Simultaneous Rhinoplasty and Septal Perforation Repair Using the Bone-Cartilaginous Unit.

Various techniques are employed for septal perforation repair, but success rates still vary. Numerous mucosal flaps are used for septal perforation closure; however, a scaffold is essential for proper positioning and enhanced mucosal growth. To assess the effectiveness of using a septal bone/cartilage composite graft (BC unit) to close septal perforations in rhinoplasty patients and evaluate patient satisfaction. This case series included patients with septal perforation undergoing rhinoplasty and perforation repair from 2019 to 2023. BC units were used to cover the cartilaginous perforations in all patients. Patients were followed for a minimum of one year, assessing surgical results and postoperative satisfaction using the 10-Item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). In this study, 31 patients (22 female, 9 male) aged 34.80 ± 10.31 years (19-59 years) were enrolled. Nine had prior septoplasty, while four had undergone septorhinoplasty. The preoperative perforation size ranged from 6 to 27 mm (mean 14.1 mm). At final follow-up, 26 cases (83.8%) achieved complete closure, while three had incomplete closures, and two experienced reperforation. Analysis revealed a notable mean decrease of 31.93 (SD = 26.47) in obstruction domain scores (SCHNOS-O) and a mean decrease of 44.19 (SD = 25.37) in cosmesis domain scores (SCHNOS-C). Septal perforation repair and rhinoplasty can be safely and effectively performed concurrently using BC units for suitable candidates.

Dorsal preservation rhinoplasty versus dorsal hump reduction: a randomized prospective study, functional and aesthetic outcomes.

To compare the functional and esthetic outcomes of dorsal preservation rhinoplasty (DPR) and conventional dorsal hump reduction (DHR) in primary rhinoplasty using patient-reported outcome measures (PROMs) and cone beam computed tomography (CBCT). In our randomized prospective double-blinded clinical trial, 50 patients had dorsal nasal hump surgery between October 2021 and November 2022 in our tertiary referral center. All surgeries were done by the same surgeon. Patients were randomly assigned to two groups: Group (A): 25 patients had DPR, and group (B): 25 patients underwent DHR. Pre-operative and post-operative evaluations were conducted using standardized cosmesis and health nasal outcomes survey (SCHNOS), surgeons' rhinoplasty evaluation questionnaire (SREQ), and the CBCT. Following an average of 7.22 ± 2.07 months, patients in both groups reported significantly higher levels of satisfaction, as measured by the SCHNOS score (p < 0.001) and the average of three SREQ scores (p < 0.001). These results align with the radiological analysis, which denoted an overall improvement in the average of both sides' internal nasal valve angle and cross-sectional area after surgery with (p = 0.001) and (p = 0.085), respectively, for the DPR group and with (p = 0.281) and (p = 0.014), respectively, for the DHR group. There was no statistically significant difference in outcomes between both groups (p > 0.05). Dorsal preservation is a viable alternative to conventional dorsal hump reduction in primary rhinoplasty. There was no difference in the functional and esthetic outcomes between both techniques, which were verified by radiological investigation.

Outcome Evaluation of Reconstructive Septorhinoplasty in Patients with a History of Nasal Skin Necrosis.

Background: Nasal skin necrosis represents a severe rhinoplasty complication, potentially leading to nasal deformity and psychological distress. Objectives: To assess the safety, nasal function enhancement, and esthetic satisfaction in individuals with a history of nasal skin necrosis following reconstructive septorhinoplasty using patient-reported outcome measures. Methods: The case series included patients who underwent reconstructive septorhinoplasty 1 year after experiencing skin necrosis. Skeletal reconstruction was performed with an open approach using various autografts and techniques. The data collected encompassed demographics, medical history, operative reports, and postoperative events. The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) was administered preoperatively and 1 year postoperatively. Results: Most patients were female (35/38, 92%), with median age of 33.5 years (17-57) and 2 prior rhinoplasties (1-5) by 1 surgeon (1-2). The follow-up median was 23.78 months (11.83-54.23). Necrosis predominantly affected the nasal tip and soft tissue triangles. Septorhinoplasty utilized 11 V-shaped columellar base and 27 mid-columella incisions, lasting on average 274 min (175-405). Septal grafts were adequate for reconstruction in only three cases. Autografts for reconstruction encompassed auricular cartilage (31), rib cartilage (22), temporal fascia (14), and rectus fascia (6). SCHNOS scores improved significantly, with the obstruction domain decreasing from a preoperative mean of 75.92 (±22.83) to 34.08 (±27.87) and the cosmesis domain from 85.43 (±19.06) to 39.73 (±23.77). No postoperative severe vascular complication occurred. More previous surgeries linked to decreased patient satisfaction. Conclusion: Reconstructive septorhinoplasty can be successful in restoring relatively normal nasal contour following prior soft tissue necrosis, with limited risk for complications.

