The Vomer Flap in Cleft Palate Repair: A Comprehensive Review of Indications, Techniques, and Outcomes

IntroductionThe vomer flap is a versatile surgical technique used in cleft palate repair, primarily to reconstruct the nasal layer of the hard palate. Its implementation has gained renewed interest due to its anatomical advantages and potential for reducing postoperative complications, especially oronasal fistulas.ObjectiveThis narrative review aims to evaluate the historical evolution, technical variations, clinical indications, outcomes, and limitations of the vomer flap in both unilateral and bilateral cleft palate repair.MethodsA systematic literature search was conducted across PubMed, Embase, and Cochrane Library databases, including studies published from 1981 to April 2024. Articles were selected based on relevance to vomer flap use in cleft surgery, focusing on surgical outcomes, functional results, complication rates, and long-term effects on maxillary growth.ResultsThree main techniques were identified for unilateral clefts: cephalically based, caudally based, and open-book vomer flaps. For bilateral clefts, cephalically based and open-book configurations demonstrated superior anatomical adaptation and lower fistula rates compared to caudally based flaps. The vomer flap is particularly advantageous in early repairs and wide clefts, with evidence suggesting a minimal adverse effect on maxillary development. However, high variability in technique and outcome reporting limits comparability.ConclusionThe vomer flap remains a valuable tool in cleft palate repair, offering a balance between surgical efficacy and preservation of growth potential. It's appropriate application, based on cleft morphology and surgical objectives, can enhance functional and aesthetic outcomes. Further prospective studies are needed to standardize technique and validate long-term benefits.
