title: Advances in the treatment of children with phonological disorders.
abstract: BACKGROUND
  Treatment of phonological disorders considering extra-linguistic and linguistic variables are important to ensure that the alteration is resolved promptly and in the best manner as possible.
  
  
  OBJECTIVE
  To analyze therapeutic advances (phonetic inventory, phonological system, and distinctive features) in children with phonological disorders by considering the therapeutic approach used, the severity of the phonological disorder, age, and the number of therapeutic sessions.
  
  
  METHODS
  We conducted a case series study of 94 children aged 3 years, 9 months through 8 years, 5 months. The children were divided into groups based on the therapeutic approach used (Modified Cycles, Maximal Oppositions, ABAB-Withdrawal, and Multiple Probes), the severity of their phonological disorder, age, and the number of therapy sessions with each individual. Phonetic inventory, the phonological system, and the number of altered distinctive features were analyzed.
  
  
  RESULTS
  The greater the number of therapy sessions, the greater the number of sounds acquired. The number of sounds present in the phonetic inventory and phonological system increased and the severity of the phonological disorder decreased with all of the therapeutic approaches studied. There was also a reduction in the incidence of altered distinctive features.
  
  
  CONCLUSIONS
  There was a favorable evolution in phonetic inventory and phonological system acquisitions as well as a reduction in the number of altered distinctive features for all 3 therapeutic models regardless of the severity of the phonological disorder, age, or number of sessions.
