Enlarged vestibular aqueduct as a cause of postneonatal deafness.

Introduction: The enlarged vestibular aqueduct (EVA) is the most frequent malformation of the inner ear associated with sensorineural hearing loss (5-15%). It exists when the diameter in imaging tests is greater than 1.5 mm at its midpoint.

Universal neonatal hearing screening and delayed hearing loss or late-developmental hearing loss.

Objective: To determine the percentage of children with permanent bilateral postnatal hearing loss in order to study its incidence, related risk factors, diagnosis and treatment.

Methods: Retrospective study to collect data on children diagnosed with hearing loss outside the neonatal period in the Hearing Loss Unit of the Hospital Universitario Central de Asturias, from April 2014 to April 2021.

Results: 52 cases met the inclusion criteria.

[Ototoxicity in cancer survivors: experience and proposal of a surveillance protocol].

Introduction: Ototoxicity occurs in different percentages in patients after treatment with platinum-based chemotherapy or cranial radiation therapy. The aim of this study was to present experience in ototoxicity monitoring.

Material And Methods: A review was made of the registry of paediatric cancer patients referred to the Children's Hearing Loss Unit from 1999 to 2019.

Application of Wireless Contralateral Routing of Signal (CROS) Technology in Unilateral Cochlear Implant Users.

Introduction: Single cochlear implantation usually provides substantial speech intelligibility benefits but bilaterally deaf, unilaterally implanted subjects will continue to experience limitations due to the head shadow effect, like single-sided deaf individuals. In the treatment of individuals with single-sided deafness one option is contralateral routing of signal (CROS) devices, which constitute a non-surgical intervention of the second ear in unilaterally implanted individuals.

Method: Twelve experienced adult cochlear implant users with Naída Q70 processor and the CROS device used in combination participated in the study.

Evaluation of vaccination coverage in cochlear implant patients at a referral hospital in Northern Spain.

Background And Objective: The risk of bacterial meningitis increases in cochlear implant patients. Therefore, pneumococcal, influenza and Haemophilus influenzae type b vaccination is indicated in this group. The aim of this study was to determine compliance with the vaccination calendar in patients implanted in a referral hospital.

Validation of the measures of cepstral peak prominence as a measure of dysphonia severity in Spanish-speaking subjects.

Introduction And Objectives: Perceptual rating of overall voice quality and other more specific perceptual dimensions is difficult, as such judgments depend on the listener's subjectivity. Thus, finding objective, valid, and accessible clinical measures to include in comprehensive voice evaluation protocols is a priority. The purposes of this study were to 1) determine the diagnostic accuracy of a single acoustic measure, smoothed cepstral peak prominence (CPPS), to predict voice disorder status from sustained vowels and connected speech samples using the software Praat; 2) to determine the relationship between measures of CPPS and perceptual ratings of vocal quality; and 3) describe the normative values of CPPS.

Vowel production in hearing impaired children: A comparison between normal-hearing, hearing-aided and cochlear-implanted children.

Introduction And Objectives: Inadequate auditory feedback in prelingually deaf children alters the articulation of consonants and vowels. The purpose of this investigation was to compare vowel production in Spanish-speaking deaf children with cochlear implantation, and with hearing-aids with normal-hearing children by means of acoustic analysis of formant frequencies and vowel space.

Methods: A total of 56 prelingually deaf children (25 with cochlear implants and 31 wearing hearing-aids) and 47 normal-hearing children participated.

Application of the acoustic voice quality index for objective measurement of dysphonia severity.

Introduction: Over the past several decades, many acoustic parameters have been studied as sensitive to and to measure dysphonia. However, current acoustic measures might not be sensitive measures of perceived voice quality. A meta-analysis which evaluated the relationship between perceived overall voice quality and several acoustic-phonetic correlates, identified measures that do not rely on the extraction of the fundamental period, such the measures derived from the cepstrum, and that can be used in sustained vowel as well as continuous speech samples.

Auditory-steady-state response reliability in the audiological diagnosis after neonatal hearing screening.

Introduction And Objectives: Conventional audiometry is the gold standard for quantifying and describing hearing loss. Alternative methods become necessary to assess subjects who are too young to respond reliably. Auditory evoked potentials constitute the most widely used method for determining hearing thresholds objectively; however, this stimulus is not frequency specific.

Intestinal-type sinonasal adenocarcinomas. Immunohistochemical profile of 66 cases.

Introduction And Objectives: Intestinal-type sinonasal adenocarcinomas are malignant epithelial tumours. Around 8-25% of all sinonasal malignant tumours are intestinal-type adenocarcinomas, which are related to wood dust exposure. Four histological subtypes have been described: papillary, colonic, solid and mucinous.

[Peritonsillar infections: prospective study of 100 consecutive cases].

Introduction: Peritonsillar infection is the most frequent complication of acute tonsillitis. Peritonsillar infections are collections of purulent material, usually located between the tonsillar capsule and the superior constrictor of the pharynx. Peritonsillar infection can be divided into abscess and cellulitis.

Medullary thyroid carcinoma and 2q37 deletion in a patient with nevoid basal cell carcinoma syndrome: clinical description and genetic analysis.

Background: Nevoid basal cell carcinoma syndrome (NBCCS) is a rare, inheritable, multisystem disorder characterized by numerous basal cell carcinomas (BCCs), maxillary keratocyst, and musculoskeletal malformations. Occasionally, it is associated with malignancies like rhabdomyoma, melanoma, and sinonasal undifferentiated carcinoma, to name a few.

