Septal perforation

Aim: This study isolates septal perforations due to nasal surgery for clinical analysis and their effect on bilateral mucosal flap repair. Methods: This is a retrospective review of a single surgeon’s 20-year experience with endonasal perforation repair utilizing bilateral mucosal advancement flaps supported with an autologous tissue interposition graft. Patients with a minimum of 4-month postoperative follow-up were included in the study. Comparative analyses of repair failure rates and perforation size of failures between surgical and non-surgical etiologies were performed. Results: Three hundred ninety-two patients met the criteria for inclusion in the study. The incidence of perforation and prior septal surgery was 40.6%. Overall repair closure in patients with a minimum of 4 months follow-up was 94.8%. Failures were noted in 5.7% of surgical and 4.7% of non-surgical perforation etiologies (P = 0.816). Mean differences in perforation length and height in failed repairs between non-surgical and surgical etiologies (19.4 vs. 13.7 and 15.5 vs. 9.3 mm, respectively) were significant (P = 0.048 length, P = 0.006 height). Conclusion: Post-surgical nasal septal perforations can be repaired with a low rate of failure. However, this study found that the size of perforations in failed repairs was significantly smaller in patients with a history of septal surgery, suggesting that prior septal surgery increases the technical difficulty of a bilateral flap perforation repair.

Effect of Remimazolam on the Incidence of Intraoperative Hypothermia Compared with Inhalation Anesthetics in Patients Undergoing Endoscopic Nasal Surgery: A Prospective Randomized Controlled Trial.

Remimazolam is an ultrashort-acting benzodiazepine that is increasingly used for its efficacy in anesthesia induction and maintenance. However, limited research has explored its impact on intraoperative hypothermia compared to that of traditional inhalation anesthetics. This study aimed to compare the incidence of hypothermia during endoscopic nasal surgery when using remimazolam for maintenance anesthesia versus using inhalation anesthetics. This prospective study included 70 patients who underwent endoscopic nasal surgery under general anesthesia. The patients were randomly assigned to one of two groups: the inhalation anesthetic (IA) group (n=35), in which desflurane and nitrous oxide were administered, and the remimazolam (R) group (n=35), in which remimazolam and remifentanil were administered for anesthesia maintenance. The primary outcome was the incidence of intraoperative hypothermia, defined as an esophageal temperature below 36 °C during anesthesia. The incidence of intraoperative hypothermia was significantly higher in the R group than in the IA group (P = 0.014). Furthermore, the temperature at the end of the surgery was significantly lower in the R group than in the IA group (P = 0.006). Additionally, the use of warming devices after surgery was more frequent in the R group than in the IA group (P = 0.047). These findings suggest that the use of remimazolam for maintenance anesthesia during endoscopic nasal surgery increases the risk of intraoperative hypothermia compared to the use of inhalation anesthetics. This highlights the importance of temperature monitoring in patients receiving remimazolam to minimize the adverse outcomes associated with hypothermia during surgery.

Auricular conchal cartilage for treatment of empty nose syndrome

Empty nose syndrome is an uncommon complication of turbinoplasty and other nasal operations. It presents with various manifestations, with the most common symptom being paradoxical nasal obstruction. Here, we report the case of a 67-year-old male patient diagnosed with empty nose syndrome 20 years after turbinoplasty. Autologous auricular conchal cartilage was harvested and implanted into the lateral wall of the inferior turbinate to reduce nasal volume. The patient experienced significant relief from subjective nasal obstruction symptoms immediately after surgery. Over a 23-month follow-up period, no side effects or symptom recurrence was reported.

