Evaluation of Nasal Conditions on Sleep: Integrating Wearable Tech in Surgical Outcomes.

Objective: The primary objective of this study was to explore and identify the impacts of nasal septum deviation and turbinate hypertrophy on respiratory function, sleep quality, and overall well-being. Additionally, the study aimed to establish the therapeutic efficacy of surgical intervention and comprehensively analyse the additional advantages of wearable sleep trackers when combined with established diagnostic techniques. Methods: A prospective cohort of 150 participants (75 with nasal septum deviation and 75 with turbinate hypertrophy) underwent surgical intervention. The NOSE scale, PSQI, SF-36, and wearable sleep tracker data were employed for pre- and post-surgical evaluations. Objective measurements, such as nasal airflow and acoustic rhinometry, were also used. Multivariate regression was utilised to identify potential predictors of post-surgical outcomes. Results: The cohort had a mean age of 41 years with evenly balanced gender distribution. Both conditions showed post-surgical improvements in respiratory function, sleep quality, and quality-of-life. Wearable sleep tracker data provided insights into REM sleep duration and interruptions during sleep. The results indicated significant disturbances in sleep patterns in individuals with nasal septum deviation before undergoing surgery. Duration of the nasal condition was found to be a significant factor in predicting outcomes. Conclusion: Nasal septum deviation and turbinate hypertrophy had a significant impact on sleep patterns, overall well-being, and respiratory function. Surgical interventions provided significant relief, and wearable sleep tracker integration provides deeper insights into sleep disorders. The study highlights the importance of early intervention and the benefit of modern technologies in clinical evaluations.

Internal structural analysis of the nasomaxillary complex in patients with skeletal class III asymmetry: A study on asymmetry patterns.

OBJECTIVES: To investigate the internal structure of the nasomaxillary complex, including the maxillary sinus, nasal cavity and nasal septum according to the facial asymmetry pattern and to evaluate its correlation with external maxillomandibular asymmetry in Class III patients based on cone-beam computerized tomography (CBCT) images. MATERIALS AND METHODS: Facial asymmetry was analysed in a total of 100 Class III patients aged 16 years or older using CBCT scans. Patients were categorized into subgroups based on asymmetry pattern. Measurements of the nasomaxillary complex were obtained from the CBCT scans, including the volume and width of the maxillary sinuses and nasal cavities on deviated and non-deviated sides, as well as the displacement of the nasal septum. Statistical analysis was performed to compare the internal nasomaxillary variables within and between groups, and regression analysis was conducted to evaluate the correlation between facial asymmetry and the internal nasomaxillary variables. RESULTS: Group comparisons showed that there were no significant differences in the volume of the maxillary sinus and nasal cavity. However, the direction and extent of nasal septum deviation, as well as the width of the nasal cavity, varied depending on the maxillary asymmetry pattern. Regression analysis indicated a correlation between nasal septum deviation and the difference in maxillary height, while the difference in nasal cavity width was correlated with the difference in maxillary width. CONCLUSION: A comprehensive evaluation of the internal nasal anatomy is vital for understanding the intricate relationship between nasal structure and maxillary growth.

Assessment of Nasal Septum Change after Le Fort I Osteotomy Using Cone Beam Computed Tomography.

Objective: Le Fort I osteotomy (LF-IO) is widely used for the correction of dentofacial deformities, which may cause changes in the postoperative nasal septum (NS). The objective of this study was to evaluate the effects of LF-IO on the NS deviation and to determine whether the NS was affected by differences in the direction of maxilla movement. Materials and Methods: A retrospective study including 57 patients who underwent LF-IO and received cone beam computed tomography (CBCT) preoperatively and 6-12 months postoperative evaluation was performed. The NS angle of each patient was measured both pre- and postoperatively in the two coronal sections (nasion and ostium levels). The patients were divided into five paired groups and calculated. Group 1 to 4 were divided depending on the differences in the direction of maxilla movement (Group 1. Impaction ≥ 5 mm vs. Impaction < 5 mm; Group 2. Anterior movement vs. Non-anterior movement; Group 3. Impaction symmetry vs. Impaction asymmetry; and Group 4. Impaction vs. Inferior repositioning). Group 5 was divided as One-piece osteotomy vs. Multi-segmental osteotomy. Results: The mean NS angles at both nasion and ostium levels of all patients were significant increased after LF-IO. However, there were no statistical significant differences of the five paired groups. Conclusions: LF-IO osteotomy influenced increasing of the NS deviation at both the nasion and ostium levels. However, differences in the direction of the maxilla movement and maxilla segmentation showed no statistically significant changes.

