Application of facial-submental artery island flap in reconstruction of oral and maxillofacial defects / 口腔疾病防治

@#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.

Objective:To investigate the surgical method and therapeutic effect on repairing soft tissue defects around ankle with lateral tarsal artery island flap.Methods:From July 2013 to December 2020, the lateral tarsal artery island flap were used to repair the soft tissue defects around ankle in 12 patients in Hand Surgery Department, Jiangnan Hospital Affiliated to Binjiang College. Of which, 6 patients had soft tissue defects complicated with bone or tendon exposure after injury and 6 had skin necrosis with internal fixation after fracture. The area of soft tissue defects was 6.0 cm×4.0 cm-9.0 cm×5.0 cm, and the size of the flaps was 7.0 cm×5.0 cm-10.0 cm×6.0 cm. After the flap was freed, the vascular pedicle was separated up to the origin of dorsalis pedis artery. As the pedicel was not long enough in 1 patient, the dorsal pedis artery was ligated and transected at the origin of the lateral tarsal artery. Full thickness skin graft was used to repair the donor sites. The patients were treated with anti-infection and anticoagulant therapies. The postoperative follow-ups were conducted by outpatient clinic visit, telephone or WeChat interviews or home visit to observe the recoveries in texture, appearance, sensation, donor site and function of ankle.Results:All the flaps and skin grafts survived. The wound healed well without occurrence of ulcer. The follow-up ranged 6-108 months (mean 17 months). Appearance of the flaps was good. It was not bloated and the sensation was restored to S 2-S 3. Conclusion:It is a good method to apply the lateral tarsal artery island flap in repair of the soft tissue defects around ankle. It features a hidden donor site, simple operation and the high level of safety. The texture and appearance of the flap are close to those of the recipient site.

Effect of hallux toe nail flap and adjacent island flap of the middle and ring fingers in repair of degloving injury of distal thumb / 中华显微外科杂志

Objective:To summarise the clinical efficacy and surgical indications for free hallux toe nail flap and adjacent island flap of the middle and ring fingers in repair of distal thumb degloving injuries.Methods:From May 2009 to May 2021, a total of 24 patients (24 digits) with degloving injury of distal thumbs were treated in the Department of Hand and Microsurgery of Baoji Third Hospital. The flap was selected according to the patient's wishes and occupation. Of the 24 patients, 13 were repaired by free hallux toe nail flap transfer (group of hallux toe nail flap), and 11 were repaired by combining the proper palmar digital artery island flap of middle (ulnar side) and ring (radial side) fingers with the same volar common digital artery vascular pedicle (group of tile combined flap). Follow-up was performed at the 1st, 3rd, 6th,12th and 18th months after surgery respectively through outpatient clinic and telephone or WeChat interviews. The follow-ups focused on the appearance, colour, texture and two-point discrimination (TPD) of the flap, as well as thumb flexion, extension, opposition and grasping functions. Functional recovery evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Results:All the 24 flaps survived and all were included in the follow-up. The follow-up lasted 12-60 and 6-18 months, with an average of (18.5±0.5) months and (6.8±0.3) months in group of hallux toe nail flap and group of tile combined flap, respectively. Appearance of thumb body and function at the last follow-up showed: in the group of hallux toe nail flap, the nails, thumbtips and fine sensations were restored, with the TPD at 5-8 mm. The thumb flexion, extension, opposition and grasping functions were good. Apart from without nails and fingerprint, the flaps in the group of tile combined flap had good appearance and texture, and the protective feeling was restored with the TPD at 6-11 mm. The affected thumbs also recovered the basic functions of flexion, extension, opposition and grasping. According to the Trial Standard of Upper Limb Function Evaluation of the Chinese Medical Association Hand Surgery Society, 7 cases were excellent, 5 cases were good, and 1 case was poor in the group of hallux toe nail flap. In the group of tile combined flap, 3 cases were in excellent, 5 in good, and 3 in poor. Appearance of flaps (such as nails and thumbtip fingerprint), fine sensory recovery, and the accuracy and stability of the grasping function, the group of hallux toe nail flap was significantly better than that of the group of tile combined flap. There was no functional impact on the donor site.Conclusion:Both types of flap are classic surgical procedures for repair of distal thumb degloving injury. In order to meet the individual requirement and to improve the efficacy of the treatment, such as for those who have high expectation for digit restoration, especially those who are young with aesthetical or professional requirement, free hallux toe nail flap repair is used to restore the perfect shape and function. And for those who are reluctant to sacrifice their toes or for the middle-aged and elderly people who do not have high expectation for the shape of thumb, a tile combined flap repair is used to restore thumb function.

Objective To compare the clinical effect and operation difficulty of the combined skin flap with reversed proper palmar digital arterial dorsal branch island flap and cross-finger flap and the abdominal flap in the treatment of distal finger degloving injury.Methods Inclusion criteria:①Soft tissue defect far beyond the level of distal interphalangeal joints.②The inured finger was from second to fifth.③Single finger injury.④ Iniury time within 8 h.Exclusive criteria:①With tendon injury.② Multiple finger injuries.③Followed-up time within 6 months.Between February,2009 and September,2016,52 patients (52 fingers) with distal finger degloving injury were reviewed,there were 32 males and 20 females,aged from 18 to 60 (36.02±11.00) years.The time from injury to operation was 2.5-8.0 (4.81±1.28) h.Affected fingers included index finger in 15 cases,middle finger in 22 cases,ring finger in 10 cases,and little finger in 5 cases.Twenty patients (20 fingers) were treated by combined skin flap with reversed digital arterial dorsal branch island flap and cross-finger flap(group combined-flap).The cubital skin was grafted onto the donor sites.Thirty-two patients (32 fingers) were treated by abdominal flap (group abdominal-flap).Results The patients were followed-up 6-25 (9.25±3.97) months.The operation time:group combined-flap was 80-130 (98.46±8.34) min and group abdominal-flap was 85-125(107.84±8.63)min.There was no significant difference in two groups (P＞0.05).Pedicle division time:group combined-flap was 15-24 (16.75±1.74) d and group abdominal-flap was 24-45 (28.31±5.12) d.There was a significant difference in two groups (P＜0.05).And the pedicle division time in group combined-flap was much shorter than in group abdominal-flap.Flap function at last follow-up,the excellent and good rate of the flap in group combined-flap and group abdominal-flap was 90.00％ and 59.38％,respectively.There was a significant difference in two groups (P＜0.05),and the flap function in group combined-flap was much better than in group abdominal-flap.Affected finger function at last follow-up,the excellent and good rate of the affected fingers was 95.00％ and 71.88％.There was a significant difference in two groups (P＜0.05),and the affected finger function in group combined-flap was much better than in group abdominal-flap.Conclusion The combined skin flap with reversed digital arterial dorsal branch island flap and cross-finger flap is a simple and high-survival-rate flap,whose texture,appearance and clinical outcome for repair of distal finger degloving injury are much better than traditional abdominal flap.
