Resultados de un programa de detección precoz de la hipoacusia neonatal

Introduction and objectivesNeonatal hearing loss is a public health problem that meets the requirements for submission to universal screening. Our objective was to analyse the results of the early hearing detection and intervention program implemented at our centre between January 2007 and December 2010.MethodsWe studied 26,717 newborns during the period mentioned, using transient otoacoustic emissions (TOAEs) for the screening. The diagnostic phase was carried out at the hearing loss department.ResultsIn our area, there were 27,935 births between January 2007 and December 2010. The screening was performed on 26,717 children. Of these, 24,173 had positive TOAEs, 1,040 had no TOAEs and 1,504 presented TOAEs in 1 ear with absence of TOAEs in the contralateral ear. Risk factors associated with hearing loss were found in 4,674 infants. In a second phase of the program, TOAEs were given to 5,156 children, of whom 4,626 had positive otoacoustic emissions in both ears, 323 had no TOAEs in 1 ear and 207 failed this second phase. Of all children studied, 3.8% were referred to auditory brainstem response (ABR) testing and 26 children entered the cochlear implant program. The program reached coverage of 95.64%.ConclusionsThe early hearing detection and intervention program at our hospital is suitable for our environment, reaching 95.64% of coverage. We consider the relationship between effectiveness and efficiency to be positive.     

Resultados de un protocolo de preservación de órgano en pacientes con tumores localmente avanzados de la laringe

Introduction and objectivesAdvanced laryngeal carcinoma patients, candidates for total laryngectomy, nowadays have different treatment options. One of them is induction chemotherapy, which allows modulation of the second manoeuvre according to the degree of response achieved. This study presents the results of a large series of patients treated according to this protocol.MethodsRetrospective study of 370 patients with T3-T4 carcinomas of the larynx considered as candidates for total laryngectomy. All patients were treated with the protocol mentioned above.ResultsSeven patients died as a consequence of the treatment with chemotherapy. Among 363 patients finishing chemotherapy, 154 (43 %) achieved complete response and proceeded with radiotherapy. Total laryngectomy was performed in 135 (37 %) non-responders and 74 (20 %) patients were treated with radiotherapy in spite of an incomplete response to chemotherapy. Overall actuarial survival was 73 % at five years. Survival for patients with complete response and treated with radiotherapy was 77 % and for non-responders subjected to total laryngectomy it was 76 %. Non-responders treated with radiotherapy had a 5-year survival rate of 64 %, significantly different to both other groups (p = 0.01). Larynx preservation was achieved in 42 % of the patients, rising to 72 % for complete responders to chemotherapy and to 62 % in non-responders receiving radiotherapy.ConclusionsOur larynx preservation protocol including induction chemotherapy for patients with advanced carcinomas who are candidates for total laryngectomy achieved a total survival rate of 73 % with a 42 % larynx preservation rate. The response to the induction chemotherapy was the factor contributing most to larynx preservation.     

Lista de verificación de tomografía computarizada de hueso temporal y base de cráneo lateral

Computed tomography scan of the temporal bone is a fundamental imaging modality for both the diagnosis and treatment of a wide range of pathologies affecting this complex structure. Temporal bone computed tomography scan provides a more detailed depiction of bone structures, compared with magnetic resonance imaging and, for this reason computed tomography scan is the imaging modality of choice in the planning of otological surgery.The aim of this article is to present a checklist to allow the otolaryngologist to assess systematically and in an organized manner the main anatomical landmarks, anatomical variants, as well as the most common postoperative surgical changes, which can be identified before any safe otological surgery.This revision was promoted by the Spanish Society of Otolaryngology and elaborated in a checklist template divided into the different areas of the temporal bone and the lateral skull base.     

