Petrous bone cholesteatoma (PBC): report of 94 cases of PBC with focus on intraoperative endoscopic assistance, and systematic review of the literature.

Purpose: The aim of this study is to assess the clinical characteristics, classification, surgical approaches, interventional strategies, and treatment outcomes of patients with petrous bone cholesteatoma (PBC).

Methods: Observational retrospective study of patients with PBC managed by the senior author of this paper between 1995 and 2024 in a tertiary referral center. A literature review was made, identifying 16 articles.

The importance of simultaneous oculoplastic surgery in quality of life related to vision in surgical resection of large vestibular schwannomas.

Objectives: Facial nerve palsy is one of the most important complications of vestibular schwannoma resection. When VII cranial nerve is damaged, ocular complications might appear, impacting patient´s quality of life. Therefore, standardized eye care must be a priority.

Otosyphilis: Two case reports and review of the English and Spanish literature of the last 24 years.

Syphilis has significantly increased its incidence in Europe and North America in the past 20 years. Although rare, sudden hearing loss might be a complication of syphilis infection. We present two cases of otosyphilis seen in our hospitals and review of the English and Spanish literature already published since 2000.

Anatomical Variations of the Intrapetrous Portion of the Facial Nerve.

The intrapetrous facial nerve has the second longest intraosseous course of all cranial nerves, after the mandibular nerve. But it is by far the most complex considering the anatomical structures closely related to it. The auditory and vestibular portions of the inner ear, the dura of the middle fossa and posterior fossa, the sigmoid sinus and jugular bulb, and the internal carotid artery are close enough to merit attention.

The Human Laryngeal Innervation Revisited-The Role of the Neural Connections.

In spite that vascular inconvenients or immunological rejections have been solved in relation with larynx transplant, a successful functional reinnervation has not been achieved. Some studies have suggested that laryngeal nerve connection may contain motor fibers, which could explain unexpected evoked responses in electromyographic studies or the different positions adopted of the vocal folds after similar nerve lesions. Ten patients with unexpected evoked responses after laryngeal nerve stimulation were selected.

Peritonsillar and deep neck infections: a review of 330 cases.

Introduction: Deep neck infections are defined as suppurative infectious processes of deep visceral spaces of the neck.

Objective: The aim of this study is to review different factors that may influence peritonsillar and deep neck infections and may play a role as bad prognosis predictors.

Methods: We present a retrospective study of 330 patients with deep neck infections and peritonsillar infections who were admitted between January 2005 and December 2015 in a tertiary referral hospital.

Practical management of periprosthetic leakage in patients rehabilitated with a Provox® 2 voice prosthesis after total laryngectomy.

Introduction And Objectives: Periprosthetic leakage of liquids is a common complication in patients rehabilitated with voice prostheses. Our objective was to describe and review the results of procedures for treating periprosthetic leakage.

Materials And Methods: This was a retrospective analysis of 41 patients rehabilitated with Provox® 2 voice prostheses between 1997 and 2015.

Surgical treatment of vestibular schwannoma. Review of 420 cases.

Introduction And Objectives: Vestibular schwannoma is the most frequent cerebellopontine angle tumor. The aim of our study is to reflect our experience in the surgical treatment of this tumor

Material And Methods: Retrospective study of 420 vestibular schwannomas operated in our hospital between 1994-2014. We include tumor size, preoperative hearing, surgical approaches, definitive facial and hearing functional results, and complications due to surgery.

Management of vagal paragangliomas: review of 17 patients.

Vagal paragangliomas are very rare benign vascular tumors of neuroendocrine nature, and are much less frequent than carotid and jugulo-tympanic tumors. The goal of this retrospective study is to review the clinical and genetic findings, surgical treatment, and complications of vagal paragangliomas, as well as to discuss the management options. During the period 1990-2013, 17 patients with vagal paragangliomas were referred to our institution.

Conservative management of vestibular schwannoma.

Introduction: Vestibular schwannoma (VS) is a benign, slow-growing tumour originating in the 8th cranial nerve. The treatment includes microsurgery, stereotactic radiotherapy and conservative management of tumours with periodic radiological tests.

Methods: This was a retrospective study of patients with VS following conservative management in a tertiary hospital between 1993 and 2013.

Hyaluronic acid gel weight: a nonsurgical option for the management of paralytic lagophthalmos.

Objectives/hypothesis: Management of lagophthalmos should be a priority in the treatment of patients with facial palsy. The aim of the study was to evaluate the safety and efficacy of injecting hyaluronic acid gel into the upper eyelid as a nonsurgical alternative for patients with temporary facial palsy.

Method/study Design: Retrospective study of 26 patients treated with hyaluronic acid gel injected into the pretarsal region of the upper eyelid.

Cerebral salt wasting syndrome: postoperative complication in tumours of the cerebellopontine angle.

Cerebral salt wasting (CSW) is a rare complication in posterior fossa tumour surgery. We present two patients with cerebellopontine angle (CPA) tumours who developed cerebral salt wasting postoperatively. Both patients deteriorated in spite of intensive fluid and salt replacement.

Gene amplification and protein overexpression of EGFR and ERBB2 in sinonasal squamous cell carcinoma.

Background: Sinonasal squamous cell carcinomas (SNSCCs) are rare tumors with no etiologic link to tobacco or alcohol, as opposed to other squamous cell carcinomas of the head and neck. Despite improvements in the field of surgery and radiotherapy, patients with these tumors still face a very unfavorable prognosis, partly because of their localization in a complex anatomic area, which has special relevance for surgery and postoperative treatment. Therefore, there is a need for new therapeutic possibilities for patients with these tumors.

Functional role of human laryngeal nerve connections.

Objectives/hypothesis: Current knowledge of the functional role of human laryngeal nerves is based on traditional laryngeal neuroanatomic descriptions or contradictory electromyographic studies. The aim of this study was to clarify the functional role of neural connections between laryngeal nerves by correlating the different electromyographic patterns observed after laryngeal stimulation and the existence of different neural connections.

Study Design: Descriptive.
