- چکیده انگلیسی: Introduction:
During functional neck dissection, the surgeon tries to preserve the internal jugular vein (IJV); however, the incidence of its narrowing or obstruction following modified radical neck dissection (MRND) or selective neck dissection (SND) varies between 0% and 29.6%. The most distressing complication of IJV thrombosis (IJVT) is pulmonary embolism. This study aimed to evaluate the incidence of IJVT following selective or modified radical neck dissection.
Materials and Methods:
In this study, 109 neck dissections were performed with the preservation of the IJV on 89 patients from March 2011 to December 2012 in the Cancer Institute of Imam Khomeini Hospital Complex, Tehran, Iran. Ultrasound evaluation of the IJV was performed in the early postoperative period and three months after the surgery.
Results:
The study population consisted of 62 male and 27 female patients with a mean age of 57+17.57 years. Ultrasound evaluation of the IJV among the participants (109 veins) indicated thrombosis in nine veins (8.25%) in the early postoperative period, four of which remained thrombotic and without flow three months after the surgery. Moreover, 96.33% of the IJVs were patent with a normal blood flow three months after the neck dissection. Among the evaluated IJVs, the only factor that showed a significant association with IJVT was the incidence of postoperative complications, including hematoma and seroma (P=0.01).
Conclusion:
It seems that the most important factor for the prevention of the IJVT is a meticulous surgery and surgical complication avoidance during neck dissection.- انتشار مقاله: 25-05-1396

- چکیده انگلیسی: Introduction:
To assess the rate of cervical lymph node involvement in patients with supraglottic squamous cell carcinoma (SCC) with no lymph node in clinical assessments and radiological studies.
Materials and Methods:
Fifty-six patients who underwent elective dissection of the cervical lymph node of the second through fourth level were enrolled, and pathologic evaluation of the dissected lymph nodes was performed. Lymph node involvement and association between tumor grade, smoking and gender with lymph node involvement were assessed.
Results:
The rate of the occult neck metastasis in this series was 37.5%. There was no statistically significant association between lymph node involvement and tumor grade, smoking, or gender.
Conclusion:
Based on the results of our study, we recommend elective bilateral neck dissection in all stages of N0 supraglottic SCC patients.- انتشار مقاله: 01-07-1395

- چکیده انگلیسی: Introduction:
Otorrhea and granulation tissue in Canal Wall Down mastoidectomy (CWD) is the common problem in cholesteatoma removal and leads to many discomfort for both the patient and the physician. The main objective in CWD is creating the dry cavity, so the topical antibiotic and acetic acid in variable saturations are used for this purpose. In this study we evaluate the effectiveness of topical MMC and chemical cautery by acetic acid.
Materials and Methods:
Study population consists of 50 patients with cholesteatoma whom underwent CWD. All patient allocated randomly in two study groups, MMC and acetic acid. After 3 weeks, the first visit is planned, extension of granulation tissue and dryness of cavity are evaluated and topical drugs are used in blind fashion. MMC in 4% and acetic acid in 12.5% saturation are applied. Other visits are completed at next month and 3 months later.
Results:
Both methods are effective in treatment of granulation tissue. In each group both treatment were effective too but MMC was more effective than acid acetic in the treatment of granulation tissue after 4 weeks.
Conclusion:
Based on our findings, it is clear that topical MMC is very effective in the treatment of granulation tissue and in CWD. It results in dry cavity much better than acetic acid without any complication.- انتشار مقاله: 19-03-1391

- چکیده:
- چکیده انگلیسی: Introduction: Reconstruction surgeryfor head and neck cancers restore patients’ function and appearance. Careful selection of flap for reconstruction of a defect after an ablative surgery can be a complex process and may affect on quality of life (QOL) of the patients. This study aimed to compare the quality of life between free and pedicle flap reconstruction groups in head and neck neoplasm patients.
Methods: This was a cross-sectional study of QOL in patients withhead and neck neoplasm that attend follow-up clinics from July to September 2019. All patients that underwent reconstructive surgery with either pedicle or free flaps were included in the study. At least 6 month-time was elapsed from the reconstructive surgery. QOL of the patients was evaluated using Medical Outcomes Study Short Form (MOS SF-36) questionnaire. The patients’ demographic data and medical history were collected using electronic patients’ records.
Results: Seventy patients completed the questionnaire. Forty one (58.57%) patients underwent pedicle and 29 (41.43%) patients free flap reconstructive surgery. There was no significant difference between pedicle and free flap groups with regard to age, gender, radiotherapy or chemotherapy (P>0.05).
The present study indicates that there was no statistically significant difference between pedicle and free flap groups with regard to 8 domains of SF-36 questionnaire (P>0.05), neither was significant difference between two groups with regard to the physical or mental component summaries (P>0.05).
Conclusion: The present study on quality of life of head and neck neoplasm patients that had undergone pedicle or free flaps showed no significant difference between two groups.- انتشار مقاله: 14-06-1398

- چکیده:
- چکیده انگلیسی: Introduction: The non-recurrent laryngeal nerve (NRLN) is an infrequent variant of inferior laryngeal nerve that takes an unusual course. Since this is a rare anatomic variation, operations on these patients carry a great risk of laryngeal nerve injury.
Case Presentation: A 25-year-old woman with papillary thyroid carcinoma and cervical lymphadenopathy underwent total thyroidectomy and bilateral neck dissection levels II – VI. It was noted intraoperatively that right inferior laryngeal nerve was a NRLN and right common carotid artery originated directly from the aorta and right brachiocephalic artery was absent. The nerve was preserved and patient underwent an uneventful surgery. She was well in her follow-up visits, her voice was good and both of her vocal cords were mobile on indirect laryngoscopy examination.
Conclusion: Although NRLN is a rare anatomic variation, surgeons should always think twice about this finding whenever right recurrent laryngeal nerve cannot be found according to anatomical landmarks intra-operatively.- انتشار مقاله: 17-05-1398

- چکیده:
- چکیده انگلیسی: Objective(s): In patients with papillary thyroid cancer (PTC), sentinel lymph node (SLN) radio-guided biopsy is not routinely used for detection of involved neck lymph nodes (NLN); 99mTc- antimony sulfide colloid (99mTc- ASC) has been used for this purpose. In this study, besides 99mTc-ASC another radiotracer, 99mTc-phytate (99mTc-P) with different doses and injection methods were evaluated.
Methods: Twenty-two patients, scheduled to undergo thyroidectomy for PTC, were injected for radio-guided SLN biopsy in the morning of operation in 3 groups: intra tumoral injection of about 1 mCi 99mTc-P (group A; n=5); peritumoral injection of less than 3 mCi 99mTc-ASC (group B; n=6); and peritumoral injection of 3 to 5 mCi 99mTc-ASC with application of massage (group C; n=9). A patient refused to complete the study. A patient with follicular thyroid cancer was also excluded. No NLN was detected in the pre-operative ultra-sonographic examinations of all patients. Central neck dissection was done for all the participants. The presence of radio guided detected NLN and results of pathology were assessed.
Results: In group A and B, no SLN was detected. NLNs were resected in 4 patients in group A and B; 2 of them involved by the tumor. In group C, 6 out of 9 patients (66.7%) had between 1 to 6 SLNs; the procedure failed to detect NLN in a patient in group C with surgically resected reactive NLN (failure rate 1 out of 7). Conclusion: The results underscored the significance of SLN radio guided biopsy in patients with PTC; the radiotracer, dose and method of injection may affect the detection rate.- انتشار مقاله: 04-05-1399
