Benign jaw tumors.

The jaw bones may develop the same types of tumors as the other bones of the body but may also develop tumors arising from the alveolar processes (epulis) and the developing teeth (odontomes). They are usually benign in nature and can affect the functions of mastication, swallowing and cause facial deformity. They make about 3% of all bone tumors with a tendency for a local recurrence if a wide excision is not contemplated at the first attempt.

Comparative study of underlay tympanoplasty with temporalis fascia and tragal perichondrium.

The perforations of the tympanic membrane maybe of traumatic origin or due to chronic suppurative otitis media. If the perforations fail to heal conservatively, they require surgical closure. Autologous graft materials have stood the test of time in repairing tympanic membrane perforations.
