The use of forced ventilation during microlaryngoscopy with laser CO2.

CO2 laser is currently used in the treatment of laryngeal lesions. The technique leads to vaporisation of the tissues on which it is focused, resulting in the production of smoke that remains in the laryngoscope and in the area of the exposed larynx. The fumes can only be partially removed with an aspiration tube.

Modification of lymphocyte subsets in patients with rhinoscleroma.

Purpose: Rhinoscleroma is a rare, chronic, granulomatous disorder of the upper airways. This disease presents some etiopathogenetic aspects that are not yet clear. Infection by Klebsiella rhinoscleromatis is fundamental for the onset of the disease, but it is impossible to reproduce rhinoscleroma experimentally only via infection with the bacteria both in man and in animals.

Clean-contaminated neck surgery: risk of infection by intrinsic and extrinsic factors.

Objective: To evaluate the risk of surgical wound infection (the most common complication in neoplastic clean-contaminated neck surgery) due to 10 intrinsic risk factors and 5 extrinsic risk factors.

Design: Retrospective clinical study.

Setting: Academic tertiary referral medical center.

Malignant myoepithelioma of the rhinopharynx: case report.

Malignant myoepitheliomas are rare tumors of salivary glands. Most occur in the parotid gland; few other sites of origin are described. Malignant myoepithelioma of the rhinopharynx has only been reported twice.

Mastoid osteoma.

Osteoma in the mastoid is a rare benign osteogenic tumour which has been described in literature in only 130 cases between 1861 and 2004. It is a clinically asymptomatic lesion that usually appears as a tumefaction or retroauricular protruding mass. The Authors report 2 cases of mastoid osteoma, objectively review the literature on this pathology and present theories on its etiopathogenesis, histology, symptomatology and treatment.

Mucoepidermoid carcinoma of the external auditory canal: case report.

This study reports a case of mucoepidermoid carcinoma (MEC) of the external auditory canal, which to date has only been described once in literature. Because the lesion is extremely rare, it is particularly difficult to classify it into stages following normal diagnostic parameters. This obviously limits the possibilities of treatment that consequently are either empirical or based on those of squamous cell carcinoma.
