RESUMO

Objective To investigate the expression of PIK3CA,phosphorylated protein kinase B(p-AKT)and phosphatase and tensin homologue deleted on chromosome 10(PTEN)in sinonasal squamous cell carcinoma(SNSCC).Methods The expressions of PIK3CA and PTEN in head and neck squamous cell carci-noma(HNSCC)were analyzed through the data set of HNSCC in the cancer genome map of UCSC Xena data-base.The immunohistochemical SP method was used to measure the expression of PIK3CA,p-AKT and PTEN in 43 cases of SNSCC tissues,20 cases of normal inferior concha tissues.The relationship between the expressions of PIK3CA,p-AKT and PTEN protein with the clinicopathological features and prognosis of the patients with SNSCC was analyzed.Results The results of bioinformatic analysis showed that PIK3CA mR-NA expression in HNSCC tissues was higher than that in paracancerous tissues(P<0.01),while the PTEN mRNA expression was lower than that in paracancerous tissues(P<0.05).The immunohistochemical detec-tion results showed that the positive expressions rates of PIK3CA and p-AKT proteins in normal nasal mucosa tissues were significantly lower than those in SNSCC tissues,while the positive expression rate of PTEN pro-tein in SNSCC tissues was significantly higher than that in normal inferior nasal concha mucosa tissues,and the differences were statistically significant(P<0.01).The expressions of PIK3CA and p-AKT protein were related to the clinical stage,differentiation degree and primary site(P<0.05),but were not related to age,gender,smoking and drinking(P>0.05);the PTEN protein expression was not related with the clinical stage,differentiation degree,primary site,age,smoking and drinking(P>0.05).The Spearman analysis showed that the expression of PIK3CA in SNSCC tissues was positively correlated with p-AKT protein ex-pression(r=0.664,P<0.01),and PIK3CA was negatively correlated with PTEN protein(r=-0.414,P<0.01).The expression of p-AKT was negatively correlated with PTEN protein(r=-0.453,P<0.01).The Kaplan-Meier analysis showed that the median survival time of the patients with PIK3CA and p-AKT protein positive expression was shorter than that of the patients with negative expression(P<0.01).There was no statistically significant difference in median survival between the patients with PTEN protein positive expres-sion and those with negative expression.Conclusion The overexpressions of PIK3CA and p-AKT accompa-nied by the loss of PTEN expression participate in the development and progression of SNSCC,moreover the PIK3CA and p-AKT expressions are related to the poor prognosis of the patients.

RESUMO

Abstract Introduction Angioleiomyoma is a rare neoplasm that represents ∼ 0.2 % of all head and neck benign tumors and ∼ 2% of total cases of tumors of the sinonasal tract. It was once considered a possible subtype of leiomyoma, but, in the 2020 World Health Organization (WHO) classification of soft tissue tumors, it is accepted as a singular entity. Objective To systematically review the existing literature on angioleiomyoma in the light of the new classification of soft tissue tumors. Data Synthesis The present study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A comprehensive search in the PubMed, Cochrane, Scopus, and Google Scholar databases was performed in January 2022. The search items included the following keywords: nasal angioleiomyoma OR sinonasal angioleiomyoma OR nasal vascular leiomyoma OR sinonasal vascular leiomyoma. A total of 87 patients were evaluated. He age of the patients in the studies ranged from 15 to 88 years (mean age at diagnosis: 55.6 years). The most common site of involvement was the nasal septum (28.4 %), followed by the inferior turbinate (22.5%). The most common symptom was nasal obstruction (66.7%), followed by epistaxis (47.1%). Surgical excision represented the main treatment, and there was recurrence of pathology in only 1 case (0.9%). Conclusion To our knowledge, only 87 cases of sinonasal-tract angioleiomyoma have been previously described. The results of the present review seem to confirm the rarity and the benign nature of this neoplasm, and they seem to confirm the necessity to improve the available data about sinonasal-tract angioleiomyoma.

RESUMO

Biphenotypic sinonasal sarcoma (BSNS) is a recently described, low-grade, slow-growing sarcoma with neural and myogenic features with exclusive location in sinonasal track and characteristic PAX3- MAML3 gene fusion. Differentiating this tumor from its commoner mimics needs knowledge of this entity to avoid over treatment. This tumor has unique morphology, clinical course, and genetics. We report this in a 47-year-old female who was diagnosed with such a rare, solitary fibrous tumor—hemangiopericytoma (HPC-SFT) on limited initial biopsy. On subsequent excision, typical morphology and immunohistochemistry helped to clinch the diagnosis.

