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.

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.

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 (β = −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.

Septoplasty alone is not suitable for most structural nasal obstructions

Septoplasty is widely used in the treatment of structural nasal obstructions, and it also has a good effect and a high degree of postoperative satisfaction. However, there a large number of structures demonstrate abnormalities related to structural nasal obstruction, including the external nose, maxilla, nasal cavity and paranasal sinus. Nasal septum deviation is only one signs of structural nasal obstruction and does not represent all possible structural abnormalities of the nasal cavity and its surrounding structure. Septoplasty is only performed to correct deviations of the nasal septum, which in many cases is obviously insufficient in restoring the symmetry of the nasal structure. Therefore, septoplasty alone is not suitable for the treatment of most structural nasal obstructions. Nasal ventilation expansion surgery, which typically covers more abnormal structural correction procedures than septoplasty, should be used when describing the treatment of structural nasal obstruction.

Asymmetry of inferior turbinate in patients with nasal septum deviation and its significance for nasal ventilation surgery

PURPOSE

To investigate the asymmetry of the inferior turbinate (IT) in patients with nasal septum deviation (NSD).

METHODS

The paranasal sinus computed tomography (CT) of 100 patients with NSD were retrospectively investigated from February 2018 to December 2019. The thickness of IT, IT mucosa and IT bone, the distance between the IT and the midline were measured on both the concave and convex sides, and which correlation with NSD was analyzed.

RESULTS

The widths of the IT, IT bone and IT medial mucosa on the concave side were larger than those on the convex side (all P < 0.05). The distance from the IT and IT bone to the midline on the concave side was smaller than those on the convex side (P < 0.05, respectively). The degree of NSD had a negative correlation with the widths of the IT and IT bone on the convex side, and the distance between the IT and the midline on the concave side; and a positive correlation with the distance from IT and IT bone to the midline on the convex side, and IT mucosa thickness on the concave side (all P < 0.05).

CONCLUSION

The asymmetric IT width is mainly caused by both hypertrophies of the IT mucosa on the concave side and atrophy of the IT bone on the convex side. Therefore, during the surgery of nasal ventilation reconstruction, the IT on the convex side are suggested to be protected from intervention. In contrast, it is necessary to lateralize the IT bone and reduce the IT submucosal tissue on the concave side. However, routine excision of the IT bone is not recommended.

Risk of dental malocclusion in children with upper respiratory tract disorders: A case-control study of a nationwide, population-based health claim database

OBJECTIVES

The aim of this study was to evaluate the association between different upper respiratory tract disorders and severe dental malocclusion in pediatric patients.

METHODS

Newly diagnosed patients (N = 773) with dental malocclusion aged 8-18 years and controls (N = 3865) were identified from the health claim records of the Longitudinal Health Insurance Database 2000 of Taiwan's National Health Insurance Research Database. Controls were frequency matched to the cases by sex, age group, and index year. Univariate and multiple logistic regression analyses were used to evaluate the association between severe dental malocclusion and six common upper respiratory tract disorders, including acute sinusitis, allergic rhinitis, chronic sinusitis, nasal septum deviation, nasal polyps, and hypertrophy of tonsil and adenoids.

RESULTS

The risk of severe dental malocclusion was significantly elevated in pediatric patients with three upper respiratory tract disorders, including acute sinusitis (adjusted odds ratio [aOR] = 1.66, 95% confidence interval [95% CI] 1.39-1.99), allergic rhinitis (aOR = 1.64, 95% CI 1.34-2.02), and chronic sinusitis (aOR = 2.01, 95% CI 1.27-3.19). When all the six upper respiratory tract disorders were simultaneously included in the multiple logistic regression analysis, acute sinusitis (aOR = 1.48, p < 0.001) and allergic rhinitis (aOR = 1.34, p < 0.010) were significantly and independently associated with an increased risk of severe dental malocclusion.

CONCLUSIONS

Findings from this nationwide, population-based case-control study indicated that acute sinusitis and allergic rhinitis were independently and significantly associated with an increased risk of severe dental malocclusion in pediatric patients. Pediatricians should remain vigilant for the risk of dental malocclusion in their patients with these disorders.

