Objective: To summarize the application of temporalis muscle flap in the salvage nasopharyngectomy for advanced recurrent nasopharyngeal carcinoma (rNPC), and to provide guidance for the repair of extensive skull base defects in salvage rNPC. Methods: A total of 54 patients with the application of temporalis muscle flap in the salvage nasopharyngectomy for advanced rNPC were retrospectively analyzed, including 42 males and 12 females, aging from 29 to 71 years. There were 36 patients with rT3 and 18 patients with rT4. The surgical methods of temporalis muscle flap repair were summarized. The general situation, survival time and postoperative complications of patients were recorded, and the advantages and disadvantages of temporalis muscle flap were discussed. Results: The temporal muscle flap could completely cover the defect area of nasopharynx and skull base, without the need for other autologous repair materials. The follow-up period was 2 to 28 months. The survival rate of temporalis flap was 98.1% (53/54). The 1-year overall survival rate was 84.5% while 1-year progression-free survival rate was 49.0%. None of the patients had facial nerve injury. Three patients (5.6%) had necrosis of the cranial membrane required surgical intervention and four patients (7.4%) required a chonoplasty due to severe chonostril stenosis or chonostril atresia. Eleven cases (20.4%) had mouth opening restriction, chewing weakness, dysphagia and other eating difficulties. Conclusions: Temporalis muscle flap is an alternative flap for the salvage nasopharyngectomy for advanced rNPC. Temporal muscle flap shows high survival rate and wide coverage, but the surgeon should apprehend the possible complications and reduce the occurrence of them.

OBJECTIVE: To review the research progress of the principle and clinical application of keloid core excision technique. METHODS: The literature on keloid core excision technique at home and abroad in recent years was extensively reviewed, and the principle, development history, indications, advantages and disadvantages of this technique were summarized, and the existing controversies were analyzed. RESULTS: Keloid core excision is a technique to remove the inner fibrous core from the keloid and cover the defect with the keloidal flap. It reduces the wound tension, yields good aesthetic results in the treatment of ear keloids, and reduces the recurrence rate of keloids combining with adjuvant therapies. CONCLUSION The keloid core excision technique has specific advantages, yet its overall efficacy remains controversial. Further studies are imperative to explore the mechanisms regarding keloid recurrence and the vascular supply principles of the keloidal flap. It is also necessary to define appropriate surgical indications and safety protocols of this technique.

OBJECTIVE: The role of different local flaps in small external nasal skin defect reconstruction was discussed. METHOD: Forty-two cases of the small size nasal defects (diameter < 2 cm) were repaired with local external nose flap (includes the dorsal nasal flap, nasolabial flap and bilobed flap). The clinical and follow-up data were analyzed of patients with small external nasal skin defects, who accepted different local flaps reconstruction. Dorsal nasal flap, nasolabial flaps (includes island flap, slid flap and axial flap) and bilobed flap were tailored to reconstruct different external nasal defect. Twenty-seven patients were male and fifteen patients were female, the patients' age ranged from 28 to 74 years, the median age was 61 years. Thirty-eight cases resulted from resection of skin malignant tumor and four cases were benign lesions. The diameter of defects was 1-2 cm. The defects were reconstructed by single-stage dorsal nasal flap in 7 cases. There were 30 cases of caudolateral nasal defects were reconstructed by nasolabial flap, single-stage island nasolabial flap in 7 cases, axial flap in 18 cases and slid flap in 5 cases. Superior lateral defects were reconstructed by single-stage bilobed flap in 5 cases. RESULT: All defects were repaired successfully. All tissue flaps survived and had not necrosis. There was no tumor recurrence during 3 months to 2 years follow-up. CONCLUSION The dorsal nasal flap, nasolabial flap and bilobed flap can be used safely and effectively to repair the small external nasal defect and have satisfactory curative effect.

OBJECTIVEThis clinical study was to find an effective method to prevent flap from necrosis.

METHODSWhen a flap showed blood flow problems, dexamethasone of 0.3 mg/kg was given intravenously for 2 days. Then the dose was decreased to 0.2 mg/kg at the third and the fourth day. At the fifth and the sixth day, dexamethasone of 0.1 mg/kg was given.

RESULTSA total of 51 flaps with blood flow problems was treated with this method. Thirty of them recovered completely; 18 survived mostly and 3 failed.

CONCLUSIONEarly application of dexamethasone can effectively ameliorate blood flow problems of the flap.

OBJECTIVEThe purpose of this study was to observe the healing process of palate wound with denuded bone restored with transplanted buccal or palatal mucosa and to elucidate the mechanism of maxillary growth inhibition following palate repair.

METHODS32 Japan white rabbits, 5 weeks old, were selected as the subjects for this study. They were divided into 4 groups at random. The rabbits in group I was the control without receiving any treatment. The rabbits in group II, III, IV was surgically denuded the bone of palate, and afterwards, the rabbits in group II were not received further restoration, but rabbits in group III and IV were restored with transplanted buccal and palatal mucosa respectively. From 2 to 14 weeks after surgery, at regular intervals, palatal wounds were observed by using a light microscope. Histological changes were also compared among different groups.

RESULTSIt was found in group II that dense connective tissue was formed 2 weeks after the surgery, and Sharpey's fibers was formed between the scar and bone tissue 4 weeks after the surgery. However, no Sharpey's fiber was found in group III and group IV, and in the latter two groups, the histological character of tissue was similar to that of the control.

CONCLUSIONPrevention of the attachment of Sharpey's fibers to the palatal bone could be effectively accomplished by covering the denuded palatal bone with the transplanted buccal or palatal mucosa.

OBJECTIVETo investigate the surgical techniques and therapeutic effect of eyelid divided nevus.

METHODSFrom January 2000 to January 2014, 27 cases with 27 eyelid divided nevi were treated by staged excision (2 cases), or full-thickness skin graft (20 cases) or frontal and facial expanded flaps (3 cases), or combined expanded flaps with skin grafts (2 cases) for large lesions. One case with skin graft underwent secondary treatment with expanded flap due to obvious scar.

RESULTSExcept for one case with residue lesion (0. 5 cm x 0. 5 cm), all the other cases underwent successful treatment with primary healing. All the patients were followed up for 3-48 months (average, 7. 4 months). Except for one case with secondary expanded flap treatment, all the other patients were satisfied with aesthetic and functional results. No occurrence happened.

CONCLUSIONSStaged excision and full-thickness skin grafts are simple and effective method for eyelid divided nevus. For large lesions, expanded flap, or combined with skin graft should be considered.
