Supracricoid partial laryngectomies after radiation failure: A multi‐institutional series

Radiation therapy (RT) is one of the gold standard treatments for early laryngeal cancer, and total laryngectomy is still the most applied surgical procedure after failure. Selected recurrences can be managed by supracricoid partial laryngectomies (SCPLs).

Treatment and outcome of advanced external auditory canal and middle ear squamous cell carcinoma.

This is a retrospective study to evaluate the outcomes and complications of combined treatment, surgery with or without adjunctive intraoperative radiotherapy, of locally advanced temporal bone squamous cell carcinoma. A series of 17 patients with locally advanced squamous cell carcinoma of the temporal bone were treated between September 2002 and February 2007. Eleven patients had primary tumors, and 6 patients had recurrences. According to the University of Pittsburgh staging system, 5 patients were stage II (T2 N0), 6 patients were stage III (5, T3 N0 and 1, T1 N1), and 6 patients were stage IV (5, T3 N2b and 1, T4 N0). All patients underwent lateral temporal bone resection and pedicle flap reconstruction. Eight patients received intraoperative and postoperative radiotherapies, 4 patients underwent postoperative radiation alone, whereas 5 patients did not receive any adjunctive treatment. Median follow-up was 29.5 months. No major complications were observed. No patients were found to have residual gross tumor. Disease-free survival was 73.3%, and overall survival was 75.6%. Radical external auditory canal and/or middle ear canal resection is of utmost importance to obtain a good surgical outcome. Postoperative radiotherapy is necessary to obtain good local control; no major adverse effects were observed in the intraoperative radiotherapy patients. The incidence of major complication is minimal after pedicle flap reconstruction.

Rhabdomyoma of the Parapharyngeal Space Presenting with Dysphagia

Rhabdomyoma is an exceedingly rare soft tissue benign tumor of skeletal muscle origin classified into cardiac and extracardiac types based on location. Extracardiac rhabdomyoma is further classified into adult, genital, and fetal type depending on the degree of differentiation. Adult rhabdomyomas are rare, but morphologically characteristic, benign mesenchymal tumors with mature skeletal muscle differentiation that in 90% of cases arise in the head and neck region, mainly in the mucosa of the oropharynx, nasopharynx, and larynx, from the branchial musculature of third and fourth branchial arches. Most patients are between 40 and 70 years old, with a mean age of 60 years with a male predominance. Usually presenting symptoms include upper airway obstruction, Eustachian tube dysfunction, and mucosal or neck mass, but rarely does it arise as pure dysphagia. This article presents a case of parapharyngeal rhabdomyoma presenting with only progressive dysphagia.

A case of cervical metastases from temporal bone carcinoid

Carcinoids are neuroendocrine tumors that typically occur in the gastrointestinal tract and lung and less frequently in the head and neck region. Whereas the metastatic potential of laryngeal carcinoid is well documented, only one case of metastasis of temporal bone carcinoid to the cervical lymph nodes has been reported. We present the case of a 55‐year‐old woman with cervical metastases almost 3 years after a primary diagnosis of temporal bone carcinoid.

Cytology and human papillomavirus testing on cytobrushing samples from patients with head and neck squamous cell carcinoma.

The increasing incidence of human papillomavirus (HPV)‐related head and neck squamous cell carcinoma (HNSCC) highlights the need for simple and effective tools to evaluate head and neck lesions and their HPV status. The main objective of the current study was to investigate the association between abnormal cytology and HPV infection, assessed on cytobrushing samples, and histologically confirmed HNSCC. Second, the authors attempted to investigate whether HPV status on cytobrushing samples reflected that of the tumoral tissue.

Minimally invasive video-assisted submandibular sialoadenectomy: a preliminary report.

Open-field sialoadenectomy is the first-choice treatment for submandibular disease. Conventional surgery is based on the transcervical approach. The present study aims to demonstrate the feasibility of a minimally invasive video-assisted sialoadenectomy and to describe a new technique to perform it. A 52-year-old man affected by chronic sialoadenitis underwent minimally invasive video-assisted sialoadenectomy under general anesthesia. The ultrasound scanning of the submandibular gland showed a 6.5-cm hypertrophic gland with dilatated intraglandular ducts and a 2-cm long intraglandular sialolith. After surgery, no static or dynamic nerve deficiencies were detected, but slight temporary deficiency of the marginalis mandibulae nerve recovered in 15 days. Cosmetic results satisfied the patient. Minimally invasive video-assisted submandibular sialoadenectomy can be a feasible and safe procedure, which could be a valid choice to conventional surgery if performed on selected cases. More experience must be collected to analyze the cost-effectiveness.

