SORIA, J.H.; CACHAY VELASQUEZ, H. A.  and  LOSARDO, R.J.. Anatomic and clinical study of the depressor septi nasi muscle. Cir. plást. iberolatinoam. [online]. 2012, vol.38, n.3, pp.207-214. ISSN 1989-2055.  https://dx.doi.org/10.4321/S0376-78922012000300002.

The relationship between the rhino-gingivolabial syndrome and the hypertrophy of the depressor septi nasi muscle was investigated. We identified and dissected this muscle through a transfixion interseptum-collumelar incision extended laterally along the vestibular floor in 62 patients submitted to rhynoplasty and divided in 3 groups according to the appearance or absence during facial mimic of: 1-curvature of nasal dorsum; 2-descending nasal tip; 3-shortened columella; 4-inferior displacement of the nasal tip when speech; 5-shortened upper lip; 6-transverse crease in the mid-philtral area. 7-increased maxillary gingival show during the facial animation. We found a 20 % of hypertrophic muscle, with a more anterior distal insertion. Furthermore of muscle division or resection as surgical indication, botulism toxin, can be used to treat this condition with patient´s satisfaction.