Translation, cultural adaptation, and validation of the Standardized Cosmesis and Health Nasal Outcomes Survey in Japanese (J-SCHNOS)

Rhinoplasty is one of the most popular plastic surgery techniques. The evaluation of both functional and cosmetic aspects of rhinoplasty is essential for planning and assessing surgery results. The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a validated questionnaire used to assess both functional and aesthetic symptoms in patients with nasal problems, and it has been translated into several languages. The purpose of this study was to translate, culturally adapt, and validate the SCHNOS in Japanese among patients undergoing rhinoplasty. This was a prospective validation study of the Japanese version of the SCHNOS (J-SCHNOS). The first phase involved translation and cross-cultural adaptation of the SCHNOS. The second phase included validation of the J-SCHNOS among native Japanese speakers. In total, 357 participants completed the final version of the J-SCHNOS (219 males and 138 females; mean age 43.4 years). The J-SCHNOS showed high internal consistency with excellent Cronbach's alpha values for both obstruction (SCHNOS-O) (0.96) and cosmetic (SCHNOS-C) (0.93) domains. The reproducibility was high, with an excellent intraclass correlation coefficient (ICC) >0.9 for all items. Exploratory factor analysis showed unidimensional structures in both the SCHNOS-O and the SCHNOS-C. The J-SCHNOS is a reliable and valid tool to assess the severity of nasal problems in patients undergoing rhinoplasty.

VALIDATION OF THE KURDISH LANGUAGE VERSION OF THE STANDARDIZED COSMESIS AND NASAL OUTCOMES SURVEY (SCHNOS), APPLICATION FOR SEPTORHINOPLASTY HEALTH

Background The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) questionnaire is a recent tool for evaluating patient satisfaction in both functional and cosmetic components of rhinoplasty. It is a reliable, steady, and corroborated patient-reported outcome measure that is not available in Kurdish.&#x0D; Objectives To evaluate the application of the Kurdish version of the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) scale for Septorhinoplasty surgery and research.&#x0D; Materials and Methodsconducted four centre studies to validate The Kurdish version of the scale We adhered to a strict translation procedure, including a forward and back translation and reconciliation interviews, to ensure the original content and concepts were preserved compared for patients and control groups and tailored to the demographic the instrument was intended for.&#x0D; Resultsshowed that the Kurdish version of the SCHNOS was conceptually comparable to the original English version and demonstrated high internal consistency for nasal function as an aesthetic postoperative outcome. The Spearman rank correlation analysis indicated a weak to moderate correlation between the different items, indicating that the different items measure somewhat distinct aspects of nasal function and appearance. However, the high Cronbach’s alpha values suggested that the different items measure similar aspects of nasal function and appearance and can be considered a reliable scale for assessing SCHNOSE.The results of the paired samples t-test showed significant differences between the preoperative and postoperative obstructive and aesthetic SCHNOSE scores, indicating that the observed differences are likely to be real and not simply due to random variation in the data.&#x0D; ConclusionThe Kurdish form of the SCHNOS demonstrates virtuous reliability and validity, coherent with the original version. Thus, it can be used as a validated questionnaire for outcome measurements for rhinoplasty. This version should be recommended to evaluate both functional and cosmetic outcomes in daily practice and rhinoplasty-related examinations.

