The Clinic for Otorhinolaryngology and Maxillofacial Surgery at the University Clinical Center of Serbia celebrates its 100th anniversary in 2024. Established in 1924, the clinic has significantly contributed to the development of otorhinolaryngology in Serbia, keeping pace with European advancements. Its origins trace back to the early 1870s with Dr. Jovan Jovanović Zmaj, a physician who pioneered laryngoscopy in the country, and to Dr. Vladan Đorđević in 1871. Both were pioneers of laryngoscopy – Dr. Jovanović Zmaj in Novi Sad, and Dr. Đorđević in Belgrade. The clinic initially operated at the General State Hospital in Belgrade, before expanding and relocating multiple times. It has continually grown, introducing cutting-edge treatments and technologies, including endoscopic procedures, pediatric care, and advanced head and neck surgeries. Today, the clinic has 115 beds, six operating rooms, and specialized departments, offering comprehensive care in otorhinolaryngology and maxillofacial surgery. With a strong educational focus, it trains future medical professionals and continues to lead innovations in ENT and maxillofacial surgery. The clinic’s strategic goals include modernizing equipment and expanding capacities, aiming to maintain its position as a leader in the field. © 2025, Serbia Medical Society. All rights reserved.

COVID-19 infection is associated with a variety of neurological manifestations. Since the inner ear is vulnerable to viruses, sensorineural hearing loss (SNHL) has been reported to occur following SARS-CoV-2 infection. We present here two cases of profound SNHL following SARS-CoV-2 infection. Pure-tone audiograms confirmed profound SNHL. The tympanogram and Auditory Brainstem Responses showed no abnormal symptoms. MRIs and CTs identified some changes but no significant anatomical nor physiological manifestations explaining the obvious cause for hearing loss. High doses of oral corticosteroids with additional conservative therapy were given with no therapeutic response, and therefore, cochlear implant surgery was performed. One case was bilaterally treated, and the other one received an implantation on one side. Both surgeries were carried out without intra- nor postoperative complications. Interestingly, in both cases, advanced fibrotic tissue was found during surgery. Both cases reported successful rehabilitation and are satisfied with their new sound perception following cochlear implantation. © 2023 by the authors.

Introduction. Late metastases of malignant tumors in the temporal bone are very rare lesions. They can be asymptomatic for a long time and usually manifest themselves in the form of hearing loss, dizziness, tinnitus, and paralysis of the facial nerve. Modern radiological diagnostics and explorative surgery with biopsy are essential for diagnosis. Case report. We present a rare and unusual case of a 66-year-old female patient with facial nerve paralysis that appeared as the first sign of metastatic breast cancer in the temporal bone 10 years after treatment. A sudden hearing loss and dizziness occurred six months later, and the value of CA 15-3 was elevated. Scintigraphy pointed to susceptible metastatic deposits of the axial skeleton without lesions in the temporal bone. Finally, repeated computed tomography revealed osteolytic changes in the temporal bone six months after that. Immunohistochemical analysis of mastoid tissue samples confirmed that it was a breast cancer metastasis. One year after palliative radiotherapy and oral hormone therapy, a patient had a good general condition with a better function of the facial nerve. Conclusion. A high degree of clinical suspicion sometimes requires repeated radiological diagnostics in order to detect osteolytic metastatic changes in the temporal bone but also in other bone structures within the hematogenous dissemination of the malignant disease. © The Author(s) 2022.

