Improvement of Pulmonary Functions Following Septoplasty: How Are Lower Airways Affected?

Improvement in Pulmonary Function Tests After Septoplasty: A Longitudinal Study

Introduction The relationship between the nasal and pulmonary systems is rooted in the shared anatomy and physiology of the upper and lower respiratory tracts. Our study objective was to assess the improvement in pulmonary function tests (PFTs) after septoplasty in patients with a deviated nasal septum (DNS). Methods A longitudinal study was conducted at a tertiary care center from October 1, 2022, to March 31, 2024. Patients aged 18-55 years with chronic nasal obstruction due to an isolated DNS were included in the study. Patients under 18 or over 55 years of age, those undergoing combined nasal surgeries, and those with comorbidities such as hypertension, diabetes, chronic smoking, chronic obstructive pulmonary disease, bronchial asthma, turbinate hypertrophy, chronic sinusitis, or nasal polyposis were excluded. Pre-operative assessments included detailed ear, nose, and throat examinations, routine blood investigations, X-rays of the chest and paranasal sinuses (Waters' view), PFTs (spirometry), the Sino-Nasal Outcome Test-22 (SNOT22) questionnaire, and the six-minute walk test (6MWT). Post-operative assessments included repeated spirometry, a 6MWT at three weeks post-surgery, and the SNOT22 questionnaire for subjective symptom assessment. Results Participants included 30 males and 30 females, with a mean age of 35.6 ± 8.2 years. Significant improvements (p < 0.05) were observed in PFT parameters (forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, peak expiratory flow), exercise capacity (6MWT distance), and symptom severity (SNOT22 scores) post-septoplasty. High levels of patient satisfaction and notable improvements in quality of life were reported. The average hospital stay was 2.5 days. Conclusion Septoplasty in patients with DNS significantly improves pulmonary function, exercise capacity, and symptom severity, with high patient satisfaction and minimal complications.

The Effects of Nasal Surgery on Pulmonary Function: A Systematic Review and Meta-Analysis

OBJECTIVE

A deviated nasal septum (DNS) can result in an anatomical obstruction and impact lung function through prolonged suboptimal inspiration. Given the improvements in respiration reported by patients following septoplasty or septorhinoplasty (with or without inferior turbinate reduction), our study investigated the effect of these procedures on pulmonary function through a systematic review and meta-analysis.

DATA SOURCES

Medline, Embase, Cochrane Databases, Web of Science, and Google Scholar.

REVIEW METHODS

The review was registered with PROSPERO [CRD42022316309]. The study population was composed of adult patients (18-65) who were symptomatic with confirmed DNS. Extracted outcomes (pre-operative versus postoperative) included the six-minute walk test (6MWT) and pulmonary function tests (FEV1, FVC, FEV1/FVC, FEF25-75, PEF). Meta-analyses were performed using a random-effects model.

RESULTS

Three studies included measures of the 6MWT in meters and all three found a statistically significant increase in the distance walked after surgery with a mean difference of 62.40 m (95% CI 24.79-100.00). Statistically significant improvements in PFT outcomes were observed with a standard mean difference of 0.72 for FEV1 (95% CI 0.31-1.13), 0.63 for FVC (95% CI 0.26-1.00), and 0.64 for PEF (95% CI 0.47-0.82). Of the twelve studies which measured PFT outcomes, six showed statistically significant improvements, three studies showed mixed results, and three studies found no difference in PFT outcomes between pre-and post-surgery testing.

CONCLUSIONS

The present study suggests that pulmonary function does improve after nasal surgery for DNS, but the high heterogeneity observed in the meta-analyses indicates that the evidence supporting this conclusion is low. Laryngoscope, 133:2837-2845, 2023.

Can Upper Airway Surgeries Improve Lower Airway Function ? A Prospective Study

Deviated nasal septum and turbinate hypertrophy are the most common causes for nasal obstruction, which compromise nasal airflow and increases airway resistance. These conditions can further reduce the airflow to lung, which will affect the lung volume and function subsequently reduces the exercise tolerance. The present study aimed to evaluate the impact of upper airway surgeries like septoplasty and turbinoplasty on lower airway functions using simple tests like spirometry and 6 min walking test (6mWt). This research was a prospective study. There were 88 subjects in the study who completed follow up. Spirometry and 6mWt was performed 1 day before and 1 month after surgery in all subjects. Mean preoperative and postoperative values of spirometry (forced vital capacity (FVC),forced expiratory volume in 1 s (FEV1), forced expiratory volume in 1 s/ forced vital capacity (FEV1/FVC), peak expiratory flow rate (PEFR) and 6mWt (systolic blood pressure, diastolic blood pressure, heart rate and oxygen saturation) parameters were compared and analyzed. Percentage of improvement of each parameter was compared with the type of surgery, side of obstruction, age of the patient and duration of symptom. Spirometry showed statistically significant improvement in all 4 parameters after surgery in 86 subjects. 6mWt showed statistically significant improvement in SBP and SpO2 and there was no significant improvement in DBP and HR. We also observed that improvement in parameters was irrespective of age and duration of symptoms. So this study concludes that airway narrowing nasal diseases can compromise lower airway function.

