Otogenic Temporomandibular Arthritis in Children

A Pediatric Case of Fusobacterium necrophorum Mastoiditis and Meningitis Case Report in a Healthy Child and Review of the Literature

In infants and children, bacterial meningitis caused by anaerobic bacteria is rare. However, a serious infection with the anaerobe Fusobacterium necrophorum can occur in previously healthy children with a peak incidence in preschool children and in adolescents. As the clinical presentation can be very similar to meningitis caused by aerobic bacteria, one should consider Fusobacterium necrophorum as the causative agent when preceded by or associated with otitis media with purulent otorrhea or mastoiditis, in combination with minimal or no improvement on empiric antibiotic treatment. As this pathogen can be difficult to culture, anaerobic cultures should be obtained. Prompt treatment with a third-generation cephalosporin and metronidazole should be initiated once suspected or confirmed. Surgical source control is often necessary, but even with adequate and prompt treatment, the morbidity and mortality in children with a Fusobacterium necrophorum meningitis remains high. In this report, we describe a case of Fusobacterium necrophorum meningitis in a previously healthy child and review the available literature.

The Clinical Value of Cranial CT Venography for Predicting Fusobacterium necrophorum as the Causative Agent in Children with Complicated Acute Mastoiditis

BACKGROUND AND PURPOSE

Fusobacterium necrophorum (F necrophorum) is an anaerobic bacteria that causes invasive head and neck infections in children. Several studies have demonstrated an increasing prevalence of F necrophorum as the causative agent in acute mastoiditis in children, with associated high rates of intracranial complications such as epidural abscess and sinus venous thrombosis, to name a few. F necrophorum requires a treatment protocol that differs from the empiric treatment that is tailored to more common pathogens (eg, group A streptococci, Streptococcus pneumonia), and hence expediting the diagnosis is important. For evaluating complicated acute mastoiditis in children, cranial CT venography remains the imaging study of choice in most medical centers due to its availability in emergency situations. Based on our clinical experience, our hypothesis is that children with F necrophorum-associated complicated acute mastoiditis can be differentiated from those with other etiologies using CT venography.

MATERIALS AND METHODS

CT venography studies of 76 children hospitalized and treated for complicated acute mastoiditis were retrospectively reviewed. Retrieved imaging data included intracranial complications (epidural abscess, sinus venous thrombosis), cranial bone-related complications, and extracranial complications (subperiosteal abscess, temporomandibular joint abscess, and soft-tissue inflammation). The cohort was divided into children with F necrophorum-related disease (study group) and those with non-F necrophorum-related disease (control group).

RESULTS

Thirty-seven children (49%) comprised the study group, and 39 children in whom the causative agents were other bacteria comprised the control group. There were significantly higher rates of complications in the study group: sinus venous thrombosis (P < .001), perisigmoid epidural abscess (P = .036), and extramastoid osteomyelitis (P < .001). Thrombosis in venous sites beyond the sigmoid sinus and jugular foramen (a pattern consistent with an otogenic variant of Lemierre syndrome) and emphysematous osteomyelitis were found only among children in the F necrophorum-related study group (32% and 22% accordingly).

CONCLUSIONS

In children with complicated acute mastoiditis, CT venography findings of emphysematous osteomyelitis and/or thrombosis in venous sites beyond the sigmoid sinus and jugular foramen (a pattern consistent with the otogenic variant of Lemierre syndrome) should lead the radiologist to suggest F necrophorum-related mastoiditis.

Persistent foramen of Huschke: Clinical manifestations and complications, systematic review

BACKGROUND

Foramen of Huschke is a bone defect with wide clinical symptoms which ca can be responsible for severe complications. Clinical history and imaging are unspecific, it is therefore essential to recognize and treat the pathology related to the persistence of this foramen, to avoid destruction of the TMJ, chronic pain or OBJECTIVE: The aim of this review was to summarise the clinical manifestations and complications of persistent foramen of Huschke in adult patients, through a review of the cases reported in the literature.

