The Effectiveness of Facial Neuromuscular Retraining on Patients with Facial Nerve Dysfunction: A Mental Health and Quality of Life Analysis.

Background: Facial muscle dysfunction can have drastic psychosocial effects. Objectives: To evaluate the impacts of customized neuromuscular retraining on mental health, quality of life (QoL), facial muscle function, and synkinesis. Methods: Thirty patients with facial nerve dysfunction completed a course of neuromuscular retraining. Patients' mental health, QoL, facial muscle function, and synkinesis were evaluated using Patient Health Questionnaire (PHQ-9), Facial Clinimetric Evaluation (FaCE) scale, electronic, clinician-graded facial function scale (eFACE), and Synkinesis Assessment Questionnaire (SAQ) at the initial and final visits. Scores were compared before and after treatment. Results: Patients (n = 30) included had a mean age of 59.4 ± 13.4 years (range 32.3-82.8) and were mostly female (22/30, 73.3%). The most common etiology was Iatrogenic facial nerve paralysis (11/20, 36.7%). Most patients had postfacial paralysis synkinesis (15/30, 50%), while 10 had complete flaccid paralysis. The median house-Brackmann score was 2 (range 1-6). The mean duration of facial palsy was 39.5 ± 106.9 (range 1-576 months). The duration of follow-up after the initial treatment session was 5.5 months, including 10 sessions. After neuromuscular retraining median PHQ-9 scores improved from 5 (range 0-25) to 3 (range 0-20) (p = 0.002). Mean FaCE PROM scores increased from 47.7 ± 11.5 to 56.5 ± 8.8 (p = 0.001). The mean eFACE score increased from 55.8 ± 15.1 to 71.7 ± 13.6 (p < 0.001). Median SAQ score was lower at the final visit (34.6 ± 13.4) compared to the initial visit (47.7 ± 17.8; p < 0.001). Conclusion: Customized neuromuscular retraining may improve patient-reported mental health, QoL, and facial muscle function and reduce synkinesis in facial nerve dysfunction.

Recalcitrant Pyoderma Gangrenosum of the Face: A Case Report.

Pyoderma gangrenosum (PG) is a rare autoinflammatory neutrophilic dermatosis. The ulcerative subtype presents with a tender nodule or pustule that progresses into a painful, necrotic ulcer.New lesions arise after minor trauma in one-third of patients, a phenomenon termed "pathergy." We present a 62-year-old Caucasian female with primary sclerosing cholangitis, hepatic cirrhosis, chronic hepatitis B, and severe PG. At the initial presentation, she had lesions on her face and four extremities. She had severe full-thickness ulcerations on the bilateral cheeks and underwent incision and drainage with washout of bilateral maxillary abscesses, left sinus curettage, and wound debridement. She has required multiple hospitalizations for severe flares. Treatment with steroids was complicated by spinal compression fractures. Steroid-sparring agents were ineffective. Her lesions involved bilateral cheeks, temples, temporal scalp, and eyelids with oroantral fistulae. Her facial ulcerations included a large septal perforation causing saddle nose deformity and eradication of a branch of the left facial nerve causing incomplete eye closure. She underwent bilateral facial wound irrigation with antibiotic irrigation and wound debridement. Due to social factors, she has been lost to follow-up and a definitive etiology of her PG has not yet been elucidated. Although rare, PG should remain a consideration in patients with ulcerative lesions on the head and neck. Wound debridement is typically discouraged given the risk of pathergy, but there may be a role for surgical intervention in adequately immunosuppressed patients.

The Impact of the Post-Traumatic Facial Reconstruction on Postoperative Weight Loss.