Correlation Analysis of Nasal Septum Deviation and Results of AI-Driven Automated 3D Cephalometric Analysis.

The nasal septum is believed to play a crucial role in the development of the craniofacial skeleton. Nasal septum deviation (NSD) is a common condition, affecting 18-65% of individuals. This study aimed to assess the prevalence of NSD and its potential association with abnormalities detected through cephalometric analysis using artificial intelligence (AI) algorithms. The study included CT scans of 120 consecutive, post-traumatic patients aged 18-30. Cephalometric analysis was performed using an AI web-based software, CephX. The automatic analysis comprised all the available cephalometric analyses. NSD was assessed using two methods: maximum deviation from an ideal non-deviated septum and septal deviation angle (SDA). The concordance of repeated manual measurements and automatic analyses was assessed. Of the 120 cases, 90 met the inclusion criteria. The AI-based cephalometric analysis provided comprehensive reports with over 100 measurements. Only the hinge axis angle (HAA) and SDA showed significant (p = 0.039) negative correlations. The rest of the cephalometric analyses showed no correlation with the NSD indicators. The analysis of the agreement between repeated manual measurements and automatic analyses showed good-to-excellent concordance, except in the case of two angular measurements: LI-N-B and Pr-N-A. The CephX AI platform showed high repeatability in automatic cephalometric analyses, demonstrating the reliability of the AI model for most cephalometric analyses.

Septochoanal Polyp on the Concave Side of the Deviated Nasal Septum.

The septochoanal polyp is one of the choanal polyps derived from the nasal septum. They rarely occur, with only a few cases reported in the English literature. The etiology is still uncertain though it is thought to be associated with inflammation. Pathological findings generally show chronic inflammatory polyps and should be differentiated from other tumors. We report a case of a 32-year-old man diagnosed with a septochoanal polyp on the concave side of the deviated nasal septum. Previous reports have not mentioned the relationship between septochoanal polyp and the direction of septal deviation. This case is a practical example when considering the potential causes of the septochoanal polyp.

Is Computed Tomography Necessary Before Septoplasty? Correlation With Physical Examination and Patient Complaints.

INTRODUCTION: Septoplasty is one of the most common surgeries performed by otorhinolaryngologists. The gold standard for the evaluation of septal deviation is anterior rhinoscopy and nasal endoscopy. Frequently, computed tomography (CT) is also performed, although the correlation between septal deviation on CT and physical examination is unclear. OBJECTIVES: To study the relationship between symptoms and physical and radiological evaluation in patients who underwent septoplasty. METHODS: A prospective study of patients with nasal obstruction and septal deviation who underwent septoplasty. Anterior rhinoscopy and nasal endoscopy were performed by the surgeon, and the CT was evaluated by a radiologist. The degree of obstruction was evaluated in three distinct septal locations. The Nasal Obstruction Symptom Evaluation (NOSE) score was used before the surgery and two months after the surgery. RESULTS: The study included 43 patients, of whom 60.5% were male, with an average age of 37.09 years (±12.56). The degree of septal deviation in the physical examination was significantly different from that observed in CT (p˂0.05). Cartilaginous or maxillary crest septal deviations >75% were more commonly recognized by physical examination, while osseous septum deviations of 25%-50% were more easily detected by CT. There was no difference between the degree of septal deviation and the preoperative NOSE. The median preoperative NOSE was 60, and the postoperative was 5, with significant improvement (p<0.05). CONCLUSION: CT doesn't appear to be useful in the evaluation of septal deviation since it is different from the findings of a physical examination and isn't associated with the NOSE score. Clinical decisions should be based on a physical examination and patient complaints.

