Normative Values of the Nasal Obstruction Symptom Evaluation Scale.

Background: The Nasal Obstruction Symptom Evaluation (NOSE) scale is widely used by clinicians in evaluation of nasal airway obstruction (NAO). Objective: To determine normative values for the NOSE scale among both symptomatic and asymptomatic members of the general U.S. population. Methods: A survey of NAO symptoms in adults of age 18 years and older was performed. The distribution of NOSE scores among the general population was estimated. Influence of features including age, gender, race, location, and symptomatology on NOSE scores was evaluated. Results: Surveys were completed by 2333 participants. Mean NOSE score was 11 (standard deviation [SD] 11) in the asymptomatic, and 28 (SD 22) in the symptomatic population (p < 0.0001). Increasing age was associated with an increase in scores until 45 years, after which it was associated with decreasing scores. No significant differences were found related to other investigated demographics. Conclusions: Normative ranges for the NOSE scale are established, and are largely consistent with values in the existing literature. NOSE scores do not appear to be influenced by gender, race, or geography, although age should be considered in their interpretation.

Professional Social Media in Facial Plastic and Reconstructive Surgery: Usage, Resources, and Barriers.

BACKGROUND: Social media is an important tool for networking, recruitment, and promoting clinical practice. No study has specifically assessed which FPRS practitioners have professional social media accounts, how they utilize them, and what barriers or resources exist to their use. OBJECTIVES: This study aims to examine differences in social media use based on provider demographics and practice setting, and identify resources and barriers to professional social media use. METHODS: This cross-sectional analysis was an anonymous survey sent to AAFPRS members. Data collected included demographics, practice setting, resources, and barriers encountered to use of professional social media. RESULTS: Most facial plastic surgeons (80%) use professional social media, notably Instagram and Facebook, and mostly post patient photos and stories (67.9%). Social media is more commonly utilized in private practice (56% vs 23%, P = .0016), where there are less institutional barriers (10% vs 40%, P = .02) and more resources available (82.5% vs 12.5%, P = .01). CONCLUSIONS: Social media is widely used in FPRS. Working in private practice is associated with increased availability of resources for support, and a reduction in institutional barriers to maintaining a social media presence. With this understanding, facial plastic surgeons can be better equipped for networking, marketing, and promoting the field of FPRS.

Complications Associated with Use of Porous High-Density Polyethylene in Rhinoplasty.

Background: Porous high-density polyethylene (pHDPE) has successfully been used as an alternative to cartilage for grafting in rhinoplasty; however, concerns exist surrounding its potential for infection and/or extrusion. Objectives: To analyze the relationship between complication rates associated with pHDPE in rhinoplasty and graft location relative to shear force applied by external manipulation. Methods: Retrospective review of 116 patients undergoing pHDPE rhinoplasty for 10 years. Results: Minor postoperative complications occurred in 3.4% of patients, each resolving with conservative management. Major complications including infection or extrusion occurred in 5.2% of all patients, at an average of 36.9 months postoperatively. All major complications occurred in patients with grafts extending into the caudal nose, and two-thirds ultimately necessitated surgical intervention. Conclusions: Cephalically contained pHDPE grafts are less prone to failure than those extending into the caudal nose. Long-term follow-up is recommended for all patients based on the risk for delayed complications.

Augmented Skin Grafting: A New Rung in the Reconstructive Ladder.

Importance: A gap in the reconstructive ladder exists in which complex defects may benefit from skin grafting but are not amenable due to their anatomic limitations. Similarly, some patients are intolerant of more invasive techniques in cosmetically sensitive areas. In these scenarios, augmented skin grafts may represent a unique alternative to traditional reconstructive options. Observations: This report is a clinical overview of skin grafting in complex nasal defects. We describe three types of augmented skin grafts, with examples of each. These include preliminarily augmented grafts with a dermal biomatrix, simultaneous augmentation with a perichondrocutaneous pseudo-composite graft, and delayed augmentation with staged structural grafting. Conclusions and Relevance: Augmented skin grafts represent unique methods of reconstruction for complex wounds in cosmetically sensitive areas. We propose these techniques as an evolving unique rung in the reconstructive ladder.

Composite Chondromucosal Nasoseptal Flap for Reconstruction of Suprasellar Defects.

BACKGROUND: The pedicled nasoseptal flap (NSF) is the mainstay for endoscopic skull base reconstruction. We present a novel technique using a semirigid chondromucosal NSF that improves the reinforcement and protection of intracranial structures. METHODS: Composite NSFs were performed to repair intraoperative high-flow cerebrospinal fluid leaks in 2 patients who had undergone endoscopic endonasal resection of a suprasellar mass. The surgical technique and postoperative outcomes are described. RESULTS: The flaps were sufficient for defect coverage, and the patients did not experience any cerebrospinal fluid leak in the immediate and delayed postoperative periods. No complications related to the composite flap had developed. CONCLUSIONS: The composite chondromucosal NSF is a reliable reconstruction option for select ventral cranial base reconstruction cases with the potential to improve the protection of intracranial structures. Additional surgical cases and longer follow-up are required for a better assessment of long-term outcomes.

Composite Cartilage-osseous-mucosal Nasoseptal Flap for Reconstruction after Near Total Rhinectomy.

