Background: Nasal septal perforations (NSP) cause a variety of bothersome symptoms for patients, and when medical management fails, surgical repair is indicated. Objective: This study examines the efficacy of a NSP repair method utilizing superficial or deep temporal fascia and a polydiaxonone (PDS) plate scaffold to the prior repair method of a pedicled anterior ethmoid mucosal flap. Methods: A retrospective review of patients who underwent NSP repair at a tertiary academic medical center from 2016-2021. Results: The most common etiologies for NSP were prior nasal surgery, digital trauma, and chronic epistaxis. Compared to the previous repair group with local flaps, the temporalis fascia and PDS plate group had significantly higher rates of complete closure for perforations of all sizes and a lower incidence of revision surgery. Patients also reported improved resolution of symptoms after repair with this new method. Conclusion: The use of temporalis fascia with a PDS plate is a promising surgical method for repair of NSP, regardless of size or etiology. Keywords: septal perforation, polydiaxonone, temporalis

Objective After significant restrictions initially due to the COVID-19 pandemic, otolaryngologists have begun resuming normal clinical practice. However, the risk of SARS-CoV-2 transmission to health care workers through aerosolization and airborne transmission during rhinologic surgery remains incompletely characterized. The objective of this study was to quantify the number concentrations of aerosols generated during rhinologic surgery with and without interventions involving 3 passive suction devices. Study Design Cadaver simulation. Setting Dedicated surgical laboratory. Subjects and Methods In a simulation of rhinologic procedures with and without different passive suction interventions, the concentrations of generated aerosols in the particle size range of 0.30 to 10.0 µm were quantified with an optical particle sizer. Results Functional endoscopic sinus surgery with and without microdebrider, high-speed powered drilling, use of an ultrasonic aspirator, and electrocautery all produced statistically significant increases in concentrations of aerosols of various sizes (P < .05). Powered drilling, ultrasonic aspirator, and electrocautery generated the highest concentration of aerosols, predominantly submicroparticles

The skin is a multilayered organ, equipped with appendages (that is, follicles and glands), that is critical for regulating body temperature and the retention of bodily fluids, guarding against external stresses and mediating the sensation of touch and pain1,2. Reconstructing appendage-bearing skin in cultures and in bioengineered grafts is a biomedical challenge that has yet to be met3–9. Here we report an organoid culture system that generates complex skin from human pluripotent stem cells. We use stepwise modulation of the transforming growth factor β (TGFβ) and fibroblast growth factor (FGF) signalling pathways to co-induce cranial epithelial cells and neural crest cells within a spherical cell aggregate. During an incubation period of 4–5 months, we observe the emergence of a cyst-like skin organoid composed of stratified epidermis, fat-rich dermis and pigmented hair follicles that are equipped with sebaceous glands. A network of sensory neurons and Schwann cells form nerve-like bundles that target Merkel cells in organoid hair follicles, mimicking the neural circuitry associated with human touch. Single-cell RNA sequencing and direct comparison to fetal specimens suggest that the skin organoids are equivalent to the facial skin of human fetuses in the second trimester of development. Moreover, we show that skin organoids form planar hair-bearing skin when grafted onto nude mice. Together, our results demonstrate that nearly complete skin can self-assemble in vitro and be used to reconstitute skin in vivo. We anticipate that our skin organoids will provide a foundation for future studies of human skin development, disease modelling and reconstructive surgery. Skin organoids generated in vitro from human pluripotent stem cells form complex, multilayered skin tissue with hair follicles, sebaceous glands and neural circuitry, and integrate with endogenous skin when grafted onto immunocompromised mice.

Background Patients are increasingly turning to the internet for health education. Due to the complex pathophysiology, clinic-diagnostic profile, and management spectrum of pituitary tumors, an evaluation of the readability of printed online education materials (POEMs) regarding this entity is warranted. Objective (1) To apply established readability assessment tools to internet search results on the topic of pituitary tumors. (2) To identify sources of complexity in order to guide the creation POEMs that are in line with the reading level of the target audience. Methodology: After independent, neutral internet search for the phrase “pituitary tumor,” the first 100 results were subjected to inclusion criteria matching. Analysis was performed using 5 readability assessment tools including Flesch Reading Ease (FRE), Flesch–Kincaid Grade Level (FKGL), Gunning-Fog Score (GFS), Coleman–Liau Index (CLI), and Simple Measure of Gobbledygook (SMOG). Results A total of 82 websites met inclusion criteria. All websites were found to be at a higher reading level ( P Conclusion There is a significant misalignment between the reading level of patients and the readability of pituitary tumor POEMs. This may lead patients to misconceive their diagnoses, management options, and prognosis.

