Methods We retrospectively analyzed the clinical manifestations, signs, preoperative and postoperative management, and the treatment outcome of five patients with symmetric lipomatosis hospitalized in the Department of Otolaryngology-Head and Neck Surgery of West China Hospital between March 2004 and October 2010. Results All the five patients are male with a large quantity of subcutaneous fat deposit in and around the neck. Among them, one patient demonstrated extending upper thorax mass in the form of symmetrical apophysis; three experienced obstructive sleep apnea hypoventilation syndrome, and two had the symptom of snoring without apnea. Four patients had a long history of alcohol abuse with fatty liver, but had no liver dysfunction. In these four patients, one had alcoholism for many times. One out of the five patients had no history of alcohol abuse, but said to have been treated by a traditional Chinese medical technique GUASHA. All the patients underwent resection surgery, during which a large amount of noncapsulated white adipose tissue was confronted. The duration of follow-up lasted from three months to two years. There was one case of recurrence one year after the surgery and the patient refused re-operation. No obvious recurrence was found in the rest of the group. Conclusions Symmetric lipomatosis is a benign lesion characterized by diffused and symmetric accumulation of adipose tissue in the superficial or deep fascia space in the cervico-thoracic region. It mainly takes place in the middle-aged people. Long history of alcohol abuse and typical clinical manifestations can help to reach the diagnosis, but alcoholism may not be the only cause in etiology. Surgery may be the feasible therapeutic modality up to now.
Objective To summarize the current status of pedicled flaps for defect repair and reconstruction after head and neck tumor resection, and to present its application prospects. Methods Related literature was reviewed, and the role evolution of pedicled flaps in the reconstruction of head and neck defects were discussed. The advance, anatomical basis, indications, advantages, disadvantages, and modification of several frequently used pedicled flaps were summarized. Results The evolution of pedicled flaps application showed a resurgence trend in recent years. Some new pedicled flaps, e.g., submental artery island flap, supraclavicular artery island flap, submandibular gland flap, and facial artery musculomucosal flap, can acquire equivalent or even superior outcome to free flaps in certain cases. Technological modification of some traditional pedicled flaps, e.g., nasolabial flap, pectoralis major myocutaneous flap, latissimus dorsi musculocutaneous flap, temporalis myofascial flap, and temporoparietal fascial flap, can further broaden their indications. These traditional flaps still occupy an irreplaceable role, especially in patients with poor condition and institution with immature microsurgical techniques. Conclusion The pedicled flaps still plays an important role in head and neck reconstruction after tumor resection. In certain cases, they demonstrate some advantages over free flaps, e.g., more convenient harvest, more rapid recovery, less expenditure, and better functional and aesthetic effect.
ObjectiveTo evaluate the feasibil ity and effectiveness of suture ligation combined with super-wet tumescent technique to replace embolization before surgical resection of peri pheral arteriovenous malformations (AVMs) of the head and neck. MethodsBetween July 2007 and November 2010, 9 patients with peri pheral AVMs of the head and neck were treated, including 4 males and 5 females with a median age of 21 years (range, 8 months to 55 years). The causes were congenital malformation in 6 cases, trauma in 2 cases, and unknown origin in 1 case. The lesions were located at the frontotemporal region in 2 patients, cheek in 2 patients, occi pitocervical region in 2 patients, temporoparietal region in 1 patient, upper lip in 1 patient, and lower lip in 1 patient. The size of the AVMs lesions ranged from 2.2 cm×1.2 cm to 13.0 cm×10.0 cm. Of 9 cases, 8 were classified as Schobinger gradeⅡand 1 as gradeⅢ. The AVMs involved 2 to 7 main nutrient arteries, with a diameter range of 1.7-3.1 mm. At one-stage operation, AVMs was removed and direct suture, skin graft or flaps were used for repair in 6 cases; the skin was expanded at one-stage operation, and then AVMs removal and repair were performed at twostage operation in 3 cases. Before resection of AVMs, No.7 silk suture was used to l igate the main nutrient vessels, and then annular interrupted suture of soft tissue was performed with the silk sutures around the lesions, at least two rings. Tumescent anesthetic solution was injected into lesions, and super wet end-point achieved. ResultsPartial incision dehiscence occurred in 1 patient; the flaps and grafting skin survived, and primary healing of incision was obtained in the other patients. The mean operation time was 136 minutes (range, 42-367 minutes). The mean intraoperative blood loss was 268 mL (range, 15-1 000 mL). Only 1 patient received 3 units of blood transfusion. All patients were followed up for 4.2 years on average (range, 2 years to 6 years and 6 months); there was no recurrence case. The self-assessment cosmetic results were excellent or good in 5 cases and fair in 4 cases. ConclusionIntensive suture ligation followed by super-wet tumescent techniques might partially substitute preoperative embolization to facil itate surgical resection of peri pheral AVMs of the head and neck, due to simple operation and less bleeding.
