Pott's Puffy Tumour: A Rare Complication of Sinusitis.

Pott's puffy tumour is a rare entity defined by the presence of a subperiosteal abscess of the frontal bone associated with frontal osteomyelitis. Several predisposing conditions can lead to this entity, such as frontal sinusitis. We report the case of a 15-year-old patient who presented to the emergency department for headache, fever and forehead swelling. Computed tomography revealed severe pansinusitis complicated by a subperiosteal abscess associated with frontal osteomyelitis, leading to the diagnosis of Pott's puffy tumour. The management combined intravenous antibiotics and surgical drainage of both the sinusitis and subperiosteal abscess. Pott's puffy tumour represents a rare but serious complication of frontal sinusitis. Clinicians should be aware of this potential complication as the diagnosis can be challenging at an early stage but may influence the subsequent prognosis. Pott's puffy tumour is a rare but severe complication of frontal sinusitis.The main symptoms are fever, headache, rhinorrhoea, and forehead swelling.Early diagnosis and treatment can prevent neurological sequelae and associated mortality.

Ultrasonography for the Detection of Osteomyelitis in Pediatric Patients With Soft Tissue Infection: A Pilot Study.

To demonstrate the usefulness of ultrasonography for differentiating soft tissue infections with or without osteomyelitis in pediatric patients who underwent ultrasonography and subsequent magnetic resonance imaging (MRI). Twenty-three patients were classified into 2 groups: 12 patients with and 11 patients without osteomyelitis based on MRI. Osteomyelitis using ultrasound is characterized by the presence of bone cortex irregularity and/or subperiosteal abscess formation. The diagnostic performance of ultrasonography for detecting osteomyelitis and subperiosteal abscess formation was compared with that of MRI. Diagnostic accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were calculated with 95% confidence intervals (CIs). Of 12 osteomyelitis cases, 11 had abnormal bone marrow enhancement (one residual case did not undergo contrast enhancement study) and 5 had subperiosteal abscesses. The diagnostic accuracy of ultrasonography for osteomyelitis was 82.6% (number of correct diagnosis of osteomyelitis/total number = 19/23; 95% CI, 61.2-95.0) and for detecting periosteal abscess was 95.7% (number of correct diagnosis of periosteal abscess/total number = 22/23; 95% CI, 78.1-99.9), respectively. The sensitivity and specificity of ultrasonography for detecting osteomyelitis were 66.7% (95% CI, 34.9-90.1) and 100% (95% CI, 71.5-100), respectively. The sensitivity and specificity of ultrasonography for detecting periosteal abscess were 80% (95% CI, 28.4-99.5), and 100% (95% CI, 81.5-100), respectively. One-third of osteomyelitis cases could not be detected using ultrasonography. Ultrasonography may be useful for diagnosing osteomyelitis in pediatric patients; however, the technique appears limited by low sensitivity. However, it is more accurate for diagnosis of periosteal abscess in these patients.

Recurrent Orbital Subperiosteal Abscess in Patient with Nasopharyngeal Carcinoma

Introduction : Subperiosteal abscess (SPA) is a rare finding in cancer patients with orbital cellulitis. Severe complications associated with this condition are permanent visual loss, intracranial extension, and death.
 Case Illustration : A 38-year-old male with history of nasopharyngeal carcinoma (NPC) came with progressive right eyelid swelling, non-axial proptosis, and visual acuity was NLP. CT scan revealed right SPA associated with frontal sinusitis. NPC staging was T3N2M0. Despite the treatment of intravenous antibiotics and drainage incision of SPA, there was recurrence of right SPA two weeks after procedure and re-staging revealed T4N3M0. A joint operation with otolaryngology department to do debulking of the mass, frontal sinus surgery, and drainage incision was held. Culture resulted in Talaromyces marneffei. Patient was assessed with talaromycosis and given itraconazole for ten weeks. Moreover, patient came again with proptosis seven weeks postoperatively. Re-drainage incision was performed and clinical presentation was improved.
 Discussion : This case describes rare biological nature of NPC where extensive blockage of paranasal sinuses allows microorganism overgrowth and infection. The anatomical changes and cancer-related immunosuppression contribute to recurrent SPA. Chemotherapy and radiotherapy are ideal treatments for our patient, however, infection must be treated adequately first. Surgical interventionis needed to manage the infection by SPA drainage where antimicrobial has poor penetration into the abscess and debulking of tumor to clear the blockage of drainage pathway.
 Conclusion : Recurrent orbital SPA could happen in patients with NPC, therefore appropriate medical treatment and timely surgical intervention are essential in managing orbital SPA. Multidisciplinary management is required to optimize patient outcomes.

