Prophylactic antibiotic use in clean, uncontaminated neck dissection.

A recent report in the literature cites a 10% wound infection rate for clean, uncontaminated neck dissections in patients who did not receive antibiotic prophylaxis as compared with a 3.3% infection rate in patients who received prophylactic antibiotics. Although a trend favoring antibiotic prophylaxis was identified, the duration of therapy was not considered. The present analysis addresses this issue. The authors retrospectively reviewed the records of 120 patients who underwent clean, uncontaminated neck dissections over a 3-year period (July 1989 through May 1992) for variables related to wound infections. Radiation therapy had previously been used in 70% of these patients. Group 1 (31 patients) received 24 hours of perioperative antibiotic prophylaxis, and group 2 (89 patients) received antibiotic prophylaxis until the suction drains were removed (usually 4 or 5 days after surgery). No perioperative wound infections occurred in either group. The authors concluded that perioperative antibiotic prophylaxis for 24 hours is sufficient to prevent wound infections in clean, uncontaminated neck dissections.

Traumatic neuroma after neck dissection: CT characteristics in four cases.

BACKGROUND AND PURPOSE: Traumatic neuroma, an attempt by an injured nerve to regenerate, may present as a palpable nodule or an area sensitive to touch (trigger point) after neck dissection. The purpose of this study was to identify CT characteristics of traumatic neuroma in four patients after neck dissection. METHODS: Between April 1995 and November 1998, the CT studies in three men and one woman (ages, 45-64 years) who had had a radical neck dissection and a nodule posterior to the carotid artery were reviewed retrospectively. CT was performed 1.5 to 6 years after neck dissection with clinical correlation and/or pathologic examination. Three patients had squamous cell carcinoma of the upper aerodigestive tract and one had a primary parotid adenocarcinoma. RESULTS: Three patients with a traumatic neuroma had a centrally radiolucent nodule with peripherally dense rim and intact layer of overlying fat, which was stable on CT studies for 1 to 2 years. One of these had a clinical trigger point. The fourth patient with a pathologically proved traumatic neuroma mixed with tumor had intact overlying fat, but the nodule lacked a radiolucent center and was not close to the carotid artery. CONCLUSION: The CT findings of a stable nodule that is posterior but close to the carotid artery with central radiolucency, a dense rim, and intact overlying fat, combined with the clinical features of a trigger point and a lack of interval growth, strongly suggest the diagnosis of traumatic neuroma.

Prophylactic neck dissection in squamous cell carcinoma of oral tongue: a prospective randomized study.

This paper presents the first report of an ongoing prospective randomised clinical trial in early T1T2N0 carcinoma of the oral tongue. The problems of regular follow-up in an indigent population from the vast rural expanse of India has been successfully overcome in this trial by close personal follow-up. The trial addresses itself specifically to prophylactic vs. therapeutic surgical management of the neck in T1T2N0 patients with cancer of the oral tongue. Overall disease, free survival (median follow-up 22 months) is higher (64% vs. 47%) in the group receiving prophylactic neck dissection. Disease-free survival for those with positive nodes at prophylactic neck dissection was twice that of those who underwent a subsequent therapeutic neck dissection (57% vs. 28%). Contralateral neck node metastasis has been identified as a significant factor in neck failures in those patients undergoing simultaneous prophylactic neck dissection.

[Effectiveness of therapeutic (NI, N2) modified radical neck dissection (MRND) in patients with laryngeal cancer].

OBJECTIVE: Efficacy of modified radical neck dissection in treatment of laryngeal cancer with node positive neck. PATIENTS AND METHODS: Retrospective analysis of 311 patients treated with modified radical (86) or radical (225) neck dissection. Recurrence rates, local and regional, after both operations and 5-year disease free survival (Kaplan-Meier method) were analyzed. RESULTS: Regional recurrence rates in N1 group after MRND were 3% and 13% after RND. In N2 group 13% and 16% respectively. 5-year survival after MRND in N1 group was 73% compared with 60% after RND. In N2 group 5-year survival was 56% and 47%. CONCLUSION: We consider MRND as effective treatment method of node positive neck in N1 and N2 stage compared to RND with less morbidity.

Anatomy and blood supply of the lower four cranial and cervical nerves: relevance to surgical neck dissection.

