Value of the supraomohyoid neck dissection with frozen section analysis as a staging procedure in the clinically negative neck in squamous cell carcinoma of the oral cavity.

A retrospective analysis was performed to evaluate with the efficacy of elective supraomohyoid neck dissection (SOND) with frozen section (FS) analysis in 57 newly diagnosed patients (62 SONDs) with squamous cell carcinoma of the oral cavity. The protocol included sampling of both the most suspect and largest node in the jugulodigastric region (if present) and the most distal jugulo-omohyoid lymph node (if present). These nodes were then studied with FS histological examination. In the absence of evident nodes for FS analysis during surgery, histological examination uncovered occult metastatic disease in 3 of 11 SOND specimens. Among the remaining patients FS analysis revealed occult metastatic disease in 10 of the 51 samples (19.6%). In these latter cases surgery was continued using standard or modified radical neck dissection en bloc with the primary tumor. In 1 specimen only a single metastasis was found outside the original extent of the SOND. Among 41 FS analysis reports stating the absence of metastatic disease, histological examination of the SOND specimens demonstrated occult nodal disease in 7 (17%). All of the cervical metastases appeared in the ipsilateral side of the neck. False FS reports did not occur. In the histologically proven absence of metastatic disease in the SOND specimens, disease recurrence in the neck occurred only in 3 cases (7%), all in the presence of local failure: once in the previous SOND area, once in the ipsilateral supraclavicular region and once on the contralateral side.(ABSTRACT TRUNCATED AT 250 WORDS)

Supraomohyoid neck dissection: rationale, indications, and surgical technique.

The supraomohyoid neck dissection is a selective cervical node dissection that removes the contents of the submental and submandibular triangles (lymph node level I), the jugulodigastric and jugulo-omohyoid lymph node groups, and the lymph node-bearing tissues located anterior to the cutaneous branches of the cervical plexus and above the omohyoid muscle (lymph node levels II and III). The sternocleidomastoid muscle, the spinal accessory nerve, and the internal jugular vein are preserved. This type of neck dissection is indicated in the surgical management of the neck in patients with large T2, T3, and T4 squamous cell carcinomas of the oral cavity in whom the cervical lymph nodes are either clinically negative (N0) or single, discrete, and less than 3 cm in diameter (N1). In this paper, we discuss the rationale for this operation, its staging, and its therapeutic value, and present a detailed description of the surgical technique.

[Bilateral chylothorax after radical neck dissection. Apropos of a case].

Bilateral chylothorax following radical neck dissection is an uncommon complication of head and neck surgery. Only 9 more cases have been reported in the English literature until now. Early recognition is not difficult if it is bear in mind when evaluating dyspnoeic patients with bilateral pleural effusions after neck dissection. In this paper the authors report their experiences with a case and comment on the treatment employed. The authors believe that due to its potential severity, it must be considered when ever head and neck surgery is performed.

Functional neck dissection. A description of operative technique.

The operative technique involved in functional neck dissection is described to clarify its stepwise execution. Recent interest in functional preservation demands therapeutic techniques that are oncologically reliable but not multilating. The functional neck dissection seems to be a reasonable alternative to radical radiotherapy and a preferred alternative to traditional neck dissection in the control of regional metastasis when disease in the neck is either occult of still confined to mobile lymph nodes.

Bilateral radical neck dissection.

From January 1960 to December 1977, 61 patients had a simultaneous one-stage bilateral neck dissection with or without excision of the primary lesion, while 63 patients had a therapeutic second (two stage) neck dissection performed by our service. In ten patients, one or both of the internal jugular veins and spinal accessory nerve were preserved. Patients in both groups were staged, using the American Joint Commission 1977 clinical classification. All the pathologic specimens had lymph node clearance done. Simultaneous bilateral neck dissection, in the present study, has an operative mortality of 10%, with 11% life-threatening complications and with 62% significant postoperative facial swelling. There is an overall three- and five-year survival rate of 20% and 12.5%. Patients who had bilateral staged neck dissection had complications seen in 54%, with a 3.2% mortality rate. The overall three- and five-year survival in this group of patients was 60% and 38%, respectively.

Cervical metastases following radical neck dissection that preserved the spinal accessory nerve.

