The 10-Item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) for Functional and Cosmetic Rhinoplasty.

ABSTRACT:

Importance

Rhinoplasty is a common operation in which shape and function are intimately related, whether the procedure is cosmetic, functional, or combined in nature. There is currently no properly developed and validated patient-reported outcome measure (PROM) to evaluate both functional and cosmetic components of rhinoplasty.

Objective

To develop, validate, and field test the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) to evaluate both functional and cosmetic outcomes of rhinoplasty.

Design, setting, and participants

Survey development study between October 2016 and April 2017 in a tertiary referral facial plastic and reconstructive surgery clinic. Preoperative and postoperative adult patients undergoing rhinoplasty, whether cosmetic or reconstructive, were included. A fifth group of adult nonrhinoplasty patients (facial cosmetic or reconstructive) were also included for the field test.

Main outcomes and measures

Generated and reduced items, psychometric validation measures of the SCHNOS, and differences on scales between groups.

Results

For survey development, a total of 18 patients and 5 experts were interviewed. Of these patients, 5 were male, and 13 were female. Their mean (SD) age was 38 (14.8) years (range, 20-64 years). Field testing included 191 patients (67% were women and the mean [SD] age was 41.5 [15.8] years). A total of 10 items were included after generation, cognitive interviews, and item reduction. The 10 items represent 2 domains: nasal obstruction (first 4 items) and nasal cosmesis (last 6 items). For both domains, Cronbach ? was excellent: 0.94 (95% CI, 0.92-0.95) for obstruction and 0.94 (95% CI, 0.93-0.95) for cosmesis. Exploratory factor analysis using scree plots for each domain showed that the domains are unidimensional in nature with each domain evaluating what it is intended to assess (nasal obstruction and cosmesis). The factor loading estimates were high for all the items, varying from 0.74 to 0.92. Kruskal-Wallis testing showed a significance level of P?Conclusions and relevanceWe have developed and validated a new PROM to evaluate both functional and cosmetic rhinoplasty patients. The domains of obstruction and cosmesis were found to be internally consistent and unidimensional. The SCHNOS provides a short, validated questionnaire that we recommend for use in all functional or cosmetic rhinoplasty patients.

Project description:ImportanceThe social perception of nasal dorsal modification for male rhinoplasty is poorly understood.ObjectiveTo investigate the association of modifying the male nasal dorsum with the perception of such social attributes as youth, approachability, healthiness, masculinity/femininity, intelligence, successfulness, and leadership.Design, setting, and participantsUsing computer simulation software, 12 images with varied combinations of the nasal dorsal shape, nasofrontal angle (NFA), and nasolabial angle (NLA) were generated from a photograph of a male volunteer's face in profile. These photographs were then sent to participants at a university clinic who were English-speaking adult internet users who were masked to the purpose of the study, which asked them to value different social attributes regarding the face in the photograph in a 16-question survey. The study was conducted in September 2018 and the data were analyzed thereafter until March 2019.ExposuresTwelve photographs embedded in a 16-question survey.Main outcomes and measuresPopulation proportions of responses and χ2 test and graphical analysis based on 95% confidence intervals.ResultsOf 503 respondents (survey provision rate, 100%), 412 (81.9%) were women, 386 (76.7%) were white, 32 (6.4%) were Hispanic or Latinx, 63 (12.5%) were black/African American, 10 (2.0%) were Asian/Pacific Islander, and the median age was 46 years (interquartile range, 32-61 years). The man with ski slope-shaped nose with an NFA of 130° and NLA of 97° was often associated with frequently perceived positive characteristics; specifically, he was judged to be the most attractive (95% CI, 18%-26%; P < .001). Participants also often associated superlative youth (95% CI, 15%-24%; P < .001), approachability (95% CI, 13%-20%; P = .002), and femininity (95% CI, 14%-22%; P < .001) with dorsal contours that did not feature a dorsal hump. The man with a dorsal hump-shaped nose with an NFA of 140° and NLA of 105° was associated by the highest proportion of participants with being the oldest (95% CI, 35%-44%; P < .001), least approachable (95% CI, 27%-35%; P < .001), least attractive (95% CI, 37%-42%; P < .001), and least healthy (95% CI, 26%-34%; P < .001). Subset analyses also revealed statistically significant dorsal contour preferences by observers' age, gender, and race/ethnicity.Conclusions and relevanceA reduced dorsal slope combined with more acute NFAs and NLAs was associated with positively perceived social attributes. The results may be of interest to rhinoplasty surgeons and their male patients when planning changes to the nasal dorsal contour.Level of evidenceNA.

