Tratamiento de la anquilosis de la articulación temporomandibular por artroplastia simple
Objetivo: El propósito de este trabajo es mostrar que la artroplastia simple mejora la apertura bucal al tratar la anquilosis temporomandibular. Pacientes y métodos: Fueron tratados ocho pacientes con anquilosis de la articulación temporomandibular por medio de artroplastia simple. Los pacientes fueron evaluados en el postoperatorio por un periodo por lo menos de veinticuatro meses (mínimo 24 y máximo 48 meses). Resultados: De los ocho pacientes (once articulaciones), cinco (62,5%) presentaron afectación unilateral y tres pacientes (37.5%) afectación bilateral de la ATM. La edad media fue de 20 años ± 9 (rango de 3 a 30 años). La máxima apertura bucal en el período preoperatorio fue de 9,25…
Facial nerve paralysis after impacted lower third molar surgery: A literature review and case report
Facial nerve paralisys (FNP) is the most commom cranial nerve disorders and it results in a characteristic facial distortion that is determined in part by the nerves branches involved. With multiples etiologies, these included trauma, tumor formation, idiopathic conditions, cerebral infarct, pseudobulbar palsy and viruses. FNP during dental treatment is very rare and can be associated with the injection of local anesthetic, prolonged attempt to remove a mandibular third molar and subsequent infection. We report a case of a 21 years-old black woman who developed a Bell?s palsy after an impacted third molar surgery under local anaesthesia, present a FNP classificated like a grade IV by the Ho…
Surgical treatment of temporomandibular joint ankylosis : follow-up of 15 cases and literature review
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. Purpose: To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or alloplastic condylar implants; evaluate the results of these surgeries and make a literature review. Methods: The sample was obtained from the records of the Oswaldo Cruz University Hospital (HUOC-UPE) of patients submitted to ankylosis treatment by alloplastic or autogenous graft between March 2000 and…
Facial nerve injury following surgery for the treatment of ankylosis of the temporomandibular joint
Objective: The purpose of the present paper was to carry out a longitudinal study of a series of cases in which injury of the facial nerve was observed following surgery for the treatment of temporomandibular ankylosis. Study design: The sample was composed of 13 patients, both male and female, in whom 18 surgical approaches were made. A postoperative assessment of the motor function of the facial nerve was made in accordance with the HouseBrackmann grading system. All the patients were photographed and assessed at the following postoperative times: 24 hours, one week, one month and three months. Results: The results showed that injury of the facial nerve occurred in 31% of the cases. An in…
