[Epidermoid cyst of the cerebellopontine angle. Report of a case].

Epidermal cysts of the cerebello-pontine angle (CPA) are lesions arising from epidermal remainders having an expansive and slow growth sitting on the PCA space or on the temporal bone. Are diagnosed approximately in the fourth life's decade by its deficient or irritant symptoms related to VIIth and VIIIth cranial nerves. It is important the nuclear magnetic resonance exam because the specific radiologic characteristics that distinguish these cysts from other conditions of CPA as neuromata or meningiomata.

[Recurrential paralysis as the first manifestation of chordoma of the petrous apex].

We report the case of a 67-year-old woman with paralysis of the right recurrent nerve. Imaging studies showed a mass in the right petrous apex and jugular foramen. Surgery was performed using a lateral approach to the skull base. The tumor excised from the petrous apex was a chondroid chordoma. Chordomas are rare dysontogenic neoplasms that arise from notochord remnants, generally on the midline. It should be included in the differential diagnosis of tumors of the skull base.

[Retropharyngeal lipoma].

Although ordinary lipoma is the most common neoplasm of mesenchymal origin, retropharyngeal lipoma is a very rare tumour and only about 20 cases have been reported. We present a further case of this kind and discuss its most important clinical features, diagnosis and treatment. Updated theories on the lipoma's etiology and their evolutive course are reviewed.

[Solitary nasal plasmocytoma].

Report of the case of one patient diagnosed of a nasal extramedullary solitary plasmacytoma, starting as an suppurated panophtalmia. Biopsy of the mass inside the nose led to diagnosis. Comments about the difficulties of histopathological differential diagnosis, underlying the need to rule out any other systemic process (multiple myeloma). The subject was treated with inductive chemotherapy and radiotherapy, being free of the illness after 4 years follow up.

[Neck adenopathies in epidermoid carcinomas of the piriform sinus: a retrospective study and 5-year survival].

Retrospective survey done with 27 patients of epidermoid carcinoma of the piriform sinus in order to ascertain the degree of regional spread--both clinic and histologic--of the neoplasm and also set up the relation between the actual adenopathies, the rate of recurrences and the actuarial survival at 5 years post-treatment term. The checked results show the bad prognosis of such tumors irrespective of the most aggressive surgery (partial hemipharyngectomy plus total laryngectomy plus neck dissection and postoperative X-ray therapy). The actuarial survival accounts for 29.6 percent after 5 years. The AA. confirm a great lymphophile tendency with an invasion percentage amounting to 55.6 percent but with a certain clinic-histologic disagreement. Relation between the frequency of adenopathies (clinical and histological), the survival and the recurrences at 5 years is indicative to a great extent that adenopathies are a pejorative circumstance of these neoplasms.

[Chemodectomas of the temporal bone].

Report of the results of radiotherapy in 12 patients suffering from chemodectomas of the temporal bone. Complete or partial remissions under both clinical and radiological aspects are argued. Discussion on radiotherapy versus surgery of these growths.

[Congenital cholesteatoma of the middle ear].

The AA. inform about 8 patients suffering from congenital cholesteatoma of the tympanomastoidal cleft. They underline the difficulties for achieving a correct diagnosis when the eardrum remains intact and remark the need to keep in mind this process for differential diagnosis of the conductive hypoacusis in childhood. As a matter of fact the AA. emphasize the few cases of recurrences after surgery, in contrast with that of relapses in child's acquired cholesteatoma.

[Prognostic value of tubo-tympanic mucociliary clearance in surgery of chronic otitis media].

The AA. have studied a group of 52 patients affected of C.M.O. (with central perforation) which underwent reconstructive surgery of the middle ear. The time of the tubo-tympanic mucociliary clearance, tried by means of a saccharin solution, was correlated with the surgical outcome. The conclusion drawn out is the success of reconstruction when the mucociliary system works well.

[Tubal function: pressure balance function versus mucociliary clearance].

Presenting the results obtained in a group of 82 ears suffering from C.O.M. The AA. check the equilibratory function through manometry and the tubotympanic mucociliary clearance by means of a saccharine solution. The studied parameters showed frequent variations though independently. Nevertheless a certain degree of parallelism between the two is suggested.

[Otitis externa maligna. Our experience].

The AA. expose the experience gained through a group of 9 cases of malignant external otitis. They review the previous circumstances, assess the results of medical and/or surgical treatment and the evolution of the processes, emphasizing the importance of prognostic factors. Twenty-two per cent was the rate mortality.

[Epithelioma of the pyriform sinus: retrospective study and survival analysis after 5 years].

We have studied 27 clinical records of patients with piriform sinus epidermoid carcinoma diagnosed and treated in our department during a period of 6 years. All the patients underwent surgery and radiotherapy. We have analyzed the survival and recurrence rates together with other parameters that may have some influence in them. We have tried to show the factors that might be in relation with the prognosis of pyriform sinus carcinoma. The statistical analysis show a survival rate of 29.6% after 5 years follow up, being the node invasion, wither clinical or histological, the main fact to have a prognostic value.

[A tubal mucociliary transport study: scintigraphy versus saccharin. A comparative study].

We have studied two different tracers in order to evaluate tubal mucociliary transport time: albumin typed with Technetium-99 and a saccharin solution. The procedure has been done in a group with normal ears and tubes, and in another one with chronic otitis media. Tubal transport time obtained is always longer with saccharin than with albumin between 21% and 66%.

[Tubal mucociliary transport in chronic otitis media].

We introduce the results that we have obtained using the mucociliary transport time in the tube in 91 ears with central perforation by means of saccharin solution. The ears have been classified in four groups regarding the situation of the perforation and results have been compared. The fastest time was obtained in the anterior site group and the slowest in the posterior side group.

[Tubal mucociliary transport: evaluation with saccharin solution].

We have studied the tubaric mucociliar transport time using a saccharin solution in: 1. A control group with normal eustachian tubes being the transport time smaller than 20 minutes. 2. A group of 30 ears with chronic middle ear disease with a central perforation; 23% of them had a transport time within normal range, in 46% the transport time was prolonged and in 30% transport was absent.

[Infantile cholesteatoma].

We present the results obtained in a group of 52 patients (55 ears), 15 years old or younger, diagnosed with middle ear cholesteatoma. After the evaluation of their clinical records, audiometry and X ray, surgery was performed by means of canal wall up procedures in 40 ears (72%) and canal wall down procedures in 15 (27%). The cholesteatoma was eradicated in 62% of the first group and in 86% of the second one. In 17 patients there was a recurrence. In those cases of canal wall up procedures they were transformed in canal wall down, or in the canal wall down the cavity was cleaned up. Only in 2 of these 17 recurrences, there was a second recurrence. In 7 cases a tympanoplasty was performed and the audiometric GAP was reduced in 57% and only in 19% when tympanoplasty wasn't performed.
