Among them, 21 cases were given preoperative radiotherapy and surgery (R+ S). The radiation therapy dose was 45 Gy. And 14 cases′ larynx is preserved. In addition, 27 cases were given postoperative radiotherapy and surgery (S+ R). The radiation therapy dose was 65 Gy. And 10 cases had preserved laryngeal function. Survival rates were analyzed by the Kaplan-Meier method. Chi-square test was used to compare complications between two groups.@*Results@#The larynx preservation rate in R+ S group [66.7% (14/21)] was significantly higher than that in S+ R group [37.0% (10/27), P<0.05]. The complication rate and decannulation rate in R+ S group were 42.9% (9/21) and 64.3% (9/14), respectively, showing no difference compared with those in S+ R group [37.0% (10/27) and 50.0% (5/10), respectively] (all P>0.05). The complication rates of patients with and without larynx preservation were 41.7% (10/24) and 37.5% (9/24), respectively, showing no difference between two groups (P>0.05). The overall 3-years and 5-years survival rates for all patients were 54.2% (26/48) and 35.4% (17/48), respectively. There was no significant difference in survival rates between R+ S [38.1% (8/21)] group and S+ R group [33.3% (9/27), P>0.05)]. In the R+ S group, the survival rates in patients with and without larynx preservation were 40.0% (4/10) and 29.4% (5/17), respectively, showing no significant difference between two groups (P>0.05).@*Conclusions@#It is secure and effective to choose the operation with laryngeal preservation for patient over 70 years of age with medial wall pyriform sinus cancer based on their physical conditions and the tumor extension. The preoperative- and postoperative-radiotherapy have the similar effect. Preoperative radiotherapy and surgery increases the laryngeal preservation rate.

Diagnosis and surgical treatment of Madelung's disease / 中国耳鼻咽喉头颈外科

OBJECTIVE To discuss t he diagnosis and surgical methods of the Madelung's disease. METHODS Detailed clinical data of 6 patients with Madelung's disease who was received surgical treatment in our department from January 2011 to November 2015 were reviewed. RESULTS All patients were male, aged from 35 to 65 years. The 6 patients had excessive subcutaneous fat deposit predominantly around the neck. One of the 6 patients had excessive fat deposit in larynx. All patients had history of heavy drinking. Two patients had the complication of cardiac disease, pulmonary disease and cerebral disease. One patient had the complication of glucose intolerance. Five patients were associated with sleep apnea syndrome. One patient came to hospital with dyspnea in emergency. All patients had received surgical treatment and abstinence from alcohol, 4 patients had the total neck lipectomy and tracheotomy. One patient had the total neck lipectomy with no tracheotomy. One patient had received emergency surgery-partial neck lipectomy and tracheotomy because the patient came to hospital with dyspnea in emergency. This case was referred to respiratory department without a second surgery for his severe complications and high surgical risk. This case discharged with tracheal tube. No obvious recurrence was seen during a follow-up of 15 days to 48 months. The pathological results were nonencapsulated fat. CONCLUSION Madelung's disease is a kind of benign disease arised from lipodystrophy which characterized by massive accumulation of nonencapsulated subcutaneous fat mainly located symmetrically in the fascial space of neck and shoulder. Most patients had heavy drinking history, chronic alcoholism may be a major risk factor. It may be associated with some complications. Total neck lipectomy has good effect. The aim of the operation is to improve outline appearance and function of the neck, which is good for patient's quality of life.