METHODS & MATERIALS

A literature search of the PubMed, Cochrane Library, ScienceDirect and Embase databases was conducted for all articles published up to November 2022 to identify studies and case reports concerning clinical manifestations and complications of persistent foramen of Huschke in adult patients, with the key words "foramen of Huschke" or "foramen tympanicum".

RESULTS

74 papers where firstly identify, and 21 were selected. This correspond to 46 patients with the additional case from our department. Symptoms mostly reported consisted of otitis (63%, 29/46), otorrhea (28.26%, 13/46), and masticatory tinnitus (19.57%, 9/46). Diagnosis was priority made by CT-scan (95.65%, 44/46). Surgery was the most performed treatment (28.26%, 13/46). In our case, the use of FLUOBEAM® NIR camera was help-full for TMJ surgery.

CONCLUSION

Persistent foramen of Huschke should be suspected in the presence of otitis, otorrhea and masticatory tinnitus. Knowledge of this anatomical variation could help to treat certain pathology like TMJ disorders or TMJ septic arthritis.

Pediatric temporomandibular joint ankylosis and arthritis: Forgotten complications of acute otitis media

OBJECTIVES

Temporomandibular joint (TMJ) arthritis and ankylosis represent unusual but potential complications of ear suppuration, especially in children. We performed a review of the literature of pediatric otogenic TMJ arthritis and ankylosis, discussing their clinical and radiological features, their mechanism of infection spread, and the importance of a prompt diagnosis and treatment. We additionally describe a case of TMJ ankylosis following acute mastoiditis in a 4-year-old female patient.

METHODS

A search of English literature from January 1, 1980 to December 31, 2021 was performed on the electronic databases (PubMed, Web of Science and Scopus) in order to identify studies concerning TMJ complication after ear suppuration.

RESULTS

Seventeen articles were considered eligible for the review. Eight and nine studies described otogenic TMJ ankylosis and arthritis, respectively. A total of 17 children affected by ankylosis consequent to ear infection and a total of 31 cases of TMJ arthritis concurrent to otomastoiditis were identified. Mean time elapsed between ear infection and diagnosis of TMJ ankylosis was 4.8 years (range 0.5-13).

CONCLUSION

TMJ involvement during complicated otitis media should be kept in mind. Its prompt recognition is mandatory to set up appropriate treatment and follow-up and reduce the risk of ankylosis with its functional and psychological complications.

Pediatric temporomandibular joint (TMJ) arthritis, an elusive complication of acute mastoiditis

INTRODUCTION

Septic arthritis of the Temporomandibular joint (TMJ) is a rare complication of acute middle ear infection. Presentation is elusive and could be easily missed. Often diagnosis is made only with consequential development of TMJ ankylosis. This study intends to characterize patients and course of disease and suggest a diagnostic and therapeutic strategy.

METHODS

Retrospective review of all children diagnosed with TMJ arthritis and/or TMJ ankylosis secondary to acute middle ear infection, treated in a tertiary pediatric medical center between the years 2005 and 2021.

RESULT

Seven patients were identified with otogenic TMJ arthritis. Median age at presentation was 1.14 years (IQ range 1.1-1.5). All seven were diagnosed with acute mastoiditis. CT scans demonstrated TMJ related collections in 5/7 and intracranial complications in 3/7. Treatment included cortical mastoidectomy for 5/7. One patient had a concomitant surgical washout of the TMJ. Two patients had drainage only of subperiosteal collections. Six of the seven patients went on to develop TMJ ankylosis that presented within a median of 2.8 years (IQ range 2.6-3.9) after the episode of acute mastoiditis. All six patients presented with trismus and facial growth anomalies, and all but one required surgery to release the ankylosis.

CONCLUSION

Otogenic TMJ arthritis develops mostly in young children with acute mastoiditis and intratemproal and/or intracranial suppuration. Imaging is helpful in making the diagnosis, with TMJ related collections on CT being the most common finding. TMJ ankylosis can develop within a few years and present with trismus and abnormal facial growth. Cortical mastoidectomy does not seem to prevent ankylosis. It remains unclear whether focused treatment to the TMJ or physiotherapy could be beneficial in that.