Objectives: To identify risk factors and evaluate the impact of various facial fractures and reconstruction surgeries on postoperative weight change. Methods: Retrospective, monocentric study was performed at a tertiary care center. Medical history, type and mechanism of fracture, operative factors, and postoperative weights at follow-up appointments for 145 adult patients undergoing surgical repair for maxillofacial fractures were collected. Further information was obtained on postoperative diet and whether patients received maxillomandibular fixation (MMF). Univariate and multivariate analyses were utilized to evaluate effects of surgical reconstruction after facial trauma on postoperative weight loss. Results: Patients lost 3.2 ± 4.9 kg (95% confidence interval = 2.7-4.1, P < .0001) on average, with maximum loss between date of surgery and first follow-up. Univariate analysis demonstrated that intensive care unit admission (5.9 kg, SD 5.4, P = .001), nasogastric tube placement (5.1 kg, SD 4.6, P = .012), and MMF (4.4 kg, SD 5.4, P < .0001) were associated with more severe weight loss. Multivariate analyses showed that only MMF remained a significant risk factor for increased weight loss (avg. 6.0, standard error 1.93, t value 3.11, P = .0024). Conclusions: We report significant weight loss following facial trauma and reconstruction, which emphasizes the need to perform further studies on nutrition protocols for this patient population to optimize wound healing.

Minimization of facial synkinesis.

PURPOSE OF REVIEW: To summarize the treatment options available for the management of postparalytic facial synkinesis which include facial rehabilitation, chemodenervation, and a spectrum of surgical interventions. RECENT FINDINGS: Facial rehabilitation and botulinum toxin chemodenervation represent the foundation of facial synkinesis management, with specific treatment paradigms directed by individual patient needs. Evolving surgical approaches range from isolated selective myectomies or neurectomies to combination approaches which may incorporate various types of nerve transfer with gracilis free muscle transplantation. SUMMARY: Postparalytic facial synkinesis bears significant patient morbidity due to aesthetic and functional implications. Management strategies must balance patient goals with treatment risks and typically progress stepwise from the least to most invasive interventions. Emerging techniques reveal a convergence in approaches to facial reanimation and synkinesis mitigation.

Ergonomics in Otolaryngologic Surgery: A State of the Art Review.

OBJECTIVE: Otolaryngology is a surgical field with a high degree of ergonomic risk. The use of head-mounted lighting, loupe magnification, endoscopes, and microscopes is inherent to the field, coupled with repetitive fine motor movements in a constrained anatomic field as well as static, ergonomically unfavorable postures. We seek to review the otolaryngologic literature on ergonomics, including prevalence, severity, and interventions in decreasing work-related musculoskeletal pain. DATA SOURCES: Data were derived from clinical peer-reviewed primary literature as well as information provided by residency programs and presented at national and international meetings. REVIEW METHODS: A comprehensive review was performed by 3 independent reviewers utilizing an electronic database literature search through PubMed, Embase, and Cochrane Library. Search terms included combinations and variations of the following concepts: ergonomics, surgery, otolaryngology, work related musculoskeletal disorders, chronic cervical pain, musculoskeletal, posture, surveys, microsurgery, endoscopic surgery. Strict objective criteria for inclusion were not used due to the inherent heterogeneity in articles and lack of rigorous empirical evidence. CONCLUSIONS: Chronic musculoskeletal pain is prevalent among otolaryngologic surgeons, with many procedures producing high ergonomic risk. Most studies evaluating interventions to decrease ergonomic risks demonstrate promising results, but standardization in methods and outcome reporting is needed. IMPLICATIONS FOR PRACTICE: Literature shows that musculoskeletal pain begins in training, and there is a paucity of information related to ergonomic risk in otolaryngology residency curriculums. Work-related musculoskeletal disorders related to poor workplace ergonomics have the potential to limit career longevity and lead to physician burnout. Interventions to mitigate this risk are effective and tend to be well received by physicians.

Quantifying Aerosol Generation in Maxillofacial Trauma Repair Techniques.

