RESUMO
Objective:Anatomical variation or scar atresia of the drainage channel of the frontal sinus on the affected side, and opening the frontal sinus through the drainage channel of the frontal sinus on the affected side may lead to surgical failure. The purpose of this study is to explore a modified Draf â ¢ operation to complete the drainage of the affected frontal sinus by removing the floor wall and septum of the frontal sinus and connecting the bilateral frontal sinus through the healthy side of the frontal sinus. Methods:Through the anatomical study of 2 skull bone specimens and 2 fresh frozen specimens, the surgical landmark and surgical approach were explored. Four patients with frontal sinus atresia and frontal sinusitis after Drafâ ¡b surgery in Eye & ENT Hospital of Fudan University were retrospectively analyzed. Descriptive method was used to analyze the data. Results:The bottom wall of bilateral frontal sinus was removed, and the bilateral frontal sinus was enlarged above the nasal septum to form a large common cavity. The uncinate process and ethmoid bubble were retained, and the midline drainage of the affected frontal sinus in the healthy side of the nasal cavity was completed. From August 2022 to April 2023, 4 patients with frontal sinus atresia and frontal sinusitis after Drafâ ¡b surgery for unilateral frontal sinus papilloma in Eye & ENT Hospital of Fudan University were treated with surgery. The headache symptoms disappeared after surgery, and the drainage of frontal sinus was spacious, the mucosa healed well and the drainage was unobstructed under endoscopy. There were no other postoperative complications. Conclusion:Drafâ ¢ approach to unilateral frontal sinus for contralateral drainage can drain the affected frontal sinus adequately. The essence of this operation is to drain the bilateral frontal sinus in the unilateral nasal cavity, and this operation has short path, less trauma, and a broader prospect, which is suitable for promotion.

We encountered a case involving a brain abscess in the right frontal lobe of a 12-year-old girl who was diagnosed with a chief complaint of headache and nausea. Left maxillary sinusitis, a dental infection related to dental caries and apical periodontitis, was observed in the left maxillary first molar in addition to left frontal sinusitis also being present. In addition to administering antibacterial agents, extraction of the left maxillary first molar and drainage of the paranasal sinuses and brain abscess were performed. Follow-up over the course of 1 year and 5 months indicated that the patient had progressed without any sequelae; therefore, the prognosis was good. In this case, although bone destruction was observed in the posterior wall of the frontal sinus, which could be a route for bacteria to enter the skull, we considered the possibility of direct invasion from the same site to be low because the brain abscess occurred on the opposite side. We believe that a route for hematogenous invasion from apical periodontitis, in addition to sinusitis, is also possible. Regardless of the route, the outset was an infection in the dental field; therefore, this case reaffirmed the importance of dental cavity treatment in childhood.

Mucoceles of the paranasal sinuses are benign, expansile lesions that develop secondary to sinus ostia obstruction. Presenting signs and symptoms vary widely but frequently include frontal headache and swelling, as well as visual changes and globe displacement depending on orbital involvement in the case of frontal sinus mucoceles. Given the potential for orbital or intracranial involvement, urgent imaging with computed tomography (CT) is important for patients with symptoms concerning for a frontal sinus mucocele. Definitive treatment is surgical. In this article, we report a case of a 50-year-old male who presented to a primary care clinic with a painful forehead mass, found to have a frontal sinus mucocele with erosion through the frontal bone that was eventually treated surgically. We also summarize presenting signs and symptoms of frontal mucoceles reported in the literature as these are important for clinicians to be familiar with, considering the potential emergent complications.

