Delayed-onset facial paralysis following cochlear implantation: a case study and comprehensive analysis.

OBJECTIVES: Cochlear implantation (CI) is a surgical intervention used to rehabilitate hearing in individuals, both pediatric and adult, with severe hearing loss. It is generally a safe procedure with rare postoperative complications. Facial nerve paralysis following cochlear implant surgery poses challenges in diagnosis and treatment. METHODS: This case report details a 48-year-old male who experienced delayed facial paralysis after cochlear implantation, an uncommon occurrence with limited documentation. RESULTS: The facial nerve palsy of the patient resolved by the third week with combined therapy. DISCUSSION: The etiology of this complication is not fully understood, with latent virus reactivation, particularly HSV and VZV, hypothesized as a probable cause. CONCLUSION: Successful management involves a combination of corticosteroids, antiviral therapy, and antibiotics, leading to a favorable outcome.

Separating the Physician and Patient: A Paradigm Shift for Routine Otolaryngology Examinations in COVID-19-Like Aerosol-Contaminated Environments.

OBJECTIVE: To evaluate the attitudes of physicians and patients toward physical examination in physically separated environments using a laryngoscopic examination model. MATERIALS AND METHODS: Six experienced laryngologists performed laryngoscopic examinations in 30 patients in a closed-chamber examination unit. The physicians and patients were asked to compare all domains with their previous standard laryngoscopic examination experience using a 10-point visual analog scale (0, poor performance; 10, good performance), including effectiveness of communication, difficulty of examination, perception of safety against airborne transmission of COVID-19, applicability of the unit for future examinations, perception of protective environment, and overall comfort. RESULTS: All laryngoscopic examinations were performed successfully. Effectiveness of communication, difficulty of examination, perception of protective environment, and overall comfort did not differ between physicians and patients (P > .05 for all comparisons). However, both physicians and patients found the examination to be difficult. While physicians evaluated the system as safe against airborne transmission of COVID-19, patients were not confident that the system was safe (8.70 ± 1.93 vs 2.87 ± 2.37, respectively, P = .001). Physicians also gave a higher score to future applicability of the unit for examinations than patients (8.90 ± 1.42 vs 7.10 ± 2.62, respectively, P = .001). CONCLUSION: Physically separating the physician and patient is a feasible method of physical examination in aerosol-contaminated environments.

Prognostic importance of harvested lymph node number, metastatic lymph node number, and lymph node ratio in surgically managed laryngeal squamous cell carcinoma / Importância prognóstica do número de linfonodos coletados, número de linfonodos metastáticos e relação de linfonodos em carcinoma espinocelular de laringe tratado cirurgicamente

Abstract Introduction Lymph node metastasis is a well-known prognostic factor for laryngeal carcinoma. However, current nodal staging systems provide limited information regarding prognosis. Additional parameters should be considered to improve prognostic capacity. Objectives To assess the prognostic values of metastatic lymph node number, ipsilateral/contralateral harvested lymph nodes, and lymph node ratio in patients undergoing surgical treatment of laryngeal squamous cell carcinoma. Methods Seventy-four patients diagnosed with laryngeal squamous cell carcinoma primarily managed surgically were included in this study. The patients' pathological and survival data were obtained from their medical records. The effects of harvested lymph nodes and lymph node ratio on disease-free survival, disease-specific survival, and overall survival were analyzed. Results Ipsilateral, contralateral, and bilateral evaluations of harvested lymph nodes showed no significant associations with prognosis. Lymph node ratio was significantly associated with overall survival when evaluated bilaterally. Metastatic lymph node number showed more suitable stratification than TNM classification. Conclusions Metastatic lymph node number and bilateral lymph node ratio parameters should be taken into consideration to improve the prognostic capacity of TNM.

