title: Submucous cleft palate: an often-missed diagnosis.
abstract: This study aimed to investigate the age at diagnosis, palatal characteristics, and symptoms of submucous cleft palate (SMCP) and to compare the speech outcomes between 3 operative techniques for primary repair of SMCP.It was a retrospective review of 92 patients diagnosed with SMCP between 1994 and 2008, where patients were treated with 1 of 3 surgical procedures: double opposing z-palatoplasty, radical intravelar veloplasty, or pharyngeal flap.The need for a second procedure was considered a primary outcome measure, with operative failure defined by the need for a secondary operation. Postoperative speech was evaluated perceptually using the Great Ormond Street Speech Assessment.We found that SMCP was diagnosed at a mean age of 3.6 years. At diagnosis, 8% were asymptomatic, 67% had abnormal speech, 49% had recurrent otitis media with effusions, and 47% had hearing loss. Ear, nose, and throat surgery was performed on 37% without the diagnosis of SMCP being made. Subjective impression of a short palate was a predictor for secondary surgery (P < 0.02). Age at repair did not affect velopharyngeal insufficiency outcome; however, repair after 18 months of age led to a higher likelihood of developing articulatory speech errors resulting in the need for more speech therapy.In conclusion, the triad of features of SMCP is well recognized, but our study reveals that a high percentage is seen by physicians who have failed to make the diagnosis despite signs and symptoms being evident. Surgical correction is successful regardless of technique and age, but earlier recognition to prevent speech impairment should be sought.
