Association between nasal septal deviation and tinnitus: Insights from a 9-year nationwide cohort study.

Tinnitus is a condition where sound is perceived in the ear or head when no external sound stimulation is present. To date, no study has explored the correlation between nasal septal deviation (SD) and tinnitus using large-scale real-world data. This study hypothesized a potential relationship between tinnitus and SD, which we investigated using a 9-year large-scale cohort study. Nationwide cohort observational study. The SD group was selected from 1 million individuals randomly extracted from the National Health Insurance Service database. The non-SD group was obtained through propensity score matching considering several variables. The primary endpoint was tinnitus diagnosis. The study (SD) group included 10,790 individuals, and the non-SD group (control group) included 21,580 individuals. The overall hazard ratio (HR) for tinnitus in the SD group was 1.74 (95% CI: 1.62-1.89). In the subgroup analysis, the HR was 0.73 (95% CI: 0.68-0.79) for tinnitus in the male group, 1.12 (95% CI: 1.04-1.21) in the group with high economic status, 0.81 (95% CI: 0.75-0.89) in the group living in metropolitan areas, and 0.45 (95% CI: 0.42-0.49) in the younger age group (<50 years). In the SD group, the HR for tinnitus after septoplasty significantly decreased to 0.75 (95% CI: 0.63-0.90). From long-term follow-up, the prevalence of tinnitus was 1.74 times higher in the SD group compared with the control group. This phenomenon significantly decreased after septoplasty.

Septal Extension Spreader Graft Combined With Warped Alar Batten Graft for Improvement of Nasal Tip and Alar Asymmetry in Adult Cleft Lip Nasal Deformity.

This paper presents the findings of an observational study involving 38 patients to evaluate the application of a surgical technique utilizing an autologous costal cartilage scaffold for correcting nasal tip and alar asymmetry in unilateral cleft lip-nasal deformity. Nasal septum extension spreader grafts (SEG) and warped alar batten grafts, both made from autologous costal cartilage, were utilized in open rhinoplasty procedures. The warped alar batten graft was fixed to the caudal end of the SEG, with the lower lateral cartilage on the cleft side suspended to the free part of the newly created warped alar batten graft to lift the collapsed nasal alar further. Measurements of nasal tip height, nostril height, and the intersection angle of the nasal sill and alar (α) were taken before and after surgery, comparing the ratios between the normal and cleft sides. Patients were followed up for 2.5 to 5.5 years, with all cases showing successful healing and no complications. Postoperative improvements in nasal tip and nostril asymmetries were significant, with statistically significant changes observed in nasal tip height, nostril height, and the intersection angle of nasal sill and alar (α) ( P <0.05). The combined use of SEG and warped alar batten graft, both crafted from autologous costal cartilage, effectively corrected nasal tip and alar asymmetry in adult cleft lip nasal deformity cases.

Sinonasal Anatomic Variations in the Adult Population: CT Examination of 1200 Patients.

BACKGROUND: The nasal cavity and paranasal sinuses are one of the most frequently anatomically varied regions. Their size and shape vary from person to person, and ethnic origin may have a role in this variety. Recognizing this variations is so important for ear nose throat (ENT) specialists because they predispose to sinonasal pathologies and affect the complication rate and success of endoscopic sinus surgery. AIM: This study aimed to determine the frequency of sinonasal anatomic variations on paranasal sinus computed tomography (CT) in the Turkish population. METHODS: Patients who had undergone paranasal sinus CT with any complaints between 2013 and 2020 and aged over 18 years were included in the study. A total of 1209 patients who had undergone paranasal sinus CT were examined for coronal, axial, and sagittal plans retrospectively by two ENT professionals, and anatomical variations were evaluated. To assign the frequency of anatomic variations in a healthy population, patients who had previously undergone paranasal sinus and nasal surgery, who had nasal polyposis, and for whom CT evaluation was not possible due to intense sinusitis were excluded from the study. RESULTS: Among 1209 patients, 644 were male and 565 were female. The mean age of the patients was 33.7 years. The most common sinonasal anatomical variations were nasal septal deviation and agger nasi cells, while the least common variation is the supreme turbinate. No variation was found in 48 (3.9%) CTs. CONCLUSION: Almost all patients had at least one sinonasal anatomical variation. These variations should be known by the professionals who have interest in sinonasal disease and surgery.

