Failure factors in pediatric deep neck space abscess surgical management

Deep neck space infections (DNSI) in pediatric otolaryngology are a common occurrence in the inpatient setting. A subset of DNSI patients will fail medical and surgical management. It is difficult to predict which patients will fail. There are no studies that effectively evaluate variables associated with readmission and reoperation for DNSI abscesses. The purpose of this study was to evaluate the specific perioperative decisions that may lead to combined therapy failure and necessitate reoperation.

A case-control study was performed at a single center academic tertiary care hospital. Patients <18 years old treated from January 2015 to April 2020 with a surgically treated DNSI were reviewed. The single incision and drainage group (SOp) and reoperation group (ReOp) were evaluated with reoperation performed within a 30-day period. Intravenous antibiotic administration timing, drain management and type (gauze or latex), diagnostic, and postoperative factors were evaluated.

The SOp group consisted of 275 patients and the ReOp group of 21 patients. The average preoperative intravenous antibiotic time showed no statistical difference (p = 0.884) and no increased risk for reoperation (p = 0.470; OR = 0.993). Timing of drain removal showed a significant difference (p < 0.005; 41.1 SOp vs 46.5 h ReOp). Abscess location (p = 0.855) and complications rate did not vary (p = 0.450). Gauze drains were used in 131 (44.3%), latex in 80 (27%), and no drain in 84 (28.4%) with no difference regarding reoperation (p = 0.124). Length of stay was longer in the ReOp group (8 vs 4 days; p < 0.001). The average measured dimension for each group did not significantly vary (p = 0.633).

The duration of antibiotics in the preoperative period showed no statistical role in the need for reoperation in DNSI abscess patients. Drain type and duration also had a potentially clinically relevant association with the need for reoperation. Extensive unknown abscess pockets or inadequate technique may be the main contributors to the need for reoperation.
