[Laryngeal radionecrosis as a complication of radiotherapy].

The laryngeal cartilage radionecrosis is an infrequent treatment complication with radiotherapy of head and neck tumoral lesions and it can present since a few months to many years later its application. We present the different evolution of two patients with laryngeal carcinoma treated with radiotherapy who developed laryngeal radionecrosis. The differential diagnosis with the recidiva and the primitive tumoral lesion are very important, as well as the diagnosis difficulty and its treatment.

[Middle facial necrosis secondary to cocaine abuse].

The middle facial necrosis is a rare pathology that can be found related to multiple processes that can provoque it: traumatic, chemical, infections, inflammatory and tumorals. So for its diagnosis we require a wide differential diagnosis. We present a clinic case of a nose aspirated cocaine female patient who came to our department with a middle-facial necrosis not telling to us in the anamnesis the cocaine use. We were obliged to do multiple diagnostic tests searching other possible causes.

[Sarcoidosis in otorhinolaryngology].

Sarcoidosis is a disease affecting the reticulo-histiocytary system and characterized by its several manifestations, always linked to the same lesion: the epithelioid granuloma without caseous necrosis. We make a review of this disease so scarce in our consulting rooms, and consider all patients diagnosed in our Hospital during one year-term, with their manifestations in ENT-area as well in other specialties and compare our inventory with other published series.

[Long-term course of laryngeal verrucous carcinoma].

Verrucous carcinoma is an odd kind from squamous or epidermoid carcinoma, amounting between 1 and 3.5% percent of the whole number of laryngeal growths. Its predominant sitting is glottic and are characterized through the pathological anatomy and its good prognosis. We report one case treated in our Department which evolved during 14 years and we point out its good prognosis and other particularities regarding its etiology, pathologic anatomy and diagnosis.

[Cervical emphysema caused by Forestier's disease].

Diffuse idiopathic skeletal hyperostosis is a rare cause of dysphagia, preferentially affecting older men. This condition is also known as Forestier's malady, being characterized by a paravertebral ossification of 4 contiguous vertebrae at least. Seldom is the last etiology evoked for high dysphagia after other possible diagnosis exclusion. The diagnosis is confirmed by standard or contrast radiography. Introductory treatment is medical, being the surgery indicated for serious or resisting cases. One case is reported with dysphagia as primary sign of Forestier's malady, and review of possible diagnostic exams and treatments.

[Surgery of cancer of the larynx. Analysis of the results of our cases].

After 20 years of existence of this Department we decided to carry out a review of the characteristics of our series and also of the results of treatment, according to the protocol elaborated and followed in agreement with the Tumour Committee if the Hospital. 631 medical histories of patients diagnosed and operated for cancer of larynx between 1974 and 1990 were reviewed. 83 of which (13.154%) disappeared during the 5 year follow-up period. Epidemiological, clinical, location, extension and treatment fdata were considered as well as the survival results and a single descriptive statistical analysis performed. The mean age of our study was 59.02 years, showing a clear relation to exposure to tobacco (91.44% were smokers and 63.39% of more than 20 cigarettes per day). The predominant location of the growth was supraglottic (64.05% of cases) followed by glottic in 33.76%. The most frequently used surgical technique was the total laryngectomy and total and extended to either the pharynx or tongue basis in 76.28%, followed by supraglottic laryngectomy in 13m5%. The stages were rather advanced with predominance of stage III /40.60%) and stage IV (21.17%). Global survive rate of our series accounted for 68.61% while the adjusted survival rate was 71.4%.

[Endocranial invasion of inverted papilloma].

Inverted papilloma (PI) is a benign neoplasm of nose and paranasal sinuses. IP's pathophysiology is characterized by its capacity to be locally destructive, its ability to grow rapidly and its tendency to recur. IP's association with carcinoma is about 13 percent of cases. The surgical treatment of IP has evolved over the years, with a progression toward more radical en bloc extirpation. The paper reports an inverted papilloma case of nasal cavities, with destruction of frontal sinus roof and intracranial extension aside frontal lobe displacement.

[ENT changes in Crouzon's syndrome].

Crouzon's syndrome is a chapter of the craneosynostosis, congenital diseases characterized for the precocious closure of cranial sutures. It represents an autosomal dominant heredity. Recently has been find out that the mutation lies in the short arm of chromosome 10, which causes the alteration of type 2 receptor of growth factor of fibroblasts (FRFG2). Clinically together with the cranial deformities appear frequently malformations in ENT-sphere, but only in 3 percent of all cases has been observed otic changes. We present the case of a young girl of 16, bearing a Crouzon's syndrome, coming to our office because of bilateral hypacusis. Clinical examination and complementary tests showed bilateral atresia of both auditive meatus lack of mastoid pneumatization, anomalous facial route and heavy bilateral transmissive hearing impairment, together with septum nasi deflection and hypoplasy of paranasal sinuses.

