The authors report their experience with temporomandibular joint (TMJ) traumas involving breakage of the roof of the glenoid cavity, an infrequent event that occurs in those cases in which, as a result of the condylar neck not fracturing, the traumatic energy is transmitted to the middle skull base. As the literature contains no valid series for establishing standardized protocols for the treatment of these fractures, we propose our own orthopedic-functional approach. The patient observed by us had suffered a cranio-facial trauma and presented the classical symptoms and signs of TMJ traumas and complete bilateral Bell paralysis. He was subjected to a CAT scan and then to 2-stage treatment consisting of functional rest with liquid diet followed by physiotherapy. An almost total recovery in TMJ function was observed after 1 month. At 1-year follow-up the facial paralysis had resolved completely. On the basis of our experience, breakages of the glenoid cavity can be compared, in terms of treatment procedure, to intracapsular fractures of the TMJ with surgery confined to cases of ankylosis sequelae. To avoid the onset of ankylosis careful control of clinical, functional and radiological follow-up is required.
