IgG4-Related Disease Involving the Ear: A Case Report.

IgG4-related disease is a chronic inflammatory disease with widespread clinical presentation. It mimics various malignant, infectious, and inflammatory conditions, leading to confusion in diagnosis and management. Otological manifestations, though relatively rare, can lead to significant complications. A 45-year-old male with a recent history of ventilation tube placement in the right ear presented with a sensation of imbalance associated with profound hearing loss. He was managed in line of acute otitis media with labyrinthitis with steroids and antibiotics and removal of the ventilation tube. He returned in one week and presented with right-sided lower motor neuron-type facial paresis. Computed tomography images of the temporal bone showed a soft tissue density lesion in the right middle ear cavity extending to the mastoid antrum. He underwent a right cortical mastoidectomy with decompression of the facial nerve. Histopathology and immunohistochemistry of granulation tissues from the middle ear and the mastoid revealed evidence suggestive of probable IgG4 disease. IgG4-related disease is a relatively new entity, and its pathogenesis has not been properly understood. IgG4 subclass has been involved in this disease resulting in fibro-inflammatory conditions leading to tumor-like masses or fibrosis of the affected organs. Treatment includes glucocorticoids and immunosuppressant medications.

Standard operating procedure and surgical technique innovation in fully endoscopic microvascular decompression for trigeminal neuralgia: technical note on 189 patients.

Microvascular decompression (MVD) is a well-established and effective treatment for primary trigeminal neuralgia (TN). Endoscopy has been implemented to provide a comprehensive view of neurovascular conflict and minimizes the damages of brain retraction during MVD. To preliminarily evaluate the surgical safety and efficacy of fully endoscopic microvascular decompression (EMVD) for primary TN with surgeon performing two-hand manipulation and assistant holding endoscope. Retrospective clinical analysis of 189 patients with primary TN underwent EMVD between June 2019 and August 2022 was performed. By analyzing the intraoperative situation, the outcomes of postoperative symptoms and the main complications, we evaluated the reliability and effectivity of the operative technique in the treatment of primary TN. We summarized the standard operating procedure of EMVD for primary TN with surgeon performing two-hand manipulation and assistant holding endoscope. In addition, acicular bipolar electrocoagulation technique was developed to handle venous compression. During the follow-up period, good pain relief was achieved in 178 patients (94.2%) and recurrence of pain was observed in 4 patients (2.1%). Postoperative temporary complications included trigeminal dysesthesias (7 patients, 4.8%), cerebrospinal fluid leak (2 patients, 1.1%), hearing difficulty (3 patient, 1.6%), facial paresis (2 patients, 1.1%) and vertigo (5 patients, 2.7%). There were no cases of intracranial hemorrhage, cerebellar swelling and death. This EMVD technique is reliable and effective, and can be used as a routine surgical procedure for primary TN.

The Clinical and Surgical Characteristics of Parotid Tumors with Parapharyngeal Space Involvement-A Multicenter Experience of the Polish Salivary Network.

Backgrounds/Objectives: Parotid gland tumors (PGTs) with parapharyngeal space (PPS) involvement have a specific clinical course and they can be a great challenge for surgeons, especially due to more difficult approaches and the risk of serious complications. The aim of this study is to present the characteristics of PGTs with PPS involvement. Methods: Retrospective, multicenter analysis of 1954 primary PGTs from 5 years (2017-2021) was performed. Comparative analysis was performed between groups with and without PPS involvement and included the following clinical and histopathological data: age, sex, place of residence, tumor size, FNAC result, percentage of malignant tumors, histological diagnosis, radicality of resection, and postoperative facial nerve (FN) dysfunction. Results: PPS involvement was found in 114 patients (5.83%). Secondary tumors affecting the deep lobe or the entire gland were predominant (46 and 60 cases, respectively). In a univariate analysis of tumors with and without PPS involvement, statistically significant differences were found in their size > 4 cm (12.97% vs. 37.72%), percentage of malignant tumors (7.12% vs. 17.55%), incidence of Warthin Tumors (WTs) (43.58% vs. 24.56%), percentage of R1 resection (5.53% vs. 12.50%), and rate of FN paresis (17.15% vs. 53.34%). Multivariate analysis showed that tumors with PPS involvement were statistically significantly characterized by larger size (tumors > 4 cm were 2.9 times more frequent), 2 times less frequent occurrence of WTs, and 1.6 times higher risk of FN paresis. Conclusion: PGTs with PPS involvement show certain clinical and histological differences and require more complex surgical accesses. Therefore, they cannot be treated as "ordinary" tumors occupying the deep lobe.

