Efficacy and safety of turbinate reduction surgery in children: a systematic review.

PURPOSE: Inferior turbinate hypertrophy is not a rare problem in children, it causes chronic nasal obstruction which can severely impact the quality of life. This study aimed to investigate the efficacy and safety of turbinate reduction surgery in children with impaired nasal breathing due to hypertrophied inferior turbinate that's refractory to medical treatment. METHODS: We included 23 articles with various study designs: randomized controlled trials, single-arm clinical trials, and prospective and retrospective cohort studies. We searched PubMed, Scopus, Cochrane Library, and Web of Science with the relevant keywords till April 9th, 2023. The inclusion criteria were studied with the three prespecified study design that addressed children under 18 years who underwent turbinate reduction with any technique and evaluating the improvement whether by objective or subjective methods. RESULTS: Studies used objective measures favor turbinate surgery except two that showed no significant difference between pre and postoperative results. All studies used subjective measures showed an improvement postoperatively except one study. Complication rates are rare, with crust formation is being the commonest (6.03%), however, the procedure is generally safe in children. In addition, follow-up periods varied widely between 2 weeks and more than 5 years. CONCLUSION: Turbinate reduction in children is an effective as a treatment method for nasal blockage due to inferior turbinate hypertrophy which is resistant to medical treatment. It is a safe procedure with low rates of complications, however, due to the heterogenicity of the study designs, with a possible risk of bias we could not conduct a meta-analysis besides our systematic review.

Efficacy and safety of middle turbinate surgery: a systematic review.

PURPOSE: Middle turbinate (MT) surgery is extremely common during endoscopic sinus surgery procedures, though no agreement exists on which techniques provide the best outcomes. This PRISMA-compliant systematic review aims to assess which MT surgery technique yields the least postoperative adverse effects and the best objective and subjective outcomes. METHODS: A comprehensive search criteria was conducted in multiple databases up to July 3, 2023, to identify studies reporting surgical treatments of the MT. After screening and quality assessment, 14 articles were included for analysis. Data on patients demographics, surgical approaches, postoperative treatment and follow-up, objective and subjective outcomes were extracted and reviewed. RESULTS: Out of 173 unique papers identified, 14 articles met the inclusion criteria, predominantly randomized controlled trials (n = 9). Antero-inferior middle turbinectomy was the predominant surgical approach. Most studies evaluated results with postoperative endoscopy, a superior outcome was documented in the intervention group (ten out of eleven cases). In four out five studies using the SNOT-22, the treatment group was associated with a statistically significant improvement. Olfactory questionnaires highlighted superior olfactory outcome in two out of three studies. The UPSIT score revealed no significant difference between groups. Objective olfactory assessments favored treatment groups in both studies utilizing olfactometry. CONCLUSIONS: It seems that a partial MT surgical approach consistently yields subjective and objective improvements compared to conservative measures, also suggesting a positive impact on smell function. Despite it appears that better outcomes with fewer complications are consistently achieved with partial techniques, it remains challenging identifying which partial technique surpasses the others, due to significant heterogeneity among the studies.

The submucosal approach influences long-term outcomes of refractory obstructive rhinitis: A prospective study and a STROBE analysis.

OBJECTIVE: The surgical approach to refractory hypertrophy of the inferior turbinates is the main therapeutic choice in the management of its symptoms. Although submucosal approaches have demonstrated efficacy, long-term results are debated in the literature and show variable stability. Therefore, we compared the long-term outcomes of three submucosal turbinoplasty methods with regard to the efficacy and stability managing the respiratory disorders. DESIGN: Multicenter prospective controlled study. A computer-generated table was used to allocate participants to the treatment. SETTING: Two teaching and university medical centers. METHODS: We used the EQUATOR network for guidelines describing design, conduct, and reporting of studies and searched the references of these guidelines to identify further relevant publications reporting adequate study protocols. Patients with persistent bilateral nasal obstruction due to lower turbinate hypertrophy were prospectively recruited from our ENT units. Participants were randomly assigned to each treatment and then underwent symptom assessment by visual analog scales, endoscopic assessment at baseline and 12, 24 and 36 months after treatment. RESULTS: Of the 189 patients with bilateral persistent nasal obstruction initially assessed, 105 met the study requirements; 35 were located in the MAT group, 35 in the CAT group and 35 in the RAT group. Nasal discomfort was significantly reduced after 12 months with all the methods. The MAT group presented better outcomes for all VAS scores at the 1-year follow-up, greater stability at the 3-year follow-up for VAS results (p < 0.001 in all cases) and lower disease recurrence (5/35; 14.28 %). At the 3-year follow-up intergroup analysis, a statistically significant difference was confirmed except for RAA scores (H = 2.88; p = 0.236). Rhinorrhea (r = -0.400; p < 0.001) was demonstrated as a predictive factor of 3-year recurrence, while sneezing (r = -0.25; p = 0.011), and operative time needed (r = -0.23; p = 0.016) did not reach statistical significance. CONCLUSIONS: Long-term symptomatic stability varies depending on the turbinoplasty method used. MAT demonstrated greater efficacy in controlling nasal symptoms, presenting better stability in reducing turbinate size and nasal symptoms. In contrast, radiofrequency techniques presented a higher rate of disease recurrence both symptomatically and endoscopically.

