Previously asepsis and antisepsis of facial region had been executed with povidone-iodine, Pharyngeal blockage and sterile drapes were placed. Xylocaine with 2% epinephrine was administered at the level of the left infra-orbital nerve. With scalpel blade number 15, a semi-lunar incision was made in apical location with respect to teeth 22, 63, 24, 25. Periosteum was removed and a muco-perisoteal flap was raised which revealed an non-perforated wall of the maxillary sinus anterior wall. Thinning of the vestibular cortical zone was observed, therefore, ostectomies were performed in order to expose the tumor Figure 4. Upon palpation, the tumor was firm, immovable and well circumscribed, it took up the whole maxillary sinus. With blunt dissection, full enucleation was completed. The upper left canine was found within the tumor.
Mediante anestesia general inhalatoria balanceada, con intubación oro traqueal, previa asepsia y antisepsia de la región facial con yodopovidona, previa colocación de taponamiento faríngeo y campos estériles, se infiltra xilocaína con epinefrina al 2% a nivel de nervio infraorbitario izquierdo, se realiza incisión semilunar, apical a los dientes 22, 63, 24, 25 con hoja de bisturí 15, se desperiostiza, obteniéndose colgajo mucoperióstico observándose pared anterior de seno maxilar sin perforación, sólo adelgazamiento de la cortical vestibular, por lo que se realiza ostectomías para exponerse la tumoración Figura 4; el cual se palpa de consistencia firme, no desplazable, bien delimitada, ocupando el seno maxilar en su totalidad; realizándose mediante disección roma la enucleación completa, observándose en el interior de la tumoración el canino superior izquierdo.
