Facial Nerve Pathology in Children.

Facial nerve pathology in children has devastating functional and psychosocial consequences. Facial palsy occurs less commonly in children than adults with a greater proportion caused by congenital causes. Most pediatric patients have normal life expectancy and few comorbidities and dynamic restoration of facial expression is prioritized. This article will focus on the unique aspects of care for facial palsy in the pediatric population.

Management of facial nerve trauma.

PURPOSE OF REVIEW: To present the current literature on management of facial nerve disorder secondary to trauma, with a focus on the utility of electrodiagnostic testing in this setting. RECENT FINDINGS: Patients with facial palsy related to temporal bone fractures should be started on high-dose corticosteroids as early as possible. Recent literature on the benefit of surgical intervention in the setting of temporal bone fracture is mixed. Some studies support early surgical decompression whereas others have found no benefit compared with conservative treatment. SUMMARY: The management of facial nerve trauma is based on location and extent of injury. Extratemporal trauma and transected nerve should be treated with surgical exploration and tension-free coaptation ideally within 72 h. There are no guidelines for intratemporal facial nerve trauma. Surgical decompression compared with medical management is debated in the literature without consensus and more large studies are needed.

Commentary on: "Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization" by Brown et al.

We present a complementary report of a 38-year-old XY intersex female with frontal mucopyocele developing 5 years after frontal setback for gender-affirming surgery to supplement recent report by Brown et al: Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization by Brown et al.

Total lower lip reconstruction: a review of recent advances.

PURPOSE OF REVIEW: This review describes the fundamental principles and recent advances in the reconstruction of total lower lip defects to restore peri-oral aesthetic and function. RECENT FINDINGS: Modifications to the Abbe flap and visor flap have recently been described. Recent advances to free flap techniques have focused on dynamic restoration of lower lip sling function after reconstruction. This involves the transfer of innervated or noninnervated muscle tissue to reconstruct the lower lip to restore the sphincter function of the lips. SUMMARY: The reconstructive goals for a full thickness lower lip defect are to restore a functional oral sphincter, replace mucosal and external skin, and maintain a functional size of the oral aperture. Local flap reconstruction of sub-total lower lip defects is possible, but use of local flaps for total lip reconstruction often leads to microstomia. Several static and dynamic free tissue transfer options exist for lower lip reconstruction and have been summarized in this review.

Rhinoplasty: Considerations for Patients with Facial Paralysis.

Nasal obstruction is a common sequela of flaccid facial paralysis but one that is often underaddressed surgically. Weakness of nasal musculature on the paralyzed side of the face leads to nasal valve narrowing through loss of static and dynamic nasal side wall tone as well as inferomedial displacement of the alar base. Standard rhinoplasty techniques such as alar batten grafts or flaring sutures may be used to support the nasal side wall in facial paralysis. However, to address the inferomedial alar displacement, suspension techniques are often required. Suture resuspension and fascia lata resuspension techniques are described, with modifications to each to improve longevity of the suspension.

Pediatric Nasal and Septal Fractures.

Pediatric nasal bone and septal fractures represent a large number of craniofacial injuries in children each year. Due to their differences in anatomy and potential for growth and development, the management of these injuries varies slightly from that of the adult population. As with most pediatric fractures, there is a bias toward less-invasive management to limit disruption to future growth. Often this includes closed reduction and splinting in the acute setting followed by open septorhinoplasty at skeletal maturity as needed. The overall goal of treatment is to restore the nose to its preinjury shape, structure, and function.

Ophthalmologic Outcomes in Zygomaticomaxillary Fracture Repair With and Without Orbital Floor Repair.

Introduction: Orbital floor (OF) fractures accompany all zygomaticomaxillary complex (ZMC) fractures, but guidelines for repair of OF fractures in this setting are unclear. Objectives: To compare ophthalmologic outcomes of ZMC repair with and without concurrent OF repair. Methods: We retrospectively reviewed patients undergoing ZMC fracture repair with and without OF repair between 2016 and 2018. Patients were reviewed for demographics, preinjury characteristics, and ophthalmologic outcomes. Results: Of 61 total patients, 32 underwent concomitant OF repair while the remaining 29 underwent ZMC repair alone. The OF repair group had increased OF fracture size, displacement in the coronal plane, and malar eminence displacement (p < 0.05). Eight patients in the OF repair group had postoperative diplopia compared with no patients in the group without OF repair (p < 0.05). Conclusion: Retrospective analysis of ZMC fracture repair without and with OF repair did not reveal a significant difference in short-term ophthalmologic outcomes while controlling for fracture size.

