Deep neck space infections: an upward trend and changing characteristics.

PURPOSE: This study reviews our experience with deep neck space infections (DNIs) requiring surgical intervention, including cervical necrotizing fasciitis. The aim of the study was to identify predisposing and aggravating factors of the disease and recognize the possible factors that can lead to life-threatening complications and slow down the healing process. METHODS: We compare the results to previous data from 1985 to 2005 to find possible alterations and changing trends. The characteristics of four lethal cases are described. This retrospective analysis includes patient data from 2004 to 2015 in tertiary referral hospital and in total, 277 patients were found. RESULTS: Surgical drainage through a neck opening ± intraoral incision was made in 215 (77.6%) patients, an intraoral incision was only made in 62 patients (22.4%). ICU care was needed in 66 (23.8%) cases. Odontogenic etiology (44.8%) was the most common origin. The most common comorbidity was a psychiatric disorder and/or dementia and occurred in 55 (19.9%) patients. Patients with underlying illnesses were more likely to be admitted to the ICU (p = 0.020), required a longer ICU stay (p = 0.004) and repeated surgery (p = 0.009). Gas formation seemed to be predictive of a more severe course of infection. Early extraction of the odontogenic foci was related to a lower length of stay (LOS) (p = 0.039). CONCLUSION: The annual numbers have risen from 14 to 24 cases per year when compared to previous data. DNIs remain a cause of lethal complications; the mortality was 1.4% and overall complications occurred in 61 (22.0%) patients.

Early surgical intervention enhances recovery of severe pediatric deep neck infection patients.

PURPOSE: Pediatric deep neck space infection (DNI) is a relatively rare but potentially life-threatening condition and requires prompt and accurate management. This study retrospectively reviews our experience in a tertiary referral hospital from 2004 to 2019. METHODS: Systematic data collection from medical records using ICD10 codes between 2004 and 2019. INCLUSION CRITERIA: age ≤16 years, DNI requiring hospitalization and/or surgery. EXCLUSION: peritonsillar abscess without complications. RESULTS: We identified 42 patients, 21 boys and 21 girls, with a median age of 4.9 years. Most of the patients had severe symptoms, the most common of which were neck swelling (n = 39; 92.9%), neck pain (n = 39; 92.9%) and fever (n = 32; 76.2%). Twenty-two (52.4%) had torticollis, and the mean duration of symptoms before hospitalization was 4.95 days. Diagnosis was confirmed by MRI (n = 24), contrast-enhanced CT (n = 11) or ultrasonography (n = 6), except in one case. Twenty-three (54.8%) required an open neck incision, ten (23.8%) patients had intraoral surgery and nine were treated conservatively. Twelve (28.6%) patients were admitted to the pediatric ICU. Median hospitalization duration was six days. The infection most commonly had tonsillopharyngeal etiology (n = 18) and a retropharyngeal location (n = 17). Staphylococcus Aureus (n = 7) and Streptococcus pyogenes (n = 7) were the most frequent pathogens. We compared the early surgical intervention group (<2 days of intravenous antibiotics; n = 18; 42.9%) to the late surgery group (n = 15; 35.7%) and the conservatively treated groups (n = 9; 21.4%). The overall length of stay (LOS) was lower in the shorter preoperative medication group (mean 4.4 vs. 7.2; p = 0.009). The size of the abscess did not differ between the groups (mean 28 mm; 30 mm; 21 mm; p = 0.075) and the neck incision rate was similar in the operated groups. CONCLUSION: Early surgical intervention is associated with decreased LOS among severe pediatric DNI patients.
