In the past few decades, many mission projects have been held regularly in China. The purpose of this audit was a retrospective analysis of a 9-year cleft lip and palate charity project operated in a tertiary hospital in China Shenzhen Area to evaluate perioperative and postoperative complications. Nevertheless, understanding the risk profile is essential for establishing a sustainable in-house cleft service in Shenzhen. Methods: A detailed analysis of hospital centralized record in the The University of Hong Kong-Shenzhen Hospital (HKUSZH) was reviewed since the first charity project held in 2015. The parameters of this audit were focused on perioperative complications including anesthesia related problems, early postoperative complications in patients who underwent primary or secondary cleft surgeries. A total of 430 consecutive admitted cases of 311 non-syndromic cleft lip & palate patients were enrolled into the charity project from June 2015 to July 2024. The main anesthesia related complications that occurred during general anesthesia were respiratory tract problems, while intraoperative complication was excessive bleeding, so as wound local infection and reaction were the main early postoperative complications. Results: In our 9-year clinical audit of 430 cleft lip and palate charity surgeries in Shenzhen, we observed no mortalities and a anesthesia-related complication rate of 1.16%. Specific intraoperative complications included excessive bleeding, while early postoperative issues were dominated by wound infections. The fistula rate of 18.7% post palate repair and the average hospital stay of 3.71 days complete the profile of our surgical outcomes. These data underscore the project’s efficacy and offer a reference for international cleft missions aiming for safe and efficient surgical care. Conclusions: This study provides a thorough data review of the complications in the past 9 years charity missions for cleft lip and palate surgery in a well-structured hospital infrastructure and logistic support by local surgical team. There were no perioperative or postoperative death during the study period and the overall short-term complication rate was low. Therefore, it could be a reference model for other international cleft mission in developing country for a safe and efficient service in future.展开更多

The success of a repair is assessed by two essential criteria: The functional character of the lip (restoration of continence allowing feeding) and the aesthetic quality of the repair. However, for many patients from countries whose medical infrastructure does not allow them to undertake complex reconstructions locally, medical transfers represent their only chance of treatment. The aim of this article is to share with you an extreme clinical case of labial reconstruction, the management of which was a real challenge, using two major flaps: the free ante-brachial flap and the DUFOURMENTEL-type bi-pediculated scalp flap.展开更多

In the West, their treatment is done under general anesthesia and follows the classic rules of oncology. In our context of exercise, we sometimes have a different attitude dictated by various constraints. Observation: 55-year-old patient with no notable history, seen in consultation for a very large ulcerative-budding lesion on the right 2/3 of the lower lip with mucocutaneous involvement without lymph node findings found on examination. Faced with this suspicious lesion and the patient’s financial difficulties, we decided to operate under local anesthesia to remove this tumor. The oncological excision was followed by immediate plasty using a Camille-Bernard flap with a good immediate aesthetic and functional result and postoperative day 7. The patient was unable to take his surgical specimen to anatomy-pathology and was lost to follow-up due to lack of financial resources. On anatomo-pathological analysis of the surgical specimen, the margins were healthy with confirmation of squamous cell carcinoma (anapathological reading made for scientific interest). Discussion: The particular mentality of certain patients and their difficult financial conditions push us to have an unconventional therapeutic attitude in oncology, but which nevertheless makes it possible to resolve certain problems that we often face. Local anesthesia is possible and realistic in cases like ours and the results can be acceptable and life-saving.展开更多