The options of surgery and laryngeal preservation for hypopharyngeal cancer patients more than 65 years old / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the effectiveness of preserving laryngeal function for senile hypopharyngeal cancer patientsolder than 65.@*METHOD@#The clinical data of 58 surgery cases of senile hypopharyngeal cancer patients more than 65 years old were colleted and analyzed. Thirty-one cases preserved the laryngeal function, while the rest did not. Perfect preoperative preparation was done before surgery. Surgical resection specimens were sent to frozen-section examination. When the negative incisal margin was confirmed, the defect was repaired by the appilication of local stitching, ribbon muscle flap, major myocutaneous flaps, split thickness skin and replacement of esophagus by stomach. Radical radiotherapy was used after surgery. Survival rate was calculated by the Kaplan-Meier method. Chi-square test was used to compare complications of the two groups.@*RESULT@#The 3 years and 5 years survival rate for all cases were 48.3% (28/58) and 27.6% (16/58), respectively. For patients with laryngeal function preservation, the 3 years and 5 years survival rate were 51.6% (16/31), 29.0% (9/31), respectively. For cases without laryngeal function preservation, the 3 years survival rate and 5 years survival rate were 44.4% (12/ 27), 25.9% (7/27), respectively. The result showed no obvious difference in survival rate between two groups (P > 0.05). Surgery complication rate were 45.2% (14/31) and 40.7% (11/27), without obvious differences between the two groups (P > 0.05).@*CONCLUSION@#It is feasible for senile hypopharyngeal cancer patients to choose suitable operation based on their physical conditions and the tumor extension. The key issues include well perioperative treatment management, correct indications grasp, and intraoperative repair skills improvement.

OBJECTIVE@#To systematically evaluate the efficacy and safety of harmonic scalpel in neck dissection.@*METHOD@#Available literatures of PubMed, EMBASE, Cochrane Library, Google Scholar, CBM, CNKI, WangFang and VIP published before June 2014 were searched. Inclusion criteria and quality assessment were performed. All data were analyzed by using RevMan 5.2 software.@*RESULT@#Fourteen studies including 632 cases were enrolled. Among them, 319 cases were in harmonic scalpel group and 313 cases in conventional resection group. Compared with conventional resection group, the harmonic scalpel group showed shorter surgery time(weighted mean difference [95% confidence intetval]: -28.01 [-36.83, -19.19], Z = 6.22, P < 0.01)and less intra-operative blood loss (weighted mean difference [95% confidence intetval]: -46.68 [-57.25, -36.12], Z = 8.66, P < 0.01). The number of cervical lymph nodes dissected and the incidence of postoperative chylous leakage were similar in both groups.@*CONCLUSION@#Using the harmonic scalpel in neck dissection was as efficient and safe as that of the conventional technique with the advantage of shorter time of surgery and less intraoperative blood loss.

Laryngeal function preserving surgery in elderly hypopharygeal carcinoma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the indications and the effective treatment methods of laryngeal function preserva tion in aged patients with hypopharyngeal carcinoma.@*METHOD@#Clinical data about 41 patients with hypopharygeal carcinoma were analysed. These patients were more than or equal to 60 and were treated from January 2006 to December 2011. Among them, 25 cases were treated with laryngeal functions preserved and the hypopharynx defect was immediately re paired by the adjacent tissue flap or (and) the pactoralis major myocutaneous flap according to the size of defect after tumor resecting. The survival rate was calculated by Kaplan-Meier method.@*RESULT@#In 25 patients with laryngeal function preservation, 16 cases were 60-69 years old, 6 cases were 70-79 years old and 3 cases were 80-88 years old. The tumour located at lateral wall of pyriform sinus in 14 cases, at anterior wall of pyriform sinus in 3 cases, at inside wall of pyriform sinus in 3 cases, at upper side wall of hypopharynx invading tonsil or tongue base in 3 cases, at posterior hypopharyngeal wall in 2 cases. The average length of post-operation stay was 22.2 days. Eight cases suffered from post-operative complications (32%), including of pharyngeal fistula in six cases and pulmonary infection in two cases. The respiratory function and pronunciation were all restored, in 25 cases, among which 20 cases removed tracheostomy tube about 3 months after surgery. 2 cases were missed after 1-year followed up. 2 cases died of local tumor recurrence. 4 cases died of neck recurrence. 8 cases died of pulmonary matastasis. The 1-year and 3-year survival rate of the disease in the group was 67.5% and 43.9% respectively.@*CONCLUSION@#As the aged cases of hypopharygeal carcinoma are choosed appropriately and repaired feasibly, surgery for the disease with laryngeal function retention may be safe and effective.