[Drafâ ¢ approach to unilateral frontal sinus for contralateral drainage].

Objective:Anatomical variation or scar atresia of the drainage channel of the frontal sinus on the affected side, and opening the frontal sinus through the drainage channel of the frontal sinus on the affected side may lead to surgical failure. The purpose of this study is to explore a modified Draf Ⅲ operation to complete the drainage of the affected frontal sinus by removing the floor wall and septum of the frontal sinus and connecting the bilateral frontal sinus through the healthy side of the frontal sinus. Methods:Through the anatomical study of 2 skull bone specimens and 2 fresh frozen specimens, the surgical landmark and surgical approach were explored. Four patients with frontal sinus atresia and frontal sinusitis after DrafⅡb surgery in Eye & ENT Hospital of Fudan University were retrospectively analyzed. Descriptive method was used to analyze the data. Results:The bottom wall of bilateral frontal sinus was removed, and the bilateral frontal sinus was enlarged above the nasal septum to form a large common cavity. The uncinate process and ethmoid bubble were retained, and the midline drainage of the affected frontal sinus in the healthy side of the nasal cavity was completed. From August 2022 to April 2023, 4 patients with frontal sinus atresia and frontal sinusitis after DrafⅡb surgery for unilateral frontal sinus papilloma in Eye & ENT Hospital of Fudan University were treated with surgery. The headache symptoms disappeared after surgery, and the drainage of frontal sinus was spacious, the mucosa healed well and the drainage was unobstructed under endoscopy. There were no other postoperative complications. Conclusion:DrafⅢ approach to unilateral frontal sinus for contralateral drainage can drain the affected frontal sinus adequately. The essence of this operation is to drain the bilateral frontal sinus in the unilateral nasal cavity, and this operation has short path, less trauma, and a broader prospect, which is suitable for promotion.

Intraoperative Measurement-Based Approach to Supratip Deformity in Open Structural Rhinoplasty.

BACKGROUND: Supratip deformity is one of the most common complications after open rhinoplasty. This study aimed to define a new risk scoring system for supratip deformity and determine the distances that should be left between the tip defining point (TDP) and anterior septal angle (ASA) to prevent it. METHODS: Four hundred sixty-nine patients who underwent open rhinoplasty between 2018-2022 were included in this retrospective study. The patients were evaluated according to the risk scoring system consisting of four parameters (skin thickness, lower lateral cartilage anatomy, amount of hump resection, and soft tissue procedures). Because of the presence of supratip deformity at the postoperative 12th month, the patients were divided into two groups: (i) without supratip deformity (n = 418) and (ii) with supratip deformity (n = 51). Statistical inferences were made regarding the development of supratip deformity by evaluating the relationship between the risk scores and the intraoperative TDP-ASA distances. RESULTS: There was a significant difference between the groups in risk scores ( P < 0.05). In cases with high-risk scores, it was calculated that the probability of developing supratip deformity decreased significantly when the TDP-ASA distance was above 7.5 mm and increased significantly when the TDP-ASA distance was below 6.5 mm. In cases with low-risk scores, it was found that the probability of developing supratip deformity was reduced considerably when the TDP-ASA distance was over 6.0 mm. CONCLUSIONS: The authors recommend keeping the TDP-ASA distance above 6.0 mm in low-risk patients and 7.5 mm in high-risk patients to avoid supratip deformity.

Septoplasty During Primary Cleft Lip Reconstruction: A Historical Perspective and Scoping Review.