Do nasal and nasopharyngeal obstruction and their medical-surgical deobstruction significantly influence facial divergence? A concise review of major clinical studies with meta-analysis / L'obstruction du nez et du nasopharynx et leur désobstruction médico-chirurgicale influencent-elles significativement la divergence faciale ? Une revue concise des études cliniques majeures avec méta-analyse

Introduction: The term « adenoid facies ¼ suggests a causal relationship between nasopharyngeal obstruction and facial hyperdivergence in growing subjects. The strength of this association is controversial and few « quantified ¼ values exist. Materials and methods: A rapid electronic search was conducted on PubMed and Embase to find the main cephalometric studies involving patients with nasal/nasopharyngeal obstruction compared to a control sample. A meta-analysis was carried out to quantify the effect of obstruction (1) and intervention to relieve the obstruction (2) on mandibular divergence (SN/Pmand angle), maxillo-mandibular divergence (PP/Pmand angle), inclination of the occlusal plane (SN/Poccl) and the gonial angle (ArGoMe). Results: Qualitatively, the studies' bias level ranged from moderate to high. Results were concordant about the significant effect of the obstruction on facial divergence (1) with an increase in SN/Pmand (+3.6° on average, +4.1° in children <6 years), PP/Pmand (+5.4° on average, +7.7° <6 years), ArGoMe (+3.3°) and SN/Pocc (+1.9°). Surgical interventions to remove the respiratory obstacle in children (2) generally did not normalize the direction of growth, with the exception, with a very low level of evidence, of adenoidectomies/adeno-tonsillectomies, performed at an age less than 6-8 years. Conclusion: Early detection of respiratory obstacles and postural abnormalities associated with oral breathing appears to be decisive in order to hope for management at a young age and normalization of the direction of growth. However, the effects on mandibular divergence remain limited, requiring caution, and cannot be considered a surgical indication.

Introduction: Le terme « faciès adénoïdien ¼ suggère une relation de causalité entre l'obstruction nasopharyngée et l'hyperdivergence chez le sujet en croissance. La force de cette association est controversée et peu de valeurs « chiffrées ¼ existent. Matériels et méthodes: Une recherche électronique rapide a été menée sur PubMed et Embase pour retrouver les principales études céphalométriques impliquant des patients avec obstruction nasale/nasopharyngée comparés à une population témoin. Une métanalyse a été réalisée pour quantifier l'effet de l'obstruction (1) et de la désobstruction (2) sur la divergence mandibulaire (angle SN/Pmand), la divergence maxillo-mandibulaire (angle PP/Pmand), l'inclinaison du plan occlusal (SN/Poccl) et l'angle goniaque (ArGoMe). Résultats: Qualitativement, le niveau de biais des études allait de modéré à élevé. Les résultats étaient concordants sur l'effet significatif de l'obstruction sur la divergence faciale (1) avec une augmentation de SN/Pmand (+3,6° en moyenne, +4,1° chez les enfants < 6 ans), PP/Pmand (+5,4° en moyenne, +7,7° < 6 ans), ArGoMe (+3,3°) et SN/Pocc (+1,9°). Les interventions chirurgicales pour lever l'obstacle respiratoire chez l'enfant (2) ne permettaient généralement pas une normalisation de la direction de croissance, à l'exception, avec un très faible niveau de preuve, des adénoïdectomies/adéno-amygdalectomies, réalisées à un âge inférieur à 6-8 ans. Conclusion: Le dépistage précoce des obstacles respiratoires et des anomalies posturales associées à la ventilation orale apparaît déterminant pour espérer une prise en charge en jeune âge et une normalisation de la direction de croissance. Les effets sur la divergence mandibulaire restent cependant limités, imposant la prudence et ne constituant pas une indication chirurgicale.

