[Characteristics and therapeutic strategies of Pott's puffy tumor].

Objective:To explore the characteristics and therapeutic strategies of Pott's puffy tumor（PPT）. 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.

Pott's puffy tumor: A rare complication of sinusitis. A case report. / El tumor inflamatorio de Pott: una complicación infrecuente de la sinusitis. Reporte de caso.

A rare complication of frontal sinusitis includes Pott's puffy tumor. It manifests as a swelling of the forehead due to the presence of a subperiosteal abscess secondary to osteomyelitis of the frontal bone. A timely diagnosis allows for an early, intensive medical and surgical treatment, which is critical to prevent serious intracranial complications. Here we describe the case of a 12-year-old boy with Pott's puffy tumor as a complication of pansinusitis. This case was a diagnostic challenge; however, a timely treatment allowed for a favorable clinical course.

Una complicación infrecuente de la sinusitis frontal es el tumor inflamatorio de Pott. Se manifiesta como una tumefacción en la frente por la presencia de un absceso subperióstico secundario a una osteomielitis del hueso frontal. El diagnóstico oportuno permite un tratamiento intensivo médico y quirúrgico precoz, esencial para evitar complicaciones intracraneales graves. Se presenta el caso de un varón de 12 años con un tumor inflamatorio de Pott como complicación de una pansinusitis. Representó un desafío diagnóstico; sin embargo, la instauración del tratamiento oportuno permitió una evolución clínica favorable.

Pott's Puffy Tumor: A Rare, Life-Threatening Presentation of Periorbital Edema.

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.

Pott's Puffy Tumor in Pediatric Patients: Case Series and Literature Review.

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: First Shot is the Best Shot.

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.

A 9-year-old boy with a nonmalignant forehead tumor - a rare case of pediatric Pott's puffy tumor.

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.

Intracranial empyema complicating sinusitis in childhood: Epidemiology, imaging findings and outcome.

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.

Management of frontal sinus fungal osteomyelitis in the COVID 19 era: A case series.

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.

Frontal Bone Osteomyelitis in Adult.

Frontal bone osteomyelitis is a rare clinical disease which occurs as a result of frontal sinusitis, penetrating injury on head, post-operative complication after sinus surgery and hematogenous spread from distant site. Early diagnosis, appropriate surgical debridement and antibiotic are keys to prevent from life threatening intracranial complications. We report a 63 years old male patient with osteomyelitis of outer cortex of frontal bone. The wound was thoroughly debrided after computer tomography scan showed an osteolytic lesion on outer table of fontal bone and antibiotic was continued for 2 months until inflammatory markers become normal.

[The efficacy of the extended endoscopic frontal sinus drill-out in cases of repeatedly operated polypous-purulent pansinusitis accompanied by a whistle in the front wall of the frontal sinus]. / Effektivnost' rasshirennoi endonazal'noi endoskopicheskoi frontotomii pri mnogokratno operirovannom khronicheskom polipozno-gnoinom pansinusite, oslozhnennom formirovaniem svishcha perednei stenki lobnoi pazukhi.

Treatment of patients with severe chronic and recurrent forms of frontal sinusitis, often caused by scarring as a result of repeated interventions in the frontal sinuses, is a difficult task. In such cases, for adequate drainage of the frontal sinus and ensuring stable patency of the nasolabial anastomosis, an endoscopic extended frontotomy can be the choice operation, the possibility of which certainly depends on the experience of the surgeon, anatomical features of the structure of the frontal sinus and the nature of the pathological process. The article shows the effectiveness of surgical treatment of chronic purulent frontal sinusitis that developed after 5 interventions on the paranasal sinuses with external and combined access, accompanied by the development of a fistulous passage of the anterior wall of the frontal sinus. For wide drainage of the frontal sinus and stable preservation of patency of the nasolabial fistula, the patient underwent extended endoscopic frontotomy (Draf III operation according to the international classification).

Pott Puffy Tumor Caused by Dental Infection: A Case Report and Literature Review.

ABSTRACT: Pott puffy tumor (PPT), first described by Sir Percivall Pott in 1760, is a rare clinical entity characterized by a subperiosteal abscess associated with osteomyelitis of the frontal bone caused by direct or hematogenous spread. Although rare in this modern age of antibiotics, this tumor usually occurs as a complication of sinusitis. Moreover, intracranial complications such as subdural abscess, meningitis, sinus thrombosis, or brain abscess can occur concomitantly with the underlying sinusitis, despite the administration of antibiotics. Herein, we present the case of a 48-year-old man who was diagnosed with PPT using computed tomography and treated medically and surgically. The infection remained uncontrollable after surgery and drain removal, owing to the persistence of the original dental focus of the infection. This case highlights the importance of treating the source of the infection in addition to the local area of inflammation, to facilitate complete infection control in PPT.