BACKGROUND: Traditional surgical approaches excluded septoplasty at primary cleft lip reconstruction due to concerns about restricted nasal and midfacial growth. Modern opinion in the treatment of cleft lip has increasingly employed primary septoplasty; this scoping review and historical perspective aims to chronicle the evolution of septoplasty in patients born with cleft lip and palate and discuss current evidence. METHODS: The historical perspective explicitly contrasts American and European perceptions of septoplasty in cleft lip deformity and the competing anatomical theories of the role of the septum on midfacial and nasal growth. For the scoping review, articles were extracted from Embase, PubMed, and Medline, as well as manual searches of reference lists. Results were compiled, grouped, and appraised by date, outcomes, and historical significance. Inclusion criteria consisted of children who underwent primary septoplasty for any indication and were followed up on outcomes of facial growth and nasal function. Literature reviews, opinion articles, case reports, guidelines, or studies not available in English or online were excluded. RESULTS: Evolving anatomical theories relating to midfacial growth in the mid-late 20th century underpinned a progressive ideological shift on the safety and efficacy of septoplasty in children. This is supported by our scoping review, which included 23 articles mutually selected for inclusion by 2 blinded assessors. Several competing methods have been employed to measure endpoints on facial growth and nasal function, but generally indicate primary septoplasty is successful in improving nasal function and preserving midfacial growth. CONCLUSION: Perceptions towards septoplasty on facial growth in the pediatric population have transformed significantly and suggest a growing acceptance of primary septoplasty techniques in patients born with a cleft lip.

Evaluation of osteomeatal complex by cone-beam computed tomography in patients with maxillary sinus pathology and nasal septum deviation.

BACKGROUND: This study aimed to determine if there is a relationship between the presence of maxillary sinus pathology, nasal septum deviation and various lengths of the osteomeatal complex. METHODS: A total of 223 CBCT images were included in the study. The lengths of the osteomeatal complex (maxillary sinus ostium width, infundibulum length, maxillary sinus ostium height) were analyzed. The presence of maxillary sinus pathology, nasal septum deviation, age, sex, right-left, septum deviation level, and the relationship between pathology level and all variables were evaluated. RESULTS: The average maxillary sinus ostium width, ostium height and infundibulum length were 3.06 ± 0.70 mm, 30.10 ± 5.43 mm and 8.82 ± 1.86 mm, respectively. Ostium width was significantly higher in the healthy group than in the groups evaluated in the presence of deviation and pathology. A significant difference was found in infundibulum length only between the healthy condition and the condition evaluated in the presence of deviation. No significant difference was observed between the groups in terms of ostium height. In all groups, ostium height and infundibulum length were significantly higher in men than in women. The age group with the highest average ostium height was found in the 35-44 age group (p < 0.001). CONCLUSION: Identifying normal and abnormal conditions in the osteomeatal complex area is important for diagnosing the cause of a patient's complaint, guiding the surgical procedures to be performed, and preventing possible complications that may arise during surgical procedures.

An adjoint-based approach for the surgical correction of nasal septal deviations.

Deviations of the septal wall are widespread anatomic anomalies of the human nose; they vary significantly in shape and location, and often cause the obstruction of the nasal airways. When severe, septal deviations need to be surgically corrected by ear-nose-throat (ENT) specialists. Septoplasty, however, has a low success rate, owing to the lack of suitable standardized clinical tools for assessing type and severity of obstructions, and for surgery planning. Moreover, the restoration of a perfectly straight septal wall is often impossible and possibly unnecessary. This paper introduces a procedure, based on advanced patient-specific Computational Fluid Dynamics (CFD) simulations, to support ENT surgeons in septoplasty planning. The method hinges upon the theory of adjoint-based optimization, and minimizes a cost function that indirectly accounts for viscous losses. A sensitivity map is computed on the mucosal wall to provide the surgeon with a simple quantification of how much tissue removal at each location would contribute to easing the obstruction. The optimization procedure is applied to three representative nasal anatomies, reconstructed from CT scans of patients affected by complex septal deviations. The computed sensitivity consistently identifies all the anomalies correctly. Virtual surgery, i.e. morphing of the anatomies according to the computed sensitivity, confirms that the characteristics of the nasal airflow improve significantly after small anatomy changes derived from adjoint-based optimization.

Role of Sinonasal Anatomic Variants in Recurrent Acute Rhinosinusitis.

