case report _ CBCT in diagnosis I orrhages or anatomical variance. The doctors who hadbeenconsultedbeforeincludedageneralmedical practitioner, otolaryngologist, maxillofacial surgeon and neurosurgeon. The patient’s symptoms included pain in the neck, cheeks, temporomandibular joint and upper back, as wellastinnitusandhearingloss,andconstantvertigo, worsened with changing posture, while walking or with head movement. Another symptom reported was sporadicnausea.Shehadbeentreatedwithanalgesics, anti-inflammatories, muscle relaxants and ear irriga- tion.Unfortunately,therewasnofavourableprogress. Takingintoconsiderationthesymptomsdescribed, we obtained a CBCT scan, as well as CT images and 3-D reconstructions. The length of the structures was evidentevenwithoutmeasuring.Inordertodetermine the exact size, we took measurements of both styloid processes, and found a length of 51.32mm for the right styloid process and 48.35mm for the left. Once the exact size of the structures had been established, based on the severity of the symptoms and consultation with the maxillofacial surgeon, we decided to proceed to surgical resection. For this, we produced stereolithographic models to verify not onlythesize,butalsotheshapeanddirectionofboth styloid processes. Owing to the size and location of the styloid processes and taking into consideration the surrounding structures at risk, the group of sur- geons decided to perform the surgery extra-orally. A second CT was taken to evaluate the results. After having part of the styloid process removed, the patient began a favourable recovery. A month after the surgery, the symptoms had resolved almost completely._ Editorial note: A list of references is available from the publisher.
