The Factors Contributing to Efficiency in Surgical Management of Purulent Infections of Deep Neck Spaces.

Deep neck infections (DNIs) are still emergency conditions in otorhinolaryngology. Due to rapid disease progression and life-threatening complications, the accurate surgical and medical treatment must be promptly applied. In the present study, we analyzed treatment protocols of 46 adults to assess efficacy of the treatment and search for prognostic factors of the outcomes. We performed retrospective analysis of medical data of 46 patients, who underwent surgical treatment in our department due to purulent DNI in the period from 2009 to 2017. Data investigated included age, sex, hospitalization time, duration of symptoms before drainage, comorbidities, selected laboratory tests results, location and the number of abscesses, results of microbiological cultures, and antibiotic treatment options. The study group consisted of 33 (71.7%) men and 13 (28.3%) women. Patients age ranged from 18 to 82 years. The mean duration of hospital stay was 13.2 ± 8.4 days. The most common site involved was submandibular space (43.5%), followed by parapharyngeal space (28.3%). The majority of patients had single abscess (81.2%), the multiple abscesses were revealed in 8 (18.8%) cases. The mean size of the abscesses was 42 mm. C-reactive protein level was increased in 96.7% patients (mean level 155.5  ±  146.7  mg/L), but the white blood cell count exceeded the normal in 60.9% cases (mean level 16.89  ±  5.59   ×  109/L). Staphylococcus aureus (20.7%) and Peptostreptococcus (20.7%) were the most common species cultured from swabs. The antibiotic treatment included most commonly a combined ceftriaxone and metronidazole (n = 23). Two patients died due to complications. The correlation between different variables and the duration of hospitalization revealed only the hemoglobin level below 12.5 g/dL, a significant predictor of longer hospitalization (16.23 days vs 12.09 days, P = .017). Patients with purulent DNIs and decreased hemoglobin level are predisposed to prolonged recovery following the surgical drainage.