RESUMO

Abstract Introduction Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and positive sinonasal bacterial cultures may be recalcitrant to topical therapy alone due to the additional local inflammatory burden associated with bacterial infection/colonization. Objectives To evaluate sinonasal outcomes in CRSwNP patients with a positive perioperative bacterial culture, who were treated with postoperative intranasal corticosteroids (INCS) alone versus INCS in combination with a short-term course of oral corticosteroids (OCS). Methods This is a retrospective chart review of CRSwNP patients. A total of 59 patients met inclusion criteria, including positive perioperative bacterial culture and treatment with INCS with or without concomitant use of OCS. Two cohorts were formed based on the chosen postoperative medical treatment; 32 patients underwent postoperative INCS alone, while 27 underwent INCS plus a ≤ 2-week course of OCS. The 22-item sinonasal outcome test (SNOT-22) scores and Lund-Kennedy scores (LKS) were assessed preoperatively, and at 2-week, 4-week, and 4 to 6 months after endoscopic sinus surgery (ESS). Results There were no statistically significant differences in postoperative sinonasal symptoms or endoscopic scores between the cohorts treated with INCS plus OCS versus those prescribed INCS alone (p > 0.05). Our regression model failed to demonstrate a relationship between the use of OCS and better sinonasal outcomes at 2-week, 4-week, and 4 to 6 months after ESS (p > 0.05). Conclusions Our study suggests that in a cohort of CRSwNP patients with recent bacterial infections, the postoperative use of combined OCS and INCS did not result in a statistical improvement of endoscopic and symptomatic outcomes over INCS irrigation alone. However, both treatment groups had a clinically significant improvement based on the Minimal Clinically Important Difference.

RESUMO

SMARCB1 deficient sinonasal carcinomas are rare neoplasms, classified under sinonasal undifferentiated carcinomas by the fourth edition of the World Health Organization (WHO) classification of head and neck tumors. It is characterized immunohistochemically by loss of SMARCB1(INI1) expression. We are reporting the case of a 63-year-old man who was evaluated for nasal stuffiness of 3 months duration in another hospital where a radiological evaluation showed a polypoidal soft tissue lesion in the right maxillary sinus extending to the right nasal cavity and spheno-ethmoidal sinus. He underwent excision biopsy which was reported as non- keratinizing nasopharyngeal carcinoma. He was referred to our center with residual disease in spheno-ethmoidal recess for which radiotherapy was given. After completion of radiotherapy, the primary site had no residual disease, but while on follow-up he developed left sided neck nodes within 4 months of completion of treatment. Excision of the lesion was done and histopathological and immunohistochemical analysis revealed it to be metastasis from SMARCB1 deficient sinonasal carcinoma and not nasopharyngeal carcinoma as diagnosed from the other center. This case is being reported to highlight the diagnostic challenge associated with this rare entity.

RESUMO

We describe the case of a 72-year-old female diabetic who presented with epiphora and purulent discharge from the right eye for the past 2 years and multiple skin lesions over the right upper eyelid and right arm for 1 year. Computed tomography of the paranasal sinuses revealed mucosal thickening in the frontal and ethmoidal sinuses, with a polypoidal mass from the right side of the nasal septum and dacrocystitis. The histopathology of the skin lesion was suggestive of lupus vulgaris (LV). There was no evidence of pulmonary tuberculosis. This case was a rare coexistence of LV with sinonasal tuberculosis and dacrocystitis.

RESUMO

Sinonasal inverted papilloma(SNIP) is a kind of benign tumor originating from the nasal cavity and paranasal sinuses, accounting for 70% of papillomas. The incidence of the disease is more common in males, with an average age of 50-60 years. It is most likely to occur in unilateral maxillary sinus and ethmoid sinus, followed by sphenoid sinus and frontal sinus.It has the characteristics of local invasion, high recurrence rate and malignant tendency, and most malignant transformation into squamous cell carcinoma. Endoscopic nasal resection and appropriate adjuvant therapy can help to reduce the recurrence rate and inhibit further deterioration. We report the results of a 10-year follow-up of a SNIP patient, including the clinical manifestations, recurrence course and treatment plan during the 10 years. The patient underwent multiple nasal endoscopic surgeries, and had a recurrence of multiple focal attachment pattern, and finally had direct invasion and distant metastasis. Tumor recurrence and further deterioration persisted despite the use of a comprehensive treatment.