Diagnosis, treatment and prognosis of otomastoiditis induced by Fusobacterium necrophorum: A retrospective multicentre cohort study

OBJECTIVES

Otomastoiditis caused by the anaerobic Fusobacterium necrophorum (F. necrophorum) often induces severe complications, such as meningitis and sinus thrombosis. Early diagnosis is difficult, partly because little is known about specific early signs. Comprehensive research about clinically chosen antimicrobial therapy has not been done yet and prognostic information about otomastoiditis caused by F. necrophorum is scarce. More knowledge about this subject is required.

METHODS

In this retrospective cohort study, we included all cases of otomastoiditis caused by F. necrophorum treated in two university medical centres in the Netherlands during the past 10 years. Data was gathered from patient records and analysed using independent sample T-tests and Chi²-tests.

RESULTS

This study reveals that otomastoiditis caused by F. necrophorum potentially induces neurological sequelae. Thereby, 80% of all included patients (n = 16) needed readmission within six months due to recurrence or complications of otomastoiditis caused by F. necrophorum. Mean (range) of age, CRP and temperature were 4.5 years (0.9-29.3), 243 mg/L (113-423) and 40 °C (37-41). All patients were hospitalized and treated with antibiotics, mostly metronidazole (n = 13/16) and a β -lactam (n = 15/16). Additional treatment contained low molecular weight heparin (83%, n = 10/12), dexamethasone (78%, n = 7/9) and/or surgery (80%, n = 12/16, whereof 9/12 mastoidectomy).

CONCLUSIONS

Patients and/or their parents need to be informed about this potential unfortunate prognosis when otomastoiditis caused by F. necrophorum is diagnosed. To improve early diagnosis, otomastoiditis caused by F. necrophorum should be suspected and therefore immediately cultured when a) young children present with otomastoiditis, with b) high CRP values, and/or c) vomiting and decreased consciousness.

"Multidisciplinary management of post- infective osteoarthritis and secondary condylar resorption of temporomandibular joint: a case report in a 9 years-old female patient and a review of literature"

Background

Osteoarthritis and condylar resorption of temporomandibular joint (TMJ) has rarely been reported in children as consequence of otologic disease. We describe the management of a case in a 9-year-old female as long-term complication of an otomastoiditis and review the literature currently available on this topic.

Case presentation

A nine-years-old female patient referred to Emergency Room of Bambino Gesù Children’s Research Hospital, IRCCS (Rome,Italy) for an acute pain in the left preauricular area and reduced mandibular movements. In the medical history an otomastoiditis and periorbital cellulitis was reported at the age of six with complete remission of symptoms after antibiotic treatment. No recent history of facial trauma and no previous orthodontic treatment were reported. She was referred to a pediatric dentist that conducted a clinical examination according to the Diagnostic Criteria of Temporomandibular Disorders (DC/TMD) and was diagnosed with bilateral myalgia of the masticatory muscles and arthralgia at the level of the left TMJ. Then, a complete diagnostic path was performed that included multidisciplinary examinations by a rheumatologist, infectious disease specialist, ear nose and throat (ENT) doctor, a maxillofacial surgeon and a medical imaging specialist. Differential diagnosis included juvenile idiopathic arthritis, idiopathic condylar resorption, trauma, degenerative joint disease, neurological disease. Finally, unilateral post-infective osteoarthritis of the left TMJ with resorption of mandibular condyle was diagnosed. The patient went through a pharmacological therapy with paracetamol associated to counselling, jaw exercises and occlusal bite plate. After 1 month, the patient showed significant reduction of orofacial pain and functional recovery that was confirmed also one-year post-treatment. The novelty of this clinical case lies in the accurate description of the multidisciplinary approach with clinical examination, the differential diagnosis process and the management of TMD with conservative treatment in a growing patient.

Conclusions

Septic arthritis of temporomandibular joint and condylar resorption were described as complications of acute otitis media and/or otomastoiditis in children. We evidenced the importance of long-term follow-up in children with acute media otitis or otomastoiditis due to the onset of TMJ diseases. Furthermore, in the multidisciplinary management of orofacial pain the role of pediatric dentist is crucial for the diagnostic and therapeutic pathway to avoid serious impairment of mandibular function.