Readability and quality assessment of internet-based patient education materials related to nasal septoplasty

BACKGROUND

Given that nasal septoplasty is a common procedure in otolaryngology - head and neck surgery, the objective of this study was to evaluate the quality and readability of online patient education materials on septoplasty.

METHODS

A Google search was performed using eight different search terms related to septoplasty. Six different tools were used to assess the readability of included patient education materials. These included the Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning-Fog Index, Simple Measure of Gobbledygook Index, Coleman-Liau Index, and Automated Readability Index. The DISCERN tool was used to assess quality and reliability.

RESULTS

Eighty-five online patient education materials were included. The average Flesch-Reading Ease score for all patient education materials was 54.9 ± 11.5, indicating they were fairly difficult to read. The average reading grade level was 10.5 ± 2.0, which is higher than the recommended reading level for patient education materials. The mean DISCERN score was 42.9 ± 10.5 and 42% (36/85) of articles had DISCERN scores less than 39, corresponding to poor or very poor quality.

CONCLUSION

The majority of online patient education materials on septoplasty are written above the recommended reading levels and have significant deficiencies in terms of their quality and reliability. Clinicians and patients should be aware of the shortcomings of these resources and consider the impact they may have on patients' decision making.

Factors influencing the sinus membrane thickness in edentulous regions: a cone-beam computed tomography study

Background

During implant treatment in the maxillary molar area, maxillary sinus floor augmentation is often performed to ameliorate the reduced alveolar bone height attributable to bone remodeling and pneumatization-induced expansion of the maxillary sinus. However, this augmentation may cause complications such as misplaced implants, artery damage, and maxillary sinus mucosal perforation; infections like maxillary sinusitis; and postsurgical complications such as bone graft leakage and postoperative nasal hemorrhaging. To reduce the complications during maxillary sinus floor augmentation and postoperative infections, we performed retrospective investigations of various systemic and local factors that influence pre-operative sinus mucosal thickness (SMT) by using cone-beam computed tomography (CBCT). Subjects included patients who underwent maxillary sinus floor augmentation in an edentulous maxillary molar area with a lateral approach. Pre-operative SMT, existing bone mass, and nasal septum deviation were measured using CBCT images. Relationships between SMT and the following influencing factors were investigated: (1) age, (2) sex, (3) systemic disease, (4) smoking, (5) period after tooth extraction, (6) reason for tooth extraction, (7) residual alveolar bone height (RBH), (8) sinus septa, and (9) nasal septum deviation. Correlations were also investigated for age and RBH (p < 0.05).

Results

We assessed 35 patients (40 sinuses; 11 male, 24 female). The average patient age was 58.90 ± 9.0 years (males, 57.9 ± 7.7 years; females, 59.9 ± 9.4 years; age range, 41–79 years). The average SMT was 1.09 ± 1.30 mm, incidence of SMT > 2 mm was 25.0%, incidence of SMT < 0.8 mm was 50.0%, and the average RBH was 2.14 ± 1.02 mm. The factors that influenced SMT included sex (p = 0.0078), period after tooth extraction (p = 0.0075), reason for tooth extraction (p = 0.020), sinus septa (p = 0.0076), and nasal septum deviation (p = 0.038).

Conclusions

Factors associated with higher SMT included male sex, interval following tooth extraction < 6 months, periapical lesions, sinus septa, and nasal septum deviation. Factors associated with SMT > 2 mm were sex and reason for tooth extraction, while factors associated with SMT < 0.8 mm were time following tooth extraction and nasal septum deviation. Despite the limitations of this study, these preoperative evaluations may be of utmost importance for safely conducting maxillary sinus floor augmentation.

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.