Objective The primary mode of viral transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is thought to occur through the spread of respiratory droplets. The objective of this study was to investigate droplet and splatter patterns resulting from common endoscopic endonasal procedures. Study Design Cadaver simulation series. Setting Dedicated surgical laboratory. Subjects and Methods After instilling cadaver head specimens (n = 2) with fluorescein solution, endoscopic endonasal procedures were systematically performed to evaluate the quantity, size, and distance of droplets and splatter following each experimental condition. Results There were no observable fluorescein droplets or splatter noted in the measured surgical field in any direction after nasal endoscopy, septoplasty with microdebrider-assisted turbinoplasty, cold-steel functional endoscopic sinus surgery (FESS), and all experimental conditions using an ultrasonic aspirator. Limited droplet spread was noted with microdebrider FESS (2 droplets

Purpose There are a variety of implant materials available for orbital floor fracture repair. Implant selection is guided by surgeon experience, availability, and patient specific needs. The purpose of this study is to describe a “wraparound” technique for nylon foil implant placement for large, isolated floor fractures that provides excellent results with low incidence of enophthalmos or other complications. Materials and methods A retrospective chart review from 2012 to 2020 was conducted in patients who underwent isolated orbital floor fracture repair with the use of the “wraparound” nylon foil implant. The surgical technique is described. Preoperative CT scans were assessed, and the patients were divided into groups based on the size of the floor fracture. Postoperative data was collected including Hertel measurements and complications related to the implant. Results There were eighty patients who underwent orbital floor fracture repair with the described technique and had adequate follow-up. There were 18 (22.5%) small-sized fractures, 32 (40%) medium-sized fractures, and 30 (37.5%) large-sized fractures in the study group. One patient (3.33%) in the large fracture group had clinically significant enophthalmos of 2 mm postoperatively. There were no other patients with clinically significant enophthalmos. There were no instances of any complications related to the implant, and no patients required implant removal. Conclusions The “wraparound” technique for a nylon foil implant provides excellent results for isolated orbital floor fractures. It provides more support and stability than traditional nylon implants for larger fractures and has minimal complication rates.

Eyelid coupling using the modified tarsoconjunctival flap is an effective treatment for paralytic ectropion. Eyelid position and quality of life can be improved in patients with flaccid facial paralysis using these eyelid coupling procedures. The modified tarsoconjunctival flap can obscure the lateral visual field by coupling the eyelids, but without distortion of the canthal angle and eyelid margin. The procedure is often coupled with a lateral canthoplasty or canthopexy to address horizontal laxity of the lower eyelid. Collecting standardized outcome measures will help establish the ideal treatment paradigm of paralytic eyelid malposition.

Purpose The COVID-19 pandemic has led to concerns over transmission risk from healthcare procedures, especially when operating in the head and neck such as during surgical repair of facial fractures. This study aims to quantify aerosol and droplet generation from mandibular and midface open fixation and measure mitigation of airborne particles by a smoke evacuating electrocautery hand piece. Materials and methods The soft tissue of the bilateral mandible and midface of two fresh frozen cadaveric specimens was infiltrated using a 0.1% fluorescein solution. Surgical fixation via oral vestibular approach was performed on each of these sites. Droplet splatter on the surgeon's chest, facemask, and up to 198.12 cm (6.5 ft) away from each surgical site was measured against a blue background under ultraviolet-A (UV-A) light. Aerosol generation was measured using an optical particle sizer. Results No visible droplet contamination was observed for any trials of mandible or midface fixation. Total aerosolized particle counts from 0.300–10.000 μm were increased compared to baseline following each use of standard electrocautery (n = 4, p

Purpose Diplopia and ocular motility restriction following orbital fracture repair are common complications. The reported rates in the literature differ greatly, in part due to varying definitions of diplopia and methods of measurement. The purpose of this study is to describe a practical and efficient in-office method for examining ocular motility and diplopia in orbital trauma patients and to report the outcomes in a series of patients who underwent orbital floor fracture repair. Materials and methods A retrospective chart review from 2012 to 2019 was conducted in patients who underwent isolated orbital floor fracture repair within 3 weeks of trauma. All patients had examinations to assess extraocular motility and subjective diplopia using the described techniques. Results Ninety-three patients underwent orbital floor fracture repair and had adequate follow-up. Preoperatively, 71 (76%) patients had some restriction in motility and 59 (63%) patients complained of diplopia. Postoperatively, only 1 patient (1.09%) had clinically significant diplopia. Five (5.4%) additional patients demonstrated mild restriction in supraduction upon detailed ophthalmic examination that was not discovered upon subjective history. No patients had worsening of diplopia or motility after surgery. Conclusions Diplopia and motility restriction following orbital fracture repair can be a persistent problem for some patients. It is important to perform a careful ophthalmic examination to detect motility deficits and diplopia that can be significant to the patient. The true rate of restriction and diplopia may be higher using detailed ophthalmic diagnostic techniques compared to subjective patient history.

As the coronavirus disease 2019 (COVID-19) pandemic continues to evolve through the United States and other countries, differing rates of progression and decline are occurring based on varied population densities. While some health systems are reaching a steady state of new patient cases, others are seeing a leveling off or decline, allowing for restoration of normal practices. This "reverse-surge" planning and implementation process is a colossal undertaking for health systems trying to reacquire patient access and financial stability while preserving necessary resources and maintaining precautions for another potential surge. For the otolaryngologist, reverse-surge planning involves additional workflow adjustments in the outpatient and operating room settings given the abundance of COVID-19 virus in the upper aerodigestive tract. As the reverse-surge best practices are still under development, open communication between otolaryngology colleagues and health system leadership is paramount to optimize efficiency and maintain an adequate measure of safety for patients and our health care teams.

