Anatomy of the eustachian tube.
The auditory tube is part of a complex anatomical functional system, which even today is not completely explained. It plays a crucial role in the understanding of the pathogenesis of chronic middle ear infections and possible therapeutic interventions-particularly in infants. This paper summarizes the current knowledge of eustachian tube gross anatomy and histology, its peritubular structures and its topographic relationship to the internal carotid artery in adults. Anatomical aspects specific to infancy ar...
Interdisciplinary teleconsultation : First practical experiences with 100 patients.
PROBLEM DEFINITION: Increasing specialization can be observed in the various medical fields and as a consequence there is little professional exchange between ear nose and throat (ENT) specialists and general practitioners. At the same time there has been significant technological development in telemedicine over the last 5 years; however, this potential is not being sufficiently exploited. The objective of this project is to implement a practicable solution for teleconsulation between ENT specialists and...
Functional and audiological results of tympanoplasty type I using pure perichondrial grafts.
BACKGROUND: There are very few studies analyzing the functional und audiological results of tympanoplasty type I using pure perichondrium. MATERIALS AND METHODS: Data of 80 randomly selected patients, who had tympanoplasty surgery between 1998 and 2008 with pure perichondrium were evaluated retrospectively. Average postoperative follow-up was 9 months. The preoperative- and postoperative status of tympanic membrane, air-bone gap (ABG) and influence of perforation size and perforation etiology on closure ra...
Transoral approach for sublingual-plunging ranula.
The case of a 7-year-old boy suffering from progressive submental/submandibular swelling is reported. Following clinical and imaging diagnostics (MRI), the suspected diagnosis of a sublingual-plunging ranula was made. Surgery was performed with transoral excision of the sublingual gland in combination with excision of the ranula. Additional submandibular gland excision should be avoided.
The development of TORS in Europe.
Transoral robotic surgery (TORS) using the da Vinci® System is being performed increasingly on an international level. Particularly in the US, TORS is a common and popular technique. It has several advantages over the alternative minimally invasive surgical technique of laser surgery: the 3D-HD lens generates a magnified, three dimensional deep-field view of the surgical site; the instrument has an exceptionally high degree of freedom and, in contrast to laser surgery, non-tangential incisions are possibl...
Surgical tumor removal is often the treatment of choice in patients with head and neck squamous cell carcinoma. Depending on the extent of tumor resection, large defects are often produced in the individual head and neck regions, necessitating reconstructive surgery to avoid further functional impairment. In principle, this decision depends on the size and location of the defect, the aesthetic importance of the region and the functional significance of the area to be replaced. Reconstructive free flap proce...
Swelling of the neck following tonsillectomy : Lateral cervical fistula.
A 16-year-old patient presented with recurrent cervical swelling to the right side of the neck on coughing and sneezing. Although present since childhood, the symptoms had progressed over the preceding year. Immediately prior to this period a bilateral tonsillectomy had been performed for recurrent tonsillitis. Magnetic resonance imaging revealed a complete lateral cervical fistula extending between the thyroid and submandibular glands on the right side of the neck. Successful surgical resection accomplishe...
Iliac crest bone graft with vascular pedicle after Caldwell-Luc procedure.
The standard Caldwell-Luc procedure includes the removal of most of the maxillary sinus mucosa and the introduction of an inferior meatal antrostomy to promote sinus drainage. Pain, chronic relapsing inflammation and loss of volume are typical sequels of this procedure. Partial maxillary resection and iliac crest bone graft harvesting is a new concept and treatment option in such cases. The case of a 64-year-old woman who had previously undergone several unilateral sinus operations is presented. Fluorescein...
Therapy of chronic obstructive eustachian tube dysfunction : Evolution of applied therapies.
This paper reviews the past and present developments in the treatment of chronic obstructive eustachian tube dysfunction. Alongside tube catheterization and bougie insertion, modern approaches such as laser eustachian tuboplasty and balloon eustachian tuboplasty (BET) are described. In BET, transnasal endoscopic insertion via the pharyngeal ostium places a balloon catheter in the cartilaginous portion of the eustachian tube. This is then dilated to a pressure of 10 bar for 2 min. Up until January 2013, 35...
BACKGROUND: The acceptance of hearing aids by users with high frequency hearing loss still represents a problem. Processing algorithms that shift high frequency signal components into an audible frequency range are proposed as a solution. We looked into the issue of whether frequency compression becomes more beneficial with increasing high frequency hearing loss or/and for users with cochlear dead regions (DR). SUBJECTS AND METHODS: A total of 20 hearing aid candidates were assessed audiometrically and cla...
Current treatment strategies for papillary thyroid microcarcinoma.
The increase in the incidence of thyroid cancer is accompanied by a mortality rate that is stable or perhaps even slightly decreasing. This phenomenon is due to the increased frequency of papillary microcarcinomas (thyroid tumors with a diameter of less than 1 cm), which is presumably attributable to the improved diagnosis enabled by high resolution ultrasound and fine needle aspiration cytology. The American and European Thyroid Associations have recently published new guidelines for the diagnosis and the...
