Primary Ear Reconstruction Using Cadaveric Costal Cartilage.

OBJECTIVE: Allogeneic cadaveric costal cartilage is commonly used for grafts in nasal reconstruction surgery; however, limited information exists on its use in total ear reconstruction for microtia. In this case series, we describe the novel use of cadaveric cartilage for auricular framework construction in ear reconstruction and review preliminary histologic findings. METHODS: Patients requiring primary complete reconstruction of the auricle from August 2020 to December 2021 were eligible and underwent ear reconstruction using cadaveric costal cartilage. Patients were evaluated for surgical site infection, skin necrosis, cartilage resorption, and cartilage exposure during regular follow-up visits. Two cartilage samples were taken after 2 separate second-stage surgeries done 52 weeks after first-stage reconstruction. These samples were stained with hematoxylin and eosin as well as safranin-O and examined under light microscopy. RESULTS: A total of 12 ear reconstruction procedures using cadaveric costal cartilage were performed across 11 patients; 10 of 12 ears had type III microtia and 2 of 12 ears had type IV microtia. Patients ranged from 4 to 25 years old at the time of surgery, with an average age of 10.7 years. Follow-up time ranged from 1.6 to 25.4 months, with a mean follow-up time of 11.2 months. No patients experienced any visibly significant cartilage warping. Two patients experienced minor construct exposure, which were successfully salvaged. Two patients experienced surgical site infections, one lead to resorption requiring framework replacement. Preliminary histologic analysis of the 2 samples taken 1 year after implantation showed viable chondrocytes with no evidence of immunologic rejection or any local inflammation or host foreign body response. CONCLUSIONS: Cadaveric costal cartilage serves as a viable alternative to autologous cartilage and other alloplastic biomaterials for construction of auricular frameworks in primary microtia reconstruction. Resorption secondary to infection and construct exposure remain potential risks. Longer follow-up times and a larger sample size are needed for assessment of long-term efficacy.

Feasible Removal of Facial Hemangiomas Under Local Anesthesia in Young Children.

BACKGROUND: Facial Hemangiomas are often recommended to be removed exclusively in the operating room under general anesthesia, especially for children under the age of 4. Assumed parental and patient anxiety and possible blood loss pushes surgeons away from attempting excision under local anesthesia. METHODS: A review was conducted to assess the outcomes of children who underwent excision of facial hemangiomas under local anesthesia alone by 1 plastic surgeon with a minimum of 3 months follow-up. Complications and hemangioma recurrence were recorded. A survey was given 3 to 6 months after treatment to assess parental satisfaction, anxiety, and thought process about anesthesia. RESULTS: Eighteen children (9 males and 9 females) underwent in-office excision between 2020 and 2021. The mean age of this cohort was 12 months ( ranging 2-52 m). The average facial hemangioma size was 2.088 cm (ranging 1.0-3.2 cm). Ten patients experienced complete resolution (56%) at 12-month follow-up. There were no hospitalizations or cases of significant (>10 mL) blood loss, infection, dehiscence, hematoma, or scar hypertrophy. The average level of parental anxiety before the procedure was 3.3/10, and 1.6/10 after the procedure. Total 13/14 parents gave 4/4 ratings for satisfaction with the quality of care, team responsiveness, pain management, and management of expectations. CONCLUSIONS: Facial hemangioma removal under local anesthesia alone is a safe and feasible alternative treatment method for patients younger than 4 years of age.

Inferiorly Directed Posterior Cranial Vault Distraction for Treatment of Chiari Malformations.

OBJECTIVE: The authors present a case series of patients with Chiari I malformations treated with distraction osteogenesis of the posterior cranial vault, utilizing a vertical distraction vector for appropriate cranial vault expansion while mitigating the risks of scaphocephaly and cerebellar ptosis. PATIENTS AND METHODS: Patients with syndromic and nonsyndromic Chiari I malformations treated with vertical-vector distraction osteogenesis of the posterior cranial vault were identified from 2008 to 2014. Demographics, preoperative and postoperative clinical symptoms, and perioperative details were assessed. Long-term esthetic outcomes, complications, and symptomatic improvement were evaluated in conjunction with neurosurgery. RESULTS: Nine patients were identified. Five had known syndromes, 2 likely had unidentified syndromes, and 2 were nonsyndromic. Seven had prior Chiari-related surgeries. Most presented with hydrocephalus, motor symptoms, and developmental delay. Operatively, 2 to 3 internal distraction fixators were applied such that the vector of distraction was along a cephalad-caudad axis. Devices were activated on postoperative day 5 and distracted 1 mm per day. Three postoperative complications were found within the first 3 months which included a dislodged distraction arm, a device extrusion, and a local cellulitis. No complications affected the clinical outcome. Radiographic follow-up showed good bone formation, decompression of the posterior fossa, improved cerebrospinal fluid flow, and no cerebellar ptosis. Neurological surveillance showed improvement in intracranial pressure, hydrocephalus, motor symptoms, and behavioral problems. CONCLUSION: The authors have presented 9 patients with Chiari I malformations treated with distraction osteogenesis, along with a novel technique to safely and effectively expand the posterior fossa while minimizing the risk of cerebellar ptosis. LEVEL OF EVIDENCE: Level II (prognostic/risk studies).

