analysis shows that KILE is promising in recurrence reduction.

Pindborg tumor in early childhood: a rare tumor in the youngest patient reported to date.

We report the case of a 5-year-old patient and provide recommendations for the care of pediatric patients diagnosed with this rare odontogenic tumor.

Weighing In on the Controversy: Preoperative Imaging in Unicoronal Craniosynostosis Leads to Strategic Changes in Surgical Care.

BACKGROUND: Clinical findings in children with unilateral coronal craniosynostosis are characteristic, and therefore clinicians have questioned the need for confirmatory imaging. Preoperative computed tomographic imaging is a powerful tool for diagnosing associated anomalies that can alter treatment management and surgical planning. The authors' aim was to determine whether and how routine preoperative imaging affected treatment management in unilateral coronal craniosynostosis patients within their institution. METHODS: A retrospective, single-center review of all patients who underwent cranial vault remodeling for unilateral coronal craniosynostosis between 2006 and 2014 was performed. Patient data included demographics, age at computed tomographic scan, age at surgery, results of the radiographic evaluation, and modification of treatment following radiologic examination. RESULTS: Of 194 patients diagnosed with single-suture craniosynostosis, 29 were diagnosed with unilateral coronal craniosynostosis. Additional radiographic anomalies were found in 19 unilateral coronal craniosynostosis patients (65.5 percent). These included severe deviation of the anterior superior sagittal sinus [n = 12 (41.4 percent)], Chiari I malformation [n = 1 (3.4 percent)], and benign external hydrocephalus [n = 2 (6.9 percent)]. The radiographic anomalies resulted in a change in management for 48.3 percent of patients. Specifically, alteration in frontal craniotomy design occurred in 12 patients (41.4 percent), and two patients (6.9 percent) required further radiographic studies. CONCLUSIONS: Although clinical findings in children with unilateral coronal craniosynostosis are prototypical, preoperative computed tomographic imaging is still of great consequence and continues to play an important role in surgical management. Preoperative imaging enabled surgeons to alter surgical management and avoid inadvertent complications such as damage to a deviated superior sagittal sinus. Imaging findings of Chiari malformation and hydrocephalus also permitted judicious follow-up. CLINICAL QUESTIONS/LEVEL OF EVIDENCE: Therapeutic, IV.

Management of Calcified Cephalohematoma of Infancy: The University of Michigan 25-Year Experience.

BACKGROUND: Cephalohematoma of infancy is the result of a subperiosteal blood collection that usually forms during birth-related trauma. A small proportion of cephalohematomas can calcify over time, causing a permanent calvarial deformity that is only correctable with surgery. The authors present a technique for the excision and reconstruction of calcified cephalohematoma and their management experience over the past 25 years. METHODS: All patients with a diagnosis of calcified cephalohematoma between 1994 and 2019 were identified. Patients were included if the diagnosis was confirmed by a pediatric plastic surgeon or a neurosurgeon. All patients underwent surgical evaluation followed by surgical intervention or observation. Patient demographics and potential risk factors for both surgical and nonsurgical groups were compared using chi-square or Fisher's exact test. Additional data were collected for the surgical cohort. RESULTS: Of 160 infants diagnosed with cephalohematoma, 72 met inclusion criteria. Thirty patients underwent surgical treatment. There was no significant difference in demographics, baseline characteristics, or potential risk factors between the operative and nonoperative groups. Mean age at the time of surgery was 8.6 months. Twenty-one surgical patients (70 percent) required inlay bone grafting. All surgery patients had improvement in calvarial shape. The main risk of surgery was blood loss requiring transfusion [eight patients (26.7 percent)]. Thirteen percent of patients experienced minor complications. CONCLUSIONS: This series of 72 children with calcified cephalohematomas, 30 of whom required surgical intervention, is one of the largest to date. The technique presented herein demonstrated excellent surgical outcomes by restoring normal cranial contours and was associated with a low complication profile.