Temperature-controlled radiofrequency device treatment of septal swell bodies for nasal airway obstruction: An open-label, single arm multicenter study.

BACKGROUND: Nasal airway obstruction (NAO) is a highly prevalent disorder. Septal swell body (SSB) hypertrophy is an often overlooked contributor to NAO. SSB treatment may relieve symptoms of NAO. The objective of this study was to assess the clinical use of a temperature-controlled radiofrequency (TCRF) device to treat SSBs to improve symptoms in adults with NAO. METHODS: In this prospective, multicenter, open-label, single arm study, patients with severe or extreme NAO related to SSB hypertrophy received bilateral TCRF treatment in the SSB area. The primary endpoint was improvement in Nasal Obstruction Symptom Evaluation (NOSE) Scale scores from baseline to 3 months postprocedure. A subset of study patients underwent computed tomography (CT) imaging to evaluate posttreatment changes in SSB size. RESULTS: Mean NOSE Scale scores significantly improved from 73.5 (SD 14.2) at baseline to 27.9 (SD 17.2) at 3 months postprocedure, a reduction of -45.3 (SD 21.4, 95% confidence interval [CI]: -50.4 to -40.1; p < 0.0001); the responder rate was 95.7% (95% CI: 0.88 to 0.99; p < 0.0001). CT evaluation at 3 months showed statistically significant reductions in the SSB with the greatest reduction in the middle thickness (mean change -3.4 [SD 1.8] mL, 95% CI: -4.0 to -2.8; p < 0.0001). Minimal adverse events with any relationship to the device or procedure were reported; none were serious in nature and no septal perforations occurred. CONCLUSIONS: This study demonstrates that TCRF treatment of SSB hypertrophy is well tolerated and effective at reducing both SSB size and symptoms of NAO at 3 months posttreatment.

Throat Symptoms Before and After Septal Surgery in Adults With Nasal Septum Deviation.

OBJECTIVE: To investigate subjective throat symptoms with the Qualities of Sore Throat Index (QuaSTI) in adults with nasal septum deviation. STUDY DESIGN: Prospective study. SETTING: Baskent University Ankara Hospital. METHODS: Group 1 included patients with septum deviation. Preoperative data were obtained through evaluation of subjective nasal obstruction with the NOSE (Nasal Obstruction Symptom Evaluation) and throat symptoms with the QuaSTI (group 1a). After 3 months, the same patient group was reevaluated with the NOSE and QuaSTI to obtain postoperative data (group 1b). Group 2 was formed of healthy volunteers with no nasal obstruction. RESULTS: The mean ± SD and median (range) values of the QuaSTI total score were 33.39 ± 29.50 and 18.5 (0-90) in group 1a, 7.49 ± 4.31 and 7 (0-18) in group 2, and 7.58 ± 9.24 and 4.50 (0-49) in group 1b (group 1a vs 2, P < .001; group 1a vs 1b, P < .0001). A significant difference was determined between groups 1a and 2 with respect to the QuaSTI sensory score (26.58 ± 23.54 and 18 [0-73] vs 6.51 ± 3.58 and 7 [0-15], P < .001, respectively) and between groups 1a and 1b for the QuaSTI functional score (6.03 ± 6.62 and 3 [0-20] vs 1.50 ± 2.47 and 0.50 [0-13], P = .004). No significant difference was found between groups 1a and 2 in terms of the QuaSTI emotional score (P = .126). CONCLUSION: Various persistent sensory and functional throat symptoms can be seen in patients experiencing nasal obstruction associated with septum deviation, and the majority of these symptoms recover after septal surgery.

Effects of nasal septum deviation and concha bullosa surgery on the frequency and financial burden of acute rhinosinusitis.

