Morphological variations of human ossicula tympani.

In a series of 100 cases, morphological variations of human ossicula tympani were studied. These have seldom been considered either in classic or recent descriptions. Among them, the malleus and stapes are the most variable ones. A geometric model is proposed to systematically study any variation from the typical ossicles. These morphological variations of ossicles could be related to age, sex, race, and could bring out peculiarities in acoustic transmission.

[Effectiveness of tonsillectomy, evaluated by acoustic rhinometry].

Hypertrophy adenoid commonest cause of nasal obstruction in paediatrics. The morbility can be try alteration in the respiratory physiology, as well as in the face development and function of the middle ear. We used the acoustic rhinometry to evaluate the surgical results of the adenoidectomy in children with hypertrophy adenoid, compiling the data on their clinic, and correlating them as well with the rhinometric results. The acoustic rhinometry is a relatively new method of exploration of the nasal cavity. We obtain space measures that are going to allow to us to prove it. These measures are the cross-sectional areas and volumes registered in the nasal cavity when this cavity is divided longitudinally in two zones, the previous one until 32 mm measured from the narina, and the later one to 64 mm from the same point. For this study we have taken 45 patients with hypertrophied adenoids. We have made measurements pre and post surgery. Our results show a clear gain in areas as in volumes after surgery and also show the utility of the acoustic rhinometry like method of exploration at the time of quantifying the morphometric alterations of the nasal cavity.
