Intra-Lesional Injection of Triamcinolone to Palatoplasty Scar to Aid Reversal of Transverse Maxillary Relapse after Orthognathic Surgery.

ABSTRACT: A 32-year-old female with a repaired right unilateral cleft lip and palate underwent several surgical and orthodontic procedures during the rehabilitation process of her condition. Nine years after this extensive treatment she underwent transverse relapse of her maxilla and requested a consultation for its correction as she felt her speech and chewing were negatively affected. She presented with a transverse maxillary arch collapse on the cleft side with significant palatal scarring secondary to multiple palate procedures. A course of maxillary expansion and dental alignment with fixed orthodontic appliances was carried out. in addition, she had 2 triamcinolone injections 7 months apart while undergoing orthodontic treatment and one 10 months after completion to soften the scarred palatal tissues. The maxillary arch was successfully expanded and aligned. She was retained with a removable chrome cobalt palatal frame to be used full-time and assure stability of the correction. She has been followed for 4 years with no clinical evidence of relapse. Triamcinolone injection into significant palatal scarring in cleft palate patients with a decreased transverse maxillary dimension can be considered an adjunct procedure in conjunction with orthodontic treatment.