Surgical and radiosurgical outcomes for Koos grade 3 vestibular schwannomas.

This study aimed to reveal the preferred initial treatment for Koos grade 3 vestibular schwannomas (VS). We performed a two-institutional retrospective study on 21 patients with Koos grade 3 VS undergoing resection at Yokohama Medical Center and 37 patients undergoing radiosurgery at Yokohama Rosai Hospital from 2010 to 2021. Tumor control, complications, and functional preservation were compared. The median pre-treatment volume and follow-up duration were 2845 mm3 and 57.0 months, respectively, in the resection group and 2127 mm3 and 81.7 months, respectively, in the radiosurgery group. In the resection group, 16 (76.2%) underwent gross total resection, and three patients (14.3%) experienced regrowth; however, no one required additional treatment. In the radiosurgery group, the tumor control rate was 86.5%, and three cases (8.1%) required surgical resection because of symptomatic brainstem compression. Kaplan-Meier analyses revealed that tumors with delayed continuous enlargement and large thin-walled cysts were significantly associated with poor prognostic factors (p = 0.0027, p < 0.001). The pre-radiosurgery growth rate was also associated with the volume increase (p = 0.013). Two cases (9.5%) required additional operation due to complications such as post-operative hematoma and cerebrospinal fluid leaks in the resection group, whereas temporary cranial neuropathies were observed in the radiosurgery group. Two patients (9.5%) had poor facial nerve function (House-Brackmann grading grade 3) in the resection group, while no one developed facial paresis in the radiosurgery group. Trigeminal neuropathy improved only in the resection group.Radiosurgery can be considered for the treatment of Koos grade 3 VS for functional preservation. However, resection may also be considered for patients with severe trigeminal neuropathy or a high risk of volume increments, such as large thin-walled cysts and rapid pre-treatment growth.

Severely complicated ear infection in a patient treated with ixekizumab: a case report.

We report a case of a severe ear infection in a 35-year-old man treated with ixekizumab for psoriasis. Ixekizumab is a humanized monoclonal antibody that selectively prevents the interaction between interleukin 17A and its receptor. Biologicals like ixekizumab are used to achieve symptom relief in autoimmune diseases including psoriasis. Unlike the mild upper respiratory tract infections usually described as side-effects of this treatment, we report a case of a patient who presented with a severe otitis media, complicated with a facial paresis and nasopharyngeal abscess. To the best of our knowledge, this is the first case presenting a severe, complicated ear infection as a possible side effect of ixekizumab. We conclude that when using ixekizumab, vigilance for upper airway infections is needed and if necessary, interruption of therapy should be considered. However, further research is needed to confirm this hypothesis.

Pituitary germinoma after resection of a mature third ventricular teratoma: illustrative case.

Metachronous intracranial germ cell tumors (iGCTs)-unrelated, histologically different iGCTs occurring at different time points-occurring within the same patient remain a rarity. Herein, the authors report such a case and discuss the literature and potential pathophysiological mechanisms leading to this phenomenon. A 9-year-old boy presented with new-onset impaired balance, headaches, nausea, visual disturbances, and left facial paresis. Magnetic resonance imaging (MRI) scans revealed a suspected pineal region teratoma originating from the pineal gland with consecutive obstructive hydrocephalus. A mature teratoma was diagnosed and resected. Postoperative recovery was good, and the patient could return to his normal daily activities. However, a new, slowly progressive lesion in the sellar region with an enlarged infundibular stalk was detected on follow-up MRI 3.5 years after initial pineal region teratoma resection. Biopsy revealed a newly developed pure germinoma. The patient was treated with radiotherapy plus chemotherapy and remained relapse free at the last follow-up. Sixteen other cases have reported a surgically resected primary mature teratoma, wherein patients developed metachronous germinomas during follow-up. Different theories try to elaborate this phenomenon, yet none can completely account for it. Although rare, metachronous iGCT is a phenomenon neurosurgeons should be aware of. In patients treated for iGCT, close long-term clinical, imaging, and laboratory follow-up is recommended. https://thejns.org/doi/10.3171/CASE2443.

