Aim: To determine the presentation and predisposing factors for paediatric deep neck space infection. Methods: A prospective observational study was conducted in the Department of ENT, Anugrah Narayan Magadh Medical College and Hospital, Gaya, Bihar, India, for 11 months. 100 Children from 0 to 12 years of age were studied. Diagnosis was made by ultrasonography and computed tomography scan (in some cases). Pus culture was done to know the causative organisms in cases presenting with abscesses. Ultrasonography of neck and Radiological investigations (x-ray soft tissue neck and CT Scan) were done to determine the location and extent of the abscesses. All patients were started on empirical antibiotic therapy of amoxicillin and clavulanic acid and metronidazole. Results: 65% of the patients were male and 35% were female. Most of the patients were in the age group of 6-9 years. The most common symptom was neck swelling (83%) followed by pain in the neck (71%), fever (68%), and sore throat (44%). The most common clinical finding was swelling in the neck (90%) followed by oropharyngeal swelling (22%), dental abnormality (11%), trismus (9%). The source of infection was unknown in about 58 patients (58%) while others had history of upper respiratory tract infection in about 12 patients (12%) and dental infections in 10 (10%) patients. Cervical lymphadenopathy was noted in 3 (3%) patients. 10 (10%) patients presented with complications. The most common complication was upper airway obstruction, which was seen in 8 patients followed by mediastinitis in 1 patient and sepsis in 1 patient. Conclusion: we concluded that the Deep neck space infections (DNSI) in paediatric population constitute a medical emergency as it could lead to life threatening complications in a short time.