Acute coalescent mastoiditis in a 16-month-old child due to Streptococcus pneumoniae infection

Rationale: Acute otitis media is a common disease in early childhood, and is usually caused by Streptococcus pneumoniae (S. pneumoniae). Acute mastoiditis is a complication of acute otitis media and can involve not only the mucoperiosteum of the middle ear but can also spread to the periosteum by destroying the mastoid bone (acute coalescent mastoiditis). In addition, the infection can extend through the surrounding bones or the emissary veins beyond the mastoid's air cells, leading to subperiosteal abscesses. Patient's Concern: A 16-month-old female patient was hospitalized due to the purulent discharge of the left ear and the symptoms of right mastoiditis (swelling and redness of the skin). Diagnosis: Bilateral acute coalescent mastoiditis caused by S. pneumoniae infection. The computer tomography revealed bilateral bone destruction of the mastoid and abscesses found behind the auricle on both sides. Interventions: The patient underwent intravenous antibiotic therapy and surgical treatment. Outcomes: The patient was discharged 14 days after hospitalization with an improved condition. Lessons: Improperly treated acute coalescent mastoiditis can lead to extracranial and intracranial complications, sometimes serious and even life-threatening. Complications are prevalent in children under 2 years, in whom the disease progresses more rapidly and severely. The vaccination with a 13-valent vaccine may not result in sufficient immunity against S. pneumoniae, a predominant pathogen in children affected by acute coalescent mastoiditis.

Malignant type of chronic suppurative otitis media with subperiosteal abscess complications: A case report

A 16-year-old male patient suffers from malignant Chronic Suppurative Otitis Media (CSOM) with subperiosteal abscess complication. The patient has a history of intermittent discharge from the right ear, since his age of 9 years old and never received any treatment. Ear examination was normal in the left ear. In the right ear, the external acoustic canal is narrow, there is no discharge and the tympanic membrane is difficult to evaluate. Examination of the nose revealed no abnormalities. The throat examination revealed no abnormalities. In the right temporoparietal region, there was a lump measuring 9x8 cm, redness, tenderness, warmth and fluctuating. In this patient, incision and drainage were performed. Furthermore, we did dilatation and drainage of the abscess every day until no pus is formed. After that, it was followed by a right canal wall-down mastoidectomy. Intraoperatively, cholesteatoma, granulation, and pus were found in the mastoid cavity, antrum, and tympanic cavity, closing the orifice of the Eustachian tube. Destruction of the incus, scutum, and posterior wall of the external acoustic canal. Perforated tympanic membrane. Tissues suspected of cholesteatoma were examined for anatomic pathology. From the results of anatomical pathology, histomorphology was found to be suitable for cholesteatoma. The principle of therapy for the malignant types of CSOM (with cholesteatoma) is surgery for cholesteatoma eradication and reconstruction. Treatment of subperiosteal abscess includes intravenous antibiotics, incision and drainage of the abscess, and mastoidectomy.