Effectiveness of submucosal turbinoplasty in refractory obstructive rhinitis: a prospective comparative trial.

OBJECTIVE: Refractory inferior turbinate hypertrophy requires a surgical approach to address symptomatic complaints. Submucosal approaches demonstrated their efficacy in restoring respiratory function and respecting the nasal mucosa. Microdebrider-assisted turbinoplasty (MAT) tools effectively reduces the soft tissue, exploiting a very different principle from the kinetic energy of radiofrequency. Thus, we aimed to compare the microdebrider-assisted turbinoplasty and the quantum molecular resonance (QMR) to assess patients' perspectives and respiratory outcomes. METHODS: Subjects with persistent bilateral nasal blockage due to inferior turbinates hypertrophy were prospectively recruited from the University Medical Center. We randomly assigned the patients to each treatment and performed symptom evaluation via the visual analog score and endoscopic assessment at baseline and 30-, 90-, and 180-day post-treatment. RESULTS: Seventy participants completed the evaluations, 35 in MAT and 35 in the QMR group. Nasal complaints were significantly reduced after 1 month using both methods. Although the MAT group reported higher postoperative bleeding and edema than QMR group, similar significant reductions were seen for turbinate size at long-term follow-up. Conversely, the MAT group reported greater VAS outcomes than QMR from the first postoperative month. In addition, MAT showed a longer operating time, although this difference was not statistically significant (p < 0.05). CONCLUSION: MAT allows effective control of nasal symptoms by reducing the size of turbinates in patients with lower turbinate hypertrophy. Although QMR may cause fewer postoperative complications, functional results are comparable to long-term follow-up.

Piezo-assisted Turbinoplasty Versus Partial Turbinectomy in External Septorhinoplasty: A Prospective Comparative Study in 100 Patients.

OBJECTIVES: The purpose of this study was to compare the outcome of the piezo-assisted turbinoplasty with a partial turbinectomy technique in the treatment of chronic nasal obstruction due to inferior turbinate enlargement. STUDY DESIGN: This is a prospective randomized single-center study in a cohort of 100 consecutive patients which underwent external septorhinoplasty and concomitant hybrid type of turbinoplasty. METHODOLOGY: Patients were randomly assigned into two groups. The first group included 50 patients who underwent piezo-assisted outfracturing of the inferior turbinates in combination with bipolar coagulation. The second group included 50 patients who underwent a treatment based on turbinate bipolar coagulation and partial resection of the inferior border of the turbinate. The severity of nasal obstruction was measured in both patient groups with a patient-related outcome questionnaire (NOSE) and objective measures (anterior rhinomanometry and acoustic rhinometry). Assessments were conducted prior to surgery and 3 months after the surgery. RESULTS: There was a significant improvement in the values of the NOSE questionnaire with no relevant difference between the two study groups. Acoustic rhinometry and rhinomanometry also showed no statistically significant differences between the two study groups. No differences in postoperative healing were found, and postoperative complications were comparable low in both groups. However, the piezo-assisted procedure was quicker to perform with only minimal bleeding. CONCLUSION: During septorhinoplasty, the combination of thermo-coagulation with piezo-assisted turbinoplasty was as efficient as with partial turbinectomy to establish normal nasal breathing.

Surgery to relieve nasal obstruction: outcome for 366 patients operated on by one senior surgeon.