Study Design: Cadaveric simulation study. Objective: The novel coronavirus (COVID-19), which can be transmitted via aerosolized viral particles, has directed focus on protection of healthcare workers during procedures involving the upper aerodigestive tract, including maxillofacial trauma repair. This study evaluates particle generation at different distances from open reduction and internal fixation (ORIF) of maxillofacial injuries in the intraoperative setting to reduce the risk of contracting airborne diseases such as COVID-19. Methods: Two cadaveric specimens in a simulated operating room underwent ORIF of midface and mandible fractures via intraoral incisions as well as maxillomandibular fixation (MMF) using hybrid arch bars. ORIF was performed with both self-drilling screws and with the use of a power drill for creating guide holes. Real-time aerosol concentration was measured throughout each procedure using 3 particle counters placed 0.45, 1.68, and 3.81 m (1.5, 5.5, and 12.5 feet, respectively) from the operative site. Results: There was a significant decrease in particle concentration in all procedures at 1.68 m compared to 0.45 m, but only 2 of the 5 procedures showed further significant decrease in particle concentration when going from 1.68 to 3.81 m from the operative site. There was significantly less particle concentration generated at all distances when using self-drilling techniques compared to power drilling for ORIF. Conclusions: Consideration of using self-drilling screwing techniques as well as maintaining physical distancing protocols may decrease risk of transmission of airborne diseases such as COVID-19 while in the intraoperative setting.

Analysis of Environmental Exposures for Nonsyndromic Cleft Lip and/or Palate: A Case-Control Study.

Background: Orofacial cleft is among the most common developmental malformations in humans. This study aimed to identify the relationship between environmental factors and nonsyndromic cleft lip and/or palate (NSCL/P) in Northwest China. Methods: This case-control study was conducted in Gansu Province, China over two years (Jan. 1, 2017-Jan. 1, 2019). Overall, 600 NSCL/P cases and 660 normal control cases were finally enrolled in the current study. Data were collected by conducting face-to-face interviews with both parents of each case. Results: Univariate (χ2) analysis revealed 22 factors as being significantly associated with NSCL/P. Multivariate (stepwise logistic regression) analysis identified that 14 factors had statistically significant association with NSCL/P. Male gender (OR=0.789), paternal age at childbirth of 25-29 yr (OR=0.690), and folic acid supplement (OR=0.197) were found to be protective factors against NSCL/P. On the other hand, blood A-type, multiple births, positive family history of NSCLP (OR=6.660), parental consanguinity (OR=6.107), positive abortion history, high or low maternal childbearing age, and maternal passive smoking (OR=4.349), malnutrition (OR=4.431), infections, and drug use (OR=2.188) during early gestation were significant risk factors for NSCL/P. Conclusion: Parental age at childbirth of 25-29 yr, and folic acid supplement can reduce the risk of NSCL/P. By contrast, maternal passive smoking, infections, and drug use during early gestation period, and multiple births, parental consanguinity, positive family history, and maternal abortion history can increase the risk of NSCL/P. Identification of risk factors is essential in minimizing the incidence of NSCL/P in a particular population.

Pediatric Mandible Fractures: Mechanism, Pattern of Injury, Fracture Characteristics, and Management by Age.

Background: Development of the craniofacial skeleton and different mechanisms of injury warrant different treatment paradigms for younger children versus those at skeletal maturity. Objective: To characterize the mechanism, fracture patterns, and management of mandible fractures across the pediatric age spectrum. Methods: A 10-year retrospective review of <18-year-old children with mandible fractures at a level 1 trauma center. Characteristics were compared by age subgroup analysis. Results: Of 220 patients meeting inclusion criteria, motor vehicle collision (n = 53, 40.8%), falls (n = 48, 36.9%), and assault (n = 19, 14.6%) were the most common mechanisms with more falls in younger children and more injury by assault in teenagers. Condylar fractures were most common in the 0- to <9-year-old children (n = 27, 38.4%); angle/ramus fractures (56, 62.6%) were most common in 15- to <18-year-old children (p < 0.001). Nonsurgical management was associated with younger age (p < 0.001). Fourteen of 125 patients (8.0%) undergoing surgical intervention experienced complications. Being uninsured was associated with shorter median (interquartile range) follow-up of 5.6 (1.4-10.7) weeks, compared with private [11.9 (4.3-49.0) weeks] and public insurance [11.7 (3.7-218.0) weeks] (p < 0.001). Conclusion: The mechanism, fracture sites, and treatment differed by age with the youngest frequently managed nonoperatively and teenagers treated with adult algorithms. Complications were rare overall within 6-12 weeks after injury, with or without surgical management.

