Tumor de Pott y absceso cerebral secundario a sinusitis aguda de foco dentario en paciente pediátrico / Pott's tumor and cerebral abscess secondary to acute sinusitis of dental focus in a pediatric patient

El tumor de Pott es una entidad rara, definida como un absceso subperióstico asociado a osteomielitis del hueso frontal. Suele presentarse como complicación de sinusitis aguda o crónica del seno frontal, y se describe con mayor incidencia en población pediátrica, siendo una complicación grave por su alta morbimortalidad. Se presenta a un paciente pediátrico con tumor de Pott y absceso cerebral posterior a una sinusitis aguda de foco odontogénico, en la que los pilares de tratamiento son drenaje quirúrgico precoz y antibioticoterapia prolongada. Se describe la clínica, manejo médico-quirúrgico y seguimiento posterior, ya que, en ausencia de antecedentes, se debe buscar dirigida- mente enfermedad periodontal y realizar un estudio de inmunodeficiencia primaria.

Pott's tumor is a rare entity, defined as a subperiosteal abscess associated with osteomyelitis of the frontal bone. It usually presents as a complication of acute or chronic sinusitis of the frontal sinus and it is described with a higher incidence in the pediatric population, being a serious complication due to its high morbidity and mortality. We present a pediatric patient with Pott's tumor and brain abscess after acute sinusitis of odontogenic focus, in which the pillars of treatment are an early surgical drainage and prolonged antibiotic therapy. The clinic, medical-surgical management and subsequent follow-up are described, since in the absence of antecedents, periodontal disease should be sought directly and a study of primary immunodeficiency performed.

Celulitis orbitaria secundaria a sinusitis. Presentación de un caso / Orbital cellulitis secondary to sinusitis. Case presentation

La celulitis orbitaria es la causa más frecuente de inflamación aguda de la órbita y constituye una urgencia oftalmológica relativamente frecuente y potencialmente grave en la población pediátrica. La inflamación puede extenderse a la región postseptal, y afectar el contenido de la órbita. La relación anatómica de la órbita con estructuras vecinas como los senos paranasales, es clave para entender la etiopatogenia de la enfermedad; aparece, en la mayoría de las ocasiones, como complicación de una sinusitis. Se presenta una paciente de cinco años de edad, con diagnóstico de celulitis orbitaria secundaria a una sinusitis. La descripción de las características clínicas de la enfermedad y su manejo en este caso, puede aportar información útil para el mejor abordaje de la entidad. Se concluye que los elementos fundamentales son el diagnóstico temprano y la atención multidisciplinaria.

Orbital cellulitis is the most frequent cause of acute swelling of the orbit and is a relatively frequent ophthalmological emergency and potentially serious in the pediatric population. The inflammation may extend to post septal region, and affect the orbit content. The anatomical relation of the orbit with their neighboring structures as paranasal sinuses is the key to understand the etiopathogenesis of the disease; a case of a five-year-old patient is presented, with a diagnosis of orbital cellulitis secondary to sinusitis. The description of the clinical characteristics of the disease and its management in this case, may offer useful information for a better approach of this entity. It is concluded that the main elements are early diagnosis and multidisciplinary evaluation.

A Case of Periorbital Necrotizing Fasciitis Occurred in Patient with Fungal Sinusitis / 대한이비인후과학회지

Orbital complications due to sinusitis usually occur in children and spread from the ethmoid or frontal sinusitis. Periorbital necrotizing fasciitis, which is an aggressive infection characterized by extensive necrosis and gas formation in the fascia and subcutaneous tissue, is uncommon as an orbital complication due to sinusitis. Because most of orbital complications of the fungal sinusitis occur from invasive fungal infection in immunocompromised patients, orbital complications due to non-invasive maxillary fungal ball in healthy patients are extremely rare, especially if the complication is periorbital necrotizing fasciitis. We report a case of periorbital necrotizing fasciitis that occurred in a healthy 44-year-old male patient with non-invasive fungal sinusitis, which was treated with a combination of intravenous antibiotics and endoscopic sinus surgery and ophthalmologic surgical treatment.

Approach to Frontal Sinus Outflow Tract Injury

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications. This paper aimed to examine the surrounding anatomy, diagnosis, and treatment of FSOT.

