We have performed, with light microscope, a study about the distribution and morphology of the subepithelial glands of the hamster's larynx. The results are: at the base of the tongue the great deal of the glands are mucous, at the epiglottic base seromucous and at the subglottic space (at the level of cricoid cartilage) serous.

An histologic study was performed by light microscopy of the rat nasal cavity. A neuroepithelial lining is found in the backside of the cavity and the medial portion of vomeronasal organ. A respiratory seudostratified epithel with a great deal of submucous glandulae cover the remainder of the cavity.

We have performed an histochemical study with lectins of normal nasal mucosa in 6 patients admitted at Hospital because an abdominal pathology, and other 6 with nasal polyps. Results showed a similar reactivity to lectins of excretory duct cells of seromucous glandulae of basement membrane of normal nasal mucosa and the analogous cells of the nasal polyps mucosa.

We have performed an histochemical study with lectins of the normal nasal mucosa of 6 patients. These patients were admitted at the Hospital for abdominal surgery. A wide biopsy was taken of the inferior nasal turbinate mucosa. The results show a different reactivity between the serous and mucous cells of the submucosal glands and with the goblet cells. We have not found reactivity to DBA, SBA and LTA lectins.

We present a case of cavernous laryngeal hemangioma in an elderly lady. The limited surface of the lesion and its location and implantation basis as well allowed an endolaryngeal surgery.

We describe a typical case of eosinophilic ulcer of the oral mucosa (EUOM) after an adverse reaction to carbamazepine, in a manic-depressive patient. This case may be suggestive of other etiologic factors for the EUOM, different to traumas.

Inferior nasoantral windows, with and without radical surgical removal of the maxillary sinus mucosa, were studied in ten New Zealand white rabbits. Surgical removal of the mucosa and the Caldwell-Luc operation were performed. After three months, the sinus cavity was smaller, the medial wall was retracted and the inner curtain was disturbed, and small antrostomies had closed.

Inferior nasoantral windows, with or without radical surgical removal of the maxillary sinus mucosa, were evaluated in 15 New Zealand white rabbits. After three months, specimens were obtained for examination. Bacteriological cultures and light and electron microscopic studies were made. Mucociliary clearance was studied. Differences were found in the antrostomy patency rate between radical antrostomy and inferior nasoantral windows. After three months, the creation of a temporary inferior nasoantral window did not change the maxillary sinus mucosa and did not increase the rate of sinus infections in rabbits.

Primary laryngeal actinomycosis is rare. The case of a woman with diabetes that presented with a 2-month history of hoarseness and cough is reported. The literature is reviewed and the clinical features and histology of laryngeal actinomycosis are discussed.

The effect of inferior nasoantral windows on mucociliary clearance, with or without radical surgical removal of the maxillary sinus mucosa, was evaluated in five New Zealand white rabbits. Mucociliary clearance was analyzed using India ink as a marker and observing its distribution and flow rate. Partial and radical surgical removal of the mucosa, nasoantral windows, and the Caldwell-Luc operation were performed and mucociliary transport was studied. After three months, mucociliary clearance was conserved after partial resection of the sinus mucosa and absent after radical mucosal resection.

This paper reports a rare case of a 69-year-old man bearing a right parotid lump, measuring near 5 cm diameter, which diagnosis resulted a Warthin's tumor. The used procedure to reach the diagnosis was aspiration through a fine needle. Two months after the laboratory diagnosis--so within the preoperative term--we can corroborate the clinical and radiological missing of the growth. Review and analysis of etiologic and pathogenic mechanisms.

We described 2 cases of pleomorphic adenoma as parapharyngeal masses, one of the deep lobule of the parotid gland and the other one in palatine accessory salivary glands. After computed tomography (CAT) we made the anatomopathological diagnosis of pleomorphic adenoma with fine needle aspiration. We discuss about the role of CAT in diagnosis of pleomorphic adenoma occupying the parapharyngeal space.

A macroscopic study and with light microscopy as well is performed in the larynx of 4 hamsters. Morphology of hamster's larynx is described. Transitional epithelium is found out on the epiglottis base and caudally to the vocal cords. Hamster's larynx may be a good model for experimental study of changes during carcinogenesis.

Submucosal glands (SG) are the most important secretory elements in the human nasal mucosa. However, there is little information about the glycoconjugates of the SG secretions. Ten patients were selected in an aleatory way and a wide biopsy of the right inferior nasal turbinate mucosa was performed. The patients did not present any otorhinolaryngologic disease and the nasal exploration was normal. The serous cells of SG show a moderate reactivity to WGA, N-PNA, N-WGA and ConA and mild to WEA-I. The mucus cells of SGNM demonstrate a strong reactivity to N-PNA and N-WGA, moderate to WEA-I and WGA and there is no reactivity to Con-A. For DBA, SBA and LTA lectins no reactivity was observed.

A comparative histochemical study of the lectins was made in the normal nasal mucosa of 6 patients admitted for abdominal disease and in the nasal mucosa of 6 patients with nasal polyposis. The results showed a similar reactivity to lectins by the cells of seromucosal glands of the lamina propria in both normal nasal mucosa and the mucosa of nasal polyps.

Thirty New Zealand White rabbits underwent unilateral partial or complete removal of maxillary sinus mucosa in order to evaluate submucosal maxillary sinus glands. After three months, specimens were taken for examination from all operated on and control sinuses. Bacteriological cultures, light and electron microscopy were performed. Histopathological findings showed a decrease in the number of serous glands and significant inflammation was present in the sinus in which there was complete surgical removal. Electron microscopy revealed changes in the secretory cells of the serous glands in the regenerated post-surgical mucosa.

To evaluate partial or radical surgical removal of the maxillary sinus mucosa, 20 New-Zealand albino rabbits were used. After three months, specimens were taken for examination. Bacteriological cultures, light- and electron microscopy were performed, and mucociliary transport was studied. These experimental findings add further support to the concept of performing a conservative sinus procedure rather than a radical removal as a first procedure.