Objective:To explore the characteristics and therapeutic strategies of Pott's puffy tumorï¼PPTï¼. Methods:The clinical data of two patients with PPT were retrospectively analyzed and combined with the literature, focusing on the comprehensive analysis of perioperative diagnosis and treatment strategies. Both patients underwent muti-disciplinary treatment, including timely administration of sufficient antibiotics capable of penetrating the blood-brain barrier. Early removal of PPT lesions was performed using a combined internal and external approach under nasal endoscopic guidance. Results:After standardized perioperative management, the symptoms of the two patients were completely relieved, with no recurrence after one=year follow=up. Postoperative complications such as frontal pain, numbness, local depression, or scar hyperplasiawere not present. Conclusion:PPT, being relatively rare and severe, requires careful attention. Key strategies for standardized perioperative management include multi-disciplinary consultation, timely and adequate antibiotic administration, and surgical intervention using a combined intranasal and extranasal endoscopic approach for lesion removal.

Surgical treatment of inflammatory diseases of the frontal sinus is one of the biggest challenges of modern otorhinolaryngology. Close proximity of the frontal sinus and frontal sinus drainage pathways to the skull base, the orbit and the anterior ethmoid artery, great limitations with its visualization and instrumentation, and high risk of the frontal recess scarring cause difficulties in either endoscopic or external approaches to the frontal sinus. At the same time endoscopic approach to the frontal sinus is considered as preferred method of frontal sinusitis surgical treatment by majority of peers nowadays. The introduction of extended approaches to the frontal sinus pathology treatment with frontal sinus floor and interfrontal sinus septum drill-out as well as superior septectomy with common drainage pathway formation gave an opportunity to greatly decrease a rate of indications for external frontal sinus procedures. In this paper historical backgrounds of endonasal approaches to frontal sinuses are presented, current controversies in proper selection of extent and methods of the frontal sinus surgery are analyzed and endoscopic as well as external approaches to frontal sinuses are summarized.

BACKGROUND: Pott's puffy tumor (PPT) is a rare complication of frontal sinusitis. Although it may occur at any age, the incidence is higher during adolescence. METHODS: We report a series of 10 pediatric patients (9-17 years of age) who presented with PPT in 2 tertiary care pediatric hospitals in central Israel between January 2018 and August 2022 and review the published literature on pediatric PPT. RESULTS: The most common clinical presentations included headache (10 cases), frontal swelling (6 cases) and fever (5 cases). Symptom duration before admission was between 1 and 28 days (median 10 days). The diagnosis of PPT was made by imaging studies at a median of 1 day after admission. All 10 patients underwent computed tomography studies, and 6 patients also underwent magnetic resonance imaging. The overall rate of intracranial complications was 70%. All 10 children were treated with systemic antibiotics and surgical interventions. Streptococcus constellatus group was the most common causal bacteria. All 10 patients recovered uneventfully. CONCLUSIONS: Our findings show that a high index of suspicion for PPT should be applied to adolescents presenting with prolonged headache and frontal swelling. Contrast-enhanced computed tomography is an appropriate first tool for the evaluation; however, an magnetic resonance imaging should be performed to determine the necessity of intracranial interventional treatments if there is any suspicion of intracranial involvement. Complete recovery can be expected with appropriate antibiotic treatment and surgical intervention in most of the cases.

Pott's puffy tumor (PPT) describes forehead swelling with associated frontal bone osteomyelitis and a subperiosteal abscess (SPA) requiring a high suspicion index for optimal outcomes. PPT is a life-threatening complication of frontal sinusitis typically found in adolescents. Our case is one of the youngest in the literature. This report describes a 3-year-old patient who developed multifocal abscesses in the epidural space with frontal and orbital SPA, requiring surgical intervention. Additionally, her course was complicated by a superior sagittal venous thrombosis, a complication commonly associated with PPT. We present an unusual case of orbital SPA and aim to highlight a life-threatening pediatric condition that is often underrecognized.