Resumo Introdução A metástase linfonodal é um fator prognóstico bem conhecido para o carcinoma de laringe. Entretanto, os sistemas atuais de estadiamento nodal fornecem informações limitadas sobre o prognóstico. Parâmetros adicionais devem ser considerados para melhorar a capacidade prognóstica. Objetivos Avaliar os valores prognósticos do número de linfonodos metastáticos, linfonodos ipsilaterais /contralaterais coletados e relação de linfonodos em pacientes submetidos ao tratamento cirúrgico do carcinoma espinocelular da laringe. Método Foram incluídos neste estudo 75 pacientes com diagnóstico de carcinoma espinocelular da laringe, tratados primariamente por meio de cirurgia. Os dados histopatológicos e de sobrevida dos pacientes foram obtidos de seus prontuários médicos. Foram analisados os efeitos dos linfonodos coletados e da relação de linfonodos na sobrevida livre de doença, sobrevida doença-específica e sobrevida global. Resultados As avaliações ipsilateral, contralateral e bilateral dos linfonodos coletados não mostraram associações significativas com o prognóstico. A relação de linfonodos foi significantemente associada à sobrevida global quando avaliada bilateralmente. O número de linfonodos metastáticos mostrou estratificação mais adequada do que a classificação TNM-N. Conclusões Os parâmetros número de linfonodos metastáticos e relação de linfonodos bilateral devem ser levados em consideração para melhorar a capacidade prognóstica da classificação TNM.

Incidence and Management of Delayed Epistaxis Following Endoscopic Skull Base Surgery.

OBJECTIVE: Among other complications of endoscopic skull base surgery, delayed epistaxis has not been given much importance. This report presents postoperative delayed nosebleed cases in a large number of patients who underwent an endoscopic endonasal transsphenoidal approach to the sellar region for resection of lesions. METHODS: Three hundred and sixty three patients who were reached to the sellar region by endoscopic endonasal transsphenoidal route and operated was included in the study. Retrospective chart reviewing of these patients was performed. The correlation between the duration of nosebleeds, bleeding location, treatment methods and comorbidities of the patients were evaluated. RESULTS: Ten patients (3.6%) reported delayed epistaxis in the postoperative period and were referred to the otolaryngology department. Postoperative epistaxis occurred between days 7th and 33th (mean 16.5) days. The treatment consisted of chemical silver nitrate cauterization in two patients, return to the operating room in three patients, nasal packing in five patients. CONCLUSION: Delayed postoperative epistaxis often has no obvious etiology, and intervention requires teamworking. Well-coordinated teamworking of the neurosurgeon with other specialities such as neuroradiology and otorhinolaryngology is needed to achieve better results.

Efficacy of topical isoconazole nitrate in the treatment of otomycosis.

PURPOSE: Various agents with various antifungal properties are widely used for otomycosis eradication. However, there is still no consensus on the most effective agent. Therefore, the present study aims to investigate the efficacy of topical 1% isoconazole nitrate cream in the treatment of otomycosis. METHODS: This prospective study included 43 patients who were applied to our outpatient clinic with complaints of ear pain, itching, aural fullness, and hypoacusis, and were diagnosed with unilateral otomycosis. After aspiration and cleaning, the external ear canal was filled with 1% isoconazole nitrate cream using an iv cannula and insulin syringe. Control examinations were performed on the 5th, 10th, 15th, and 20th days. In the follow-up examinations, patients were asked about how many days after the cream administration the pain and itching completely relief and the answers were recorded. RESULTS: In the first control examination of 23 (92%) of 25 patients with pain, it was observed that the pain and otoendoscopic examination findings completely recovered. In the second control, it was found that both pain and otoendoscopic examination findings completely recovered in the remaining 2 patients (25 patients, 100%). 35 patients complained of itching and it was observed that itching and otoendoscopic examination findings completely recovered in 26 patients (75%) in the first control, 5 more patients (31 patients, 88.6%) in the second control, and 2 more patients (33 patients, 94.3%) in the third control examination. CONCLUSION: Isoconazole nitrate cream appears to be an effective and easily applicable agent for the treatment of otomycosis.

Evaluation of the Presence of Sensorineural Hearing Loss and the Relationship With Intraoperative Findings in Cholesteatoma.