On March 11, 2020, the World Health Organization declared coronavirus disease 2019 a global pandemic. In addition to massive social disruption, this pandemic affected the traditional fellowship interview season for otolaryngology subspecialties, including head and neck surgical oncology, facial plastic and reconstructive surgery, laryngology, rhinology, neurotology, and pediatric otolaryngology. The impact on the fellowship interview process, from the standpoint of the institution and the applicant, necessitated the use of alternative interview processes. This change may alter the future of how interviews and the match proceed for years to come, with nontraditional methods of interviewing becoming a mainstay. While the impact this pandemic has on the fellowship match process is not yet fully realized, this commentary aims to discuss the challenges faced on both sides of the equation and to offer solutions during these unprecedented times.

The anterior lateral thigh osteomyocutaneous free flap (ALTO) offers the advantage of reconstructing large bony and soft tissue defects. We report a novel approach for femur stabilization via retrograde intramedullary nail placement in a patient with a near total tongue and large mandibular defect who underwent ALTO reconstruction that saves operating room time and decreases risk of post-operative fracture.

The utilization of telemedicine has seen a relatively slow progression over the past 50 years in the US health care system. Technological challenges limiting the ease of use of robust video platforms have been a major factor. Additionally, the perception by many health care providers that telehealth is reserved for only the rural population or that it provides limited value due to the inability to perform in-depth physical examinations contributes to the slow adoption. The COVID-19 pandemic, with its massive disruption in social interaction by way of "stay at home" orders, is serving as a catalyst for improving telehealth. Large health systems are investing millions of dollars and increasing telehealth visit numbers 100-fold to access patients. The "telehealth movement" is here to stay and will undoubtedly be incorporated into providers' daily lives years after the COVID-19 pandemic. By embracing virtual access to health care, otolaryngologists will be able to influence improvements to these systems and broaden access options for patient care well into the future.

Importance: In the modern-day health care environment, it is expected that a large proportion of patients will utilize the Internet to gather health care-related information. However, online source...

As otolaryngologists, we identify as subspecialists and fellowship-trained surgeons and may even identify as "super-subspecialists." The likelihood of being redeployed and drawing from knowledge learned during our postgraduate year 1 training seemed exceedingly unlikely until physician resources became scarce in some health care systems during the COVID-19 pandemic. More now than ever, it is evident that our broad training is valuable in helping patients and allowing the otolaryngologist to meaningfully contribute to the larger health care community, especially while the majority (70%-95%) of elective care is delayed. With our skill set, otolaryngologists are poised to support various aspects of hospital wards, intensive care units, emergency departments, and beyond.

Objectives To evaluate research trends, including rates of misrepresentation of scholarly work, in otolaryngology residency applications received by a single institution during the 2018-2019 residency application cycle. Methods After obtaining Institutional Review Board approval, all residency applications to the Department of Otolaryngology-Head and Neck Surgery at Indiana University School of Medicine, Indianapolis, IN for the 2018-2019 cycle were de-identified and analyzed. Demographic and research information including the number of listed peer-reviewed articles/abstracts, types of research projects, and misrepresentations were retrospectively evaluated. Results Our institution received 321 applications, which represented 69.5% of the entire 2018-2019 otolaryngology applicant pool. The average United States Medical Licensing Examination (USMLE) Step 1 score was 246 ±12.4. There were 203 (62.2%) applicants who reported 591 published citations with 20 (6.2%) applicants misrepresenting 26 items (4.4%). Applicants who misrepresented research output had lower average Step 1 scores (237.4 vs 246.4, p

Background Stand-up electric scooters (SES) are a popular public transportation method. Numerous safety concerns have arisen since their recent introduction. Methods A retrospective chart review was performed to identify patients presenting to the emergency departments in Indianapolis, who sustained SES-related injuries. Results A total of 89 patients were included in our study. The average patient age was 29 ± 12.9 years in a predominantly male cohort (65.2%). No patient was documented as wearing a helmet during the event of injury. Alcohol intoxication was noted in 14.6% of accidents. Falling constituted the leading trauma mechanism (46.1%). Injuries were most common on Saturday (24.7%) from 14h00 to 21h59 (55.1%). Injury types included: abrasions/contusions (33.7%), fractures (31.5%), lacerations (27.0%), or joint injuries (18.0%). The head and neck region (H&N) was the most frequently affected site (42.7%). Operative management under general anesthesia was necessary for 13.5% of injuries. Nonoperative management primarily included conservative orthopedic care (34.8%), pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) (34.8%) and/or opioids (4.5%), bedside laceration repairs (27.0%), and wound dressing (10.1%). Individuals sustaining head and neck injuries were more likely to be older (33.8 vs. 25.7 years, p=0.003), intoxicated by alcohol (29.0% vs. 3.9%, p=0.002), and requiring CT imaging (60.5% vs. 9.8%, p

Chondromyxoid fibroma (CMF) is a rare, benign neoplasm of the chondroid, myxoid, and fibrous tissue. It characteristically affects the lower extremity long bones, although it may rarely arise within the craniofacial skeleton. We report the diagnosis and management of a 31-year-old male with a large, incidentally discovered CMF originating from the sphenoid sinus. A subsequent review of the literature reveals the need to differentiate from more aggressive neoplasms, such as chondrosarcoma and chondroma, which share radiographic features. A histopathologic examination is crucial for proper diagnosis and treatment. We discuss clinical sequelae, highlight the importance of a thorough pre-operative evaluation, and summarize previously suggested treatment paradigms.