BACKGROUND: Studies of patient-rated outcome in septoplasty and turbinoplasty most frequently involve several surgeons with varying surgical skills, techniques and experience. The aim of the present study was to evaluate outcome based on one experienced surgeon. METHODS: Three hundred and sixty-six consecutive patients referred for nasal obstruction were included. All the patients were examined with nasal endoscopy before and after decongestion, they filled out a nose VAS and rated their overall general health before and three to six months after surgery. The patients underwent septoplasty, septoplasty plus turbinoplasty or turbinoplasty. RESULTS: The mean nose VAS for nasal obstruction (0-100) preoperatively was 64.7 for all patients. Patients undergoing septoplasty (n = 159) were younger than patients undergoing septoplasty + turbinoplasty (n = 79) or patients undergoing turbinoplasty alone (n = 128). The nose VAS for nasal obstruction improved significantly in all three groups and 25% had a normal nose VAS after surgery in the septoplasty and septoplasty + turbinoplasty groups compared to only 8% in the turbinoplasty alone group. There was no significant difference in the improvement in nasal obstruction between septoplasty and septoplasty + turbinoplasty, but the septoplasty + turbinoplasty group experienced a significantly greater improvement in general health. CONCLUSIONS: In 366 patients operated on by one experienced surgeon, septoplasty and septoplasty + turbinoplasty were more effective at relieving nasal obstruction than turbinoplasty alone. Septoplasty + turbinoplasty resulted in a greater improvement in general health than septoplasty alone, despite the same improvement in nasal obstruction, indicating a beneficial effect of additional turbinoplasty in septoplasty.

Comparison of efficacy of potassium titanyl phosphate laser & diode laser in the management of inferior turbinate hypertrophy: A randomized controlled trial.

Background & objectives: Inferior turbinate hypertrophy (ITH) is a common condition causing nasal obstruction. This study was undertaken to compare the efficacy of potassium titanyl phosphate (KTP) laser and diode laser in the reduction of the turbinate size. Methods: This randomized controlled trial included 209 patients with ITH. Pre-operative symptoms were assessed based on the Nasal Obstruction Symptom Evaluation (NOSE) score. Diagnostic nasal endoscopy was done to rule out other nasal sinuses. Nasal mucociliary clearance was measured by saccharin transit time (STT). Postoperatively, the NOSE score, STT and complications were assessed at days one and two, at one week, one month and three months. Results: Of the 209 patients analyzed at day one, the median NOSE score was 50 in the diode group and 40 in the KTP group, and at three months, 15 in the diode group and five in the KTP group. KTP laser showed a 93 per cent improvement in the NOSE score as compared to 77 per cent improvement shown by diode laser group. Among the intra-operative complications, of the 104 patients in the diode group, 6.73 per cent had burning sensation and 91.43 per cent had bleeding, and of 105 patients in the KTP group, 54.29 per cent had burning sensation and 36.54 per cent had bleeding. Among the post-operative complications in the KTP group, 32 and 34 per cent had bloody nasal discharge on days one and two, compared to 12 and 14 per cent in diode group. Crusting was present in 61 and 49 per cent on days one and two in KTP group as compared to 9 and 15 per cent in diode group, respectively. In the KTP group 30 per cent had synechiae as compared to 10 per cent in diode group. Interpretation & conclusions: KTP laser was more efficacious than diode laser in improving the NOSE scores but with slightly increased rate of complications in early post-operative period. Both the lasers impaired the mucociliary clearance mechanism of the nose till three months of post-operative follow up.

Radiological comparison of inferior turbinate hypertrophy between allergic and non-allergic rhinitis: does allergy really augment turbinate hypertrophy?