Management of Posttraumatic Enophthalmos Including Complex Secondary Deficits.

Posttraumatic enophthalmos (PE) arises when the ocular globe is displaced posteriorly and inferiorly in the orbital cavity due to a mismatch in orbital volume and orbital content. This most commonly happens after orbital fractures. The resulting disruptions to aesthetic form and ocular functions often necessitate surgical correction for reconstruction and restoration. The purpose of surgical management of PE is to reconstruct orbital shape and volume as well as to restore any herniated orbital content. This can be particularly challenging in cases involving large defects that require complex orbital reconstruction. Recent advancements in computer-aided surgery have introduced innovative and important tools to assist surgeons with these difficult cases. The ability to create customized, patient-specific implants can facilitate reconstruction involving complicated anatomy. Additionally, intraoperative imaging and intraoperative navigation can serve as useful guides for surgeons to more accurately place implants, especially in cases with limited visualization, in order to achieve optimal outcomes.

Three-Dimensional Printing in Cleft Care: A Systematic Review.

OBJECTIVE: To determine the current applications of 3-dimensional (3D) printing in the care of patients with cleft lip and palate. We also reviewed 3D printing limitations, financial analysis, and future implications. DESIGN: Retrospective systematic review. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used by 3 independent reviewers. Articles were identified from Cochrane library, Ovid Medline, and Embase. Search terms included 3D printing, 3 dimensional printing, additive manufacturing, rapid prototyping, cleft lip, and cleft palate. Exclusion criteria included articles not in English, animal studies, reviews without original data, oral presentations, abstracts, opinion pieces, and articles without relevance to 3D printing or cleft lip and palate. MAIN OUTCOME MEASURES: Primary outcome measure was the purpose of 3D printing in the care of patients with cleft lip and palate. Secondary outcome measures were cost analysis and clinical outcomes. RESULTS: Eight-four articles were identified, and 39 met inclusion/exclusion criteria. Eleven studies used 3D printing models for nasoalveolar molding. Patient-specific implants were developed via 3D printing in 6 articles. Surgical planning was conducted via 3D printing in 8 studies. Eight articles utilized 3D printing for anatomic models/educational purposes. 3-Dimensional printed models were used for surgical simulation/training in 6 articles. Bioprinting was utilized in 4 studies. Secondary outcome of cost was addressed in 8 articles. CONCLUSION: 3-Dimensional printing for the care of patients with cleft lip and palate has several applications. Potential advantages of utilizing this technology are demonstrated; however, literature is largely descriptive in nature with few clinical outcome measures. Future direction should be aimed at standardized reporting to include clinical outcomes, cost, material, printing method, and results.

Alloplastic Facial Implants.

As the face ages, there is thinning of the epidermis, volume loss and rearrangement of the soft tissues, and malabsorption of the skeletal framework. It is essential to have a thorough understanding of the aging process for successful facial augmentation and rejuvenation. Alloplastic implants can be used to provide a long-lasting solution for augmentation of skeletal deficiencies, restoration of facial irregularities, and rejuvenation of the face. In this study, we describe the ideal implant characteristics along with the advantages and disadvantages of various implant materials. We also present techniques in nasal and premaxillary augmentation, midface augmentation, mandibular augmentation, and lip augmentation. Additionally, computer-aided design and manufacturing as well as bioprinting are emerging technologies with growing applications in facial plastic and reconstructive surgery. We discuss their role in the creation of patient-specific custom implants. The overall goal of facial rejuvenation is to address multiple aspects of the facial aging process including deficiencies in the skin, soft tissues, and skeletal framework. The use of alloplastic implants alone or synergistically with additional surgical procedures can restore a wide range of anatomical deficits that occur with age.