Role of balloon sinuplasty in the treatment of frontal sinusitis

A fifty-one-year-old male was diagnosed with recurrent frontal sinusitis; the patient completed the full course of optimal medical therapy: nasal steroids, antibiotics and nasal douches. The patient's symptoms did not improve including frontal headaches, nasal congestion and facial tenderness over the frontal sinus. CT scan of the sinuses was performed, and it confirmed the diagnosis of isolated right frontal sinusitis. The patient underwent "balloon sinus dilatation under local anesthesia" in the ENT outpatient clinic, and he was followed-up for 18 months to monitor any complication or symptom. This was the first case that had balloon sinuplasty procedure in Bahrain under local anesthesia in a clinic setting

Resección del tabique intersinusal frontal para el manejo de sinusitis frontal crónica unilateral / Frontal Intersinus Septum Takedown (FISST) as management of chronic unilateral frontal sinusitis

La sinusitis frontal crónica es un problema complejo, de difícil manejo quirúrgico debido a la anatomía del seno frontal y el alto índice de recidiva posquirúrgica. La resección del tabique intersinusal ha sido descrita escasamente en la literatura, pero es una técnica sencilla que aprovecha el drenaje del seno contralateral sano, evitando intervenir directamente el ostium comprometido, en especial en casos de estenosis u obliteración que probablemente se reproducirán después de permeabilizarlos mediante otras técnicas. En este artículo describimos un caso clínico, la técnica quirúrgica utilizada y sus resultados en una paciente con múltiples cirugías de senos paranasales previas, tanto por vía endoscópica como abiertas, con buen resultado posoperatorio. Además realizamos una revisión de la literatura pertinente.

Chronic frontal sinusitis is a complex issue and its surgical management is difficult due to the anatomy of the frontal sinus and the high rate of recurrence after surgery. Resection of the intersinus septum has been scarcely described in the literature, but is a simple technique that takes advantage of the drainage of the healthy contralateral sinus, avoiding the direct intervention of the compromised ostium, especially in cases of stenosis or obliteration that would probably reproduce after permeabilization by other techniques. In this article we present a case report, the surgical technique that was chosen and the results in a patient with multiple previous sinus surgeries, both open and endoscopic, with a good postoperative outcome. Also, we provide a review of the relevant literature.

Frontoethmoidal Cells on Computed Tomographic Analysis: The Prevalence and Relationship to Frontal Sinus/Recess Mucosal Thickening

OBJECTIVES: To determine the prevalence of frontoethmoidal cells (FECs) in patients with and without frontal sinus/recess mucosal thickening and to establish the relationship between the FECs and the frontal sinus/recess mucosal thickening. MATERIALS AND METHODS: We retrospectively reviewed 245 consecutive ostiomeatal CT scans (490 sides). The normal and frontal sinus/recess mucosal thickening groups were categorized based on these images. The latter group was sub-categorized into the frontal sinus mucosal thickening group (FS group) and the frontal recess mucosal thickening group (FR group). RESULTS: Types 1, 2, 3 and 4 frontal cells were found in 17.5, 6.7, 8.3 and 0% of 326 normal sides, respectively. The prevalence of agger nasi, suprabullar, frontal bullar, supraorbital ethmoid and interfrontal sinus septal cells was 85.6, 43.3, 4.9, 4.3 and 17.2% of the same 326 normal sides, respectively. Type 3 frontal cells, frontal bullar cells and suprabullar cells were more prevalent in the FS and FR groups than in the normal group. All types of cells were more prevalent in the FS group, but only the suprabullar cells were more prevalent in the FR group than in the normal group. CONCLUSION: These findings suggest that type 3 frontal cells, frontal bullar cells and suprabullar cells may have a significant association with frontal sinus/recess mucosal thickening.

A Case of Subdural Empyema Caused by Sinusitis in a Child / 소아감염

The current paper reports on a case of subdural empyema secondary to frontal sinusitis in an otherwise healthy child. Sinusitis is a common and benign condition in most pediatric cases. Because of the widespread use of antibiotics, intracranial extension of pediatric sinusitis is rarely seen today; however, complications (e.g., cavernous sinus thrombosis, orbital infection, meningitis, and subdural empyema) are potentially life threatening. A 15-year-old right-handed male presented with a 3-day history of fever, headache, and left-sided palsy. Computed tomography revealed right-sided subdural empyema with right frontal sinusitis and maxillary sinusitis. A postoperative inpatient neurological consultation was requested 2 months post-surgery due to motor function deficits. The results suggested that early and accurate diagnosis of subdural empyema leads to prompt treatment and a favorable outcome for the patient.