BACKGROUND: Nasal septum deviation/concha bullosa (DNS)/(CB) are known to be predisposing factors in the pathophysiology of acute rhinosinusitis (ARS). However, the effects of surgical treatment of these pathologies on ARS have not been adequately investigated. AIMS: To reveal the effects of the surgical treatment of DNS and CB on the frequency of the ARS, the use of antibiotics (ABs), and the direct cost incurred. METHODS: Medical records of the patients who had undergone successful surgery for DNS/CB and were diagnosed with ARS in the preoperative and postoperative 3-year period were retrospectively analyzed. The average annual number of ARS examinations of the patients, the number of ABs prescribed, and prescription, examination, and total health system costs were compared. RESULTS: Fifty-three patients (33 men (62%) and 20 women (38%)) were included in the study. There was a statistically significant decrease in the mean annual number of examinations for ARS, the number of ABs prescribed, prescription, examination, and total health system costs (p < 0.05) in the postoperative period compared with the preoperative period. CONCLUSIONS: The present study determined that successful surgeries performed in patients with DNS/CB resulted in a significant decrease in the average annual number of examinations performed for ARS, number of AB prescriptions, and prescription, examination, and total health system costs. With these results, it seems beneficial to direct patients to surgery within the framework of the health policies of countries to reduce the frequency and financial burden of ARS in DNS/CB patients.

Nasal Septal Deviation: A Comprehensive Narrative Review.

The nasal septum is an osteocartilaginous wall that divides the nose into two nasal cavities. Asymptomatic minor deviation of the septum is considered a normal developmental variation found in the majority of the population. The reported global prevalence rates had great variation due to the extent of deviation considered in the reporting studies. Previous classification systems have been proposed to classify the nasal septal deviation according to the characteristics of the nasal septum seen horizontally and vertically. For some patients, the degree of the deviation may affect the nasal airflow causing obstruction or impairing the olfactory function. Headache, rhinosinusitis, high blood pressure, obstructive sleep apnea, and breathing sounds are also among the clinical presentations of nasal septal deviation. Clinical assessment is sufficient to make the diagnosis while imaging techniques are required for decision-making. Radiological imaging techniques such as computed tomography (CT) are used to classify and assess the severity of the deviated septum. Surgical correction is the treatment option for nasal septal deviation. Septoplasty is the most common procedure used for nasal correction with high satisfaction levels and low complication rates. In this review, we present a comprehensive summary of the concept, presentation, diagnosis, management options, and quality of life of patients with nasal septal deviation.

Nasal Septum Changes in Adolescents Treated with Tooth-Borne and Bone-Borne Rapid Maxillary Expansion: A CBCT Retrospective Study Using Skeletal Tortuosity Ratio and Deviation Analysis.

Background: Using three-dimensional (3D) images, this study evaluated the impact of Rapid Maxillary Expansion (RME) on changes in Nasal Septal Deviation (NSD). Methods: Cone-beam computed tomography (CBCT) scan of 40 children with transverse maxillary deficiency, who received tooth-borne (TB) RME or bone-borne (BB) RME, were included in this investigation. Two CBCT scans were performed: one before to appliance installation (T0) and one after a 6-month retention period (T1). The analysis was performed by dividing the actual length of the septum by the desired length in the mid-sagittal plane to measure NSD based on the tortuosity ratio (TR). Results: Subjects in the TB group showed a statistically significant reduction (p < 0.05) of the TR value from T0 to T1, according to the paired Student t test. Subjects in the BB group showed similar findings, with a statistically significant reduction (p < 0.05) of the TR value from T0. No statistically significant differences were found between the mean changes of TR between TB group and BB group. Conclusions: RME may have some effects in reducing the degree of NSD; however, no differences were found between RME performed with TB and BB anchorage systems.

