ABSTRACT
Background: We present the case of a patient with solitary fibrous tumor of the masticator space with unusual extension. Case presentation: A 43-year-old woman presented with a painless mass with intraoral extension on the right cheek. The B-scan sonograph and magnetic resonance imaging revealed the extension of the tumor. The biopsy performed under local anesthesia raised the suspicion of a solitary fibrous tumor. Tumor excision included a preoperative tumor embolization. The surgical removal of the tumor included a partial parotidectomy on the right side, insertion of masseteric and temporalis muscle, resection of the middle part of the zygomatic bone and stabilization of the bone with a plate, mobilization of the tumor from the maxillary sinus and the pterygopalatine fossa through an endoscopic approach and an approach via partial resection of the anterior wall of the maxillary sinus after identifying and sparing the infraorbital nerve. Ôhe histological findings confirmed the diagnosis of solitary fibrous tumor. The patient's treatment completed with radiation therapy, and 2.5 years later, there was recurrence in the right temporal area. Conclusion:To our knowledge, this is the second reported case of solitary fibrous tumor arising in the masticator space and the only case with extension intraorally and in the paranasal sinuses. Tumor embolization and complete surgical excision are the most frequently recommended treatments.
ABSTRACT
BACKGROUND: Parotid gland agenesis is a rare, congenital, usually asymptomatic disorder. Until now, only 24 cases with unilateral, incidentally found, parotid gland agenesis have been described. Here, we present the first reported case of an ipsilateral preauricular neoplasm in a patient with unilateral parotid gland agenesis. During surgery, the position of the greater auricular- and facial nerves was documented. Furthermore, we performed the first sialendoscopy for this rare disorder to assess the number of duct branches, which might be indicative of the abundance of parotid tissue. Moreover, we looked for sialendoscopic characteristic features that could aid in identifying these patients in the ambulatory setting. CASE PRESENTATION: A 50-year-old Greek man presented with a painless, slowly enlarging mass in the right parotid space. Magnetic resonance imaging revealed a complete absence of the right parotid gland without accessory parotid tissue. The right parotid gland was replaced by fatty tissue and the radiologist suggested a benign parotid tumor. Fine needle aspiration was indicative of a reactive lymph node. Sialendoscopy revealed only two branches within the right parotid duct. Surgical resection was performed through a conventional lateral parotidectomy. This revealed typical anatomic position of the greater auricular- and facial nerves despite the parotid tissue agenesis. Histopathology revealed a small lymphocytic lymphoma. CONCLUSIONS: Surgeons should feel confident to resect tumors of the parotid space in patients with parotid gland agenesis. Reduced branching observed during sialendoscopy might indicate parotid gland agenesis. Physicians should be even more cautious than usual with the watch and wait strategy in patients with tumors of parotid gland agenesis, since the probability of a tumor being a benign salivary gland tumor might be lower than usual.

The incidence of head and neck cancer (HNC), constituting approximately one in ten cancer cases worldwide, affects approximately 644,000 individuals annually. Managing this complex disease involves various treatment modalities such as systemic therapy, radiation, and surgery, particularly for patients with locally advanced disease. HNC treatment necessitates a multidisciplinary approach due to alterations in patients' genomes affecting their functionality. Predominantly, squamous cell carcinomas (SCCs), the majority of HNCs, arise from the upper aerodigestive tract epithelium. The epidemiology, staging, diagnosis, and management techniques of head and neck squamous cell carcinoma (HNSCC), encompassing clinical, image-based, histopathological and molecular profiling, have been extensively reviewed. Lymph node metastasis (LNM) is a well-known predictive factor for HNSCC that initiates metastasis and significantly impacts HNSCC prognosis. Distant metastasis (DM) in HNSCC has been correlated to aberrant expression of cancer cell-derived cytokines and growth factors triggering abnormal activation of several signaling pathways that boost cancer cell aggressiveness. Recent advances in genetic profiling, understanding tumor microenvironment, oligometastatic disease, and immunotherapy have revolutionized treatment strategies and disease control. Future research may leverage genomics and proteomics to identify biomarkers aiding individualized HNSCC treatment. Understanding the molecular basis, genetic landscape, atypical signaling pathways, and tumor microenvironment have enhanced the comprehension of HNSCC molecular etiology. This critical review sheds light on regional and distant metastases in HNSCC, presenting major clinical and laboratory features, predictive biomarkers, and available therapeutic approaches.

