ABSTRACT
@#The facial submental artery island flap (FSAIF) is a fasciocutaneous flap supplied by the facial submental artery. It is in close proximity with many oral and maxillofacial regions, and its tex ture and color are similar to those of the head and face. The flap has a constant and sufficient blood supply, and it is easy to prepare and has high survival rates and few complications. According to the tissue carried, FSAIF can be divided into fasciocutaneous flaps, myocutaneous flaps and simple flaps. The flap can also be made into an osteofasciocutaneous (myocutaneous) flap with a mandible to repair maxillary defects. Because this flap is a pedicled flap, it can greatly shorten the operation time, bed rest time and hospitalization time and has been widely used in repairing medium-sized defects of the oral and maxillofacial region. The indications for FSAIF in repairing maxillofacial defects should be strictly controlled. It can be safely used for benign or malignant tumors without cervical lymph node metastasis. For malignant tumors with cervical lymph node metastasis but without extranodal extension, the flap can be used on the premise of thorough neck dissection. The contraindication is cervical lymph node metastasis and extranodal extension of malignant tumors; therefore, other flaps should be selected for repair.
ABSTRACT
Resumen La cirugía reconstructiva de cabeza y cuello es una tarea compleja. Existen varias opciones disponibles para lograr buenos resultados, desde colgajos locales hasta colgajos libres microvascularizados. En este reporte presentamos nuestra experiencia utilizando el colgajo en isla submental para la reconstrucción de defectos de tejido blando de base de cráneo lateral posterior a una resección lateral de hueso temporal secundario a diagnósticos oncológicos otológicos. Se presentan datos demográficos, clínicos, quirúrgicos y resultados de dos pacientes intervenidos durante el primer semestre del año 2020, en los cuales se consiguió un adecuado resultado reconstructivo. Este colgajo es una opción confiable y versátil para reconstrucción en cabeza y cuello.
Abstract Reconstructive head and neck surgery is a complex task. There are several options available to achieve good results, from local flaps to free microvascular flaps. In this article, we present our experience using the submental island flap for soft tissue defect reconstruction of the lateral skull base after a lateral temporal bone resection secondary to otologic cancer. Demographic, clinical, surgical and outcome data of two patients operated on during the first semester of 2020 are presented, in whom a good reconstructive result was achieved. This flap is a reliable and versatile option for head and neck reconstruction.
ABSTRACT
Objective@#To summarize the clinical anatomical features and surgical technique of the submental artery perforator flap (SMAPF), and to evaluate the outcome and value of the flap for oral cavity reconstruction after cancer ablation.@*Methods@#A total of 56 patients with oral cancer were included in this study. The modified SMAPF excluded the anterior belly of the digastric muscle and submental fatty tissue. The primary sites of malignancy were buccal mucosa (n=24), tongue (n=21), mandibular gingiva (n=6), mouth floor (n=3), soft palate (n=2).@*Results@#The flap size varied from 3 cm×5 cm to 5 cm×12 cm. Four flaps presented mild venous congestion, which was salvaged with conservative measures such as acupuncture and blood letting. Overall flap survival rate was 100%. The SMAPF with septocutaneous perforator was used in 49 cases and with musculocutaneous perforator in seven cases. External jugular vein and internal jugular vein provides venous drainage were applied in half cases respectively. All the patients showed a good recovery of tongue mobility and mouth opening with a follow-up of 3-41 months. Local recurrence was detected in one patient 4 months after operation.@*Conclusions@#The SMAPF is a reliable flap for oral cavity reconstruction with outstanding functional and aesthetic outcomes.
ABSTRACT
Objective:To investigate the clinical efficacy of reconstruction of the mandibular defect in patients with osteoradionecro-sis using submental artery island flap and reconstructive Ti-plate.Methods:20 cases with mandible osteoradionecrosis underwent par-tial mandibulectomy.The submental artery island flap and reconstructive Ti-plate were used to reconstruct the mandibular defects and adjacent soft tissue defects.The post-operative effects and flap successful rate were evaluated with a follow-up period of 6 to 1 8 months.Results:1 9 flaps were well survived,local necrosis in the remote end was observed in 1 flap,but survived by hyperbaric ox-ygen therapy and iodoform gauze dressing,no plate exposure was found after operation in the follow up period.All patients were satis-factory with the outlook.Conclusion:Submental artery island flap combined with reconstructive Ti-plate is feasible in the treatment of osteoradionecrosis.