Objective To determine radiologic preferences of practicing otolaryngologists regarding isolated nasal bone fractures. Study design An 8-question survey on isolated nasal bone fractures was designed. Setting Surveys were sent to all otolaryngology residency program directors for distribution among residents and faculty. Additional surveys were distributed to private practice otolaryngology groups. Results 140 physicians responded to the survey. 57% of the respondents were practicing otolaryngologists (75% with 10+ years of experience), while 43% of respondents were residents-in-training. 56% of respondents treated 1–5 nasal bone fractures per month. 80% of all respondents reported imaging being performed prior to consultation. If imaging was obtained before consultation, plain films and computed tomography (CT) maxillofacial/sinus scans were the most frequent modalities. 33% of residents and 70% of practicing otolaryngologists report imaging as ‘rarely’ or ‘never’ helpful in guiding management. 42% of residents and 20% of practicing otolaryngologists report asking for imaging when it wasn't already obtained. Decreased use of radiography was associated with greater years in practice and higher frequency of fractures treated. Conclusions and relevance Otolaryngologists seldom request imaging to evaluate and treat isolated nasal bone fractures. When ordered, imaging is utilized more often among residents-in-training and non-otolaryngology consulting physicians. This study highlights an opportunity to educate primary care and emergency room providers as well as otolaryngology residents on the value of comprehensive physical exam over radiographic imaging in the work-up of isolated nasal fractures. In addition, widespread adoption of a “no x-ray policy” in this setting may result in better resource utilization.

Background The taboo of avoiding nonsteroidal anti-inflammatory drugs (NSAIDs) after functional endoscopic sinus surgery (FESS) has been waning. The impetus to reduce opioid prescriptions in view of the opioid epidemic led the authors to change their practices to include NSAIDs after sinus surgery. This study's aim was to analyze the differences between patients before and after we began recommending NSAIDs after FESS. Methods A prospective cohort study was performed on patients undergoing FESS or other endoscopic nasal surgeries at 3 institutions, by 5 rhinologists and 1 facial plastic surgeon. Before introducing NSAIDs, all patients were given a prescription for hydrocodone-acetaminophen 5/325 mg and also recommended preferentially to use acetaminophen 325 mg. After the addition of NSAIDs, ibuprofen 200 mg and acetaminophen 325 mg were recommended preferentially, using the narcotic as a rescue medication. Patients kept a pain diary and medication log, and gave a visual analog scale (VAS) score for overall pain. Demographics, surgical variables, and comorbidities were also analyzed. Results One hundred sixty-six total patients were recruited and had data that could be analyzed (65 without NSAIDs, 101 with NSAIDs). Overall, mean pain VAS score was 3.12 ± 1.95 for the non-NSAID group and 2.33 ± 2.30 for the NSAID group (p value = 0.006). The day with the highest mean pain was the first postoperative day. The mean number of total opioid pills taken was 6.94 ± 6.85 without NSAIDs vs 3.77 ± 4.56 with NSAIDs (p = 0.018). Age and gender were found to be the only consistently significant patient variables to affect pain. There were no bleeding complications. Conclusion NSAID use was introduced into the practices of 5 practicing rhinologists and 1 facial plastic surgeon. No bleeding complications were seen. Both pain and overall opioid usage were reduced significantly.

Objectives/hypothesis To assess the face, content, construct, and concurrent validity of the PHACON Sinonasal Surgery Simulator (SNSS). Study design Prospective cohort study. Methods A total of 12 otolaryngology residents were recruited to perform sinonasal surgery on the simulator followed by cadaveric heads. Resident performances were recorded and de-identified. Face and content validities were evaluated based on 5-point Likert scale questionnaires. The recordings were evaluated by extramural expert rhinologists based on a validated Global Rating Scale (GRS). These results were analyzed and compared to assess construct and concurrent validity. Results The appearance of anatomic structures was rated as realistic by 75% of all participants, while only 30% and 41.7% rated the mucosal and bony tissues as realistic, respectively. A total of 91.7% of participants found the model useful for teaching anatomy, while 66.7% said it was useful for teaching operative technique. Construct validity was confirmed by showing significant differences in performance between the novice and experienced groups. Concurrent validity was confirmed by showing significant correlation between performance on the model and gold standard (i.e. cadaver head). Conclusions This study demonstrates the face, content, concurrent, and construct validity of a 3D-printed SNSS. Although this model has the potential to be a valuable tool in endoscopic sinus surgery training for otolaryngology residents, improvements are required with respect to the quality of simulated mucosal tissue as well as the simulated anatomy of the fronto-ethmoid compartment Level of Evidence: NA Laryngoscope, 2019.

Purpose The safety profile of the transcutaneous medial canthal incision for access to the medial orbit is assessed with a focus on the risk of post-operative iatrogenic epiphora. Methods A retrospective chart review of patients undergoing medial orbitotomy via the transcutaneous medial canthal incision was performed. Patients with a minimum of 3 months of follow-up were included and post-operative complications were assessed and characterized. Results One-hundred-fifty patients were included in the study. A total of 4 complications were identified, including one each of the following: nasolacrimal duct obstruction, hypertrophic scar, suture granuloma and soft tissue infection. Only the nasolacrimal duct obstruction required surgical intervention. Discussion Access to the medial orbit has been achieved through a variety of approaches, each with their own benefits and risk profile. The transcaruncular approach has increased in usage as a means to avoid a visible cutaneous scar and decrease the risk of iatrogenic epiphora, however, there are specific patients who may have relative contraindications to this approach. The current study demonstrates the low risk profile of the transcutaneous medial canthal incision, specifically the minimal risk of iatrogenic damage to the nasolacrimal outflow system. This approach is another useful tool which orbit surgeons should be familiar with to offer as an option to patients requiring medial orbitotomy.