Tratamiento de la ingestión de cuerpos extraños en una unidad de urgencias de otorrinolaringología: estudio prospectivo de 204 casos

AimsTo determine how often ingested foreign bodies are found and what parameters may predict their retrieval.MethodsDuring 1 year, we prospectively studied all patients referred to our Ear Nose and Throat Emergency Unit because of foreign body ingestion.ResultsDuring the study, 204 (median age-42 years [10 months-84 years]) patients were admitted because of ingested foreign body. The most common was fish bone (88%). Most patients were admitted <24-hour after ingestion (72%) and complained of symptoms above the cricoid cartilage (79%). A foreign body was removed by Ear Nose and Throat team in 108 (53%) patients. Twenty-three (11%) patients were referred to Gastroenterology. In 9 (39%) of these patients, a foreign body was identified by esophagogastroscopy, always from the esophagus. Predictive variables for retrieval of foreign body by Ear Nose and Throat team were ingested fish bone (P=.000; odds ratio [OR] = 17.3), short duration (<6 hours) of symptoms (P=.001; OR = 2.3) and symptoms above or at the level of cricoid cartilage (P=.000; OR = 8.9). In patients with symptoms below the cricoid cartilage the rate of retrieval of foreign body by Ear Nose and Throat team (11%) was significantly increased by Gastroenterology (41%; P=.03).ConclusionsPatients with ingestion of foreign body who ingest fish bone, present within the first 6 hours or complain of symptoms at or above cricoid cartilage deserve greater investment in terms of time and resources for retrieval of ingested foreign body by Ear Nose and Throat team.     

Análisis de la potencia de salida y del rendimiento auditivo de los dispositivos auditivos osteointegrados

Background and objectiveOsseointegrated auditory devices are hearing gadgets that use the bone conduction of sound to produce hearing improvement. The mechanisms and factors that contribute to this sound transmission have been widely studied, however, there are other aspects that remain unknown, for instance, the influence of the processor power output. The aim of this study was to know if there is any relationship between the power output created by the devices and the hearing improvement that they achieve.Materials and methodsForty-four patients were implanted with a percutaneous Baha® 5 model. Hearing thresholds in pure tone audiometry, free-field audiometry, and speech recognition (in quiet and in noise) were measured pre and postoperatively in each patient .The direct bone conduction thresholds and the power output values from the processors were also obtained.ResultsThe pure tone average threshold in free field was 39.29 dB (SD 9.15), so that the mean gain was 29.18 dB (SD 10.13) with the device. This involved an air-bone gap closure in 63.64% of patients. The pure tone average threshold in direct bone conduction was 27.6 dB (SD 10.91), which was 8.4 dB better than the pure tone average threshold via bone conduction. The mean gain in speech recognition was 39.15% (SD 23.98) at 40 dB and 36.66% (SD 26.76) at 60 dB. The mean gain in the signal-to-noise ratio was ?5.9 dB (SD 4.32). On the other hand, the mean power output values were 27.95 dB μN (SD 6.51) in G40 and 26.22 dB μN (SD 6.49) in G60. When analysing the relationship between bone conduction thresholds and G40 and G60 values, a correlation from the frequency of 1,000 Hz was observed. However, no statistically significant association between power output, functional gain or speech recognition gain was found.ConclusionsThe osseointegrated auditory devices generate hearing improvement in tonal thresholds and speech recognition, even in noise. Most patients closed the air-bone gap with the device. There is a direct relationship between the bone conduction threshold and the power output values from the processor, but only in mid and high frequencies. However, the relationship between power output and gain in speech recognition is weaker. Further investigation of contributing factors is necessary.     