[Mortality in laryngeal cancer surgery].

UNLABELLED: The causes of death were studied in a series of 171 patients who died in a 5-year follow-up period, out of a total of 631 patients who underwent different surgical techniques for cancer of the larynx. MATERIAL AND METHODS: The case histories of 631 patients who had undergone surgery between 1974 and 1990 were reviewed; 83 did not have a 5-year follow-up and were excluded from the study. A descriptive and inferential statistical study was made of the remaining cases to determine the relation between cause of death and tumoral extension, primary location, degree of tumoral differentiation, surgical technique and other data. RESULTS: Ninety-one patients died from local or regional recurrence, 50 from distant metastases, 20 from diseases other than the tumor, and 10 from postoperative complications. These findings were studied with regard to factors such as tumor extension, location, surgical technique, etc. CONCLUSIONS: The main cause of death in surgery for cancer of the larynx was recurrence, either local, on the tumor bed (62 patients) or regional (29 patients). The mortality rate was higher in older patients, patients with lymph-node involvement in the postoperative histological study, and patients with less differentiated histological forms.

[Vernet's syndrome as an early manifestation of systemic erythematous lupus].

Report of one case of Vernet's syndrome (involving the IX, X and XIth cranial nerves) in a young woman, as early sing of SEL. The patient presented the 4 criteria suggested by the American Society in order to diagnose SEL: arthritis, serositis, positive anti-nuclear antibodies and anemia. The AA. carry out a study in search of other cases sitting in the larynx and a perusal about etiopathogenical theories as well. Hinting, for the clinical picture, of being it due to a localised vasculitis of vasa nervorum, a treatment with corticoids and pentoxifylline was ordered, being the outcome, after 3 weeks, the eradication of ENT syndrome.

[Primary mucous melanoma of the nasal cavity: a case report].

Mucous melanoma in the nasal cavity are unusual tumours that develop from common melanocytes pre-existent in the respiratory epithelium. They manifest a high diagnostic and therapeutic difficulties as well as an obscure prognosis. A case of this rare tumour is exposed and a bibliographic review in which clinical, diagnostic, histological, therapeutic and prognostic features are contemplated.

[The influence of age and previous thresholds on stapedectomy results].

This is a retrospective study dealing with 719 primary stapedectomies and 48 reoperations done between 1975 and 1993 by the AA. of the paper. They consider the audiometric tracings before and after surgery (6 and 12 months). Frequencies analyzed were 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz; the air-bone gap; and modifications of bone thresholds. The patients were ranged in groups according the ages and previous bone thresholds. Thereafter an analysis aiming to a comparison of surgery results en each group was contemplated. The age resulted without influence on the postoperative gap neither in modifications of bone conduction. The previous bone thresholds nor influencing the final gap. Conversely there are significative differences (P > 0.01) regarding the modifications of bone conduction.

[Study of 288 stapedectomies performed between 1986 and 1991].

A review of 288 stapedectomies performed between 1986 and 1991 was carried out. Pre- and post-surgical (within six to nine months) audiometries were studied, analyzing the 250 Hz, 500 Hz, 1,000 Hz, 2,000 Hz and 4,000 Hz frequencies. No significant differences between age and sex, type of prosthesis or final auditive gain were found. Patients were distributed in six groups according to their initial audiometry, achieving higher auditive gain those with and worse initial audition.

[Results of 769 stapedectomies performed between 1975 and 1993].

A retrospective review was made of 719 primary stapedectomies and 48 re-operations carried out between 1975 and 1993. Preoperative and postoperative audiograms (6-12 months) were studied, analyzing 250, 500, 1000, 2000 and 4000 Hz, auditory gain and closure of the air-bone gap < or = 10 dB. Ninety percent had an auditory gain of > or = 10 dB at conversational frequencies. Age, the surgeon, and average preoperative pure tone did not influence the final result. Polyethylene prostheses (70.9%) and steel and teflon pistons (21.1%) were the prostheses used most often. Neurosensorial hearing loss (> 10 dB) occurred in 24 cases (3.3%). In revision stapedectomy, 66.6% of patients had air-bone gap closure of < or = 20 dB and 71% had a hearing gain of < or = 10 dB. Prosthesis displacement (43.7%) and incus necrosis (18.7%) were the most common findings in revision stapedectomy.
