Presenting Symptomatology for Patients With Nasal Septal Perforation: Application of the NOSE-Perf Scale.

OBJECTIVE: To objectively identify and quantitate presenting nasal symptoms in patients with a septal perforation using the validated NOSE-Perf scale. STUDY DESIGN: Case series retrospective review. METHODS: The medical records from August 2018 through January 2022 of patients at a tertiary care academic center with a septal perforation, and who completed the NOSE-Perf questionnaire, were reviewed. Perforation symptoms were identified and quantified using the 12-item NOSE-Perf scale (score range 0-48). NOSE-Perf findings were correlated to patient demographics, perforation etiology, and perforation length. NOSE-Perf scores of patients who pursued treatment were compared with those who did not. RESULTS: NOSE-Perf data were collected from 202 patients. Nasal crusting was noted in 94.1% of patients and was the most severe symptom reported (mean 2.9 of 4.0). Nasal congestion, difficulty breathing, and nasal obstruction followed in prevalence and severity. The mean total NOSE-Perf score was 23.7. Linear regression analysis demonstrated a weakly negative association of NOSE-Perf score with patient age and weakly positive association with increasing perforation length. NOSE-Perf scores were significantly higher in women and in patients pursuing treatment. CONCLUSION: This is the first study to use the validated NOSE-Perf scale to objectively characterize and establish baseline septal perforation symptomatology. The NOSE-Perf scale can play a role in the standardization of perforation evaluation and treatment outcomes assessment. Laryngoscope, 133:1315-1320, 2023.

Analysis of patient- and procedure-related risk factors for nasal septal perforations following septoplasty.

OBJECTIVES: To assess the possible relationship between various predictive factors (patient or surgery related) and the development of nasal septal perforations (NSP) with the help of a large study group. METHODS: One hundred and forty-three patients were included in the study. The presence of the following factors was evaluated and compared between the NSP and healthy group: types of surgeries, presence of unilateral or bilateral mucosal tears, concomitant inferior turbinate interventions, smoking, accompanying diabetes mellitus (DM) or allergic rhinitis (AR), types of nasal packings, duration of the surgery (minutes), and the experience of the surgeon (senior/junior). Nasal septal deviations were grouped into two: simple cartilage crests at the septum base and other-more complicated-deviations. RESULTS: NSP was detected in six (4.2%) patients after a mean follow-up of 9.3 ± 3.7 (min: 6 max: 14) months. None of these patients suffered from (AR) or DM. Four of these patients had unilateral and one patient had bilateral mucosal tears during the surgeries. None of the above-mentioned factors-including mucosal tears, type of the deviation or experience of the surgeon-had a significant effect on NSP. CONCLUSION: Untreated bilateral corresponding mucosal tears are the main cause of NSP. When immediately repaired, unilateral or bilateral tears do not affect the development of NSP significantly. Patient-related factors such as age, DM, smoking, AR, and procedure-related factors such as duration, the complexity of the septal deviation, type of the nasal packing, and experience of the surgeon also do not have a significant effect on NSP.

Correlation of sinonasal symptoms with the size and position of nasal septal perforations.

OBJECTIVE: To assess the correlation of sinonasal symptoms and quality of life with size and position of nasal septal perforation (NSP). METHOD: This is a prospective observational study in a tertiary referral center involving adult patients presented with NSP. The Sino-Nasal Outcome Test-22 (SNOT-22) and its clinico-psychometric domains were analyzed, including additional NSP-specific symptoms (nasal crusting, epistaxis, and whistling noise during nasal breathing). The size of NSP was measured radiologically by calculating the area in cm2 and anteroposterior (AP) diameter. Position of perforation was determined clinically by distance from columella to the anterior edge of the perforation. RESULTS: Forty patients were included in this study (22 males). The most common etiology of NSP was iatrogenic. The mean SNOT-22 score was 50.8 (standard deviation 23.8), and mean NSP size was 3.0 cm2 . No statistical correlation was observed between the total SNOT-22 score with either position or size of NSP. As for NSP-specific symptoms, there was a statistically significant negative correlation with the size of perforation (A-P diameter) (r = -0.34, P = 0.03) and position of the perforation (r = -0.49, P = 0.0016), suggesting that these symptoms improved with posterior and larger perforations. CONCLUSION: Reported SNOT-22 scores were comparable to patients with recalcitrant chronic rhinosinusitis, although the scores did not correlate with size and position of NSP. Sinonasal symptoms typically observed in NSP improved with more posteriorly placed and larger sized perforations. This study provides an insight into the quality-of-life impact of NSP and affirms the clinical observation that anterior NSP are more symptomatic. LEVEL OF EVIDENCE: 4 Laryngoscope, 2019.

A computational fluid dynamics analysis of the effects of size and shape of anterior nasal septal perforations.