Septic Arthritis of the Temporomandibular Joint with Intracranial Extension: A Case Report

Septic arthritis of the temporomandibular joint (TMJ) is rare with few cases reported in the literature. We present a case of septic arthritis of the left TMJ in an 18-year-old man who was initially referred as a suspected TMJ dislocation. He had a 3-day history of pain, trismus and malocclusion with left preauricular swelling and became clinically septic with a positive blood culture containing Fusobacterium necrophorum. Computed tomography revealed left TMJ effusion. A later scan showed evidence of a temporal space collection and development of an intracranial extension in the left middle cranial fossa. The patient underwent needle arthrocentesis and drainage, followed by six weeks of antibiotic therapy following advice from neurosurgery and microbiology. Further imaging revealed resolution of the collection. Few cases have been reported of this unusual diagnosis, and this case demonstrates the importance of close multidisciplinary input in forming an accurate diagnosis and managing appropriately.

Otogenic temporomandibular septic arthritis in a child: a case report and a review of the literature

Background

Acute otitis media is one of the most common infectious diseases in the paediatric age and although its complications such as acute mastoiditis have become rare thanks to improvements in therapeutic approaches, possible serious complications such as septic arthritis of the temporomandibular joint may develop. A prompt diagnosis and adequate treatment are essential to achieving the best outcome and avoiding serious sequelae. We describe a case occurring in a previously healthy 6-year-old female and review the literature currently available on this topic.

Case presentation

The patient presented a right temporomandibular septic arthritis with initial mandibular bone involvement secondary to acute otitis media. She presented with torcicollis, trismus, right preauricular swelling over the temporomandibular joint and was successfully treated with antibiotic treatment alone.

Conclusions

Septic arthritis of the temporomandibular joint is a rare complication of acute otitis media or acute mastoiditis in children. It should be suspected in patients presenting with trismus, preauricular swelling or fever. No guidelines on the diagnosis and treatment of this infectious disease are currently available.

Ankylosis of the Temporomandibular Joint in Pediatric Patients

INTRODUCTION

While surgical interventions for temporomandibular joint (TMJ) ankylosis are well-documented, there is lack of consensus regarding the ideal approach in pediatric patients. Surgical interventions include gap arthroplasty, interpositional arthroplasty, or total joint reconstruction.

METHODS

A systematic review of PubMed (Jan 1, 1990-Jan 1, 2017) and Scopus (Jan 1, 1990-Jan 1, 2017) was performed and included studies in English with at least one patient under the age of 18 diagnosed with TMJ ankylosis who underwent surgical correction. Primary outcomes of interest included surgical modality, preoperative maximum interincisal opening (MIO) (MIOpreop), postoperative MIO (MIOpostop), ΔMIO (ΔMIO = MIOpostop - MIOpreop), and complications.

RESULTS

Twenty-four case series/reports with 176 patients and 227 joints were included. By independent sample t tests MIOpostop (mm) was greater for gap arthroplasty (30.18) compared to reconstruction (27.47) (t = 4.9, P = 0.043), interpositional arthroplasty (32.87) compared to reconstruction (t = 3.25, P = 0.002), but not for gap compared to interpositional (t = -1.9, P = 0.054). ΔMIO (mm) was greater for gap arthroplasty (28.67) compared to reconstruction (22.24) (t = 4.2, P = 0.001), interpositional arthroplasty (28.33) compared to reconstruction (t = 3.27, P = 0.002), but not for interpositional compared to gap (t = 0.29, P = 0.33). Weighted-average follow-up time was 28.37 months (N = 164). 4 of 176 (2.27%) patients reported development of re-ankylosis. There was no significant difference in occurrence of re-ankylosis between interventions.

CONCLUSIONS

Given the technical ease of gap arthroplasty and nonsignificant differences in ΔMIO, MIOpostop, or occurrence of re-ankylosis between gap and interpositional arthroplasty, gap arthroplasty should be considered for primary ankylosis repair in pediatric patients, with emphasis on postoperative physiotherapy to prevent recurrent-ankylosis.
