Abstract
OBJECTIVE: Sinusitis or rhinosinusitis is a very common disease worldwide, and in some cases, it leads to intracranial complications (ICS). These are more common in immunocompromised patients or with underlying comorbidities, but even healthy individuals, can be affected. Nowadays, ICS have become less common thanks to improved antibiotic therapies, radiological diagnostic methods, surgical techniques and skills. Nonetheless, they can still cause significant morbidity and mortality. For this reason, management of these complications requires a multidisciplinary approach to plan and customize treatment options. This paper presents our strategy in the management of a series of intracranial complications induced by acute sinusitis and compares our experience and outcomes with the literature. STUDY DESIGN: Single institute experience, retrospective analysis of cases series and literature review. METHODS: Adult and child patients who were treated for ICS in the Department of Otorhinolaryngology at Sion Hospital, in Switzerland from 2016 to 2020 were included. Their symptoms, medical history, clinical and radiological findings, treatment, and outcome were documented. RESULTS: Eight patients (6 males- 2 females) aged from 14 to 88 y.o., were enrolled. None had any previous history of chronic, or recurrent sinusitis. Moreover, very few presented specific rhinological symptoms, but with neurological or other symptoms. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) were used to confirm the diagnosis of all ICS. All types of known intracranial complications were observed in our cohort with a wide range of extension and severity of sinusitis. A multidisciplinary approach with individual treatments was tailored to each patient. Outcomes were favorable in almost all patients with neither recurrence, nor neurological sequels being observed in the follow-up. Only one patient was lost due to fatal complications of advanced lung cancer. CONCLUSION: ICS remain a challenging clinical problem due to substantial associated morbidity and mortality. The incidence of these complications is relatively low. Therapeutical management guidelines are lacking. Early detection and multidisciplinary approach are key to successful treatment.