Experiencia de 20 años en el tratamiento microquirúrgico de la atresia de coanas

Introduction and objectivesChoanal atresia is the most common congenital nasal anomaly. Diagnosis is confirmed by endoscopic examination and computed tomography. The definitive treatment is surgical, and different surgical techniques and approaches are used. We describe our experience in transnasal microsurgical treatment of congenital choanal atresia.MethodsWe retrospectively evaluated 49 patients with congenital choanal atresia operated in the Department of Respiratory Endoscopy over a period of 20 years. The clinical variables analysed were type of atretic plate, age at diagnosis and surgery, associated malformations, maternal history of hyperthyroidism treated with methimazole during pregnancy, mode of airway stabilisation before surgery, surgical technique, complications, and outcome.ResultsMixed bilateral choanal atresia was the most frequent (29 cases). Its incidence was higher in females (61.2%). Almost 51% of patients showed associated malformations, and 7 had a history of maternal hyperthyroidism treated with methimazole during pregnancy. The surgical procedure consisted of a transnasal microscopic approach and placement of a silicone endonasal stent for one to 12 weeks. Thirty-five patients required revision after surgery. Nine patients had complications. Suitable nasal ventilation was achieved in 46 patients (93.9%). One patient died of causes unrelated to the surgery. Two patients with permeable choanae remain with tracheotomy.ConclusionThe transnasal microsurgical repair with endonasal stent proved to be a safe and effective procedure.     

Screening auditivo en niños con factores de riesgo de hipoacusia en el área 3 de madrid

The early identification of the hearing loss is very important to begin a early rehabilitation and to get a normal development of the language. Because of reason, the newborn hearing screening started, mainly in cases with risk factors. The objective of this report is to study the incidence of hearing loss in children with risk factors in the area 3 of Madrid. We realyzed hearing screening in 138 children in a period of 3.5 years, by otoacoustic emissions in younger 1 year and auditory brain stem evoked response in older 1 year. The results show that the incidence of sensorineural hearing loss is 4.34% of cases in children with risk factors, and more specifically 2.8% of bilateral profound hearing loss, and too, we detected 6.5% of transmisive hearing loss. The age of identification of hearing loss decreased to 6 months with the hearing screening programms. These results support the need of realization of hearing scrrening programms with obligatory character, though we advocate for the universal screening to include all cases of hearing loss without risk factors     

Tratamiento quirúrgico de los tumores de glándulas salivales

Introduction and objectivesSalivary gland tumours account for 3% of head and neck tumours. The aim of this study is to analyze our series of tumours of the salivary glands requiring surgical treatment at our centre from 2004 to 2007.Material and methodsThis study is a retrospective review of 49 patients diagnosed as having tumours of the major and minor salivary glands or ectopic salivary tumours, and surgically treated at our hospital between 2004 and 2007. We reviewed their clinical characteristics, imaging findings, fine-needle cytology results, surgical charts (sub-maxillectomies, parotidectomies, palatal tumour excisions and cervicotomies), final pathology findings, and course with at least one year follow-up.ResultsForty-nine salivary tumours were treated, including 43 parotid tumours (87%), 3 sub-mandibular tumours (6%), 1 palatal tumour (2%) and 2 ectopic tumours (4%). Sixteen percent of the tumours were malignant. Fine-needle cytology sensitivity was 40%, whereas specificity was 100%. Out of 43 parotidectomies, 40 (93%) were primary parotidectomies, and 3 were revision parotidectomies. Most parotidectomies (81%) were superficial or partial and 8 (19%) were total. Parotidectomy complications are similar to those described previously in the literature: permanent facial palsy in superficial or partial parotidectomy (5%), wound dehiscence or necrosis (13%), post-operative bleeding (4%), fever or wound infection (7%), sialoceles (44%) and Frey's syndrome (2%).ConclusionsParotid tumours are the most common salivary gland tumours. Most of them are benign, but Warthin's tumour is more frequent than usual in our series. Early and late complications from parotidectomy are uncommon, although sialocele is a common transitory complication in our series.     

Cirugía de implante de estimulador de nervio hipogloso en el síndrome de apnea obstructiva del sueño: nuestra experiencia preliminar

The objective of this communication is to describe our preliminary results in upper airway stimulation surgery via hypoglossal nerve stimulation implantation for obstructive sleep apnoea. We describe 4 cases and the outcomes of the surgery were analysed using the Epworth scale, apnoea-hypopnoea index, minimal O₂ Sat, average O₂ Sat and snoring intensity. In all cases a significant reduction in Epworth scale values and apnoea-hypopnoea index were obtained (P<.05). The minimum and average oxygen saturation had better values after the surgery, however, there was no statistically significant difference. The snoring severity measured subjectively changed from «intense» to «absent» in all cases. The preliminary results obtained with the upper airway stimulation surgery via hypoglossal nerve stimulation showed objective and subjective improvement after the implant activation.     

