RESUMO

Objective:The aim of this study is to evaluate the efficacy of endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma. Method:Forty-three patients with olfactory neuroblastoma undergoing surgery combined with radiotherapy were retrospectively analyzed. The patients were divided into endoscopic surgery and conventional surgery. All patients received postoperative radiotherapy at a dose of 60-70 Gy, the 5-year survival rate and local recurrence time of the two groups were compared, and the therapeutic effects of endoscopic surgery and traditional surgery were compared. Result:Through survival analysis, the 5-year overall survival rates of the traditional surgery group and the endoscopic surgery group were 50% and 58% (P=0.560), the local recurrence rates were 44% and 48% (P=0.288), and the mean recurrence time was 5.6 months and 12.5 months (P=0.032). Conclusion:There was no difference between endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma, and the time of local recurrence was significantly prolonged. In early Neuroblastoma, endoscopic sinus surgery may be superior to open surgery in terms of efficacy and patient survival.

RESUMO

PURPOSE: The aim of this study was to determine the valuable magnetic resonance imaging (MRI) features of sinonasal metastatic clear-cell renal cell carcinoma (cc-RCC), especially focusing on its dynamic-enhanced characteristics. METHODS: The conventional and dynamic-enhanced MRI findings of 8 patients with histopathologically confirmed sinonasal metastatic cc-RCC were reviewed by 2 radiologists. The control group of 8 patients with capillary hemangioma underwent the same MRI protocol. RESULTS: Metastatic cc-RCCs arose from the nasoethmoid region, maxillary sinus, posterior ethmoid and sphenoid sinus, and nasal cavity in 2 patients in each. These lesions were well circumscribed and the mean maximum dimension was 42 mm. The signal intensity of these lesions was isointense to brain stem on both MR T1- and T2-weighted images. All metastatic tumors showed vivid enhancement on enhanced T1-weighted image. Multiple flow voids within these metastatic lesions were identified in 6 patients. Peripheral cyst was detected around the metastatic tumor in 4 patients. Metastatic cc-RCCs exhibited a characteristic type 4 time intensity curve (TIC) similar to that of the internal carotid artery, whereas capillary hemangiomas showed a type 3 TIC on dynamic-enhanced MRI. CONCLUSIONS: A hypervascular mass with the characteristic type 4 TIC in the sinonasal region is highly suggestive of a metastatic cc-RCC.

RESUMO

Parapharyngeal infections carry a significant risk of extensive suppuration and airway compromise. We report the case of a patient presenting with a right paranasopharyngeal abscess, featuring atypical symptoms that made diagnosis particularly challenging. Complications included evidence of right vocal cord paralysis, likely secondary to involvement of the vagus nerve. Notably, this paralysis occurred in isolation, without involvement of cranial nerves IX or XI, which would be expected from jugular foramen encroachment. Imaging demonstrated the presence of a collection extending towards the skull base, which was drained using a transnasal endoscopic approach, avoiding the use of external incisions. Tissue biopsies from the abscess wall suggest that the underlying aetiology was minor salivary gland sialadenitis, which has not been previously reported in the literature.

RESUMO

INTRODUCTION: acoustic rhinometry (AR) is a non-invasive method measuring the nasal volume (NV) and the nasal minimal cross-sectional area (MCA), reflecting nasal obstruction. The first objective of this study was to measure and compare NV and MCA between 3 groups of children: "achondroplasia", "Down syndrome" and "control". The control group corresponded to children with suspicion of sleep disorder disease and without cranio-facial malformation. The second objective was to correlate AR measurements with the obstructive apnea-hypopnea index (OAHI). METHODS: prospective study between February and July 2017, in a tertiary care center. The following data were collected: demographic characteristics, medical and surgical history, NV, MCA, and OAHI. RESULTS: 83 children were included. The mean NV was lower in achondroplasia group compared to control group: 2.75 cm3 vs 3.60 cm3 (p = 0.02, 95% CI [0.0694, 0.7456]). Negative correlation was found between the NV and the OAHI for children with achondroplasia (T = -0.37; p = 0.02). CONCLUSIONS: AR is an effective tool for assessing nasal obstruction in children. Nasal obstruction was correlated to OAHI in achondroplasia. AR could become a routine tool in the management of nasal obstruction of children with cranio-facial malformations.

RESUMO

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare lesion in nasal cavity first reported by Wenig and Heffner in 1995. Most commonly seen in men in third to ninth decade of life. Majority of cases presents as a polypoidal mass in one or both nasal cavities. We experienced such a case of REAH originating from the nasal septum, in posterior aspect, treated by endoscopic approach. It is important to differentiate REAH from other sinonasal pathologies like inverted papilloma and low grade sinonasal adenocarcinoma. Complete surgical resection is the treatment of choice.