BACKGROUND: Nasal septal perforations (NSPs) often cause bleeding, crusting, obstruction, and/or whistling. The objective was to analyze the impact of anterior NSP size and shape on nasal physiology using computational fluid dynamics (CFD). METHODS: A 3-dimensional model of the nasal cavity was constructed from a radiologically normal CT scan using imaging software. Anterior NSPs (ovoid (ONSP): 0.5, 1, 2, and 3 cm long anterior-to-posteriorly and round (RNSP, 0.5 and 1 cm)) were virtually created in the model and divided into ventral, dorsal, anterior, and posterior regions. Steady-state inspiratory airflow, heat, and water vapor transport were simulated using Fluent CFD software. Air crossover through the perforation, wall shear, heat flux, water vapor flux, resistance, and humidification were analyzed. RESULTS: Air crossover and wall shear increased with perforation size. Regionally, wall shear and heat and water vapor flux were highest posteriorly and lowest anteriorly, generally increasing with size in those regions. RNSPs had greater heat and water vapor flux compared to corresponding size ONSPs. Resistance decreased by 10% or more from normal only in the 3 cm ONSP. Maximum water content was achieved more posteriorly in larger NSP nasal cavities. CONCLUSIONS: High wall shear and heat and water vapor flux in posterior perforation regions may explain the crusting most commonly noted on posterior NSP edges. This preliminary study suggests that larger NSPs have a greater effect on nasal resistance and water content. Decrease in resistance with larger NSP size may be implicated in reported symptomatic improvement following enlargement of NSPs for treatment.

Sino-Nasal Outcome Test-22 quality-of-life patterns in patients presenting with nasal septal perforation.

OBJECTIVES: To assess the impact of nasal septal perforation (NSP) on quality of life. DESIGN: Retrospective cohort study. SETTING: Rhinology clinics from two hospitals in Liverpool, United Kingdom. PARTICIPANTS: Patients diagnosed with NSP. MAIN OUTCOME MEASURES: Patients (n = 26) diagnosed with NSP completed the Sino-Nasal Outcome Test-22 (SNOT-22). The collated data were compared with SNOT-22 scores from a cohort of healthy volunteers (n = 34) and a cohort of patients (n = 30) diagnosed with chronic rhinosinusitis (CRS). RESULTS: The mean total SNOT-22 score of NSP and CRS cohorts was higher than that observed in healthy volunteers. The mean total SNOT-22 score in the CRS cohort (57.2, standard deviation SD 10.3) was the higher than NSP (50.2, SD 23.5), although this difference did not achieve statistical significance. The mean score for the rhinologic-specific domains (rhinologic symptoms, extranasal rhinologic symptoms), ear/facial symptoms and psychological dysfunction domain was higher in the CRS cohort compared to NSP, although statistical significance was only observed in the extranasal rhinologic symptoms domain (11.2, SD 2.4 vs 6.4, SD 4.1). Conversely, the mean sleep dysfunction domain score for NSP (12.7, SD 7.5) was higher than CRS (10.0, SD 4.9, respectively) although this was not statistically significant. CONCLUSIONS: This study has assessed the clinimetric and psychometric properties of patients suffering from symptomatic NSP. Future reports should consider inclusion of SNOT-22 data but with the addition of perforation-specific symptoms (nasal crusting, epistaxis, whistling noise).

Numerical simulation of humidification and heating during inspiration in nose models with three different located septal perforations.

Nasal septum perforations (SP) are characterized by nasal obstruction, bleeding and crusting. The disturbed heating and humidification of the inhaled air are important factors, which cause these symptoms due to a disturbed airflow. Numerical simulations offer a great potential to avoid these limitations and to provide valid data. The aim of the study was to simulate the humidification and heating of the inhaled air in digital nose models with three different SPs and without SP. Four realistic bilateral nose models based on a multi-slice CT scan were created. The SP were located anterior caudal, anterior cranial and posterior caudal. One model was without SP. A numerical simulation was performed. Boundary conditions were based on previous in vivo measurements. Heating and humidification of the inhaled air were displayed, analyzed in each model and compared to each other. Anterior caudal SPs cause a disturbed decrease of temperature and humidity of the inhaled air. The reduced temperature and humidity values can still be shown in the posterior nose. The anterior cranial and the posterior caudal perforation have only a minor influence on heating and humidification. A reduced humidification and heating of the air can be shown by numerical simulations due to SP depending on their localization. The anterior caudal SP representing a typical localization after previous surgery has the biggest influence on heating and humidification. The results explain the typical symptoms such as crusting by drying-out the nasal mucosa. The size and the localization of the SP are essential for the symptoms.

Olfaction improvement after nasal septal perforation repair with the "cross-stealing" technique.