Predicting complications of pediatric temporal bone fractures.

OBJECTIVE: Our aim is to characterize complications of pediatric temporal bone fractures and identify predictive risk factors associated with fracture complications. METHODS: A retrospective review was conducted of all temporal bone fractures diagnosed in children (age less than or equal to 18 years) from a single academic institution between 2003 and 2017. Demographics, mechanism of injury, fracture characteristics, computed tomography evaluation and follow-up duration were recorded on each patient. Outcomes measured include facial nerve injury (FNI), cerebrospinal fluid (CSF) leak, sensorineural hearing loss (SNHL), and conductive hearing loss (CHL). RESULTS: One-hundred-seventeen patients with 129 temporal bone fractures were included in the study. Most fractures were otic capsule sparing (OCS) (96%, n = 124) and longitudinal (71%, n = 91). Otic capsule violating (OCV) fractures were associated with higher CSF leak rates (20% versus 2%, p = 0.14) and FNI rates (60% versus 5%, p = 0.002) compared to OCS fractures. Audiograms were available in 37 patients (34%). Patients with Glasgow coma scale (GCS) consistent with a mild traumatic brain injury (TBI) (GCS > 13) had significantly fewer complications (FNI and CSF leaks) compared to the group with moderate and severe TBI (GCS < 13), 5% versus 23% (p = 0.03). CONCLUSIONS: Higher complication rates are seen with OCV fractures and transverse fractures. Moderate and severe TBI as measured by GCS is predictive of FNI and CSF complications in pediatric temporal bone fractures.

A Guide to Facial Trauma Triage and Precautions in the COVID-19 Pandemic.

COVID-19 is an emerging viral illness that has rapidly transmitted throughout the world. Its impact on society and the health care system has compelled hospitals to quickly adapt and innovate as new information about the disease is uncovered. During this pandemic, essential medical and surgical services must be carried out while minimizing the risk of disease transmission to health care workers. There is an elevated risk of COVID-19 viral transmission to health care workers during surgical procedures of the head and neck due to potential aerosolization of viral particles from the oral cavity/naso-oropharynx mucosa. Thus, patients with facial fractures pose unique challenges to the variety of injuries and special considerations, including triaging injuries and protective measures against infection. The proximity to the oral cavity/naso-oropharyngeal mucosa, and potential for aerosolization of secretions containing viral particles during surgical procedures make most patients undergoing operative interventions for facial fractures high risk for COVID-19 transmission. Our proposed algorithm aims to balance patient care with patient/medical personnel protection as well as judicious health care utilization. It stratifies facial trauma procedures by urgency and assigns a recommended level of personal protective equipment, extreme or enhanced, incorporating current best practices and existing data on viral transmission. As this pandemic continues to evolve and more information is obtained, the protocol can be further refined and individualized to each institution.

Multi-Institutional Regional Otolaryngology Bootcamp.

