5년령의 암컷 사냥개가 사냥 중 안면부 총상에 의한 구비강 개통으로 내원하였다. 협측피판 및 경구개 점막골막피판술을 이용하여 구개부의 창상성 구비강 개통에 대한 재건술을 실시하였다. 그리고 수술부위의 보호를 위해 인상 과정을 통해 정교하게 제작된 아크릴 부목을 적용함으로써 비교적 큰 결손부를 성공적으로 치유한 증례를 보고하고자 한다.

Background: Oronasal/antral communication, loss of teeth and/or tooth-supporting bone, and facial contour deformity may occur as a consequence of maxillectomy for cancer. As a result, speaking, chewing, swallowing, and appearance are variably affected. The restoration is focused on rebuilding the oronasal wall, using either flaps (local or free) for primary closure, either prosthetic obturator. Postoperative radiotherapy surely postpones every dental procedure aimed to set fixed devices, often makes it difficult and risky, even unfeasible. Regular prosthesis, tooth-bearing obturator, and endosseous implants (in native and/or transplanted bone) are used in order to complete dental rehabilitation. Zygomatic implantology (ZI) is a valid, usually delayed, multi-staged procedure, either after having primarily closed the oronasal/antral communication or after left it untreated or amended with obturator. The present paper is an early report of a relatively new, one-stage approach for rehabilitation of patients after tumour resection, with palatal repair with loco-regional flaps and zygomatic implant insertion: supposed advantages are concentration of surgical procedures, reduced time of rehabilitation, and lowered patient discomfort. Cases presentation: We report three patients who underwent alveolo-maxillary resection for cancer and had the resulting oroantral communication directly closed with loco-regional flaps. Simultaneous zygomatic implant insertion was added, in view of granting the optimal dental rehabilitation. Conclusions: All surgical procedures were successful in terms of oroantral separation and implant survival. One patient had the fixed dental restoration just after 3 months, and the others had to receive postoperative radiotherapy; thus, rehabilitation timing was longer, as expected. We think this approach could improve the outcome in selected patients.

Bone grafting the alveolar cleft allows for stability and continuity of the dental arch, provides bone for eruption of permanent teeth or placement of dental implants, and gives support to the lateral ala of the nose. Closure of residual oronasal fistula can occur simultaneously. Repair of alveolar clefts can occur at a variety of stages defined as primary, early secondary, secondary, and late. Most centers perform this surgery as secondary bone grafting. Autogenous bone provides osteogenesis, osteoinduction and conduction and is recommended for grafting to the cleft alveolus and several donor sites are available. The surgeon should select the best flap design considering the amount of mucosa available, blood supply and tension-free closure, and the extent of the oronasal communication. The authors provide a comprehensive understanding of alveolar clefts and their repair by reviewing the historical perspective, objectives for treatment, timing, source of graft, presurgical orthodontics, surgical techniques, postoperative care, and complications.

The author evaluated the effectiveness of pedicled buccal fat pad grafts for closure of oroantral communications. Nine patients with chronic oroantral communications and one patient with an oronasal communication were treated with pedicled buccal fat grafts. They were treated successfully in all cases, and there were no postoperative complications (i. e. shallow buccal vestibule), and minimal patient discomforts. It was concluded that this was a easy and time fast method for closure of oral defects and had wide application and high successful rate.

There are many challenges for reconstruction after intraoral tumor resection. Especially, palatomaxillary reconstruction has two primary goals: closure of the oronasal communication and re-creation of proper myomucosal function. Prosthodontic treatment using obturator and several surgical procedures are selected depending on the size and site of the defect, the difficulty of operative procedure, operation time and donor site problem. Above all, it is considered that radial forearm free flap is the first choice for palatal reconstruction. Our department introduces a novel method using tunnelized-facial artery myomucosal island flap for palatomaxillary defect reconstruction, which can successfully reduce donor-site morbidity, and duration of surgery and hospitalization.

Objectives: Cleft lip and palate (CLP) is one of the most common congenital deformities with worldwide prevalence. It causes a range of issues for infants that mainly involve difficulty in feeding due to abnormal oronasal communication. For this purpose, feeding plates are provided to infants to act as an artificial palate to aid in feeding. The most crucial procedure in fabrication of a feeding plate is creation of the impression using the traditional finger technique or impression trays. This preliminary research aims to compare the effectiveness of novel impression trays with that of the traditional finger technique for recording impressions of infants with CLP. Materials and Methods: This randomized controlled trial was conducted among 30 infants who were divided into two groups based on the method of obtaining impressions: Group I, finger technique; Group II, specialized acrylic tray (cleftray). Results: Use of cleftray required less impression time, a reduced amount of material, no incidence of cyanosis/choking in infants, and lower anxiety among doctors compared to the traditional method. Additionally, there was no distortion of cleft impressions, recorded maxillary tuberosity, or other fine details. Therefore, the novel impression tray (cleftray) exhibited superior outcomes in all the parameters compared to the finger technique. Conclusion: Within the limitations of this study, we conclude that impression trays are superior to the traditional finger, spoon, or ice cream stick methods of creating impressions of CLP. However, it is necessary to conduct more clinical trials on a larger population based on other parameters to compare the effectiveness of the two techniques to draw definitive conclusions.
