RESUMEN
INTRODUCTION: Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. A number of interpositional materials have been used including alloplastic materials (acrylic, proplast-teflon, silastic), and autogenous tissues (temporalis muscle flaps, buccal fat pad, dermis, costochondral grafts, metatarsal, fibula, tibia, iliac crest, cranial bone and Sternoclavicular graft SCG and cartilage). Literature suggests that rather than growth centre, we need adaptive centre. SCG is presumed to be a more suitable material for interpositional arthroplasty because Sternoclavicular Joint (SCJ) and TMJ are very similar developmentally, histologically and morphologically throughout the growth period. MATERIAL AND METHOD: Patients with TMJ ankylosis (8 males, 2 females) underwent release of the ankylosed joint by the senior author, between June 2013 and Novemeber 2015. The age of the patients ranged from 10 to 19 years. Pre- and post- operative assessment included a thorough history and physical examination to determine the cause of ankylosis, the maximal incisal opening, etiology and type of the ankylosis, recurrence rate. RESULT: MIO at 6 months follow up was 37.4±2.633 mm (range 32-40 mm), greater than MIO achieved in immediate postoperatively {34.4±2.22 mm (range 30-38 mm). After reconstruction of temporomandibular joint with sternoclavicular graft in the growing child there was a significant increase in the growth of mandible which was stunned due to ankylosis. And the ramal height also increased. CONCLUSION: The articular reconstruction with alloplastic or autogenous grafts, or gap arthroplasty for the treatment of ankylosis is shown to be efficient in relation to the post-operative maximal incisal opening, recurrence and articular function.
RESUMEN
The management of parotid fistulae has been unsatisfactory in the past, and numerous methods of treatment with varying success and morbidity have been described. A case of parotid fistula caused by damage to glandular elements during a transparotid approach for a subcondylar fracture reduction is reported. This paper presents a simple but effective and conservative method of treating this complication with the use of hot hypertonic saline.
RESUMEN
Angiofibroma is a rare, highly vascular nonencapsulated tumor, which is locally invasive. A rare case of angiofibroma of the mandible in a 16-year-old female patient is reported here. The lesion was excised along with surgical removal of right mandibular third molar tooth. Patient was followed up for 1 year without any recurrence.