Management of Nodular Nasal Basal Cell Carcinoma with Wide Excision, Transpositional Median Forehead Flap, Forehead Split Thickness Skin Graft: Case Report

Introduction: Basal cell carcinoma (BCC) is the most common skin type cancer with an incidence rate of around 75-80%. The most common location is in the head and neck area around 70-80% and followed by other body parts around 25% consist of the penis, vulva or perianal area and 5% on the skin. BCC occurs more frequently in light-skinned individuals compared to dark-skinned individuals. The incidence rate is relatively lower in Asians, blacks ethnic, and Hispanics.
 Case Presentation: A 66 years-old woman complained of scabs on the right side of her nose which had become increasingly widespread for the past 2 years. The wound was initially the size of a mole and was scratched until it spread until the patient was hospitalized. Physical examination showed a wound in the nasal area measuring 4 x 5 x 1 cm, irregular wound edges, cartilaginous wound base with necrotic tissue and pus. The first biopsy examination showed poorly differentiated basal cell carcinoma. The patient was treated with Nasal Reconstruction surgery consisting of wide excision was performed by surgical oncologist, transpositional median forehead Flap and forehead Split Thickness Skin Graft were performed by reconstructive plastic surgeon.
 Discussion: The diagnosis of BCC in this patient was based on regarding history taking, physical examination and histopathological examination. However, for defects with a diameter of more than 1.5 to 2 cm, generally recommended using axial pattern flaps such as forehead flaps, nasolabial flaps and dorsal nose flaps. In this case, the patient was treated with wide excision followed by nasal reconstruction with a transpositional forehead flap and forehead split thickness skin graft.
 Conclusion: Nevertheless, regional flaps remain the recommended procedure for nasal reconstruction after wide excision of the tumor. Accurate analysis of the damage combined with evaluation of the patient's clinical condition is necessary to select the best surgical technique. Thorough knowledge of regional vascular anatomy and a comprehensive multidisciplinary approach are important first steps for proper treatment of nasal skin cancer, so that the procedure for wide excision of nasal basal cell carcinoma followed by nasal reconstruction with transpositional forehead flap and split thickness skin graft, can provide satisfactory result.

An Analysis of the VELNEZ Nasal Pack's Acceptability and Safety for Use During Nasal Surgery: A Prospective Study.

The primary function of nasal packs is to modulate the bleeding, prevent adhesions and obstruction, with least discomfort to the subjects without risking secondary infection. However, both packing and removal of the pack is an unpleasant experience, with the latter being extremely painful. Therefore the need of the hour is a dressing which prioritizes subject comfort without compromising other desired nasal pack properties.Twenty subjects were enrolled in this interventional, open label study. The subjects had 10 hospital visits, starting from baseline (Visit 1) to postoperative day 28 (Visit 10), at regular intervals. The proportion of the population with postoperative pain alleviation and bleeding control failure (within 10min) were the main objectives. Within 10min of VELNEZ administration, all 20 participants got their bleeding under control. With VELNEZ, the painful nasal pack removal method was totally avoided because it was biodegradable. No moderate/severe pain, infection and adhesions were reported in any of the subjects, but few subjects reported moderate obstruction until Visit 3 (Discharge Day). In the present study, for participants undergoing nasal surgery, VELNEZ proved to be a secure and reliable nasal pack. Trial Registration: CTRI/2021/09/036437, prospectively registered.

Comprehensive measurement of obstruction in nasal allergen challenges—a critical update

Numerous methods for functional diagnostics of nasal obstruction provide various information on nasal airway resistance and may aim to replace physically based methods by so-called simplifications or solely on subjective score systems. This may lead to nonsatisfying results in nasal surgery and prolonged postoperative care. An interdisciplinary analysis of contemporary methods for measurement was the task of the German-Austrian research program “Rhinodiagnost”. This review is intended to discuss basic and wide-spread errors playing a significant role during daily practice and proposes a step program for functional rhinological diagnostics with some modifications to be applied in case of allergic nasal disease. With regard to the content of “position paper on the standardization of nasal allergen challenges (2018)” of the European Academy of Allergology and Clinical Immunology (EAACI) and the results of the consensus conference of Riga in 2016, the differences between of “classic” and 4-phase-rhinomanometry (4PR) and their differences are clarified. The parameters of logarithmic effective resistance (LReff) allow a classification of the obstruction obtained during 36,500 measurements which are correlated to the subjective sensing of obstruction. The classification can be adapted for age and size and is valid for the Caucasian and Chinese populations.