PURPOSE: Pharyngocutaneous fistula (PCF) is a possible complication following total laryngectomy (TL), with a mean incidence of 17%. We intended to investigate the effect of pharyngeal closure type during TL on the prevention of PCF. METHODS: We retrospectively reviewed patients that underwent TL with a horizontal pharyngeal closure over a 10-year period. The frequency of PCF clinically, dysphagia, total oral diet, postoperative dilatation of the neopharynx and voice problems were tabulated. RESULTS: Seventy-seven subjects underwent TL due to laryngeal tumor without pharyngeal extension. Of them, 45 underwent a salvage TL. PCF occurred in 1/77 subjects. The rest of the subjects (76/77) did not develop a PCF, neither in the early nor in the late postoperative phase. All subjects (15/77) that underwent implantation of a voice prosthesis were satisfied with their voice. No subject complained about dysphagia. Every subject achieved total oral diet. CONCLUSION: The horizontal pharyngeal closure is a safe pharyngeal closure technique during TL, reduces PCF rates (< 2%), results in excellent voice rehabilitation and swallowing function, and can also be used during salvage TL instead of a major pectoral flap. This type of closure should be used only in selected patients with laryngeal disease without pharyngeal extension.

BACKGROUND: Transoral pharyngeal surgery is mainly feasible with the use of a microscope or robotic systems. Data about alternative methods, with lower costs and easier availability, are sparse. We intended to examine to what extent the endoscope-holding arm is a suitable alternative to the microscope or robotic systems. MATERIAL AND METHODS: We retrospectively reviewed subjects who underwent pharyngeal tumor resection with the endoscope-holding arm in our university department. RESULTS: We identified 13 subjects who underwent transoral pharyngeal surgery between November 2020 and November 2023. Most subjects presented with an oropharyngeal tumor (6/11 in the lateral wall or tonsil; 4/11 in the tongue base). The oropharyngeal lateral wall or tonsillar tumors were exposed with a standard mouth gag. The tongue-base tumors or hypopharyngeal tumors were exposed with an operating laryngoscope. Advantages over the microscope included an angled view. Advantages over robotic systems included haptic feedback and a faster setup. Advantages over both the microscope and robotic systems included lower costs and easier availability. Visualization with the endoscope was sufficient and similar to that of the microscope. Bimanual action was possible with surgical forceps and a monopolar electrode. CONCLUSIONS: Transoral pharyngeal surgery was feasible with the endoscope-holding arm. The endoscope-holding arm could be a cost-efficient alternative to the microscope or robotic systems.
ABSTRACT
Oral squamous cell carcinoma (OSCC) is a head and neck cancer (HNC) with a high mortality rate. OSCC is developed in the oral cavity and it is triggered by many etiologic factors and can metastasize both regionally and distantly. Recent research advances in OSCC improved our understanding on the molecular mechanisms involved in and the initiation of OSCC metastasis. The key roles of the extracellular matrix (ECM) in OSCC are an emerging area of intensive research as the ECM macromolecular network is actively involved in events that regulate cellular morphological and functional properties, transcription and cell signaling mechanisms in invasion and metastasis. The provisional matrix that is formed by cancer cells is profoundly different in composition and functions as compared with the matrix of normal tissue. Fibroblasts are mainly responsible for matrix production and remodeling, but in cancer, the tumor matrix in the tumor microenvironment (TME) also originates from cancer cells. Even though extensive research has been conducted on the role of ECM in regulating cancer pathogenesis, its role in modulating OSCC is less elucidated since there are several issues yet to be fully understood. This critical review is focused on recent research as to present and discuss on the involvement of ECM macromolecular effectors (i.e., proteoglycans, integrins, matrix metalloproteinases) in OSCC development and progression.

Head and neck cancer (HNC) encompasses a number of malignancies originating in the head and neck area. In patients with HNC, cervical lymph nodes constitute metastatic sites for cancer cells that escape primary tumors. The premetastatic niche (PMN) is a crucial concept in understanding metastatic disease. PMN refers to the microenvironment resulting mainly from primary tumor cells to foster metastatic tumor cell growth at a distant organ. Tumor microenvironment (TME) plays an important part in the pathogenesis of PMN. A significant prognostic factor is the close association between metastases of lymph nodes and organ dissemination in many different malignancies. The nodal premetastatic niche (NPMN) is a particular type of PMN located within the lymph nodes. NPMN formation is specifically important in HNC as regional lymph node metastasis commonly occurs. The formation happens when tumor cells create a supportive microenvironment within lymph nodes, facilitating their survival, growth, spread, and invasion. This complex mechanism involves multiple steps and cellular interactions between the primary tumor and tumor microenvironment. Several extracellular matrix (ECM) macromolecules, cytokines, and growth factors are implicated in this process. The aim of this article is to present the most recent data on the regulation of the lymph node PMN at molecular and cellular levels in HNC, as well as insights with respect to the relationship between primary tumor cells and the microenvironment of lymph nodes, and the formation of NPMN. We also critically discuss on potential targets for preventing or disrupting nodal metastases and identify potential biomarkers for predicting HNC outcomes.

