Renal cell carcinoma (RCC) is notorious for its propensity to metastasize even after a prolonged period of remission following nephrectomy. The metastatic spread can occur months or even years after initial treatment, which necessitates a heightened level of clinical awareness and vigilance in patients with a history of renal malignancy, particularly who present with new or unexplained nasal symptoms. Although RCC most commonly metastasize to the lungs, bones and liver, its involvement in the nasal cavity is exceedingly rare, posing significant diagnostic challenges due to the non-specific nature of symptoms. We describe a case of metastatic renal cell clear cell carcinoma presenting with recurrent epistaxis and unilateral nasal obstruction. Immunohistochemistry studies play a crucial role in confirming the diagnosis and ruling out potential differential diagnoses, along with a comprehensive clinical history of the patient.

OBJECTIVE: To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery. METHODS: The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation. RESULTS: All patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones ( P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied. CONCLUSION Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.

Objective: To compare the severity of symptoms of patients diagnosed with Eosinophilic Chronic Rhinosinusitis with Nasal Polyposis (eCRSwNP) versus Non - Eosinophilic Chronic Rhinosinusitis with Nasal Polyposis (non-eCRSwNP) using the Filipino Sinonasal Outcome Test (Filipino SNOT 22) and determine the most common symptoms experienced by patients with eCRSwNP versus non-eCRSwNP. : Methods Design: Cross-Sectional Study Setting: Tertiary Government Training Hospital Participants: A total of 68 patients diagnosed with Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP) from November 7, 2018 to August 31, 2022 were included in the study. Results: Of the 68 patients included in the study, 33 (48.5%) had non-eCRSwNP while 35 (51.5%) had eCRSwNP. The age of the patients with non-eCRSwNP group was 50.6 + 18.45 and those with eCRSwNP was 52.9 + 16.6 years old. Non-eCRSwNP patients had a lower mean Filipino SNOT 22 score of 39.7 ± 16.1 compared with eCRSwNP with a score of 62.7± 13.5. The non-eCRSwNP patients had symptom severity classified as mild in 2 (6.1%), moderate in 25 (75.8%) and severe in 6 (18.2%) based on Filipino SNOT-22. Among the eCRSwNP group, majority of the patients, 29 (82.9%) were classified as severe, 6 (17.1%) as moderate, and none with mild severity. Using the Filipino SNOT 22, the most common symptoms of patients with eCRSwNP were item 2 (baradong ilong; nasal blockage) at 28.6%, then item 7 (malapot na sipon; thick nasal discharge) at 25.7%, Item 8 (pagbabara ng tenga; ear fullness) and item 12 (pagkawala/ pagkabawas ng panlasa/ pang amoy; decreased sense of smell/taste) were tied at 14.3%, item 13 (hirap sa pagtulog; difficulty falling asleep) at 25.7%, and item 17 (pagkapagod; fatigue during the day) at 31.4% while patients with no-eCRSwNP were noted with item 2 (baradong ilong; nasal blockage) at 48.5%, followed by item 4 (hindi tumitigil na pagtulo ng sipon; runny nose) at 21.2%, item 11 (pananakit ng mukha; facial pain) at 33.3%, Item 7 (malapot na sipon; thick nasal discharge) at 18.2%, and item 20 (pagiging irritable/pagkainis; irritability) at 21.2%. Conclusion Our present study suggests that the higher the SNOT 22 score, the more likely it is to be eosinophilic chronic rhinosinusitis. Although nasal blockage was the most common symptom found in both patients with eCRSwNP and non-eCRSwNP, patients with thick nasal discharge, decreased sense of smell/taste and ear fullness were more likely to be suffering from eCRSwNP, while patients with runny nose, facial pain and thick nasal discharge were more likely to have non-eCRSwNP.