Introduction. Intracranial complications of otitis media still occur, despite great progress in the treatment of all forms of inflammation. These are serious conditions which are still life-threatening and require a fast and accurate diagnosis and an adequate treatment. We present an illustrative case of an acute, foudroyant, pneumococcal, suppurative otitis media with infection spreading into endocranium and development of meningoencephalitis and otic hydrocephalus. Case report. A 6-year-old girl was admitted to the University Children's Clinic in Belgrade, Serbia, because of fever, headache, vomiting and disorder of consciousness. Computed tomography scan of the endocranium and temporal bone revealed brain edema and hypodense content in the left mastoid and tympanic cavity. The diagnosis of acute otitis media with meningoencephalitis was made and we started with intensive antibiotic treatment. Lumbar puncture and hemoculture confirmed a pneumococcal infection. Otosurgical treatment was conducted, too, due to an inadequate reaction to the conservative treatment. Firstly, left mastoidectomy with the implantation of a ventilation tube was performed, followed by a radical tympanomastoidectomy, because there was no improvement. Three weeks after the second operation, a magnetic resonance imaging of the endocranium was performed and an otic hydrocephalus was diagnosed. A neurosurgical operation was performed on the same day with the setting of the ventriculoperitoneal shunt. Conclusion. Intracranial complications of acute otitis media in children are extremely rare and they require a multidisciplinary treatment. Surgical treatment of the ear should not be postponed and the choice of the type of otosurgical intervention should be individually adapted. Audiological and neurological complications of the disease are frequent and they further prolong and impair the treatment. © 2021 Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.

Purpose: Otitis media with effusion (OME) associated with Samter’s triad (ST) is a difficult entity to treat. The aim of study was an investigation of the middle ear and nasal production of inflammatory mediators (IM) in patients with ST and analysing differences between them and controls. Methods: Prospective case–control study. Nineteen patients with OME (five had allergic rhinitis, four had nasopharyngeal lymphoid hyperplasia, five had no evident sino-nasopharyngeal disease and five had confirmed ST) and 15 healthy participants were included. The concentrations of IM interleukin–1 beta (IL-1β), interferon-alpha 2 (IFN-α2), interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), monocyte chemoattractant protein-1 (MCP-1), IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-18, IL-23 and IL-33 were measured in nasal and middle ear secretions. Results: There was a difference that was close to a level of statistical significance only for IL-1β levels in middle ear fluid (p = 0.052) between the ST subgroup and the other patients with OME. Also, we found a significant difference for IL-23 in nasal secretions between these subgroups (p = 0.040), whereas the difference in nasal fluid IL-33 was close to a level of statistical significance (p = 0.052). There was a significant difference in nasal concentrations of IL-1β, IFN-α2, MCP-1, IL-8, IL-18 and IL-33 (p < 0.001, p = 0.005, p = 0.008, p = 0.011, p = 0.011 and p = 0.011, respectively) between the OME group and the healthy subjects. There were significant positive correlations between concentrations of IL-1β, IFN-α2, IFN-γ, TNF-α, MCP-1, IL-17A, IL-18 and IL-33 (p < 0.001, p < 0.001, p = 0.002, p = 0.028, p < 0.001, p < 0.001, p < 0.001 and p < 0.001, respectively) in nasal and middle ear secretions. Conclusion: This preliminary report showed some differences in IM production between the patients with OME associated with ST and those without it. Our results suggest a uniformity of the production of nasal and middle ear IM and supported the concept of a united airway respiratory disease. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.

Introduction. A hibernoma is a rare benign tumor derived from vestigial remnants of brown adipose tissue. In neonates this tissue makes up about 5% of the body mass and its amount greatly decreases after birth, persisting only in scattered subcutaneous areas. In rare cases, brown fat continues to grow leading to a hibernoma that may be located in the head and neck. We present an illustrative case of a large hibernoma of the neck with infraclavicular extension and discuss about diagnostic and treatment difficulties. Case report. A 29-year-old male presented with large, slowly progressive, painless neck mass that was noticed 6 months earlier. Computed tomography (CT) and magnetic resonance (MR) showed a well-vascularized, soft tissue tumor of the lateral region of the neck and supraclavicular fossa with extension below clavicle. Treatment included arterial embolization followed by challenging surgical removal of the tumor. Dissection was performed at III, IV and V levels of the neck, making complete resection possible without the tumor fragmentation or major blood vessels and cranial nerves injuries. The final diagnosis of the hibernoma was made by histopathological analysis. The patient had no signs of recurrence during three-year follow-up. Conclusion. Although the CT scan and MR may raise the suspicion, hibernoma is definitely diagnosed by a pathologist. It is very important to exclude the malignant processes, foremost liposarcoma. The tumor fragmentation during surgery should be avoided because the high vascularity of the tumor tissue carries a substantial risk for hemorrhage. Our experience with preoperative embolization and complete tumor resection in this case showed positive impact on the final outcome. © 2019, Inst. Sci. inf., Univ. Defence in Belgrade.

