RESUMEN
Chronic otitis with cholesteatoma is a potentially dangerous disease that can lead to the development of intracranial abscesses. Although cerebellar abscess is half as common as cerebral abscess, it is known for its particularly difficult diagnosis, which requires the visualization of the pathological process continuity from the mastoid to the posterior fossa. In this article, we present an extremely rare case from the literature of cholesteatomatous otomastoiditis complicated with meningitis and cerebellar abscess, along with the description of technical surgical details for the plugging of the bony defect between the mastoid and posterior fossa with muscle and surgical glue. The particularity of this case lies in the late presentation to the doctor of an immunocompetent patient, through a dramatic symptomatology of life-threatening complications. We emphasize the importance of responsibly treating any episode of middle ear infection and considering the existence of underlying pathologies. In such cases, we recommend additional neuroimaging explorations, which can prevent potentially lethal complications. The treatment of such intracranial complications must be carried out promptly and requires collaboration between a neurosurgeon and an ENT surgeon.
RESUMEN
Background and objectives: Knowledge of the interactions and influences of infectious, genetic, and environmental factors on the evolution and treatment response of malignant tumors is essential for improving the management of the disease and increasing patient survival. The objective of this study was to establish the contribution of human papillomavirus (HPV), as well as p53 and p16 tumor markers, alongside associated factors (smoking and alcohol consumption), in the progression of malignancies located in the oropharynx and at the retromolar trigone-oropharyngeal junction. Materials and Methods: We performed a prospective study including 50 patients with malignant tumors of the oropharynx and retromolar trigone-oropharyngeal junction. In all patients, the presence and type of HPV were determined, as well as the status of the tumor markers p53 and p16. The associated risk factors, biopsy results, treatment method, and post-treatment evolution were all documented. Statistical analyses were performed to evaluate the correlations between the determining factors and their influence on the post-treatment evolution. An overall increased survival rate was found in HPV(+) patients. Results: Our study outlined the prevalence of different high-risk subtypes of HPV from the ones presented by other studies, suggesting a possible geographic variation. Correlations between the p53 and p16 statuses and patient survival could be established. The association of smoking and alcohol consumption strongly correlated with an unfavorable evolution. Conclusions: Awareness of the differences in the post-treatment evolution of the patients in relation to the presence of the factors determined in our study could change the future management of such cases for ensuring improved treatment outcomes.

INTRODUCTION: One of the aspects that have an influence on rhinosinusal endoscopic surgery is extrasinusal pneumatization, which can also affect less common structures at this level. The pneumatization of the superior and supreme turbinates, uncinate process and crista galli are perfect examples of this situation. The diagnosis is made only through imaging methods. MATERIALS AND METHODS: This is a retrospective anatomo-radiological study analyzing 205 CT scans of the facial sinuses performed over a three years period. All patients were symptomatic and the CT scans were performed to assess the cases prior to surgery. Ninety-seven patients were females and 108 males, aged between 18 and 91 years. RESULTS: The prevalence of pneumatization and the prevalence of the different pneumatization types (superior and supreme turbinate, uncinate process and crista galli) were determined. CONCLUSIONS: The pneumatization of the supreme turbinate (10.24%) was less common than that of the superior turbinate (29.76%) and affected all its anatomical variations (A, B, C). Pneumatization of the crista galli process was recorded in 22.92% of the cases, especially in association with type 2, while the prevalence of pneumatized uncinate process was of only 3.41% (uni- or bilateral).