Chronic Suppurative Otitis Media Accompanied by Facial Nerve Paresis: A Case Report

Introduction: Chronic suppurative otitis media (CSOM) is marked by ear discharge (otorrhea) that lasts for more than six to eight weeks, middle ear inflammation that doesn't go away, and a ruptured eardrum. The purpose of this study is to describe examples of CSOM with facial nerve paresis and how such cases are managed.
 Case presentation: A thirty-year-old man complained to the Mataram Community Health Center two days before admission that his mouth was turning to the left, despite the fact that he was still able to speak well. Additionally, for four months, the patient complained of a constant discharge from the right ear. The fluid that emerges from the ear is sticky, yellow, and odorous; blood is not mixed with it. Upon inspection, a cholesteatoma and a flat-edge attic perforation on the tympanic membrane were discovered, together with a purulent and odorous discharge in the ear canal of the right ear. After a facial nerve examination, it was discovered that the forehead wrinkles were uneven and that the face was asymmetrical, with the right eyebrow unable to be raised. The patient was identified as having peripheral facial nerve paresis and persistent suppurative malignant otitis media of the auricula dextra. The patient is being treated with irrigation of the ear canal with 0.9% NaCl, cleaning of the cholesteatoma, and antibiotic administration: two drops of ofloxacin ear drops given twice a day, three times a day ciprofloxacin tablets 500 mg, three times a day methylprednisolone 16 mg, and advice to undergo a mastoidectomy.
 Conclusion: Complications including hearing loss, facial nerve palsy, subperiosteal abscess, petrositis, meningitis, cerebral abscess, and labyrinthine fistula are indicated for mastectomy surgical therapy.

Pediatric preseptal and orbital cellulitis – a 6 year experience from a London tertiary centre

ABSTRACT Purpose This study reports the experience of pediatric preseptal and orbital cellulitis at a London tertiary centre during a 6-year period and highlights the role of orbital surgeons in the management of subperiosteal abscess (SPA). Methods A retrospective review was conducted of all pediatric patients hospitalised for preseptal and orbital cellulitis. Results A total of 201 children including 152 cases of preseptal cellulitis and 49 cases of orbital cellulitis were admitted at a London tertiary centre over the study period. Patients with orbital cellulitis and especially those managed surgically had higher rates of fever, higher presenting white cell count and C-reactive protein level compared to cases of preseptal cellulitis. 77.6% of patients with orbital cellulitis had SPA. 81.6% of SPA had a medial component, while 28.9% had superior component. 61.2% of orbital cellulitis cases were managed surgically. Surgical intervention was carried out by otorhinolaryngologists (ENT) in 76.7% of cases, jointly between ENT and orbital surgeons in 16.7% of cases and by orbital surgeons alone in 6.7% of cases. Of the 11 SPA involving the orbital roof, all were surgically managed and orbital surgeons were involved in 54.5% of cases. When SPA involved the medial wall, orbital surgeons were only involved in 6.5% of cases. Conclusions We recommend all patients with superior SPA be treated at a centre with both ENT and orbital surgeons as these may not be amenable to drainage by ENT alone.

Pott’s puffy tumor a subdurální absces jako komplikace akutní rinosinusitidy – kazuistika

Summary Rhinogenic inflammatory intracranial complications are relatively rare, but they are very serious and can be fatal. The diagnosis is mainly based on anamnesis, objective examination, imaging methods and laboratory findings. Our case study is devoted to an intracranial complication of sinusitis of a 17-year-old patient. It was a subperiosteal abscess with simultaneous subdural abscess in the frontal region and osteomyelitis of the frontal bone. The patient came to the otorhinolaryngology clinic at Jičín Regional Hospital with prolonged rhinosinusitis, after already receiving primary therapy of oral aminopenicillin with a temporary effect. An objective examination revealed slight swelling in the area of the root of the nose and eyelids, rhinoendoscopic swelling of the mucous membranes with mucopurulent secretion in the middle nasal passage on the left. The original suspicion of an orbital complication of rhinosinusitis was ruled out by a CT scan. The patient was hospitalized and treated with intravenous antibiotics, corticoids and the nasal cavity was treated locally and the inflammatory parameters decreased gradually. During hospitalization, swelling of soft tissues progressed frontally, without neurological symptoms. Due to the suspicion that there was an intracranial complication of rhinosinusitis, a CT scan of the paranasal sinuses and brain was performed. The radiologist diagnosed subdural empyema and osteomyelitis of the frontal bones. An acute transfer to the neurosurgery clinic of the University Hospital in Hradec Králové for intravenous antibiotic therapy and surgical intervention by a neurosurgeon and otorhinolaryngologist was arranged. Postoperative healing was favourable. Key worlds paranasal sinuses – sinusitis – subdural abscess – osteomyelitis