RESUMO

Abstract Objective To generalise the features of PANP in case of potential clinical and pathological pitfall of diagnosis. Methods Thirteen patients diagnosed as PANP were retrospectively analyzed in the Pathology Department of Capital Medical University from August 2014 to December 2019. Immunohistochemical staining with CD34, CK, Vim, Calponin, Ki67, Bcl-2, and STAT-6 was performed with envision-two steps method. Results PANP is a benign tumor presenting with gross variegated tan to gray soft fleshy tissue with foci of obvious hemorrhage and necrosis. The imaging shows internal heterogeneous hyperintensity with a peripheral hypointense rim while postcontrast images display a strong nodular and patchy enhancement. Vimentin (Vim) stain was consistently positive, while negative for CD34, STAT-6 and Bcl-2 (focal positive in two cases). Calponin and CK stain was positive in nine cases, respectively. Conclusion PANP is a clinically rare tumor which may simulate malignancy lesion. Recognizing of characteristic features in these thirteen patients would be beneficial to avoid misdiagnosis and unnecessary aggressive treatment. Level of evidence: This work was Level 2 of evidence according to the Guide for Authors.

RESUMO

Aim: The aim of our study is to analyze the staining models for VEGF, p16, and p53, as well as to understand the biology of inverted papilloma caused by smoking. Materials and Methods: Thirty-one cases, diagnosed with sinonasal inverted papilloma between 2015 and 2019, were included. Demographic data such as age and gender, admission symptoms of the patients, and anatomical location, stage, surgical technique, and recurrence information were obtained from clinical follow-up files. Immunohistochemical staining for p16, VEGF, and p53 were performed on patient materials. Results: In our study, the female to male ratio was 9.33 with an average age of 53.137 ± 13.96 years. Of the patients, 17 were nonsmokers and 14 were smokers. No significant relationship was found between smoking status and relapse and dysplasia. In contrast, a significant relationship between the Krouse stage and dysplasia (P = 0.005) was observed. A similar significant relationship was observed between p16 immunohistochemical expression and dysplasia (P = 0.030). On the other hand, VEGF and p53 immunohistochemical expressions were not significantly related with dysplasia and recurrence. Conclusions: Inverted papillomas are benign tumors that clinically give symptoms similar to nasal polyps. However, recurrence and malignant transformation potential exist and the factors causing this risk are not clearly identified. In our study, no malignant transformation was observed in patients who were admitted to our hospital.

RESUMO

Resumen Durante la cirugía endoscópica nasosinusal, la sección inadvertida y retracción hacia la órbita de la arteria etmoidal anterior (AEA) es el mecanismo habitual del hematoma orbitario (HO); éste se manifiesta con proptosis, dolor y déficit visual potencialmente irreversible. El déficit visual es secundario a isquemia del nervio óptico por aumento de la presión intraocular, siendo suficientes treinta minutos para que ocurra daño visual permanente. Por sus secuelas el tratamiento del HO debe ser rápido y agresivo. Presentamos el caso de un varón de 72 años con diagnóstico de rinosinusitis crónica con pólipos nasales refractaria a tratamiento médico que se sometió a cirugía endoscópica nasal y que desarrolló en el posoperatorio inmediato con un HO. Se manejó precozmente con cantotomía-cantolisis, descompresión orbitaria medial endoscópica y control vascular de la AEA. El paciente evoluciona favorablemente, sin déficit visual. En este artículo se discutirán el diagnóstico y manejo oportunos del hematoma orbitario iatrogénico.


Abstract During endoscopic sinonasal surgery, inadvertent section of the anterior ethmoidal artery (AEA) with retraction into the orbit is the usual mechanism of orbital hematoma (OH), leading to proptosis, pain, and potentially irreversible visual loss. Thirty minutes is sufficient for retinal ischemia and permanent visual loss. The explanation for blindness is due to increased intraorbital pressure. The treatment of iatrogenic HO must be quick and aggressive, because if it is not managed in time, it can cause a permanent visual deficit. We present the case of a 72-year-old man with a diagnosis of chronic rhinosinusitis with nasal polyps refractory to medical treatment who underwent nasal endoscopic surgery, evolving in the immediate postoperative period with an HO, requiring canthotomy - cantolysis and early surgical reintervention for endoscopic medial orbital decompression and vascular control of AEA. The patient evolves favorably, without visual deficit. This article will discuss the timely diagnosis and management of iatrogenic orbital hematoma.