This study is a continuation of previous work searching for possible anatomic reasons to explain variable and usually unpredictable postoperative pain and dysfunction after the same nerve losses with similar neck dissection operations. The study consisted of dissections of 19 deceased unpreserved elderly subjects arterially injected with dyed latex. Of the 19 subjects, 14 had brain stem and cervical spinal cord dissections, and all had neck dissections. The findings suggested two possible anatomic reasons for the pain and dysfunction: (i) The intracranial anatomy of the lower four cranial nerves, the glossopharyngeal (IX), the vagus (X), the spinal accessory (XI), and the hypoglossal (XII), was just as variable as the previously reported peripheral spinal accessory nerve plexus; and (ii) Both the intracranial and neck dissections indicated that the blood supply to the lower four cranial and cervical nerves, particularly to the brachial plexus, could be impaired by atherosclerosis and/or neuroforaminal impingement or operative loss. This loss of blood supply theoretically could result in ischemia as another possible cause of postoperative pain and dysfunction. It is concluded that because of the potential importance of each nerve and vessel, often unknown at operation, it is very important to spare as many of them as possible to avoid subsequent painful impairment.

[Surgical anatomy and preservation of the accessory nerve in radical functional neck dissection].

OBJECTIVE: The surgical anatomy and preservation of the accessory nerve in radical functional neck dissection were studied. METHODS: Thirty-three cN(0) patients with oral cancers were entered into the study. Radical functional neck dissection were performed and the relations between the accessory nerve and its surrounding structures were recorded. RESULTS: The accessory nerve going through or beneath the sternocleidomastoid muscle occurred in 82% (27/33) and 18% (6/33) of the patients respectively. Communicating branches between the accessory and the cervical nerves were found in 85% (28/33). There was 2 to 3 cm of the accessory nerve paralleled to the anterior border of the trapezius muscle before it entered the muscle in 70% (23/33). The dissection of the nerve needed 20 to 30 minutes. Twenty-seven percent of the patients had pathologically proved lymph node metastases. CONCLUSIONS: Looking for accessory nerve under the upper portion of the sternocleidomastoid muscle and above the middle point of the muscle posterior border is simple and safe. The point of the great auricular nerve going out the muscle is an important indicator for finding the accessory nerve.

Supraomohyoid neck dissection. Is it diagnostic or therapeutic?

BACKGROUND: The supraomohyoid neck dissection (SOHND) is often performed in patients with cancer of the oral cavity, where there is no clinical or radiologic evidence of regional metastases. When on pathologic examination positive neck nodes are found, however, some consider it a curative operation, whereas others regard it as a staging procedure only. METHODS: We retrospectively reviewed 43 patients with cancer of the oral cavity who had a SOHND during the period from 1991 to 1994. All patients were staged as having N0 disease and had a total of 48 SOHNDs (38 unilateral, 5 bilateral). The follow-up period was at least 2 years. RESULTS: Seven of 48 N0-staged necks showed occult metastasis (15%). Two of these patients received postoperative radiotherapy. One of 7 (14%) patients with pathologic node-positive disease on the SOHND side developed recurrent ipsilateral neck disease during the follow-up period, whereas 4 (10%) recurrences developed in 41 necks that were pathologically staged as N0. Survival was 88% for patients with pathologically N0 necks versus 86% for patients with pathologically N+; disease. CONCLUSION: Supraomohyoid neck dissection is an effective staging procedure; however, in this group of patients, neck recurrence and patient survival after SOHND appear not to be related to pathology N stage. Also, SOHND with or without adjuvant radiotherapy appears to control the neck in the majority of patients, attesting to therapeutic efficacy. A prospective study is needed, however, to see if a "wait and see" policy does not achieve similar long-term outcome.

Neck dissection and combined therapy. Study of effectiveness.