OBJECTIVE: Low incidence of Pott's Puffy tumor (PPT) has caused studying risk factors and recurrences of the disease to be difficult. We used the comparatively increased incidence at our institution to evaluate potential risk factors for the disease process itself and prognostic factors for recurrence of the disease. METHODS: Single institutional retrospective chart review identified 31 patients from 2010 to 2022 with PPT compared with a control group of 20 patients with either chronic rhinosinusitis or recurrent sinusitis. Patient mean age of PPT was 42 (range of 5 to 90) with the majority of the patient population as male (74%) and Caucasian (68%) in the setting of rural West Texas. Patient mean age of the control group was 50.7 (range of 30-78) with majority of patient population as male (55%) and Caucasian (70%). Interventions studied were functional endoscopic sinus surgery (FESS), FESS with trephination, and cranialization with or without FESS to compare prognostic factors for recurrence rates of PPT. These patients' prognostic risk factors for recurrence and risk factors to develop PPT were analyzed using Analysis of Variance (ANOVA) χ 2 statistical analysis with Fischer exact testing. RESULTS: Mean age was 42 years (range of 5-90) with the majority of the PPT patient population as male (74%) and Caucasian (68%) with an overall incidence of about 1 in 300,000. Pott's Puffy tumor patients were significantly favored in the younger and male population compared with the control patients. Risk factors of no prior allergy diagnosis, previous trauma, medication allergy to penicillin class or cephalosporin class, and lower body mass index were significant in the PPT population compared with the control group. Significant prognostic factors for recurrence of PPT were prior history of sinus surgery and operative treatment choice. Fifty percent (3/6) of patients with prior sinus surgery had recurrence of PPT. Of our 4 treatment options (FESS, FESS with trephination, FESS with cranialization, or cranialization alone), ;FESS had a recurrence of PPT of 0% (0/13), FESS with trephination had a recurrence of PPT of 50% (3/6), FESS with cranialization had a recurrence of PPT of 11% (1/9), and cranizalization alone had a recurrence of PPT of 0% (0/3). Of note, postop chronic rhinosinusitis was seen in 46% (6/13) of FESS alone, 17% (1/6) with FESS with trephination, 0% (0/9) with FESS with cranialization, and 33% (1/3) with just cranialization alone. CONCLUSIONS: Pott's Puffy tumor patients were younger and predominately male when compared to the control patients. No prior allergy diagnosis, previous trauma history, medication allergy to penicillin class or cephalosporin class, and lower body mass index are risk factors for PPT. There are 2 prognostic factors that predict recurrence of PPT: first operative treatment choice and prior sinus surgery. History of prior sinus surgery tends to increase the recurrence of PPT. The first operative treatment plan is the best shot at definitively treating PPT. Correct management surgically can prevent recurrence of PPT as well as long-term recurrence of chronic rhinosinusitis. With early diagnosis and mild disease, FESS is sufficient to prevent recurrence of PPT but chronic sinusitis may continue to occur if frontal sinus outflow track is not well opened. If considering trephination, a definitive cranialization may be more suited for more advanced disease since our study showed 50% of recurrence of PPT with trephination and FESS along with 17% chronic sinusitis long term. More advanced diseases with higher WBCs and intracranial extension do better with more aggressive surgical management with a cranialization with or without FESS which shows to reduce rates of PPT recurrence significantly.

BACKGROUND: Pott's puffy tumor (PPT) is a rare and potentially deadly complication of frontal sinusitis consisting of subperiosteal abscess and osteomyelitis of the frontal bone. CASE PRESENTATION: We report the case of a 9-year-old boy who presented with fever and soft tissue swelling of the forehead. Magnetic resonance imaging (MRI) depicted an abscess in the subcutaneous tissue frontally and an epidural empyema, while a cranial computed tomography (CT) scan revealed bone erosion as a sign of osteomyelitis. The patient was treated accordingly. CONCLUSIONS: This rare condition is essential to keep in mind as it needs a multidisciplinary approach and relevant imaging to start proper treatment and thus decrease the risk of intracranial complications.

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.