Radiofrequency thermocoagulation as a treatment for hemifacial spasm: long-term follow-up and management of recurrences

BackgroundRadiofrequency thermocoagulation (RFT) is a treatment used to relieve symptoms of cranial nerve disorders. The current study is the first to describe the results of hemifacial spasm (HFS) patients with a history of repeated RFT in the second-largest consecutive single-center patient series with long-term follow-up.MethodThis retrospective study was conducted in the largest hospital district in Finland (Helsinki and Uusimaa). Consecutive HFS patients who had an RFT to treat HFS in the Hospital District of Helsinki and Uusimaa between 2009-2020 were included.ResultsEighteen patients with 53 RFTs were identified from the medical records. 11 (61 %) patients had repeated RFTs, and the mean number of RFTs per patient was 3.33 (3.29 SD). The mean follow-up was 5.54 years (7.5 SD). 12 (67 %) patients had had microvascular decompression (MVD) before RFT.Patients were satisfied with the results after 87 % of RFTs. Relief of the twitching of the face lasted 11.27 months (11.94 SD). All patients had postoperatively transient facial paresis. Postoperative paresis lasted a mean of 6.47 months (6.80 SD). The depth of paresis was postoperatively typically moderate (36.54 %, House Brackmann III). 23.08 % had mild paresis (House-Brackmann II), 23.08 % had moderately severe dysfunction (House-Brackmann IV), 9.62 % had severe dysfunction, and 7.69 % had total paralysis of the facial muscles (House-Brackmann VI). Duration of relief in the face twitching (p 0.002) and temperature at the final coagulation point (p 0.004) were statistically significant predictors of satisfaction with the RFT results.ConclusionsRFT can be used to treat recurrences of HFS repeatedly. It provides symptom relief for around 11 months, lasting four times longer than with botulinum toxin injections. Patients are satisfied, although an RFT produces transient, sometimes even severe, facial paresis.

MAJOR SALIVARY GLAND TUMORS: SINGLE INSTITUTION EXPERIENCE

IntroductionThe study analyses the occurrence and treatment outcomes of tumors of the major salivary glands in our patients.Material and methodsBetween 2019 and March 2023, a total of 182 salivary gland surgeries were conducted at our clinic. Of these, 111 were on females aged 18 to 76 years, and 71 on males aged 18 to 82 years. Diagnosis comprised a medical history, otolaryngological physical examination, ultrasonography (USG), fine-needle aspiration (FNA) biopsy of tumor, laboratory tests (CBC, CRP), and contrast-enhanced computed tomography (CECT) or magnetic resonance imaging (MRI).ResultsPredominantly (176 patients), benign tumors and neoplasms were found in the parotid salivary gland. Histopathology most commonly revealed pleomorphic adenoma (PA, 74 cases) and Warthin’s tumor (WT, 70 cases). Other benign tumors and neoplasms made up only 18% of cases. Malignant neoplasms were only identified in the parotid salivary gland in 3.3% of cases; these were diagnosed as epithelial-myoepithelial carcinoma, adenoid cystic carcinoma, acinic cell carcinoma, mucoepidermoid carcinoma, and ductal carcinoma.ConclusionsIn our dataset, most patients with tumors of the major salivary glands were operated on at ages above 60 years. A low incidence of malignant tumors and a high incidence of WT of the large salivary glands were observed. The main postoperative complication was facial nerve paresis in 7.6% of cases.

Expanding hematoma with facial nerve palsy: an unusual complication of mandibular fracture

The mandible is one of the most commonly fractured facial bones, along with the nasal and zygomatic bones. The most common cause of fracture is trauma, such as a motor vehicle accident, a physical altercation, an industrial accident, a fall, or a contact sport injury. Because of its position and the complex anatomy and environment surrounding it, the mandible is extremely vulnerable and often breaks when a traumatic injury is made to the face. Complications of mandible fractures can range from 7 to 29%, depending on the severity of the injury, the location of the injury, and the number of areas affected. The most frequently encountered complications include infection, hardware failure, osteomyelitis, non-union, mal-union, and wound dehiscence. Here, we report an unusual complication of an expanding hematoma with left sided facial nerve paresis that resulted after 2 months of mandible fracture.

