BROAD PECTUS EXCAVATUM TREATMENT: LONG TERM RESULTS OF A BRAZILIAN TECHNIQUE

TRATAMENTO DO PECTUS EXCAVATUM AMPLO: RESULTADOS A LONGO PRAZO DE UMA TÉCNICA BRASILEIRA

ABSTRACT

Objective:

This study aims the treatment results of broad pectus excavatum after a long-term follow-up and skeletal maturity.

Methods:

Eighty-four children and adolescents with broad-type pectus excavatum were selected for evaluation after treatment with a dynamic orthosis that applies compression to the lower rib projections and prescription of exercises. The broad pectus excavatum was defined as a deformity that the depressed area was greater and covered the area above and below the nipple line. All patients were evaluated for more than 1 year after the end of treatment and skeletal maturity. Post-treatment results were categorized as mild, moderate and severe. Statistic correlations between results and deformity flexibility, deformity severity, and adherence to treatment were assessed.

Results:

The mean age at the beginning of treatment was 13.3 years, and the follow-up duration was 25.7 months after suspension of orthosis use. Forty-eight percent of patients showed good results. With regular use of orthoses and performance of exercises, this rate increased to 70% (p < 0,001). Mild cases showed more success than severe cases (p = 0,007). Initial flexibility didn’t influence the results (p = 0,63).

Conclusion:

Treatment of broad pectus excavatum with orthoses and exercises led to good definitive results in most resilient patients, especially in those with mild deformities. Level of Evidence V, Expert Opinion.