Data on 1,385 neck dissections in 1,192 patients were studied to evaluate the effectiveness of treatment with operation alone and with various forms of combined therapy in controlling cervical metastasis. Of the 1,192 patients, 837 were treated by operation (neck dissection) alone, and the remainder had preoperative or postoperative radiation to the primary site and to the entire side of the neck that was dissected. In no stage of neck disease was either form of combined therapy superior to operation alone in decreasing the rates of recurrence. In an attempt to simulate a randomized, prospective study in a clinical situation for which the end results were already known, we used a separate statistical analysis--a case-control technique to specifically address the issue of the effectiveness of postoperative radiation in decreasing the frequency of recurrences after dissection in the various stages of disease. No evidence of a relationship between recurrence and the administration of planned postoperative radiation was found.

Excision level and indication for contralateral neck dissection in hypopharyngeal cancer surgery.

Margins of extirpated specimens of hypopharyngeal cancer were examined histopathologically. Residual cancer nest, which is most likely due to directional preponderance of the submucosal lymph flow of the hypopharyngeal cavity, was characteristically demonstrated at the superior margin and in the submucosal layer. We propose that laryngopharyngectomy be done at the extended excision level superiorly at the base of the palatine tonsil and inferiorly at the level of the 2nd thoracic vertebra and with a safety margin of at least 2 cm. The incidence of ipsilateral and contralateral neck metastasis was also histopathologically evaluated from specimens obtained by neck dissection. Contralateral neck metastasis was histopathologically confirmed in more than 30% of the cases examined and showed a difference in incidence related to histological differentiation and T classification. We conclude that bilateral neck dissection is advisable in all cases of hypopharyngeal cancer except for patients with a well-differentiated T2 lesion.

Anterior ischemic optic neuropathy following neck dissection.

BACKGROUND: Ischemic optic neuropathy (ION) is a rare but devastating complication of surgery. It has traditionally been associated with intraoperative hypotension in patients with underlying arteriosclerosis. METHODS: We present a case of ION following bilateral neck dissections in which there was minimal intraoperative hypotension and preservation of both internal jugular veins. The potential etiology of this disease is discussed along with a review of the literature. RESULTS: Five cases of ION following neck dissection have been documented. This complication is associated with the combination of intraoperative hypotension and anemia in the setting of prolonged bilateral neck dissection. Treatment is supportive, and final visual prognosis is variable. CONCLUSIONS: Ischemic optic neuropathy following neck dissection is best avoided by intraoperative blood pressure and anemia management. When it does occur, supportive therapy must be given. Final visual outcome is variable.

Modified and complete neck dissection in the treatment of squamous cell carcinoma of the head and neck.

The relative merits and indications for complete or modified dissection of the neck are straightforward. Which operation is selected centers on the perception of the value of the preservation or the risk with the loss of one or more of three structures: the spinal accessory nerve, the internal jugular vein and the sternocleidomastoid muscle. If these were the only issues, the choice of operation would be easy. Unfortunately, some of the most contentious issues in treatment of metastasis to the neck have been linked with the concept of the modified neck dissection. Such issues as combined multimodality therapy, preoperative and postoperative radiation therapy or surgical treatment alone, prophylactic dissection and bilateral simultaneous dissection of the neck are rightly or wrongly tied in with the type of dissection of the neck. More information, such as the certainty of the real risk factors in the neck with metastatic disease, the real value, if any, of adjunctive combined therapy and basic information about the role of the nodes in the neck, is necessary before the debate on the modified versus the radical dissection of the neck will end.

Avoiding complications in radical neck dissection.

As reported previously, it remains our conclusion that the radical neck dissection can be performed expediently in a reasonable period of time, usually without the need of blood replacement, and is not characterized by major physiologic disability or wound complications secondary to the neck dissection alone. The presence of preoperative radiation, composite resections entering the oral cavity or pharynx, and systemic disease or debilitation, however, vastly enhance the risk of significant life threatening complications and prolong hospitalization; therefore, the use of postoperative radiation therapy in combined treatment, the use of planned fistulas and generally accepted reconstructive techniques, and a careful evaluation of the methods and technique for protection of the carotid artery are recommended.

Supraomohyoid neck dissection in cancer of the oral cavity.