OBJECTIVES: Prior studies evaluating the role of sinonasal anatomic variants with recurrent acute rhinosinusitis (RARS) are limited by inconsistent results. The goal of this study is to evaluate the association between sinonasal anatomic variants and RARS. METHODS: A 1:2 retrospective case-control study was conducted using patients presenting to the rhinology clinic from August 2020 to January 2023. A total of 60 patients with RARS were compared to 120 control patients. RARS was diagnosed based on the International Consensus Statement on Allergy and Rhinology criteria of four or more independent episodes of acute rhinosinusitis per year with at least one episode documented by objective findings, with complete resolution of the infection in-between episodes. Sinonasal anatomic variants included nasal septal deviation (NSD), concha bullosa (CB), infraorbital (Haller) cells, nasal septal spur in the middle meatus, and frontal sinus cells (supra-agger, supra-agger frontal, and suprabullar frontal cells). RESULTS: Age was similar in RARS and control patients (47.4 ± 16.5 vs. 49.3 ± 14.5, p = 0.432). Both the RARS group and control group were more likely to be female (78.3% vs. 77.5%, p = 0.899). There was no significant association between NSD and RARS compared to the control group (OR = 0.97, p = 0.916), and no significant association between any of the anatomic variants and RARS [infraorbital cells (OR = 0.64, p = 0.167), CB (OR = 0.84, p = 0.596), spur in the middle meatus (OR = 1.28, p = 0.514), supra-agger (OR = 0.88, p = 0.708), supra-agger frontal cells (OR = 0.97, p = 0.939), or suprabullar frontal cells (OR = 1.13, p = 0.766)]. CONCLUSION: Our findings suggest no association between nasal septal deviation or any of the anatomic variants studied and RARS. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3489-3492, 2024.

Modified extracorporeal septoplasty: prospective study.

OBJECTIVES: This study aimed to evaluate quality-of-life and satisfaction outcomes in patients undergoing the MES using the Portuguese version of the Nasal Obstruction Symptom Evaluation (NOSE-p) and Rhinoplasty Outcome Evaluation (ROE), and also to evaluate the frequency of possible complications of this technique. METHODS: We conducted a single-center prospective study with patients who had the indication for MES, from May 2016 to September 2020 at the Facial Plastic Surgery Clinic of Otolaryngology Department of the Hospital de Clinicas de Porto Alegre. The primary outcome was the relative postoperative change in NOSE-p. Secondary outcome was the variation in ROE, a validated quality-of-life questionnaire for rhinoplasty patients. RESULTS: Of the 31 patients submitted to extracorporeal septorhinoplasty who were evaluated, twenty-seven patients were included. Preoperative and postoperative NOSE-p scale scores were 65.2 ±â€¯29.9 and 23.5 ±â€¯26.7, respectively (mean differences of 42.04; [95% CI 27.35-56.73]; p <  0.0001). Pre and postoperative ROE scores were 38.3 ± 24.3 vs. 67.29 ± 29.7, respectively (mean differences of -29.02; [95% CI -40.5 to -17.5]; p =  0.0001). Residual septal deviation was verified in 2 patients (7.4%). CONCLUSION: Most of the patients submitted to modified extracorporeal septoplasty had a significant improvement in quality of life scores of nasal obstruction, with good aesthetical outcomes and low indices of postoperative complications. LEVEL OF EVIDENCE: Level 3.

Correlation of maximal nasal septal deviation with deviation at the maxillary insertion.

PURPOSE: It is unclear if septal deviation at the insertion points to the nasal cavity is associated with the overall septal deviation. This study aimed to assess septal deviation at the cribriform plate (CP) and maxillary crest (MC) using CT scans and to see if there was any correlation with overall septal deviation. METHODS: All consecutive CT sinus scans between January 2020 and December 2021 were retrospectively reviewed. Patients were excluded if they had a history of head, nasal or facial trauma, or any previous nasal surgical procedure. Angles between the septum and MC and the septum and CP as well as maximal angle of septal deviation (MSD) were measured. RESULTS: A total of 70 scans were included in the final analysis. The mean MSD was 8.14°. The mean septal deviation was 0.89° at the CP and 2.02° at the MC. The correlation coefficient between the deviation at the CP and MSD was 0.025 and between the deviation at the MC and MSD was 0.321. CONCLUSION: Our data reveal a positive correlation between septal deviation at the floor of the nose and overall septal deviation; this was not observed at the septal deviation at the roof. This could be explained due to the inherent tilt in the cribriform plate or by earlier ossification and fixation of the septum during its development at its insertion to the roof, thereby allowing further growth and potential for deviation of the lower part of the septum and its insertion to the floor.

