Abstract Objective This study aimed to evaluate the sinonasal-related Quality of Life (QoL) in patients undergoing endoscopic skull base surgery. Methods A retrospective study was performed, including patients with benign and malignant tumors at a single institution. Each patient completed the 22-Item Sino-Nasal Outcome Test (SNOT-22) and the Empty Nose Syndrome 6 Item Questionnaires (ENS6Q) to assess their perceived QoL at least 2-months after treatment. Results Forty-nine patients were enrolled in this study. The average score was 25.1 (Stander Deviation [SD] 14.99) for SNOT-22 and 6.51 (SD = 5.58) for ENS6Q. Analysis of the overall results for the SNOT-22 showed that olfactory damage was the most serious syndrome. The most frequently reported high-severity sub-domains in SNOT-22 were nasal symptoms and sleep symptoms. Nasal crusting was the most severe item in ENS6Q according to the report. Nine patients (18.4%) had a score higher than 10.5 which indicates the high risk of Empty Nose Syndrome (ENS). SNOT-22 score was related to the history of radiotherapy (p < 0.05), while the ENS6Q score was not. Conclusions The possibility of patients suffering from ENS after nasal endoscopic skull base surgery is at a low level, although the nasal cavity structure is damaged to varying degrees. Meanwhile, patients undergoing endoscopic skull base surgery were likely to suffer nasal problems and sleep disorders. Patients who had received radiotherapy have a worse QoL than those without a history of radiotherapy. Level of evidence Level 3.

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

Método Estudo transversal exploratório de 38 imagens térmicas que representavam o momento da inspiração e da expiração durante a respiração nasal e durante a simulação da respiração oral de quatro voluntárias respiradoras nasais sem queixas respiratórias. Para a extração da temperatura das regiões de interesse (nariz e boca) foram utilizadas três formas de seleção distintas de dados (linha, retângulo e elipse) e três medidas de temperatura (mínima, média e máxima) por meio do software FLIR Tools®. Resultados Dentre as três formas de seleção houve maior variabilidade nas medidas obtidas pela linha, revelando limitações nessa medida. Não houve diferenças entre as medidas do retângulo e elipse, mostrando que ambas as formas de seleção apresentam resultados semelhantes para a extração das temperaturas. Na comparação entre as temperaturas do nariz e da boca na inspiração e expiração, os resultados indicaram que houve diferença com relevância estatística em todas as medidas realizadas, exceto para as medidas de temperatura média da inspiração, usando o retângulo e a elipse. Percebe-se diferenciação do modo respiratório tanto na inspiração quanto na expiração quando utilizada a temperatura média da boca com o retângulo e a elipse. Conclusão Sugere-se para avaliação do modo respiratório a avaliação da boca, por meio da elipse, com análise da temperatura média durante a inspiração.
ABSTRACT Purpose To present a method for analyzing breathing modes with infrared thermography. Methods This exploratory cross-sectional study used 38 thermal images of inspiration and expiration with nasal breathing and simulated mouth breathing in four nasal breathers without respiratory complaints. Three different data selection forms (line, rectangle, and ellipse) were used to extract the minimum, mean, and maximum temperatures of the regions of interest (nose and mouth) using the FLIR Tools® software. Results Among the three selection forms, there was greater temperature variability obtained with the line, revealing limitations in this measurement. There were no differences between the rectangle and ellipse values, showing that both selection forms present similar temperature extraction results. The comparison results between nose and mouth temperatures during inspiration and expiration indicated a statistically significant difference between all measurements, except for mean inspiration temperatures with the rectangle and ellipse. The breathing mode can be distinguished in both inspiration and expiration when using mean mouth temperatures with the rectangle and ellipse. Conclusion Breathing modes should be assessed based on mean mouth temperatures during inspiration, using the ellipse.