Neural crest-specific deletion of Bmp7 leads to midfacial hypoplasia, nasal airway obstruction, and disordered breathing modelling Obstructive Sleep Apnea

Pediatric obstructive sleep apnea (OSA), a relatively common sleep-related breathing disorder (SRBD) affecting approximately 1-5% of children, is often caused by anatomical obstruction and/or collapse of the nasal and/or pharyngeal airways. The resulting sleep disruption and intermittent hypoxia lead to various systemic morbidities. Predicting the development of OSA from craniofacial features alone is currently not possible and a controversy remains if upper airway obstruction facilitates reduced midfacial growth or vice-versa. Currently, there is no rodent model that recapitulates both the development of craniofacial abnormalities and upper airway obstruction to address these questions. Here, we describe that mice with a neural crest-specific deletion of Bmp7 (Bmp7ncko) present with shorter, more acute angled cranial base, midfacial hypoplasia, nasal septum deviation, turbinate swelling and branching defects, and nasal airway obstruction. Interestingly, several of these craniofacial features develop after birth during periods of rapid midfacial growth and precede the development of an upper airway obstruction. We identified that in this rodent model, no single feature appeared to predict upper airway obstruction, but the sum of those features resulted in a reduced breathing frequency, apneas and overall reduced oxygen consumption. Metabolomics analysis of serum from peripheral blood identified increased levels of hydroxyproline, a metabolite upregulated under hypoxic conditions. As this model recapitulates many features observed in OSA, it offers unique opportunities for studying how upper airway obstruction affects breathing physiology and leads to systemic morbidities.

The systolic pulmonary artery pressure and the E/e' ratio decrease after septoplasty in patients with grade 2 and 3 pure nasal septal deviation

INTRODUCTION

Nasal septal deviation may contribute to a wide range of symptoms including nasal obstruction, headache, increased secretion, crusting, mucosal damage, and loss of taste and smell. Excessive increase in the respiratory resistance, as seen in nasal septal deviation, results in reduced lung ventilation, thereby potentially leading to hypoxia, hypercapnia, pulmonary vasoconstriction. The deformities in the nasal cavity can be associated with major respiratory and circulatory system diseases.

OBJECTIVE

To investigate cardiovascular effects of septoplasty by comparing pre- and postoperative transthoracic echocardiography findings in nasal septal deviation patients undergoing septoplasty.

METHODS

The prospective study included 35 patients with moderate and severe nasal septal deviation (mean age, 23.91±7.01) who underwent septoplasty. The Turkish version of the nasal obstruction symptom evaluation, NOSE questionnaire, was administered to each participant both pre- and postoperatively in order to assess their views on the severity of nasal septal deviation, the effect of nasal obstruction, and the effectiveness of surgical outcomes. A comprehensive transthoracic echocardiography examination was performed both preoperatively and at three months postoperatively for each patient and the findings were compared among patients.

RESULTS

Mean preoperative NOSE score was 17.34±1.62 and the mean postoperative score was 2.62±1.68 (p=0.00). Mean preoperative systolic pulmonary artery pressure value was 22.34±4.31mmHg and postoperative value was 18.90±3.77mmHg (p=0.00). Mean E/e' ratio was 5.33±1.00 preoperatively and was 5.01±0.90 postoperatively (p=0.01). The NOSE scores, systolic pulmonary artery pressure values, and the E/e' ratios decreased significantly after septoplasty (p<0.05 for all), whereas no significant difference was found in other transthoracic echocardiography parameters (p>0.05).

CONCLUSION

The decrease in NOSE scores following septoplasty indicated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to nasal septal deviation may be a cardiovascular risk factor and may affect transthoracic echocardiography measurements. Moreover, the significant decrease in the systolic pulmonary artery pressure value and E/e's ratio following septoplasty indicated that negative echocardiographic findings may be prevented by this surgery.

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 ± 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.

Does septoplasty affect 24-h ambulatory blood pressure measurements in patients with type 2 and 3 pure nasal septal deviation?

PURPOSE

To investigate day, night and 24 h all blood pressure effects of septoplasty by comparing pre- and post-operative 24-h ambulatory blood pressure monitoring (ABPM) values of NSD patients undergoing septoplasty.

