However, they have an important morbidity and mortality rate, and can be a source of disabling neurological sequelae in the absence of a rapid diagnosis and adequate treatment. We carry a retrospective study of 23 patients having sinusitis with intracranial complications, treated between 1996 and 2011. All patients underwent complete ENT and neurological examination, biological investigations and sinonasal and cerebral CT. An intraveinous large-spectrum antibiotherapy was administered to all patients. Twenty patients underwent surgery. It included evacuation of the intracranial collection, sinus drainage, with or without cranialization of the frontal sinus. Evolution was assessed on clinical biological and radiological criteria. Mean age was 25 years and sex-ratio was 3.6. Neurological signs were the most frequent symptoms. Rhinological signs were essentially purulent rhinorrhea (14 cases) and nasal obstruction (12 cases). Nasal endoscopy showed pus in the middle meatus in 10 cases. On CT, intracranial complications included subdural empyema (11 cases), extradural empyema (7 cases) and brain abscess (5 cases). Associated cerebral thrombophlebitis was noted in 4 cases. Three patients with extradural empyema had had an exclusive medical treatment. All other patients (20 cases) were operated. Clinical and radiological evolution was favorable after initial treatment in 14 cases (60.8%). Six patients required secondary surgery. Two patients have died despite intensive care. The intracranial complications of sinusitis are serious and source of important morbidity and mortality. Management should rapid and adequate, combining effective antibiotic therapy and eventually neurosurgical treatment.展开更多

The purpose of this study was to evaluate the reliability of computed tomography (CT) in the positive diagnosis of otosclerosis, to compare the radiological findings to those intraoperatively, and to seek a correlation between imaging data and postoperative audiometric results. This is a retrospective study of 60 patients having otosclerosis, treated in our department between 2009 and 2011. All patients underwent an otoscopic examination, pure tone and vocal audiometry, impedancemetry and petrous CT scan. At petrous CT scan, a footplate thickening was found in 9 cases. Labyrinthine bone hypodensity was noted in 51 cases. Sensitivity of CT in the diagnosis of otosclerosis was 100%. Regarding the operative findings and their correlation with imaging, we found that among the 7 facial canal procidences reported intraoperatively, CT had identified 6, with a sensitivity of 86%. Of the 53 facial nerve in normal position intraoperatively, CT had only identified 34, with a specificity of 64%. Regarding the ossicles, there were 6 cases of abnormalities of the incus, among them 3 were identified on CT, with a sensitivity of 50%. The 54 patients with normal ossicular chain intraoperatively were all identified as such on CT, with a specificity of 100% (p = 0.001). For correlation between imaging and postoperative results, it was found that patients with extended otosclerosis had lower postoperative audiometric improvement than those having localized disease (p < 0.05). Computed tomography is necessary for the diagnosis of otosclerosis. It also helps, with good sensitivity and specificity, seeking for anatomical variants that the surgeon could possibly encounter during surgical procedure. Finally, there is a statistically significant correlation between imaging data and postoperative audiometric results, allowing establishing a functional prognosis even before surgery.展开更多

Fewer than 100 cases have been reported in the literature. Case presentation: A 52-year-old man, presented with a two-month history of dysphonia. Nasofibroscopy showed left submucosal bulging of the laryngeal supraglottic floor. Cervical computed tomography showed extensive left supraglottic mass, with partial lysis of the thyroid cartilage. Direct laryngoscopy showed left submucosal bulging of the supraglottic floor. Transmucosal biopsies were performed. Histological study concluded to the presence of a diffuse large-cell B lymphoma. The patient was treated with chemotherapy followed by external radiotherapy. Evolution was favourable. Conclusion: Although primary laryngeal non-hodgkin lymphoma is rare, it should be considered in the differential diagnosis of a mass in the neck region, especially in the supraglottic area. Direct laryngoscopy with biopsy makes the diagnosis. Treatment and prognosis depend on the stage and the grade of the lymphoma.展开更多

It’s rarely revelatory of the clinical feature and corresponds to a mass with partly cystic and partly solid areas. A 65-year-old man, followed up for hypertension, complained of a progressive swelling in the left paranasal part of the face lasting for 3 months. Physical examination revealed a left paranasal swelling of 4 cm diameter, with a healthy looking skin. CT facial bones found a round formation of 2 cm involving the left maxilla. He received tumor resection by vestibular pathway. Histological examination showed many giant cells. We then discussed the brown tumor diagnosis. The PTH dosage was high: 645 pg/mL (normal: 15 - 68 pg/mL). The serum calcium was in the superior normal limit (100 mg/dL). Cervical ultrasound revealed a bottom left parathyroid nodule. A lower left parathyroidectomy was performed. Histological results confirmed parathyroid adenoma. Monitoring was marked by a marked decrease of the PTH serum level then a return to normal values, a normocalcemia and no recurrence of the maxillary tumor with Recoil of 14 months. Brown tumor of the maxilla is rare and should be considered even in absence of hypercalcemia.展开更多