Secondary Bilateral Cleft Rhinoplasty: Achieving an Aesthetic Result.

BACKGROUND: Secondary rhinoplasty in patients with bilateral cleft lip poses ongoing challenges and requires a reliable method for achieving optimal outcomes. OBJECTIVES: The purpose of this study was to establish a safe and effective method for secondary bilateral cleft rhinoplasty. METHODS: A consecutive series of 92 skeletally matured patients with bilateral cleft lip and nasal deformity were included. All had undergone secondary open rhinoplasty, performed by a single surgeon with a bilateral reverse-U flap and septal extension graft, between 2013 and 2021. Medical records of these 92 patients were reviewed to assess the clinical course. A 3-dimensional (3D) anthropometric analysis and panel assessment of 32 patients were performed to evaluate the aesthetic improvement, with an age-, sex-, and ethnicity-matched normal control group for comparisons. RESULTS: The methods showed statistically significant improvement in addressing a short columella (columellar height), short nasal bridge (nasal bridge length), de-projected nasal tip (nasal tip projection, nasal dorsum angle), poorly defined nasal tip (nasal tip angle, dome height, and panel assessment), and transversely oriented nostrils (columellar height, alar width, nostril type). Importantly, these improvements were accompanied by a low complication rate of 4%. However, upper lip deficiency over the upper lip angle and labial-columellar angle remained without significant improvement. CONCLUSIONS: In this study we described effective secondary rhinoplasty, which was composed of a bilateral reverse-U flap and septal extension graft, with acceptable outcome. The 3D anthropometric analysis and panel assessment clarified that our rhinoplasty procedure could bring the nasal morphology in these patients closer to the normal data.

Olfactory cleft stenosis and obstruction on paranasal sinus CT scan in pre-septo-rhinoplasty patients: normal variants or pathologic findings?

OBJECTIVE(S): To determine the frequency of olfactory cleft (OC) stenosis and obstruction on paranasal sinus CT scans in pre-septorhinoplasty of patients who had septal deviation, septopyramidal deformation or nasal obstruction without other sinonasal conditions. METHODS: This retrospective study included patients referred to our institution between December 2013 and December 2021 for septorhinoplasty due to nasal obstruction without other sinonasal or neurological conditions. All patients underwent preoperative paranasal sinus CT scan and olfactory testing. OC stenosis was quoted as none, partial, or total (less than 1/3 contact between nasal septum and ethmoid turbinates, 1/3-2/3, more than 2/3, respectively), as well as OC obstruction as none, partial, or complete (obstruction of less than 1/3 of OC, 1/3-2/3, more than 2/3, respectively). Radiologic evaluation was validated by near perfect interobserver agreement. RESULTS: A total of 75 patients (32 women, 43 men) with a mean age of 44.2 ± 15.64 (23-74) years were included, of which 36 were normosmic and 39 hyposmic. OC stenosis was partial in 58.7% (n = 44) of the patients, absent in 28% (n = 21), and total in 13.3% (n = 10), without difference between normosmic and hyposmic patients (p = .66). OC obstruction was absent in 52% (n = 39) and partial in 46.7% (n = 35), without difference between normosmic and hyposmic patients (p = .51). Only one normosmic patient had complete OC obstruction. CONCLUSION: OC partial stenosis and partial obstruction were frequent findings in pre-septorhinoplasty patients without respiratory mucosa disease and did not influence their olfactory status. Total stenosis and complete obstruction were rarer and require further investigation. CLINICAL RELEVANCE STATEMENT: Isolated partial olfactory cleft stenosis and obstruction should be considered normal variants, whereas the impact of complete olfactory cleft stenosis and obstruction on patient's olfactory status remains to be determined. KEY POINTS: • The incidence of olfactory cleft stenosis and obstruction in asymptomatic patients remains unknown, even though it is encountered in clinical practice. • Partial and total olfactory cleft stenosis occurred in 58.7% and 13.3% of the patients; partial obstruction occurred in half of the cases, but complete obstruction was extremely rare. • There are frequent findings of partial olfactory cleft obstruction and stenosis, but complete obstruction and total stenosis should be further investigated.