Problems of treating facial nerve paresis after removal of vestibulocochlear neurinoma

Surgical treatment of facial paralysis after removal of tumors of the posterior cranial fossa and lateral part of the base of the skull remains a relevant issue and one of the most difficult problems in modern medicine and neurosurgery. Severe dysfunction of the facial nerve, accompanied by cosmetic, functional, and psychological disorders, is the cause of social maladjustment of patients. Based on current literature, the article provides an overview of various methods of surgical treatment of this pathology aimed at restoring facial expressions and symmetry.

Oral Health-Related Quality of Life in Rare Disorders of Congenital Facial Weakness.

Congenital facial weakness (CFW) encompasses a heterogenous set of rare disorders presenting with decreased facial movement from birth, secondary to impaired function of the facial musculature. The aim of the present study is to provide an analysis of subject-reported oral health-related quality of life (OHRQoL) in congenital facial weakness (CFW) disorders. Forty-four subjects with CFW and age- and sex- matched controls were enrolled in an Institutional Review Board (IRB)-approved study. Demographic data, medical and surgical history, comprehensive oral examination, and the Oral Health Impact Profile (OHIP-14) were obtained. Compared to unaffected controls, subjects with CFW had higher OHIP-14 scores overall (mean ± SD: 13.11 ± 8.11 vs. 4.46 ± 4.98, p < 0.0001) and within five of seven oral health domains, indicating decreased OHRQoL. Although subjects with Moebius syndrome (MBS) were noted to have higher OHIP-14 scores than those with Hereditary Congenital Facial Paresis (HCFP), there was no significant correlation in OHIP-14 score to age, sex, or specific diagnosis. An increase in OHIP-14 scores in subjects was detected in those who had undergone reanimation surgery. In conclusion, subjects with CFW had poorer OHRQoL compared to controls, and subjects with MBS had poorer OHRQoL than subjects with HCFP. This study provides better understanding of oral health care needs and quality of life in a CFW cohort and suggests that guidelines for dental treatment are required.

Approaches to the Management of Synkinesis: A Scoping Review.

Postparalysis facial synkinesis (PPFS) can develop in any facial palsy and is associated with significant functional and psychosocial consequences for affected patients. While the prevention of synkinesis especially after Bell's palsy has been well examined, much less evidence exists regarding the management of patients with already established synkinesis. Therefore, the purpose of this review is to summarize the available literature and to provide an overview of the current therapeutic options for facial palsy patients with established synkinesis. A systematic literature review was undertaken, following the Preferred Reporting Items of Systematic Reviews and Meta-analyses 2020 guidelines. MEDLINE via PubMed and Cochrane Library were searched using the following strategy: ([facial palsy] OR [facial paralysis] OR [facial paresis]) AND (synkinesis) AND ([management] OR [guidelines] OR [treatment]). The initial search yielded 201 articles of which 36 original papers and 2 meta-analyses met the criteria for inclusion. Overall, the included articles provided original outcome data on 1,408 patients. Articles were divided into the following treatment categories: chemodenervation (12 studies, 536 patients), facial therapy (5 studies, 206 patients), surgical (10 studies, 389 patients), and combination therapy (9 studies, 278 patients). Results are analyzed and discussed accordingly. Significant heterogeneity in study population and design, lack of control groups, differences in postoperative follow-up, as well as the use of a variety of subjective and objective assessment tools to quantify synkinesis prevent direct comparison between treatment modalities. To date, there is no consensus on how PPFS is best treated. The lack of comparative studies and standardized outcome reporting hinder our understanding of this complex condition. Until higher quality scientific evidence is available, it remains a challenge best approached in an interdisciplinary team. An individualized multimodal therapeutic concept consisting of facial therapy, chemodenervation, and surgery should be tailored to meet the specific needs of the patient.

From Headache to Melkersson-Rosenthal Syndrome: A Case Report

Melkersson-Rosenthal syndrome is described as a syndrome which associates three cardinal signs: peripheral facial paralysis, facial oedema, and fissured tongue. These signs are rarely all present. A range of other symptoms are associated with its, making the diagnosis difficult. We report a case of a twenty-five-year-old women presented recurrent facial paresis and clinical dry syndrome since several years. The facial paresis was secondarily accompanied by headache. After a complete dermatological examination, a Melkersson-Rosenthal syndrome has been suspected. Several treatments have been tried, reducing the symptoms, without making them disappear. The Melkersson-Rosenthal syndrome is well known, but the characteristic triad is rarely present in its entirety. This syndrome is accompanied by a multitude of other symptoms of neurovegetative origin for the most part, and sometimes with autoimmune disorders, which can induce diagnostic delay and/or misdiagnosis.

