ABSTRACT
Patients with primary hyperparathyroidism have a parathyroid adenoma approximately 80% of the time. Preoperative localization of parathyroid adenomas has been significantly improved by the utilization of high resolution (high frequency) real-time ultrasound. This technique was accurate in 14 (78%) of the 18 cases in our series. There were four false negatives and no false positives. This imaging technique can routinely identify lesions less than 1 cm. High resolution real-time ultrasound is fast, safe, and cost effective. It is an ideal screening test for the preoperative localization of parathyroid adenomas.

The prevalence of serous otitis media has caused a philosophical difference as to when a tympanoplasty should be performed in children. This retrospective study of 74 children (aged 3-17) who underwent 80 operations was undertaken to investigate this problem. The overall success rate for type 1 tympanoplasty was 66%. Age was not a reliable factor in predicting successful results. A history of recurrent serous otitis media was not an important indicator. Adenoidectomy did not influence the surgical outcome. The status of the nonoperated ear was probably a significant factor. Type 1 tympanoplasty has a reasonably good chance of success in children regardless of age and/or previous middle ear ventilation problems. However, a good clinical test of eustachian tube function is still needed to improve further the predictability of timpanoplasty in children.
