RESUMO
OBJECTIVES: The sulphur SPA inhalation therapy is useful in respiratory and otolaryngologic chronic inflammatory diseases in adult subjects and children. The therapeutic action relies on anti-inflammatory, mucolytic and trophic effects. Particularly in children, the sulphur SPA inhalation therapy, using endotympanic ventilation or Politzer method, would be suitable in the treatment of the rhinogenic deafness. Several reports have demonstrated the effectiveness of endotympanic ventilation while the results on the Politzer method are inconclusive. On the basis of these considerations, aim of our study was to analyze the effectiveness and the safety of the aerosol+Politzer with a sulphur mineral water in children affected by rhinogenic deafness or chronic inflammatory processes responsible for the onset or persistence of rhinogenic deafness. PATIENTS AND METHODS: The study has been performed on 23 subjects in pediatric age (61% women and 39% males; mean age: 6+/-2.4 years; age range: 3-14 years) affected by chronic catarrhalis otitis, chronic rhino-pharyngitis inflammations, chronic or recurrent adenoiditis with dysfunction of the Eustachian Tube. The investigated subjects underwent 12 consecutive days sulphur SPA inhalation therapy (aerosol+Politzer) at the Terme of Stabia in Castellammare (Naples, Italy). At the beginning and at the end of the SPA cycle the functionality of the middle ear and the tolerability were evaluated. RESULTS: The results have shown an increase of the impedance curves that correspond to the normal ventilation of the tympanic box (type A (13% before therapy and of 57% post-therapy) and a decrease of the pathological curves of type B and type C (87% pre-therapy and of 43% post-therapy); a significant increase of compliance (p 0.05) in pathological curves of type B and C. No adverse reaction to the SPA inhalation therapy has been reported during the study. CONCLUSIONS: In concordance with the literature our data demonstrated that the sulphur SPA inhalation treatment induce a improvement of middle ear function of the subjects examined with good local and systemic tolerability.
