Submandibular space infection: a potentially lethal infection.
Full text linkOBJECTIVES: 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

Full text linkThe aim of this study was to evaluate the influence of timing of tracheoesophageal puncture (TEP)with indwelling voice prosthesis insertion regarding long-term success rate and postoperative complication. We conducted a Retrospective clinical study at tertiary academic center. There were 75 patients with primary TEP (80.6%) and 18 with secondary TEP (19.3%). Long-term success rate was 81.7%, with 80.0% in primary TEP and 88.9% in secondary TEP. No significant difference in Harrison-Robillard-Schultz Rating Scale success assessment were observed between patients with primary and secondary TEP (P = .596). The use of postoperative radiotherapy did not significantly influence the success rate. The age of patients who were older or younger than 60 years significantly influence the success rate in primary TEP (P = .012). The higher rate of complications in primary TEP was not statistically significant. These findings suggest that primary and secondary TEP are equally safe and effective procedures. Primary TEP should be preferred because of avoiding a second surgical intervention and allowing early voice restoration with a considerable psychological impact
Deep neck infections: a study of 365 cases highlighting recommendations for management and treatment
No full textThe aims of this investigation were to review the clinical behavior of deep neck infections (DNIs) treated in our institution in order to identify the predisposing factors of life-threatening complications and propose valuable recommendations for management and treatment. A total of 365 adult patients with DNIs were retrospectively identified. One-hundred and thirty-nine patients (38.1%) underwent surgical drainage. Overall, 226 patients (61.9%) responded effectively to intravenous antimicrobial therapy only. There were 67 patients (18.4%) developing life-threatening complications. Diabetes mellitus (odd ratio 5.43; P < 0.001) and multiple deep neck spaces involvement (odd ratio 4.92; P < 0.001) were the strongest independent predictors of complications. The mortality rate was 0.3%. Airway obstruction and descending mediastinitis are the most troublesome complications of DNIs. In selected patients, a trial of intravenous antibiotic therapy associated with an intensive computed tomography-based wait-and-watch policy may avoid an unnecessary surgical procedure. However, about one-fourth of patients present significant comorbidities, which may negatively affect the course of the infection. In these cases and in patients with large or multiple spaces infections, a more aggressive surgical strategy is mandatory
The impact of radiotherapy and GERD on in situ lifetime of indwelling voice prostheses.
Full text linkThe aim of this study was (1) to analyze the in situ lifetime of indwelling voice prostheses (VPs) and (2) to investigate the role of some variables on device lifetime. We conducted a retrospective clinical study of patients visiting our outpatient clinic for problems related to their VP from August 1998 to March 2006. The mean in situ VP lifetime was 180.9 days (95% CI 162.6-199.2). The mean in situ VP lifetime was 163.3 and 202.9 days in patients irradiated and not irradiated, respectively (P = 0.008). The mean in situ VP lifetime was 126.5 and 215.7 days in patients with and without endoscopic evidence of erosive-ulcerative gastroesophageal reflux disease (GERD), respectively (P < 0.001). Multivariate analysis confirmed that radiotherapy and presence of GERD significantly affected the in situ VP lifetime. This study confirmed the relationship between short VP lifetime and radiation therapy. In addition, a possible association between GERD and limited device lifetime was identified