Visual outcomes following orbital decompression for orbital infections

ObjectiveTo analyze the visual outcomes and sequelae of endonasal intervention for orbital infections. IntroductionOrbital infections pose a serious threat to vision in the pediatric population and can result in complications such as blindness, diplopia, intracranial involvement, and death. [1] Orbital decompression by endonasal intervention is a common treatment to address a variety of orbital infections including orbital cellulitis, orbital abscesses, and subperiosteal abscesses. [2] The outcomes of visual sequelae such as loss or limitation of visual acuity, extraocular movements, and increased intraocular pressure following orbital decompression via endonasal intervention have not been sufficiently investigated in the current literature. MethodsThis retrospective cohort study was performed at our tertiary care pediatric hospital using data from 69 patients aged 0–18 years who were admitted between 2008-2018. Data was extracted from the electronic medical record system. ResultsFollowing endoscopic sinus surgery, symptoms of orbital infection improved throughout the cohort. Improvement in visual acuity is demonstrated by a statistically significant decrease in the average logMAR value in both the right and left eye (P = 0.002 and P = 0.028 respectively). There was also a significant improvement to normal values postoperatively for patients who initially presented with abnormal tonometry, extraocular movement, and the appearance of eyelids and eyelashes. ConclusionThere is no decline or loss of vision with otolaryngology surgical intervention for orbital cellulitis in our cohort. This retrospective chart review demonstrates the efficacy of surgical intervention on overall visual outcomes following endonasal intervention for orbital infections such as orbital cellulitis, orbital abscesses, and subperiosteal abscesses.

Аcute sinusitis as a cause of orbit phegmon in a newborn child

Orbital complications of varying severity caused by acute sinusitis are relatively common in pediatric practice. These complications develop depending on the anatomical features of the paranasal sinuses and eye sockets in children and immune system impairment.
 AIM: To present a clinical case of orbital phlegmon in a newborn child.
 RESULTS: A 17-day-old female infant was admitted to the Infectious Diseases Department of the Altai Regional Center for Maternal and Childhood Protection. After self-treatment, her health status did not improve; thus, she was hospitalized. After additional instrumental methods of research, the following diagnosis was made: рhlegmon of the left orbit, subperiosteal abscess on the left, and ethmoiditis with destruction on the left. A consultation of specialists (an ophthalmologist, otorhinolaryngologist, and neonatologist) determined the further management approach.
 CONCLUSION: Orbital complications in pediatric practice require an immediate assessment of the clinical condition by an otorhinolaryngologist and an ophthalmologist. The clinical case presented focuses on the need for an interdisciplinary approach and hospitalization in the initial disease stages to provide therapy because the infection may spread to the intracranial region.

Complications of acute mastoiditis in a paediatric population at a UK Tertiary Centre: A retrospective review.

Acute mastoiditis (AM) and its associated intra and extracranial complications are rare complications of acute otitis media. However, they are associated with a high morbidity. The management of AM with complications carries significant variations in approach. We aimed to evaluate the presentation of children with AM with complications to a tertiary referral centre in the United Kingdom and describe evolution of the treatment approaches. We undertook a retrospective chart review ofall children admitted with AM to the University Hospitals of Leicester between 2013 and 2022. Twenty-seven children were included in this study: 7 patients had sigmoid sinus thrombosis (SST), 4 had an intracranial collection, 3 had cranial nerve palsy and 16 had a subperiosteal abscess (SPA); some patients had more than 1 complication. In this study, treatment of SPA with incision and drainage (I&D) and grommet insertion was effective, as all patients treated with grommet insertion and I&D recovered well and did not require a subsequent cortical mastoidectomy. All patients with SST received anticoagulation and intravenous (IV) antibiotics; surgical input consisted of grommet insertion alone and cortical mastoidectomy was not routinely performed in these patients. In our series, management of SPA with grommet insertion and drainage had good outcomes. SST management mainly consisted of IV antibiotics, anticoagulation and grommet insertion with good recovery. The evidence to guide the management of complications of mastoiditis is of poor quality and further research is needed to clarify the optimal management of these complications.

