Introduction: Deep neck infections (DNIs) are abscesses located in the profound spaces of the neck and constitute one of the most common otolaryngological life-threatening emergencies. The aim of this study is to review the clinical and demographic data of patients with DNI and identify factors associated with prolonged hospitalization, reoperation, and mortality.
Methods: Retrospective review and analysis of 75 patients with DNI admitted from January 2015 to Decem ber 2019 in a tertiary referral hospital.
Results: Of 75 patients, 50 (66.6%) were males and 25 (33.3%) females. Age ranged from 18 to 91 years with a mean of 41.79 (±15.48). DNIs were odontogenic in 49 patients (65.3%). History of diabetes mellitus (DM) was positive in 26 patients (34.6%). The submandibular space was involved in 57 patients (76%).
Streptococcus spp. were isolated in 35 patients (46%). Intubation for airway preservation was needed in 21 patients (28%) and tracheostomy in 6 (8%). Mediastinitis presented in 8 patients (10.67%), with a mortality rate of 62.5% (
n = 5). Mean hospital stay was 9.13 days (±7.2). DM (
p = 0.016), age (
p = 0.001), BMI classification 3, 4, and 6 (
p = 0.041), and intensive care unit (ICU) admission (
p = 0.009) were associated with a longer stay. Surgical drainage was performed after 1.71 days (±1.65). Surgical reintervention was needed in 6 cases (8%) and was associated with temporal (< i>p = 0.001) and masticator (
p = 0.002) space involvement and DM (
p = 0.009). Overall mortality was 8% and decreased to 1.5% when mediastinitis was excluded. Mediastinitis (
p = 0.001), ICU admission (
p #x3c; 0.0001),
Streptococcus spp. (
p = 0.019), and low hemoglobin levels (
p = 0.004) were associated with mortality.
Discussion/Conclusion: DNIs are entities associated with high morbimortality. Mediastinitis and airway obstruction are life-threatening possible complications and should be promptly evaluated. Low HB could be used as a predicting factor for mortality.