Objective: To present a rare case of nasal tip schwannoma and describe its resection and reconstruction using combined cartilage grafts. Methods: Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 13-year-old boy presented with a progressively enlarging nasal tip and severe left nasal obstruction causing breathing difficulties and psychosocial distress. There was a bulging septal mass obstructing 90% of the left nasal cavity. Septal incision biopsy revealed schwannoma and definitive surgery via open rhinoplasty approach was done. The non-encapsulated schwannoma extended from the subcutaneous nasal tip to the left septal mucosa. There was no evidence of skin or cartilage invasion, but prolonged pressure from the expansile schwannoma caused severe lower lateral cartilage and anterior septal atrophy leading to a collapsed and expanded nasal tip after resection. To correct this, a total reconstruction of the anterior tip complex was done using combined ear cartilage seagull wing graft, shield graft and septal extension graft. Conclusion Nasal tip and septal schwannoma is rare and can cause significant nasal obstruction and deformity. Complete excision is vital to avoid recurrence. Total reconstruction of the lower lateral cartilages using autologous septal and ear cartilage grafts may be a safe and effective technique that yields acceptable aesthetic results.

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.

Objective:To explore the expression and importance of Piezo1, E-cadherin, and Vimentin in nasal polyps patients. Methods:Thirty-five patients undergoing endoscopic sinus surgery under general anesthesia were streamed into 20 cases of nasal polyps（NP group） and 15 cases of simple septoplasty without any sinus disease（Control group）. Immunofluorescence staining and Western Blot were applied to detect the protein level of Piezo1, E-cadherin, and Vimentin in NP tissues and nasal polyp-derived primary human nasal epithelial cells（pHNECs）. Also, BEAS-2B cell lines were treated with human TGF-β1 protein to establish epithelial mesenchymal transition（EMT） model in vitro and quantitative real-time polymerase chain reaction were used to calculate Piezo1 and above biomarkers in the model. Results:Compared with control group, Piezo1 and Vimentin showed higher level while E-cadherin was lower in NP tissues and pHNECs.In EMT model in vitro, Piezo1 and Vimentin were demonstrated higher expression with decreased level of E-cadherin. Conclusion:The tendency of Piezo1 is consistent with the mesenchymal-related biomarker Vimentin, going against with epithelial-related biomarker E-cadherin, implying its involvement with EMT process in nasal polyps.

Objective:To investigate the correlation between FCER2（2206A>G） gene polymorphism and the efficacy of inhaled corticosteroids（ICS） in patients with chronic rhinosinusitis（CRS）. Methods:A total of 208 CRS patients were routinely treated with functional endonasal sinus surgery and postoperative ICS. DNA extraction, PCR amplification and gene sequencing were performed to observe the FCER2（2206A>G） gene polymorphism and calculate the allele frequency. The visual analog scale（VAS） score, Lund-Kennedy score, and computed tomography（CT） Lund-Mackay score were determined 6 months after surgery among patients with different genotypes. Moreover, the polymorphism frequency was compared among different subgroups（chronic rhinosinusitis with nasal polyps versus chronic rhinosinusitis without nasal polyps, eosinophilic chronic rhinosinusitis versus non-eosinophilic chronic rhinosinusitis）. Results:There were FCER2（2206A>G） gene polymorphism in patients with CRS, and the phenotypes included 3 genotypes, AA, AG and GG, with distribution frequencies of 68（32.7%）, 116（55.8%） and 24（11.5%） cases, respectively. No significant differences were found in age, VAS score, nasal endoscopic Lund-Kennedy score and CT imaging Lund-Mackay score among patients with CRS of each genotype before surgery. In patients with the AA genotype, the changes in VAS score（5.74±1.10）, Lund Kennedy score（5.92 ± 1.14）, and CT imaging Lund-Mackay score（13.26±4.26） were significantly higher than in patients with the AG（4.37±0.86, 5.37±1.24, 10.82±3.77） and GG（4.26±0.80, 5.18±1.56, 10.10±3.53） genotype（P<0.05）. However, there were no marked difference between patients with the AG genotype and those with the GG genotype（P>0.05）. Compared with patients with non-eosinophilic sinusitis, Among them, the differences between the GG genotype and AG /AA genes were more significant in eosinophilic sinusitis compared to non-eosinophilic sinusitis（P<0.01）. Conclusion:The FCER2（2206A>G） gene in patients with CRS has genetic polymorphism and is associated with the recovery of CRS patients after surgery, individual corticosteroid sensitivity, and subgroup variability.

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.
