          Abstract

          SUMMARY: Introduction: Acute frontal rhinosinusitis is defined as an acute infection of the frontal sinus. Spreading of this infection to surrounding structures is uncommon but, when present, carries significant morbidity and mortality. Description: In this case report, we present two unusual cases of frontal rhinosinusitis complications. Firstly, we describe a case of acute rhinosinusitis with orbital complications caused by a frontoethmoidal osteoma. In the second case, the infection extended to the underlying bone and through the skull causing osteomyelitis and focal meningitis complicated with an abscess. After appropriate treatment, both patients were free of infection at follow-up, without complications. Discussion: In the first case we presented, a frontoethmoidal osteoma gave rise to rhinosinusitis with orbital complications. These benign tumors rarely cause symptoms, but when large enough, sinus outflow can be blocked, making the osteoma clinically relevant. Osteomas can induce frontal rhinosinusitis, giving rise, among other conditions, to the development of orbital complications like periorbital cellulitis or the formation of a periorbital abscess. Diagnosis of osteoma is usually straightforward on computed tomography and surgical treatment is only indicated for large tumors, rapid growth, intracranial or orbitary extension. In the second clinical case, the infection extended to the underlying bone and through the skull causing osteomyelitis and focal meningitis with abscess formation. In this patient, a Draf Type IIa procedure was performed for the frontal abscess drainage, followed by proper antibiotic and anti-inflammatory therapy. Conclusions: Complications of frontal rhinosinusitis are uncommon but require immediate attention and aggressive treatment to avoid morbidity and mortality. In these cases, our patients were properly treated with good outcomes, avoiding potentially more dangerous complications.

          RESUMEN: Introducción: La rinosinusitis frontal aguda se define como una infección aguda del seno frontal. La propagación de esta infección a las estructuras circundantes es poco común, pero, cuando está presente, conlleva una morbilidad y mortalidad significativas. Descripción: En este reporte presentamos dos casos inusuales de complicaciones de rinosinusitis frontal. En primer lugar, describimos un caso de rinosinusitis aguda con complicaciones orbitarias por osteoma frontoetmoidal. En el segundo caso, la infección se extendió al hueso subyacente y a través del cráneo causando osteomielitis y meningitis focal complicada con un absceso. Tras el tratamiento adecuado, ambos pacientes quedaron libres de infección en el seguimiento, sin complicaciones. Discusión: En el primer caso que presentamos, un osteoma frontoetmoidal dio lugar a una rinosinusitis con complicaciones orbitarias. Estos tumores benignos rara vez causan síntomas, pero cuando son lo suficientemente grandes, el flujo de salida del seno puede bloquearse, lo que hace que el osteoma sea clínicamente relevante. De hecho, los osteomas pueden inducir una rinosinusitis frontal, dando lugar, entre otras condiciones, al desarrollo de complicaciones orbitarias como celulitis periorbitaria o formación de un absceso periorbitario. El diagnóstico de osteoma suele ser sencillo mediante tomografía computarizada y el tratamiento quirúrgico solo está indicado para tumores grandes, de crecimiento rápido, con extensión intracraneal u orbitaria. En el segundo caso clínico, la infección se extendió al hueso subyacente y a través del cráneo provocando osteomielitis y meningitis focal con formación de abscesos. En este paciente, se realizó un procedimiento Draf Tipo IIa para el drenaje del absceso frontal, seguido de una adecuada terapia antibiótica y antiinflamatoria. Conclusiones: Las complicaciones de la rinosinusitis frontal son poco frecuentes, pero requieren atención inmediata y un tratamiento agresivo para evitar la morbilidad y la mortalidad. En estos casos, nuestros pacientes fueron tratados adecuadamente con buenos resultados, evitando complicaciones potencialmente más peligrosas.

          Intracranial complications of frontal sinusitis in children: Pott's puffy tumor revisited.

