Twohundrednineteen orofaciomaxillary tumours, 18 benigns and 201 malignancies, were repaired by pectoralis major myocutaneous flaps following their resections. The types of flaps used in the repair were: single island myocutaneous flaps in 201 cases, doubleisland myocutaneous flaps in 16 cases, and myocutan eous skeletal flaps in 2 cases. The results were susscessful in 201 cases and failure in 18. The advantages and indications of using pectoralis major myocutaneous flaps were discussed. The method of design and its relevent surgical thechniques were introduced, and the factors responsible for the success and failure were analyzed. It is noted that the correct and meticulous operative techniques were the main factors leading to operative success.
The paper reported the clinical experience of using pectoralis major myocutaneous flap for the immediate repair of massive defects from excising the oral and maxillofacial malignant tumours in 21 cases from 1985 to 1993. The valuation, design, preparation, technique of transfer of the flap and the prevention of flap from necrosis were discussed. It was suggested that the pectoralis major myocutaneous flap was worth using for the immediate repair of massive defects around oral and maxillofacial regions.
Objective To evaluate the effectiveness of the submental island flap for repair of oral defects after radical resection of early-stage oral squamous cell carcinoma (OSCC). Methods Between February 2010 and August 2011, 15 cases of early-stage OSCC were treated. Of 15 cases, 9 were male and 6 were female, aged from 48 to 71 years (mean, 63 years). The disease duration was 28-73 days (mean, 35 days). Primary lesions included tongue (3 cases), buccal mucosa (8 cases), retromolar area (2 cases), and floor of mouth mucosa (2 cases). According to TNM classification of International Union Against Cancer (UICC, 2002) of oral cancer and oropharyngeal cancer, 2 cases were classified as T1N0M0 and 13 cases as T2N0M0. The results of the pathologic type were high differentiated squamous cell carcinoma in 11 cases and moderately differentiated squamous cell carcinoma in 4 cases. The defect after resection of the lesion ranged from 5 cm × 3 cm to 8 cm × 6 cm. All the cases underwent radical resection of the primary lesion and immediate reconstruction with submental island flap except 1 case with radial forearm free flap because of no definite venous drainage. The sizes of the submental island flap varied from 6 cm × 4 cm to 9 cm × 6 cm. Results Operation time ranged from 4 hours and 30 minutes to 7 hours and 10 minutes (mean, 5 hours and 53 minutes) in 14 cases undergoing repair with submental island flap. All the flaps survived completely in 13 cases except 1 case having superficial necrosis of the flap, which was cured after conservative treatment. Temporary marginal mandibular nerve palsy occurred in 1 case, and was cured after 3 months; submandibular effusion was observed in 3 cases, and was cured after expectant treatment. The follow-up period ranged from 8 to 15 months (mean, 10.5 months) in 14 cases undergoing repair with submental island flap. Hair growth was seen on the flap and became sparse after 3 months in 2 male cases. The appearance of the face, opening mouth, swallowing, and speech were recovered well in 14 cases, and the donor site had no obvious scar. The follow-up period was 13 months in 1 case undergoing repair with radical free forearm flap, and the appearance and function were recovered well. No local recurrence was found during follow-up. Conclusion The submental island flap has reliable blood supply, and could be harvested simply and rapidly. It can be used to repair oral defects in patients with early-stage OSCC after radical resection.
Objective To investigate the characteristics of the clinical application of ulnar artery flap in the repair of oral and maxillofacial soft tissue defects. Methods The clinical data of 12 patients with oral and maxillofacial defects repaired with ulnar artery flap between June 2021 and July 2023 was retrospectively analyzed. Among them, 11 cases were male and 1 case was female; their ages ranged from 28 to 76 years, with a mean age of 54.8 years. The lesions were located in the lateral margin of the tongue in 3 cases, the root of the tongue in 2 cases, the base of the tongue in 4 cases, and the buccal region, upper gingiva, and lower lip in 1 case each. The pathological types were squamous cell carcinoma in 11 cases and adenoid cystic carcinoma in 1 case; according to the TNM staging of the International Union Against Cancer (UICC), there were 5 cases of T3N0M0, 2 cases of T3N1M0, 1 case of T4aN0M0, 1 case of T4aN1M0, 1 case of T4aN2bM0, and 2 cases of T4aN2cM0. After complete resection of the lesion, the defect ranged from 6 cm×3 cm to 8 cm×5 cm. Preoperatively, colour Doppler ultrasound was used to detect the non-dominant forearm, measure the thickness of the subcutaneous fat in the donor area, confirm and mark the ulnar artery and reflux vein, and measure the diameter of the vessels, flow velocity, and the perforator position; intraoperatively, the flap was designed, prepared, anastomosed, and positioned according to the corresponding data. The vessels were all anastommosed with one artery and two veins to form a super-reflux. After complete hemostasis, the defects were repaired with sliding flap (2 cases), direct suture (4 cases), biomembrane (2 cases), or razor thin skin graft (4 cases). Results No vascular crisis occurred after operation, and all the flaps survived in 12 cases. Wounds in the donor site healed by first intention in 10 cases and by second intention in 2 cases. Wounds in the recipient site healed by first intention in all cases. All 12 patients were followed up 5-18 months, with an average of 11.4 months. The colour and texture of the flap were normal. The function of hand and upper limb was evaluated according to the trial standard of upper limb function assessment of the Chinese Society of Hand Surgery of the Chinese Medical Association, and the score was 65-81 (mean, 71.3), and achieved excellent in 1 case and good in 11 cases. The score of Oral Health Impact Scale (OHIP) was 9-18, with an average of 14.2, and the oral function was satisfactory. During the follow-up, 1 case had local recurrence and underwent extended resection again, while the other patients had no recurrence or metastasis. Conclusion For moderate soft tissue defects with complex oral and maxillofacial function, ulnar artery flap repair is effective.
Objective To evaluate the preliminary effect of using the sternal head of the sternocleidomastoid myocutaneous flap to reconstuct a defect in the maxillofacial region. Mathods From May 2004 to September 2006, 5 male patients aged 2334 underwent the reconstruction for the defect in the maxillofacial region by using the sternal head of the sternocleidomastoid myocutaneous flap. Their defects were caused by an infection of the face, an injection of medicine in the mother’s uterus or a scar or depressed abnormality left by an electric injury. The defects ranged in size from 5 cm×3 cm to 9 cm×6 cm. Results All the 5 sternocleidomastoid myocutaneous flaps survived, with a little necrosis of the epidermis because of the venous return disturbance, but 2-3 weeks after operation the necrosis healed spontaneously with just a little scar formation around the flap. One patient had weakness in the left shoulder after operation, which almost recovered 6 months after operation. The postoperative follow-up for 1-6 months revealed that 1 patient had a little fat and clumsy appearance in the flap pedicle, 1 patient had an obvious scar at the operation site, but the 2 patients still felt satisfaction. The other 3patients were satisfied with their good appearance at the operation sites. Conclusion The sternal head of the sternocleidomastoid myocutaneous flap can be designed with more flexibility compared with the entire sternocleidomastoid myocutaneous flap. It can provide an enough tissue mass for restoring the defect. The sternal head of the sternocleidomastoid myocutaneous flap is an ideal tissue flap for restoring defects in the maxillofacial region.
