RESUMO
The rate of spontaneous healing of tympanic membrane perforations in relation to time after blast injury, size, and location of perforations, was evaluated in 147 patients (210 ears). In 46 patients a paper patch was placed over the perforation. Spontaneous healing was seen in 155 ears (74%), 131 (62%) healed within the first 3 months and 145 ears (69%) healed within 10 months. Large and central kidney-shaped perforations had the least tendency to heal and usually required surgical intervention. Tympanoplasty was performed on 33 ears (15%), ossiculoplasty on 5 and mastoidectomy on 10. Intervention is recommended when the tympanic membrane remains unhealed for at least 10 months.

The course of middle ear injuries secondary to blast effect was evaluated in 147 soldier-patients (210 ears) during the years 1967-1986. All perforations were in the pars tensa of the tympanic membrane. Ossicular chain interruption (11 ears) was associated mainly with dislocation of the incudo-stapedial joint. Mixed-type hearing loss was most prevalent (37%). Spontaneous closure occurred in 155 ears (73.8%), most of them (65.5%) within a 3-month period. Seven ears (3.3%) developed simple chronic suppurative otitis media; in 10 (4.8%), an invasive cholesteatoma developed, and in 6 others (2.8%), epithelial pearls were encountered behind an intact eardrum. Thirty-two patients were treated by immediate patching of the perforated drum, with an 84% rate of spontaneous closure; no cholesteatoma developed among this group, emphasizing the need for immediate patching. Tympanoplasty is recommended 1 year following the injury, and a 4-year follow-up period for detection of late complications is also recommended.

The involvement of the temporal bones by fibrous dysplasia is uncommon. This disease is usually manifested by a conductive hearing loss. We describe a case of fibrous dysplasia misdiagnosed as an osteoma in a young man. This case emphasizes the need to suspect fibrous dysplasia of the temporal bone as the cause of bony lesions in the external auditory canal in young patients.

Papillae were removed from a 2-yr-old boy with juvenile squamous cell papillomatosis and the tissue was grown in vitro. The method leading to the establishment of a continuous laryngeal papilloma cell line is described. This epithelial cell line was benign, as judged by cell morphology and cellular inability to form colonies in soft agar or to produce growing nodules in nude mice. Papilloma virus particles were not seen through the electron microscope. In the early stages of culture, the cells contained antigen that stained specifically with autologous serum.
