Opis:
Objective: Congenital cholesteatomas of the petrous apex are rare lesions that develop insidiously, which delays diagnosis and requires a high index of suspicion. A case report of supralabyrinthine congenital petrous bone cholesteatoma and review of recent literature are presented. Methods: A 27-year-old woman presented with progressive facial palsy. Otomicroscopy did not reveal any abnormalities, and hearing was normal. Although there were no complaints of vertigo or instability, vestibular examinations indicated a non-compensated peripheral vestibular lesion. Radiological examinations revealed a lesion in the petrous apex and epitympanum that had features of a cholesteatoma. Results: To preserve normal hearing, the middle fossa approach was chosen for surgery. A damaged part of the facial nerve was reconstructed with cable graft. Conclusion: Advances in radiological imaging facilitate surgical planning, and improvements in the techniques of lateral skull base surgery enable safe and radical removal of petrous bone cholesteatomas with minimal morbidity.

Opis:
Schwann cell tumour is a rare benign neoplasms, which in approximately 25–45% of cases localises in the head and neck region. The half of them is found intracranially, within the cochleovestibular nerve (n. VIII) leading to deef. The slow growth and the lack of characteristic clinical signs influence clinically silent development of the tumour. Presence of the clinical signs may by connected with the pressure on the surrounding anatomical structures or the damage of the affected nerve. The treatment of the choice of the extracranial tumours is surgical resection. In presented case, the tumour development was signless. The attempt of the tumour enucleation was taken. Because of the difficulties with the tumour extracapsular enucleation, the decision of radical resection of the tumour and a part of the vagal nerve had been made. The vagal Schwann cell tumour is benign and rare neoplasm, that should be resected, despite it doesn’t influence the suspected patients survival. The main problem stands for the complications due to the nerve damaging during the surgery.

Opis:
The report aims to present a rare case of facial nerve schwannoma within the parotid gland. Schwannomas are benign, welldefined tumours arising from Schwann cells that form the myelin sheaths of peripheral, cranial or spinal nerves. 25–45% of them are located within the head and neck, mainly in the parapharyngeal space. The intraparotid localisation is rare. The aetiology of cancer is unknown. Preoperative diagnosis, both radiological and cytological, is difficult and often does not give the correct diagnosis. Radiologically, a multiform adenoma is usually suspected, and fine needle aspiration biopsy is nondiagnostic. Due to the rarity and benign nature of the tumour, there has been debate over the need for surgical treatment.

Opis:
Evaluation of acoustic vestibular evoked myogenic potentials (AC-VEMPs) is one of the tests performed to assess the function of the balance system. Evaluation of acoustic ocular vestibular evoked myogenic potentials (AC-oVEMPs) consists in the measurement of potentials evoked within oculomotor muscles, particularly the inferior oblique muscles (the most superficial muscles) with impulses being transmitted along the superior branch of the vestibular nerve from the utricular macula. Despite the fact that the measurement of oVEMPs was introduced relatively recently, it has found widespread use as a diagnostic tool in otology and neurotology. Despite the growing number of literature reports, the methodology of the test and the methods for the interpretation of its results are still subject to debate. This article is dedicated to various aspects of AC-oVEMP tests, including the methodology of the test, interpretation of its results and potential use in the diagnostics of vertigo.

Opis:
Paragangliomas are rare, most commonly non-malignant tumors of the autonomic nervous system. Their location within the head is rather an exception than a rule, similarly as their multifocal prevalence. The authors of this paper present a case of a patient with bi-focal paraganglioma. The first symptom of illness was facial nerve palsy, diagnosed for the period of about 3 years. After making the initial diagnosis of tympanic paraganglioma, the tumor was operated. During the next 7 years, there was a recurrence within the temporal bone. What is more, periodic imaging examination showed second foci within the neck, moreover asymptomatic. The authors discuss the natural development of paragangliomas in the region of head and neck and present the current knowledge about management of patients with a suspicion, diagnosis, and treatment of this disease.

