Drenaje percutáneo ecoguiado vs. drenaje quirúrgico en abscesos cervicales profundos de origen odontógeno. Ensayo clínico controlado y aleatorizado

Abstract

IntroductionThe most common cause of deep neck infections is dental infection. They are diagnosed with physical examination, imaging studies, ultrasound, or computed tomography. Surgical drainage of collections should always be performed early in a classical or percutaneous way, depending on the case. The aim of the study was to compare ultrasound-guided percutaneous drainage techniques vs. surgical drainage in deep cervical abscesses of odontogenic origin in a controlled and randomized trial. MethodsA randomized controlled clinical trial was performed from January 2015 to December 2019. Hospital stay was evaluated as an efficiency variable. Epidemiological and secondary variable data (tumour, trismus, fever, pain), leukocytosis, cosmetic result comparing both techniques were analysed. Statistical analysis was carried out with STATA v 14.0. Results128 patients were analysed, 51 women and 77 men. Average age 27.3 (SD = 10.13). The percutaneous group had a mean hospital stay of 3.03 (SD = 2.86) days and the surgical group 5.46 (SD = 2.96). The p-value was <.001. Cosmetic results showed differences favouring the percutaneous drainage group. None of the other variables showed statistically significant results. DiscussionSurgical treatment (cervicotomy and debridement) should be undertaken early with evidence of extensive collection in deep spaces. Minimally invasive image-guided procedures are an alternative. These can be performed in well-located, unilocular collections, without compromising of the patient's airway. Percutaneous drainage and suction techniques if necessary, serially, or drainage placement may be performed. ConclusionsUltrasound-guided and serially guided percutaneous drainage is the best therapeutic option in patients with mild and/or moderate dental infections.
