Primary treatment for cleft lip and/or cleft palate in children in Japan.

OBJECTIVE

To investigate current trends in primary treatment for children with cleft lip and/or cleft palate in Japan.

DESIGN

Nationwide, retrospective study under the direction of the Academic Survey Committee of the Japanese Cleft Palate Association based on analysis of data obtained via a booklet-style questionnaire completed by institutions providing primary treatment for cleft lip and/or palate patients. PARTICIPANTS, PATIENTS: Patients were 4349 children undergoing primary repair for cleft lip and/or palate at 107 participating institutions between 1996 and 2000.

MAIN OUTCOME MEASURE(S): Cleft type, laterality; use of infant palatal plate; and timing and technique of primary repair for cleft lip and/or palate were evaluated by cleft surgeons at 107 participating institutions.

RESULTS

Of a total of 2874 patients with cleft lip and palate or cleft palate only, infant palatal plates were used with 1087 (37.8%) and were not used with 1787 (62.2%). Primary unilateral lip repair was performed at the age of 2 to 6 months in more than 90% of patients. Bilateral cleft lip was treated by one-stage repair in 285 patients (44.5%) and by two-stage repair in 258 (40.2%). Primary one-stage palatal repair was performed in 2212 (76.9%) and two-stage palatal repair in 262 (9.1%) cleft palate patients. Information on treatment of the remaining 400 (14%) patients was unavailable.

CONCLUSION

This investigation clarified current trends in primary treatment for cleft lip and/or palate in Japan. The results suggest the need for an increase in regional core hospitals and greater variation in treatment options.