In contrast to the original neck dissection technique, the spinal accessory nerve is routinely sacrificed in the so-called classical neck dissection. The benefit of this routine has never been documented; on the contrary, facts have accumulated that indicate that the nerve should be preserved. The results in this article serve to emphasize this opinion. Of 80 patients who underwent radical neck dissection that preserved the spinal accessory nerve, the potential for cure was not jeopardized in a single case.

Neck dissection for surgical treatment of lymphnode metastasis in papillary thyroid carcinoma.

In papillary thyroid carcinoma lymphnode metastases at presentation do not seem to adversely affect survival, but do increase the risk of loco-regional tumor recurrence. The value of systematic versus selective lymphadenectomy is far less standardized, whereas the role of postoperative radioiodine in preventing either nodal recurrence or cancer death remains controversial. Clinical data of 36 N+ patients with papillary thyroid carcinoma who had undergone from 1990 to 1996 ipsilateral or bilateral neck dissection were retrospectively reviewed, to analyse the value of systematic lymphadenectomy. In our series of 50 extensive lymph node dissections (levels 2-6), the number of metastases in each specimen (mean value: 5) and the incidence of multiple level metastases (36%) were high. In 37.5% of the metastases at level 6 and in 11.1% at level 4, coexisting nodal involvement at level 2 was observed, without metastasization at intermediate levels. Multiple levels metastases and skip metastases were present in at least one third of the patients and could be excised only performing a complete dissection of the levels 2-6. Extra-capsular spread was found in 56% of the specimens. In 64.3% of these cases a functional neck dissection was performed. A modified radical or radical neck dissection was carried out in the other 35.7% of the cases. These patients received modified radical neck dissection (functional dissection with sacrifice of internal jugular vein) in 60% of the cases and radical neck dissection in the other 40%. In papillary thyroid carcinoma extensive lymphnode dissection at presentation has been stated to offer no advantage versus selective lymphadenectomy, causing increased morbidity. However, experienced surgeons report a low incidence (less than 5%) of accessory spinal nerve and cervical plexus permanent sequelae after functional neck dissection. In our opinion, patients with cervical lymph node metastases require a complete loco-regional neck dissection. Systematic lymphadenectomy, performed by lateral neck plus upper anterior mediastinal dissection, can yield a high disease-free survival. Moreover, this can limit the overall radio-iodine therapeutic dose and the risk of de-differentiation of recurrent tumor to the anaplastic type in patients with a long-term and near normal life-span.

Reconstruction of spinal accessory nerve after radical neck dissection.

Resection of the spinal accessory nerve in cases of radical neck dissection often causes considerable damage to the function of the shoulder girdle; it leads to limitation of the motion of the upper limb and pain in the shoulder girdle. It seems a sensible compromise to reconstruct the spinal accessory nerve in one-stage operation with radical neck dissection, which can often prevent extensive atrophy of the trapezius muscle, with a resultant improvement in the chance of successful rehabilitation. The technique of the operation is described: after completion of radical neck dissection, in one-stage operation an autogenous nerve transplant from the n. auricularis magnus is sewn onto the central and peripheral stumps of the spinal accessory nerve, which are protected by a "vein-muff" and the fascia of the muscle. After such spinal accessory nerve reconstruction, subjective complaints and objective symptoms were much milder in 6 patients than in the control group, which consisted of 10 patients who underwent a similar operation but without spinal accessory nerve reconstruction.

Microsurgical neck dissection for occultly metastasizing medullary thyroid carcinoma. Three-year results.

BACKGROUND: Medullary thyroid carcinoma (MTC) metastasizes early into the regional lymph nodes, but distant metastases occur late. Modified radical neck dissection might improve the treatment results for occultly metastasizing MTC. METHODS: The authors report 23 patients after a minimal follow-up of 2 years (median, 36 months). There were 11 female and 12 male patients. The mean age was 43 years (+/- 13 years). The surgical technique included the meticulous dissection of all compartments of the neck, resulting in a unilateral or bilateral modified radical neck dissection with the complete removal of the lymphatic and fatty tissue between important anatomical structures. The surgical boundaries extended cranially to the mastoid, caudally to the brachiocephalic vein involving a transcervical mediastinal dissection, and laterally to the edge of the trapezoid muscle. Ten patients were treated bilaterally and 13 patients unilaterally. RESULTS: The basal calcitonin values of 18 of the 23 patients were postoperatively normalized with 4 patients having normal basal and pentagastrin-stimulated calcitonin levels. Five patients with persistently elevated basal serum calcitonin values had a marked reduction of the postoperative calcitonin levels compared with their preoperative concentrations. However, in these five patients histologic abnormalities precluded a surgical cure. The permanent complication rates were tolerable (4 of 33 neck dissections). CONCLUSIONS: The microsurgically extended neck dissection can reduce basal and pentagastrin-stimulated serum calcitonin values to normal levels even after long intervals following primary thyroidectomy.

