Intra-oral Drainage of Submandibular Abscess: A Minimally Invasive Technique. A Prospective Study.

ABSTRACT

PURPOSE: To evaluate the efficacy of intraoral drainage of isolated submandibular space abscess as a minimally invasive surgical technique compared to the standard trans-cervical approach. PATIENTS AND METHODS: This prospective study included 40 subjects with isolated submandibular space abscesses. They were randomly divided into 2 equal groups trans-cervical surgical drainage (group A) and intra-oral surgical drainage (group B). The included data were demographics, repeated surgery requirement, postsurgical hospitalization duration, formation of scar, and complications. RESULTS: Intraoral drainage (Group B) reduced the mean operative time by 15.25 min (P < 0.001) compared with trans-cervical incision (Group A). No considerable difference was found between the 2 groups in regarding hospitalization postoperatively. No weakness in marginal mandibular nerve was found in both groups. Three patients only have a cervical scar in a group (B) who required external drainage due to recollection. No recurrence was detected in a group (A). CONCLUSION: The current study demonstrated that isolated submandibular abscesses can be successfully managed with an intraoral drainage modality, and it is a better option than the trans-cervical approach regarding better cosmetic outcome and shorter operative time.
