RESUMO
Following the removal of a benign tumour of the maxillary alveolus and sinus, the sinus floor and maxillary alveolus was reconstructed using Biogran sandwich and Biogran onlay respectively. The sandwich technique is new and has not been previously described in the literature. The reconstruction of the maxillary sinus floor and adjacent alveolar bone is an important prerequisite for the placement of an osseointegrated implant in this location. Essentially this new technique involves the use of Biogran sandwiched by Biogide (a resorable membrane) as a unit to reconstruct the maxillary sinus floor, followed by simultaneous placement of Biogran onlay for the reconstruction of the alveolar bone. Based on the results obtained, the technique may be suitable for the reconstruction of other areas of the sinus or oral cavity. These areas include the orbital floor and the bony defects of cleft palate (AU)

Hearing screening is well established in most developed countries, and the data extensively published. However, little information has been presented by the developing, nonwhite populations. A screening study was carried out on 2202 Jamaican children age 5 to 7 years. This involved typanometry and pure-tone audiometry (frequencies of 0.5, 1, and 2 kHz.) Failure was considered to have occurred if a type B or C curve was obtained or if the threshold of hearing was greater than 20 dB. These children were further evaluated by a full ear, nose and throat examination, inclusive of pneumatic otoscopy, and audiologic testing. The prevalence of hearing impairment was 4.9 percent. Otitis media with effusion (OME) was present in 1.9 percent. The prevalence of OME in Jamaica is low when compared with that of the same age-group in the developed countries(AU)

We describe the clinico-pathological features and discuss the possible pathogenetic mechanism of thyroid papillary carcinoma arising in a branchial cleft cyst. This has been described only once previously in the literature. (AU)