Significance of the sinus x-ray prior to septoplasty.
INTRODUCTION: There is still disagreement concerning the significance of sinus x-ray prior to septoplasty: according to the previous guidelines for Diagnostic and Therapy of the German Society for Oto-Rhino-Laryngology and head and neck surgery in 1996, a sinus x-ray prior to septoplasty was seen as "necessary." According to the guidelines from 2010, a suitable radiology imaging is just "optional." In the present study, we analyzed the significance of a sinus x-ray to exclude a chronic sinusitis prior to se...
Dacryocystorhinostomy as part of the interdisciplinary treatment of lacrimal duct.
INTRODUCTION AND METHODS: Epiphora, which leads to blurry vision, is the leading symptom for intra- and/or postsaccal lacrimal duct stenosis. Due to the anatomy of the tear duct system, which lies between the fields of ophthalmology and otorhinolaryngology, and due to newly available techniques in interventional radiology to diagnose and treat patients with intra- and postsaccal lacrimal duct stenosis, various methods for diagnosis and treatment are available. We report the results of 107 patients who unde...
Current aspects of paediatric cholesteatomas.
Cholesteatomas can be subclassified into genuine and acquired forms. Whilst epidermoid formations are the generally accepted cause of genuine cholesteatomas, metaplasia, immigration, proliferation and retraction pocket theories have all been proposed to explain the development of acquired cholesteatomas. Clinically, paediatric cholesteatomas exhibit more extensive and aggressive growth than those arising in adulthood. Molecular biological differences in terms of angiogenesis, cytokine expression and particu...
Hypoglossal nerve paresis following a marathon.
Gelatin-thrombin matrix-mediated hemostasis : Application in tonsillectomy.
BACKGROUND: To assess the feasibility of omitting thermal coagulation following cold knife tonsillectomy, we compared the use of a local thrombin hemostat (FloSeal®, FS) to bipolar electrocautery (EK). PATIENTS AND METHODS: A total of 181 patients with chronic tonsillitis or tonsillar hypertrophy were stratified in terms of patient characteristics and randomized before undergoing tonsillectomy. The follow-up period continued until postoperative day 20. RESULTS: FS-treated patients reported lower postoper...
CT-assisted navigation for retrosigmoidal implantation of the Bonebridge.
The Bonebridge is an active bone conduction implant (BCI) that is primarily indicated in patients with conductive and combined hearing loss. However, many of these patients present with a radical cavity as a result of previous surgery. In these cases, the implant should not be introduced into the mastoid region, but rather via a retrosigmoid approach to maintain separation from the pathological alteration. To ensure the best possible acoustic transduction, the Bone Conduction-Floating Mass Transducer (BC-FM...
Treatment of chronic rhinosinusitis using balloon sinuplasty : A quality of life analysis.
BACKGROUND: Balloon sinuplasty (functional endoscopic dilation surgery, FEDS) has become established as a safe therapeutic procedure for treatment of chronic rhinosinusitis. Our goal was to assess the effect on quality of life (QoL) using validated tools and identify predictive factors. MATERIALS AND METHODS: A consecutive cohort of 14 patients was evaluated using the disease-specific QoL questionnaire Sino-Nasal Outcome Test 20 (SNOT-20). The measured postoperative changes were then correlated to the resu...
Obstructive sleep apnea syndrome in the setting of Gorlin-Goltz syndrome.
Goltz-Gorlin syndrome is a rare autosomal dominant hereditary disease associated with a high rate of spontaneous mutation. Diagnosis is based on clinically defined major and minor criteria. The disease is caused by a gene mutation locating to chromosome 9q22-31. We report on a young Goltz-Gorlin syndrome patient with obstructive sleep apnea syndrome. Due to intolerance to continuous positive airway pressure (CPAP) therapy and in order to avoid a tracheotomy, we opted for an alternative therapy comprising in...
Pediatric otology : A long-term challenge.
Test-retest variability and internal consistency of the Acoustic Voice Quality Index.
BACKGROUND: The aim of this study was to determine the test-retest variability of the Acoustic Voice Quality Index (AVQI) and to investigate the weighting of the test's two components (sustained vowel and continuous speech) with regards to the final AVQI score. PATIENTS AND METHODS: During this study, 43 test subjects with varying degrees of hoarseness were each assessed twice using the AVQI. RESULTS: No statistically significant differences were found between the end results of the two AVQI repetitions (t...
Effects of different tasks on determination of the speaking fundamental frequency.
BACKGROUND: The aims of the study were to investigate the effects of different tasks on determination of the speaking fundamental frequency (SFF) using acoustic measurements and to formulate a tentative proposal based on the results of the current and other studies on this topic. METHODS: A total of 36 normophonic German subjects were examined. Nine different tasks commonly used in science and in clinical work for determination of the SFF were used. RESULTS: The maximum deviation in F(0) across all methods...