We investigated whether cholesteatoma is associated with sensorineural hearing loss (SNHL) and the effects of a lateral semicircular canal (LSCC) fistula, destruction of stapes, localization of cholesteatoma, and air-bone gap (ABG) size on SNHL. The charts of 159 patients who had received surgery for unilateral cholesteatoma were examined retrospectively. In all patients, air conduction and bone conduction (BC) thresholds in both ears were measured at 500, 1000, 2000, and 4000 Hz. Differences in BC thresholds between ears with cholesteatoma and contralateral ears were calculated. Demographics, localization of cholesteatoma, presence of LSCC fistula, condition of stapes, and ABG size on the affected ear were evaluated. There were significantly greater BC thresholds in ears with cholesteatoma than in normal ears for each frequency. Comparing the average BC differences at the different cholesteatoma locations, there were significant differences between the tympanic cavity + all mastoid cell group and attic, attic + antrum, and tympanic cavity + antrum groups. The BC differences at 4000 Hz were significantly high in patients with LSCC fistula. There were no significant relationships between the condition of the stapes and BC differences at any frequencies. There were significant correlations between average ABG and BC threshold differences at all frequencies. A significant relationship was found between cholesteatoma and SNHL. Patients with advanced cholesteatoma had significantly higher levels of SNHL. The BC threshold differences increased with increases in the ABG.

Prognostic importance of harvested lymph node number, metastatic lymph node number, and lymph node ratio in surgically managed laryngeal squamous cell carcinoma.

INTRODUCTION: Lymph node metastasis is a well-known prognostic factor for laryngeal carcinoma. However, current nodal staging systems provide limited information regarding prognosis. Additional parameters should be considered to improve prognostic capacity. OBJECTIVES: To assess the prognostic values of metastatic lymph node number, ipsilateral/contralateral harvested lymph nodes, and lymph node ratio in patients undergoing surgical treatment of laryngeal squamous cell carcinoma. METHODS: Seventy-four patients diagnosed with laryngeal squamous cell carcinoma primarily managed surgically were included in this study. The patients' pathological and survival data were obtained from their medical records. The effects of harvested lymph nodes and lymph node ratio on disease-free survival, disease-specific survival, and overall survival were analyzed. RESULTS: Ipsilateral, contralateral, and bilateral evaluations of harvested lymph nodes showed no significant associations with prognosis. Lymph node ratio was significantly associated with overall survival when evaluated bilaterally. Metastatic lymph node number showed more suitable stratification than TNM classification. CONCLUSIONS: Metastatic lymph node number and bilateral lymph node ratio parameters should be taken into consideration to improve the prognostic capacity of TNM.

Accessory Nerve Anatomy in Anterior and Posterior Cervical Triangle: A Fresh Cadaveric Study.

OBJECTIVE: To understand the variations and normal course of the accessory nerve (CNXI) to help more accurate and confident neck dissection. METHODS: The course of the CNXI in the neck, its relationship to the surrounding anatomic structures and the factors affecting its course were investigated. RESULTS: A total of 100 neck dissections were performed on 50 fresh cadavers. Eleven division variations were observed at the anterior triangle. The location of CNXI at the posterior border of the sternocleidomastoid muscle (PBSCM) was investigated and the ratio between the distance from the mastoid apex (MAA) to CNXI at the PBSCM and the distance from MAA to the posterior border where the PBSCM is attached to the clavicle increased as height of the subject increased (p<0.05). CONCLUSION: It must be kept in mind that it is better to search for CNXI in taller subjects more inferiorly at the posterior border of the sternocleidomastoid muscle.

Olfactory bulb magnetic resonance imaging in SARS-CoV-2-induced anosmia in pediatric cases.

In this paper, we report three cases of pediatric patients with COVID-19 infection who presented with different symptoms and also anosmia and/or ageusia. The common feature of these 3 patients is that the smell and / or taste disorder developed without nasal symptoms such as nasal congestion, nasal obstruction or rhinorrhea. Although 40% of anosmies contains viral etiologies, COVID- 19 differs from other viral anosmies by the lack of nasal congestion and runny nose. Coronaviruses could invade the brain via the cribriform plate close to the olfactory bulb and the olfactory epithelium. We may expect some structural changes in the olfactory bulb so we evaluated our patient with cranial imaging.

Anatomical and frequencies-specific hearing results of retrograde mastoidectomy.