INTRODUCTION: In order to increase junior resident physician proficiency and improve patient safety, simulation-based procedural training courses, or bootcamps, have been become an emerging educational tool. OBJECTIVES: To compare pre- and post-course confidence levels and to assess station efficacy after completion of our single day bootcamp. METHODS: We developed the University of California (UC) Davis otolaryngology bootcamp, a single day course including six cadaveric task trainer stations and four simulations. The six task trainer stations included (1) Epistaxis, (2) Cricothyrotomy/tracheostomy, (3) Peritonsillar abscess/auricular hematoma, (4) Nasal bone reduction/zygoma reduction/lateral canthotomy/canalicular trauma and probing, (5) Local nerve blocks, and (6) Soft tissue reconstruction. The simulations comprised of airway fire during tracheostomy, pediatric respiratory code during airway evaluation, dislodged pediatric tracheostomy tube in the ICU, and angioedema in the emergency department with inability to intubate or ventilate. Junior residents from multiple locoregional institutions were recruited to participate. Pre- and post-course Likert surveys assessing participant confidence and station efficacy were collected and analyzed. RESULTS: There was a statistically significant increase in resident confidence levels for all task trainer stations. All stations had a station efficacy Likert score average of 4 "very effective" or 5 "most effective." CONCLUSION: A multi-institutional, locoregional, simulation-based bootcamp can be a valuable adjunct to junior resident training. It can promote camaraderie, pool limited resources, and may be cost-effective.

Assessment of the Learning Curve for Virtual Surgical Planning in Orbital Fractures.

Virtual surgical planning (VSP) is becoming more widely used in maxillofacial reconstruction and can be surgeon-based or industry-based. Surgeon-based models require software training but allow surgeon autonomy. We evaluate the learning curve for VSP through a prospective cohort study in which planning times and accuracy of 7 otolaryngology residents with no prior VSP experience were compared to that of a proficient user after a single training protocol and 6 planning sessions for orbital fractures. The average planning time for the first session was 21 minutes 41 seconds ± 6 minutes 11 seconds with an average maximum deviation of 2.5 ± 0.8 mm in the lateral orbit and 2.3 ± 0.6 mm in the superior orbit. The average planning time for the last session was 13 minutes 5 seconds ± 10 minutes and 7 seconds with an average maximum deviation of 1.4 ± 0.5 mm in the lateral orbit and 1.3 ± 0.4 mm in the superior orbit. Novice users reduced planning time by 40% and decreased maximum deviation of plans by 44% and 43% in the lateral and superior orbits, respectively, approaching that of the proficient user. Virtual surgical planning has a quick learning curve and may be incorporated into surgical training.

Assessment of Tracheostomy and Laryngectomy Knowledge among Non-Otolaryngology Physicians.

OBJECTIVE: Identify knowledge deficits about alternate airways (AAs) (tracheostomy and laryngectomy) among physicians across multiple specialties a tertiary institution and to assess the impact of an educational lecture on improving deficits. METHODS: Study Design: Cross-sectional assessment. Setting: Academic medical center. Subjects and Methods: An anonymous 10-item, multiple choice assessment was given to physicians at a tertiary care center in the departments of Otolaryngology, Emergency Medicine, Family Medicine, General Surgery, Internal Medicine, and Pediatrics. An educational lecture on AAs was presented. Scores between a pre-lecture and a 3-month post-lecture assessment were compared. Data was analyzed using ANOVA and chi-squared analysis. RESULTS: Otolaryngology physicians scored an average of 97.8%, while non-otolaryngology physicians scored 58.3% (P < .05). Non-otolaryngology surgical physicians scored 68.4% while non-surgical physicians were lower at 55.1% (P < .0001). Comparing pre-lecture to post-lecture scores, all non-otolaryngology physicians improved their scores significantly from 58.3% to 86.5% (P < .005). Non-surgical physicians had significant improvement after the instructional lecture, closing the score gap with surgical physicians for the post-lecture assessment. DISCUSSION: The care of patients with AAs requires an understanding of their basic principles. Our findings identify significant knowledge deficits among non-otolaryngologists. Through an instructional lecture, we demonstrated improvement in knowledge among non-otolaryngology physicians and durability of the knowledge after 3 months. CONCLUSIONS: Through an instructional lecture, we found tracheostomy and laryngectomy knowledge deficits can be identified and improved upon. Periodic reinforcement of basic principles for non-otolaryngology physicians may be a promising strategy to ensure the proper care of patients with AAs.