OBJECTIVES: Frontal sinus obliteration is often performed using fat, autologous bone or a range of synthetic materials. This paper reports the long-term clinical and radiological outcomes of frontal sinus obliteration using beta-tricalcium phosphate putty. METHODS: A retrospective audit was performed of patients who underwent frontal sinus obliteration with beta-tricalcium phosphate putty. Patient-, disease- and procedure-related data were collected. Pre- and post-operative computed tomography scans were reviewed to assess bone integration. RESULTS: Four patients underwent frontal sinus obliteration using beta-tricalcium phosphate putty for treatment of a cerebrospinal leak, mucocele and recalcitrant frontal sinusitis. All patients had disease resolution, with no intra- or post-operative complications reported in the 16.5-month follow up. Post-operative computed tomography scans confirmed native bone obliteration of the frontonasal ducts in all patients. CONCLUSION: Beta-tricalcium phosphate putty is a safe and effective option for bone obliteration of the frontal sinus in a range of pathologies, including cerebrospinal fluid leak.

BACKGROUND: To describe clinical presentations of intracranial sinusitis complications in childhood, their pitfalls and imaging findings. MATERIEL AND METHODS: This retrospective IRB-approved single-center study included infants diagnosed with sinusitis and empyema and/or other intracranial complications who underwent imaging between September 2008 and September 2019. Three radiologists individually reviewed clinical charts and imaging findings, including sinusitis complications and at-risk anatomical variations. RESULTS: 21 children (76% males and 24% females, mean age 13±3.1 years) with imaging pansinusitis were included. Headache (95%) and fever (90%) were the main clinical nonspecific signs. Ten (48%) children presented an extradural empyema, nine (43%) children had a subdural empyema and two (10%) children had both. Frontal location sinusitis was the most common (76%). In MRI, all empyema presented as a hypo intensity on pre-contrast T1-WI, a hyperintensity on T2-WI, a reduced apparent diffusion coefficient (ADC) on diffusion weighted imaging (DWI) and a peripheral contrast enhancement on post-contrast T1-WI. CT or MRI revealed intracranial complications such as a collection size increase (52%), a midline shift (62%), intraparenchymal abscesses (24%), a cerebral venous thrombosis (29%), an intracranial pressure increase (29%), cerebral ischemia (43%) and Pott's Puffy Tumor (10%). Imaging highlighted sinus anatomical abnormalities in 52% of cases. All children were treated with sinus drainage and/or neurosurgery. Long-term follow-up was favorable in 14 cases (67%). CONCLUSION: Complications of sinusitis are life threatening in the studied population. Empyema and cerebral complications may be misleading. Brain contrast-enhanced CT covering sinuses and orbits, is mainly the first examination done but MRI is mandatory.

Chronic sinusitis ï¼CRSï¼ is one of the most common nasal diseases, and FSDP is a risk factor for CRS. The variation of the frontal recess cell obstructs the frontal sinus drainage pathway, which makes the frontal sinus surgery more difficult and a higher recurrence rate than other sinus surgeries. Therefore, before surgery, a thin-slice CT scan is performed on the patient to fully evaluate the anatomical structure and drainage pathway of the frontal sinus, and to understand the variation of FSDP cell is crucial for accurate opening of the frontal sinus. In this paper, A case of large supra bulla frontal cell infection was summarized and analyzed. The anatomical structure of the frontal recess was fully understood by preoperative radiographs, the spatial relationship between the cells was identified, and the appropriate surgical plan was developed, which was beneficial for the surgeon to accurately open the frontal cortex during surgery and avoid postoperative recurrence.

The aim of this study was to review different approaches and outcomes in the management of post-COVID-19 frontal sinus fungal osteomyelitis. The study included 19 patients with frontal sinus fungal osteomyelitis. The main line of treatment was surgical debridement (sequestrectomy). Approaches included combined external and endoscopic approaches (n = 15) and pure endoscopic approaches (n = 4) according to the extent and accessibility of the sequestrum. Postoperative healing was satisfactory in all patients. All patients returned to their normal daily activity within 4-6 weeks, without residual or recurrent frontal sinus infection, osteomyelitis or need for revision procedures. Within the limitation of this case series, it seems that there is no need to adopt a new therapy regimen for treatment of frontal sinus fungal osteomyelitis because the conventional and well-known treatment approach combining surgery and antifungal drugs seems to work well. However, early, and adequate debridement and sequestrectomy is crucial. Furthermore, an open approach may be required according to the extent of osteomyelitis.
