Abstract
Management of an infratemporal fossa abscess (IFA), which is a specific form of severe and advanced deep fascial space infection (DFI), is based mainly on traditional methods. The purpose of this study was to investigate the role of mandibular coronoidectomy in accelerating IFA healing. This research is a single-center retrospective study composed of 23 patients with IFA. The predictor variables were gender, age, diabetes, severity score, and mandibular coronoidectomy. The outcome variables included hospitalization time (HT) and irrigating time (IT). A comparison of treatment outcomes between the improved and traditional surgical interventions for IFA was performed. Compared with patients who did not receive mandibular coronoidectomy (NC group; HT, 17.54±1.80days; IT, 38.54±3.73days), patients who underwent mandibular coronoidectomy (AC group) had significantly decreased HT (7.20±1.19days) and IT (15.10±1.27days; P<.01). In addition, 4 patients (31%) in the NC group received reoperation for osteomyelitis, whereas no osteomyelitis and DFI recurrence occurred in the AC group. Mandibular coronoidectomy with extra intraoral drainage could considerably accelerate the healing process of IFAs and obviously decrease the reoperation rate for osteomyelitis.
