“…The rate of postoperative ONF ranges from 2.4% to 55%, related to the cleft width, Veau type, and surgical method [ 16 , 17 , 18 , 19 , 20 ]. ONF can result in nasal leakage, speech disorders, impaired hearing, and food reflux, significantly impacting the patient’s quality of life [ 21 , 22 ].

An oronasal fistula (ONF) is an abnormal structure between the oral and nasal cavities, which is a common complication of cleft palate repair due to the failure of wound healing. When some patients with ONF are unsuitable for secondary surgical repair, the obturator treatment becomes a potential method. The objectives of the obturator treatment should be summarized as filling the ONF comfortably and cosmetically restoring the dentition with partial function. The anatomy of patients with cleft palate is complex, which may lead to a more complex structure of the ONF. Thus, the manufacturing process of the obturator for these patients is more difficult. For performing the design and fabrication process rapidly and precisely, digital techniques can help, but limitations still exist. In this review, literature searches were conducted through Medline via PubMed, Wiley Online Library, Science Direct, and Web of Science, and 122 articles were selected. The purpose of this review was to introduce the development of the obturator for treating patients with ONF after cleft palate repair, from the initial achievement of the obstruction of the ONF to later problems such as fixation, velopharyngeal insufficiency, and infection, as well as the application of digital technologies in obturator manufacturing.

Purpose of review Massive palatal defects resulting from palatoplasty failures arising from cleft palate repair complications present ongoing challenges in clinical practice. The purpose of this review is to provide up-to-date insights into aetiology, risk factors, surgical techniques, and adjunctive therapies, aiming to enhance the understanding of such complex cases, and optimize patient outcomes. Recent findings Primary palatoplasty has fistula recurrence rates ranging from 2.4% to 55%. Factors such as cleft width, surgical repair method, and patient characteristics, influence the likelihood of failure. Classifications such as the Pakistan Comprehensive Classification and Richardson's criteria aid in assessing defects. Surgical options range from local flaps and revision palatoplasty to regional flaps (e.g., buccinator myomucosal, facial artery-based flaps, tongue flaps, nasal septal flaps) to free microvascular flaps. Alternative approaches include obturator prostheses, and acellular dermal matrix has been used as an adjuvant to multiple repair techniques. Hyperbaric oxygen therapy has emerged as an adjunctive therapy to enhance tissue healing. Summary This comprehensive review underscores the intricate challenges associated with massive palatal defects resulting from palatoplasty failures. The diverse range of surgical and nonsurgical options emphasizes the importance of patient-centric, individualized approaches. Practitioners, armed with evidence-based insights, can navigate these complexities, offering tailored interventions for improved patient outcomes.
