Myositis Ossificans Circumscripta of the Supra-orbital Region: A Case Report

Myositis ossificans circumscripta is a pathological condition characterized by formation of bony tissue within the skeletal muscles following repeated trauma. A case of myositis ossificans circumscripta of thesupra-orbital region in a 25-year-old man is presented and the pertinent literature is reviewed. To the best our knowledge this benign lesion has not been reported previously in the orbital region the world literature. Clinically the patient presented with a swelling and proptosis of the right eye. Radiologically there was a rounded opacity with well defined margin. Lesion was initially misdiagnosed as a fibroosseous lesion; however microscopic examination indicated matured myositis ossificans. Lesion was excised via a bicoronal flap. Careful clinical, radiological and pathologic evaluation is required to make this uncommon diagnosis in an unusual location such as the supra-orbital region to avoid unnecessary surgical mutilation of the patien

Temporomandibular Joint Ankylosis in a Nigerian Teaching Hospital

Twenty-six patients (12 males and 14 females) between two days and 41 years old with temporo-mandibular joint ankylosis were retrospectively reviewed. Thirty-three joints were involved; 19 unilateral and six bilateral. The aetiologies were trauma, 69.2%; infection, 15.4%; unknown, 11.5% and congenital, 3.9. The majority, 31 were intracapsular while the remaining two joints were extracapsular. 51.6% were limited to the condyle, 32.2% extended to the coronoid process and the zygomatic, 9.7% extended to the sigmoid notch while the remaining 6.5% had maxillomandibular fusion. Tracheostomy (48%) was the most common mode of intubation. Gap arthroplasty was carried out in 20 joints while 11 joints had interposition arthroplasty. Postoperative complications were seven anterior open bite, three facial nerve weakness, three infections and two recurrences.

Las etiologías fueron traumas (69.2%), infecciones (15.4%), causas desconocidas (11.5%) y causas congénitas (3.9%).

El 51.6% estuvieron limitadas al cóndilo, 32.2% se extendían al proceso coronoides y el cigomático, 9.7% se extendían hasta la escotadura sigmoidea, mientras que el restante 6.5% presen-taba fusión maxilomandibular. La traqueotomía (48%) fue el modo de entubación más común. La artroplastia de intervalo se llevó a cabo en 20 articulaciones, mientras que 11 articulaciones tuvieron artroplastia de interposición. Las complicaciones post-operatorias fueron siete casos de mordida abierta anterior, tres casos de debilidad del nervio facial, tres infecciones, y dos recurrencias.

Challenges of Airway Management in a Patient with Temporomandibular Joint Ankylosis Complicating Forceps Delivery: A Case Report

Ankylosis of the temporomandibular joint following forceps delivery is a rare anomaly. The aetio-pathogenesis involves wrongful application of the forceps or forceful closure of the forceps handle against the condyle with haemathrosis, organisation and subsequent ankylosis. Because of the lack of epidemiological data, there is little information about the true incidence and the management of this rare anomaly. The purpose of this presentation is to report the challenges encountered in the airway management of a six-year old female with right temporomandibular joint ankylosis following forceps delivery in a private hospital setting. Keywords: Airway management, ankylosis, forceps delivery "Retos en el tratamiento de las vías respiratorias en una paciente con anquilosis de la articulación temporomandibular complicando el parto con fórceps: Reporte de un caso" RESUMEN La anquilosis de la articulación temporomandibular tras el uso de fórceps siguientes es una rara anomalía. La etiopatogénesis implica la aplicación indebida de los fórceps o el cierre forzoso del mango de los fórceps contra el cóndilo con hemartrosis, organización y subsiguiente anquilosis. Debido a la falta de datos epidemiológicos, hay poca información acerca de la verdadera incidencia y el tratamiento de esta rara anomalía. El objetivo de esta presentación es informar los problemas encontrados en el tratamiento de las vías respiratorias de una niña de seis años con anquilosis de la articulación temporomandibular derecha tras de un parto con fórceps en el contexto de un hospital privado.