RESUMO

RATIONALE: Neurologic deficits are rare in patients with extranodal natural killer/T-cell lymphoma (NKTL), nasal type. We present a case that was initially suspected as tuberculous meningitis, but later diagnosed as central nervous system metastasis of NKTL, nasal type, which has never been published previously. PATIENT CONCERNS: A 55-year-old Chinese man presented with persistent headache and fever. The initial head computed tomography and magnetic resonance imaging (MRI) scan was normal. Low glucose, elevated protein, and pleocytosis of cerebral spinal fluid led to a diagnosis of tuberculous meningitis. The patient did not respond to anti-tuberculosis treatment, and his symptoms aggravated. MRI showed abnormal lesions in the right hemisphere and a lesion in the maxillary sinus region. DIAGNOSIS: Endoscopic biopsy of the maxillary lesion showed features consistent with NKTL. Positron emission tomography revealed a hypermetabolic mass involving the right maxillary sinus and brain. INTERVENTIONS: The patient received chemotherapy. OUTCOMES: The patient died 30 days after chemotherapy. LESSONS: Lymphoma of the nasal cavity and paranasal sinuses is extremely rare and may be easily misdiagnosed. Nasal NKTL metastasis should be considered when a patient presents with symptoms of leptomeningeal involvement.

RESUMO

We present a rare and unusual case of a 16-year-old girl, with no significant medical history, presenting with right nasal obstruction and suspected sinusitis with occasional epistaxis and haemoptysis. On examination, she had a mass lesion in the right nasal cavity, with no evidence of other pathology on assessment of the ears, nose, throat or head and neck. A CT scan revealed an opacified right maxillary sinus with polypoidal mucosa, extending and passing through the accessory ostium into the right nasal cavity. Examination under anaesthesia with functional endoscopic sinus surgery and excision of the lesion was subsequently undertaken. Histological analysis confirmed the mass lesion as a haemangioma. This case report is the first to present a maxillary haemangioma presenting as nasal obstruction with intermittent sinusitis symptoms in a child. The authors discuss the incidence, presentation and management of maxillary haemangiomas in the paediatric population.

RESUMO

Summary A 44-year-old woman with left nasal obstruction and facial numbness for 4 months was admitted to hospital. The patient did not have amblyopia, vision loss, runny nose with blood, dizziness ,headache or other discomfort.In 1991 and 2001, the patient were pathologically diagnosed as pleomorphic adenomas.CT of nasal cavity and paranasal sinuses showed that in the left maxillary sinus there was an about 4.4 cm×4.5 cm×4.7 cm large mass soft tissue density, showing expansive growth protruding into the left orbital floor.MRI showed that the lumped short T1 signal was seen in the left maxillary sinus and the linear long T1 signal was seen in the left nasal cavity, and the liquid accumulation signal foci could be seen in the left maxillary sinus.Postoperative pathological findings: (left maxillary sinus mass) Combining morphology, immunohistochemical results and medical history, consistent with pleomorphic adenoma carcinogenesis (cancer in pleomorphic adenoma), carcinogenesis type is myoepithelial carcinoma.

RESUMO

SummaryRenal clear cell carcinoma(RCCC) is the most common type of renal cell carcinoma, but metastasis to the nasal cavity is extremely rare. A case of RCCC to the nasal cavity and paranasal sinuses was reported. The early clinical manifestations of this case were intermittent epistaxis and subsequent massive epistaxis. Imaging examination revealed that there were masses in the nasal cavity and paranasal sinus, accompanied by bleeding and destruction of the skull base. Renal CT examination showed a tumor in the right kidney, and considered the patient suffering from renal cell carcinoma. The patient underwent a nasal side incision to remove the tumor, the patient's pathological return; nasal nephrogenic clear-cell carcinoma.

RESUMO

An 11-year-old, 5.8-kg, male European cat was presented with a 4-month history of sneezing, nasal discharge, respiratory distress and bilateral conjunctivitis. Physical examination showed bilateral hemorrhagic mucopurulent nasal discharge and stertorous respiratory sounds. An irregular shaped mass involving the aboral portion of the right nasal cavity and sphenoidal sinus was identified by computed tomography. The mass was localized endoscopically in the medium meatus and an endoscopic-guided biopsy was performed. B-cell lymphoma was diagnosed by histopathological and immunochemistry exams. Functional endoscopic sinus surgery allowed to completely remove the tumor and restore a normal nasal flow. The cat showed no recurrence of the neoplasia for 15 months after the functional endoscopic sinus surgery.