Celulitis orbitaria, celulitis frontal y empiema como complicaciones de sinusitis / Orbital cellulitis, frontal cellulitis and empyema as sinusitis complications

La celulitis orbitaria usualmente ocurre como complicación de infecciones de los senos para nasales, y la etiología es principalmente bacteriana. Para realizar un diagnóstico e implantar terapéutica temprana tiene gran importancia reconocer las manifestaciones clínicas de la sinusitis y las edades más afectadas, pues dada su ubicación anatómica, pueden complicarse también con infecciones del sistema nervioso central, que en la edad pediátrica tienen una connotación especial. Se presentan aquí dos pacientes de 10 y 14 años de edad respectivamente, que desarrollaron celulitis orbitaria en un caso, y celulitis frontal y empiema en el otro; así mismo, se muestran los medios diagnósticos utilizados para identificar signos tempranos de posibles complicaciones, con el objetivo que el pediatra pueda identificarlos, así como la terapéutica implantada para dar solución o evitar estas complicaciones

Orbital cellulite generally occurs as a complication of paranasal sinus infections and the etiology is mainly bacterial. It is very important to recognize the clinical manifestations of sinusitis and the most affected ages to make a correct diagnosis and to apply early treatment, since its anatomical location may bring complications with central nervous system infections which, at pediatric ages, can acquire special significance. Here are two patients aged 10 and 14 years, who developed orbital cellulitis in one case and frontal cellulitis and empyema in the other. Likewise, the diagnostic means used to identify the early signs of possible complications were presented, in order that a pediatrician can detect them, as well as the treatment to solve or to prevent these complications

Evoluiu com remissão da doença. CONSIDERAÇÕES FINAIS: A falência no diagnóstico e no tratamento das complicações da rinossinusite pode levar a sequelas e complicações fatais.O diagnóstico de osteomielite frontal é firmado pela suspeita clinica e confirmado por exames radiológicos.A cirurgia está indicada quando a evolução for insidiosa, havendo sequestro ósseo ou complicações intracranianas.

INTRODUCTION: The frontal osteomyelitis is a complication of rhinosinusitis which can evolve to acute or chronicle. There is inflammatory reaction by the increasing of intraosseous pressure, ischemia and local necrosis, leading to bone abscess formation. There is no drainage, it will occur detachment of the periosteum, soft tissue invasion and worsening of ischemia with subsequent bone sequestration. METHOD: Case report of an inpatient in an emergency service of another institution by the complication of rhinosinusitis who was referred to the Otorhinolaryngology Service of University Hospital Professor Edgard Santos of Federal University of Bahia. CASE REPORT: Male patient, 16 years-old, presented himself to the ER of another institution with cephalea, vomits and fever which evolved to periorbital edema and frontal to the left, moving to palpebral fluctuation and frontal. Subjected to frontal and palpebral abscess drainage, with broad-spectrum antibiotic therapy with no improvement. He was referred to our service keeping edema and fluctuation in region frontal and light edema in left periorbital region. The nasal endoscopy showed edema in meatus to the left and the computerized tomography showed fronto-ethmoid sinusitis to the left and signs of frontal osteomyelitis with bone sequestration and epidural empyema. Subjected to sinasal endoscopy surgery, external Access or removal of the frontal one affected and epidural empyema drainage. Evolved to the remission of the disease. FINAL CONSIDERATIONS: Failure in the diagnosis and rhinosinusitis complication treatment can lead to sequalae and fatal complications.

Anatomy, classification of intersinus septal cell and its clinical significance in frontal sinus endoscopic surgery in Chinese subjects / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Intersinus septal cell (ISSC) is not a very uncommon frontal recess cell. But it is poorly described in literature. The clinical significance of this anatomic variant still remains unclear. The purpose of this study was to clarify the anatomy, classification of ISSC and its clinical significance in Chinese subjects.</p><p><b>METHODS</b>We prospectively identified ISSC in 200 consecutive subjects who had undergone computed tomography (CT) scans: 120 without frontal sinusitis (group 1) and 80 with frontal sinusitis (group 2). The ISSC was classified into two types: Type I ISSC communicated with frontal sinuses, type II ISSC communicated with frontal recess. The patients of frontal sinusitis had undergone functional endoscopic sinus surgery with the assistance of the classification of ISSC. Statistical analysis was performed to correlate the ISSC and its type to the presence of frontal sinusitis.</p><p><b>RESULTS</b>The ISSC was obvious when reviewing the coronal and axial CT scans. Of the 200 CT scans reviewed, ISSC were present in 90 (45%). Of the 120 scans in group 1, ISSC were present in 49 (41%), among which type I ISSC was in 22 (18%) and type II was in 27 (23%). Of the 80 scans in group 2, ISSC was present in 41 (51%), among which type I ISSC was in 16 (20%) and type II was in 25 (31%). There were no statistically significant differences about the frequency distribution of total ISSC, type I and II ISSC between group 1 and group 2.</p><p><b>CONCLUSIONS</b>The prevalence of ISSC was very high in Chinese patients. The classification of ISSC was helpful for surgeon to operate according to whether it communicated with frontal sinus or frontal recess. The type II ISSC could be relatively easily removed from frontal recess.</p>