Nasal airway obstruction is a common complaint encountered by the otolaryngologist. In-office nasal procedures are becoming increasingly popular and should be considered for patients desiring immediate treatment without the adverse effects of general anesthesia, operating room costs, or scheduling delays. This article discusses the factors in patient selection, room setup, and other considerations. The options available for in-office treatment of nasal valve repair are discussed, including turbinoplasty, septoplasty, and nasal valve repair/functional rhinoplasty-type techniques described in the literature.

Purpose To examine the incidence of intracapsular hemorrhage in orbital fracture repair with non-fixated nylon sheet implants. Methods A retrospective chart review of 227 patients presenting from January 2013 to December 2016 for orbital fracture repair with nylon sheet implants. Results Of the 331 orbital fractures repaired over 4 years, a total of 227 met inclusion criteria. The average implant thickness was 0.38 mm and no implants were fixated. Four total implants (1.8%) were removed due to complications; one each secondary to exploration for ongoing postoperative diplopia, immediate post-operative orbital hemorrhage, a cystic mass anterior to the implant, and pain. There were no cases of intracapsular hemorrhage nor infection for any of the 227 patients over 4 years. Conclusions To the authors knowledge, this represents the largest case series to date to assess the rate of intracapsular hemorrhage in non-fixated nylon sheet orbital implants. In the 227 cases reviewed over a 4-year period, there were no cases of intracapsular hemorrhage. This suggests a much lower complication rate than previously reported. Precis A case series of 227 patients who underwent orbital fracture repair with non-fixated nylon sheet implants.

Objectives/Hypothesis Assess long-term patient satisfaction with conventional thyroidectomy scars and the impact of thyroidectomy scars on patient quality of life. Study Design Validated survey administration and retrospective review of clinical and demographic data. Methods Patients who underwent conventional thyroidectomy through years 2000 to 2010 were identified and administered the validated Patient Scar Assessment Questionnaire. Mean satisfaction, appearance and scar-consciousness scores were determined. Thirty-seven patients also measured the length of their current scar. Patient demographic and operative data were collected retrospectively from the medical record. Data were analyzed with one-way analysis of variance and independent samples t testing. Results Sixty of 69 patients perceived the appearance of their scar to be “good” or “excellent.” Sixty-three patients (91.3%) were satisfied with all scar outcomes; 67 (97.1%) were satisfied with the overall appearance of their scar. Mean total satisfaction score was 17.3 (

Purpose To describe the eyelid condition known as “floppy eyelid syndrome” and to present the results of our experience treating patients with floppy eyelid syndrome. Methods A retrospective analysis of 16 patients from 2009 to 2013 who underwent combined medial canthopexy and lateral tarsal strip by two surgeons (HBL and WRN) for the treatment of floppy eyelid syndrome (FES). Age, gender, presence of obstructive sleep apnea (OSA), papillary conjunctivitis, punctate keratopathy and lash ptosis were recorded pre-operatively. Outcomes assessed included improvement in upper eyelid laxity, operative complications, post-operative symptomatic relief and delayed recurrence of FES. Results A total of 18 procedures (on 36 eyelids) were performed on 16 patients over the 4-year period. All patients (18/18) had relief of symptoms and good functional results, defined as improvement in lid laxity and resolution of symptoms. Average follow up was 124 days. 8 of 16 patients (50%) had a pre-existing diagnosis of OSA. The remaining 8 patients were referred for sleep study and 2 were subsequently diagnosed with OSA. Two patients experienced some degree of FES recurrence without return of symptoms. There was one complication reported in which a partial dehiscence of the lateral canthal tendon occurred which did not require operative revision. Conclusions Combined medial canthopexy and lateral tarsal strip are a safe and effective technique for the treatment of floppy eyelid syndrome. There is a strong association of FES and OSA and it is important to have any patient diagnosed with FES evaluated for OSA.

Purpose To report a series of patients with extra-ocular movement restriction and diplopia after orbital fracture repair, and determine the effect of timing of repair and the type of implant used. Methods A chart review was conducted identifying all patients > 18 years of age at our institution between June 2005 and June 2008 who underwent orbital fracture repair, and presented with clinically significant diplopia and extra-ocular movement restriction persisting longer than one month after repair. Data collected included timing of repair, implant used within the orbit, and need for revision. Results Ten patients were identified with a mean time to primary orbital fracture repair at 9 days (range 1–48). Seven patients underwent revision of their orbital fracture repair with removal of the previously placed implant and replacement with non-porous 0.4 mm Supramid Foil, whereas one patient underwent lateral and inferior rectus recessions without revision of primary fracture repair. Titanium mesh was the intra-orbital implant found in all patients requiring revision of orbital fracture repair. All revisions resulted in resolution of clinically significant diplopia. Conclusions Clinically significant diplopia and extra-ocular movement restriction is not an uncommon complication after orbital fracture repair. In our series, there was a strong association between these complications and the use of porous titanium mesh implants. Revision of fractures significantly improved diplopia in all but one patient. This suggests that meticulous fracture repair and the use of non-porous implants primarily or secondarily may preclude the need for strabismus surgery after orbital trauma.