RESUMO

OBJECTIVE: Prompted by a recurring skull base multidisciplinary team debate on the necessity of securing a definitive tissue diagnosis before initiating treatment for lesions of the orbital apex, a review of anterior skull base procedures over an 11-year period was undertaken. METHODS: Data collected prospectively on cases from 2006 to 2017 were analysed. Presenting symptoms, imaging and histology findings, outcomes, complications, and impact on treatment were evaluated. All surgery was carried out endoscopically with the aid of image guidance. RESULTS: Twenty-one patients undergoing endoscopic orbital apex and/or optic canal biopsy were included. The mean patient age was 49 years. Five malignant tumours were identified, five benign tumours, seven infective cases (two tuberculosis and five fungal) and two cases of immunoglobulin G4 related disease. Two patients had non-diagnostic biopsies (one lesional) and were treated successfully as Tolosa-Hunt syndrome cases. CONCLUSION: A successful diagnosis was achieved in nearly all cases without adverse impact, other than one cerebrospinal fluid leakage case. Management was directly influenced by the outcome in all cases.

RESUMO

BACKGROUND: Central giant cell granuloma (CGCG) is a rare, non-neoplastic, benign lesion that exhibits expansive and osteolytic biological behavior. CGCG treatment and management is challenging for clinicians. CASE PRESENTATION: This report presents the treatment and management of recurrent, aggressive CGCG after surgical resection. After informed consent was obtained, the patient underwent radiotherapy. The lesion size was reduced significantly, with no evidence of recurrence or malignant transformation. CONCLUSIONS: This treatment experience indicates that radiotherapy can be used as a rescue treatment for complicated CGCG involving vital neurovascular structures of the cranial base.

RESUMO

Objective:Esthesioneuroblastoma(ENB) is a sinonasal rare tumor, and the assessment on the prognosis have not been used with on consensus, our study aims to set an accuracy indicator to predict the outcomes of ENB.Method:A retrospective review was performed on 31 ENB patients. We collected 31 patients with ENB and reviewed the clinical data and pathological slides; modified Kadish stages were evaluated by otolaryngologist and imaging specialist; Hyams grading system were confirmed by two pathologists, who reviewed and paid attention to the pathological characteristics of Hyams grading system. Finally, the relation among the clinical data, pathological features and clinical outcome of these 31 ENB were analyzed by Kaplan-Meier method.Result: The Hyams grading system and modified Kadish stage were considered together seemed to evaluate the prognosis of ENB more accurately, when the scores over 6 points, the patients had the poor prognosis with the mean median survival months of 24.67±32.22, compared with the scores under 6 and the final scores reached at 4, 5, 6, 7, 8, the tumor metastasis rates were 14.3%, 16.7%, 33.3%, 50.0%, 100.0% respectively.Conclusion:Taking the Hyams grading system and modified Kadish stage into consideration, which may evaluate the prognosis of ENB more accurately.

RESUMO

OBJECTIVES: Inflammatory myofibroblastic tumor (IMT) is a rare benign lesion, especially in the pediatric age. There are several cases described in pulmonary, digestive and renal localizations, but involvement in head and neck area is infrequent. METHODS: Case report and review of the literature. RESULTS: A 1 year and 11 months old child, during 2 months had clinical signs of nasal respiratory insufficiency and epistaxis subsequently developing a purulent rhinorrhea and a sleep apnea. His pediatrician previously requested a sinus and cavum X-ray with the finding of an image compatible with an intranasal mass. Endoscopic resection was performed of the mass with further immunohistochemical analysis showing the result of a lesion compatible with IMT. CONCLUSIONS: Even though there are very few cases in scientific literature of a tumor with these characteristics in infants, IMT must be present as a differential diagnosis of intranasal masses. The role of the pathologist is essential to reach the definitive diagnosis and the performance of an early surgical treatment decreases aesthetic consequences in this pathology.

RESUMO

INTRODUCTION: Benign fibrous histiocytoma (BFH) is a mesenchymal tumor composed of fibroblasts and histiocytes, which normally occurs in the bone tissue and/or the skin of the limbs. BFH of the nasal septum is rare worldwide. PATIENT CONCERNS: A 38-year-old female patient attended our clinic with congestion in her right nasal cavity. DIAGNOSES: Endoscopic examination revealed a mass within the right nasal passage. Immunohistochemical staining demonstrated cells labeled with VIM (+), CD68PGM1 (+), CD34 (-), Actin (-), PCK (-), EMA (-), Desmin (-), SMA (-), S-100 (-), P63 (-), ALK-1 (-), beta-catenia (+), and KI67 (+). Clinical and histopathological examinations showed that the mass was a septum-originated BFH. INTERVENTIONS: For the treatment of BFH of the nasal septum, the mass was removed endoscopically using a transnasal approach. OUTCOMES: No recurrence was observed over 30 months of follow-up. CONCLUSION: To prevent the recurrence wide local resection with histological clear margin and long-term follow-up with an endoscope are necessary.