Utility and Prognostic Value of Intraoperative Blink Reflex in Trigeminal or Facial Nerve Monitoring in Skull Base Surgeries: A Systematic Review

Blink reflex (BR) is an oligosynaptic reflex that involves the ophthalmic branch of the trigeminal nerve (TN), ipsilateral main sensory and trigeminospinal nuclei, bilateral facial nuclei, and the facial nerves (FNs). Theoretically, as BR tests the function of both TN and FNs simultaneously, it is an ideal tool for monitoring the status of TN and FNs during skull base surgeries. Nevertheless, it has been used only recently in surgeries as the use of anesthesia limits its use. For this systematic review, 2 authors input the search terms [(Blink Reflex) AND (Intraoperative Neuromonitoring OR Neuro Intraoperative Monitoring OR Intraoperative OR NIOM OR IONM) AND (skull base surgery OR Facial Nerve OR Trigeminal Nerve OR Microvascular Decompression OR Hemifacial Spasm)] in MEDLINE through its PubMed interface and other search engines. Articles that fulfilled the inclusion and exclusion criteria were obtained and scrutinized. Seven observational articles with a total of 437 participants were included. All 5 studies that described the use of BR in FN surgery noted that intraoperative BR is beneficial, safe, sensitive, specific, and predictive of outcomes, while 2 articles describing patients with trigeminal neuralgia recommended use of BR in microvascular decompression of TN. Intraoperative BR is a sensitive, specific, and safe monitoring technique that has good predictability of facial paresis and paresthesia among patients undergoing MVD for trigeminal neuralgia and primary hemifacial spasm and patients undergoing cerebellopontine angle tumor resection.

Applying the Full Endoscopic Keyhole Technique to CPA Lesions: A Single-Center Study.

In recent years, endoscopy has become an increasingly common tool used during neurosurgical procedures. However, its application in treating cerebellopontine angle (CPA) lesions has not progressed as rapidly. In this study, the authors present their initial experience with surgically treating CPA lesions using a fully endoscopic keyhole retrosigmoid approach. They conducted a retrospective analysis of clinical data from patients who underwent endoscopic keyhole CPA surgery at their center between May 2017 and April 2022. They provide a comprehensive explanation of this method and an overview of the strategies that have been developed to achieve better clinical outcomes. The study included 107 patients, consisting of 10 cases of vestibular schwannoma, 21 cases of epidermoid cyst, 32 cases of trigeminal neuralgia, and 44 cases of hemifacial spasm. The authors analyzed the clinicodemographic details of the patients. Among the 31 tumor cases, gross total resection was achieved in 25 patients (80.6%), while near-total resection was performed in 6 patients (19.4%). In patients with trigeminal neuralgia, facial pain resolved in 31 out of 32 patients (96.9%). Similarly, facial convulsions disappeared or were relieved in all 44 patients (100%) with hemifacial spasms after the operation. Postoperative complications included facial nerve paresis (n=9, 8.4%), with improvement observed in 6 cases during follow-up, transient facial hypoesthesia (n=3, 2.8%), cerebrospinal fluid rhinorrhea (n=3, 2.8%), transient abducens paresis (n=1, 0.9%), and postoperative hemorrhage (n=1, 0.9%). Endoscopy provides improved deep illumination and, combined with close-up observation, enhances the visualization of structures within the CPA region. The fully endoscopic keyhole technique is a safe and effective method for managing CPA lesions.

Epiphora and Hyperlacrimation as Paradoxical Manifestations of Facial Nerve Injury: Mechanistic Insights.

