Desplazamiento accidental del tercer molar al seno maxilarprotocolo de actuación

Zusammenfassung

Introduction: Accidental displacement of the third molar into the maxillary sinus is one of the complications of oral surgery. These extractions are usually complex due to some factors such as low visibility, limited space and the location of the tooth; so special care on these treatments is required. Objective: To establish an action protocol based on a surgical as well as a pharmacological treatment, and the monitoring that this kind of complications need according to the literature. Clinical case: A 17-year old man, with a noncontributory medical history, was referred to our clinic by a colleague to evaluate and perform a surgical extraction of his upper left third molar, which had been displaced into the maxillary sinus after a failed extraction, and was generating symptoms of acute sinusitis. The radiographic examination dismissed the affectation of the rest of the paranasal sinuses and confirmed the almost totally blockage of the left maxillary sinus. The extraction of this third molar took place by means of an anterior-wall ostectomy of the sinus; afterwards a pharmacological treatment was prescribed and regular control visits along the first year were planned. Discusion: The suggested treatment for this kind of complications involves the immediate recuperation of the tooth or its later extraction meanwhile the fibrosis forms around the displaced tooth, as needed. We have to take into account the infection, the limited mandibular range of movement as well as the patient´s psychological discomfort. The medical and pharmacological treatment should be prescribed following the reviewed literature, in order to obtain the sinusal drainage and the infection control. Conclusion: It is convenient to carry out an exhaustive radiological examination in case of close relation between the maxillary third molar and the maxillary sinus as well as evaluate its position and inclination to avoid this kind of complications.