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation / Efeito da septoplastia no desempenho miocárdico ventricular esquerdo em pacientes com desvio de septo nasal

Abstract Introduction: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not well known. The myocardial performance index is an easy-to-apply and reliable parameter that reflects systolic and diastolic cardiac functions. Objective: The present study aimed to investigate the effect of nasal septoplasty on the myocardial performance index in patients with nasal septal deviation. Methods: This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. Results: Significantly higher left ventricular myocardial performance index (0.52 ± 0.06 vs. 0.41 ± 0.04, p < 0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p < 0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p < 0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p = 0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p = 0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p < 0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p =0.224). Conclusion: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Resumo Introdução: O desvio do septo nasal é a principal causa de obstrução das vias aéreas superiores. A obstrução crônica das vias aéreas superiores pode causar lesão miocárdica devido à hipóxia crônica. Os efeitos da septoplastia nas funções diastólica e sistólica do ventrículo esquerdo não são bem conhecidos. O índice de desempenho miocárdico é um parâmetro confiável e fácil de aplicar que reflete as funções cardíacas sistólica e diastólica. Objetivo: Investigar o efeito da septoplastia nasal no índice de desempenho miocárdico em pacientes com desvio de septo nasal. Método: Este estudo prospectivo consistiu em 50 pacientes consecutivos submetidos a septoplastia devido a desvio de septo nasal significativo sintomático em S ou C. A ecocardiogarfia transtorácica foi feita em todos os pacientes antes e 3 meses após a septoplastia. Os índices de desempenho miocárdico calculados foram comparados. Resultados: Um valor de indice de desempenho miocárdico ventricular esquerdo significantemente maior (0,52 ± 0,06 vs. 0,41 ± 0,04, p < 0,001), tempo mais longo de relaxamento isovolumétrico (95,0 ± 12,5 vs. 78,0 ± 8,6 ms, p < 0,001), tempo mais longo de contração isovolumétrica (45,5 ± 7,8 vs. 39,5 ± 8,6 ms, p < 0,001), tempo de desaceleração mais longo (184,3 ± 32,5 vs. 163,6 ± 45,4 ms, p = 0,004), maior razão de pico de velocidade transmitral precoce e tardia (E / A) (1,42 ± 0,4 vs. 1,16 ± 0,2, p = 0,006) e menor tempo de ejeção (270,1 ± 18,3 vs. 286,5 ± 25,8 ms, p < 0,001) foram observados antes da septoplastia quando comparados aos valores obtidos 3 meses após a septoplastia. A fração de ejeção sistólica do ventrículo esquerdo foi semelhante antes e após a septoplastia (63,8 ± 2,8% vs. 64,6 ± 3,2%, p = 0,224). Conclusão: A cirurgia de septoplastia não apenas reduz os sintomas em pacientes com desvio de septo nasal, mas também pode melhorar o desempenho ventricular esquerdo. Assim, o tratamento precoce do desvio de septo nasal é sugerido para prevenir possíveis eventos cardiovasculares futuros.

[Measurement of nasal septum area in 128 Chinese patients with nasal septum deviation].

Objective:Establish the anatomical parameters of the nasal septum and the area of each component in patients with nasal septum deviation, for the sake of guiding the scope of surgical resection for correction of nasal septum deviation. Methods:This is a retrospective study of 128 cases of sinus computer tomography images of patients with nasal septum deviation, marked 9 nasal septal anatomical locations, measured the area of the nasal septum and its components, and analyzed the trend of the percentage of the area of the nasal septum cartilage in the total area of the nasal septum with age. Results:The total area of the nasal septum in the 128 patients with nasal septum deviation is: （2951.96±305.91） mm², the area of nasal septal cartilage: （961.89±229.64） mm², the area of the vertical ethmoid plate: （1123.96±214.17） mm², the area of the vomerine: （652.77±108.09） mm². The area of male septum is larger than that of female. As age increases, the nasal septal cartilage gradually decreases, and the percentage of the nasal septal cartilage area in the total area of the nasal septum gradually decreases. Conclusion:Elderly people who undergo nasal septum correction should be carefully considered to grasp the scope of resection, and the influence of gender on the area of nasal septum should also be paid attention.

Associations between the severity of nasal septal deviation and nasopharynx volume in different ages and sexes: a cone-beam computed tomography study.