Utilidad de los colgajos e injertos endonasales en cirugía endoscópica nasosinusal y de base de cráneo. Documento de consenso

IntroductionSkull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes.ObjectivesThe target is to create a consensus document on the use of different endonasal flaps and grafts in the skull base surgery.Material and methodsLiterature review of the most relevant free grafts and vascularized flaps from the endonasal fossa. Analysis using the Delphi method on the use of the different endonasal resources for endoscopic repair of skull base defects.ResultsWe obtained two results: 1) A selection of the most representative flaps and grafts from the endonasal fossa, describing origin, surface and indications, based on a literature review. 2) A consensus document, using Delphi methodology, with general considerations (2), recommendations (10) and limitations (6) of the different endonasal flaps and grafts.ConclusionsWe present the first consensus document in the field of extended endonasal endoscopic surgery using the Delphi method as a working tool. We highlight the usefulness of the nasoseptal flap together with other endonasal flaps and grafts for skull base reconstruction.     

Plasmocitoma solitario de cabeza y cuello. Presentación de tres casos y revisión de la literatura

Solitary plasmocytoma is a rare plasmactic cell tumor occurring in the head and neck. These constitute, less than 1% of all head and neck malignancies. On initial presentation they must be differentiated from multiple myeloma. This may prove to be difficult because a varying percentage may be associated at a later date with the development of multiple myeloma. We describe three cases of plasmocytomas, one ocuured in the larynx, in the cavity nasal and other in the skull base. The clinical characteristices, diagnosis criteria and therapeutic problems (radiation, surgery or a combination of booth) are discussed and reviewed in the literature.     

Influencia de la existencia de una dehiscencia en un canal semicircular en el espesor óseo de los canales contralaterales

ObjectivesOur objective was to determine if the existence of dehiscence in the superior or posterior semicircular canal was associated with the thinning of the bone roof in the rest of the vertical canals (superior or posterior).MethodsThe thickness of the superior and posterior semicircular canals contralateral to a dehiscence was studied using computerized tomography and compared statistically.ResultsWhen a superior semicircular canal had a dehiscence, the contralateral canal showed a significant mean decrease in its thickness of 0.5 mm (SD: 0.3 mm). This was not the case if the dehiscence was in the posterior semicircular canal, where the thickness of 2.1 mm remained unchanged (SD: 1.2 mm; P=.49).When a posterior semicircular canal showed dehiscence, no significant thinning was shown in the superior semicircular (1 mm; SD: 0.4) or in the posterior contralateral (1.3 mm; SD: 0.3) canals.ConclusionThe existence of a dehiscence in the superior semicircular canal is associated with bone thinning in the canal on the opposite side, but not with the posterior semicircular canal. In contrast, if the dehiscence is in the posterior semicircular canal, contralateral and superior canal thickness is not modified.     

Programas de detección precoz de la hipoacusia infantil en España: estado de la cuestión

Introduction and objectiveIn 2003, The Ministry of Health and Consumption, together with the Autonomous Communities (CCAA), approved a minimum and basic document concerning the establishment of Early Hearing Detection and Intervention State Programmes. Since then, the Commission for the early detection of hearing loss (CODEPEH) has made several updates and recommendations to improve these programmes.The objective of this study is to carry out a comparative analysis of how the CCAA established their Early Hearing Detection and Intervention programs and if they integrate the recommendations made by CODEPEH until 2017.Material and methodThe programmes (or related documents) of 16 CCAA available on line or paper are reviewedResultsThe 16 Early Hearing Detection and Intervention strategies analyzed are different, either in the number of test to be performed, the time in which they are performed or the techniques used. More than a third of these programmes were published before 2010 and have not been updated. Otoacoustic emissions is the chosen technique as the first screening test in nine of the 16 CCAA. Only one CCAA incorporates the salivary polymerase chain reaction test for cytomegalovirus in children with altered screening test.ConclusionAll CCAA perform Early Hearing Detection and Intervention programmes but the heterogeneity does not allow drawing reliable conclusions about the result of the screening process and it would be necessary to aim for unification with the elaboration of a national programme and an integrated general database.     