PURPOSE: The aim of this study was to evaluate the long-term anatomical and frequency-specific hearing results of canal wall down (CWD) and canal wall up (CWU) mastoidectomy by retrograde mastoidectomy (RM) surgical method. MATERIALS AND METHODS: Patients underwent CWU and CWD procedures with method of RM, 53 and 59 patients between January 2010 and June 2015 were evaluated retrospectively. The pre- and post-operative pure tone average air-bone gap (ABG) values of these patients were recorded in detail at 0.5, 1, 2 and 4 kHz. Pre and post-operative ABG were evaluated in detail in each group in each frequency. In addition, at least two years follow-up recurrence rates were evaluated. RESULTS: In the CWU method, post-operative ABG decreased significantly at low-frequencies compared to pre-operative ABG (p < 0.05), especially at 2 kHz (p < 0.001). But, auditory improvement was not achieved at 4 kHz. In the CWD procedure, auditory improvement was not achieved both 1 kHz and 4 kHz. CWU and CWD recurrence rates were respectively 9.4% and 10.1%. CONCLUSION: Postoperative hearing results of both surgical methods provide good auditory outcome at low-frequencies. This improvement is evident in CWU especially at 2 kHz. This may be related to the protection of the external ear canal. In both surgical methods of RM, a satisfactory anatomical success was achieved with recurrence rates of around 10%. RM is a good surgical technique alternative to classical canal wall down procedure with both auditory results and low recurrence rates.

Intratympanic steroid injection and hyperbaric oxygen therapy for the treatment of refractory sudden hearing loss / Injeção intratimpânica de corticoides e oxigenoterapia hiperbárica para o tratamento da perda auditiva súbita refratária

Abstract Introduction Controversy surrounds the use of salvage therapies to treat sudden sensorineural hearing loss (SSNHL), with no consensus on recommendations. While several studies have demonstrated the effectiveness of intratympanic administration of steroids (ITS) and hyperbaric oxygen (HBO) treatment, few have compared the efficacy of ITS and HBO therapy in patients with refractory SSNHL. Objective We evaluated the efficiency of ITS and HBO therapy in patients with refractory SSNHL. Methods Patients who did not adequately benefit from systemic treatment were evaluated retrospectively. Refractory patients were defined as those who gained less than 20 dB in hearing after initial treatment. All refractory patients were informed about salvage therapy options: ITS or HBO therapy, the advantages and disadvantages of which were explained briefly. ITS involved 4 mg/mL dexamethasone administered through a 25 gauge needle. Patients underwent HBO therapy in a hyperbaric chamber where they breathed 100% oxygen for 120 min at 2.5 atmospheric pressure. The hearing levels of both groups were evaluated before the salvage therapy and at 3 months after treatment. Improvements in hearing were evaluated according to the Furahashi criteria. We also compared the two therapies in terms of speech discrimination scores (SDSs) and the recovery of all frequencies. Results The salvage therapies generated similar results. Changes in pure tone averages and SDSs were similar for ITS and HBO therapy (p = 0.364 and p = 0.113). Comparison of SDSs and hearing thresholds at all frequencies showed similar levels of improvement. Conclusion ITS and HBO therapy produced similar improvements in SSNHL patients, but the sample size was too small to draw definitive conclusions. Further randomized controlled studies are needed to identify the best therapy for patients with refractory sudden hearing loss.