Functional assessment of septo(rhino)plasty revision surgery.

INTRODUCTION: Functional septo(rhino)plasty incurs a 17-25% rate of revision for persistent symptoms. OBJECTIVES: The main study objective was to assess functional results before and after surgical revision. The secondary objective was to describe the shortcomings or excesses of the prior surgeries, with a-posteriori comparison of efficacy for the surgical techniques requiring revision. MATERIAL AND METHODS: A single-center retrospective study included functional salvage septo(rhino)plasties. Data comprised epidemiology, intraoperative anatomic abnormalities indicative of prior surgery, operative correction maneuvers, and pre- and post-intervention NOSE and RhinoQoL scores and satisfaction on VAS. RESULTS: Eighty-two patients were included. Anatomic abnormalities comprised deviated posterior septum (81.7%) and chondroethmoidal junction (58.5%), valve stenosis (54.9%), and obstructive boney spur or crest (46.3%). Prior surgeries comprised 33 submucosal resections, 29 septorhinoplasties, 14 Cottle septoplasties and 5 Killian procedures. Complete septoplasty was performed in 80% of cases, with associated maneuvers in 15%. All scores showed improvement taking the whole population together (P<10-5), but on subgroup analysis improvement concerned only revision of septorhinoplasty (P<10-4) and of submucosal resection (P<10-3), while 17% of patients showed no change in scores. CONCLUSION: Functional nasoseptal salvage surgery enables most patients to recover respiratory comfort, with the exception of a few cases despite a perfectly straight nasal septum.

The Morphological and Functional Effects of the Endoscope-Assisted One-Stage Approach for Crooked Nose.

BACKGROUND: A crooked nose is an external nose deformity predominantly caused by congenital aplasia or acquired secondary to trauma or surgery, often accompanied by a deviated nasal septum. Patients with crooked nose have dual needs to improve both esthetic and functional problems. METHODS: The clinical and photographic information of 48 patients diagnosed with a crooked nose and nasal septum deviation treated from January 2018 to January 2022 was acquired. The morphology and functional effects were investigated by evaluating the general condition of the operation, measuring the esthetic indexes of the nose, and subjectively scoring. RESULTS: For both morphology and function, endoscopy-assisted one-stage correction showed positive results in this study. The external nose deviation distance postoperatively measured 1.28 (0.85, 1.97) mm, which significantly decreased from the preoperative value of 3.96 (3.31, 5.29) mm. The scores of doctors and irrelevant medical students on nose morphology increased significantly from 4.75±1.88 and 3.84±0.76 to 6.48±1.21 and 7.21±0.67, respectively. The rhinoplasty outcome evaluation score and the "nasal obstruction symptom evaluation "score of patients were both significantly improved ( t = -7.508 and t =6.310, respectively, P < 0.001). CONCLUSION: Endoscope-assisted one-stage correction of the crooked nose can restore nasal morphology, improve the symptoms of nasal obstruction, and achieve patient satisfaction. It is a minimally invasive, safe, effective, and fast recovery approach for patients who need to solve both esthetic and functional problems.

Septal Reconstruction: Simple to Complex.

Nasal septal deviation is a frequent problem treated by otolaryngologists and facial plastic surgeons. Complete correction of the septal deformity is often essential both for straightening a crooked nose and for restoration of the nasal airway. While standard septoplasty techniques provide excellent outcomes in most patients, severe septal deformities may require treatment with more advanced maneuvers including adjacent grafting, caudal septal replacement, and even extracorporeal septoplasty. This article reviews a range of septoplasty techniques, with an emphasis on complex septal reconstruction and approaches that can be utilized to maintain keystone stability and establish a robust midline L-strut even in cases with challenging anatomy.

The Effect of Trans-Sutural Distraction Osteogenesis on Nasal Bone, Nasal Septum, and Nasal Airway in the Treatment for Midfacial Hypoplasia in Growing Patients.

