Submucous Cleft Palate (SMCP): Indications and Outcomes of Radical Muscle Dissection Palatoplasty in Children Under 4 Years of Age.

ABSTRACT

To delineate the indications, referral sources and outcomes of radical muscle dissection palate repair in the first 4 years of life for patients with submucous cleft palate (SMCP).This study presents a retrospective analysis of a single surgeon's management.All children were treated at Great Ormond Street Hospital, United Kingdom.Twenty-three children with nonsyndromic SMCP were included in this study.All participants underwent radical muscle dissection repair before their fourth birthday.Parameters analyzed included referral sources, indications for referral, extent of anatomical abnormality, and postoperative outcomes.Paediatricians provided the largest proportion of referrals to the cleft lip and palate clinic (39%) due to the presence of cleft lip/palate on prenatal scans or during neonatal examination. Over half (n = 12, 52%) of patients had severe anatomical anomalies being in grade IV (score 8-9), with the classical triad present to some extent in all but 2 of the patients. The main indication for surgery was nasal regurgitation of food and liquid (n = 9, 35%) followed by hypernasality (n = 6, 21%), difficulty feeding (n = 3, 8%), and severe anatomical defect (n = 2; 4%). Postoperatively, the presenting complaint improved in the majority of cases.Nonsyndromic SMCP is often missed, though may present with nasal regurgitation, feeding problems, and/or hypernasality, though may be missed in nonsyndromic children. Early radical muscle dissection repair in the first 4 years of life is safe and effective, facilitating normal speech development.