ObjectiveThis study aimed to identify independent risk factors for head and neck squamous cell carcinoma (HNSCC) based on the surveillance, epidemiology, and end results (SEER) database and to develop a nomogram model for predicting patient survival outcomes. MethodsPatients diagnosed with HNSCC from 1975 to 2021 were selected from the SEER database. After applying inclusion and exclusion criteria, 2 271 patients were included and randomly divided into a training cohort and a validation cohort in a 7∶3 ratio. Independent prognostic factors were identified using LASSO regression, Cox regression analysis, and the Akaike information criterion (AIC). A nomogram model was constructed, and its discrimination and calibration were assessed using the concordance index (C-index), time-dependent area under the curve (time-dependent AUC), and calibration curves. The nomogram model was compared with the American Joint Committee on Cancer (AJCC) staging system using decision curve analysis (DCA), net reclassification index (NRI), and integrated discrimination improvement (IDI) to evaluate clinical utility and risk stratification performance. ResultsFive independent prognostic factors (age, marital status, N stage, tumor stage, and radiotherapy) were selected to build the nomogram model for HNSCC. The C-index values of the model were 0.731 4 (95%CI 0.714 5 to 0.748 5) in the training cohort and 0.735 1 (95%CI 0.709 1 to 0.761 0) in the validation cohort. The time-dependent AUC values were all above 0.7, indicating good discriminatory ability. Moreover, decision curve analysis showed that the nomogram model provided higher clinical net benefits at different threshold probabilities and performed better than the AJCC staging system in identifying high-risk patients. ConclusionThis study develops a nomogram model based on the SEER database to predict survival outcomes in patients with HNSCC. The model demonstrates high discrimination and clinical utility, offering a personalized prognostic tool for clinicians.
Objective To introduce the experience of the cl inical appl ication of vertical trapezius myocutaneous flap in repairing soft tissue defects after head and neck tumor resection. Methods Between June 2008 and February 2010, 12 cases of soft tissue defect caused by head and neck tumor resection were repaired with vertical trapezius myocutaneous flap.There were 9 males and 3 females with an age range from 32 to 76 years (median, 54 years). Twelve cases including 2 cases of basal cell carcinoma of orbital skin, 2 cases of squamous cell carcinoma of the parotid gland, 2 cases of submandibular gland mal ignant mixed tumor, 2 cases of metastatic lymph nodes of nasopharyngea carcinoma after radiotherapy, 1 case of squamous cell carcinoma of tongue, and 3 cases of squamous cell carcinoma of occipital skin, and all were classified as TNM stages T3 or T4. The area of soft tissue defect ranged from 13 cm × 6 cm to 25 cm × 13 cm. The vertical trapezius myocutaneous flap ranged from 14 cm × 7 cm to 26 cm × 14 cm and was transfered to repair defect tissue in the homolateral wounds after tumor resection and neck dissection homochronously. The donor sites were sutured directly. Results All incisions healed primarily without infection. Eleven flaps survived except 1 flap with edge necrosis, which was cured after dressing change. Subcutaneous hematocele and effusion occurred in 2 cases on the back after tube was removed at 7 days postoperatively, and they were cured by sucted and pressured dressing. Eleven patients were followed up 1-3 years (mean, 2 years). Nine cases had no tumor recurrence and the flaps had statisfactory appearance; the abduction function of shoulder joint were normal. One case of orbit basal cell carcinoma occurred 3 months after operation and 1 case of nasopharyngeal carcinoma died of brain metastasis 12 months after operation. Conclusion It is an easy and simple therapy to repair head and neck soft tissue defect using the vertical trapezius myocutaneous flap, which can meet the needs of repairing tissue defect of head and neck.
Objective To evaluate the efficacy and side effect of non-conventional fractionated radiotherapy for head and neck cancer.Methods Trials were identified by searching CENTRAL, MEDLINE, EMBASE, Chinese Biological Medicine Database (CBMdisc) and Chinese VIP Database. We handresearched the data from 10 kinds of important Chinese journals. Two reviewers assessed and extracted the studies. The following primary outcomes were assessed: complete relief (CR), overall survival (OS), acute side effect and late side effect. Results Twenty-three trials involving 8 411 patients were included. Thirteen trials were of good quality, and the rest were of poor quality. Meta-analysis of these trials showed that: (1) non-conventional fractionated radiotherapy vs conventional fractionated radiotherapy: ① Only S-HART and CAIR resulted in higher CR, RR=1.21 (95%CI 1.02 to 1.44), 3.31 (95%CI 1.16 to 9.42), respectively; ② Only HRT could improve 2-year OS (RR=1.32, 95%CI 1.13 to 1.54), but this difference wasn’t found in 5-year follow up; ③ Most of the non-conventional fractionated radiotherapy could increase acute side effects, but not the late ones; (2) non-conventional fractionated radiotherapy combined with concurrent chemotherapy vs non-conventional fractionated radiotherapy: ① Only C-HRT resulted in higher CR (RR=1.58, 95%CI 1.18 to 2.11); ② Higher 2-year OS could be gained when combined with chemotherapy (RR=1.35, 95%CI 1.18 to 1.54), and only C-HRT resulted in higher 5-year OS (RR=1.57, 95%CI 1.19 to 2.07). ③ Acute and late side effects of radiotherapy would not increase when combined with chemotherapy. Conclusion It can not be concluded that non-conventional fractionated radiotherapy can improve the CR and OS of head and neck cancer, for a small number of patients, but it will get effect when combined with concurrent chemotherapy, and would not increase acute or late side effects. The effects of HRT and C-HRT should be cared specially.