RESUMO

A 52-year-old male who had chronic hypertension for several years presented with abrupt epistaxis. The CT scan revealed a 40 mm × 40 mm mass in the nasal cavity intended to the maxillary sinus and the base of skull. Nasal endoscope biopsy and serum/urinary catecholamine detection conformed an ectopic noradrenaline-secreting pheochromocytoma. The present research was to discuss the clinical characteristics of the rare pheochromocytoma and the palliative interventional embolization for it.

RESUMO

OBJECTIVE: To determine the frequency distribution of bleeding sites in idiopathic hidden arterial epistaxis. METHODS: In this retrospective cohort study, 107 patients with hidden arterial epistaxis were endoscopically examined for sites of bleeding. RESULTS: All sites of hidden arterial epistaxis were identified by endoscopic examination. Bleeding sites were identified at initial surgery in 103 patients and during the second surgery in 4. The bleeding sites included: the olfactory cleft region in 47 patients, the inferior meatus region in 29, the middle meatus region in 11, multiple bleeding sites (olfactory cleft and anterior septum) in 3, the anterior roof of the nasal cavity in 4, the nasal floor in 11 and the nasopharynx in 2. The bleeding points showed a white or red volcano-like bump in 75 patients, isolated prominent telangiectasia in 21 and mucosal ulceration in 11. CONCLUSION: Common sites of hidden arterial epistaxis include the olfactory cleft, inferior meatus and middle meatus. However, there should be awareness of some uncommon bleeding sites (including the anterior roof of the nasal cavity, the nasal floor and the nasopharynx) and of multiple bleeding sites.

RESUMO

OBJECTIVE: To discuss the reasons for misdiagnosis of supernumerary nasal teeth. METHODS: Clinical data of four supernumerary nasal tooth patients were analysed retrospectively at visits to our otolaryngology department between 2005 and 2018. RESULTS: All four patients were male and had a supernumerary nasal tooth in the right nasal cavity. Three of the four patients had previously been misdiagnosed. All the supernumerary nasal teeth were surrounded by granulation tissue or hypertrophic nasal mucosa, and were subsequently confirmed by computed tomography and endoscopy. The granulation tissue or hypertrophic nasal mucosa was removed using microwave ablation, and the supernumerary nasal teeth successfully removed by endoscopy. CONCLUSION: Supernumerary nasal teeth are rare, and are usually misdiagnosed because such teeth are surrounded by hypertrophic nasal mucosa or granulation tissue. They can be confirmed by computed tomography and endoscopy.

RESUMO

BACKGROUND: The nasal cavity (NC) is the entrance to the respiratory system. Many studies have been conducted on the structure, function and volume of the NC. Only a few studies were performed assessing the volumetric values of NC and conchae. OBJECTIVES: The aim of this study was to evaluate the volumetric measurements of the NC, conchae and nasal septum using the stereological method. MATERIAL AND METHODS: Cone-beam computed tomography (CBCT) images of 200 individuals (100 females and 100 males) aged 8-59 years were retrospectively evaluated. Inferior nasal concha and middle nasal concha, NC and nasal septum volumes were measured on these images. Measurements were made using point counting method, which is based on the Cavalieri principle. The mean values of the measured structures for 2 age groups and for each gender were obtained. Differences between the groups and genders of all parameters were examined. The volume fractions of measured volumes were calculated. RESULTS: The mean volumes of the nasal septum, left and right NC, left and right inferior nasal conchae, and left and right middle nasal conchae were 4.99 ±1.51 cm³, 7.44 ±2.93 cm³, 7.68 ±2.99 cm³, 3.10 ±1.11 cm³, 3.04 ±1.02 cm³, 1.32 ±0.56 cm³, and 1.28 ±0.49 cm³, respectively. Gender and age differences were statistically significant in all volumes (p < 0.05). CONCLUSIONS: The data obtained in this study may assist clinicians in planning treatment, assessing the treatment results of pathological conditions within the NC, and help surgeons in preoperational and postoperational evaluations, especially in dentistry, otorhinolaryngology and plastic surgery.