The incidence of facial nerve paralysis is approximately 30 per 100,000 persons annually. Although it is often idiopathic, as in Bell's palsy, it can also result from infections, trauma, or neoplasms. Facial nerve paralysis may present with partial or total facial paresis, lagophthalmos, denervation of the lacrimal gland, and other ocular abnormalities. While dry eye is a commonly expected outcome of facial nerve injury, some patients may paradoxically experience epiphora and hyperlacrimation. In this review, we examine this phenomenon and its mechanisms in facial nerve injury. Several mechanisms have been proposed for epiphora and hyperlacrimation, including aberrant axonal regeneration, which is known to cause crocodile tears syndrome; ocular irritation due to dry eye, resulting in increased reflex lacrimation due to disruption of the tear film; and impaired drainage of tears caused by paralysis of the orbicularis oculi muscle and malposition of the eyelids. Understanding the pathophysiology of these symptoms is crucial in guiding the management of patients with facial nerve injury. Further experimental and clinical studies focusing on the quantification of tear production and localization of nerve damage will help improve our understanding of the neuroanatomical correlates of this paradoxical manifestation.

Surgical treatment of intermediate nerve neuralgia using intraoperative neurophysiological monitoring

Intermediate nerve neuralgia (INN) is a rare pathology with difficult diagnostics and currently there is no generally accepted surgical management protocol. In this regard, an optimal surgical strategy in this case is a difficult task. The aim was to determine an optimal approach for surgical management of patients with INN using intraoperative neurophysiological monitoring (IONM).The INN was diagnosed in a patient, a vestibulo‑cochlear complex dissection with intermediate nerve sectioning under IONM control of was performed intraoperatively. There was the earache regression, but there were gustatory disorders in the anterior portion on the left side of the tongue in the early postoperative period. In the late postoperative period, a delayed facial nerve paresis and signs of liquorrhea were diagnosed, which were completely regressed after reoperation and medication. The follow‑up period was more than 12 months; a stable regression of otoalgia was achieved. Intermediate nerve sectioning is an effective and common technique for the treatment of patients with INN. IONM improves surgical results and reduces a likelihood of different complications.

Is pre-operative electromyography a reliable tool in differentiating acute and chronic facial palsy? A preliminary evaluation in patients treated with triple innervation facial reanimation

Electromyographic evaluation is a reliable tool for confirming facial palsy and assessing its severity. It allows differentiating facial paresis and paralysis, and further distinguishes acute palsies, still showing muscle fibrillations, from chronic cases. This article aims to show that EMG fibrillations might represent a better criterion to differentiate acute and chronic palsies than the standard 18–24 months’ cut-off usually employed for classification and treatment purposes.We performed a cohort study using the eFACE tool for comparing triple innervation facial reanimation results in patients with EMG fibrillation treated <12 months, 12–18 months, and >18 months from paralysis onset.Patients showed a statistically significant post-operative improvement in all eFACE items, both in the whole sample and in the three groups. Only the deviation from the optimal score for the gentle eye closure item in group 2 didn't reach statistical significance (p = 0.173). The post-operative results were comparable in the three groups, as the Kruskal-Wallis test showed a difference only for the platysmal synkinesis item scores, which were significantly lower in group 3 (p = 0.025).EMG should represent a further tool to wide the group of paralysis patients that could be treated as recent facial palsy patients; Further prospective studies on pre-operative EMG fibrillations might allow for further refinement of the technique selection process.

Cervical approach for prestyloid parapharyngeal pleomorphic adenoma resection

ObjectiveTo describe the key points of cervical resection for prestyloid parapharyngeal pleomorphic adenoma and to discuss the role of modern imaging. ObservationRetrospective case series of 10 patients (4 women and 6 men, age 29–63 years) with prestyloid parapharyngeal pleomorphic adenoma with 2 to 8cm largest diameter on MRI, consecutively resected via a cervical approach between 2000 and 2020 in a French tertiary university referral care center. Seven patients had a minimum 10 years’ follow-up, and one was lost to follow-up before the fifth postoperative year. Peri- and postoperative complications comprised great auricular nerve transection without subsequent symptomatic neuroma (2 patients), associated transoral approach to free the upper pole of the adenoma (2 patients), capsule effraction (3 patients), and hematoma (1 patient). There were no cases of facial paresis or palsy, other cranial nerve impairment, trismus, auriculotemporal or first-bite syndrome. One of the three patients with capsule effraction showed local recurrence at month 17. ConclusionIn agreement with previous reports, the present case series confirmed the role of the cervical approach to resect prestyloid parapharyngeal pleomorphic adenoma, and hence the need to continue teaching it.
