[Integrated assessment of middle ear dysfunction in cleft palate patients and optimization of therapeutic schedule].
OBJECTIVE
To explore evaluation strategies for middle ear dysfunction in cleft palate patients, to optimize the diagnosis and treatment of this dysfunction, and ultimately to improve the comprehensive treatment of cleft palate.


METHODS
The relationship among abnormal tympanic types (B, C, and Anomaly), effusion rate, tympanic pressure, and hearing loss were analyzed. We collected relevant information on 469 ears of cleft palate patients and traced one-year longitudinal changes in the tympana of 124 ears from 62 patients with both cleft lip and cleft palate.


RESULTS
The effusion rates of cleft palate patients with type B, type C, and type Anomaly were 50.3% (97/193), 34.8% (8/23), and 20.9% (53/253), respectively. The tympanic pressure of the ears with and without effusion showed no significant difference (P>0.05). The hearing loss in type B cleft palate patients with middle ear effusion was worse than that in patients without effusion (P=0.001). However, the hearing loss in type Anomaly showed no difference (P>0.05). The constituent ratio of each tympanic type remained constant during the period between cheiloplasty and palatoplasty for cleft lip and palate patients (P>0.05).


CONCLUSIONS
Cleft palate patients of all tympanic types may all suffer from middle ear effusion at different rates. Examination by centesis is suggested for ears with abnormal tympanic types. Early aggressive therapy is essential for type B cleft palate patients with middle ear effusion to avoid hearing loss. However, catheterization may be not necessary for type Anomaly patients, and conservative observation should be performed instead. Myringotomy with grommet insertion during palatoplasty does not delay treatment timing for patients with both cleft lip and cleft palateg.