Epidemiology of postoperative bleeding after endoscopic nasal and sinus surgery and factors associated with bleeding

PurposeEndoscopic nasal and sinus surgery is a surgical procedure frequently performed by otolaryngologists. Postoperative bleeding is detrimental to both healthcare providers and patients. We investigated the epidemiology of postoperative bleeding during endoscopic nasal and sinus surgery and explored possible bleeding triggers.MethodsWe evaluated the patients who underwent endoscopic nasal and sinus surgery. Data regarding the age, sex, presence of hypertension, and abnormal coagulability, including oral anticoagulants, diagnoses, operative procedures, intraoperative use of drills and blood loss, and postoperative antimicrobial administration of eligible patients, were extracted from medical records and retrospectively reviewed.ResultsOne hundred and eighty-six patients underwent endoscopic nasal or sinus surgery during the study period, and postoperative bleeding occurred in 9 patients (4.8%). Posterior nasal neurotomy (PNN) was the procedure most likely to cause postoperative bleeding (4 surgeries, 13.3%). Postoperative antimicrobial administration significantly reduced the incidence of postoperative bleeding (p = 0.04).ConclusionsPostoperative bleeding requiring intervention occurs in 4.8% of cases, and PNN is associated with a high risk of postoperative bleeding. Wound infection is a potential cause of postoperative bleeding, and antimicrobial administration should be considered in addition to local treatment.

Trends in Nasal Septal and Inferior Turbinate Surgery in Korea From 2010 to 2022

Background and Objectives: Since the introduction of nasal valve surgery, trends in septoplasty and inferior turbinate surgery (ITS) have changed in Korea. However, a detailed analysis of these changes has yet to be conducted.Methods: Data on septoplasty and ITS performed from 2010 to 2022 were extracted from the Health Insurance Review and Assessment Service (HIRA) Bigdata Open portal and trends were analyzed. Analyses according to the type of medical institution, patient sex and age, and the specialty of the surgeon were also conducted.Results: The frequency of both septoplasty and ITS gradually decreased from 2012 to 2017, which marked the low point, and the frequency of these procedures gradually increased thereafter. In 2010, 41.5% of septoplasty procedures were performed in general hospitals, 7.3% in hospitals, and 47.3% in clinics. However, the proportion of these procedures performed in general hospitals subsequently decreased, while the corresponding proportion in hospitals and clinics increased. Both septoplasty and ITS were performed more than twice as often in men than in women. The number of patients under the age of 19 decreased, while the number of female patients aged 20–29 increased. The number of septoplasty procedures performed by plastic surgeons increased.Conclusion: Since the introduction of nasal valve surgery, the number of septoplasty procedures performed by plastic surgeons has increased.

Effect of butorphanol-soaked nasal packing after endoscopic nasal surgery: a double-blind, randomized, placebo-controlled trial

ObjectiveThis study was designed to investigate the effect of butorphanol-soaked nasal packing on analgesia and sleep quality in patients undergoing bilateral endoscopic nasal surgery. MethodsSixty-six patients were enrolled and randomly allocated into three groups: group B1 (butorphanol 0.03mg/kg), group B2 (butorphanol 0.04mg/kg) and group N (control group). The primary outcome was postoperative pain scores evaluated by a Visual Analogue Scale (VAS) at 2h (T1), 8h (T2), 24h (T3) and 48h (T4) after surgery. Secondary outcome was postoperative sleep quality measured using Subjective Sleep Quality Value (SSQV). ResultsPostoperative VAS scores of butorphanol groups were significantly lower than the control group at T2, T3 and T4. VAS scores at each time point did not differ between groups B1 and B2. On the first and second nights after surgery, SSQV was higher in butorphanol groups than in the control group. There were no significant differences in SSQV1 and SSQV2 between group B1 and group B2. The incidence of respiratory depression, dizziness, agitation and rescue analgesic use did not show difference among three groups. ConclusionsButorphanol-soaked nasal packing can reduce pain and improve sleep quality after bilateral endoscopic nasal surgery without increasing adverse effects. A concentration of 0.03mg/kg may be appropriate for clinical application. Level of EvidenceLevel 1B.