摘要
Introdução: A síndrome de Binder também pode ser conhecida como displasia maxilonasal e é uma malformação congênita caracterizada por hipoplasia nasomaxilar devido a um subdesenvolvimento do esqueleto facial médio. A atual incidência ou prevalência ainda é desconhecida, mas afeta aproximadamente um recém-nascido vivo em cada 10.000 nascimentos. O diagnóstico pode ser clínico ou associado a ultrassonografia pré-natal, caracterizada por nariz achatado e convexidade anormal da maxila. O tratamento é cirúrgico para correção das anormalidades estéticas e funcionais. Relato de Caso: Paciente que recebeu diagnóstico de síndrome de Binder aos 14 anos, sem outras malformações associadas, com queixa estética e funcional nasal. A correção cirúrgica foi iniciada pela extração de um bloco da sexta cartilagem costal à esquerda, com abertura nasal na margem columelar, no padrão de uma rinoplastia aberta, e dissecados os tecidos no plano subSMAS. Após preparo da área receptora nasal, foram esculpidos bloco de cartilagem para reconstrução do dorso nasal, enxertos alares e enxerto de cartilagem septal. Houve melhora de projeção da ponta nasal e alongamento nasal. Conclusão: A rinoplastia pode ser uma cirurgia desafiadora nesses pacientes, sendo a reconstrução autóloga com o uso de cartilagem costal indicada pela literatura como a melhor opção. É necessário individualizar cada caso para programação de enxertos e reestruturação nasal, sendo fundamental também a melhora funcional desses casos.
Introduction: Binder's syndrome can also be known as maxillonasal dysplasia and it is a congenital malformation characterized by nasomaxillary hypoplasia resulting from an underdevelopment of the middle facial skeleton. The current incidence or prevalence is still unknown, but it affects approximately one child in every 10,000 births. The diagnosis can be clinical or associated with prenatal ultrasonography, characterized by a flattened nose and abnormal maxillary convexity. The treatment is surgical to correct aesthetic and functional abnormalities. Case Report: Patient diagnosed with Binder's syndrome at the age of 14, without other associated malformations, with aesthetic and functional nasal complaints. Surgical correction began with the extraction of a block of the sixth costal cartilage on the left, with a nasal opening on the columellar margin, in the pattern of an open rhinoplasty, and tissue dissection in the sub-SMAS plane. After preparing the nasal receptor area, a block of cartilage was sculpted for reconstruction of the nasal dorsum, alar grafts and septal cartilage grafts. There was an improvement in the projection of the nasal tip and nasal dorsum. Conclusion: Rhinoplasty can be a challenging surgery in these patients, and the literature indicates that the best option is autologous reconstruction with costal cartilage. It is necessary to individualize each case to schedule nasal grafts and restructuring, and functional improvement in these cases is also essential

Myxomas are benign and locally invasive neoplasms of primitive mesenchymal origin. They are most commonly found in the atria of the heart. They have also been reported in bones, muscles, and other connective tissues. Myxomas are rarely found in the nose and paranasal sinuses. Myxomas are notorious for their recurrence after excision and local invasion. We report a case of intranasal myxoma in a 30-year-old male who presented with blocked ear sensation and progressive nasal block. With this report, we intend to increase awareness about the clinical presentation, histologic characteristics, and management options of myxoma

Background: Complementary and alternative medicine (CAM) use is highly gaining popularity along with main treatment streams these days. Physicians cannot ignore this fact and should question and counsel patients about pros and cons of CAM for cure of different ailments. Aim and Objectives: The objective of the study was to know about use of CAM among patients visiting Ear, Nose, and Throat (ENT) outpatient department (OPD) in tertiary care hospital of Southern Rajasthan. Materials and Methods: An observational cross-sectional study was conducted in ENT OPD for 2 months. Two hundred and fifty patients were considered for the study. Semi-structured questionnaire was prepared and made to be filled by the patients during their visit to ENT OPD after taking informed consent. Various questions were asked like extent of use of alternative therapies, type of CAM used by the patients, patient’s knowledge about ADRs and drug interactions, reasons for which alternative medicine might have been used. Results: Among 250 patients, CAMs were used by 36 patients. The most common CAMs were either Ayurveda or Homoeopathy medicines or both. The majority of patients obtained their information from family and friends. Maximum patients used these alternative medicines for relief of cough and hoarseness of voice. Conclusion: The study throws light on use of alternative drug therapy and streams of medicine along with routine hospital treatment among patients visiting ENT OPD. This knowledge helps to understand about patients’ alternative approach to diseases, about self-medication, patient’s belief about different types of therapies and also ignorance of possible health hazards, side effects, and complications due to use of concomitant main and alternative medicines for treatment purposes.

Abstract Introduction: Inappropriate antibiotic use in the world leads to an increase in both health care costs and antibiotic resistance. Surgical antibiotic prophylaxis (SAP) is used by most surgeons, especially in the postoperative period. Objective The aim of the study is to determine the approach of ear, nose, and throat (ENT) specialists to surgical antibiotic prophylaxis in routine surgeries, and to raise awareness regarding inappropriate antibiotic use. Methods ENT specialists from all over Turkey participated in the study by filling out a data collecting form. The form consisted of 6 questions and was sent to specialists via email. Routine ENT operations such as adenoidectomy, tonsillectomy, adenotonsillectomy, ventilation tube application, septoplasty, rhinoplasty, septorhinoplasty (non-complicated), tympanoplasty, and simple mastoidectomy were chosen for the study. Data were analyzed statistically. Results The form results of 110 ENT specialists were evaluated. The rate of participants who used and did not use SAP was 77.3% and 22.7%, respectively. The SAP usage rates of septoplasty, rhinoplasty, and septorhinoplasty operations were 84.7%, 81.2%, and 75.3%, respectively. For tympanoplasty and ventilation tube application operations, the rates were 82.4% and 24.7%, respectively. Finallly, the SAP usage rates of adenoidectomy, tonsillectomy, and adenotonsillectomy were 57.6%, 75.3%, and 72.9%, respectively. Conclusion Otolaryngological surgeries are often classified as clean or clean-contaminated surgeries. In most studies in the literature, it is reported that SAP use is unnecessary in routine otolaryngological surgery. Providing inservice training, regularly updating the prophylaxis guidelines and sharing these guidelines with surgeons may prevent inappropriate SAP use.

