Ecografía cutánea en las cicatrices de acné
¿Puede ser de ayuda la ecografía cutánea en la valoración de las cicatrices de acné?
- Para el tratamiento de las cicatrices atróficas existen tratamientos basados en el remodelamiento superficial como peelings, laseres ablativos y subablativos.
- No obstante cuando existen tractos fibrosos en el interior que producen retracciones dérmicas en las cicatrices en sacabocados. En la actualidad se recomiendan técnicas como la subcisión, que liberan estos tractos previa a los tratamientos de remodelamiento superficial para un resultado óptimo.
No olvidemos que la ecografía cutánea puede aportar información sobre la inflamación subclínica que pueden presentar estos pacientes y que es necesario tratar previo a cualquier tratamiento de este tipo.

Abstract
BACKGROUND:
Consensus concerning nomenclature and classification of acne scars is lacking. Classification based solely on clinical examination represents an unmet need that could be improved with the use of objective, reproducible assessments.
OBJECTIVE:
To assess clinical and ultrasound morphologic features in 41 patients with scars resulting from moderate to severe acne and to determine whether correlation exists.
MATERIALS AND METHODS:
Eighty-one lesions clinically identified as boxcar, ice pick, rolling, hypertrophic, or keloidal were evaluated using high-frequency ultrasound (22 MHz).
RESULTS:
Ultrasound results generally correlated with clinical appearance. Eight scars clinically classified as ice pick showed a typical boxcar morphology upon ultrasound examination. Ultrasound showed that ice pick and boxcar scars were the deepest, with 95.8% between 0.2 and 0.5 mm.
CONCLUSIONS:
High-frequency ultrasound is a noninvasive technique that is useful in the evaluation and correct classification of acne scars. It represents an important adjunct to clinical examination, because it provides reliable objective and reproducible information useful to the selection of the best treatment option specifically customized to each individual patient’s needs.
