[Multidisciplinary cooperation in surgical treatment of complex head and neck tumor].

OBJECTIVE: To study the multidisciplinary cooperation in surgical treatment of complex head and neck tumors. METHODS: The data from 22 patients with head and neck tumors who had been given neurosurgery, orthopaedic surgery, plastic and otological surgery were reviewed from April 1995 to June 2000. RESULTS: Eight of 14 cases of benign tumors had been resected radical; 5 of 8 malignant cases had been moval of macroscopic tumor and 3 received operation for symptom improvement. No surgical death and serious complications were observed. The recurrence rate benign tumors was 21.4% (3/14), all of which were operated on at other hospitals. Follow-up for a year showed that in 8 cases of malignant tumors, 3 were tumor free, 2 survived with tumor, and 3 died. CONCLUSIONS: To obtain good outcome in treatment for patients with complex tumors of head and neck, cooperative efforts between multidisciplinary surgery are necessary.

[Evaluation for submental island flap].

OBJECTIVE: To evaluate the clinical effect of submental island flap. METHODS: The influence of head and neck radiotherapy and neck lymph node metastasis on the flap was analysed. The clinical effect in the near future and longterm of submental island flap for defects repair was evaluated. RESULTS: Thirty-eight submental island flap were applied for reconstruction of head and neck defects following cancer ablation between July of 1997 to December of 1999. 16 of these had preoperative radiotherapy at both donor site and receive site, and neck dissections with resection of primary lesions were simultaneously performed in 18 patients. The success rate was 89.5% (34 of 38). All repaired cases had well matched skin with facial surface and excellent texture for intraoral function. CONCLUSIONS: Routine preoperative radiation does do not influence the success and healing of the flap. For tumor complete resection, appropriate cases should be chosen. We believe this flap is worthwhile in addition to the existing armamentarium of reconstruction options both facially and intraorally.

[Election for surgery access to skull base].

OBJECTIVE: To seek for a better approach for the resection of skull base tumors. METHODS: A review of 84 skull base tumors resection employed unlike operative approach in the Cancer Hospital of Chinese Academy of Medical Sciences was presented. Surgical approach feature of invaded the different position of skull base, selects the best operative access for safely removes the tumor, protects the critical structure of skull base as fully as possible, and decreases the complication were discussed in this article. RESULTS: Fourteen cases of benign and seventy cases of malignant underwent surgery. The tumor in 38 cases implicated parapharyngeal space and skull base. The lesion synchronously involved the anterior and middle cranial fossa in 7 cases, middle and posterior cranial fossa in 13 cases, lateral cranial base in 26 cases. The survival rate at 3 years was 68.5% (27/40) for malignant tumor. There was no operative death and severe complication in this series. CONCLUSION: To select the best operation access should think over following factors: 1. Tumor position and the scope implicated. 2. Safely and fully removal of the tumor. 3. The limited destroy to normal function structure and receivable cosmetic effect. 4. It is convenient to reliable reconstruction.

[Effect of salvagy surgeries for nasopharyngeal carcinoma].

OBJECTIVE: To explore a reasonable surgical method for improving salvagy surgery of nasopharyngeal carcinoma (NPC). METHOD: 25 cases of nasopharyngeal carcinoma with salvagy surgery were reviewed. Surgical accesses include the transcervico-mandibuio-palatal, the maxillary swing approach, the transpalatal approach for removing nasopharyngeal lesion. The pectoralis major muscle flap and galea aponeurotica flap were employed to repair operative defect and protect the critical structure of parapharyngeal space and the skull base. RESULT: The operative complication rate is 16% (4/25), which are local infection and flap putrescence. The postoperative sequela such as cleft palate is slight. 18 cases were followed-up over 3 year and 8 cases died. 2 cases were lost. The 3-year survival rate is 44% (8/18). CONCLUSION: The best operation access should be selected depending on the position and the implicated scope. Safely and fully removal of the tumor and reliably reconstruct are necessary. It is possible to improve salvage surgery effect for NPC patients.