Auricular Framework Construction Using Cadaveric Costal Cartilage in Type III Microtia: Preliminary Results.

PURPOSE: Non/minimally irradiated Cadaveric Costal Cartilage (NCCC) is commonly used for grafts in nasal reconstruction; however, no information exists on its use in total ear reconstruction for type III microtia. In this case series we describe preliminary results from the novel use of NCCC for auricular framework construction in 7 ear reconstructions. METHODS: Patients requiring total ear reconstruction from August 2020 to October 2021 were eligible and underwent ear reconstruction using NCCC from MTF Biologics (Edison, NJ). Patients were evaluated for surgical site infection, skin necrosis, cartilage exposure, warping, and resorption during regular follow up visits. RESULTS: Seven ears were reconstructed using NCCC across 5 patients with type III microtia. Patients ranged from 5 to 51 years old at the time of surgery. Follow up time ranged from 12 to 78 weeks (mean: 46 wk). No patients experienced surgical site infections or significant cartilage resorption. All procedures were done outpatient, total time under anesthesia was <90 minutes in 5/7 cases and postoperative narcotics for pain management were not needed in 5/7 cases. Complications included minor skin necrosis that was repaired via primary closure, construct exposure in the immediate postoperative period, which was successfully salvaged with a local flap, and explantation of one construct after reconstruction for a complicated revision surgery involving a previous temporoparietal fascial flap. CONCLUSION: NCCC serves as an immediately available alternative to alloplastic and autologous materials for construction of auricular frameworks during ear reconstruction. Longer follow up times and a larger sample size will further elucidate long-term efficacy.

Office-Based Pediatric Otoplasty Under Local Anesthesia.

BACKGROUND: Many parents seek otoplasty for their school age children but fear having to undergo general anesthesia (GA). In our experience, otoplasty can safely be performed in an office-based setting under local anesthesia (LA). There is a gap in the literature regarding pediatric otoplasty under LA. METHODS: All children aged 5 to 10 who underwent otoplasty between 2017 and 2021 were included in a retrospective review. Demographics, operative techniques, complications, recurrences, and reoperation rates were collected. Surveys were provided 3 months after treatment to assess parental satisfaction and anxiety. Results were compared between patients who received otoplasty under GA and LA. RESULTS: A total of 13 patients (6 male, 7 female), with a mean age of 7 years (ranging 5-10) underwent otoplasty under LA. Tweleve children (6 male, 6 female), with a mean age of 5 years (ranging 4-7) underwent otoplasty under GA. The only complications seen were 3 minor conchal bowl hematomas that were aspirated, each retrieving <1 mL of blood; no revisions were necessary. The LA subgroup was more likely to repeat otoplasty under identical conditions ( P =0.025). Postoperatively, mean parental anxiety scores between the LA and GA subgroups were significantly different (1.4±1.1 versus 4.8±2.7, P =0.0005). Lastly, the mean satisfaction scores between the LA and GA subgroups were marginally different (3.83±0.58 versus 3.17±1.03, P =0.063). CONCLUSION: Pediatric otoplasty under LA is a safe and feasible operation for patients between 5 and 10 years of age.

Nonsurgical Correction of Congenital Ear Deformities: The Relationship Between Age of Presentation and Regression.

PURPOSE: After 3 weeks of age, studies show ear molding to be unsuccessful due to increased regression rates. Studies have not differentiated success rates based on regression severity; partial regressions may be deemed successful and satisfactory by parents. We examined successful ear molding at different ages of presentation by measuring regression severity and parental satisfaction. METHODS: Patients who presented to [blinded for review] for ear molding from January 2017 to October 2018 were eligible for inclusion. Molds were applied on the initial visit and monitored biweekly. Treatment length was based on age, deformity type, and severity. One month after treatment completion, parents completed a satisfaction survey where they assessed regression on a 3-point severity scale. RESULTS: A total of 165 patients were included in this study. Sixty-seven were younger than 3 weeks of age and had an overall correction rate of 95%. The complete correction rate was 80% and only 5% saw complete regression. In the remaining 98, the overall correction rate was 94%, with a 63% complete correction rate. Only 6% saw complete regression. There was no statistical significance in parental satisfaction, perceived improvement, or likelihood to recommend ear molding between age groups. CONCLUSIONS: Regression rates are higher in children older than 3 weeks although not statistically significant. Most regressions were partial and ear molding still significantly corrected most deformities. We suggest that ear molding be offered past 3 weeks of age, with maximum age being dependent on deformity type, as it still leads to high parental satisfaction.