Functional and Aesthetic Outcomes of Asymmetric Dorsal Preservation for Correction of I-Shaped Crooked Nose Deformity.

The study was designed to evaluate the effectiveness of the asymmetric dorsal preservation technique for correcting I-shaped crooked nose deformity (CND). Patients with I-shaped CND who underwent asymmetric dorsal preservation in the period from September 2020 to September 2021 were included in this retrospective study. The Rhinomanometry and Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) was used to assess the outcomes. Deviation angle (DA) measurements were used to evaluate the degree of crookedness. The results were recorded both preoperatively and 12 months postoperatively. Twenty-three patients were included in the study. Total nasal airflow and long-side nasal airflow were significantly higher 12 months postoperatively (p=0.001 each). Total nasal resistance, long-side nasal resistance, SCHNOS scores and DA measurements were significantly lower 12 months postoperatively (p<0.001 each). Asymmetric dorsal preservation is a successful alternative technique for correcting I-shaped CND and achieving optimal aesthetic and functional outcomes.

Patient Outcomes in Lateral Crural Repositioning and Reconstruction in Revision Rhinoplasty.

Background: In revision rhinoplasty, lateral crural repositioning/reconstruction is considered a complex maneuver. The aim of this study is to measure patient outcomes after lateral crural repositioning/reconstruction in revision rhinoplasty. Methods: In this retrospective case series, patients who underwent revision rhinoplasty with lateral crural repositioning/reconstruction for functional, cosmetic, or combined purposes were reviewed. Preoperative Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) scores, functional and cosmetic visual analog scales (VAS-functional [F] and VAS-cosmetic [C]), and lateral wall insufficiency (LWI) grades were compared with their respective postoperative scores. Results: Forty-two patients were identified who underwent lateral crural repositioning. The mean postoperative follow-up for ≤6 months (PO1) and >6 months (PO2) was 3.1 (standard deviation [SD] 1.7) and 11.5 (SD 5.3) months, respectively. At both postoperative periods, significant improvement (p < 0.05) in patient-reported outcomes was observed in mean SCHNOS-Obstruction, SCHNOS-Cosmesis, VAS-F, and VAS-C scores. The postoperative changes in LWI scores (Δ) were significant on both sides at zone 1 at PO1 (p < 0.05) and PO2 (p < 0.05), and at PO2 on the left side (p < 0.05) only, for zone 2. Conclusion: Lateral crural repositioning with reconstruction is an effective maneuver in revision rhinoplasty in a subset of patients and specifically helps to improve nasal tip aesthetics while preserving function.

Functional and Aesthetic Outcomes of No-Dissection Nasal Dorsum Using Subdorsal Septal Excision in Preservation Rhinoplasty.

Dorsal preservation (DP) caused privilege change in the concept of rhinoplasty and a promising superior functional and aesthetic transformation in rhinoplasty surgery. Avoiding dissection of the dorsal nasal bone and cartilage will leave the soft-tissue envelope intact, leading to a fine and smooth appearance, faster operation with less subsequent edema, and overall preservation of the dorsal aesthetic line. This prospective study included 113 patients who underwent DP rhinoplasty for nasal hump treatment with minimum dissection of nasal dorsum soft-tissue envelope. Results were evaluated using the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). The mean preoperative SCHNOS score was 7.21; the mean obstructive score was 2.95 ± 1.068 and the mean aesthetic score was 4.27 ± 0.771. The average lowering of the dorsal hump was 4.4 mm. Approximately 96% of patients showed improvement in the SCHNOS score after surgery, 86.7% (98 patients) showed improvement in the obstructive symptoms and 95.6% (108 patients) showed improvement in the aesthetic score. Complications were seen in 22.11% (most commonly residual hump in 13.27% of cases and dorsal indentation in 5.31%), bleeding was seen in 2.65%, and granuloma formation at the dorsal osteotomy site was seen in 0.88%. There was a very significant improvement in the aesthetic, obstructive, and overall SCHNOS score ( P = 0.000) for each parameter. DP rhinoplasty is a safe and very effective procedure, with very low risk of complications. Most of the treated patients have improvement of the obstructive and aesthetic outcome after surgery.

