Neglected peritonsillar abscess resulting in necrotizing soft tissue infection of the neck and chest wall

Synchronous cervical necrotizing fasciitis and pharyngocutaneous fistula: A case report

Introduction and importance

Necrotizing fasciitis is a fulminant infection that spreads along the fascial planes. It is a rare entity with potentially fatal outcomes. The head and neck involvement is infrequent, with primary source either odontogenic or pharyngeal infection by single or mixed bacterial flora. To our knowledge, synchronous cervical necrotizing fasciitis (CNF) and pharyngocutaneous fistula is rarely reported in pieces of literature.

Case presentation

We present a 38-years-old female patient who presented with CNF and pharyngocutaneous fistula. Diabetes mellitus was accidentally discovered during the investigation. The patient was successfully treated with broad-spectrum antibiotics, serial surgical debridement sessions, wound irrigation, and multiple muscular and myocutaneous skin flaps.

Clinical discussion

Rapid diagnosis, radical surgical debridement of all necrotic tissue, intravenous broad-spectrum antibiotics, and close monitoring of patients with CNF are crucial to avoid critical complications and better patient survival. Due to the poor healing process in the neck area, the pharyngocutaneous fistula should be repaired with good musculocutaneous flaps such as the pectoralis major myocutaneous flap. Meticulous suturing of the flap to the mucosa, reinforcement of the repair with muscle, and suturing of the skin without tension are essential to obtaining a successful outcome.

Conclusion

Synchronous CNF and pharyngocutaneous fistula are rare events. Initial diagnosis and serial surgical debridement, along with aggressive broad-spectrum antibiotics and adequate resuscitation with great attention to the poor healing process in the diabetic patients' neck area, are critical for a beneficial result. In our case, the reconstruction was performed successfully using multiple muscular and skin flaps.

•

Cervical necrotizing fasciitis (CNF) is a fetal infection with a high mortality rate even under ideal medical conditions.

•

Synchronous CNF and pharyngocutaneous fistula are rare occurrence.

•

In CNF with pharyngocutaneous fistula, initial diagnosis, surgical debridement, broad-spectrum antibiotics and resuscitation with attention to poor healing process, are critical for a beneficial result.

Complications of peritonsillar abscess

Background

The vast majority of patients with peritonsillar abscess (PTA) recover uneventfully on abscess drainage and antibiotic therapy. However, occasionally patient´s condition deteriorates as the infection spread in the upper airway mucosa, through cervical tissues, or hematogenously. The bacterial etiology of PTA is unclarified and the preferred antimicrobial regimen remains controversial. The current narrative review was carried out with an aim to (1) describe the spectrum of complications previously recognized in patients with peritonsillar abscess (PTA), (2) describe the bacterial findings in PTA-associated complications, and (3) describe the time relation between PTA and complications.

Methods

Systematic searches in the Medline and EMBASE databases were conducted and data on cases with PTA and one or more complications were elicited.

Results

Seventeen different complications of PTA were reported. The most frequently described complications were descending mediastinitis (n = 113), para- and retropharyngeal abscess (n = 96), necrotizing fasciitis (n = 38), and Lemierre´s syndrome (n = 35). Males constituted 70% of cases and 49% of patients were > 40 years of age. The overall mortality rate was 10%. The most prevalent bacteria were viridans group streptococci (n = 41, 25%), beta-hemolytic streptococci (n = 32, 20%), F. necrophorum (n = 21, 13%), S. aureus (n = 18, 11%), Prevotella species (n = 17, 10%), and Bacteroides species (n = 14, 9%). Simultaneous diagnosis of PTA and complication was more common (59%) than development of complication after PTA treatment (36%) or recognition of complication prior to PTA (6%).

Conclusion

Clinicians involved in the management of PTA patients should be aware of the wide range of complications, which may arise in association with PTA development. Especially males and patients  > 40 years of age seem to be at an increased risk of complicated disease. In addition to Group A streptococci and F. necrophorum, the current findings suggest that viridans group streptococci, S. aureus, Prevotella, and Bacteroides may also play occasional roles in the development of PTA as well as spread of infection. Complications occasionally develop in PTA patients, who are treated with antibiotics and surgical drainage.

Cervical necrotizing fasciitis as a complication of acute epiglottitis managed with minimally aggressive surgical intervention: Case report

Cervical necrotizing fasciitis secondary to epiglottitis is rare. The standard treatment of this severe condition has long been early and aggressive surgical debridement and adequate antimicrobial therapy. We report the case of an immunocompetent 59-year-old man who developed cervical necrotizing fasciitis as a complication of acute epiglottitis. We were able to successfully manage this patient with conservative surgical treatment (incision and drainage, in addition to antibiotic therapy) that did not involve aggressive debridement.

[Necrotizing fasciitis due to a peritonsillar abscess]

BACKGROUND

Necrotizing fasciitis is a potentially life-threatening complication of severe cervical soft tissue inflammation. The characteristic feature is the rapid spread of the infection, which descends and potentially leads to mediastinitis and sepsis.

METHODS

Within a year, 4 patients with peritonsillar abscess (PTA) and necrotizing fasciitis were treated at Dessau Medical Center. Therapy consisted of abscess tonsillectomy, immediate surgical debridement, extensive wound drainage, early tracheostomy, and systemic antibiotics.

RESULTS

Symptoms decreased after intensive care and surgical removal. All patients were discharged after wound healing. The death of the oldest, multimorbid patient several weeks later was ascribed to the accompanying diseases.

CONCLUSION

Early diagnosis, aggressive surgical debridement in association with tracheostomy and intravenous antibiotic therapy may reduce mortality significantly.

Cervical necrotising fasciitis and descending mediastinitis secondary to unilateral tonsillitis: a case report

Introduction

Cervical necrotizing fasciitis is an aggressive infection with high morbidity and mortality. We present a case of cervical necrotizing fasciitis and descending mediastinitis in a healthy young man, caused by unilateral tonsillitis with a successful outcome without aggressive debridement.

Case presentation

A 41-year-old man was admitted to our unit with a diagnosis of severe acute unilateral tonsillitis. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. Computed tomography scan of his neck and chest showed evidence of cervical necrotizing fasciitis and descending mediastinitis secondary to underlying pharyngeal disease. He was treated with broad-spectrum intravenous antibiotics. His condition improved over the next 3 days but a tender and fluctuant swelling appeared in the suprasternal region. A repeat scan showed the appearance of an abscess extending from the pretracheal region to the upper mediastinum which was drained through a small transverse anterior neck incision. After surgery, the patient's condition quickly improved and he was discharged on the 18th day of admission.

Conclusion

Less invasive surgical techniques may replace conventional aggressive debridement as the treatment of choice for cervical necrotizing fasciitis and descending necrotizing mediastinitis.

Necrotizing fasciitis of the chest wall with a retropharyngeal abscess: case report and literature review

We herein report a case of a diabetic 49-year-old woman with anterior chest wall necrotizing fasciitis that caused a retropharyngeal abscess and discuss the literature surrounding necrotizing soft tissue infections of the chest wall. The patient was treated with serial wound debridements, antibiotic therapy, and percutaneous drainage and serial irrigation of the retropharyngeal abscess with a silicone catheter. The resulting defect was grafted with a split thickness skin graft.