BACKGROUND: Inferior turbinate hypertrophy could be a result of allergic rhinitis (AR) that leads to nasal congestion and nasal airway obstruction, which is the most bothersome complaint in patients with AR. However, evidence regarding whether patients with AR have a more hypertrophied inferior turbinate than do patients with non-AR is lacking. OBJECTIVE: We aimed to evaluate the degree of inferior turbinate hypertrophy according to the presence of AR using radiological measurements of the inferior turbinate. METHODS: For evaluating the inferior turbinate, which contributes to nasal obstruction in patients with AR, we enrolled 90 adult patients with septal deviation and divided them into two groups (AR group: n = 49; non-AR group: n = 41). Allergic rhinitis was diagnosed according to the presence of an allergic history, positive multiple allergen simultaneous test, and serological total immunoglobulin E level (≥ 100 kU/L). We analyzed the minimal cross-sectional area on acoustic rhinometry for both groups. The bilateral total width as well as medial mucosa and nasal cavity space in the anterior and posterior portions of the inferior turbinate were measured using computed tomography. RESULTS: We could not find any significant differences in the anterior and posterior dimensions of the inferior turbinate, intranasal space, and choanal spaces between the AR and non-AR groups. Instead, the anterior part of the inferior turbinate in both the groups showed significant differences between the deviated and contralateral sides. The contralateral side had a larger width than did the deviated side, but no significant difference was noted in the posterior portion of the inferior turbinate. CONCLUSION: The degree of inferior turbinate hypertrophy showed no difference between patients with and without AR. Therefore, we suggest that surgical treatment for reducing the size of the inferior turbinate hypertrophy should be considered when performing septoplasty in patients with symptoms of nasal obstruction, regardless of the presence of AR.

Simultaneous Rhinoseptoplasty and Orthognathic Surgery: Outcome Analysis of 250 Consecutive Patients Using a Modified Le Fort I Osteotomy.

BACKGROUND: The purpose of the present study was to assess the safety and efficacy of both functional intranasal procedures and cosmetic rhinoplasty combined with bimaxillary surgery. METHODS: The author executed a retrospective cohort study derived from patients who underwent combined rhinoseptoplasty and bimaxillary surgery at a private practice setting (Face Surgery Center, Parma, Italy) between April 2006 and 2015 by a single surgeon. The minimum follow-up was 12 months. Patients underwent bimaxillary orthognathic surgery, functional nasal surgery and cosmetic rhinoplasty. RESULTS: Two-hundred and fifty (250) consecutive, non-randomized patients met the inclusion criteria to enter the study. The overall complication rate was 5%, whereas the revision rate was 9%, showing an overall low rate, comparable to that of primary rhinoplasty (control group). About 94% of the patients polled after this procedure asserted they definitely accepted to have rhinoplasty only because it was included in one single surgical act together with orthognathic surgery. CONCLUSION: Cosmetic rhinoplasty shows great potentials to change our patients' appearance, whereas orthognathic surgery corrects jaw skeletal deformities and builds the right foundation for facial harmony. The combination of both procedures magnifies the single results reciprocally and significantly enhances the final outcomes. The quality of the overall aesthetic results, the scarcity of complications and the low percentage of defects that require revisions lead to the conclusion that when alterations to both the jaws and the nose are detected, a single intervention can grant great benefit to the patients in terms of morbidity and costs.

The effect of topical 5-flurouracil application post endoscopic inferior turbinoplasty.

RATIONALE AND OBJECTIVES: Adhesions are the most common complication after nasal surgery and revision. 5-Fluorouracil (5-FU) reduces various adhesions and epithelial growth related complications. The aim of this study was to evaluate the effects of 5-flurouracil application in the nasal cavity after a multi-procedure nasal surgery in term of complications frequency. MATERIALS AND METHODOLOGY: Institutional ethical approval was granted and a double-blinded prospective clinical trial was conducted to study the effect of 5-fu on post-operative complications. At the end of a combined endoscopic inferior turbinoplasty with one or more other nasal surgeries, 5-flurouracil-soaked cottonoid with 1mL of 5-flurouracil (5mg/mL) was applied in one side of nasal cavity and saline-soaked cottonoid was applied contralaterally and left for 5min. Patients were assessed over 2months postoperatively by a blinded observer in terms of adhesions, crustation, discharge, pain, discharge, loss of smell and other complications and nasal symptoms. RESULTS: On the 1st follow up week postoperatively, adhesions were observed in (24 patients) 35%, bilateral in (6 patients) 9% and unilateral in (18 patients) 26%. Unilateral Adhesions were statistically significantly higher in control sides than those in 5-FU sides (22% vs 4% respectively) (p=0.025). Crustation, continued to statistically significantly diminish over time (p=0.035). On the 8th follow up week, adhesions reduction was still statistical significant at the 5-FU treated side (p=0.01). CONCLUSION: 5-FU is safe and effective in preventing adhesions formation when applied during combined endoscopic inferior turbinoplasty procedure with other nasal procedure surgery.