Validation of the European Portuguese Language Version of the Standardized Cosmesis and Health Nasal Outcomes Survey.

The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) questionnaire is a tool developed to evaluate functional and aesthetic components of rhinoplasty. It is a reliable patient-reported outcome measure, not available in the European Portuguese language. Our goal was to translate and culturally adapt the SCHNOS questionnaire to the European Portuguese language. The questionnaire was forward and backward translated and culturally adapted to the European Portuguese language following international guidelines. The authors evaluated internal consistency, correlation, and reproducibility to determine the validity of the questionnaire. The final European Portuguese version of the SCHNOS was administered to 58 native European Portuguese speakers. Both the SCHNOS-O (obstructive) and SCHNOS-C (cosmetic) showed high internal consistency with Cronbach's α of 0.93 and 0.95, respectively. Also, for the entire SCHNOS, Cronbach's α was 0.96. All the items demonstrated good item-test and item-rest correlations with the differences between pre- and postestimates being nonsignificant. The translation, adaption, and validation of the SCHNOS into European Portuguese were successfully performed. This provides another tool to help evaluate the functional and aesthetic outcomes of rhinoplasty patients.

Automating the Standardized Cosmesis and Health Nasal Outcomes Survey Classification with Convolutional Neural Networks.

Importance: Currently, the aesthetic appearance and structure of the nose in a rhinoplasty patient is evaluated by a surgeon, without automation. Objective: To compare the assessment of convolutional neural networks (CNNs) (machine learning) and a rhinoplasty surgeon's impression of the nose before rhinoplasty. Methods: Preoperative nasal images were scored using a modified standardized cosmesis and health nasal outcomes survey (SCHNOS) questionnaire. Artificial intelligence (AI) models based on CNNs were developed and trained to classify patient nasal aesthetics into one of five categories, representing even intervals on the SCHNOS scoring scale. The models' performances were benchmarked against expert surgeon evaluation. Results: Two hundred thirty-five preoperative patient images were included in the study. The best-performing AI model achieved 61% accuracy and 0.449 average Matthews Correlation Coefficient on new patients. Conclusions: This pilot study suggests a proof-of-concept for AI to allow an automated patient assessment tool trained on preoperative patient images with a potential utility for counseling rhinoplasty patients.

A Novel Ear Cartilage Caudal Septal Extension Graft.

In cases of weak or deficient caudal septum, the caudal septum extension graft (CSEG) is the most commonly used reconstructive method. In the current study we introduce a newly-designed conchal cartilage CSEG and evaluate its cosmetic and functional outcomes. The graft has an average length of 3 ± 0.3 cm and composed of a distal double-layered part, which is 3 to 4 mm wide and a proximal single-layered part, which is 1.2 to 1.7 cm wide. The graft design allows the proximal single-layered part to be fixed on either sides of the caudal septum while keeping the distal double-layered segment in the midline. The study included 230 patients, of which 83% were revisions, all patients completed a validated patient-reported outcome measure (PROM) questionnaire pre- and postoperatively. The PROMs used were either the Nasal Obstruction Symptom Evaluation (NOSE) survey or the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). During the mean follow-up period of 18.2 months (range: 9-192 months) no serious complications were encountered and only six cases (2.3%) required minor revisions of the CSEG.Using the proposed conchal cartilage, CSEG resulted in an improved cosmetic and functional outcome as evidenced by the significant postoperative improvement in the NOSE, SCHNOS-O, and SCHNOS-C scores with a p-value <0.001, <0.05, and <0.0001, respectively. The graft provided adequate tensile strength and support to the nasal tip, which resulted in improved tip projection, rotation, definition, and symmetry, while maintaining a degree of flexibility and elasticity which is much more than that of the rib or even the septum thus resulting in the most natural feel of the nasal tip lobule.

Comparison of Dorsal Preservation and Dorsal Reduction Rhinoplasty: Analysis of Nasal Patency and Aesthetic Outcomes by Rhinomanometry, NOSE and SCHNOS Scales.