BACKGROUND: Nasal septum deviation (NSD) can cause serious anatomical and clinical complications. It can change the breathing pattern and thus alter the anatomy of the airway structures. Despite its importance, the association between NSD with the nasopharynx volume (NPV) has not been assessed before. Therefore, we aimed to investigate it for the first time. METHODS: Archival CBCTs of 202 patients older than 17 years and without any history of trauma or pathology of the nasopharynx and without any orthodontic/orthognathic treatments were evaluated (129 women, 73 men, mean age: 36.24 ± 14.61 years). All included CBCTs must have been taken with a 12 × 8 field of view and fully covered the nasopharynx areas. The extent of NSD (°) and NPV (mm3) were measured. NSDs were categorized as mild (NSD ˂ 9°), moderate (9 ≤ NSD ≤ 15°), and severe (NSD ˃ 15°). Associations between sex, age, NSD, and nasopharynx volume were assessed using independent-samples t test, chi-square, one-way ANOVA, Tamhane post hoc test, Pearson and point-biserial correlation coefficients, and multiple linear regressions (α = 0.05). RESULTS: Mean NSDs were 11.27 ± 4.69° (range 1-19.5), 11.58 ± 4.63°, and 10.70 ± 4.76° in the sample, females, and males, respectively (P > 0.05). Of females, 27.9%, 40.3%, and 31.8% had mild, moderate, and severe NSDs. These were 35.6%, 39.7%, and 24.7% in males (P > 0.05). Mean NPVs were 4.88 ± 1.49, 4.80 ± 1.43, and 5.04 ± 1.60 mm3 in the sample, females, and males, respectively (P > 0.05). Mean NPVs were 6.41 ± 1.21, 4.87 ± 0.73, and 3.30 ± 0.65 mm3 in mild, moderate, and severe NSD groups (all P values = 0.000). Mean ages were 27.06 ± 6.49, 29.80 ± 9.64, and 54.73 ± 8.45 years in mild, moderate, and severe NSD groups (severe group being older than the other two groups, P = 0.000). NSD was strongly, negatively correlated with NPV (R = - 0.793, P = 0.000). Sex was not correlated with NPV or NSD (P ≥ 0.189). Age was negatively and positively correlated with NPV and NSD, respectively (P = 0.000). Modeling NSD (ß = -0.776, P = 0.000) as a predictor for NPV rendered age effect insignificant (P > 0.05). CONCLUSIONS: It was found, for the first time, that the more deviated the nasal septum, the smaller the nasopharynx volume. Aging might increase NSD and through it, reduce the nasopharynx volume. Sex might not affect NSD or NPV.

Nasal septum deviation and Eustachian tube function: A prospective case-control study based on tympanometry, tubomanometry, and ETDQ-7.

INTRODUCTION: The influence of isolated nasal septum deviation (NSD) in the Eustachian Tube (ET) function is still undetermined. OBJECTIVE: compare ET function between patients with severe NSD and patients with adequate nasal patency in terms of symptomology and objective exams and assess the impact of septoplasty in ET function in patients with severe NSD. METHODS AND METHODOLOGY: a prospective study was conducted. In the first phase of the study, two opportunistic samples were selected: 35 patients with severe NSD for group A and 35 patients with adequate nasal patency for group B. Both groups were evaluated through Nasal obstruction Subjective Questionnaire (NOSE) and ET dysfunction questionnaire 7 (ETDQ7) -, and through two objective exams to assess ET function - tympanometry, and tubomanometry (TMM); results were compared between group A and B. In the second phase of the study, the patients from group A underwent septoplasty and were re-evaluated through ETDQ7, tympanometry and TMM; results were compared before and after surgery. RESULTS: we found a statistically significant difference between patients with NSD and patients with adequate nasal patency in NOSE and ETDQ7 (higher scores in the latter), and TMM (worse results in patients with NSD); the difference in tympanometry was not statistically significant. The side of the NSD did not correlate with the side of the dysfunction. After septoplasty, patients from group A had statistically significant lower scores in ETDQ7 and a lower proportion of patients with findings compatible with ET dysfunction using TMM. CONCLUSION: according to our results, severe NSD alone is a cause of ET dysfunction; septal surgery might improve ET function in these patients.