Introduction Acute otitis media is a very common disease in the early childhood age, with typical symptoms such as otalgia and fever. Otogenic complications are divided into extracranial and intracranial. Although the introduction of antibiotics has significantly reduced the incidence of intracranial complications, they are still present. Clinical picture usually develops fast, with the predominance of neurologic symptoms. Case outline An 11-year-old boy was admitted to a tertiary health care children’s hospital because of fever, agitation, altered behavior and disorder of consciousness. Based on the anamnesis, clinical examination, CT, MRI, and lumbar puncture, it has been established that it is a case of meningoencephalitis as complications of acute otitis media. Besides intense antibiotic and symptomatic therapy, surgical treatment too was conducted as well. Firstly, mastoidectomy with the implantation of ventilation tube was done, followed by radical tympanomastoidectomy, because there was no improvement. The treatment was followed by numerous complications, such as toxic hepatitis, mycoplasma pneumoniae infection, and hemolytic anemia. The treatment lasted for 71 days, and the patient was discharged from the hospital in a good general condition, without the focal motor failure. Conclusion Meningoencephalitis is unusual and rare complication of acute otitis media that requires urgent diagnostic procedure and multidisciplinary approach to the treatment. Surgical treatment of the ear that caused complications should not be postponed, and the choice of surgical method must be adapted to each patient individually. Hospital treatment of these patients is often prolonged and auditory and neurological sequelae are substantial and require long-term treatment. © 2019 Serbia Medical Society. All rights reserved.

Intraoperative hypertension (IOHTA) during neck surgery is undesirable because this type of surgery has a propensity to bleed profoundly even in normotensive anesthesia. The purpose of our study was to detect predictors of IOHTA in patients undergoing neck surgery. This single center retrospective study included 880 adult patients who underwent neck surgery under general anesthesia. The impact of gender, age, comorbidity, difficult tracheal intubation, anesthesia duration, and induced hypotension on IOHTA was studied. IOHTA was present in 57 (6.7%) patients. The highest incidence of IOHTA was recorded in patients with ASA 4 status and those with Cormack-Lehane grade 4,: (22.2% and 21.4%, respectively). Significantly more patients with hypertension, hyperlipoproteinemia and ventricular extrasystoles had IOHTA compared with patients without these comorbidities. Statistically significant predictors of IOHTA were age (OR 1.438; 95% CI 1.144-1.808; p=0.002), cardiac arrhythmia (OR 1.702; 95% CI 1.129-2.566; p=0.011), Cormack-Lehane grade (OR 1.407; 95% CI 1.054-1.878; p=0.020), and duration of anesthesia (OR 1.005; 95% CI 1.001-1.008; p=0.005). The risk of IOHTA occurrence was lower in patients with induced hypotension (OR 0.024; 95% CI 0.003-0.185; p=0.000). During neck surgery, special attention is needed in patients of older age, those with cardiac arrhythmia, difficult intubation, and longer anesthesia duration because they are at risk of IOHTA. © 2023, Dr. Mladen Stojanovic University Hospital.

Introduction. The elongated styloid process is a very rare clinical entity. In most cases it is asymptomatic, but also could cause Eagle’s syndrome. We presented a rare case of the anatomic variation of styloid process and its clinical implication. Case report. In the left tonsillar fossa an unexpected bony structure was found during the routine tonsillectomy on a 16-year-old female patient. Computed tomography showed the elongated styloid process. No further treatment was necessary because it was asymptomatic in the follow-up period. Conclusion. The elongated styloid process is a very rare condition, but physicians should be aware of it and keep it in mind in order to make the diagnosis in patients with suggestive symptoms. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.