Dorsal preservation techniques have been preferred and gained popularity in recent years. The current study compares the effects of dorsal preservation and dorsal reduction rhinoplasty on nasal patency and aesthetic outcomes by using Patient-Reported Outcome Measures (PROMs) and rhinomanometry. To our knowledge, this is the first study to compare dorsal preservation and dorsal reduction techniques with rhinomanometry. This is a prospective study of 34 patients who underwent rhinoplasty between January 2021-June 2022. The patients were randomly selected preoperatively and divided into two groups as structural rhinoplasty (SR) and preservation rhinoplasty (PR). Nasal Obstruction and Symptom Evaluation (NOSE), Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) scales and rhinomanometric evaluation were performed preoperatively, at 3rd month and 12th month postoperatively. Nineteen patients (10 female, 9 male) were in SR group, 15 patients (7 female, 8 male) were in PR group. There was not significant difference in terms of age and gender between groups. In both groups, NOSE, SCHNOS-O and SCHNOS-C results were found to be significantly lower at postoperative 3rd and 12th month compared to preoperatively (p < 0.001 for the entire SR group, p = 0.001 for the entire PR group). There was no significant difference between groups in terms of PROMs. Mean total nasal volume (TNV) at 12th month were statistically higher than preoperative value in PR group (p = 0.031). Also there was no significant difference in SR group and between groups in terms of rhinomanometry results. Dorsal preservation with pushdown technique provides good functional and aesthetic results comparable with structural rhinoplasty.

Functional and Aesthetic Outcomes of Let Down Dorsal Preservation Rhinoplasty.

Background: Preservation rhinoplasty is a re-emerging technique that lacks data on functional and aesthetic outcomes. Objective: To measure the change in patient-reported nasal aesthetic perception, nasal breathing, and sleep and compare outcomes between two different septal cartilage manipulation techniques among patients undergoing preservation rhinoplasty. Methods: Functional and aesthetic outcomes of a let down dorsal preservation rhinoplasty using either the modified subdorsal strip method (MSSM) or subdorsal Z-flap are assessed pre- and postoperatively using the validated assessment tools Nose Obstruction Symptom Evaluation (NOSE), Sinonasal Outcome Test (SNOT-22), Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS), and Epworth Sleepiness Scale (ESS). Results: Fifty-two patients, 40 women and 12 men ages 15-69 years, underwent dorsal preservation rhinoplasty and the majority reported at 1, 3, 6, and 12 months postoperatively significant improvement based on a paired t-test in NOSE, SNOT-22, SCHNOS, and ESS scores except for ESS scores at 6 and 12 months. No significant difference based on a two-sample t-test was observed between the MSSM and Z-flap techniques implemented. Conclusion: Let down dorsal preservation rhinoplasty with either the MSSM or Z-flap cartilage manipulation technique can achieve significant improvement in nasal aesthetics, nasal breathing, and sleep according to patient responses on validated assessment tools.

Patient's Perception of Nasal Function and Cosmesis After Maxillomandibular Advancement for Obstructive Sleep Apnea.

Background: Maxillomandibular advancement (MMA) remains one of the most effective surgeries for the treatment of obstructive sleep apnea (OSA), but it can be difficult to manage nasal and midfacial esthetics for patients requiring significant maxillary advancement. Objective: To evaluate changes in the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) after the modified MMA approach. Methods: This prospective study was conducted on subjects undergoing MMA at a tertiary referral center from September 2020 to August 2021. Nasal function, cosmesis, and sleepiness were assessed perioperatively with the SCHNOS, visual analog scale for nasal function and cosmesis, and Epworth sleepiness scale (ESS). Objective polysomnography data were also investigated. Results: Thirty-one subjects met inclusion criteria. After MMA, SCHNOS-O (obstruction domain) improved from 44.38 ± 26.21 to 19.03 ± -4.75 (p < 0.001). The SCHNOS-C (cosmesis domain) improved significantly from 13.95 ± 19.32 to 5.27 ± 8.93 (p = 0.029). Specific items evaluating self-esteem, nasal straightness, and symmetry showed significant improvement (p = 0.006, 0.025, 0.044). The ESS also improved from 9.41 ± 6.11 to 3.26 ± 3.03 (p < 0.001), and it correlated with nasal obstruction scores. Conclusion: In this study, patients' perception of nasal obstruction and appearance improved after applying the nasal modifications to MMA described for OSA.