RESUMO

Background:There is a sudden rise of fungal infection with coronavirus disease. This is attributed to the immunomodulation by the disease and the drugs used, diabetes mellitus, steroid use, oxygen inhalation using dirty water, use of zinc and iron supplements, etc. Early diagnosis and prompt medical and surgical intervention is the mainstay of treatment. This can greatly reduce the high morbidity and mortality associated with this disease. The objective of the retrospective study is to describe the imaging findings of acute invasive rhino-orbito-cerebral mucormycosis (ROCM) in 58 patients with severe acute respiratory syndrome coronavirus 2, from SVP hospital with proven mucormycosis. Special emphasis is placed on the signal patterns of sinonasal mucosa, the earliest and most common findings.Material And Methods:We report the sinonasal, orbital and neuroimaging findings in patients of suspected acute invasive ROCM. A total of 58 patient’s scans were analyzed. The study comprises cases performed at two different imaging modalities and a tertiary care hospital from March 23,2021 to September 1, 2021. All the patients had positive reverse transcriptase polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2 and were hospitalized with clinically severe disease as per the guideline s laid down during the second wave in India. They were on intravenous steroids and oxygen. Thirty patients (52%) had diabetes mellitus. All of them presented with headache, facialand/or orbital pain,periorbital puffiness with decreased vision, during the course of treatment. CT or MRI examination of the paranasal sinuses, orbits and brain was done, with intravenous contrast wherever possible. The presence of mucormycosis was confirmed by histological diagnosis in all of them following clinico-radiological diagnosis of acute invasive ROCM. Result:Computed tomography (CT) and magnetic resonance imaging (MRI) of 58 patients showed most commonly involved sinuse s as maxillary and ethmoid sinuses together. Sino-nasal mucosal thickening was the most common finding. Periantral infiltration preceded orbital, cerebral complications, with grossly intact bones. Sinus wall erosions were seen in only patients and maxillary alveolar arch erosionwere frequent findings. CT showed hypodense soft tissue thickening or fat stranding as the predominant finding in involved areas, while MRI showed T2 iso-to hyperintense mucosal thickening with T2 hypointense component as the main finding. Conclusion:MRI is better at demonstrating early mucosal abnormalities, turbinate necrosis, devitalized tissues, orbital apex involvement and intra-cerebral extension. Imaging findings of inflammatory tissue infiltration adjacent to the paranasal sinuses in premaxillary, retroantral fat, facial muscles, pterygopalatine fossa, temporal, infratemporal fossa and extraconal orbital-fat along with typical patterns of sinonasal mucosal thickening should raise the suspicion of acute invasive fungal etiology given the short duration of history and immunocompromised status. High incidence of periantral and orbital extension of the disease is suggestive of acute invasive form of fungal infection. Also the rapidly progressive inflammatory changes without much bone involvement should suggest the suspicion of ROCM. Bony, cerebral and vascular involvements are relatively late complications.

RESUMO

Objective@#To present our surgical experience and technique in performing endoscopic sinus surgery for vascular sinonasal tumors without pre-operative embolization using intraoperative ligation of the external carotid artery or its distal branches.@*Methods@#Design: Retrospective Series. Setting: Tertiary Private Teaching Hospital. Participants: Seven Patients. @*Results@#Out of 7 patients (5 males, 2 females, aged 12 to 64 years old) with non-embolized vascular sinonasal tumors, 2 had juvenile angiofibroma, 3 had a benign vascular tumor (hemangiopericytoma, hemangioma and a vasoformative solitary fibrous tumor), and 2 had a malignancy (rhabdomyosarcoma, squamous cell carcinoma). Four (57.1%) had external carotid artery ligation, two (28.6%) had internal maxillary artery ligation and one (14.2%) had sphenopalatine artery ligation. The mean intraoperative blood loss was 2447.1 mL (range 900mL to 5,000mL) and average operation duration was 7.6 hours (range 2.9 hours to 14.5 hours). The average amount of transfused blood products was 1785.7mL (zero to 3,000mL). The average hospital stay was 7 days (range 2 to 13 days) with one post-operative complication (ICU admission for hypotension from intraoperative blood loss). @*Conclusion@#Intraoperative ligation of the ECA or its distal branches to disrupt the vascular supply of sinonasal tumors may provide a viable means of preventing excessive intraoperative blood loss in patients with non-embolized vascular sinonasal tumors.

RESUMO

Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

RESUMO

Due to the paranasal sinuses adjacent to the orbit, the sinonasal malignancy is prone to invade the orbit, which is not only the advanced stage of the tumor, but also one of the poor prognostic factors. Preoperative CT and MRI scan and intraoperative frozen section analysis are used to evaluate the orbital invasion of the tumor. Orbital preservation is adopted if the periorbita is not transgressed by tumor. Orbital preservation can be considered if the tumor invades the periorbita and extraconal fat in a limited range, responds well to neoadjuvant chemotherapy, radiotherapy or other multimodality treatment, or has a negative section margin. Orbital exenteration is performed if the tumor extensively invades the periorbita, and invades the extraocular muscle, eyeball and orbital apex. Whether orbital preservation or orbital exenteration is adopted, it should be evaluated and made decision by a multidisciplinary team, and fully communicate with the patient.