Threading the Needle: A Case of Periorbital Gold Threading.

While a rare periorbital finding, the aesthetic practice of gold threading is increasingly identified in Western care setting and may be misidentified as the practice of inserting charm needles (susuk). The authors present a unique case of gold threading discovered incidentally during workup of chronic sinusitis and report a rarely seen delayed local site reaction. The practice of gold threading and mimickers including the practice of inserting charm needles (susuk) are reviewed with emphasis on clinical and radiographic differentiation by oculoplastic surgeons.

Breaking the mold: a case of recalcitrant eyelid subconjunctival infection by Exophilia Phaeomuriformis.

While a rare ophthalmic pathogen, infections from Exophilia spp. are increasingly identified and have been associated with catastrophic vision loss. In this case report we present a previously undescribed manifestation of the melanin-producing fungus Exophilia Phaeomuriformis to the lower eyelid, establish an effective treatment, and review related cases. Previous cases of ophthalmic E. Phaeomuriformis were confined to the cornea and included iatrogenic tissue trauma. This case shares neither associations however includes a remote SJS history that likely led to changes in conjunctival tissue integrity. Previous cases of Exophilia spp. infecting the eyelid both included surgical source control and adjuvant antibiotic. In this case, topical therapy was deferred due to SJS-related ocular cicatricial disease. Fortunately, a full resolution was achieved with surgical resection and oral antifungal treatment.

The Effect of COVID-19 Shelter-in-Place Orders on Pediatric Craniofacial Trauma.

Objectives: To investigate the impacts of the shelter-in-place orders on the injury patterns among children with craniofacial trauma. Materials and Methods: Pediatric (<18 years old) craniofacial trauma cases presenting to a regional level I trauma center 1 year before and after the initiation of Washington's shelter-in-place order were retrospectively reviewed. Demographic and injury-related variables were recorded, and bivariate and logistic regression analyses were computed. Results: One hundred nineteen children were evaluated over 2-year period (46 pre- and 73 post-shelter-in-place and were comparable in age, gender, and ethnicity (p ≥ 0.17)). The distribution of injury mechanisms between pre- and post-shelter-in-place were significantly different (p = 0.02), with the largest proportional increase in falls (10.5%) and had higher rates of associated brain injury (p ≤ 0.02). After adjusting for effect modifiers and confounders, children presenting during the post-shelter-in-place period were more likely to have associated brain injuries (odds ratio 3.4, 95% confidence interval: 1.11-10.6, p = 0.03). Conclusions: Among pediatric craniofacial injury cases, the shelter-in-place order was associated with a higher likelihood of brain injury and significant changes in injury mechanisms, with a higher proportion of falls.

Nuances of Septal Deviation Repair.

Septoplasty is one of the most common procedures performed by facial plastic surgeons. Surgical decision-making surrounding septal deviation repair centers around the location of deviation and need for dorsal and/or caudal septal correction. Endonasal approaches are often adequate and external approaches are utilized for significant L-strut involvement. For severe deformities, extracorporeal septoplasty and anterior septal reconstruction can be utilized. We present an overview of septal deviation repair with technical nuances and advanced reconstruction techniques.

Mandibular Body Fractures.

Fractures of the mandibular body most commonly occur after interpersonal violence or motorized vehicle accident but can occur in athletes. Mandibular body fractures are often associated with additional mandibular fractures. The treatment goal is to achieve preinjury occlusion and facial appearance, and this can be done via a closed reduction and maxillomandibular fixation or open reduction and fixation with or without maxillomandibular fixation. The authors present 3 cases in this article.

Polarization sensitive optical coherence tomography with single input for imaging depth-resolved collagen organizations.

Collagen organization plays an important role in maintaining structural integrity and determining tissue function. Polarization-sensitive optical coherence tomography (PSOCT) is a promising noninvasive three-dimensional imaging tool for mapping collagen organization in vivo. While PSOCT systems with multiple polarization inputs have demonstrated the ability to visualize depth-resolved collagen organization, systems, which use a single input polarization state have not yet demonstrated sufficient reconstruction quality. Herein we describe a PSOCT based polarization state transmission model that reveals the depth-dependent polarization state evolution of light backscattered within a birefringent sample. Based on this model, we propose a polarization state tracing method that relies on a discrete differential geometric analysis of the evolution of the polarization state in depth along the Poincare sphere for depth-resolved birefringent imaging using only one single input polarization state. We demonstrate the ability of this method to visualize depth-resolved myocardial architecture in both healthy and infarcted rodent hearts (ex vivo) and collagen structures responsible for skin tension lines at various anatomical locations on the face of a healthy human volunteer (in vivo).