Opis:
Introduction: Neoplasms of the parotid glands constitute about 6% of head and neck tumours, the most common of which are: adenoma multiforme and Warthin’s tumor. Schwannoma is benign, encapsulated tumor of the nerve cells (lemocytes, Schwann cells), most often it occurs in the trunk, head, extremely rarely observed in the parotid gland. 9% Schwannomas derives from the facial nerve sheath, constituting from 0.5–1.2% of all salivary gland tumors. The literature describes 80 cases of intraparotid Schwannoma. Malignant Schwannoma (MPNST) account for 5% to 10% of all soft tissue sarcomas. Highgrade MPNST tumors are aggressive, with a tendency to relapse and metastasis. Case report: We present a case report of a 84-year-old female patient presented to the Head and Neck Oncology Clinic of the Medical University of Lodz, due to the painful tumor of the left parotid region. The tumor appeared six months before hospitalization. During the physical examination, there was a polycyclic tumor with reduced mobility, the skin on the tumor was slightly red, lymph nodes uninvolved, facial nerve function preserved. BACC revealed tumour tissue composed of sheets and spindle-shaped cells. The patient was qualified for surgical treatment. Under the general anesthesia the superficial lobe of the parotid gland along with the tumor was removed. After the procedure, no facial nerve palsy was found. The patient did well post-operatively and was discharged home on the 8th day after surgery. Immunohistochemical staining showed the tumour cells to be diffusely and strongly immunoreactive for S-100 protein and Ki67 40–50%. Strong and diffuse staining for S-100 protein were consistent with the malignant peripheral nerve sheath tumour (MPNST). The patient was referred for radiotherapy, due to the postoperative outcome and advanced age, no adjuvant treatment was proposed. The patient has been in observation for 1 year. No relapse was found in the follow-up studies.
Wprowadzenie: Guzy ślinianki przyusznej stanowią ok. 6% nowotworów głowy i szyi. Najczęstsze z nich to: gruczolak wielopostaciowy i guz Warthina. Schwannoma jest zmianą wywodzącą się z komórek osłonki nerwów obwodowych (lemocytów, komórek Schwanna); najczęściej dotyczy tułowia i głowy, wyjątkowo rzadko obserwowany jest zaś w śliniance przyusznej. 9% Schwannoma pochodzi z osłonki nerwu twarzowego, stanowiąc od 0,5–1,2% wszystkich guzów ślinianek. W literaturze opisano 80 przypadków wewnątrzśliniakowych Schwannoma. Transformacja złośliwa dotyczy 14%. Złośliwe Schwannoma (MPNST) stanowią od 5% do 10% wszystkich mięsaków tkanek miękkich. Nowotwory MPNST o wysokim stopniu złośliwości są agresywne, z tendencją do wznowy oraz przerzutowania. Opis przypadku: Prezentujemy opis przypadku 84-letniej pacjentki, która zgłosiła się do Kliniki Nowotworów Głowy i Szyi UM w Łodzi z powodu bolesnego guza lewej okolicy przyusznej. Wspomniana zmiana pojawiła się 6 miesięcy przed hospitalizacją. W badaniu przedmiotowym stwierdzono policykliczny guz o ograniczonej ruchomości, skóra nad guzem była lekko zaczerwieniona, węzły chłonne niepowiększone, funkcja nerwu twarzowego zachowana. W BACC atypowe komórki wrzecionowate, budzące podejrzenie rozrostu złośliwego. Chora została zakwalifikowana do leczenia operacyjnego. W znieczuleniu ogólnym usunięto płat powierzchowny ślinianki przyusznej wraz z guzem i zmienioną skórą. Po zabiegu nie stwierdzono porażenia nerwu twarzowego. Przebieg pooperacyjny prawidłowy, pacjentka wypisana do domu w 8. dobie po zabiegu w stanie ogólnym i miejscowym dobrym. Wynik badania histopatologicznego materiału pooperacyjnego: dobrze odgraniczony wrzecionowaty guz z polami martwicy, profil immunohistochemiczny: S100+; Ki67 40–50%. Rozpoznanie – MPNST. Pacjentka została skierowana na konsultację radioterapeutyczną. Z uwagi na wynik pooperacyjny oraz zaawansowany wiek, nie zaproponowano leczenia adiuwantowego. Chora pozostaje w obserwacji 1 rok. W badaniach kontrolnych nie stwierdzono wznowy.

Opis:
Introduction: Cochlear Implantation has proven beneficial in patients with profound congenital hearing impairments. Performing cochlear implantation in patients with inner ear malformation has always been a matter of dispute as congenitally deaf ears may have anatomical malformations and thus meet difficulties during operation. Therefore, it is important to focus on problems and complications encountered by surgeons performing such operations. Aim: To evaluate problems and surgical difficulties encountered in patients with congenital inner ear malformation, who underwent cochlear implantation. Material and methods: A series of 21 pediatric cochlear implant (CI) patients with known inner ear malformations determined on computed tomography (CT) of the temporal bone who underwent cochlear implantation in the Department of Otolaryngology of Martyr Ghazi Al-Hariri and AL-Yarmouk Teaching Hospital, Baghdad, Iraq, from January 2018 to January 2021. The study aimed to determine intraoperative adverse effects of these anomalies regarding electrode array insertion depths, predisposition to cerebrospinal fluid (CSF) leak through the cochleostomy, and associated facial nerve anomalies that can create problems with access to scala tympani. Results: The most common inner ear anomalies were wide vestibular aqueduct (15 patients, which makes 71.4%), incomplete partitions (5 patients, 23.8%), and common cavity (1 patient, 4.8%). As concerns CSF leak, the most common was CSF ooze (11 patients, 52.4%), CSF gusher (6 patients, 28.6%), and no CSF leak (4 patients, 19%). Among facial nerve anomalies there was only one case (4.8%) of abnormal position (more superficial and not injured) and 20 cases (95.2%) in which no anomaly was detected. As concerns electrode insertion depth, full insertion was achieved in 17 patients (81%), while incomplete insertion in 4 patients (19%). Conclusion: Cochlear implant can be successfully and safely inserted in patients with selected congenital inner ear anomalies. Surgery can be challenging in certain cases of gusher and facial nerve abnormalities, but proper radiology and good surgical technique will help avoid complications.

