Queratoquiste odontogénico mandibular. Presentación como trismus de larga evolución

Abstract

The patient underwent surgery with general anesthesia to resect the lesion. An intraoral approach via a crest incision was used. Teeth 37 and 38 were extracted and the cyst in the area of the mandibular body and condyle was resected and fixed with Carnoy solution. The lingual nerve included in the tumoral tissue was sectioned and resutured. Two specimens were obtained in the intervention and studied histologically. The first specimen of adjacent soft tissue showed no tumoral infiltration. The second specimen was identified as a keratocyst with granulomatous reaction to keratin. Postoperative follow-up orthopantomography showed that the cyst had been eliminated and mandibular fractures were absent (Fig. 3).The patient's trismus improved during hospitalization and up until the intervention. Throughout the hospital admission, the patient was fed enterally by nasogastric tube. She had mild trismus and adequate tolerance of feeding at discharge. Follow-up with regular outpatient visits disclosed a favorable evolution without recurrence. © 2008 ergon.
