A study of the residual changes of Osteomylitis of maxilla in infant in respect to alteration in the external appearance of the face, dentition, vision and intranasal and roentgenographic fi ndings was made in 29 cases, 1 to 20 years after the original lesion had healed.
1) External alterations of the face were observed in over a half of the cases, with the largest number showing healed scars of incisions or fistulas.
2) Loss of deciduous teeth was noted, mostly canines and next lateral incisors. Loss of teeth was closely related to whether or not operation had been performed. There was irregularity in the arrangement but no loss of permanent teeth.
3) Ophthalmologic complications consisted of optic nerve atrophy in 1, strabismus convergeus in 2, strabismus divergens in 1 and weak vision in 3 cases.
4) In Roentgenographic examination, acute inflammation does not affect the growth of the sinus, but when the immature maxillary sinus is afflicted with chronic inflammation or subjected to radical operation, pnuamatization is strongly suppressed temporarily or the cavity is obliterated In the cases of obliterated sinuses, 6 showed regeneration with advance in years.
5) Intranasal findings or subjective symptoms that could be referred to the disease in infancy were not found.
6) It is evident from the results that the two sequelae of any clinical importance are disfi gurement of face and malocclusion of teeth. Operation, however, should not be indiscriminately condemned. Surgical treatment should be given early, whenever necessary, after appropriate antibiotic therapy, taking care not to injure the orbital wall nor remove any normal teeth and avoid incisions on the face.