Ultrastructural regenerating features of nasal mucosa following microdebrider-assisted turbinoplasty are related to clinical recovery.

BACKGROUND: The nasal mucosa plays a key role in conditioning the inhaled air and in regulating the immune response. These functions led many authors to recommend mucosal sparing techniques for the surgical management of inferior turbinate hypertrophy. However, the histological modifications of chronic diseases retain the inflammatory activity and prevent the nasal physiology restoration. It has been proved that the basal cells of the nasal mucosa are able to proliferate and to repair after cold-knife incision. The aim of this study was to demonstrate that the healing process after removal of the inferior turbinate mucosa with cold techniques results in a complete structural restoration. METHODS: A prospective study was performed in 18 patients who underwent Microdebrider inferior turbinoplasty (cold technique). Subjective and objective improvement of nasal patency was evaluated with visual analogue scale, rhinomanometry, videoendoscopy and mucociliary transport test. Pre- and post-operative biopsy specimens were taken from 7 patients to evaluate the healing process. Two samples were taken from two healthy patients as control. The specimens were processed for transmission electron microscopy analysis. RESULTS: Videoendoscopy showed reduction of lower turbinate after surgery. Nasal patency augmented and no adverse consequences were observed. After 4 months the nasal mucosa showed normal appearance, with restoration of the pseudostratified ciliated pattern, intercellular connections and normal cellular morphology. Fibrosis and submucosal edema disappeared. At longer time after operation (4 years) clinical improvement was confirmed. CONCLUSIONS: The total removal of the nasal mucosa with cold techniques results in a complete restoration of the normal structure and permanent resolution of the chronic inflammation typical of hypertrophic rhinopathy.

Radiofrequency Coblation Versus Intramural Bipolar Cautery for the Treatment of Inferior Turbinate Hypertrophy.

OBJECTIVE: Compare intramural bipolar electrocautery and radiofrequency coblation in the treatment of inferior turbinate hypertrophy with regards to objective and subjective improvement in nasal obstruction, rate and type of complications, experience during the procedure, and rate of recovery. STUDY DESIGN: Prospective, single-blinded study. SETTING: Single tertiary medical center from 2008 to 2010. SUBJECTS AND METHODS: Forty-one adult patients with inferior turbinate hypertrophy refractory to medical management were treated with radiofrequency coblation in one nostril and intramural bipolar cautery in the other. Subjective and objective data, including use of a Visual Analog Scale (VAS) for subjective outcomes, acoustic rhinometry, and nasal endoscopy, were then obtained from each patient comparing the 2 techniques. RESULTS: Radiofrequency coblation was significantly less painful than intramural bipolar cautery during the procedure (P = .03) and during the early postoperative period (P < .02) and produced less crusting at 3 weeks (P = .009). Both interventions were similar in subjective and objective improvements in nasal obstruction as measured by acoustic rhinometry and subjective VAS outcomes. CONCLUSION: Radiofrequency coblation seems to offer an equivalent alternative to bipolar electrocautery for the treatment of inferior turbinate hypertrophy with less discomfort during the procedure and early post-operative period.

The Frequency of Concomitant Adjunctive Nasal Procedures in Powered Endoscopic Dacryocystorhinostomy.

PURPOSE: To assess the frequency of concomitant adjunctive nasal procedures performed in powered endoscopic dacryocystorhinostomy (DCR). METHODS: Retrospective review of 269 consecutive powered endoscopic DCR's performed in 202 patients over a period of 10 years from 2003 to 2013. Patient records were reviewed for demographic data, clinical profiles and surgical notes. Concomitant adjunctive procedures were studied with relation to number of patients, indications, types of procedures (septoplasty, middle turbinoplasty and functional endoscopic sinus surgery or FESS) and complications. RESULTS: 269 powered endoscopic DCR's were performed on 202 patients. The mean age at surgery was 58.4 years (range 20-91 years). Adjunctive nasal procedures were performed in 53.4% (108/202) of the patients. 47% (95/202) required a septoplasty. Among the 95 septoplasty patients, 85 required solo septoplasty and 10 had additional sinus procedure. Middle turbinoplasty was performed in 5.9% (12/202) and septal papilloma excision was performed in 0.49% (1/202). No additional morbidity was noticed with adjunctive procedures. Successful outcomes of DCR were achieved in 96.5% of patients. CONCLUSION: Simultaneous adjunctive nasal procedures were commonly required with powered endoscopic DCR. Septoplasty and middle turbinoplasty when performed as needed, provides an additional access to lacrimal region and may facilitate successful outcomes.