Pott Puffy Tumor Secondary to Cranial Vault Reconstruction in a Patient With Metopic Craniosynostosis.

Pott puffy tumor (PPT) is defined as a subperiosteal abscess of the anterior wall of the frontal sinus associated with underlying frontal osteomyelitis. PPT affects all age groups but occurs predominantly in adolescents. The potential etiologies include rhinosinusitis, a history of direct trauma to the forehead, odontogenic disease, intranasal drug abuse, diabetes, or other immunocompromised states. We introduce a case of a 6-year-old boy with a medical history of anterior cranial vault remodeling presenting with localized forehead swelling. Computed tomography imaging demonstrated mucosal thickening and a region of dehiscence in the wall of the frontal sinus; the presence of midline subperiosteal abscess was consistent with a diagnosis of PPT. Due to concerns for intracranial involvement, we utilized removal and replacement of the anterior wall of the frontal sinus, complete removal of sinus mucosa, and frontal sinus obliteration with bilateral peri-cranial flaps. To the best of our knowledge, this is the first case description of a PPT secondary to cranial vault reconstruction in a patient with metopic craniosynostosis.

High-resolution ultrasound in the evaluation of musculoskeletal infections.

Soft tissue and osseous musculoskeletal infections are common but can be difficult to diagnose clinically. Signs, symptoms, and physical examination findings may be nonspecific, and laboratory values can be inconclusive. The extent of disease may also be underestimated on physical examination. Soft tissue infections most commonly occur secondary to direct inoculation from broken skin and less frequently due to the seeding of the soft tissues from hematogenous spread, while osseous infections are more commonly due to hematogenous seeding. Infections may also be iatrogenic, following surgery or other procedural interventions. High-resolution ultrasound is an extremely useful imaging modality in the evaluation of musculoskeletal soft tissue and joint infections, and can occasionally be used to evaluate osseous infections as well. Ultrasound can aid in the early diagnosis of musculoskeletal infections, allowing for prompt treatment, decreased risk of complications, and treatment optimization. Ultrasound is sensitive and specific in evaluating soft tissue edema and hyperemia; soft tissue abscesses; joint, bursal and tendon sheath effusions/synovitis; and subperiosteal abscesses. This article describes the typical high-resolution grayscale as well as color and power Doppler ultrasound imaging findings of soft tissue infections including cellulitis, fasciitis, necrotizing deep soft tissue infection, pyomyositis, soft tissue abscess, infectious bursitis, and infectious tenosynovitis. Ultrasound findings of septic arthritis as well as osteomyelitis, such as subperiosteal spread of infection (subperiosteal abscess). are also reviewed. In addition, the use of ultrasound to guide fluid and tissue sampling is discussed.

Pediatric orbital subperiosteal abscess outbreak in Iran: characteristics and causes.

To evaluate demographics, characteristics, and management of pediatric patients with subperiosteal abscesses (SPA) secondary to orbital cellulitis and discuss the etiology of a dramatic rise in SPA. Data were gathered by retrospective chart review of patients admitted to a tertiary referral eye hospital (Farabi Eye Hospital) diagnosed with orbital cellulitis with subperiosteal abscess from October 2022 to March 2023 (six months). Data on demographic information, clinical examination, radiographic evidence of sinusitis, orbital cellulitis, SPA, surgical and non-surgical management taken, isolated bacteria, and duration of hospital stay were gathered. 24 patients were admitted during these six months, with a diagnosis of orbital SPA secondary to paranasal sinusitis, confirmed by an orbital Computed Tomography (CT) scan. The age range was 11 months to 16 years. 75% of patients were male. All patients had a history of flu-like illness before developing orbital cellulitis. All patients had concurrent sinusitis, and 18 underwent initial surgical abscess drainage. The ethmoid sinus was the most involved, and most patients had a medially located SPA. Abscess volume ranged from 0.78 to 7.81 cm3 (mean: 3.52 cm3). One patient had concurrent central retinal artery occlusion due to orbital cellulitis. In this study, we report a dramatic increase in the incidence of SPA referred to our hospital. Larger abscess volumes and an increased number of cases that needed initial surgical drainage are also of note. An influenza outbreak in the autumn and winter, undiagnosed Corona Virus Disease 2019 (COVID-19) infection, increased antimicrobial resistance due to excessive off-label use of antibiotics during the COVID-19 pandemic, and more virulent bacterial infections are the most probable hypotheses to justify this observation.

