• Resumen

  • Introduction: Oroantral fistulae are communications between the oral cavity and the maxillary sinus, primarily caused by tooth extractions. The majority of these communications close spontaneously due to their small size, but others form fistulae, perpetuating this pathological situation until proper treatment is provided, causing both local and general pathology.

    Case report: We present the case of a 49-year-old male without previous medical history who wasreferred to the Oral Surgery Department at Hospital Virgen de La Paloma presenting with a three-week history of oroantral fistula with acute sinusitis of the left maxillary sinus. After evaluation of the varioustherapeutic options, Bichat’s buccal fat pad pedicle flap was performed along with a vestibular advancement flap, in a double-layer closure technique.

    Conclusions: There are multiple techniques described in the literature for correcting this pathological entity, each with their own advantages and disadvantages. It is necessary to know the details of each of them in order to establish the ideal treatment for each situation.