Facial Pain Triggered by Inferior Turbinate Partial Resection in a Patient with a Previous History of Inferior Meatal Antrostomy: A Case Report.

OBJECTIVES: Inferior meatal antrostomy (IMA) is regarded as a safe method, with minimal complications, for managing various lesions in the maxillary sinus. However, in patients with persisting IMA window, resection of the inferior turbinate may result in direct airflow into the antrum, irritating the antral mucosa. METHODS: Case report and review of literature. RESULTS/CASE: The present report describes a 29-year-old man who previously underwent unilateral IMA for the excision of a dentigerous cyst. The patient did not report any facial pain following the excision of the cyst. One year later, this patient underwent partial resection of the inferior turbinate for the resolution of nasal stuffiness by another surgeon. Soon after surgery, the patient developed severe facial and ocular pain on the side of the IMA, with the pain being especially aggravated upon inhalation. Endoscopy and computed tomography (CT) revealed a persisting IMA window. The patient's severe discomfort was thought to result from direct airflow into the maxillary sinus, as the resected turbinate may have altered normal nasal airflow. A unilateral inferior meatal augmentation procedure (IMAP) with an autologous ear cartilage implant was performed, resulting in complete relief of pain and discomfort. CONCLUSIONS: Although IMA alone is a relatively safe surgical procedure, care should be taken when performing inferior turbinoplasty in patients with persistent IMA opening.

Topical Anesthesia Versus Submucosal Injection for Radiofrequency Turbinoplasty: Same Benefit but without Patient's Pain. A Comparative Study.

This study aimed at comparing the anesthetic efficacy of lidocaine injection versus pledgets soaked in lidocaine and epinephrine during radiosurgery of inferior turbinates. The study prospectively enrolled 120 outbound patients, who were randomly assigned to group 1 -anaesthesia with tampon soaked in lidocaine and adrenaline- or group 2 -anesthesia with tampon followed by lidocaine and adrenaline injection. The following parameters were evaluated by a visual analogue scale 1 h after surgery: pain, anxiety, chocking sensation and difficulty swallowing. Nasal obstruction, rhinorrhea, sneezing, headache and inferior turbinate size were evaluated preoperatively (T0), after 1 (T1), 2 (T2) and 3 months (T3) to surgery. The data collected were analyzed by statistic tests. Group 1 showed lesser pain than group 2 during the procedure (p < 0.01); no statistically significant differences were observed for anxiety, chocking sensation and difficulty swallowing. All patients, independently from the belonging group, significantly improved the nasal symptoms comparing T0 and T1 (p < 0.01), T2 (p < 0.01) and T3 (p < 0.01), without statistically significant differences among the groups. Radiofrequency turbinoplasty allowed to all patients to reduce the turbinates hypertrophy. Local anaesthesia with tampon allowed to obtain the same results the injective anaesthesia in term of surgical outcomes; the use of tampon allowed patients did not experience pain.

A prospective histopathological analysis of the inferior turbinate: which functional parts should be preserved during turbinate surgery?

OBJECTIVE: Inferior turbinate (IT) hypertrophy-induced chronic nasal obstruction is one of the most common problems in rhinology. However, the histopathological analysis of the hypertrophic IT is unclear. Therefore, this study aimed to identify the histological changes and the most functional areas of the IT to assist otolaryngologists with improving and modifying surgical techniques and minimizing potential complications. METHODS: This prospective, cross-sectional study was conducted to evaluate the contribution of hypertrophic IT to nasal obstruction. For the analysis, a total of 38 adult patients (IT hypertrophy group and non-IT hypertrophy [control] group) were enrolled, and 131 specimens were obtained during the surgical procedures (IT hypertrophy group, endoscopic submucosal turbinoplasty and septoplasty; non-IT hypertrophy group, septoplasty). Intraoperative samples were collected from four sites of the IT to determine the dimensions, composition, and possible pathological changes in each individual site. The samples were analyzed using light microscopy. RESULTS: A comparison of the four sites of the IT in the IT hypertrophy group showed that the posterior end had the highest normal epithelium percentage, and cilia count. This suggests that preserving the functional part of the IT during surgery is crucial. Furthermore, a comparison of both groups in terms of basement membrane thickness and vessel wall thickness (p = 0.005 and p = 0.03, respectively) showed significant differences. CONCLUSION: Our findings can assist otolaryngologists select the most appropriate surgical procedures for IT hypertrophy. In addition, they advocate the importance of preserving the functional part of the IT during surgical intervention to achieve an efficiently working IT and avoid undesirable complications while improving the nasal airway passage. LEVEL OF EVIDENCE: Level 3.