Conclusion: according to our results, severe NSD alone is a cause of ET dysfunction; septal surgery might improve ET function in these patients. (AU)

Introducción: Aún sigue sin determinarse la influencia aislada de la desviación del septo nasal (DSN) en la función de la trompa de Eustaquio (TE). Objetivo: Comparar la función de la TE entre los pacientes con DSN grave y los pacientes con patencia nasal adecuada, en términos de sintomatología y exámenes objetivos, y evaluar el impacto de la septoplastia en la función de la TE en pacientes con DSN grave. Métodos y metodología: Se realizó un estudio prospectivo seleccionándose 2 muestras oportunistas en la primera fase del mismo: 35 pacientes con DSN grave en el grupo A, y 35 pacientes con patencia nasal adecuada en el grupo B. Se evaluó a ambos grupos utilizando los cuestionarios Nasal Obstruction Subjective Questionnaire (NOSE) y disfunción de TE (ETDQ7), así como mediante 2 exámenes objetivos, para evaluar la función de la TE: timpanometría y tubomanometría (TMM), comparándose los resultados entre los grupos A y B. En la segunda fase del estudio, los pacientes del grupo A fueron sometidos a septoplastia y reevaluados mediante ETDQ7, timpanometría y TMM, comparándose los resultados de antes y después de la cirugía. Resultados: Encontramos una diferencia estadísticamente significativa en NOSE y ETDQ7 entre los pacientes con DSN y los pacientes con patencia nasal adecuada (con puntuaciones superiores en este último), y TMM (con peores resultados en los pacientes con DSN), no siendo estadísticamente significativa la diferencia en la timpanometría. El lado de DNS no se correlacionó con el lado de la disfunción. Tras la septoplastia, los pacientes del grupo A reflejaron puntuaciones menores en ETDQ7 con significación estadística, y existió una menor proporción de pacientes con hallazgos compatibles con la disfunción de la TE utilizando TMM. Conclusión: Con arreglo a nuestros resultados, la DNS en solitario es una causa de disfunción de la TE, pudiendo mejorar la septoplastia la función de la TE en estos pacientes. (AU)

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation.

INTRODUCTION: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not well known. The myocardial performance index is an easy-to-apply and reliable parameter that reflects systolic and diastolic cardiac functions. OBJECTIVE: The present study aimed to investigate the effect of nasal septoplasty on the myocardial performance index in patients with nasal septal deviation. METHODS: This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. RESULTS: Significantly higher left ventricular myocardial performance index (0.52 ±â€¯0.06 vs. 0.41 ±â€¯0.04, p <  0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p <  0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p <  0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p =  0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p =  0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p <  0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p  = 0.224). CONCLUSION: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

The effect of nasal septum deviation on voice aging.

PURPOSE: The aging process of the voice differs among individuals, and the factors that affect age-related changes in voice are not well-defined. In this study, we investigated the difference between older people with nasal septum deviation (NSD) and older people without NSD in terms of degree of aging voice using objective and subjective voice assessment tools. METHODS: The study included 94 patients (47 women, 47 men) aged >65 years. Nasal septum deviation was determined in 45 patients (NSD group), and 49 patients had no nasal pathology (control group). Maximum phonation time (MPT), GRBAS scale, and acoustic voice analysis parameters were compared between the NSD and control groups; sub-group analysis disaggregated by sex was also performed. RESULTS: No significant difference was observed between the NSD and control groups with respect to MPT, GRBAS scale, and acoustic voice analysis parameters in the total study population and among male subjects. The only parameter that showed a significant difference between sub-groups of female subjects was soft phonation index (SPI) (p=.03). CONCLUSIONS: To the best of our knowledge, this is the first study to analyze the effect of NSD on the voice aging. With the findings of the present study, NSD does not seem to have an effect on voice aging, and also it can be suggested that septoplasty will not have an effect on preventing presbyphonia. Further studies on larger groups of patients are required to provide more definitive evidence on this subject.