El papel actual de la cirugía parcial como estrategia de preservación funcional en el carcinoma de laringe

With the current advances and recent organ preservation protocols for intermediate or advanced stage laryngeal cancer, based on chemotherapy, the role of surgery seemed replaced except for surgical rescue of tumours not responding to these treatments, total laryngectomy being the surgical option. This type of non-surgical treatment is offered as a strategy for organ preservation, as opposed to total laryngectomy. However, we believe that there are two organ-preservation strategies, surgical and non-surgical. A wide spectrum of surgical techniques is available and such techniques lead to excellent results, both oncological and functional (speech and swallowing). The aim of this paper is to present options for organ-preserving surgery for laryngeal cancer. A review of surgical techniques available for functional preservation in cancer of the larynx at intermediate or advanced stage is presented. In addition to classic approaches such as vertical partial laryngectomy and horizontal or supraglottic laryngectomy, options for conservative laryngeal surgery have improved significantly over the past two decades. Minimally invasive surgery, transoral laser surgery, and supracricoid partial laryngectomy have become important laryngeal preservation approaches for patients with laryngeal cancer. Surgery must define its role in the multidisciplinary treatment of advanced cancers of the larynx, which at present often favours (chemo)radiotherapy protocols.     

Cirugía de rescate en las recidivas locales del carcinoma de nasofaringe

Introduction and objectives

Chemoradiotherapy is the treatment of choice for nasopharyngeal carcinoma. Local recurrences are one of the leading causes of death in these patients, and surgical salvage the treatment of choice. Our goal was to evaluate and compare the results of salvage surgery in the treatment of local recurrence of nasopharyngeal carcinomas comparing endoscopic to open approaches.

Sarcoma sinovial de fosas nasales. A propósito de un caso

Synovial sarcoma is a rare tumour found in soft tissue; it is a mesenchymal spindle cell tumour that is not related to the synovial membrane. This tumour has a low incidence, the most frequent place of occurrence being the lower extremities in young adults. Synovial sarcoma of the head and neck accounts for 3–5% of sarcomas in this anatomical region. The treatment of choice for synovial sarcoma of the head and neck is complete surgical excision of the tumour mass followed by adjuvant radiotherapy.     

Carcinoma neuroendocrino primario de la piel,carcinoma de células de Merkel. Casuística 1991-2012

Introduction and objectivesMerkel cell carcinoma was first described by Toker in 1972. It is an uncommon, primary neuroendocrine skin carcinoma which appears in the dermoepidermic area, grows fast, is very aggressive and has a poor prognosis. The aim of this work is to highlight the importance of this tumour, which develops mainly in the skin of the head and neck area, and whose prevalence has increased in recent years.Material and methodWe gathered data on 16 patients suffering cutaneous neuroendocrine carcinoma treated at our hospital between September 12, 1991 and July 13, 2012. We indicated the age and gender of patients. We described the area where the tumour was located, indicating the size in millimetres, according to the major axis of the lesion.ResultsMost of the patients studied were over 70 years old, except for one who was 55. The highest frequency of cases appeared among patients aged over 80 years. In the cases studied, when the tumour appeared in the head and neck region (10/16), its location could be nasal-lateronasal, cheek-malar, upper eyelid, frontal or mandibular. The major axis of the lesion ranged between 7 and 35 mm. Unlike with epidermoid or basocellular carcinomas, recurrence and ganglionar metastases were common. Immunohistochemical (CK20) tests are essential for a correct diagnosis. Treatment is usually surgical and occasionally followed by radiotherapy and chemotherapy.ConclusionThis carcinoma is not a very common skin tumour. It appears in old age, in the head and neck region in 50% of cases and often leads to exitus.