Resumo Introdução Há muita controvérsia sobre o uso de terapias de resgate para tratar a perda auditiva neurossensorial súbita (PANSS), sem consenso sobre as recomendações. Embora vários estudos tenham demonstrado a eficácia do uso de corticoides intratimpânicos (CIT) e o tratamento com oxigenoterapia hiperbárica (HBO), poucos têm comparado a eficácia da terapia ITS e HBO em pacientes com PANSS refratária. Objetivo Avaliamos a eficiência da terapia com CIT e HBO em pacientes com PANSS refratária. Método Pacientes que não se beneficiaram adequadamente do tratamento sistêmico foram avaliados retrospectivamente. Pacientes refratários foram definidos como aqueles que ganharam menos de 20 dB na audição após o tratamento inicial. Todos os pacientes refratários foram informados sobre as opções de terapia de resgate: terapia com CIT ou HBO, cujas vantagens e desvantagens foram explicadas brevemente. O CIT envolveu 4 mg/mL de dexametasona administrada através de uma agulha de calibre 25. Os pacientes foram submetidos à terapia HBO em uma câmara hiperbárica onde respiraram 100% de oxigênio por 120 min a 2,5 pressão atmosférica. Os níveis de audição de ambos os grupos foram avaliados antes da terapia de resgate e três meses após o tratamento. As melhorias na audição foram avaliadas de acordo com os critérios de Furahashi. Também comparamos as duas terapias em termos de Escores de Discriminação de Fala (EDF) e a recuperação de todas as frequências. Resultados As terapias de resgate demonstraram resultados semelhantes. As alterações nas médias de tons puros e nas EDF foram semelhantes para a terapia com CIT e HBO (p = 0,364 e p = 0,113). A comparação dos EDF e dos limiares de audição em todas as frequências mostrou níveis de melhoria semelhantes. Conclusão CIT e HBO produziram melhorias semelhantes nos pacientes com PANSS, mas o tamanho da amostra era muito pequeno para tirarmos conclusões definitivas. Estudos randomizados e controlados adicionais são necessários para identificar a melhor terapia para pacientes com perda auditiva repentina refratária.

Is Pool Water Disinfectant (Hydrogen Peroxide-Silver Composition) Ototoxic in Rats?

OBJECTIVES: The purpose of our study was to evaluate whether hydrogen peroxide and silver composition (H202-Ag) used in pool water disinfectant is ototoxic to individuals with tympanic membrane perforation. MATERIALS AND METHODS: The tympanic membranes of both ears of 14 Wistar-type albino female rats were perforated. Since topical application was performed, the right and left ears were categorized as two subgroups (a: right ear, b: left ear). Baseline auditory brainstem response (ABR) was measured. The groups were classified according to topical applications performed as Ia (30 mg/L H202-Ag), Ib (saline), IIa (70 mg/L H202-Ag), and IIb (saline). The topical applications were performed for 30 min/day for 10 days. The ABR was measured 24 hours after the last application, and the animals were sacrificed. Bilateral temporal bones were examined using light microscopy. RESULTS: An apparent rise in the hearing thresholds of the groups Ia and Ib was not observed. However, there was an apparent rise in the hearing thresholds of the group IIa, which supports ototoxicity. According to histopathology results, there weren't any pathological findings in groups Ia and Ib and did not display special features, but a neurotoxic effect was observed in group II. CONCLUSION: Our study shows that the H202-Ag used in pool water disinfection can have ototoxic and neurotoxic effects, particularly at high concentrations.

Relationships between facial canal dehiscence and other intraoperative findings in chronic otitis media with cholesteatoma.

OBJECTIVE: We investigated the relationship between facial canal dehiscence and intraoperative middle ear and mastoid findings in patients operated on for cholesteatoma. METHODS: We examined retrospectively 334 patients who had been operated on for cholesteatoma in Izmir Katip Celebi University, Ataturk Research and Training Hospital, ENT Clinic, between April 1997 and April 2010. The patients were examined for facial canal dehiscence according to age, gender, side of the ear, surgery type, first or revision surgery, localization of the facial canal dehiscence, spread of the cholesteatoma, with the presence of lateral semi-circular canal (LSCC) fistula and any defect in the ossicle chain, and destruction in the posterior wall of the external auditory canal(EAC). RESULTS: Of the patients, 23.6% had facial canal dehiscence and detected most commonly in the right ear 28.9% and tympanic segment, 83.5%. Facial canal dehiscence was found to be 24.2-fold more common in patients with LSCC fistula and 4.1-fold more common in patients with destruction in the posterior wall of the (EAC). In patients located cholesteatoma in tympanic cavity+antrum and the tympanic cavity+all mastoid cells and with incus and stapes defect, increased incidence of dehiscence. Age, first or revision operation and canal wall down tympanoplasty (CWDT) or canal wall up tympanoplasty (CWUT) did not affect the incidence of dehiscence. CONCLUSIONS: That the likelihood of facial canal dehiscence occurrence is increased in patients with LSSC fistulas, destruction in the posterior wall of the EAC, or a stapes defect is important information for surgeons.
