Reconstrucción de defectos parotídeos con injertos de tejido graso libre abdominal. Estudio clínico de una sencilla técnica quirúrgica

Abstract

Introduction: Parotid surgery is a common technique with multiple approaches and reconstruction options. Primary reconstruction options are the superficial musculoaponeurotic system (SMAS) flap, the sternocleidomastoid muscle flap, free or microvascular grafts and biomaterials (Alloderm), among others. We present our experience in periumbilical abdominal free fat graft for primary reconstruction of the parotid defect. Material and methods: A observational study was performed in patients requiring a parotidectomy (superficial, total or radical) due to a primary parotid neoplasm or tumor recurrence. In all cases were used a free abdominal fat graft. The patients were operated by the same surgeon between May 2013 and January 2019. The study analyzes epidemiological and clinical aspects, approach, surgical time, hospital stay, post-surgical complications, sequelae, clinical follow-up and aesthetic results. Results: A total of 22 patients were incluyed after a conservative, total or radical superficial parotidectomy. Thirteen men and nine women aged between 13 and 79 years (46 years on average), with the initial diagnosis made by fine water aspiration puncture (FNA) and Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI). Aesthetic result in all patients was excellent or very good. No long-term sequelae or syndromes Frey. No complications interest except minor postsurgical hematomas and seroma. Conclusion: A very simple technique with few complications is presented for the primary reconstruction of postparotidectomy defects with excellent aesthetic results.