Artificial Intelligence Versus Expert Plastic Surgeon: Comparative Study Shows ChatGPT "Wins" Rhinoplasty Consultations: Should We Be Worried?

Introduction: Large language models, such as ChatGPT, hold tremendous promise to bridge gaps in patient education and enhance the decision-making resources available online for patients seeking nasal surgery. Objective: To compare the performance of ChatGPT in answering preoperative and postoperative patient questions related to septorhinoplasty. Methods: Two sets of responses were collected for the questions: one from an expert rhinoplasty surgeon with over two decades of experience, and the other from ChatGPT-3.5. Seven expert rhinoplasty surgeons, blinded to the source of responses, independently assessed the responses using a 5-point Likert scale in four performance areas: empathy, accuracy, completeness, and overall quality. Results: ChatGPT outperformed physician responses in three of the four performance areas, earning significantly higher ratings in accuracy, completeness, and overall quality (p < 0.001). In addition, ChatGPT was overwhelmingly preferred over physician responses (p < 0.001), with evaluators favoring ChatGPT in 80.95% of instances. Conclusions: ChatGPT has demonstrated its remarkable ability to deliver accurate, complete, and high-quality responses to preoperative and postoperative patient questions. Although certain improvements are warranted, this artificial intelligence tool has shown its potential to effectively counsel and educate prospective septorhinoplasty patients at a level comparable with or exceeding that of an expert surgeon.

Fitostimoline® in fibro-endoscopic and trans-nasal trans-speculum septoplasty as a beneficial tool to improve post-surgical outcome: Preliminary results of a case-control study

ObjectivesTopic treatment can be useful to improve short and long-term nasal outcomes after nasal surgery, reducing discomfort and risk of synechia. This study aimed at evaluating the effect on clinical outcomes of nasal packaging using Fitostimoline® gauze in FESS and septoplasty. MethodsA case-control study on hospitalized patients was performed in a tertiary referral center. The control group included 20 patients treated with the standard surgical protocol for septoplasty and standard nasal packaging; treatment group included 21 patients underwent same surgical procedure but in whom the nasal tampon was wrapped with a gauze containing Fitostimoline® before being placed into the nose. ResultsPatients in treatment group had better outcomes than control; nasal mucosa showed better healing - recovery of normal color- in those patients in whom we applied the Fitostimoline® gauze around tampons. Moreover, 100 % patients in the treatment group did not refer discomfort during at tampon removal versus 60 % subjects in the control group who referred pain, tension or tearing during the same action. ConclusionOur results, although preliminary because of the small cohort of subjects included, suggest that the apposition of a gauze with Fitostimoline® after nasal surgery might improve the mucosal healing with consequent reduction of patients discomfort during the post-surgical period.

Do Children with Previous COVID Infection Have Hyposmia?

