Botulinum Toxin in the Nasal Area

Abstract

The use of botullinum toxin type A for esthetic purposes has been used since 1987, turning out as one of the most popular procedures in aesthetics due to the effec -tiveness in softening dynamic wrinkles. The nasoglabelar lines or bunny lines are the re-sult of the contraction of the nasal transversus. They can be primary or secondary, the last ones as a result of muscle blockade in glabelar region, generating a compensatory contraction. As people age the nasal tip tends to fall due to gravity forces and due to the kinetic ac -tion of the depressor of the septum muscle. The application of Botox in this area will only have positive results if the ptosis is of muscular cause. Physical or emotional stress causes the involuntary contraction of the anterior and poste-rior dilator naris (nasal flutter). Also the injection in these muscles produces the stretch-ing of nostrils of very wide noses, when these muscles are active (they can move the ala). Hyperhidrosis of the nasal dorsum is diagnosed through the Minor test (iodinated alcohol and starch). The injection is done in dermis until the skin turns white, 1 to 2 UI per injection, separating them by 1cm. Multiple eccrine hidrocistomas are papula cystic lesion, that were described by Andrew Ross Robinson .At inspection they have a transparent dome through which a blue color is seen, usually confused with blackhead. They are originated in sweat ducts, and come out associated with hyperhidrosis.