BACKGROUND: The surgical treatment of nasal septal perforation is known to improve nasal respiratory airflow and, thereby, should be beneficial to the patient's olfactory abilities. However, there are only limited data on the effect of nasal septal perforation repair (NSPR) on olfaction, and most studies reported contradictory results. OBJECTIVE: The aim of this prospective study was to investigate the change in the olfactory abilities of 42 patients with a primary concern of nasal septal perforation. METHODS: NSPR was performed with the "cross-stealing" technique. The inferior-based mucoperichondrial flap in one side and the superior-based mucoperichondrial flap from the other side of the nasal septum were passed to the opposite sides through the perforation. Surgery was completed by placing an interpositional graft between the flaps before suturing. The interpositional grafts were residual cartilage. The olfactory performance of the patients before and at 1, 3, and 6 months after the closure of the nasal septal perforation was measured by using an olfaction test kit. RESULTS: The success rate with complete closure of nasal septal perforation with the "cross-stealing" technique was 92.8%. Analysis of the data indicated statistically significant improvement in olfactory function scored as odor threshold (T), odor discrimination (D), odor identification (I) and TDI at 1, 3, and 6 months after NSPR (p < 0.001 for all). The mean TDI score evaluated 6 months after NSPR was improved by 64%. Analyses of variance indicated statistically significant improvement in olfactory scores within time factors were calculated as preoperative versus 1, 3, and 6 months; 1 versus 3 and 6 months; and 3 versus 6 months (p < 0.001 for all). Analysis of the present data indicates a beneficial effect of NSPR on olfactory abilities of patients with perforation. CONCLUSION: Our data on the short- and long-term olfactory abilities of 42 patients with nasal septal perforation after NSPR when using an olfaction test kit indicated statistically significant improvement in olfactory function.

Nasal septal perforation reconstruction with superior-based pedicled nasolabial island flap in a patient with the Raynaud phenomenon.

Perforation of the nasal septum may have multiple causes, and there are lots of options for reconstruction. We discuss a septal perforation case with Raynaud phenomenon.

Risk factors for recurrent spontaneous epistaxis.

OBJECTIVE: To identify risk factors associated with spontaneous recurrent epistaxis. PATIENTS AND METHODS: This was a retrospective cohort study assessing patients in the Marshfield Clinic system diagnosed as having epistaxis between January 1, 1991, and January 1, 2011. There were 461 cases with at least 2 episodes of spontaneous epistaxis within 3 years and 912 controls with only 1 episode in the same time frame. More than 50 potential risk factors were investigated, including demographic features, substance use, nasal anatomical abnormalities, nasal infectious and inflammatory processes, medical comorbidities, medications, and laboratory values. A Cox proportional hazards regression modeling approach was used to calculate hazard ratios of epistaxis recurrence. RESULTS: Traditional risk factors for epistaxis, including nasal perforation, nasal septum deviation, rhinitis, sinusitis, and upper respiratory tract infection, did not increase the risk of recurrence. Significant risk factors for recurrent epistaxis included congestive heart failure, diabetes mellitus, hypertension, and a history of anemia. Warfarin use increased the risk of recurrence, independent of international normalized ratio. Aspirin and clopidogrel were not found to increase the risk of recurrence. Few major adverse cardiovascular events were observed within 30 days of the first epistaxis event. CONCLUSION: Congestive heart failure is an underappreciated risk factor for recurrent epistaxis. Hypertension and diabetes mellitus may induce atherosclerotic changes in the nasal vessels, making them friable and more at risk for bleeding. Patients with recurrent epistaxis may also be more susceptible to developing anemia. Physicians should promote antiplatelet and antithrombotic medication adherence despite an increased propensity for recurrent epistaxis to prevent major adverse cardiovascular events.

Nasal septal perforation repair using intranasal rotation and advancement flaps.

BACKGROUND: We aimed to present our experience with and algorithm for septal perforation repair using advancement and rotation flaps. METHODS: A retrospective chart review was performed on 14 patients who underwent septal perforation repair. Etiology, perforation size, presenting symptoms, reconstruction methods, combined operation, surgical results, and complications were evaluated. RESULTS: The mean postoperative follow-up duration was 36 ± 18 months. Among 14 cases, 9 had previous septoplasty or septorhinoplasty and 5 cases suffered from nasal trauma. The perforation sizes varied from 5 to 27 mm, with a 14-mm average. Two cases had multiple perforations. The main symptoms included nasal obstruction, crusting, epistaxis, and whistling. Perforations were repaired using advancement flaps in seven cases or combination of advancement and rotation flaps in seven cases, with or without an interposition graft. Bilateral mucosal closure was accomplished in all cases. Conchal cartilage, remnant septal cartilage, or septal bone was used for an interposition graft. Nine patients had a concurrent rhinoplasty with septal perforation repair. At last follow-up, complete perforation closure was achieved in 12 cases (85.7%). Septal perforation recurred in 2 large perforation cases, which were repaired without interposition grafts. Nasal symptoms disappeared or improved in 13 cases (92.9%). There were no serious complications after surgery. CONCLUSION: Combined use of intranasal advancement and rotation flaps is a safe and promising option for surgical repair of moderate to large septal perforation. Bilateral tension-free mucosal closure with an interposition graft is important for the surgical success.
