Robot-assisted cochlear implantation via a modified pericanal approach.

<b><br>Aim:</b> The aim of this study was to present the case with a difficult anatomy of the middle ear, in which robot-assisted cochlear implantation via a modified pericanal approach was performed.</br> <b><br>Case report:</b> The patient, a a 63-year-old male, had passed the typical procedure of qualifying for a cochlear implant at our center. However, the preoperative CT of the temporal bones showed a very anterior position of the sigmoid sinus and a very low position of the middle fossa dura in the right ear qualified for cochlear implantation.

Robot-Assisted Electrode Insertion in Cochlear Implantation Controlled by Intraoperative Electrocochleography-A Pilot Study.

Robotics in otology has been developing in many directions for more than two decades. Current clinical trials focus on more accurate stapes surgery, minimally invasive access to the cochlea and less traumatic insertion of cochlear implant (CI) electrode arrays. In this study we evaluated the use of the RobOtol (Collin, Bagneux, France) otologic robot to insert CI electrodes into the inner ear with intraoperative ECochG analysis.

Juvenile nasopharyngeal angiofibroma-20 years of experience in endoscopic treatment.

Juvenile nasopharyngeal angiofibroma is a rare, benign tumor; however, it shows local aggression and leads to profuse nosebleeds. <br/>Aim: The aim of the study is to present 20 years of experience in endoscopic treatment of this tumor. <br/>Material and methods: The material covers 71 patients treated in the years 1985-2019 at the Department of Otolaryngology and Laryngological Oncology in Poznań.

Conductive hearing loss after surgical treatment of otosclerosis - long-term observations.

<b>Introduction:</b> For many years, surgical treatment of otosclerosis has been a widely accepted approach. Hearing improvement following stapes surgery is sometimes spectacular, and good treatment results are obtained in many centers in over 90% of patients. However, in the subsequent years after the treatment, some patients develop permanent or progressive conductive hearing loss.

Primary surgical treatment versus salvage surgery: Results of free flap reconstruction performed in 100 patients with oropharyngeal cancer.

This research sought to analyze the functional results of free flap reconstruction in two groups of patients with head and neck cancer: first group started with radiochemotherapy followed by reconstructive surgery, second group underwent initiative surgery. MATERIALS AND METHODS: In a group of 100 patients, surgery was used as the primary form of treatment in 55 (55%) patients, and the remaining 45 patients (45%) had chemoradiotherapy introduced first. Statistical analysis was performed with Statistica v.

Evaluation of surgery and surgical results of Baha Attract system implantations - single centre experience of hundred twenty five cases.

Introduction: Bone-anchored hearing aids are currently well-established solutions for treatment of hearing-impaired patients.

Objective: To evaluate the surgery of the Baha Attract system, healing process and soft tissue condition after the processor activation.

Methods: 125 patients implanted with the Baha Attract system during a 3 year period in a single ENT department were analysed.

Surgical, functional and audiological evaluation of new Baha(®) Attract system implantations.

Bone-anchored hearing aids are well-established solutions for treatment of hearing-impaired patients. However, classical systems with percutaneous abutments have disadvantages concerning aesthetics, hygiene and adverse soft tissue reactions. The study aimed to evaluate surgical, functional and audiological results of a new Baha(®) Attract system, in which the sound processor is attached by magnetic force.

[Anterior commissure status in patients with larynx cancer].

Aim Of The Work: Assessment of directions and ways of cancer spreading in the anterior commissure of the larynx, depending on the tumor location, age, sex of patients in a clinical trial and in microscopic serial section study.

Materials And Methods: The study included 50 larynx preparations obtained from open partial and total laryngectomies (F-7; M-43). For the assessment of larynx anterior commissure microscopic status 28 larynx preparations with macroscopic free anterior commissure were used.

[Cost effectiveness of a free forearm flap in reconstruction of the oral cavity and pharynx--the donor site complications].

Purpose: Evaluation of the donor site efficiency in patients after reconstructive surgery with use of free forearm flap. All patients were treated for oral cavity and larynx cancer.

Materials And Methods: a group of 21 patients (16 men and 5 women) treated in 2007-2011.

[The reasons of laryngo-tracheal stenosis: a review of literature and analysis of 124 patients].

Laryngo-tracheal stenosis (LTS) is a relatively rare disease, caused usually by iatrogenic reasons (intubation, tracheotomy, radiotherapy and surgery of the larynx and trachea) or by trauma. However they may be caused by another rare diseases effecting the wall of the larynx and trachea (primary stenosis) or by compression of pathological process near by (secondary stenosis). Among the primary stenosis except iatrogenic and posttraumatic there are also: congenital, postinfective (tuberculosis, syphilis, scleroma, diphtheria, histoplasmosis and the other), in connective tissue diseases (Wegener's granulomatosis, relapsing polychondritis), in blister diseases (pemphigoid cicarticans, epidermolysis bullosa hereditaria), in amyloidosis, in sarcoidosis and tracheobronchopathia osteochondroplastica.

[Endoscopic surgery for selected tumors of the nose and paranasal sinuses--practical sense of the four hands technique].

Endoscopic sinus surgery is a gold standard in chronic sinusitis since middle '80. More and more attention is put on endosnasal tumor removal with the endoscopic technique. Two major pathologies are present in the literature, the inverted papilloma and the angiofibroma.

[Is endoscopic neck surgery the future direction in neck treatment?].

The aim of the paper is to present the minimally invasive endoscopic video-assisted surgery for the neck on the basis of current literature. The different techniques include pure endoscopic procedures, open video-assisted approach and mini-access. The preliminary material constitute of three patients who undergone endoskopic sentinel lymph node biopsy and one with colli lipoma.

[Importance and usefulness of laryngological screening of the preschool children population in conductive hypoacusis diagnostics].

Introduction: Incidence of upper respiratory tract ailments among children between 2 and 9 years old is very common. Discreet symptoms, like low grade conductive hypoaccusis or articulation's disorders are ignore or imperceptible by parents. The survive of these disorders in the child's development stage has a direct influence on cognitive functions, speech and social development and progress in learning.

[Structure of the laryngeal anterior commissure and its role in spread of malignant neoplasms].

Since many years anterior commissure of larynx is a field of scientific research. However it is still known as a "X space", or "plane 0", because of lack of its universally accepted anatomical and clinical definition. Authors have made literature survey about development and structure of the anterior commissure of larynx.
