Reducing Risks for Poor Surgical Wound Healing.

This review summarizes common risk factors for poor surgical healing on the face and neck and a generalized approach to treating a delayed healing wound. During the preoperative evaluation patients should be screened for prior irradiation, cigarette or e-cigarette use, chronic steroid use, alcoholism, diabetes, malnutrition, and other chronic medical conditions and medications. Despite the surgeon's best efforts to prevent poor surgical healing, some wounds may display signs of persistent inflammation. The facial plastic surgeon should be astute in recognizing delayed healing and identifying intrinsic and extrinsic risk factors so that timely intervention can be performed.

Role of sentinel lymph node biopsy for oral squamous cell carcinoma: Current evidence and future challenges.

Sentinel lymph node biopsy (SLNB) has been used across oncological specialties for prognostication, staging, and identification of occult nodal metastasis. Recent studies demonstrated the potential clinical utility of SLNB in oral cavity squamous cell carcinoma (OCSCC). Elective neck dissection is the current standard of care in early management of OCSCC with depth of invasion greater than 2-4 mm; however, majority of patients ultimately do not have nodal disease on final pathology. SLNB is an alternative procedure widely adopted in early cancer management in many oncological subspecialities. Several considerations such as depth of invasion, nodal mapping, histopathology methods, operator variability, postoperative complications, and advancement in preoperative and intraoperative imaging technology can guide the appropriate application to SLNB in OCSCC. The aim of this review is to discuss the current evidence for SLNB in the treatment of early stage OCSCC, imaging technologies that support SLNB procedures, and studies that are currently underway.

Commentary on: "Tri-Vector Gracilis Microneurovascular Free Tissue Transfer with Periocular Component to Achieve a Duchenne Smile in Patients with Facial Paralysis" by Byrne et al.

In this commentary, we review Dr. Byrne and colleagues' article "Tri-vector Gracilis Microneurovascular Free Tissue Transfer with Periocular Component to Achieve a Duchenne Smile in Patients with Facial Paralysis." The authors successfully demonstrate the feasibility of separating the gracilis muscle into three bellies while maintaining neuromuscular input to achieve restoration of lower lid movement during smile, resulting in a more natural appearing or "Duchenne smile." Although the concept of spontaneity remains controversial, beautiful smile outcomes are illustrated in the featured photograph and videos.

Clinical factors associated with lower health scores in COVID-19-related persistent olfactory dysfunction.

BACKGROUND: Patients with persistent COVID-19 olfactory dysfunction (OD) commonly report parosmia. Understanding the impact of COVID-19 OD and parosmia is critical to prioritizing research and interventions. In this study we investigate the impact of parosmia and other clinical and disease characteristics on health state utility values (HUVs) for those with persistent COVID-19 OD. METHODS: Patients with a history of COVID-19 diagnosis and persistent OD were recruited from a tertiary medical center and a social media support forum for chemosensory dysfunction. Clinical characteristics and disease-specific symptoms were obtained along with self-reported history of smell function and presence of parosmia. HUVs were calculated using indirect (EuroQol 5-Dimension [EQ-5D]) and direct (VAS) measures. RESULTS: Our study included 286 subjects (75.52% women) with persistent COVID-19-related OD. Results (mean ± standard deviation) of HUVs based on EQ-5D and VAS were 0.81 ± 0.14 and 0.73 ± 0.21, respectively. Mean self-reported smell function (on a 0-10 scale) was 9.67 ± 1.25 pre-COVID-19, 0.93 ± 2.34 at diagnosis, and 3.39 ± 2.32 at most current assessment. A total of 89.16% of the subjects reported parosmia and 24.13% sought medical care for anosmia. Seeing an MD for OD (p < 0.001), female gender (EQ-5D only, p = 0.002), a history of chronic pain (p < 0.05) and depression/anxiety (EQ-5D only, p < 0.001) predicted worse health. Parosmia and persistent symptoms, such as shortness of breath, were associated with lower EQ-5D and VAS scores, but did not independently predict poorer health scores on multivariable analysis. CONCLUSION: Persistent COVID-19 OD results in health states comparable to other chronic diseases.

Novel Implementation of Virtual Interviews for Otolaryngology Resident Selection: Reflections Relevant to the COVID-19 Era.

To address financial and scheduling conflicts associated with residency interviews for otolaryngology candidates, our residency program implemented virtual interviews as an alternative to the traditional in-person format for our visiting subinterns during the 2018-2019 and 2019-2020 interview cycles. Applicants then completed an anonymous survey about their interview experience. We found that, overall, positive attitudes toward virtual interviews increased among 2019-2020 candidates as compared with the year prior. Our results demonstrated an average cost savings per interview of $500 to $1000 when virtual technology was utilized. Based on feedback, improvements may be considered regarding eye contact, minimizing distractions, and providing the option to extend the interview length. Our experience provides a preliminary framework for transitioning to virtual interviews in the upcoming 2020-2021 otolaryngology residency selection process during the COVID-19 era, as well as for future studies assessing the utility of this method and its impact on overall match statistics.

Coronavirus Disease-19 and Rhinology/Facial Plastics.

This review summarizes the challenges and adaptations that have taken place in rhinology and facial plastics in response to the ongoing coronavirus disease-19 pandemic. In particular, the prolonged exposure and manipulation of the nasal and oral cavities portend a high risk of viral transmission. We discuss evidence-based recommendations to mitigate the risk of viral transmission through novel techniques and device implementation as well as increasing conservative management of certain pathologies.

Clinically relevant behavioral endpoints in a recurrent nitroglycerin migraine model in rats.

BACKGROUND: This research sought to further validate the rat nitroglycerin (NTG) migraine model by comparing the effects of single versus recurrent NTG episodes on behavioral endpoints that mirror ICHD-3 diagnostic criteria for migraine, and to determine if the altered behavioral endpoints are reduced after administration of sumatriptan. METHODS: Separate cohorts of rats were administered NTG (10 mg/kg/2 ml) or saline (Experiment 1: single injection; Experiment 2: repeated injections; Experiment 3: repeated injections with sumatriptan [0.0, 0.3 and 1.0 mg/kg/ml] rescue. Behavioral endpoints were assessed 2 h after final NTG administration and included time in light/dark chambers for photophobia and activity, pain facial ratings, and cool (5 °C) and warm (46 °C) tail dip. RESULTS: The first two experiments demonstrated that repeated (n = 5) but not single NTG injections produced photophobia, decreased activity, and yielded less weight gain than saline injections. Experiment 3 showed that sumatriptan attenuated hypoactivity, reduced facial expressions of pain, and reversed weight alterations in a dose-dependent manner. CONCLUSIONS: These findings identify numerous clinical homologies of a recurrent NTG rat migraine model that may be useful for screening novel pharmacotherapies.
