Necrotizing fasciitis (NF) is rare but life threatening multimicrobial soft tissue infection characterized by progressive, usually rapid, necrotizing process of the subcutaneous tissues and fascial planes, with resulting skin gangrene and systemic toxicity. The groin, abdomen and extremities are the most frequent sites involved by this disease and it is rarely seen in the head and neck region. NF of the head and neck region has a potentially high morbidity and mortality. Delay in diagnosis leads to poor outcome. Hence early recognition and aggressive management is imperative for successful outcome. Here we present a case of acute onset of cervical necrotizing fasciitis in a young male.Keyword Necrotizing fasciitis Á Soft tissue infections Á Diabetes mellitus
Case ReportA 33-year old male presented to the emergency room complaining of painful neck swelling with difficulty in breathing. Patient was apparently alright the previous night and noticed the swelling during the early morning hours. The cervical swelling increased over the next few hours and was brought to the hospital by noon. Patient did not have any associated history of throat pain, trauma, or tooth ache. He was a normotensive and not a diabetic, had family history of diabetes. Examination showed a diffuse swelling of submental and submandibular region with edema of the floor of the mouth with trismus. The skin over the swelling was erythematous, tender and the swelling was fluctuant. Provisionally a diagnosis of Ludwig's angina with submandibular abscess was made. Patient had difficulty in breathing on lying down. A X-ray neck lateral view done else where showed evidence of airway obstruction (Fig. 1). Patient was shifted for CT scan and developed stridor on table. Hence he was immediately rushed to the theatre and an emergency tracheostomy was done. A low tracheostomy was done as none of the landmarks in the neck could be identified (Fig. 2).It was decided to explore the neck on table. A transverse incision was made over the submental region. The whole subcutaneous fat and partly the muscles were found to be necrosed (Fig. 3) and it was foul smelling. A brownish fluid oozed out of the muscle planes and there was no evidence of pus in the submental or submandibular space. Deep cervical fascia was found to be necrosed and the debrided tissues were sent for histopathological examination. Similarly the parapharyngeal spaces were explored on either sides through a separate vertical incision along the sternocleiodomastoid to look for any abscess formation. Necrosed subcutaneous fat from these areas were debrided and a swab was sent for culture sensitivity from these necrosed areas. A dental examination was also done in the same sitting to look for any dental foci. However the oral cavity and oropharynx were normal except for edematous floor of the mouth. The explored areas were left open and antibiotic dressings applied. Blood report showed leukocytosis. His random sugar levels were 350 mg/dl. Glycosylated haemoglobin was 9.5. Patient was started...
