Abstract Introduction Ramsay Hunt syndrome (RHS) is a disease caused by the Varicella Zoster virus and characterised by skin rash, peripheral facial palsy and otologic symptoms. Objective This was an epidemiological study on the incidence and prognosis of this syndrome. Methods A retrospective study was carried out on the patients diagnosed with RHS who were seen in the emergency room between January 1995 and December 2004, and were followed up for more than 6 months. Results Of the 54 patients included in this study, 7.5% had facial palsy as their first symptom, followed by otologic signs (20.2% had both simultaneously); 72.5% presented otologic signs before facial palsy. Hearing loss was reported in 26% of the patients, but was objectively present in all of them. The level of facial palsy determined the prognosis. Conclusion In this syndrome, the prognosis of facial palsy depends on the initial symptoms and clinical findings. Otologic symptoms occur more frequently in patients having a greater degree of facial nerve affectation. Vestibular symptoms have a good prognosis. Hearing loss is much more frequent than reported; as it may go unnoticed in these patients, it should always be confirmed by complementary tests.

Estudio piloto sobre el láser diodo en la cirugía estapedial

Stapes surgery has a long history. While the results are good, there is a possibility of complications that can lead to a worsening of hearing. The objective of this study was to study hearing in patients undergoing surgery using 980 Nm Diode laser in the immediate postoperative period. In no case was the bone threshold worse in the first audiometry control at 10 days of surgery. The use of a 980 Nm Diode laser thus minimises the chance of stapes footplate fracture with risk of its drop in the labyrinth. A thick stapes can be operated on without the trauma produced by drilling it. By facilitating the surgical procedure, stapes surgery with a 980 Nm Diode laser reduces the possibility of complications.

Regarding a casuistry of 1150 patients who underwent cochlear implantation, the percentage corresponded to 1.91% alterations of that portion, of which 0.17% were dehiscences. In our experience of work conducted at our department with 164 patients suffering Bell peripheral facial paralysis studied radiologically, 16.19% presented dehiscence-type alterations in petrosal computed tomography (CT) scans. Out of these, the second portion was affected in 100% of cases and in no case was the third portion of the nerve affected. Due to their rarity, we present CT images of a patient with right, severe, peripheral facial palsy (electroneurography of 1%) who presented dehiscence of the third portion of the facial nerve up to the jugular bulb in the radiographic study (Figs. 1 and 2).

Puente óseo interaritenoideo post-intubación laringotraqueal prolongada

Posterior glottic stenosis or interarytenoid fibrous adhesion is uncommon and has sometimes been misdiagnosed as cord paralysis. Laryngoscopy and laryngeal electromyography studies are the two main diagnostic aids. We present the case of a 63-year-old man under endotracheal intubation during 10 days after a cardiac procedure who was evaluated in our department for persistent dysphonia. The laryngoscopy showed a granuloma-like lesion in the posterior glottic space. During the microlaryngoscopy procedure, the osseous consistence of the interarytenoid lesion was observed. Laser surgery excision of the lesion was performed with good results. According to our review of the literature, this corresponds to the second case reported.

Tumor de saco endolinfático como causa infrecuente de síndrome de Ménière

Rafael Luis Boemo; Ana García Arumí; María Luisa Navarrete; Jenifer M. Knäpper; Pere Huguet; Enrique Perelló

Endolymphatic sac tumours are uncommon. They have been classified as adenocarcinomas with a low degree of malignancy and no metastases have yet been documented. We report on a female patient with Von Hippel-Lindau disease and Ménières syndrome suffering from an endolymphatic sac tumour. Diagnosis and early treatment are essential to preserve hearing, so long-term monitoring is recommended when this clinical combination is encountered.