Translation, Cultural Adaptation and Validation of the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) in Italian.

Rhinoplasty necessarily concerns functional and cosmetic aspects, and outcomes of both should be assessed in each patient. There has been a lack in the literature in Italian for a comprehensive tool for assessing both aspects of rhinoplasty. The objective is to translate and validate the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) into Italian. Forward and back-translation was used. Content validity was evaluated by experts and by patient interviews. Internal consistency was assessed by a Cronbach's alpha. The structure validity was assessed by an exploratory factor analysis. Cognitive interviews of 10 rhinoplasty patients resulted in a good overall comprehension of the SCHNOS. Of the 411 respondents, 281 (32%) were women, and the average age was 33.6 (11.3) years. The alpha was excellent for both the obstruction domain (SCHNOS-O) (0.90) and the cosmetic domain (SCHNOS-C) (0.94). All the correlations between repeated measures were moderate to very strong. The exploratory factor analysis demonstrated unidimensionality of both the SCHNOS-O and the SCHNOS-C scores. The SCHNOS was successfully translated and validated in Italian and can be recommended for a clinical use among rhinoplasty patients.

Comparison of the Distribution of Standardized Cosmesis and Health Nasal Outcomes Survey Scores Between Symptomatic and Asymptomatic Patients.

Background: The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a validated patient-reported outcome measure that evaluates subjective cosmetic and functional complaints. The goal of this study was to compare scores between patients with and without nasal complaints. Methods: This is a retrospective review of SCHNOS-O (obstructive) and SCHNOS-C (cosmetic) scores in patients presenting for functional or cosmetic concerns between 2019 and 2020. Receiver operating characteristic curve analysis was used to determine the score that best separated symptomatic from asymptomatic patients. SCHNOS scores were also subdivided to define severity of presenting complaints. Results: In total, 414 patients were included. A SCHNOS-O score of 40 differentiated patients with and without nasal obstruction. Patients may be categorized as having mild (<40), moderate (45-70), and severe (75-100) nasal obstruction based on the SCHNOS-O score. A score of 30 on the SCHNOS-C differentiated patients with and without aesthetic concerns. Patients may be categorized as having mild (<33.3), moderate (33.3-66.6), and severe (>66.6) aesthetic distress based on the SCHNOS-C. Conclusion: An understanding of SCHNOS scores that differentiate symptomatic for asymptomatic patients can aid in the preoperative evaluation of rhinoplasty patients.

Functional Role of Scroll Reconstruction in Open Rhinoplasty

The scroll area of the nose is important for breathing; thereby, its reconstruction can improve the nasal patency. To evaluate the effect of scroll reconstruction on breathing in patients following open rhinoplasty. Using the prospective controlled study design, we enrolled a cohort of patients undergoing open rhinoplasty. The patients were randomly divided into two groups (each group with n = 14). The predictor variable was scroll reconstruction (yes/no). The main outcome variables include pre- and postoperative third-month peak nasal inspiratory flowmeter (PNIF) value (ml/min) and 10-Item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). Appropriate statistics were computed, and a P < 0.05 was considered significant. There was no demographic difference between both groups. Scroll reconstruction was associated with significantly improved PNIF post-surgery (P = 0.047). However, postoperative mean SCHNOS-O and SCHNOS-C was not different between the study and control groups (P = 0.58) CONCLUSIONS: This study suggests that scroll reconstruction helps improve nasal patency during forced inspiration in open rhinoplasty patients and provides a similar aesthetic outcome compared to the non-scroll-reconstructed group. Future research works should be done in a larger patient cohort. This journal requires that authors assign a level of evidence to each article.

Effect of Lateral Crural Procedures on Nasal Wall Stability and Tip Aesthetics in Rhinoplasty.