MATERIALS AND METHODS

The prospective study included 20 patients with type 2 and 3 pure NSD (mean age, 23.60 ± 6.51) who underwent septoplasty in our clinic. Nasal obstruction symptom evaluation (NOSE) questionnaire was applied to each participant both pre- and post-operatively to evaluate their views on the severity of NSD and the effectiveness of surgical outcomes. A comprehensive ABPM examination was performed both 2 days before surgery and at three months postoperatively for each patient and the findings were compared among patients.

RESULTS

Preoperative NOSE score was 87.75 ± 7.34% and the postoperative score was 12.50 ± 6.58% (p = 0.000). Following septoplasty, 24-h systolic blood pressure (24SBP) declined from 119.4 ± 9.9 mmHg to 112.2 ± 8.0 mmHg (p = 0.000), daytime SBP (DSBP) declined from 125.9 ± 11.0 mmHg to 117.9 ± 8.4 mmHg (p = 0.000), nighttime SBP (NSBP) declined from 112.7 ± 9.5 mmHg to 105.5 ± 7.9 mmHg (p = 0.000), 24-h pulse pressure (24PP) declined from 46.7 ± 10.1 mmHg to 44.0 ± 8.4 mmHg (p = 0.015), and mean daytime PP (DPP) declined from 46.9 ± 9.7 mmHg to 44.6 ± 8.6 mmHg (p = 0.026).

CONCLUSION

The decline in NOSE percentages following septoplasty demonstrated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to NSD may affect ABPM measurements. Moreover, the significant decrease in the 24SBP, DSBP, NSBP, 24PP and DPP following septoplasty showed that NSD may cause cardiovascular risk and this risk may be prevented by septoplasty.

Application of continuous suture of inferior turbinate in surgery for chronic hypertrophic rhinitis with or without nasal septum deviation

PURPOSE

To explore the application value of continuous suture of the inferior turbinate in inferior turbinate submucosal bone resection.

METHODS

Twenty patients with chronic hypertrophic rhinitis with or without nasal septum deviation underwent inferior turbinate submucosal bone resection with or without septoplasty. The inferior turbinate was continuously sutured with or without nasal septum suture after surgery. The nasal cavity was not packed. The postoperative clinical outcome was evaluated using visual analog scales (VASs), saccharin test, nasal endoscopy, and nasal resistance test. Postoperative complications were recorded.

RESULTS

All 20 endoscopic surgeries were successfully performed. One day after surgery, the VAS scores of nasal pain (1.3 ± 0.5), headache (0.8 ± 0.4), tearing (0.3 ± 0.3), and bleeding (0.3 ± 0.3) in patients were low; 1 week after surgery, the nasal mucociliary transport time was not significantly prolonged compared to that before surgery (P > 0.05); 1 month after surgery, the symptoms of nasal congestion had improved significantly, as the VAS score for nasal congestion was lower than that before surgery (P < 0.05); the volume of the hypertrophied inferior turbinate of all patients was reduced, the mucous membrane was smooth and rosy, the nasal septum was centrally located, and the total nasal resistance values at 150 Pa pressure had returned to the normal reference range (0.282 ± 0.103 Pa/cm³/s); no complications such as bleeding, nasal infection, nasal dryness, and olfactory disorders occurred.

CONCLUSION

After inferior turbinate submucosal bone resection with or without septoplasty, inferior turbinate continuous suture with or without nasal septum suture instead of nasal packing can significantly improve postoperative discomfort, improve nasal ventilation, protect nasal function, and accelerate postoperative recovery.

The correlation of computed tomography in the evaluation of septoplasty patients

Background

Septoplasty is one of the frequently applied nasal surgical procedures. There is still no gold standart objective method to evaluate the patients whom suffers from nasal blockage. To evaluate the septoplasty candidate with a Paranasal Computerised Tomography (PNCT) is one of the most discussed topic in the otorhinolaryngology surgical philosophy.

Objectives

In this study, we aim to interpret the value of nasal valve areas measured by PNCT for both septoplasty candidates and the control population. We believe that this information could be useful for the evaluation of patients before undergoing a septoplasty procedure.