Surgical Correction of Nasal Obstruction and Its Effect on Eustachian Tube Dysfunction Symptoms.

OBJECTIVES: To investigate how eustachian tube dysfunction symptoms change following surgical treatment of nonsinusitis-related nasal obstruction. STUDY DESIGN: Retrospective chart review. SETTING: Single academic center. METHODS: We assessed patients who underwent septoplasty, turbinate reduction, or both for nasal obstruction. Chronic sinusitis patients were excluded. Eustachian tube dysfunction (ETD) symptoms were studied using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7), collected preoperatively and postoperatively (1 week, 1 month, 3 months, 6 months postop). Patients with preoperative ETDQ-7 > 14.5 were considered to have clinically significant symptoms. Sinonasal outcomes test scores were also assessed. Pre- and postoperative ETDQ-7 scores were compared using t test. Multivariate linear regression analysis identified factors associated with ETDQ-7 change. RESULTS: We analyzed 259 patients. Preoperatively, 37.5% of patients with nasal obstruction had clinically significant ETD symptoms. These patients exhibited significant improvement in ETDQ-7 at all postoperative timepoints from 23.3 ± 7.6 at baseline to 19.1 ± 9.1 at 1 week, 16.5 ± 8.0 at 1 month, 16.2 ± 7.8 at 3 months, and 16.7 ± 10.4 at 6 months (all P < .01). In patients without baseline ETD symptoms, (baseline ETDQ-7: 9.1 ± 2.3) ETDQ-7 scores did not change significantly at postoperative timepoints, except for an acute worsening at 1 week postoperatively (10.7 ± 5.1, P < .001). Regression analysis showed that higher preoperative ETDQ-7 score (ß = -0.84, 95% confidence interval [CI]: -1.10 to -0.59) and postoperative antihistamine spray usage (ß = -8.70, 95% CI: -14.20 to -3.20) were associated with ETDQ-7 improvement, while comorbid GERD (ß = 7.50, 95% CI: 3.42-11.58) and asthma (ß = 5.62, 95% CI: 0.80-10.45) were negatively associated with improvement. CONCLUSION: Surgical correction of nasal obstruction may improve ETD symptoms.

Functional evaluation of Septal L-strut extension graft in East Asians.

BACKGROUND: The septal L-strut extension graft (SLEG) consists of anterior extended spreader graft and caudal septal extension graft. SLEG is used to increase the anterocaudal projection from a low-profile nose by creating the de-novo septum. This retrospective study verified the effectiveness of SLEG in improving the nasal function in East Asians. MATERIALS: Medical records of patients who underwent septorhinoplasty with SLEG were retrospectively reviewed. The clinical features showed under-projected lower two-thirds of the nose with septal deviation, saddle nose, and short nose. We analyzed the post-operative changes in the NOSE score and variables of nasal geometry measured using acoustic rhinometry through long-term follow-up. RESULTS: Patients were divided into two groups, those who underwent SLEG with turbinoplasty (Group A) and SLEG alone (group B). The NOSE scores decreased significantly in groups A and B, and the improvement was statistically more significant in Group A (p < 0.05). Acoustic rhinometry showed an increase in nasal cavity volume (VOL1) on the deviated side in Group A, and an increase in minimal cross-sectional area 1 (MCA1) on the deviated side in Group B (p < 0.05). The non-deviated side did not show significant reduction in MCA1 and VOL1 after SLEG with or without turbinoplasty. Thus, SLEG, by itself, improved airway function in East Asians. CONCLUSIONS: SLEG has proven to be valuable in improving nasal function.