Our goal was to see if children with a history of COVID infection had subclinical hyposmia. Consecutive patients at a pediatric otolaryngology clinic aged 5-17 years were recruited. Demographics including gender, race, use of nasal topical medications (NTM), previous nasal surgery including adenoidectomy (NSA), and previous COVID-19 infection were collected. Each child performed a test of their sense of smell using the Pediatric Smell Wheel (PSW, Sensonics Intl, USA) under the direct supervision and scores were compared. 260 children were included; mean age 10.1 years (95% CI 9.7-10.5), 128 (49.2%) female and 132 (50.8%) male. 65 (25%) used steroid nasal sprays, 100 (38.5%) had undergone adenoidectomy, and 36 (13.8%) had other nasal surgery. 120 (46.2%) had a previous COVID-19 infection. The COVID+ and COVID- groups were the same for age, gender, race, use of NTMs, and previous NSA (p > 0.05). Mean PSW score was 7.8 (95% CI 7.6-8.0), median of 8, ranging from 2 to 11. The mean PSW score was 8.0 for the COVID- group and 7.6 for the COVID+ group (p = 0.005). There was no significant difference in total PSW scores based on gender, race, use of NTMs, previous NSA. Linear regression showed previous COVID infection was significantly negatively associated with total PSW score (Beta -0.636, p = 0.006) with age significantly positively associated (Beta 0.122, p < 0.001). Children with a history of COVID infection performed slightly worse when identifying odors than children without a COVID history. More study into the rates of pediatric anosmia related to COVID infection is needed. 3 Laryngoscope, 134:901-906, 2024.

The predicting role of postoperative changes in self-reported symptoms in patients with recurrence eosinophilic chronic sinusitis with nasal polyps

Objective:To investigate whether changes in postoperative symptoms and signs in patients can predict the recurrence of ECRS after nasal endoscopic sinus surgery. Methods:A total of 70 adult patients with ECRS were enrolled for ESS surgery from June 2020 to March 2022 in a single center. There were 50 males and 20 females, with an average age of （46.9±14.5） years. Follow-up after ESS was at least 52 weeks. Patients undergo peripheral blood tests, CT of the sinuses, olfactory T&T test, visual analogue scale of symptoms（VAS）, and endoscopic scoring. Results:VAS scores and endoscopic scores were analyzed at preoperative and 6th week, 12th week, 24th week and 52th week postoperative. After 12th week postoperatively, there was a clear correlation between symptom scores and endoscopic scores. Moreover, olfactory disorder and nasal discharge were the two most obvious symptoms. There were differences in the expression of multiple preoperative clinical inflammatory indicators between the symptom-controled group and the symptom-uncontrolled group（previous surgical history, concomitant asthma, nasal smear eosinophil, serum EOS%, total IgE, CT score, olfactory score, and symptom score, all with P<0.05）, while there was no difference in baseline endoscopic score（P>0.05）. At 12th week postoperative, the two groups of patients showed significant differences in both symptom scores and endoscopic scores. The symptoms and endoscopic score at the 12th week point of follow-up were used as predictive indicators for recurrence, with sensitivity and specificity of 62.5% and 83.3%, respectively. Conclusion:The changes in postoperative symptom score and endoscopic score in ECRSwNP patients indicated that the recurred ECRS. In the symptom-uncontrolled group, symptomatic and endoscopic scores showed consistent increased scores; In the symptom-controlled group, conflicting results between increased endoscopic scores and stable symptoms suggest that the presence of asymptomatic recurrence must be considered. The changes in symptoms and signs at the 12th week point of follow-up can serve as clinical indicators for preventing disease recurrence.

Differential expression of NEDD8 in different pathological types of chronic rhinosinusitis with nasal polyps

Objective:To analyze the differential expression of neural precursor cell-expressed developmentally downregulated 8（NEDD8） protein in nasal polyp tissues of patients with different pathological types of chronic rhinorhinosinusitis with nasal polyps（CRSwNP）. Methods:All specimens were obtained from the specimen library of Beijing Tongren Hospital, and were all patients who underwent nasal endoscopic surgery for chronic rhinosinusitis in Beijing Tongren Hospital. Hematoxylin-eosin staining（HE） was used to detect the number of eosinophils in nasal polyps, and CRSwNP patients were grouped according to the number of eosinophils in nasal polyps, immunohistochemistry was used to detect and analyze the expression level of NEDD8 protein in nasal polyps. Results:The expression level of NEDD8 protein in nasal polyps of patients with eosinophilic chronic rhinorhinosinusitis with nasal polyps was significantly higher than that of patients with non-eosinophilic chronic rhinosinusitis and nasal polyps（P<0.05）. In addition, there was a significant positive correlation between the expression level of NEDD8 protein and the number of eosinophils in nasal polyp tissue（r=0.79, P=0.02）. Conclusion:There are differences in the expression of NEDD8 protein in patients with chronic rhinosinusitis and nasal polyps of different pathological types.

