Thermal variation in human temporal bone using rigid endoscope.

Objective: Compare thermal variation in the region of the External Acoustic Canal (EAC) and the Round Window (RW) using different rigid endoscopes and light sources in human temporal bones.

Method: This is an analytical experimental study using human temporal bones. Thermal variation was assessed during ten minutes, using a thermometer in the region of the EAC and the RW of two temporal bones, right and left.

Different clinical presentation of intralabyrinthine schwannomas - a systematic review.

Introduction: Intralabyrinthine schwannoma is a rare, benign tumor that affects the most terminal portions of the vestibular and cochlear nerves. This tumor can be classified into 10 subtypes, according to its inner ear location.

Objective: To carry out a comprehensive review of the most frequent auditory manifestations secondary to the intralabyrinthine schwannoma, describing the possible underlying pathophysiological mechanisms.

Effect of trans-retinoic acid in the inhibition of cholesteatoma in guinea pigs.

Unlabelled: Middle ear cholesteatoma affected more than 5 million people until the 80;s. Many animal models were used, unsuccessfully, to study an alternative therapy to cholesteatoma.

Aim: observe the effect of the trans-retinoic acid in the inhibition of middle ear cholesteatomas induced by propylene glycol.

Adeno-tonsillectomy surgery in a joint aid effort: a feasible solution?

Unlabelled: Public hospitals in Brazil are under capacity for adenotonsillectomies, resulting in a growing waiting line. Otolaryngologists are used to these lines, since they understand that this problem is under govern responsibility. For this reason we believe that joint aid efforts to carry out adenotonsillectomies are justified.