Opis:
Obstructive sleep apnea (OSA) is characterized by recurrent periods of upper airway obstruction (hypopneas and apneas) during sleep. It leads to repeated oxyhemoglobin desaturations, nocturnal hypercapnia, and arousals. Common symptoms include loud snoring with breathing interruptions. Excessive daytime sleepiness and cognitive impairment occur. Obstructive sleep apnea is a major cause of morbidity and mortality in Western society. Its association with an increased risk of development and progression of neurocognitive, metabolic, cardiovascular and oncologic diseases and complications is well described. The significant factor in OSA pathogenesis is reduced muscle tone in the tongue and upper airway. In the recent years, devices providing neurostimulation of the hypoglossal nerve (HGNS) were developed as an alternative for noncompliant CPAP (continuous positive airway pressure) patients. Clinical trials suggest that electrical stimulation of the hypoglossal nerve is effective. This is considered to be one of the targets of neurostimulation in the treatment of obstructive sleep apnea (OSA).

Abstract: Idiopathic facial nerve palsy, known also as Bell’s palsy, is a common condition encountered in everyday otolaryngological practice, and although the prognosis is fair, in case of incomplete recovery remains a marked physical disability for the patient. Despite of the development of diagnostic techniques, in most cases it is still impossible to point the etiologic factor, and therapy has to remain on empirical treatment. Material and method: In this article the review of literature on pathogenesis and therapy of idiopathic facial nerve palsy, published in years 2006–2016 was performed, presenting the articles with direct implications for everyday clinical practice. Results: According to presented articles, the importance of usage of combined treatment with steroids and antivirals, extended diagnostics for the presence of metabolic disorders(IGT) and surgical treatment with early facial nerve decompression in cases with severe degeneration of the fibers or recurrent paralysis were emphasized

Opis:
Carcinoma of the external auditory canal (EAC) is known to be very rare with a rate of 1-6 per million people. It affects mostly people over the age of 50 regardless of gender. The most common type of carcinoma of EAC is squamous cell carcinoma (SCC). The aim of this paper is to present the case of a 56-year-old woman with carcinoma of EAC. She was admitted to otolaryngology clinic due to ear buzzing lasting for five months, periodic otorrhea and hearing deterioration in her right ear. In otoscopic examination a tumor in the right ear meatus was identified. It filled almost the entire canal. Biopsy confirmed the presence of squamous-cell cancer. Tumor advancement was diagnosed using computer tomography of the temporal bones, magnetic resonance imaging of the head and ultrasonography of the neck. Imaging examinations indicated T3 N0 stage. Doctors decided to perform lateral petrosectomy with elective neck dissection. During the operation, the results of histopathological examination of frozen specimens from marginal tissues revealed an invasion of the anterior wall of the ear canal, capsule of temporomandibular joint and parotid gland. The resection eventually included also parotid gland and temporo-mandibular joint with the caput of the mandible. After recuperation, the patient had complementary radiotherapy. The presented case shows that precise imaging is necessary before surgical treatment, but unfortunately the invasion of cancer may not be estimated properly. Based on literature, the best prognosis concerns wide resection with complementary radiotherapy, although the schedule of treatment is not determined.

Opis:
Idiopathic facial nerve palsy, also called Bell’s palsy, can be a challenge for clinicians if a pregnant woman reports symptoms of facial paresis. The incidence of Bell’s paralysis in pregnant women is almost three times higher than in the age group of non-pregnant women. The problem is lack of guidelines for treatment of idiopathic facial nerve palsy in this group of patients. Randomized studies, but without the participation of pregnant women, showed greater efficacy in the return of nerve function after early treatment with corticosteroids than with other methods. The dilemma concerning therapy is intensified by the fact that prognosis regarding the return of facial nerve function in pregnant women is significantly worse than in the remaining population, even though the weakness of the facial muscles is diagnosed in a young woman. This article presents an example of a patient consulted in our department and a review of current literature. We introduce recommendations for treatment of pregnant women with facial nerve palsy. Benefits, advised medicines, doses, necessary precautions and potential side effects of corticosteroids, being the only ones that have proven efficacy in the treatment of Bell's paralysis in pregnant women are discussed.