To evaluate the lateral nasal wall stability, nasal function, and cosmesis when creating an aesthetically pleasing nasal tip subunit utilizing lateral crus (LC) altering procedures. Retrospective cohort. In this retrospective cohort study, cosmetic rhinoplasty patients undergoing LC procedures with available lateral wall insufficiency (LWI) scores were included. An LWI grading system was used to evaluate internal (zone 1) and external (zone 2) nasal valves objectively. Secondarily, Nasal Obstruction Symptom Evaluation (NOSE) Score, Visual Analog Scale (VAS) and Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) results were evaluated. Based on the LC intervention, the cohort was divided into six groups: lateral cural strut graft (LCSG), mini-LCSG, lateral crural overlay (LCO) with and without additional support, cephalic trimming, and cephalic turn-in flaps. Subjects undergoing LCO with and without support, LCSG, and mini-LCSG showed significant improvement in zone 1 LWI (P = .042, P = .041, P < .001, and P < .001, respectively), while cephalic trimming and turn-in/hinged flaps had no effect. Subjects undergoing LCO with support and LCSG showed significant improvement in zone 2 LWI (P = .022, P = .004), while LCO without support, mini-LCSG, cephalic trimming, and turn-in flaps showed no effect on LWI. The SCHNOS-C and VAS-C showed significant improvement in all subgroups (P < .05) when comparing pre- to postoperative values. Alar-spanning sutures did not significantly change zone 1 scores but did conceal zone 2 improvements in LCSG and LCO with support groups. Selected LC procedures are robust techniques for improving tip cosmesis independently without compromising nasal lateral wall stability. Some LC procedures can improve nasal valves patency in tip surgery. Laryngoscope, 131:E1830-E1837, 2021.

Application of Conchal Cartilage Grafts in Nasal Tip Plasty: Comparison and Experience of 3 Methods.

The autologous conchal cartilage of good elasticity is easy to harvest, thus is often used in nasal tip plasty of East Asians. However, the operation techniques vary a lot among different surgeons. This article aims to introduce 3 techniques commonly used in clinical practice. One hundred three patients were included in this study and divided into 3 groups according to the shape of the nasal tip during 2017 to 2019. The patients were followed up for at least 6 months. All patients were measured with Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). ImageJ software was used to measure and calculate the projection ratio for lateral position standard image, and columella-labial angle (CLA) was measured. In group 1, SCHNOS for nasal obstruction (SCHNOS-O) score were 13.23 ± 7.61 and 14.49 ± 10.55 (P > 0.05); SCHNOS for nasal cosmesis (SCHNOS-C) score were 66.55 ± 31.23 and 21.73 ± 18.91 (P < 0.001); projection ratio were 0.51 ± 0.04 and 0.57 ± 0.05 (P < 0.001); CLA were 91.02° ± 5.67° and 93.55° ± 4.64° (P > 0.05), preoperative and postoperative, respectively. In group 2, SCHNOS-O score were 16.76 ± 13.44 and 15.44 ± 9.26 (P > 0.05); SCHNOS-C score were 61.87 ± 44.14 and 19.16 ± 29.37 (P < 0.001); projection ratio were 0.50 ± 0.05 and 0.58 ± 0.03 (P < 0.001); CLA were 92.32° ± 6.39° and 94.86° ± 5.96°(P > 0.05), preoperative and postoperative, respectively. In group 3, SCHNOS-O score were 15.25 ± 7.83 and 17.73 ± 11.66 (P > 0.05); SCHNOS-C score were 52.03 ± 33.38 and 17.73 ± 11.66 (P < 0.001); projection ratio were 0.53 ± 0.05 and 0.57 ± 0.02 (P < 0.001); CLA were 91.65° ± 5.75° and 93.21° ± 5.38° (P > 0.05), preoperational and postoperational, respectively. None of these 3 techniques cause or aggravate nasal obstruction, and all of them can achieve high cosmetic satisfaction. Technique 1 and technique 2 are suitable for the patients with moderate and moderate to severe short nose that is common in East Asia, which can better increase the protrusion of the tip and length of the nose. Technique 3 is suitable for the patients with better shape of the nose, who need to slightly increase the protrusion of the nasal tip and increase the upward rotation.