Introduction The highly contagious COVID-19 has resulted in millions of deaths worldwide. Physicians performing orbital procedures may be at increased risk of occupational exposure to the virus due to exposure to secretions. The goal of this study is to measure the droplet and aerosol production during repair of the inferior orbital rim and trial a smoke-evacuating electrocautery handpiece as a mitigation device. Material and methods The inferior rim of 6 cadaveric orbits was approached transconjunctivally using either standard or smoke-evacuator electrocautery and plated using a high-speed drill. Following fluorescein inoculation, droplet generation was measured by counting under ultraviolet-A (UV-A) light against a blue background. Aerosol generation from 0.300–10.000 μm was measured using an optical particle sizer. Droplet and aerosol generation was compared against retraction of the orbital soft tissue as a negative control. Results No droplets were observed following the orbital approach using electrocautery. Visible droplets were observed after plating with a high-speed drill for 3 of 6 orbits. Total aerosol generation was significantly higher than negative control following the use of standard electrocautery. Use of smoke-evacuator electrocautery was associated with significantly lower aerosol generation in 2 of 3 size groups and in total. There was no significant increase in total aerosols associated with high-speed drilling. Discussion and conclusions Droplet generation for orbital repair was present only following plating with high-speed drill. Aerosol generation during standard electrocautery was significantly reduced using a smoke-evacuating electrocautery handpiece. Aerosols were not significantly increased by high-speed drilling.

The review article presents an expansive list of otolaryngology-specific surgical simulation training models as described in Otolaryngology literature as well as evaluates recent advances in simulation training in Otolaryngology.

Functional and anatomical outcomes after surgical repair of facial nerve injury may be improved with the addition of polyethylene glycol (PEG) to direct suture neurorrhaphy. The application of PEG has shown promise in treating spinal nerve injuries, but its efficacy has not been evaluated in treatment of cranial nerve injuries.To determine whether PEG in addition to neurorrhaphy can improve functional outcomes and synkinesis after facial nerve injury.In this animal experiment, 36 rats underwent right facial nerve transection and neurorrhaphy with addition of PEG. Weekly behavioral scoring was done for 10 rats for 6 weeks and 14 rats for 16 weeks after the operations. In the 16-week study, the buccal branches were labeled and tissue analysis was performed. In the 6-week study, the mandibular and buccal branches were labeled and tissue analysis was performed. Histologic analysis was performed for 10 rats in a 1-week study to assess the association of PEG with axonal continuity and Wallerian degeneration. Six rats served as the uninjured control group. Data were collected from February 8, 2016, through July 10, 2017.Polyethylene glycol applied to the facial nerve after neurorrhaphy.Functional recovery was assessed weekly for the 16- and 6-week studies, as well as motoneuron survival, amount of regrowth, specificity of regrowth, and aberrant branching. Short-term effects of PEG were assessed in the 1-week study.Among the 40 male rats included in the study, PEG addition to neurorrhaphy showed no functional benefit in eye blink reflex (mean [SEM], 3.57 [0.88] weeks; 95% CI, -2.8 to 1.9 weeks; P = .70) or whisking function (mean [SEM], 4.00 [0.72] weeks; 95% CI, -3.6 to 2.4 weeks; P = .69) compared with suturing alone at 16 weeks. Motoneuron survival was not changed by PEG in the 16-week (mean, 132.1 motoneurons per tissue section; 95% CI, -21.0 to 8.4; P = .13) or 6-week (mean, 131.1 motoneurons per tissue section; 95% CI, -11.0 to 10.0; P = .06) studies. Compared with controls, neither surgical group showed differences in buccal branch regrowth at 16 (36.9 motoneurons per tissue section; 95% CI, -14.5 to 22.0; P = .28) or 6 (36.7 motoneurons per tissue section; 95% CI, -7.8 to 18.5; P = .48) weeks or in the mandibular branch at 6 weeks (25.2 motoneurons per tissue section; 95% CI, -14.5 to 15.5; P = .99). Addition of PEG had no advantage in regrowth specificity compared with suturing alone at 16 weeks (15.3% buccal branch motoneurons with misguided projections; 95% CI, -7.2% to 11.0%; P = .84). After 6 weeks, the number of motoneurons with misguided projections to the mandibular branch showed no advantage of PEG treatment compared with suturing alone (12.1% buccal branch motoneurons with misguided projections; 95% CI, -8.2% to 9.2%; P = .98). In the 1-week study, improved axonal continuity and muscular innervation were not observed in PEG-treated rats.Although PEG has shown efficacy in treating other nervous system injuries, PEG in addition to neurorraphy was not beneficial in a rat model of facial nerve injury. The addition of PEG to suturing may not be warranted in the surgical repair of facial nerve injury.NA.

