RESUMO
A case of TMJ ankylosis following otitis media and mastoiditis is described and its treatment presented. The infectious etiology of ankylosis is reviewed, with emphasis on mastoid infections. Theories are presented as to the possible mechanisms by which such infections can spread into the glenoid fossa.

This paper describes a modified preauricular surgical approach to the TMJ used in more than 272 joint surgeries since October 1984. During this time, only four surgical procedures have resulted in postsurgical paresis of the frontal branch of the facial nerve. The technique is a modification of the preauricular approaches described by Al Kayat, Bramley, and Dolwick. Relevant anatomic studies that relate to the frontal branch of the facial nerve and associated fascial layers are discussed. From findings of current anatomic dissections, a safe preauricular approach to the TMJ is described, with emphasis on following certain landmarks.

Cyclic AMP-dependent protein kinase activity, subcellular distribution, and isozyme profile were compared in rabbit, rat, guinea pig, and mouse in both parotid and submandibular glands. Glands were homogenized under hypotonic conditions and the following fractions isolated: 600 g pellet, 27,000 g pellet, and 27,000 g supernatant. The specific activity of the enzyme was similar in the eight glands and was highest in the 27,000 g supernatant. The average activity in the 27,000 g supernatant was approximately 75% of the total gland activity, although there was considerable variability between tissues and species. After being washed with isotonic buffer, this percentage was increased to an average of 84%. When isozyme patterns of the kinase were examined, the rabbit parotid was unique in that it contained a high percentage of isozyme I as isolated on DEAE cellulose columns.