BACKGROUND: Reconstruction of full thickness nasal defects usually requires different donor sites for the external skin envelope, structural elements, and internal nasal lining. In this paper we present a novel single site method for dual inner lining and skeleton repair for full thickness nasal defects with a composite nasoseptal flap and extended pedicle dissection. METHODS: A 72-year-old male presented with a T4b melanoma involving the nasal dorsum and left upper lateral cartilage. Following full thickness resection, reconstruction was performed with a nasoseptal flap (NSF) with attached septal cartilage and vomer in conjunction with a paramedian forehead flap. Extended pedicle dissection into the pterygopalatine fossa allowed the NSF to fully cover the defect. RESULTS: The nasal defect was fully corrected. There was no evidence of flap compromise or nasal valve stenosis at 1 month, 2 month, and 1 year follow-up visits. CONCLUSIONS: We present here the first successful application of a composite cartilage-osseous-mucosal NSF for multilayered nasal reconstruction. In appropriate patients, this technique may obviate the need for flaps or grafts from extranasal sources, limiting donor site morbidity.

Endoscopic Endonasal Reconstruction of High-Flow Cerebrospinal Fluid Leak with Fascia Lata "Button" Graft and Nasoseptal Flap: Surgical Technique and Case Series.

Background The endoscopic endonasal approach (EEA) has become increasingly used for resection of skull base tumors in the sellar and suprasellar regions. A nasoseptal flap (NSF) is routinely used for anterior skull base reconstruction; however, there are numerous additional allografts and autografts being used in conjunction with the NSF. The role of perioperative cerebrospinal fluid (CSF) diversion is also unclear. Objective This study was aimed to analyze success of high-flow CSF leak repair during EEA procedures without use of CSF diversion through lumbar drainage. Methods A retrospective chart review of patients who had intraoperative high-flow CSF leak during EEA procedures at our institution between January 2013 and December 2017 was performed. CSF leaks were repaired with use of a fascia lata button graft and nasoseptal flap, without use of perioperative lumbar drains. Results A total of 38 patients were identified (10 male, 28 female). Patient BMIs ranged from 19.7 to 49 kg/m 2 (median = 31 kg/m 2 ), with 18 patients meeting criteria for obesity (BMI > 30 kg/m 2 ) and 12 patients overweight (25 kg/m 2 < BMI < 29.9 kg/m 2 ). There was no incidence of postoperative CSF leak. Conclusion In our experience, the nasoseptal flap used in conjunction with the fascia lata button graft is a safe, effective and robust combination for cranial base reconstruction with high-flow intraoperative CSF leaks, without need for lumbar drains.

Lengthening the nasoseptal flap pedicle with extended dissection into the pterygopalatine fossa.

OBJECTIVES/HYPOTHESIS: Releasing the nasoseptal flap (NSF) pedicle from the sphenopalatine artery (SPA) foramen may considerably improve flap reach and surface area. Our objectives were quantify increases in pedicle length and NSF reach through extended pedicle dissection into the pterygopalatine fossa (PPF) through cadaveric dissections and present clinical applications. STUDY DESIGN: Anatomical study and retrospective clinical cohort study. METHODS: Twelve cadaveric dissections were performed. Following standard NSF harvest, the distance from the anterior edge of the flap to the anterior nasal spine while pulling the flap anteriorly was measured. As dissection into the SPA foramen and PPF continued, similar interval measurements were completed in four stages after release from the SPA foramen, release of the internal maxillary artery (IMAX), and transection of the descending palatine artery (DPA). The extended pedicle dissection technique was performed in seven consecutive patients for a variety of different pathologies. RESULTS: The mean length of the NSF from the anterior nasal spine and maximum flap reach were 1.91 ± 0.40 cm/9.3 ± 0.39 cm following standard harvest, 2.52 ± 0.61 cm/9.75±1.06 cm following SPA foramen release, 4.93 ± 0.89 cm/12.16 ± 0.54 cm following full IMAX dissection, and 6.18 ± 0.68 cm/13.41 ± 0.75 cm following DPA transection. No flap dehiscence or necrosis was observed in all seven surgical patients. CONCLUSIONS: Extended pedicle dissection of the NSF to the SPA/IMAX markedly improves the potential length and reach of the flap. This technique may provide a feasible option for reconstruction of large anterior skull base and craniocervical junction defects. Seven successful cases are presented here, but further studies with larger series are warranted to validate findings in a clinical setting. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:18-24, 2020.

Experimental and theoretical evaluation of a fiber-optic approach for optical property measurement in layered epithelial tissue.

Improvements in measurement of epithelial tissue optical properties (OPs) in the ultraviolet and visible (UV-Vis) may lead to enhanced understanding of optical techniques for neoplasia detection. In this study, we investigated an approach based on fiber-optic measurement of reflectance to determine absorption and reduced scattering coefficients (µ(a) and µ(s)') in two-layer turbid media. Neural network inverse models were trained on simulation data for a wide variety of OP combinations (µ(a) = 1-22.5, µ(s)' = 5-42.5 cm(-1)). Experimental measurements of phantoms with top-layer thicknesses (D) ranging from 0.22 to 0.66 mm were performed at three UV-Vis wavelengths. OP estimation accuracy was calculated and compared to theoretical results. Mean prediction errors were strongly correlated with D and ranged widely, from 1.5 to 12.1 cm(-1). Theoretical analyses indicated the potential for improving accuracy with alternate probe geometries. Although numerous challenges remain, this initial experimental study of an unconstrained approach for fiber-optic-based OP determination in two-layer epithelial tissue indicates the potential to provide useful measurements.