Bugs Behind the Bulging Eyeball: Microbiology and Antibiotic Management in Orbital Cellulitis With or Without Subperiosteal Abscess.

The objective of this study is to describe causative pathogens and current antibiotic management among hospitalized children with orbital cellulitis. This retrospective study, performed at a tertiary care children's health system, included patients up to 18 years old who presented with radiographic evidence of orbital cellulitis from 2012 to 2019. Of the 298 patients included in the study, 103 had surgery and an intraoperative culture obtained. A pathogen was recovered in 86 cultures (83.5%). The most common pathogens were Streptococcus anginosus group (26.2%), Streptococcus pyogenes (11.7%), methicillin-susceptible Staphylococcus aureus (10.7%), and Streptococcus pneumoniae (9.7%). Only 8/194 (4.1%) blood cultures returned positive. Median duration of intravenous antibiotics was 4 days and median total duration was 17 days. The most common empiric regimen prescribed was ceftriaxone and clindamycin (64.1%). Despite low incidence of methicillin-resistant S aureus, empiric antibiotics often consisted of 2 antibiotics to ensure coverage for this bacterium.

Revisiting the orbital complications of acute rhinosinusitis

ObjectiveThe present study revisited three classification systems of orbital complications of acute rhinosinusitis (ARS) (Chandler, Mortimore & Wormald, and Velasco e Cruz & Anselmo-Lima) and observed which of them presented the best clinical applicability. MethodsClinical data and CT scan findings of patients with orbital infection were retrospectively collected. To compare the three classification systems, we revised and graded all CT images accordingly, and divided the patients into four groups: Eyelid cellulitis (EC), orbital cellulitis (OC), subperiosteal abscess (SA), and orbital abscess (OA). The groups were compared regarding the presence of sinus opacification, the need for hospitalization and/or surgical treatment, and the presence of further complications/sequelae. Results143 patients were included. The median number of sinuses involved in patients in the OC, SA, and OA groups was 2.0. ARS was rarely associated with signs of EC (present in both Chandler’s and Mortimore & Wormald’s classifications. The hospitalization rate was significantly lower in the EC group compared to the other three groups. Surgery was performed in all cases in the OA group, in 58.1% in the SA group, 19.4% in the OC group, and 12.5% in the EC group (p-value < 0.0001). Complications were present at higher rates in the OA group compared to the other three groups. ConclusionsARS was rarely associated with Eyelid Cellulitis. The stratification in the other three groups showed to be clinically relevant. Velasco e Cruz & Anselmo-Lima’s classification system proved valid, simple, and effective for categorizing orbital complications of ARS. Level of evidence3.

Subperiosteal and Orbital Abscesses: A Comparison of Clinical Features, Management, and Outcomes.