IMPORTANCE: In the setting of facial paralysis, inadequate eyelid closure and lower eyelid ectropion can lead to corneal exposure and impaired quality of life. Repair of paralytic ectropion is challenging, and an ideal surgical approach for all cases has not been identified. OBJECTIVE: To assess the patient-reported outcomes and eyelid position improvement in patients with flaccid facial paralysis undergoing lateral eyelid coupling with a tarsal strip canthoplasty and modified tarsoconjunctival flap to correct eyelid malposition. DESIGN, SETTING, AND PARTICIPANTS: Review of medical records of adults with flaccid facial paralysis who underwent a single-stage tarsal strip canthoplasty and modified tarsoconjunctival flap at a tertiary academic center. Inclusion criteria included a minimum of 3 months of follow-up. INTERVENTION: The lateral upper and lower eyelid are coupled with the hybrid tarsoconjunctival flap. MAIN OUTCOMES AND MEASURES: Patient-reported outcome measures and objective photograph analysis. Preoperative and postoperative Facial Clinimetric Evaluation (FaCE) scores and Moe Ectropion Grading Scale scores were compared. The relationship between radiation therapy (RT) and outcomes was analyzed. RESULTS: Sixteen patients (8 [50%] female; mean [SD] age at surgery, 71.5 [9.6] years) were identified between January 2014 and August 2017. Twelve (75%) had paralysis from facial nerve sacrifice during cancer ablation. The mean time between paralysis and referral for surgical repair of ectropion was 23 months (range, 0-151 months) and mean follow-up after surgery was 9.8 months (range, 3-39 months). The most common symptom was epiphora, which was significantly reduced after surgery (75% vs 25%; P = .01). Median Moe Ectropion Grading Scale score improved from 3 (interquartile range, 2-3) to 0 (interquartile range, 0-1; P

Objective Three-dimensional (3D)-printing technology is being employed in a variety of medical and surgical specialties to improve patient care and advance resident physician training. As the costs of implementing 3D printing have declined, the use of this technology has expanded, especially within surgical specialties. This article explores the types of 3D printing available, highlights the benefits and drawbacks of each methodology, provides examples of how 3D printing has been applied within the field of otolaryngology-head and neck surgery, discusses future innovations, and explores the financial impact of these advances. Data Sources Articles were identified from PubMed and Ovid MEDLINE. Review Methods PubMed and Ovid Medline were queried for English articles published between 2011 and 2016, including a few articles prior to this time as relevant examples. Search terms included 3-dimensional printing, 3 D printing, otolaryngology, additive manufacturing, craniofacial, reconstruction, temporal bone, airway, sinus, cost, and anatomic models. Conclusions Three-dimensional printing has been used in recent years in otolaryngology for preoperative planning, education, prostheses, grafting, and reconstruction. Emerging technologies include the printing of tissue scaffolds for the auricle and nose, more realistic training models, and personalized implantable medical devices. Implications for Practice After the up-front costs of 3D printing are accounted for, its utilization in surgical models, patient-specific implants, and custom instruments can reduce operating room time and thus decrease costs. Educational and training models provide an opportunity to better visualize anomalies, practice surgical technique, predict problems that might arise, and improve quality by reducing mistakes.

Objective To determine how patients seeking cosmetic rhinoplasty analyze themselves compared to their surgeon's analysis. Simply stated, “Does your surgeon view your nose the same as you?” Study design Prospective, blinded study. Methods All primary rhinoplasty consultations completed a nasal analysis questionnaire. The patients’ facial plastic surgeons completed an identical questionnaire. The results were compared and analyzed. Results Data underwent statistical analysis and subsequent factor analysis was performed. 132 patients participated in the study. Questions were grouped together based on factors: overall appearance, skin quality, tip dimensions, straightness, nostril show, and width. The only factor with reasonable surgeon/patient correlation was factor 1, overall appearance, with correlation 0.6473, p Conclusions Surgeons and patients are in agreement with the overall appearance of the nose, but differ in their analysis regarding the details. This information can be used to guide future discussions during consultations and most importantly help to better gauge and manage patient expectations.

Importance Reconstruction of the midface remains a challenging task for even the most experienced surgeon, with a host of reconstructive options including free tissue transfer, allografts, or prosthetic implants. Presented here is a case of idiopathic bony destruction of the right midface in a 19 year old female, creating a unique defect requiring repair. Objective Demonstrate a unique case of severe maxillary degeneration and discuss the associated reconstructive challenges and final repair with a prosthetic implant. Design Case report. Results The patient presented with a 7 month history of an idiopathic progressive deformity of the right cheek. Computed tomography of the paranasal sinuses revealed extensive bone loss of the right midface and orbit. The patient underwent facial reconstruction using a customized Medpor (Stryker Corp, Kalamazoo, MI) implant. At 6 month follow-up the patient and physician were both pleased with the patient's overall appearance. The patient did have some residual lower lid retraction present as well as some lateral pull at the lateral canthus outward from the orbit itself. Conclusions Preoperative planning for midface reconstruction requires a deep understanding of the aesthetic, functional, and supportive roles this structure holds. Computer assistance allows the creation of custom made implants, providing the reconstructive surgeon with innovative options for reconstruction with minimal morbidity to the patient. As the technology around the design and creation of the custom implants continues to improve, the role of computer assistance in reconstruction will become more prominent.

Straightening a crooked nose is a challenge. Several techniques exist ranging from simple to technically complex. It is important to approach the nose systematically and to remember that perfection may be impossible to achieve. If straightening is not attainable, softening grafts or onlay grafts should be used to camouflage subtle irregularities.