Artificial intelligence-assisted prediction of olfactory disorders in patients with chronic rhinosinusitis

Objective:To analyze the influencing factors and perform the prediction of olfactory disorders in patients with chronic rhinosinusitis（CRS） based on artificial intelligence. Methods:The data of 75 patients with CRS who underwent nasal endoscopic surgery from October 2021 to February 2023 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. There were 53 males and 22 females enrolled in the study, with a median age of 42.0 years old. The CRS intelligent microscope interpretation system was used to calculate the proportion of area glands and blood vessels occupy in the pathological sections of each patient, and the absolute value and proportion of eosinophils, lymphocytes, plasma cells and neutrophils. The patients were grouped according to the results of the Sniffin' Sticks smell test, and the clinical baseline data, differences in nasal mucosal histopathological characteristics, laboratory test indicators and sinus CT were compared between the groups. Determine the independent influencing factors of olfactory disorders and receiver operating characteristic curves（ROC） were used to evaluate the performance of the prediction model. Statistical analysis was performed using SPSS 25.0 software. Results:Among the 75 CRS patients, 25 cases（33.3%） had normal olfaction and 50 cases（66.7%） had olfactory disorders. Multivariate Logistic regression analysis showed that tissue eosinophils percentage（OR=1.032, 95%CI 1.002-1.064, P=0.036）, Questionnaire of olfactory disorders-Negative statement（QOD-NS）（OR=1.079, 95%CI 1.004-1.160, P=0.040） and Anterior olfactory cleft score（AOCS）（OR=2.672, 95%CI 1.480-4.827, P=0.001） were independent risk factors for olfactory disorders in CRS patients. Further research found that the area under the ROC curve（AUC） of the combined prediction model established by the tissue eosinophil percentage, QOD-NS and AOCS was 0.836（95%CI 0.748-0.924, P<0.001）, which is better than the above single factor prediction model in predicting olfactory disorders in CRS. Conclusion:Based on pathological artificial intelligence, tissue eosinophil percentage, QOD-NS and AOCS are independent risk factors for olfactory disorders in CRS patients, and the combination of the three factors has a good predictive effect on CRS olfactory disorders.

Investigation of the effects of nasal surgery on nasal cavity flow using magnetic resonance velocimetry and computational fluid dynamics

The nasal cavity has the function of conditioning the air inhaled into the lungs by heating, humidifying, and filtering dust and virus-borne aerosols. Analyzing the flow field in the nasal cavity is vital because its function is strongly related to flow dynamics. Due to experimental limitations posed by the complex internal geometry of the nasal cavity, most previous studies have utilized Reynolds averaged Navier–Stokes based computational fluid dynamics (CFD) simulations. In this study, the flow field in a post-operative nasal cavity was evaluated using not only CFD simulations but also four-dimensional magnetic resonance velocimetry. The study was conducted under resting breathing conditions in pre- and post-operative models of a patient who received septoplasty and turbinoplasty. The experimental results confirmed balanced flow rates in the left and right nasal cavities after septoplasty and a decrease in velocity after turbinoplasty with a reduction in regions with vortices and reverse flow. Upon comparison, CFD results using the laminar, k–ω, and shear stress transport models were deemed to be consistent with the experimental results. However, there was a relatively large deviation observed with the k–ε model. Using the validated laminar CFD model, it was shown that the pressure and wall shear stress decreased after surgery.