To compare the clinical features, management, and outcomes between orbital cellulitis patients with subperiosteal abscess (SPA) and those with orbital abscess (OA). A retrospective study was conducted at a tertiary care center through medical record search to identify patients with orbital cellulitis from January 1, 2000 to December 31, 2022. Charts were screened for those with radiographic evidence of SPA or OA. Demographic data and presenting clinical features were compared between the 2 cohorts. Primary outcomes compared included rates of surgical intervention, reoperation, and readmission; and length of hospital stay and final vision. A total of 189 patients, 162 with SPA and 27 with OA, met the criteria. The OA group (mean 46.5 ± 18.6 years) was older than the SPA group (mean 19.1 ± 21.4 years). Comorbid sinusitis was significantly more common in the SPA cohort (95.7% SPA; 70.4% OA; p < 0.001), while OA was more likely to occur with orbital trauma (29.6% vs. 8.0%; p = 0.003), implanted hardware (11.1% vs. 0.6%; p = 0.005), and comorbid diabetes (22.2% vs. 4.3%; p = 0.001). OA patients more often presented with a relative afferent pupillary defect (21.7% vs. 3.9%; p = 0.005), vision worse than 20 of 50 (42.3% vs. 16.2%; p = 0.005), and methicillin-resistant Staphylococcus aureus infection (20.8% vs. 5.8%; p = 0.036). OA was associated with a higher reoperation rate (47.8% vs. 21.3%; p = 0.019), readmission rate (18.5% vs. 5.6%, p = 0.047), and limited extraocular motility at follow-up (4.3% vs. 25%; p = 0.013); while mean length of hospital stay and final visual acuity were similar. OA may affect an older population with a divergent risk factor profile compared with SPA. OA may cause more severe functional impairment on presentation, warranting more aggressive management to achieve visual outcomes similar to SPA.

Orbital and Intracranial Complications of Acute Rhinosinusitis in a Tertiary Center, Saudi Arabia.

Background Rhinosinusitis is an inflammatory condition affecting the nasal cavity's mucosa and paranasal sinuses. In rare cases, acute rhinosinusitis (ARS) might lead to significant orbital and intracranial complications. This study aims to review the patients who presented with orbital or intracranial complications of ARS and to identify the main outcomes of these complications and their prognosis. Methods In this study, aretrospective chart review of patients with orbital or intracranial complications of ARS who presented to the otolaryngology department at King Abdulaziz Medical City, Riyadh, Saudi Arabia from 2016 to 2022 was conducted. Results A total of 43 patients with orbital, intracranial, or both (orbital and intracranial) complications of ARS were included. The most involved sinuses were maxillary sinuses. The most reported orbital complications were subperiosteal abscesses, and the most reported intracranial complications were epidural abscesses. Conclusion Orbital and intracranial complications of ARS are serious and life-threatening if not recognized early and treated effectively. The majority of ARS complications in this study were orbital complications. Fortunately, most of the cases carry a favorable outcome.

Surgical management of mastoiditis with intratemporal and intracranial complications in children. Outcome, complications, and predictive factors.

Intratemporal or intracranial complications of acute mastoiditis are often of significant severity, can be life-threatening, and require prompt and usually aggressive treatment. This study focused on analyzing the outcomes and complications of different surgical techniques used in intracranial and intratemporal complications of acute mastoiditis, the most common complication of acute otitis media. A retrospective study of pediatric patients with mastoiditis with intratemporal and intracranial complications was designed at the Niño Jesús University Children's Hospital in Madrid, Spain, from 2005 to 2021. Of 417 patients with mastoiditis, 112 patients developed intratemporal and intracranial complications, with subperiosteal abscess being the most frequent complication. The most frequently isolated pathogens were Streptococcus pneumoniae, Streptococcus pyogenes, and Fusobacterium necrophorum. The most used surgical technique was myringotomy with placement of transtympanic drainage, in 86.6% of all cases. In patients with intracranial complications, neurosurgical procedures were necessary for 19.2%, with craniotomy with mastoidectomy being the most frequent. Most of the cases evolved favorably, and only 5.4% of the patients required surgical reintervention, being more frequent in intratemporal complications. In terms of complications, we found cases of neutropenia in 3.6%, neurological sequelae in 5.4%, and permanent hearing loss in 2.7%. There was a favorable evolution with a low incidence of reoperation and sequelae within our series. The surgical technique of choice correlated with the severity of the complication. If the mean size of the abscess exceeds 20mm, incision and drainage, along with myringotomy and tube placement, should be considered as the initial treatment. Closed mastoidectomy should be reserved for deteriorating of clinical evolution or acute mastoiditis with intracranial complications. Intracranial and multiple concomitant complications were associated with a more extended hospital stay, ICU occupancy, neurosurgical intervention, and risk of neurological sequelae and neutropenia. Conversely, intratemporal complications may result in permanent hearing loss.

Pott's Puffy Tumor: A Rare, Life-Threatening Presentation ofPeriorbital 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.