Functional neck dissection for treatment of recurrent branchial remnants.

OBJECTIVE: To evaluate the role of functional neck dissection for treatment of cervical branchial remnants that are recurrent after previous surgical intervention. DESIGN: A retrospective review was undertaken of six patients undergoing functional neck dissection for excision of recurrent branchial anomalies treated over an 18-year period. SETTING: Academic tertiary referral medical center. PARTICIPANTS: Six patients with recurrent branchial cysts, sinuses, or fistulas. Each participant previously had undergone between one and 14 ineffective surgical procedures. INTERVENTION: Each patient was treated by functional neck dissection. OUTCOME MEASURES: Clinically noted complications and recurrences. RESULTS: There were no major complications. Minor complications included one postoperative wound infection and one transient spinal accessory nerve paresis. There were no recurrences. CONCLUSIONS: Functional neck dissection is a safe and effective procedure for surgical management of recurrent cervical branchial remnants.

Modified radical neck dissection. Terminology, technique, and indications.

The terminology relating to the various modifications of radical neck dissection is loose and confusing. A simple system of nomenclature has been suggested which allows specification of the node levels dissected and the structures preserved. A technique of modified neck dissection, which excludes dissection of the posterior triangle and spares the sternocleidomastoid muscle and spinal accessory nerve, has been described. We believe this operation is appropriate when local disease is advanced and clinically uninvolved neck nodes are likely to harbor occult metastatic disease, when resection of the primary tumor is through the neck, or when clinical disease in the neck is minimal. Patients with multiple palpable nodes, patients with nodes larger than 3 cm in diameter, patients with disease in the posterior triangle, and patients in whom radiotherapy to the neck has failed may be better served by radical neck dissection.

Neck dissection with or without postoperative radiotherapy in supraglottic carcinomas.

A retrospective review of 302 previously untreated patients with primary supraglottic carcinoma was undertaken to ascertain the efficacy of postoperative radiotherapy. The 302 patients underwent a total of 383 functional neck dissections and 45 classic radical neck dissections. Pathological examination revealed nodal involvement in 117 patients (39%). In the histologically N0 group, the incidence of contralateral neck recurrence when a unilateral neck dissection and postoperative radiotherapy were carried out was 8%, rising 21% when no postoperative radiation was given. There was no difference in the ipsilateral recurrence rate in the N0 group, radiated patients (3%) and nonradiated patients (2%). Similar figures were found in the N1 group. Bilateral functional neck dissection in histologically N0, N1, and N2 necks had similar recurrence rates with or without radiotherapy. Distant metastasis appeared in 10% of N0 patients and in 35% of N3 patients. Patients who received postoperative radiotherapy showed a significantly higher rate of distant metastasis (21%) than patients who did not (8%). The number of involved lymph nodes had no relevance both in neck recurrence and distant metastasis.

Recurrence of carcinoma of the oral cavity, oropharynx and maxillary sinus after radical neck dissection.

Cervical recurrence was studied in 63 patients who had undergone radical neck dissection for the treatment of carcinoma of the oral cavity, oropharynx and maxillary sinus. Over the whole series, recurrence occurred in 17 patients (27%). The rate of recurrence did not decrease in patients who remained free of carcinoma at the primary site, but was significantly lower in patients in whom elective neck dissection was performed than in those who were treated by therapeutic or secondary neck dissection. With the exception of two patients, cervical recurrence was associated with the presence of metastatic lymph nodes. Although the rate of recurrence was not affected by the number of metastatic lymph nodes, it was very high (80%) in patients having metastatic lymph nodes with histological evidence of extra-nodal spread. The results indicate that elective treatment by irradiation or surgery may be needed to reduce cervical recurrence because of a high tendency of carcinoma of the oral cavity and adjacent regions to metastasize.

Neck dissection with and without radiotherapy: prognostic factors, patterns of recurrence, and survival.