Analysis of follow-up outcomes of endoscopic modified Lothrop procedure / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To sum up the follow-up outcomes of endoscopic modified Lothrop procedure (EMLP) and retrospectively analyze the indications, methods and prognostic factors of EMLP.</p><p><b>METHODS</b>The collected data of 73 cases who received EMLP with frontal sinus diseases were analyzed in this paper. The mean age was 45.6 (ranging from 14 to 72 years). There were 52 males and 21 females. Only patients with follow-up time greater or equal to 6 months were included. Paranasal sinus CT scan was adopted for all cases and MRI for tumor patients. All patients were followed under endoscope.</p><p><b>RESULTS</b>There were 21 inverted papilloma in the frontal sinus, 16 chronic sinusitis with asthma, 12 frontal sinusitis, 9 chronic sinusitis with or without polyps, 7 osteoma of the frontal sinus, 4 frontal mucocele, 3 allergic fungal sinusitis and 1 congenital encephalocele. Sixty-one cases had prior surgical history (1.8 times on the average). Their mean follow-up was 25.0 months, (ranging from 6 to 122 months). At the end of follow-up, 44 cases (60.3%) had well opened frontal drainage pathway. Twenty-five (34.2%) was re-stenosed and 4 (5.5%) closed. Seven cases (9.6%) underwent revision surgeries. There were no surgical complications.</p><p><b>CONCLUSIONS</b>EMLP is an effective and salvage procedure in dealing with tumor of frontal sinus and recurrent frontal sinusitis. Combined with medical treatment, EMLP will have a better results for chronic sinusitis with or without polyps and asthma. The degree of diseases, mucosal loss, anatomic variability and prior surgeries are important prognostic factors.</p>

Effects of Frontal Recess Cells on the Development of Frontal Sinusitis / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Frontal recess anatomy can be very complex, with accessory cells extending to the frontal sinus and possibly contributing to the obstruction of the frontal sinus. However, there is still controversy on the effect of the frontal recess cells. We designed this study to assess the effect of frontal recess cells on frontal sinusitis. SUBJECTS AND METHOD: We retrospectively reviewed chart and collected data of those who visited the outpatient clinic between January and June, 2011. Parnasal sinus CT was taken with Brillance 64-slice computed tomography scanners. The image was reviewed by two or more otolaryngologists to identify the frontal recess cells. The nasofrontal isthmus diameter and the area of nasofrontal isthmus was reconstructed and measured with workstation. Then, we compared the radiological results of frontal recess cells with the frequency of frontal sinusitis. RESULTS: The presence of anterior group of frontal recess cells showed no influence on the frontal recess anatomy. The presence of frontal bullar cell was significantly associated with the development of frontal sinusitis by simple (p=0.001) and multiple (p=0.038) logistic regression models. It was shown that the narrower the area of frontal isthmus the more developed were the frontal sinusitis, showing statistically significance in the simple (p=0.013) and multiple (p=0.017) logistic regression models. CONCLUSION: Our results also showed that similar results compared to previous Asianreport. The narrowness of nasofrontal isthmus could be the cause of frontal sinusitis. The frontal bullar cell could be the cause of frontal sinusitis encroaching on the frontal recess and affect the nasofrontal pathway.

Endoscopic Endonasal Treatment of a Pott's Puffy Tumor

Pott's puffy tumor is an infrequent entity characterized by a subperiosteal abscess associated with frontal bone osteomyelitis. It has become rare due to the development of antibiotics and is usually seen as a complication of frontal sinusitis. Although Pott's puffy tumor is more commonly described in children, it should also be included in the differential diagnosis of swelling on the forehead in adults. Once the diagnosis is suspected, appropriate imaging should be performed to evaluate the possible complications. The treatment of Pott's puffy tumor combines medical and surgical approaches in order to prevent further complications. The goal of surgery is to drain the sinus and to excise the infected bone if necessary. The endoscopic endonasal approach is a safe and effective alternative to the external approach. This report describes the case of a 25-year-old man with Pott's puffy tumor resulting from frontal sinusitis.