The purposes of this study were to analyze the effect of trans-sutural distraction osteogenesis (TSDO) on nasal bone, nasal septum, and nasal airway in the treatment of midfacial hypoplasia. A total of 29 growing patients with midfacial hypoplasia who underwent TSDO by a single surgeon were enrolled. The 3-dimensional measurement of nasal bone and nasal septum changes was performed using computed tomography (CT) images obtained preoperatively (T0) and postoperatively (T1). One patient was selected to establish 3-dimensional finite element models to simulate the characteristics of nasal airflow field before and after traction. After traction, the nasal bone moved forward significantly ( P <0.01). The septal deviation angle was lower than that before traction (14.43±4.70 versus 16.86 ±4.59 degrees) ( P <0.01). The length of the anterior and posterior margin of the vomer increased by 21.4% ( P <0.01) and 27.6% ( P <0.01), respectively, after TSDO. The length of the posterior margin of the perpendicular plate of ethmoid increased ( P <0.05). The length of the posterior inferior and the posterior superior margin of the nasal septum cartilage increased ( P <0.01) after traction. The cross-sectional area of nasal airway on the deviated side of nasal septum increased by 23.0% after traction ( P <0.05). The analysis of nasal airflow field showed that the pressure and velocity of nasal airflow and the nasal resistance decreased. In conclusion, TSDO can promote the growth of the midface, especially nasal septum, and increase the nasal space. Furthermore, TSDO is conductive to improve nasal septum deviation and decrease nasal airway resistance.

Double Opposing U Suture For Septal Multiple Axis Deviations: A Multi-Vectoral Approach.

Septal cartilage deviations comprise the majority of deformities related to revision rhinoplasty operations. Therefore, the primary operation should be as eventless and durable as possible. Many techniques have been suggested, but most present with a monoplanar correction and fixation of the septum. This study aims to demonstrate a suture method that fixates and broadens the deviated septum. This method employs a single-stranded suture passing below the spinal periosteum, pulling the posterior and anterior portions of the septal base separately. It was utilized in 1578 patients, of which only 36 necessitated a revision of septoplasty in the past 11 years (2010-2021). With a revision rate of 2.29%, this method should be considered a preferable choice over many techniques described in the literature.

Nasal Bifidity: An Unusual Pediatric Congenital Anomaly and Review of the Literature.

Congenital nasal anomalies are rare, with an estimated incidence of 1/20,000 to 40,000 live births. Hyperplasia and duplication anomalies are the most uncommon, comprising about 1% of reported cases. The authors present the case of a 6-year-old girl who presented to our institution with an isolated congenital bifid nasal septum. Parents reported a visibly abnormal nose since birth, and it had been continuously monitored by the parents and pediatrician. She demonstrated no history of difficulty breathing or other nasal concerns and was otherwise growing and developing normally. On physical examination, she was breathing comfortably through her bilateral nasal airways. Her nasal examination revealed a widened mid-vault with deep dorsal grooving and a bifid tip. Magnetic resonance imaging demonstrated an isolated bifid nasal septum without other facial malformation or intracranial extension. She underwent an open septorhinoplasty. Intraoperatively, the authors identified an anomalous dorsal nasal bone extension with a resultant bifidity in the body and caudal portions of the septum. Ostectomy and cartilaginous repositioning allowed for an autogenous reconstruction without the need for grafting. She subsequently recovered well without postoperative complications and continues to have improved nasal appearance with maintenance of function. A review of recent literatures revealed 2 other cases that are similar in presentation. The authors proposed that embryologically there might have been a change in expression of bone morphogenetic protein in the frontonasal area leading to caudal extension of the nasal bone. This in turn interferes with the fusion of nasal septum resulting in the bifid septum and dual dome morphology.

The Key to a Straight Nose Is a Straight Septum: 10 Essential Steps.

SUMMARY: The deviated nose derives from underlying skeletal and soft-tissue deformities in the upper, middle, and/or lower third of the nose. Although deviation may stem from several intrinsic and extrinsic elements, the septum is most often the primary contributor. Attempts to straighten the nose without properly addressing the septum invariably result in a persistently deviated nose. The goal of this article is to review the 10 key steps for a reliable, methodical approach to correcting the deviated septum in primary rhinoplasty.