The Impact of Septoplasty on Cardiopulmonary Functions in Patients With Nasal Septal Deviation: A Prospective Comprehensive Analysis of Echocardiographic Outcome and Serum N-Terminal Pro BNP Levels

ABSTRACT

This study was designed to evaluate the impact of septoplasty on cardiopulmonary functions in patients with nasal septal deviation (NSD). A total of 30 consecutive adult patients (mean [standard deviation] age: 33.7 [10.9] years, 56.7% were males) who underwent septoplasty due NSD were included. Visual analog scale scores, nose obstruction symptom evaluation scale scores, serum N-terminal Pro BNP levels, and cardiologic examination findings on electrocardiogram, transthoracic echocardiography, and exercise treadmill testing were evaluated both 7 days before and 3-months after septoplasty operation. A significant decrease was noted in mean (standard deviation) visual analog scale scores (8.27 [0.83] versus 1.87 [0.73], P < 0.001), and nose obstruction symptom evaluation scores (83.7 [4.9] versus 12.7 [(5.4], P < 0.001) from preoperative to postoperative period, while maximum effort capacity was improved significantly (11.8 [1.9] versus 13.1 [2.1], P = 0.010) after septoplasty. Echocardiography findings at 3rd postoperative month revealed significant decrease in pulmonary artery systolic pressure (22.2 [3.2] versus 19.0 [3.6], P = 0.001), whereas significant increase in trans-mitral early diastolic rapid filling (E wave, 0.82 [0.14] versus 0.87 [0.13], P = 0.011), peak systolic velocity (S, 0.11 [0.02] versus 0.12 [0.02], P = 0.002), tricuspid annular plane systolic excursion (22.6 [3.2] versus 24.9 [2.9], P = 0.002), and right ventricle stroke volume (0.14 [(0.02] versus 0.15 [0.02], P = 0.013). In conclusion, our findings indicate favorable outcome of septoplasty in NSD patients not only in terms of improved nasal airflow but also cardiopulmonary functions, particularly the exercise capacity, pulmonary artery pressure, and right ventricular systolic functions. In this regard, our findings emphasize the important role of treating NSD patients without delay, given the likelihood of septoplasty to reverse the changes in the pulmonary artery system and to prevent onset of permanent cardiopulmonary dysfunction via amelioration of chronic obstruction of the upper respiratory tract.

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.

The Relationship of Preseptoplasty and Postseptoplasty Early Period Comfort Level With Nasal Obstruction, Sleep Quality, and Fatigue Severity: A Prospective Study

PURPOSE

The aim of this study was to compare the comfort level, nasal obstruction, sleep quality, and fatigue of patients with septal deviation preseptoplasty and postseptoplasty.

DESIGN

A prospective study conducted on 65 patients diagnosed with septal deviation.

METHODS

The data of the study were collected using an Introductory Information Form, a Short General Comfort Questionnaire, the Pittsburgh Sleep Quality Index, the Fatigue Severity Scale, and the Nasal Obstruction Septoplasty Effectiveness Scale. Linear regression was performed to evaluate the extent of the relationship of predictors affecting the comfort level.

FINDINGS

There was a statistically significant difference between the scores in the preoperative period and postoperative weeks 4 and 12. It was found that patients' use of sleeping medication, nasal obstruction, fatigue, and subjective sleep quality were the primary predictors of comfort levels in the preoperative period. In the postoperative week 4, comfort level predictors were daytime dysfunction and subjective sleep quality. Daytime dysfunction and working conditions were the predictors of comfort level in the postoperative week 12.

CONCLUSIONS

Many physical problems, such as nasal obstruction, fatigue, and sleep disorders were detected in patients before septoplasty. This study revealed the importance of performing septoplasty before sleep quality reaches a pathologic level or requires a sleep medication.

Effect of Septoplasty on Cardiopulmonary Functions in the Patients With Nasal Obstruction

OBJECTIVE

In this study, the authors aimed to investigate whether septoplasty has an effect on cardiopulmonary functions in the patients with nasal obstruction.

METHODS

A total of 53 patients with nasal obstruction due to septum deviation were included in the study. All the patients were performed septoplasty operation. Echocardiography and spirometric analysis were performed to assess cardiopulmonary functions before and after the operation (6 months postoperatively). The same evaluation was done for the degree of nasal obstruction by visual analogue scale. The preoperative and postoperative values were compared with each other.

RESULTS

Of the total 53 patients, 44 were males (83%) and 9 were female (17%). The mean age was 31.71 ± 9.46. The preoperative and postoperative mean right ventricular volumes were 2.0736 and 2.0906, respectively. The preoperative and postoperative mean left ventricular volumes were 4.4264 and 4.3528, respectively. The preoperative and postoperative mean cardiac septal thicknesses were 0.9642 and 0.9358, respectively. The mean value of preoperative cardiac posterior wall thicknesses was 0.8849, whereas the postoperative value was measured as 0.8340. The preoperative and postoperative mean pulmonary artery pressures were 27.8302 mmHg and 23.6415, respectively, and this was statistically significant (P < 0.001). The preoperative and postoperative mean forced vital capacities (FVC) were 4.3221 and 4.5564, respectively, and this was statistically significant (P < 0.001). The preoperative and postoperative mean 1st second forced expiratory volumes (FEV1) were 3.6698 and 3.8085, respectively, and this was statistically significant (P < 0.001). The mean value of preoperative FEV1/FVC was 84.9811, whereas postoperative mean value was measured as 83.8019 and this was statistically significant (P < 0.001).

CONCLUSION

In this study, the authors observed that septoplasty has positive effect on cardiopulmonary functions in the patients with nasal obstruction due to nasal septum deviation. The authors also claim that septoplasty may be a preventive procedure for future pathologies of cardiopulmonary functions.