Material and Methods

600 coronal and axial tomography sections performed between May 2014 and February 2018 at the University Of Gaziantep Radiology Dept. were assessed. These tomography sections were divided into two groups called the septoplasty and the control. The septoplasty group was made up of three hundred paranasal sinus tomography images scanned before patients' septoplasty operations. The control group was created by screening 300 maxillofacial tomography's which were taken due to the suspicion of trauma at the University Of Gaziantep Emergency Clinic between May 2014 and January 2018.

Results

There were 192 (64%) patients with left nasal septal deviation and 108 (36%) patients with right nasal septal deviation. The Independent Sample T-Test revealed that the mean internal nasal valve angle in the left septoplasty group was significantly lower than that of the control group (P < 0.005). A comparison of the right side nasal values revealed a significant statistical change according to the Independent Sample T-Test between the value of the right septoplasty and the control groups (P < 0.005).

Conclusion

The sectional areas of nasal tomography images may show different values. However, it is still difficult to say that the clinical application of tomography images could be used as one of the indication criteria for the septoplasty procedure.

The Possible Associations of Nasal Septal Deviation with Mastoid Pneumatization and Chronic Otitis

BACKGROUND:

The nasal septum deviation is the most common deformity of the nasal, and that can be congenital or acquired. Despite many studies exist about the impact of nasal septum deviation on chronic sinusitis and also association between chronic otitis and mastoid pneumatization; few studies exist about the impact of nasal septum deviation on chronic otitis and mastoid pneumatization.

AIM:

The aim of this study was to evaluate the associations of nasal septum deviation and mastoid pneumatization and chronic otitis.

METHODS:

In this study review, all CT scans of PNS and Mastoid View in the imaging section from Imam Ali hospital in 2016-2017 years and cases of nasal septum deviation were enrolled. The nasal septum deviation was recorded, and the degree of nasal septum deviation in the coronal plane that showed the maximum deviation of the nasal septum was recorded. The volume of the mastoid cells automatically and directly was calculated using three diameter measurements (2 coronal diameters and 1 axial diameter) by the program. The software of SPSS 22 was used for statistical analysis.

RESULTS:

There was no relationship between nasal septum deviation severity and incidence of mastoid pneumatization in patients with nasal septum deviation (P > 0.05). There was relationship between nasal septum deviation severity and chronic otitis in patients with nasal septum deviation (P < 0.05). In patients with moderate and severe intensity of nasal septum deviation, the volume of mastoid air cells in deviation side was lower than the front side (P < 0.05).

CONCLUSION:

Based on the results of the CT scan, in patients with moderate and severe nasal septum deviation intensity, the volume of mastoid air cells in deviation side was lower than the front side. Also, there was a relationship between nasal septum deviation severity and chronic otitis.

Histopathological effects of septoplasty techniques on nasal septum mucosa: an experimental study

OBJECTIVE

The aim of this study is to evaluate the histopathological effects of septoplasty techniques on the nasal septal mucosa of rabbits with light and electron microscope.

METHODS

The study was performed on 21 rabbits between August 2016 and February 2017. Rabbits were randomly divided into three groups. In Group-1, while preserving the L-strut structure of the septum, cartilage resection, was performed by open technique septoplasty. In Group-2, the same procedure was done except the resected cartilage was crushed and put back in place. No surgical procedure was performed on the Control group. Postoperative 2nd month; the specimens were histopathologically evaluated by light and electron microscope in terms of changes in the morphology of septum mucosa, perichondrial thickness, cilia and goblet cell deprivation, loss in glands, fibrosis and inflammatory cell infiltration in the lamina propria.