Over the last decades, the field of medicine has witnessed significant progress in artificial intelligence (AI), the Internet of Medical Things (IoMT), and deep learning (DL) systems. Otorhinolaryngology, and imaging in its various subspecialties, has not remained untouched by this transformative trend. As the medical landscape evolves, the integration of these technologies becomes imperative in augmenting patient care, fostering innovation, and actively participating in the ever-evolving synergy between computer vision techniques in otorhinolaryngology and AI. To that end, we conducted a thorough search on MEDLINE for papers published until June 2023, utilizing the keywords 'otorhinolaryngology', 'imaging', 'computer vision', 'artificial intelligence', and 'deep learning', and at the same time conducted manual searching in the references section of the articles included in our manuscript. Our search culminated in the retrieval of 121 related articles, which were subsequently subdivided into the following categories: imaging in head and neck, otology, and rhinology. Our objective is to provide a comprehensive introduction to this burgeoning field, tailored for both experienced specialists and aspiring residents in the domain of deep learning algorithms in imaging techniques in otorhinolaryngology.
ABSTRACT
Purpose: We conducted a phase II randomized noncomparative window of opportunity (WOO) trial to evaluate the inhibition of cellular proliferation and the modulation of immune microenvironment after treatment with olaparib alone or in combination with cisplatin or durvalumab in patients with operable head and neck squamous cell carcinoma (HNSCC). Experimental Design: Forty-one patients with HNSCC were randomized to cisplatin plus olaparib (arm A), olaparib alone (arm B), no treatment (arm C) or durvalumab plus olaparib (arm D). The primary endpoint was to evaluate the percentage of patients in each arm that achieved a reduction of at least 25% in Ki67. Secondary endpoints included objective response rate (ORR), safety, and pathologic complete response (pCR) rate. Paired baseline and resection tumor biopsies and blood samples were evaluated for prespecified biomarkers. Results: A decrease in Ki67 of at least 25% was observed in 44.8% of treated patients, as measured by quantitative immunofluorescence. The ORR among treated patients was 12.1%. pCR was observed in 2 patients. Two serious adverse events occurred in 2 patients.Programmed death ligand 1 (PD-L1) levels [combined positive score (CPS)] were significantly higher after treatment in arms A and D. Expression of CD163 and colony-stimulating factor 1 receptor (CSF1R) genes, markers of M2 macrophages, increased significantly posttreatment whereas the expression of CD80, a marker of M1 macrophages, decreased. Conclusion: Preoperative olaparib with cisplatin or alone or with durvalumab was safe in the preoperative setting and led to decrease in Ki67 of at least 25% in 44.8% of treated patients. Olaparib-based treatment modulates the tumor microenvironment leading to upregulation of PD-L1 and induction of protumor features of macrophages. Significance: HNSCC is characterized by defective DNA repair pathways and immunosuppressive tumor microenvironment. PARP inhibitors, which promote DNA damage and "reset" the inflammatory tumor microenvironment, can establish an effective antitumor response. This phase II WOO trial in HNSCC demonstrated the immunomodulatory effects of PARP inhibitor-induced DNA damage. In this chemo-naïve population, PARP inhibitor-based treatment, reduced tumor cell proliferation and modulated tumor microenvironment. After olaparib upregulation of PD-L1 and macrophages, suggests that combinatorial treatment might be beneficial. Synopsis: Our WOO study demonstrates that preoperative olaparib results in a reduction in Ki67, upregulation of PD-L1 CPS, and induction of protumor features of macrophages in HNSCC.

Nasal chondromas and nasal atypical cartilaginous tumors (or chondrosarcoma grade 1) are very rare chondrogenic tumors. Approximately 150 cases of nasal chondroma and fewer than 50 cases of nasal atypical cartilaginous tumors have been described. We reported a case with nasal chondroma in the right ethmoid area and a case with a nasal atypical cartilaginous tumor of the anterior septum. No chondroma recurrence was noted for 17 years after endoscopic resection. Recurrence was noted for the nasal atypical cartilaginous tumor 36 months after wide surgical excision via midfacial degloving. Revision surgery was performed again via midfacial degloving. Recurrences of nasal chondroma and atypical cartilaginous tumors are extremely rare. The current data indicate adequate surgical excision, in some cases even radical, as the most important parameter to avoid recurrence. For inoperable recurrent cases of atypical cartilaginous tumors, observation may be followed.

