[Histologic changes in soft palate in patients with obstructive sleep apnea]. / Cambios histológicos en el paladar blando en pacientes con apnea obstructiva del sueño.

In patients suffering from obstructive sleep apnea syndrome (OSAS) the reiterate injuries against the soft structures of the pharyngeal wall causes macro- and microscopic damages, which differ basically from the alterations verified in subjects without OSAS. We present a comparative histological study of 45 patients with OSAS operated on uvulopalatopharyngoplasties to face up 10 palates coming from normal post-mortem human among which a comparative anatomopathological study of 8 parameters was realized and the differences between the two groups signaled.

[Tonsillectomy in adults. Our experience]. / Amigdalectomía en adultos. Nuestra experiencia.

[ENT emergencies due to foreign bodies at a tertiary hospital]. / Urgencias Otorrinolaringológicas por cuerpos extraños en un hospital terciario.

A study of the patients who, through a year, came to the Emergencies Department showing foreign bodies in ENT-area has been accomplished. Among ENT urgencies foreign bodies constitute the most frequent cases. Age, sex, date, time of admission, sitting, kind of body and treatment are taken in consideration. The intruders were most commonly found in the pharyngeal area. A striking correspondence between age and location is underlined.

[Inflammatory pseudotumor of the paranasal sinuses]. / Pseudotumor inflamatorio de senos paranasales.

The inflammatory pseudotumor of the head and of the neck is a lesion of unknown etiology which affects the orbita more frequently but cases have also been described in the paranasal sinuses, larynx, mouth, cervical column and by direct extension from the orbita in the Central Nervous System. In the majority of cases, it behaves as a limited benignant inflammation within the osseous walls of the area where it is to be found; other times it destroys the osseous limits and invades the surrounding areas, behaving as a neoplasia. It must be distinguished from sinusitis, granulomatous inflammations, vasculitis, diseases of the collagen, sarcoidosis, neoplasias and benignant tumours. We present a case of inflammatory pseudotumour, occupying the right maxillary sinus, nasal fossa and rhinopharynx. Surgical extirpation has been the treatment used.

[Intracranial invasion of a tumor of the ear]. / Invasión intracraneal de un tumor ótico.

A 55 years old woman with a neoplasm originating in ceruminous glands of the external auditory canal, with temporal bone and intracranial invasion, mimicking a glomus jugulare tumor. This group of neoplasms, rare in man, are best treated by and aggressive wide "en bloc" temporal bone and contiguos structures resection. In our review few similar cases are found.

[Malignant tumor of the external auditory canal]. / Tumoración maligna de conducto auditivo externo.

The neoplasms from the modified apocrine glands of the external auditory canal are usually included under the term ceruminoma without any reference to their histology, clinical course or prognosis. It seems better to classify them according to their histologic pattern in the following types: 1.--Ceruminous adenoma, 2.--Adenoid-cystic carcinoma, 3.--Adenocarcinoma, and 4.--Pleomorphic adenoma (mixed tumour). We describe a case of adenoid-cystic carcinoma originated at postero-superior wall of the external auditory canal which presented as an otitis of long duration, and was treated surgically and received post-operative radiotherapy. The patient is at present free of disease. We review the literature on this group of tumours of the EAC.
