Detection of deglutition disorders after reconstructive laryngectomy. Clinical and radiological evaluations.

Subtotal reconstructive laryngectomy is an appropriate surgical procedure for intralaryngeal squamous cell carcinoma. After this surgery the functions of the larynx are greatly modified. These functions may be retained if at least one cricoaryténoid is preserved with good function. The aim of our study was to determine the recovery of swallowing in the late postoperative period and to establish the possible causes of dysphagia. 34 patients previously submitted to reconstructive laryngectomy were studied by clinical and endoscopical evaluation as well as videofluoroscopic examination. The results of our study confirm what has been reported by other authors, that is that the sphincter function greatly altered in the early postoperative period, is progressively restored, especially when both arytenoids are preserved. Videofluoroscopic examination frequently showed the asymptomatic false passage of liquid boluses.

Clindamycin/cefonicid in head and neck oncologic surgery: one-day prophylaxis is as effective as a three-day schedule.

The aim of our study was to evaluate the optimal duration of antibiotic prophylaxis in major oncologic surgery of the head and neck using a novel broad spectrum drug combination: clindamycin and cefonicid. A prospective randomized study was carried out on 126 evaluable patients undergoing clean-contaminated (skin to mucosa) surgery for cancer of larynx, pharynx or oral cavity. Cases at high surgical risk (because of need of pedicled or microvascular free flaps reconstruction), were excluded from the study. Within 20 days after surgery, only one case of wound infection was recorded among the 62 patients treated with the one-day schedule, versus three cases registered among the 64 subjects receiving three-day chemoprophylaxis. Episodes of systemic infections and eventual wound complications occurring in the first 20 days after surgery have also been recorded. The role of potential risk factors for postoperative complications has been evaluated. According to our findings, a three-day antibiotic regimen is not more effective than a short-term (one-day) schedule in preventing wound or systemic infection in clean-contaminated head and neck cancer surgery without flap reconstruction.

A case of Merkel-cell carcinoma metastatic to the tonsil.

Metastatic tumours are rare in the tonsil. We describe a 69-year-old male patient who had previously undergone a resection of a Merkel-cell tumour of the left forearm and subsequently presented with a left tonsillar tumour. Biopsy revealed a metastatic Merkel-cell carcinoma. Our patient is the first described case of Merkel-cell carcinoma metastasizing to the tonsil. The clinical and histopathological picture of this rare tumour is presented, along with a review of literature.

Laryngeal metastasis from colonic adenocarcinoma.

Metastases to the larynx from distant primaries are very rare. Usually the secondary lesion comes from an hypernephroma or malignant melanoma. A case of metastatic laryngeal tumour from a colonic adenocarcinoma, occurring in a 59-year-old woman, is presented and the routes for laryngeal spread are discussed. The poor survival-rate of these patients justified only conservative surgery.

Short-term versus long-term antimicrobial prophylaxis in oncologic head and neck surgery.

BACKGROUND: Although antimicrobial prophylaxis is mandatory in major clean-contaminated oncologic surgery of the head and neck, both the choice of specific antimicrobial compounds and the treatment duration are still discussed. METHODS: A prospective, randomized trial was carried out to compare efficacy and tolerability of clindamycin-cefonicid administered for 1 day versus 3 days in reducing the rate of wound and systemic infections. The following potential risk factors for surgical wound infection were evaluated: type of surgery, stage of disease, preoperative tracheostomy, preoperative radiotherapy, and diabetes mellitus. RESULTS: One-hundred sixty-two patients were evaluable; 81 received 1-day chemoprophylaxis, while the remaining 81 were treated according to the 3-day schedule. During the first 20 days after surgery, wound infections occurred in 2 (2.5%) and 3(3.7%) patients, respectively, in the 1-day and 3-day treatment groups, so that no significant difference was found among the two evaluated chemoprophylaxis schedules. CONCLUSION: A 3-day schedule did not prove useful in preventing wound and systemic infections. All presumed risk factors were not associated with an increased rate of wound infections, although preoperative radiotherapy was associated with a greater severity of infections and a higher risk of late wound complications.

[Ultrasound staging research of progressive pathology of the base of the tongue].

Diagnosis of tongue tumours is often retarded mainly because tumours grow prevalently in deep muscular layers. A correct exploration of the region might be difficult solely employing clinical examination. Therefore, it would be useful to confirm the suspect of a neoplastic lesion at the base of the tongue with a promptly available imaging method. These considerations led us to evaluate ultrasonography (US) as a diagnostic tool for neoplastic lesions of this region. Initially 10 normal patients were studied in order to become familiar with US anatomy of the area. In a second phase our study involved 24 patients with diagnosed carcinoma of the tongue base and 26 patients with clinical suspect of neoplasm in the region. US examination was carried out with real-time equipment provided by a 5 Mhz convex transducer. Patients were examined in supine position with the neck hyperextended. Longitudinal, oblique and transverse scan of the submental region were obtained. The study showed that US gives detailed images of the floor of the mouth and the tongue. Neoplastic infiltration of the base of the tongue is clearly recognizable as a hypoechoic area. It was possible to detect masses ranging from 1.4 to 3.8 cm. In cases of larger lesions, US was useful in evaluating deep infiltration, whereas in other cases the method allowed the diagnosis of small lesions with submucosal growth. US did not proved to be highly reliable in the diagnosis of lesions confined to superficial planes (false negative results).(ABSTRACT TRUNCATED AT 250 WORDS)
