During septal surgery, anteroinferior corner of the septum is the area where the dissection is most difficult. The authors tried Cottle's premaxillar approach in various cases and found this method useful. In this approach deviation of the maxillary spine and the crest can be corrected without disturbing the septal cartilage. The authors experience includes 25 cases of traumatic or noninflammatory deviation of the nasal pyramid and cleft palate nose, and 10 cases of septal deviation cases.
In cases of diseases in nasal cavities, the electric potential varies with the degree of inflammation and the changes in the nasal mucosa, for example, deviatio septi nasi. At the time of intra-nasal operations, these potentials permit one to predict the post-operative state. In allergic rhinitis, the potential of the mucosa always remains negative, the same as of the eardrum because of oedema of the turbinates.
Four cases of acoustic trauma developed after a chemical explosion (alylazide) were reported with their 3 months follow up. The amount of damage on the eighth nerve depends on the distance from the site of explosion and head position of the patient. Sign of recovery appeared within a week, first rapidly then slowly. Two of the milder cases recovered completely within a month but remaining two showed persistent high tone drop. One of them complained severe tinnitus. High dose of vitamin B1 and A, ATP preparation were given parenterally, and pantetonic acid was given orally as treatment for all cases.