Objective:To investigate the postoperative effect of paranasal concavity augment by block united with diced autologous costal cartilage.Methods:The data of 76 patients who were underwent costal cartilage rhinoplasty together with paranasal augmentation from January 2016 to December 2019 were analyzed retrospectively. The surgical technique was described in detail. Medical charts and operative records were reviewed to summary the complications. Patients′subjective satisfaction of the postoperative nasal appearance was self-evaluated with grading (1 worse, 2 no change, 3 improved, and 4 much improved). Cosmetic effects were evaluated by the measurements of the nasolabial angle and the distance between ACJ and intertragic notch preoperatively and postoperatively.Results:The postoperative follow-up duration was 6 to 34 months. Overall, functional and aesthetic outcome was satisfactory in most patients, and the mean score by the patients′self-evaluation was 3.4±0.5. Graft exposure, mobility, or significant resorption, pneumothorax or significant donor-site pain were not observed. The average nasolabial angle was changed from (78.2±13.2)° preoperatively to (89.8±10.2)° 6 months postoperative at the last follow-up ( t=152.00, P<0.01). And the distance from the alar-cheek junction to the left tragus was increased by 3.8±2.1 (2.2-6.1) mm. Conclusions:Costal cartilage rhinoplasty combined with augmentation of parasal area can improve parasal depression, with stable postoperative effect and fewer postoperative complications, and has a good effect for patients with normal occlusal relationship or mild abnormality.

The postoperative complications, glabellar fullness, inverted brow triangle, nasal polygon aesthetic shape and patient satisfaction were evaluated. These data were measured and analyzed, including the nasal length, nasal tip height, nasal frontal angle and nasal facial angle before and after the operation.Results:In 86 patients, the incision healed in one stage after surgery, and 8 cases had nasal vestibular scar hyperplasia. All patients were followed up for 1-5 years: 84 cases obtained satisfactory nasal morphology, and 2 cases recovered naturally after adjusting and lowering the prosthesis height half a year after surgery because the interbrow area was too full. 74 patients (86%) were very satisfied, 10 cases (11.6%) were satisfied. The nasal length was (4.07±0.20) cm, the nasal tip height was (2.66±0.36) cm, the nasal frontal angle was (106.42±8.04)°, and the nasal face angle was (15.90±0.85)°before operation. The nasal length was (4.23±0.20) cm, the nasal tip height was (2.59±0.26) cm, the naso-frontal angle was (113.69±6.34)°, and the naso-facial angle was (21.57±0.78)° at eighteen months after operation. There were statistically significant differences in nasal length, naso-frontal angle and naso-facial angle ( t=-5.51, -5.96, -52.31, P<0.01), but no statistically significant differences in nasal tip height ( t=1.47, P=0.146). Conclusions:The ship-shaped e-PTFE can be shaped to reflect the aesthetic of the nose dorsum, which is similar to the anatomical structure of the nose dorsum, increase the stability and authenticity of the prosthesis, and is worthy of clinical application.
摘要
Objective:To investigate the clinical effect and application value of free skin or auricle composite tissue transplantation in the correction of nasal alar retraction.Methods:From August 2019 to January 2023, a total of 45 patients with nasal retraction (7 males and 38 females) were treated in Shanghai United Regal Medical Cosmetology Hospital. Age ranged from 18 to 46 years, with a mean of 26.6 years. All patients had retroalar margin retraction caused by insufficient alar lining to varying degrees, with a retraction distance between 2-5 mm, with an average retraction distance of 3.3 mm. 11 cases of nasal flange retraction were corrected by free transplantation of composite tissue of auricle directly. The remaining 34 patients were corrected by alar border cartilage graft and free skin graft.Results:During 2-18 months of follow-up, 41 patients had satisfactory results and no obvious complications. Partial necrosis of free skin was observed in 2 patients, ischemic necrosis of complex flap of auricle was observed in 1 patient, and necrosis of free skin was observed in 1 patient. In addition to the above complications, 3 patients reported that the correction of alar retraction did not achieve the expected effect, but indicated that they were satisfied with the surgical effect, which was considered to be caused by skin contracture and other factors. The overall satisfaction rate of all patients was 91.1%. After follow-up and statistics, 41 patients in this group were satisfied with the results, with an overall satisfaction rate of 91.12%.Conclusions:The application of free skin graft (or auricle composite tissue) to correct nasal alar retraction has the advantages of simple operation, wide indications and accurate efficacy, and is worthy of clinical promotion.