Management of Traumatic Soft Tissue Injuries of the Face.

Facial soft tissue injuries encompass a broad spectrum of presentations and often present significant challenges to the craniofacial surgeon. A thorough and systematic approach to these patients is critical to ensure that the patient is stabilized, other injuries identified, and the full extent of the injuries are assessed. Initial management focuses on wound cleaning with irrigation, hemostasis, and debridement of nonviable tissue. Definitive management is dependent on the region of the face involved with special considerations for critical structures such as the globe, lacrimal apparatus, facial nerve, and parotid duct. Following sound surgical principles, these injuries can be managed to maximize both functional and aesthetic outcomes while minimizing complications.

Temporalis Tendon Transfer Versus Gracilis Free Muscle Transfer: When and Why?

Temporalis tendon transfer (T3) and gracilis free muscle transfer (GFMT) are popular techniques in lower facial rehabilitation when reinnervation techniques are unavailable. T3 involves a single-stage outpatient procedure resulting in immediate improvement in resting symmetry and a volitional smile. GFMT allows a spontaneous smile, customized vectors, and increased excursion but requires longer surgical time, a delay before movement, and specialized equipment. Ultimately, shared decision making between the clinician and patient should focus on the patient's goals and unique medical condition.

Predicting Resting Oral Commissure Tone Outcomes Following Masseter Nerve Transfer in Facial Reanimation.

Objective: To quantify the degree of oral commissure resting tone improvement in patients undergoing masseter to facial nerve transfer. Methods: A retrospective cohort study was completed in a tertiary academic medical practice. Consecutive cases of masseter nerve transfer patients within a patient database were evaluated from 6/2012 to 9/2017. Inclusion criteria were patients >18 years of age, with complete unilateral paralysis, receiving a masseter to facial nerve transfer, with at least 12 months of recovery, and possessing complete pre- and postoperative data. Patients were excluded if a simultaneous adjunctive procedure was performed so that tone could not be attributed to masseter transfer alone. The main outcome measure was the facial asymmetry index (FAI): the measured difference in distance between the medial canthus and oral commissure of the healthy and paralyzed sides. Results: Twenty-nine patients met inclusion and exclusion criteria and were further analyzed for this study. The oral commissure symmetry improved from 4.7 ± 2.8 mm preoperatively to 2.2 ± 2.3 mm postoperatively. In multivariate analysis, the preoperative FAI was the only significant predictive factor for improvement in commissure symmetry at rest (r = 0.589). This suggests that for each 1.0 mm of worse preoperatively oral commissure asymmetry, the improvement postoperatively was 0.6 mm. Age, gender, body mass index, side of paralysis, duration of paralysis, and recipient branch of facial nerve were not significant predictors in a multivariate analysis. Conclusion: Masseter to facial nerve transfer yields an estimated 60% correction in the oral commissure asymmetry. This estimation may be helpful in determining if adjunctive procedures should be utilized.

Simultaneous Septal Perforation and Deviation Repair with a Chondromucosal Transposition Flap.

Nasal septal perforations can cause issues of epistaxis, whistling, crusting, saddle deformity, and obstruction, which motivate patients to seek surgical repair. Numerous methods of septal perforation repair have been described, with surgical success rates ranging from 52% to 100%, but few studies address situations with concomitant septal deviation. In treating patients with septal perforation and deviation, both issues should be addressed for optimal outcomes. While routine septoplasty involves the removal of septal cartilage, septal perforation repair involves the addition of interposition grafts. The composite chondromucosal septal rotation flap harmoniously combines these seemingly conflicting goals as an effective and efficient technique for septal perforation repair. We present 3 patients successfully treated for their septal perforation and septal deviation concurrently with this technique.

Revision Rhinoplasty: Conservation versus Deconstruction.

Revision rhinoplasty requires the surgeon to strike a careful balance between conservation and deconstruction. Contemporary rhinoplasty has focused on structural cartilage grafts. These grafts resist static and dynamic forces produced by tissue contraction, gravity, and pressure gradients during respiration. However, the simultaneous use of multiple grafts also leads to an increased deconstruction of natural supports. In this article, we discuss some simple yet effective techniques in revision rhinoplasty in a case-based format.