BACKGROUND: In oral cavity cancer, supraomohyoid neck dissection (SOHND) is becoming more popular for patients with N0 and N1 disease in the neck. The aim of this study was to assess the value of this surgical procedure. METHODS: The study included 237 previously untreated patients with oral cavity cancer. The neck treatment consisted of SOHND or functional neck dissection (FND). One hundred sixty patients underwent postoperative radiation therapy. Survival probabilities, neck recurrences, and distant metastases were analyzed according to the surgical procedure. RESULTS: For patients having undergone SOHND, the 5-year survival probabilities were 70.2% and 76.5% in N0 and N1 necks, respectively. The neck recurrence rate in SOHND was 2%. CONCLUSIONS: SOHND is an effective method of treatment for the clinically negative neck in patients with squamous cell carcinoma of the oral cavity. It also proves efficient, in conjunction with postoperative radiotherapy, for control of neck metastases in selected patients.

Occupational therapy for accessory nerve palsy after radical neck dissection.

The subjects in this study were ten patients with accessory nerve palsy after radical neck dissection. All the primary diseases that accounted for radical neck dissection were malignant tumors located at the head or neck. Every patient received occupational therapy and underwent evaluations before and after the therapy. The data we collected included the existence of resting pain and motion pain, and the active and passive range of motion during shoulder flexion and abduction. The occupational therapy programs were not adequately effective for resting and motion pain, however, every patient gained independence for activities of daily living and housekeeping activities. The occupational therapy significantly improved the patient's shoulder elevation in all movements; although, the active abduction was always significantly poor compared with flexion. In the meantime, there were no significant differences between passive shoulder flexion and abduction at all times. We can therefore understand that the accessory nerve palsy especially affects active shoulder abduction induced by the trapezius paralysis. Occupational therapy is an effective treatment for the improvement of shoulder function, however, the occupational therapy has limited effectiveness for coping with the pain.

Seroma prevention using fibrin glue during modified radical neck dissection in a rat model.

Seroma is a frequent sequelae of neck dissection involving cervical lymphadenectomy. The incidence is correlated with flap elevation, lymphovascular interruption, and tissue removal. Current methods of resolving seroma, such as vacuum drainage, are not risk free. A novel approach to this problem was the use of intraoperative topical fibrin glue. A model producing seromas was developed by modified radical neck dissection on Sprague-Dawley rats. Forty rats underwent this procedure. Twenty rats were treated with saline solution (control group) and 20 were treated with fibrin glue. At necropsy on day 5, a significant reduction in the frequency of seroma was noted in the fibrin glue group. Seventeen of 20 control rats had seroma whereas only 2 of 20 experimental animals had serous collection. The Fisher exact statistical correlation revealed p less than 0.000002; therefore, the use of fibrin glue in this role merits further evaluation.

Role of prophylactic antibiotics in uncontaminated neck dissections.

The use of perioperative prophylactic antibiotics in uncontaminated head and neck surgery remains controversial. We performed a retrospective analysis of 192 patients undergoing uncontaminated neck dissections from 1976 to 1989. Wound infection developed in 10% (10/99) of patients who did not receive antibiotics, while only three (3.3%) of 93 patients who received antibiotics developed infections. This difference was not statistically significant. We correlated the use of flaps, length of surgery, prior radiation treatment, and postoperative complications with rate of wound infection. The difference was not statistically significant for any of these variables. Our beta error was, however, greater than 0.2. Our data do not demonstrate efficacy of prophylactic antibiotics in uncontaminated neck dissections with statistical significance; however, a trend exists suggesting its possible value.

Thirty-year experience with 457 radical neck dissections in cancer of the mouth, pharynx, and larynx.

A retrospective analysis of 457 radical neck dissections (RNDs) performed for epidermoid cancers of the head and neck was performed. There was a 27 percent overall neck recurrence rate, 17 percent being confined to the neck. Only 5 percent occurred in the ipsilateral dissected neck. Failure in the neck correlated well with the node stage at the time of surgery, but was not affected by the size of the primary tumor, the timing of the RND, or the type of RND performed. Treatment of neck recurrences was predominantly surgical, with a 56 percent local control and a 24 percent disease-free survival rate. Overall disease-free survival was 53 percent, ranging from 68 to 29 percent according to the node stage. Survival was further affected by the size of the primary tumor and failure to control disease in the neck; it was not affected by the type of RND or its timing, or the addition of radiotherapy. Overall recurrence after modified RND was 28 percent. Increased neck recurrences were noted only in N2 and N3 cases, although survival was not affected even in these late stages.