A group of 179 patients who had 205 neck dissections between 1979 and 1984 has been reviewed to assess the influence of adjuvant radiotherapy on survival. Lymph nodes were histologically involved in 91 of 107 radical neck dissections (85 percent) and 55 of 98 modified neck dissections (56 percent). Eighty-two patients received adjuvant radiotherapy of 5,000 rads or more. Patients with involved nodes had significantly lower survival rates than those with uninvolved nodes. Among patients with involved nodes, survival was significantly lower when two or more nodes were involved, when there was nodal involvement at multiple levels, or when extracapsular spread was present. Adjuvant radiotherapy was associated with a reduced recurrence rate in the ipsilateral neck but the incidence of distant metastases was higher. When patients with involved nodes were subgrouped according to prognostic factors, the survival of irradiated patients was improved only in the highest risk group, but this was not statistically significant. When radiotherapy is added to neck dissection for treatment of cervical metastases it can be expected to reduced ipsilateral neck recurrence and prevent relapse in the contralateral neck. Improved survival may depend on an ability to detect and treat occult distant metastases.

Impact of bilateral neck dissection on recovery following supraglottic laryngectomy.

Previously reported data from our institution has led us to perform bilateral neck dissections for therapeutic as well as staging advantages for horizontal supraglottic laryngectomies. Concern over the possibility of increased morbidity associated with simultaneous bilateral neck dissection prompted this retrospective review of patients with supraglottic laryngectomy who were treated with either unilateral (46 patients) or bilateral (23 patients) neck dissection. No significant differences were found in morbidity when patients were evaluated for transfusion rate, cervical wound drainage, need for tracheotomy, oral diet, or duration of hospitalization. Significant differences were noted in surgical operating time, eg, it took 100 minutes longer to perform bilateral dissections, and slight increases were noted in estimated blood loss and fluids given intravenously. No significant differences were noted in the percentage or type of postoperative complications. It seems that bilateral neck dissection in conjunction with supraglottic laryngectomy does not increase postoperative surgical morbidity and may actually avoid complications associated with postoperative radiation therapy in patients with supraglottic laryngectomy.

Radical neck dissection: is it enough?

This series of 307 patients who underwent radical neck dissection showed an overall recurrence rate of 19 percent. Clinical staging of disease was an accurate predictor of both recurrence and survival. Extranodal disease dramatically increased recurrence and decreased survival. Although our recurrence rate after radical neck dissection was lower than that previously reported for surgery alone, it was still significantly higher than that after adjuvant radiotherapy. We conclude that histologically proved neck disease should be treated by radical neck dissection, followed by adjuvant radiotherapy to decrease recurrence and, it is hoped, improve survival.

Modified radical neck dissection for metastatic carcinoma of the thyroid. A reappraisal.

From January 1958 through December 1983, 56 modified radical neck dissections were performed on 47 patients with metastases to the cervical nodes from differentiated carcinomas of the thyroid. In nine patients, a second modified radical neck dissection was performed either simultaneously or at a later date. Lymph node clearance was performed on all but one surgical specimen. The number of nodes in each specimen ranged from 10 to 96, and the number of involved nodes ranged from 1 to 20. Thirty-eight of the 56 neck specimens contained four or more positive nodes. Seventeen patients were followed for 10 to 26 years, 18 patients for 5 to 9 years, and 5 patients for less than 5 years. Seven other patients died, three from other causes and four from lung metastases. There were no recurrences in the neck sides that would have been cleared if standard radical neck dissection had been performed. This reappraisal with long-term follow-up supports our initial impression that a modified radical neck dissection sparing the spinal accessory nerve, the sternocleidomastoid muscle, the internal jugular vein, or any combination thereof is an effective procedure for differentiated cancer of the thyroid, with preservation of good shoulder function and improvement in the cosmetic appearance of the neck.

Modified neck dissection in treatment of thyroid cancer: a safe procedure.

Differentiated carcinoma of the thyroid metastasizes early and frequently to cervical lymph nodes. Radical neck dissection performed electively or therapeutically results in high cure rates. Modified neck dissection consisting of a single transverse incision, resection of the jugular chain of nodes and those in the posterior triangle of the neck with preservation of the sternomastoid muscle, the spinal accessory nerve and the submandibular salivary gland provides a cosmetic, functional result with minimal morbidity. In a series of 313 neck dissections for thyroid carcinoma, only three patients with papillary or follicular carcinoma, which was resectable, treated by thyroidectomy and modified neck dissection died of disease.