Opis:
Facial nerve is the main motor supply to the part of facial skeleton system responsible for expressions. The reported rate of iatrogenic injury to the facial nerve in primary mastoid surgeries was 0.6% to 3.7%. Temporal bone is one of the most complex anatomical parts of human body. A variety of facial nerve courses has been described in literature. Normally, horizontal segment of the facial nerve traverses from geniculate ganglion to second genu which is usually situated medial and inferior to lateral semicircular canal. From here it passes posteriorly and laterally along the medial wall of the middle ear. Mastoid or vertical segment extends from the second genu to stylomastoid foramen deep to tympano-mastoid suture line from where the nerve exits out of the temporal bone. During our endoscopic dissection we encountered a grossly anomalous course of facial nerve in which after turning at second genu, the nerve curves posteriorly and lies in the floor of mastoid cavity and traverse’s its whole length of mastoid and instead of moving out of foramen it travels towards sinus plate and then takes another (3rd) turn to travel anteriorly towards the tip of mastoid from where it finally exits.
Nerw twarzowy jest najważniejszym nerwem odpowiedzialnym za ruchowe zaopatrzenie mięśni mimicznych twarzy. Częstotliwość występowania jatrogennego uszkodzenia nerwu twarzowego podczas zabiegów chirurgicznych wyrostka sutkowatego wynosi od 0,6% do 3,7%. Kość skroniowa stanowi jedną z najbardziej złożonych anatomicznie części ludzkiego ciała. W literaturze opisywane są różne warianty przebiegu nerwu twarzowego. Z reguły poziomy odcinek nerwu twarzowego przebiega od zwoju kolankowego do drugiego kolanka nerwu, położonego najczęściej przyśrodkowo i ku dołowi od bocznego kanału półkolistego. Od tego miejsca nerw biegnie ku tyłowi i do boku wzdłuż przyśrodkowej ściany ucha środkowego. Część sutkowa lub pionowa nerwu twarzowego przebiega w głębi szczeliny bębenkowo-sutkowej od drugiego kolanka nerwu do otworu rylcowo-sutkowego, przez który nerw opuszcza kość skroniową. Podczas endoskopowego preparowania kości skroniowej zaobserwowano bardzo nietypowy przebieg nerwu twarzowego, który w swoim odcinku za drugim kolankiem zakrzywia się ku tyłowi, przechodzi przez całą długość wyrostka sutkowatego i zamiast przejść przez otwór rylcowo-sutkowy biegnie w kierunku ściany zatoki esowatej, a następnie wykonuje kolejny zwrot (trzeci) do przodu w kierunku szczytu wyrostka sutkowatego, gdzie w końcu opuszcza czaszkę.

Aim: To evaluate acoustically evoked cervical and ocular vestibular miogenic potentials (AC cVEMP and oVEMP) in patients with Susac’s syndrome. We did not seek for a diagnostic replacement test in those patients, but we investigated if the combined application of AC cVEMP and oVEMPs might be helpful as an additional source of information about the disease. Material and methods: To record VEMPs, the EMG standardization method was used to continuously monitor and minimize the variability of the recordings. The stimuli were presented unilaterally one ear at a time. The waveforms were analyzed for the response, latency and amplitude. Susac’s syndrome is a rare disease and two patients were analyzed in this study. Results: In patient #1 stimulation resulted in responses on both sides with latencies within normal and symmetry limits for both c- and oVEMPs; however, the responses presented small amplitudes for cVEMPs. In patient #2, only cVEMPs were present. The P1 latencies were within normal values but amplitudes were low, in addition showing asymmetry between sides, with right side amplitude being smaller. Conclusion: The information provided by the combined application of AC cVEMP and oVEMP might be useful in the diagnostics of Susac’s syndrome revealing additional information about the affected vestibular system and be of help in the treatment and rehabilitation planning.

Opis:
Objective: The aim of this study is to present a methodology of vestibular evoked myogenic potentials registered from sternocleidomastoid muscle (SCM) using skull tap stimulation (Tap-cVEMP) in a patient with cerebellopontine angle tumor (CPAT). Material and methods: A 23-year-old female with CPAT. The methodology of Tap-cVEMP is introduced. The results of VEMP is confronted with surgical information about the tumor. Results: The results of AC-cVEMP and Tap-cVEMP revealed the inferior vestibular nerve bundle to be affected by the tumor with intact superior bundle. Information obtained from VEMP was confirmed during surgery. Conclusion: Skull Tap Vestibular Evoked Myogenic Potentials (Tap-cVEMP) may be the useful method in the diagnostics of CPAT. AC-cVEMP and Tap-cVEMP may be helpful to evaluate the functional integrity of both vestibular nerve bundles providing the information about their involvement in the pathological process.
