[Cytogenetic study in otosclerosis]. / Estudio citogenético en la otoesclerosis.

In 50 patients (32 females and 18 males) with otosclerosis who underwent stapedectomy, a cytogenetic study of chromosomal abnormalities was made. No description of G banding in patients with otosclerosis was found in the literature. No chromosomal abnormalities were found in the karyotype using this technique.

[Human leukocyte antigen and otosclerosis]. / Antígeno leucocitario humano y otoesclerosis.

Fifty patients (32 women, 18 men) who underwent stapedectomy [FISCH, V. (1), 1982] for otosclerosis were studied. Histo-compatibility antigens were typed in all patients using the microlymphocytic test to determine antigens of the HLA system loci A and B. Statistical comparison of results with those obtained in a control group of 339 persons without otosclerosis showed that otosclerosis has a genetic HLA-related component.

[Adenocarcinoma of the ceruminous glands: report of three cases]. / Adenocarcinoma de glándulas ceruminosas: presentación de tres casos.

We report three cases of ceruminoma seen in our department over a 1-year period and review the neoplasms of the ceruminous glands. According to the Welti classification, our three cases were ceruminous adenocarcinomas. Based on existing literature, ceruminous adenocarcinoma is the least frequent neoplasm of the ceruminous glands.

[Long-term (5 years) comparative study of patients with phonatory prosthesis: myotomy versus non-myotomy]. / Estudio comparativo a largo plazo (cinco años) de pacientes con prótesis fonatoria: miotomía versus no-miotomía.

A group of 122 patients that underwent a total laryngectomy and phonatory prosthesis surgery are evaluated after five years follow up. We compared three different techniques. 1) Herrmann technique; 2) total laryngectomy and inferior pharyngeal constrictor myotomy, and 3) classic total laryngectomy. Failures and complications are analyzed. A functional evaluation of the patients is made by means of oesophageal manometry and pharyngo-oesopyhageal isotopic transport. Voice quality is assessed in each group. As a conclusion inferior pharyngeal constrictor myotomy is very positively evaluated.

Cholesteatoma in children: results in open versus closed techniques.

Cholesteatoma in children presents characteristics that differentiate it from the adult condition. Surgery has been performed in 55 ears. The main reason for referral was otorrhoea (83 per cent), either alone (29 per cent) or with hearing loss (54 per cent). Apart from three cases with an intact eardrum, a perforation was always present mostly posterior-superior (50 per cent). Open techniques were performed in 27.3 per cent of the ears and the closed technique in 72.7 per cent. Only in 18 per cent of cases was the ossicular chain normal and mobile. The attic was occupied by cholesteatoma in 79 per cent. Recurrence took place in 37 per cent and 13 per cent of the closed and open techniques respectively. Open techniques tend to be employed in the presence of extensive disease, whereas the closed technique is reserved for those with a more localized problem.

[Congenital cholesteatoma of the middle ear]. / Colesteatoma congénito de oído medio.

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.

[Tympanic homografts using formaldehyde-treated fascia (Perkin's foot)]. / Homoinjertos timpánicos de fascia formolada (pie de Perkins).

In the paper the AA. introduce their experience and the results obtained with the use of an homograft (a cast of fascia treated with formaldehyde) in order to repair tympanic membrane perforations. They discuss the anatomical and functional results.

[Total phonatory laryngectomy (Herrmann's technic). Our clinical experience]. / Laringuectomía total fonatoria (técnica de Herrmann). Nuestra experiencia clínica.

In this paper we present a follow up of 24 patients that underwent total laryngectomy with Herrmann's technique of phonatory voice prosthesis. We discuss the complications and the facts that provoqued the removal of the prosthesis.

[Our experience in the deferred use of phonatory prosthesis in laryngectomees. Secondary technic]. / Nuestra experiencia en la utilización de prótesis fonatorias en antiguos laringuectomizados. Técnica secundaria.

In this paper we introduce our experience dealing with phonatory prosthesis in laryngectomees (secondary technique). We comment about clinical evolution, results and complications.
