No full textSubmandibular space infection: a potentially lethal infection.
No full textOBJECTIVES: The aims of this study were to review the clinical characteristics and management of submandibular space infections and to identify the predisposing factors of life-threatening complications.
DESIGN AND METHODS: This was a retrospective study at a tertiary academic center. We retrieved and evaluated the records of all patients admitted to the University of Padua Otolaryngology Clinic at Treviso Regional Hospital with the diagnosis of submandibular space infection for the period 1998-2006. The following variables were reviewed: demographic data, pathogenesis, clinical presentation, associated systemic diseases, bacteriology, imaging studies, medical and surgical treatment, and complications. A multivariate logistic regression analysis was undertaken using a forward stepwise technique.
RESULTS: Multivariate analysis identified four risk factors for complications. Anterior visceral space involvement (odds ratio (OR) 54.44; 95% confidence interval (CI) 5.80-511.22) and diabetes mellitus (OR 17.46; 95% CI 2.10-145.29) were the most important predictive factors in the model. Logistic regression analysis also confirmed other comorbidities (OR 11.66; 95% CI 1.35-100.10) and bilateral submandibular swelling (OR 10.67; 95% CI 2.73-41.75) as independent predictors for life-threatening complications.
CONCLUSIONS: Airway obstruction and spread of the infection to the mediastinum are the most troublesome complications of submandibular space infections. Therefore, the maintenance of a secure airway is paramount. Patients with cellulitis and small abscesses can respond to antibiotics alone. Surgical drainage should be performed in patients with larger abscesses, Ludwig's angina, anterior visceral space involvement, and in those who do not respond to antibiotic treatment. Moreover, the clinical assessment in patients with comorbidities, especially diabetes mellitus, requires a high level of suspicion for potential life-threatening complications. Early surgical drainage should always be considered in these patients, even in seemingly less critical cases
Pattern of lymph node metastases in squamous cell carcinoma of the tonsil: Implication for selective neck dissection.
No full textThe aim of this study was to prospectively analyze the distribution of neck metastases and the outcome in patients surgically treated for tonsillar carcinoma in order to deduce implications for selective neck dissection. The criteria for inclusion in the study were (1) previously untreated, histologically proven, resectable squamous cell carcinoma of the tonsil, (2) curative surgical intent on the primary tumor and neck, (3) no history of prior head and neck cancer, (4) absence of synchronous second primary in the upper aerodigestive tract, lung and esophagus, (5) absence of distant metastases. Fifty-eight previously untreated consecutive patients with tonsillar squamous cell carcinoma were included in this prospective study. Among 22 patients with clinically negative cervical lymph nodes, 4 patients (18.2%) had metastatic lymph nodes on pathologic examination. Occult node metastases were mainly located in ipsilateral II level. No occult metastases occurred at levels I and V. Among 36 patients with clinically positive cervical lymph nodes, 3 patients (8.3%) had an occult pathologic metastatic involvement of cervical lymph nodes of ipsilateral level V. Level I was free of lymph node metastases. Clinical N category >N2a (p=0.003), nodal metastases to levels III (p=0.026) and IV (p=0.009) were significantly related to level V nodal metastases. The 2 and 5 years actuarial disease-free survival was 82.7% (95% CI 71.2-93.5%) and 58.3% (95% CI 36.7-79.9%), respectively. The actuarial recurrence-free survival was 87.9% (95% CI 78.9-96.8%) and 72.2% (95% CI 53.9-90.5%) at 2 and 5 years, respectively. Our findings support the role of a selective lateral neck dissection in the management of clinically N0 necks and in selected N+ necks (N1 and N2a disease located at level II) in patients with tonsillar carcinoma without oral involvement

No full textBACKGROUND: The aim of this retrospective analysis was to analyze the results of treatment of patients with cervical node metastases from carcinoma of occult primary with a policy including neck dissection and postoperative comprehensive radiotherapy.
METHODS: Ninety patients were treated with curative intent from 1990 to 2002.
RESULTS: The actuarial rate of neck disease control was 68.8% at 5 years (95% confidence interval [CI], 58.9%-78.7%). On multivariate analysis, the rate of neck disease control was significantly related to lymph nodal metastatic level (P = .006). The actuarial rate of developing head and neck primary tumors at 5 years was 8.9% (95% CI, 2.6%-15.2%). The 5-year actuarial rate of distant metastases was 19.1% (95% CI, 9.4%-28.9%). In multivariate analysis, a statistically significant difference in the rate of distant metastasis was obtained when patients were stratified according to the level of nodal involvement (P = .01) and the presence of extracapsular extension (P = .013). At the time of analysis, 50 of the 90 patients were alive. A total of 32 (35.6%) had died from causes related to their primary disease. Actuarial disease-specific survival at 2 and 5 years was 73.6% (95% CI, 64.3%-82.9%) and 62.8% (95% CI, 51.9%-73.7%), respectively. In multivariate analysis, a statistically significant difference in disease-specific survival was obtained when patients were stratified according to the level of nodal involvement and the presence of extracapsular extension.
CONCLUSIONS: Our study seems to support the use of combined-modality therapy in patients with neck metastases from carcinoma of occult primary. However, in the absence of randomized trials, comprehensive irradiation cannot be routinely advised