Feasibility study of reduced field of view diffusion-weighted magnetic resonance imaging in head and neck tumors

Background Reduced field of view (rFOV) imaging may be used to improve the quality of diffusion-weighted imaging (DWI) in the head and neck (HN) region. Purpose To evaluate the feasibility of rFOV-DWI in patients affected by HN tumors, through a comparison with conventional full FOV (fFOV) DWI. Material and Methods Twenty-two patients with histologically-proven malignant or benign tumors of the head and neck were included in a retrospective study. All patients underwent pre-treatment magnetic resonance imaging (MRI) studies including rFOV-DWI and fFOV-DWI. The apparent diffusion coefficient (ADC) value distributions inside tumor and muscle were derived and the mean, standard deviation (SD), and kurtosis were calculated. Image distortion was quantitatively and qualitatively evaluated, as well as the capability of lesion identification. The Wilcoxon test was used to compare all variables. Agreements between the ADC estimations were assessed by Bland–Altman plots. Results Image distortion and lesion identification scores were both higher for rFOV-DWI compared to fFOV-DWI. A reduction in ADC values with rFOV-DWI emerged for both lesion and muscle, with a mean percentage difference in ADC of 6.2% in the lesions and 24.9% in the muscle. The difference in SD of ADC was statistically significant in the lesions, indicating a higher ADC homogeneity for rFOV DWI (P = 0.005). Conclusion The application of rFOV DWI in patients affected by HN tumors is feasible and promising, based on both qualitative and quantitative analyses. This technique has potential for improving the diagnostic accuracy of fFOV-DWI for the study of specific tumoral areas.

Planned neck dissection after chemoradiotherapy in advanced oropharyngeal squamous cell cancer: the role of US, MRI and FDG-PET/TC scans to assess residual neck disease.

OBJECTIVE To investigate the ability of neck ultrasounds (US), magnetic resonance imaging (MRI) and positron emission tomography (FDG-PET/TC) in detecting residual nodal disease after chemoradiotherapy in patients with advanced oropharyngeal squamous cell carcinoma (OPSCC). METHODS From 2006 to 2009, 36 consecutive patients affected by OPSCC with bulky nodal disease (>3 cm), treated with primary concurrent chemoradiotherapy, were enrolled prospectively. Nodal response to treatment was assessed by using US, MRI and FDG-PET/CT. Planned neck dissection (ND) was performed in all the patients, and the histopathological node status was compared to the imaging findings in order to establish sensitivity, specificity, accuracy and predictive values of each technique. RESULTS Metastatic disease was assessed in 18/37 (48.6%) hemi-necks, always localized in levels II-IV. US showed greater sensitivity (77.8%) and, combined with FDG-PET/TC, produced the highest negative predictive value (93.3%). US, MRI and FDG-PET/TC scans showed the highest specificity (100%), accuracy (93.8%) and positive predictive values (100%). CONCLUSIONS In the presence of advanced OPSCC with bulky nodal disease, US combined with FDG-PET/TC could be a reliable and cost-effective strategy to identify patients with complete nodal response to chemoradiotherapy that might not require post-treatment ND but only observation. When residual disease in the neck was detected, selective ND was recommended.

Pectoralis major myocutaneous flap for hypopharyngeal reconstruction: long-term results.

Surgical treatment of hypopharyngeal cancer is indicated in advanced stages and recurrent/persistent disease after conservative regimens. As of today, no criterion standard treatment is applicable to all cases. Comparing functional results, complication rates and feasibility of different techniques proposed (free flaps, gastric pull-up, etc), and poor outcome in disease-free survival and in overall survival are more related to the tumor stage rather than the reconstruction technique. The authors discuss reconstructive surgery performed in 52 patients using a pectoralis major myocutaneous flap, according to a technique proposed by Spriano et al in 2001, after total circular partial/total hypopharyngectomy and total laryngectomy from January 1993 to 2008. Primary surgical treatment was performed in 38 patients. Surgery after radiotherapy/chemotherapy failure was performed in 8 patients. Surgery after chemotherapy was performed in 6 patients. Postoperative radiation treatment was administered in 35 patients. Two patients did not receive complementary radiotherapy: 1 patient died perioperatively and 1 had previous radiation treatment in 2002 for oropharyngeal cancer. Follow-up period ranged from a minimum of 7 months to a maximum of 15 years. Overall survival was 19.6%. To date, disease-free survival is 9 (17.3%) of 52 patients. Long-term follow-up shows that late complications are low or absent. For this reason, we consider this procedure to be time-sparing and safe, especially in this category of patients commonly affected by malnutrition and other long-term diseases.

Low-grade myofibroblastic sarcoma of the larynx.

Low-grade myofibroblastic sarcoma is an uncommon sarcoma with myofibroblastic differentiation. It occurs in a wide variety of sites and has a predilection for the head and neck region. Biologically, low-grade myofibroblastic sarcoma has a propensity for local recurrence and is associated with a low risk of metastatic spread. Histologically, it can mimic a variety of different types of benign and malignant processes and often requires immunohistochemical analysis for its accurate identification. This report describes a case and discusses the differential diagnosis of a low-grade myofibroblastic sarcoma that arose in the larynx of a 69-year-old woman with a history of metastatic skin melanoma. To the best of the authors’ knowledge this is the first description in the English literature of low-grade myofibroblastic sarcoma originating in the larynx.