RESULTS

The deprivation in cilia, goblet cells, serous gland and increase in the amount of collagen fibers were examined in both Group-1 and 2. The difference in Group-1 and Group-2 were statistically significant in terms of presence of cilia, number of goblet cells and glands and increase in collagen fibers when compared to control (p < 0.001, p = 0.002, p = 0.020, p = 0.002, respectively). In terms of perichondrium thickness, statistically significant difference was found between the Control and Group-2 (p < 0.001). CONCLUSıON: In this study, histopathological findings supported that the presence of cartilage in the septum is necessary to prevent the mucosal changes. Long-term studies are needed to observe whether changes in the morphology of epithelium and gland proceed more than 2 months follow-up.

Rhinoseptoplasty in children

INTRODUCTION

Untreated septal and/or nasal pyramid deviation in children should be corrected as soon as possible, because they can result in esthetic or functional problems years later.

OBJECTIVE

To report the surgical experience in treating children with nasal septum and/or nasal pyramid deviation.

METHODS

Review of medical records of 202 children, 124 (61.4%) males and 78 (38.6%) females, between 4 and 16 years of age (M=11 years) who underwent rhinoplasty and/or septoplasty in a Pediatric Otolaryngology Service of the Dept. of Otolaryngology and Head and Neck Surgery between January 1994 and January 2010.

RESULTS

Septoplasty performed in 157 cases (77.7%); rhinoseptoplasty in 23 cases (11.4%), and rhinoplasty in 22 cases (10.9%).

CONCLUSION

Nasal changes should be corrected in children, in order to provide harmonious growth, and prevent severe sequelae found in mouth breathers.

The effect of septoplasty on pulmonary artery pressure and right ventricular function in nasal septum deviation

Nasal septum deviation (NSD) can cause obstruction of the upper airway, which may lead to increased pulmonary artery pressure (PAP) and right ventricle dysfunction. The aim of the present study was to evaluate the effect of septoplasty on right ventricular function and mean PAP of patients with marked NSD. 25 patients with marked NSD (mean age = 31.8 ± 12.3 years) and 27 healthy volunteers (mean age = 34.5 ± 10.8 years) were enrolled. Echocardiography was performed for all subjects and right ventricular function and mean PAP were evaluated before and 3 months after septoplasty. Tricuspid annular plane systolic excursion (TAPSE) and tricuspid annulus early diastolic myocardial velocity (E') were significantly lower in patients with NSD than control subjects, while right ventricle myocardial performance index (RVMPI) and mean PAP were significantly higher (respectively, p = 0.006, 0.037, 0.049, 0.046). When preoperative and postoperative findings were compared, the mean PAP decreased whereas TAPSE increased significantly (respectively, p = 0.007, 0.03). The results of the present study demonstrated that mean PAP increased and right ventricular function worsened in patients with NSD. However, mean PAP decreased and right ventricular function tended to recover after septoplasty.

Endoscopic septoplasty in primary cases using electromechanical instruments: surgical technique, efficacy and results

INTRODUCTION AND OBJECTIVES

The microdebrider is a surgical tool which has been used successfully in many endoscopic surgical procedures in otolaryngology. In this study, we analysed our experience using this powered instrument in the resection of obstructive nasal septum deviations.

SUBJECTS AND METHODS

This was a longitudinal, prospective, descriptive study conducted between January and June 2007 on 141 patients who consulted for chronic nasal obstruction caused by a septal deviation or deformity and underwent powered endoscopic septoplasty (PES).

RESULTS

The mean age was 39.9 years (15-63 years); 60.28% were male (n=85) The change in nasal symptom severity decreased after surgery from 6.12 (preoperative) to 2.01 (postoperative). Patients undergoing PES had a significant reduction of nasal symptoms in the pre- and postoperative period, which was statistically significant (P<.05). There were no statistically significant differences between the results at the 2 nd week, 6th week and 5th year after surgery. The 100% of patients were satisfied with the results of surgery and no patient answered "No" to the question added to compare patient satisfaction after surgery. Minor complications in the postoperative period were present in 4.96% of the cases.

CONCLUSIONS

Powered endoscopic septoplasty allows accurate, conservative repair of obstructive nasal septum deviations, with fewer complications and better functional results. In our experience, this technique offered significant perioperative advantages with high postoperative patient satisfaction in terms of reducing the severity of nasal symptoms.