Project description:Autologous cartilages or synthetic nasal implants have been utilized in augmentative rhinoplasty to reconstruct the nasal shape for therapeutic and cosmetic purposes. Autologous cartilage is considered to be an ideal graft, but has drawbacks, such as limited cartilage source, requirements of additional surgery for obtaining autologous cartilage, and donor site morbidity. In contrast, synthetic nasal implants are abundantly available but have low biocompatibility than the autologous cartilages. Moreover, the currently used nasal cartilage grafts involve additional reshaping processes, by meticulous manual carving during surgery to fit the diverse nose shape of each patient. The final shapes of the manually tailored implants are highly dependent on the surgeons' proficiency and often result in patient dissatisfaction and even undesired separation of the implant. This study describes a new process of rhinoplasty, which integrates three-dimensional printing and tissue engineering approaches. We established a serial procedure based on computer-aided design to generate a three-dimensional model of customized nasal implant, and the model was fabricated through three-dimensional printing. An engineered nasal cartilage implant was generated by injecting cartilage-derived hydrogel containing human adipose-derived stem cells into the implant containing the octahedral interior architecture. We observed remarkable expression levels of chondrogenic markers from the human adipose-derived stem cells grown in the engineered nasal cartilage with the cartilage-derived hydrogel. In addition, the engineered nasal cartilage, which was implanted into mouse subcutaneous region, exhibited maintenance of the exquisite shape and structure, and striking formation of the cartilaginous tissues for 12 weeks. We expect that the developed process, which combines computer-aided design, three-dimensional printing, and tissue-derived hydrogel, would be beneficial in generating implants of other types of tissue.

Project description:ImportanceSignificant nasal septal deviation may require complex reconstruction to achieve complete correction. Subtotal septal reconstruction is a method for addressing deviations in the L-strut.ObjectivesTo review the long-term outcomes of subtotal septal reconstruction and provide objective evidence of functional and aesthetic improvement.Design, setting, and participantsThis medical record review obtained data on 144 patients who underwent subtotal septal reconstruction from September 1, 2008, to September 1, 2013. Data analysis was performed from September 1, 2013, to September 1, 2014.Main outcomes and measuresFunctional outcomes were measured using the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, and objective aesthetic outcomes were measured using 3-dimensional (3-D) stereophotogrammetry. Follow-up times were classified as time point 1 (TP1; preoperative), time point 2 (TP2; early postoperative), and time point 3 (TP3; final postoperative).ResultsOf the 144 patients who underwent subtotal septal reconstruction, 104 (72.2%) were female; the mean (SD) age was 37.3 (13.7) years; 57 underwent primary septorhinoplasty; and 87 (60.5%) underwent revision septorhinoplasty. The NOSE scores improved in all 5 categories of nasal obstruction, with mean (SD) survey completion at 270 (260.1) days. Aesthetic results were measured with 3-D imaging after a mean (SD) follow-up of 613.5 (434.4) days postoperatively. No statistically significant loss was found in mean (SD) nasal length over time (TP2 to TP 3, -0.16 [1.36] mm; 95% CI, -0.54 to 0.22 mm; P?=?.41) or between mean (SD) postoperative loss of projection (TP2 and TP3, -0.19 [0.92] mm, 95% CI, -0.45 to 0.07 mm; P?=?.17). An increase in mean (SD) rotation (nasolabial angle) generated with septorhinoplasty (4.24° [11.08°]; 95% CI, 1.14°-7.34°; P?=?.01) and a mean (SD) decrease in rotation detected during postoperative healing (-2.63° [6.96°]; 95% CI, -4.63° to -0.63°; P?=?.01) were found. Although measurement of symmetry was improved in the early postoperative period (TP1 to TP2, -0.16 [1.26] mm; 95% CI, -0.52 to 0.20 mm; P?=?.40), this finding did not become statistically significant until the final measurement (TP1 to TP3, -0.43 [1.07] mm; 95% CI, -0.73 to -0.13 mm; P?=?.007; TP2 to TP3, -0.28 [0.87] mm; 95% CI, -0.53 to -0.03 mm; P?=?.03). A mean (SD) decrease in columellar show was achieved with surgery (-0.66 [1.37] mm; 95% CI, -1.05 to -0.27 mm; P?=?.001). No statistically significant change was found in the alar-columellar association from TP2 to TP3 in this patient population, confirming no unwanted alar or columellar retraction over time (0.10 [0.61] mm; 95% CI, -0.07 to 0.27 mm; P?=?.25). A total of 114 patients (79.2%) required costal cartilage harvest for adequate reconstruction.Conclusions and relevanceSubtotal septal reconstruction yields improved functional and aesthetic outcomes and has the potential to be a useful tool for the rhinoplasty surgeon in the treatment of severe septal deviation.Level of evidence4.