          The objective of the present study is to describe the diagnosis and treatment of intracranial complications of frontal sinusitis (Pott's puffy tumor) in a series of pediatric patients at our institution. A rare entity, Pott's puffy tumor has been reported in only 21 pediatric cases in the literature of the antibiotic era. The hospital records and radiographic files at Rainbow Babies and Childrens Hospital, Cleveland, Ohio, USA, over the previous 16 years were retrospectively reviewed in a search for patients with the diagnosis of Pott's puffy tumor, defined as scalp swelling and associated intracranial infection. There were 6 male patients and 1 female patient. Ages ranged from 11 to 18 years (median 14.5 years). Intracranial infections consisted of epidural abscess in 5 patients, subdural empyema in 4 and brain abscess in 1. Intraoperative cultures grew anaerobic organisms in 1 patient, microaerophilic streptococcus in 5 patients, Klebsiella species in 1 patient and Streptococcus pneumoniae in another. All patients presented with frontal scalp swelling, and other common symptoms included headache, fever, nasal drainage and frontal sinus tenderness. Five patients were treated with antibiotics prior to their presentation. Four patients presented with neurologic decompensation characterized by varying degrees of hemiparesis, obtundation, pupillary dilatation or aphasia. All patients underwent craniotomy and evacuation of the intracranial infection. Even severely impaired patients demonstrated full neurologic recovery. Despite the widespread use of antibiotics, neurosurgical complications of sinusitis continue to occur. A high degree of suspicion, along with prompt neurosurgical intervention and the use of appropriate antibiotics, can result in favorable outcomes in even the sickest patients.

            Intracranial complications of acute frontal sinusitis.

            Despite advances in the diagnosis and treatment of acute frontal sinusitis, there is still significant occurrence of intracranial complications. Urgent surgical evacuation of any intracranial collection is required; however, the surgical management of the associated sinusitis remains controversial. Ten patients presented to this department over a 12-month period with subdural empyema secondary to acute frontal sinusitis. Four patients had a coexisting Pott's puffy tumour and one patient had a periorbital abscess. Each patient was managed using a multidisciplinary approach. A frontal sinus trephine/drain +/- antral washout was performed at the same time as craniotomy with evacuation of the empyema. With this approach only two patients suffered long-term morbidity in our series, in the form of persistent neurological or cognitive deficit. No patient required a definitive sinus procedure. This study emphasizes the need for the early assessment and intervention of patients with an intracranial complication secondary to acute frontal sinusitis. Further assessment of the underlying sinus disease is indicated during outpatient follow up after the acute episode.

              Surgical decisions in the management of frontal sinus osteomas.

              The development of chronic rhinosinusitis, a mucocele, or persistent headaches is a common indication for the removal of a frontal sinus osteoma. The best surgical approach to ensure complete and safe removal of the lesion is less clearcut. The advent of specialized frontal sinus instruments, angled endoscopes, and surgical navigational systems has made removal of frontal sinus osteomas possible through an endoscopic approach. The aim of this study is to review our recent experience with the surgical management of frontal sinus osteomas, and the anatomic features that make specific lesions more or less amenable to endoscopic resection. A retrospective review of all frontal sinus osteomas surgically resected from the years 1999 to 2003 was used. This period was selected to reflect the invention and popularization of surgical navigation systems and specialty instruments designed specifically for the frontal sinus. CT scans, operative reports and postoperative course were reviewed. Nine patients were identified. A grading system was devised to reflect the three variables involved in the limitations for endoscopic removal. These are the location of the base of attachment, relative size to the frontal recess, and location in relation to a virtual sagittal plane through the lamina papyracea. Three osteomas were removed through an endoscopic approach. Four were removed by a combined osteoplastic flap and endoscopic dissection of the frontal recess. Two were removed through an osteoplastic flap with obliteration of the sinus. The ability to remove a frontal sinus osteoma endoscopically can be determined preoperatively, taking into account the location and size of the lesion. There is still a role for external procedures in the surgical management of these lesions, and such procedures may be combined with endoscopic techniques for optimal results.