Odontogenic Sinusitis-Associated Pott's Puffy Tumor: A Case Report and Literature Review.

Pott's puffy tumor (PPT) is a nonneoplastic complication of acute frontal sinusitis characterized by subperiosteal abscess (SPOA) formation and osteomyelitis. Although various clinical conditions are associated with frontal SPOA, cases associated with odontogenic sinusitis are rare. We report a recurrent case of frontal SPOA who had a previous history of craniotomy due to head trauma. The patient was presented with headache, facial swelling and diagnosed as frontal, ethmoid, and maxillary sinusitis with frontal SPOA, which is PPT. The patient was surgically managed by endoscopic sinus surgery and external drainage of the abscess. Although the symptoms had been relieved soon after the surgery, they were recurred after 1 week. By paranasal sinus computed tomography scans, it was suspected that severe carious teeth, which were missed before surgery, induced maxillary sinusitis which spread into the frontal sinus and subperiosteal areas inducing recurrence of disease. Our experience suggests that frontal SPOA may originate from odontogenic maxillary sinusitis caused by severe dental caries, which should be actively managed, especially in patients with the risk of spread of inflammation, such as those who have discontinuity in frontal bone.

Pott's puffy tumor in a 23-month-old: Youngest known case of a rare disease.

This case report describes a child who developed Pott's puffy tumor and was treated at the Children's Mercy Hospital in Kansas City. In addition to a discussion of a case, a review of the literature was completed on this topic describing the typical embryology and development of the frontal sinus, and the epidemiology, diagnosis, and treatment of Pott's puffy tumor. The patient was a 23-month-old boy who developed Pott's puffy tumor after recovery from influenza. The patient presented to the hospital with progressing edema of the unilateral eye that spread bilaterally within a few days. A CT scan demonstrated pansinusitis, developed frontal sinuses, right periorbital cellulitis, and medial forehead subperiosteal abscess. Functional endoscopic sinus surgery and transcutaneous abscess drainage were urgently performed and the patient made a full recovery following a course of ertapenem and levofloxacin. The presence of a developed frontal sinus in a 23-month-old is an unexpected radiologic finding. This case represents the youngest patient reported in the literature to develop this rare complication of frontal sinusitis.

Assessment of the necessity of frontal sinostomy in cases of frontal sinusitis associated with fungus ball of the maxillary sinus.

PURPOSE: This study was conducted to evaluate outcomes in patients presenting with fungus ball of the maxillary sinus (MSFB) and frontal sinusitis who were treated via middle meatal antrostomy alone. METHODS: This was a randomized, controlled study with a parallel group design. Patients with MSFB and frontal sinusitis were randomly assigned to the maxillary middle meatal antrostomy (MMMA) or control (MMMA + frontal sinusotomy) groups. Patient demographics, complaints, imaging findings were analyzed, and surgical outcomes were evaluated using the Lund-Kennedy endoscopic score (LKES) and the 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaire. RESULTS: In total, 40 patients were separated into two groups, with similar symptoms including nasal obstruction, mucopurulent rhinorrhea, maxillary or frontal pain, blood stained nasal discharge, nasal cacosmia and orbital pain being observed in both groups. Total LKES and SNOT-22 scores were significantly improved in both groups at 6 months post-treatment, with no significant differences in these scores between groups within a mean 6.8-month follow-up. CONCLUSION: These results suggest that frontal sinusotomy is not required to resolve frontal sinusitis associated with MSFB. As such frontal sinusitis appears to be a reactive process caused by fungal ball obstruction, it regresses spontaneously following fungus ball removal, drainage of the maxillary sinus, and middle meatal antrostomy.

Pott's Puffy Tumour: a rare but sinister cause of facial swelling.

A 27 year old female presented to the emergency department with intermittent central forehead swelling over several months associated with a headache. She was admitted under the medical team as having had a suspected allergic reaction but the diagnosis of a Pott's Puffy Tumour was quickly made and confirmed through CT and MR imaging. This uncommon condition is related to sinusitis leading to localised abscess formation with osteomyelitis and a subsequent swollen appearance over the affected facial sinus. This patient's sinus abscess extended into the epidural space and caused destruction of the anterior and posterior walls of the frontal sinus. The patient was managed with intravenous antibiotics, analgesia and referral to the local ENT team for surgical intervention.

Complicated acute frontal sinusitis in a child presenting with acute ischemic stroke.

Acute stroke as a complication of sinusitis is exceedingly rare, and even more so in children. Here we present the case of a healthy 9-year-old male who had an acute stroke in the setting of severe acute pansinusitis. The patient was started on parenteral antibiotics and underwent urgent endoscopic sinus surgery and adenoidectomy, ultimately making a full neurologic recovery. Of the previously reported cases of stroke as a complication of sinusitis, all showed evidence of carotid artery pathology. This is the first report to our knowledge of acute sinusitis presenting as stroke with normal arterial anatomy and function.
