Otological outcome in cleft lip and palate children with middle ear effusion.

To evaluate the factors contributing to middle ear pathology, hearing and speech development among cleft palate children treated for middle ear effusion. A prospective cross-sectional otoscopic and audiological analysis was conducted on 102 cleft palate children (204 ears) aged 1-18 years old who were treated for middle ear effusion at our centre. Retrospective chart review was done to determine patient characteristics and prior patient management. The aim was to assess the effect of ventilation tube insertion (VTI) on hearing, speech and chronic otitis media; comparing the timing and number of ventilation tubes per ear and determining other factors affecting the short-term and long-term outcome. 68 children or 130 ears (63% of all cases) were selectively treated with ventilation tube insertion. Repeat procedures (more than 2) were performed in 41 ears. Among children with VTI performed, the incidence of chronic otitis media in children after the age of 4 was 17%. Overall, abnormal tympanic membrane findings and hearing loss were detected in nearly half the cases who were previously treated with VTI. Early ventilation tube insertion at less than 1 year of age, resulted in a better middle ear and hearing outcome in children less than 4 years old (p < 0.05), however there was no significant difference in children more than 4 years old. Early surgical repair of cleft palate prior to the age of one year resulted in favourable results in both age groups (p < 0.05). There was a higher prevalence of chronic otitis media with repeated grommet insertion (3 or more) (p < 0.05). Speech and language milestones were achieved in 94% of all children above the age of four. Treatment with early ventilation tube insertion prior to the age of one year provides a hearing benefit in children less than 4 years of age, but no significant difference after 4 years of age. Factors significantly affecting the outcome after 4 years of age was the timing of palatal closure and total number of tube insertions. We recommend a conservative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood.
