[Relations between the maxillary sinus and upper maxillary process. Anatomotopographic study]. / Relaciones entre seno maxilar y apófisis alveolar maxilar superior. Estudio anatomotopográfico.

The anatomic proximity of the antral floor and superior alveolar processes favors the propagation of infections from teeth to neighboring structures, as was pointed out first by John Hunter. A radiologic and anatomic study was made of these anatomic relations and the bony substance between the alveolar ridge and maxillary sinus was measured. No firm criteria for normality could be established because of the variability of the maxillary sinus. Variations in environmental and developmental conditions easily modify its morphology.

[A tubal mucociliary transport study: scintigraphy versus saccharin. A comparative study]. / Estudio del transporte mucociliar tubárico: escintigrafía versus sacarina. Estudio comparativo.

We have studied two different tracers in order to evaluate tubal mucociliary transport time: albumin typed with Technetium-99 and a saccharin solution. The procedure has been done in a group with normal ears and tubes, and in another one with chronic otitis media. Tubal transport time obtained is always longer with saccharin than with albumin between 21% and 66%.

[Cholesteatoma of the middle ear. An enzymatic study]. / Colesteatoma del oído medio. Estudio enzimático.

Forty specimens of aural cholesteatoma have been studied histoenzymological techniques. Acid phosphatases were the most representatives.

[Cancer of the mobile portion of the tongue: a review study]. / Cáncer de la porción móvil de la lengua: estudio de revisión.

32 cases of cancer of the mobile portion of the tongue are studied. Comments are made about its aetiology, diagnosis and results of different treatment techniques.