RESUMO

Abstract Introduction Anatomical variations in the sinonasal region are remarkably common and these variations may have an impact on maxillary sinus development due to their close anatomical adjacency. Objective The aim of this study was to investigate the effect of anatomical variations of the sinonasal region on the width, height, length, and volume of the maxillary sinus. Methods Cone beam computed tomography records of 120 patients were evaluated. Nasal septum deviation angle was measured for each patient and patients were divided into three groups as mild, moderate, and severe. Sinonasal variations such as nasal septum deviation direction, septal spur, concha bullosa, uncinate process pneumatization, middle concha hypertrophy, inferior concha hypertrophy, paradoxical middle concha and presence of septa in the maxillary sinus were registered. Cone beam computed tomography images were transferred to the SimPlant software thus right and left maxillary sinus volumes and dimensions were measured separately. Results There was a negative and statistically significant relationship between age and left maxillary sinus width (p= 0.015). The relationships between gender and maxillary sinus volumes and dimensions were statistically significant (p< 0.05). Although there were significant relationships between the nasal septum deviation severity, middle concha hypertrophy, inferior concha hypertrophy, paradoxical middle concha, and presence of septa and maxillary sinus dimensions; there was no significant relationship between septal spur, nasal septum deviation direction, concha bullosa, uncinate process pneumatization, and maxillary sinus dimensions. No statistically significant relationship could be determined between maxillary sinus volume and anatomical variations of the sinonasal region. Conclusion According to our findings, while certain the variations were found to affect the sinus dimensions; none of the variations was found to be related to the maxillary sinus volume.


Resumo Introdução As variações anatômicas na região nasossinusal são extremamente comuns e essas variações podem ter um impacto no desenvolvimento do seio maxilar, devido à proximidade anatômica. Objetivo Investigar o efeito das variações anatômicas da região nasossinusal na largura, altura, comprimento e volume do seio maxilar. Método Foram avaliados registros de tomografia computadorizada de feixe cônico de 120 pacientes. O ângulo de desvio do septo nasal foi medido para cada paciente e os pacientes foram divididos em três grupos: leve, moderado e grave. Foram observadas variações nasossinusais, como direção do desvio do septo nasal, esporão septal, concha bolhosa, pneumatização do processo uncinado, hipertrofia da concha média, hipertrofia da concha inferior, concha média paradoxal e presença de septos no seio maxilar. Imagens de tomografia computadorizada de feixe cônico foram transferidas para o software SimPlant e, portanto, os volumes e dimensões dos seios maxilares direito e esquerdo foram medidos separadamente. Resultados Houve uma relação negativa e estatisticamente significante entre a idade e a largura do seio maxilar esquerdo (p = 0,015). As relações entre gênero e volumes e dimensões do seio maxilar foram estatisticamente significantes (p < 0,05). Embora houvesse relações significativas entre a gravidade do desvio do septo nasal, hipertrofia da concha média, hipertrofia da concha inferior, concha média paradoxal e presença de septos e dimensões do seio maxilar, não houve relação significativa entre esporão septal, direção do desvio do septo nasal, concha bolhosa, pneumatização do processo uncinado e dimensões do seio maxilar. Nenhuma relação estatisticamente significante pôde ser determinada entre o volume do seio maxilar e as variações anatômicas da região nasossinusal. Conclusão De acordo com nossos achados, embora certas variações tenham afetado as dimensões sinusais, nenhuma das variações foi efetivamente relacionada ao volume do seio maxilar.

RESUMO

Los queratoquistes maxilares son frecuentes en pacientes con síndrome de Gorlin. Su tratamiento es debatido por su alta tendencia a la recidiva. En los últimos años la cirugía endoscópica nasosinusal ha adquirido importancia en el manejo de esta patología. Exponemos en caso de un varón de 16 años afecto de este síndrome con queratoquistes maxilares donde se realiza un abordaje combinado, endonasal y transoral.


Maxillary keratocysts are frequent in Gorlin Syndrome patients. Its treatment is discussed due to the high tendency to recurrence. In the last years the sinonasal endoscopic surgery has become an important tool in the management of this pathology. We report a 16 years old boy with Gorlin Syndrome and maxillary keratocysts treated with a trans-nasal endoscopic and intra-oral combined approach.