Methods: A patient presented with NBCCS with a medullary thyroid carcinoma.

Schwannoma of the larynx. An infrequent laryngeal tumour.

Schwannomas are benign tumours, rare among tumours of the larynx. They normally present as supraglottic masses (because they may arise from the internal branch of the superior laryngeal nerve), most commonly involving aryepiglottic folds or false vocal folds. Most patients present with a globus sensation, dysphagia or hoarseness.

[Analysis of microsatellite instability in laryngeal squamous cell carcinoma].

Introduction And Objectives: The literature on the involvement of microsatellite instability in head and neck squamous cell carcinoma shows great variability, probably due to differences in the testing methods. Using a consensus detection system, we aimed to reach a reliable estimate of microsatellite instability prevalence in a subset of head and neck squamous cell carcinoma cases.

Methods: The microsatellite instabilityI status of 43 patients with previously untreated primary laryngeal squamous cell carcinomas was analyzed by a multiplex polymerase chain reaction assay including 5 mononucleotide repeat markers.

Solitary fibrous tumor of the petrous bone: a successful treatment option.

The patient was a 48-year-old man complaining about right hemicranial pain and deafness of 1 year's duration. MRI showed a solid well-vascularized mass destroying the mastoid and petrous bone, and with an epidural component that pulled the right cerebellar hemisphere. The patient underwent a right modified type A infratemporal approach, which allowed complete resection of the tumor, with a low morbidity.

[Transoral laser microsurgery in advanced carcinomas of larynx and pharynx].

Introduction And Objectives: There are several types of treatment for advanced squamous cell carcinomas of the pharynx and larynx. However, both open surgery and chemoradiation protocols have failed to improve control and survival. There is a tendency toward conservative treatment without worsening oncological outcomes.

[Neck mass with infrequent origin].

We report the case of a 67-year-old male diagnosed with prostate adenocarcinoma, who referred dysphagia, dysphonia and noticed the appearance of a laterocervical mass. A CT scan revealed an osteolytic soft tissue neck lesion, which was resected. Its anatomical-pathological study was compatible with metastasis of prostate adenocarcinoma.

Baroreceptor failure after bilateral resection of carotid artery parangliomas.

Multiple head and neck parangliomas are unusual pathologies. We report a case of a 24-year-old patient operated on at our centre for bilateral carotid artery parangliomas who developed baroreceptor failure after their resection. Albeit an infrequent complication, it is important to be aware of it in order to ensure is speedy diagnosis and treatment so as to avoid major post-surgical complications.

Ludwig's angina as an extremely unusual complication for direct microlaryngoscopy.

Background: An extremely rare case that to our knowledge has not been reported before is described, in which a patient had a Ludwig's angina as a complication of direct microlaryngoscopy.

Methods: We report a Ludwig's angina after a direct microlaryngoscopy for a Reinke's edema, due to erosion on the internal face of the mandible produced by compression of the laryngoscope.

Results: The patient underwent placement of 2 drainages, intraoral and cervical, and several incisions on the floor of the mouth, with intravenous corticosteroids and antibiotics and with resolution of the illness without performing tracheostomy.

[Inverted sinonasal papillomas. Review of 61 cases].

Introduction: Inverted papillomas are benign sinonasal lesions that arise primarily from the lateral nasal wall which are characterized by their tendency to recur and propensity to be associated with malignancy. The aim of this work is to analyze our experience in the treatment of these lesions, especially through the endoscopic approach.

Material And Method: We present 61 cases of sinonasal inverted papillomas that were treated at our hospital since 1983.

Simultaneous pleomorphic adenomas of the hard palate and parapharyngeal space.

We report a very unusual presentation of simultaneous pleomorphic adenomas of 2 different locations, hard palate and parapharyngeal space. Patient age of presentation is rare because these tumors are seen in younger patients. We treated a 70-year-old woman with these 2 tumors, resecting both lesions with intraoral and cervical approaches.

Malignant triton tumor of the infratemporal fossa.

Malignant triton tumor is a very aggressive type of sarcoma that comprises rhabdomyoblasts and malignant Schwann cells. It is a different entity from malignant schwannoma, characterized by their aggressiveness and poor prognosis. Head and neck location is frequent, and early diagnosis and complete resection followed by radiation therapy is important for long-term survival.

Conservative treatment of retropharyngeal and parapharyngeal abscess in children.

Parapharyngeal and retropharyngeal infections, which can potentially cause life-threatening complications, could be treated conservatively with no need for surgical drainage. A retrospective analysis of all patients diagnosed with retropharyngeal and parapharyngeal infections was performed. Information regarding age, sex, presenting symptoms, physical examination, laboratory and imaging evaluations, management, duration of hospital stay, and complications were reviewed.

[Surgical treatment of vagal paragangliomas].

Vagal paragangliomas are much less frequent than carotid and jugulo-tympanic paragangliomas and, like these other forms, can be sporadic or familial. The familial forms usually occur as isolated tumors or within syndromic entities such as multiple endocrine neoplasia type IIA-B, Von Hippel- Lindau syndrome and neurofibromatosis type 1. The genes causing the disease are located in three loci: SDHD (11q23), SDHC (1q21) and SDHB (1p36.