Multiprocedural Facial Feminization Surgery: A Review of Complications in a Cohort of 31 Patients.

OBJECTIVE: Facial feminization surgery (FFS) is instrumental in gender affirmation for transgender patients. Multiprocedural FFS, the combination of multiple facial feminization procedures across multiple depths and planes during one surgery, crosses sterile and nonsterile planes in the oropharynx, nose, and frontal sinus. A closer look at the prevention and management of resulting complications of such reconstruction is necessary. METHODS: We performed a retrospective review of patient demographics, operative variables, and postoperative complications on 31 FFS patients. Patients who underwent FFS between January 2020 and June 2021 were eligible for inclusion. Associations between prevention methods, procedure type, and complications were assessed by the Fisher exact test. The main effect of patient age and number of procedures on complication rate was assessed via the nonparametric Kruskal-Wallis test. RESULTS: A total of 31 patients, with a mean age of 37 years (range: 19-65 y, SD: 13.3 y), underwent 257 procedures. Patients underwent a mean of 8 procedures (SD: 2.2) lasting 3.5 to 6 hours (mean: 5.0 h, SD: 0.9 h). Overall, 68% of patients experienced no complications. Six patients experienced a postoperative infection; 4 of these patients required return for a washout. Preventative measures implemented include: preoperative dental check, intraoperative antibiotic irrigation, locking sutures, and postoperative antibiotics. After measures were implemented, there were no further procedure-related infections recorded. CONCLUSIONS: Patients do not suffer from major complications after multiprocedural FFS. Factors such as age, irrigation method, and dental history may be important variables affecting FFS outcomes.

The Use of the Three-Dimensional Printed Polyether Ether Ketone Implant in Secondary Craniosynostosis Revision.

BACKGROUND: Skull deformities may be seen in patients years after craniosynostosis correction. These deformities cause psychosocial distress in affected patients. In this series, the authors describe the use of patient specific polyether ether ketone (PEEK) implants for correction of skull deformities after cranial vault remodeling for craniosynostosis. METHODS: A chart review was conducted for 3 revision procedures performed by 1 plastic surgeon in collaboration with 1 neurosurgeon, both affiliated with Northwell Health. Preoperative computed tomography scans were used to design three-dimensional (3D) printed PEEK implants manufactured by KLS Martin. Implants were used to correct frontal and orbital asymmetry and skull deformities in each patient. Outcomes were assessed at 1 week, 1 month, and 3 months post-operation. RESULTS: Two males and 1 female, ages 13, 17, and 19, underwent revision cranioplasty or orbital rim reconstruction using a custom, single piece 3D printed PEEK implant. All 3 patients underwent cranial vault remodeling in infancy; 1 was treated for coronal craniosynostosis and 2 were treated for metopic craniosynostosis. Revision cranioplasty operative times were 90, 105, and 147 minutes, with estimated blood loss of 45 mL, 75 mL, and 150 mL, respectively. One patient went home on post op day 1 and 2 patients went home on post op day 2. All patients had an immediate improvement in structural integrity and cranial contour, and all patients were pleased with their aesthetic results. CONCLUSIONS: Custom 3D printed PEEK implants offer a single piece solution in revision cranioplasty surgery to correct skull deformities after cranial vault remodeling for craniosynostosis.

Virtual Events in the Era of COVID-19: Perspectives From a Virtual Interdisciplinary Wound Care Symposium.

BACKGROUND: The coronavirus disease-19 pandemic has created changes in the way medicine is practiced. The move to virtual conferencing to avoid mass gatherings is a significant change to how health care professionals meet, discuss current trends, and share research. METHODS: Data from exit polls conducted after annual wound care symposiums were reviewed. Physicians, nurses, podiatrists, and other health care professionals attended. Respondents were asked to comment and reflect on their experiences of attending a virtual conference. RESULTS: Over 60% of all (N = 283) respondents stated the virtual conference was better than or on par with a live event. Many respondents had attended this live event in person in previous years. Of all respondents, 83% stated that they planned to access conference materials for the 30 days they remained posted after the event. More than 50% of respondents stated they favored the ability to communicate effectively with colleagues via the instant messaging feature offered by the conference. Approximately 80% of respondents stated that they would like to attend this and other conferences virtually in the future. CONCLUSIONS: The shift from in-person to virtual conferences has the potential to remain a significant method of attending health care conferences. Conference organizers are encouraged to consider how they can implement virtual components, including postconference access to materials, to enhance the conference experience. Additional work needs to be done to understand the impact of the virtual format on knowledge retention.