IMPORTANCE: The introduction and evaluation of a novel technique to create nasal prostheses with 3-dimensional (3-D) imaging software may circumvent the need for an anaplastologist. OBJECTIVES: To describe a novel computer algorithm for the creation of a 3-D model of a nose and to evaluate the similarity of appearance of the nasal prosthesis with that of the individual’s nose. DESIGN, SETTING, AND PARTICIPANTS: A prospective pilot study with a cross-sectional survey was conducted from August 1 to October 31, 2016, at a tertiary care academic center. Five volunteers were used for creation of the nasal prostheses, and 36 survey respondents with a medical background were involved in evaluating the nasal prostheses. EXPOSURES: A computer algorithm using a 3-D animation software (Blender; Blender Foundation) and Adobe Photoshop CS6 (Adobe Systems) were used to create a 3-D model of a nose. Photographs of 5 volunteers were processed with the computer algorithm. The model was then printed using a desktop 3-D printer. Attending physicians, residents, and medical students completed a survey and were asked to rate the similarity between the individuals’ photographs and their 3-D printed nose on a Likert-type scale. MAIN OUTCOMES AND MEASURES: The similarity between 3-D printed nasal models and photographs of the volunteers’ noses based on survey data. RESULTS: Thirty-six survey respondents evaluated 4 views for each of the 5 modeled noses (from 4 women and 1 man; mean [SD] age, 26.6 [5.7] years). The mean (SD) score for the overall similarity between the photographs and the 3-D models was 8.42 (1.34). The mean scores for each nasal comparison ranged from 7.97 to 8.62. According to the survey, respondents were able to match the correct 3-D nose to the corresponding volunteers’ photographs in 171 of 175 photographs (97.7%). All surveyed clinicians indicated that they would consider using this tool to create a temporary prosthesis instead of referring to a prosthodontist. CONCLUSIONS AND RELEVANCE: This algorithm can be used to model and print a 3-D prosthesis of a human nose. The printed models closely depicted the photographs of each volunteer’s nose and can potentially be used to create a temporary prosthesis to fill external nasal defects. The appropriate clinical application of this technique is yet to be determined.

Objectives Laryngeal transplantation research has been studied in various animal models. For in-depth, immunology-based transplantation research, however, a thoroughly studied animal model must exist. The purpose of this study was to develop a reliable surgical technique in mice to serve as a model for further study of laryngeal transplantation. Methods Heterotopic laryngeal transplantation was attempted in 15 immunocompetent mice by use of modifications of previously described techniques established in rats. Results Various microvascular techniques were used that led to 8 successful transplants (of 15) with patent vascularity at the time of sacrifice. The first 7 attempts at transplantation were unsuccessful because of technical difficulties related to vessel size, soft tissue traumatic injury, and venous congestion. Subsequently, 8 transplantation procedures were successfully performed after modifications of the surgical technique. Conclusions This pilot study describes the reproducible surgical techniques performed in using mice for studying laryngeal transplantation. Mice are cost-effective and immunologically well studied, and are thus ideal for further laryngeal transplantation research.

Objective: Traditional immunosuppressive regimens make laryngeal transplantation in cancer patients prohibitive because of the increased risk of recurrence. Everolimus, a recently developed immunosuppressant, has demonstrated significant antitumor properties. The purpose of this study was to examine the effects of everolimus alone and in combination with other immunosuppressants on tumor growth in a combined laryngeal transplantation and tumor model. Study Design: Animal, prospective, randomized, controlled, and blinded. Methods: One million squamous cell carcinoma cells (SCC-158) were injected intravenously into a total of 40 rats 1 day before laryngeal transplantation. Rats were divided into four groups differing by immunosuppressive regimens. Lung surface metastases were counted 21 days after inoculation, and numerical transplantation rejection scores were recorded. A separate experiment for comparison was performed with no transplant on 24 rats, but with the same immunosuppressive treatment groups. Results: The median number of lung surface metastases were: a) control (i.e., no immunosuppression): 85; b) everolimus 1.0 mg/kg: 25; c) tacrolimus 1.2 mg/kg: 1650; d) everolimus 1.0 mg/kg + tacrolimus 0.05 mg/kg: 1300. Rats receiving everolimus alone showed a statistically significant decrease in pulmonary surface metastases compared with the other groups. Transplanted rats had no difference in their outcomes when compared with nontransplanted rats. Conclusion: Everolimus significantly decreases SCC-158 growth in our combined transplantation and tumor model compared with controls and other immunosuppressants.

Functional rhinoplasty is a term that is commonly used to describe any technique used to address nasal obstruction in the nasal valve region. The cause of nasal valve collapse differs based on the site. Internal valve collapse may be idiopathic or associated with previous rhinoplasty, trauma, or weakened cartilage in older patients. External valve collapse is usually idiopathic and less likely to be associated with previous surgery. Various techniques have been developed over time, and the data in support of functional rhinoplasty continue to increase.This article discusses popular techniques currently in use, as well as newer techniques that have been described over the past several years. In addition, there is a trend toward utilizing objective testing and validated assessment scales to assess postoperative changes.Functional rhinoplasty utilizes a multitude of techniques to address nasal valve collapse. Although high-level data are lacking, the current literature is in support of nasal valve correction to improve nasal breathing. Most importantly, the technique employed is unique for each patient.