Exosomes are nanosized vesicles that are produced in normal and cancer cells, promoting intracellular communication. In head and neck cancer (HNC), exosomes are involved in many undesirable events of cancer development and progression, including angiogenesis, tumor microenvironment (TME) remodeling, invasion, epithelial-to-mesenchymal transition (EMT), metastasis, extracellular matrix (ECM) degradation, and drug resistance. Exosomes are involved in altering the signaling pathways in recipient cells by the cargoes they carry. Proteins, lipids, and nucleic acids such as DNA fragments and RNAs (i.e., mRNAs, miRNAs, and long non-coding RNAs) are carried in the exosomes to promote cell communication. EMT is a critical cellular process in which epithelial cells are forced to become mesenchymal cells by the actions of SNAIL/SLUG, TWIST, and ZEB family transcription factors carried in exosomes that facilitate metastasis. In this critical review, we focused on exosome biogenesis, their cargoes, and their involvement in EMT induction and metastasis during HNC. Insights into exosome isolation and characterization, as well as their key role in ECM remodeling and degradation, are also presented and critically discussed. More importantly, this article addresses the role of exosomes in HNC and drug resistance induced in drug-sensitive cancer cells. In addition, exosomes have a great potential to be used as diagnostic and therapeutic tools. A better understanding on exosome biogenesis, composition, and functions in HNC will aid in developing novel therapeutic strategies to treat HNC, overcome therapy resistance, and avoid metastasis, which is a significant cause of cancer death.
ABSTRACT
BACKGROUND: Laryngopharyngeal reflux may affect people of any age; still, most of the accumulated knowledge concerns adults, and evidence regarding pediatric populations remains relatively restricted. This study aims to review the most recent and emerging aspects of pediatric laryngopharyngeal reflux from the last ten years. It also attempts to identify gaps in knowledge and highlight discrepancies that future research should urgently address. METHODS: An electronic search of the MEDLINE database was conducted, limited to January 2012 through December 2021. Non-English language articles, case reports, and studies that concerned a purely or predominantly adult population were excluded. The information from the articles with the most relevant contribution was initially categorized by theme and subsequently synthesized into a narrative form. RESULTS: 86 articles were included, of which 27 were review articles, eight were surveys, and 51 were original articles. Our review systematically maps the research done in the last decade and provides an updated overview and the current state-of-the-art in this subject. CONCLUSIONS: Despite discrepancies and heterogeneity in accumulating research, evidence gathered so far endorses a need for refining an escalating multiparameter diagnostic approach. A step-wise therapeutic plan appears to be the most reasonable management approach, starting with behavioral changes for mild to moderate, uncomplicated cases and escalating to personalized pharmacotherapy options for severe or nonresponsive cases. Surgical options could be considered in the most severe cases when potentially life-threatening symptoms persist despite maximal medical therapy. Over the past decade, the amount of available evidence has been gradually increasing; however, its strength remains low. Several aspects remain markedly under-addressed, and further adequately powered, multicenter, controlled studies with uniformity in diagnostic procedures and criteria are urgently needed.
ABSTRACT
Nasal masses are a clinical entity with great diversity. They present with various symptoms such as nasal obstruction, facial pain, discomfort, epistaxis, headache, anosmia and visual disturbances. Especially unilateral nasal masses are very suspicious and must be differentiated between benign and malignant lesions. Nasal endoscopy is a weapon in the quiver of otorhinolaryngologists. It is an innovative, quick, direct and inexpensive examination that can be performed even at the otorhinolaryngologist's office. Immediate imaging of lesions within the nasal cavity allows rapid initiation of treatment. This article highlights the importance of correct differential diagnosis of a unilateral nasal mass in a 37-year-old female patient.
ABSTRACT
Hearing loss is commonly encountered by general practitioners. We aimed to evaluate the screening benefit of air conduction pure-tone audiometry over visual analogue scale (VAS) scores for hearing loss. Moreover, we intended to perform the first cross-sectional study in Greece to assess hearing loss with pure-tone audiometry in young adults of the general population. We evaluated Greeks between 15 and 40 years old in a high school in Karditsa, Greece, and a primary health care unit in a nearby community. Subjects filled out a VAS score sheet and underwent pure-tone audiometry in a room without sound isolation, with air conduction only. We named the latter procedure modified pure-tone audiometry (mPTA). Subjects with pathologic results were examined via otoscopy and standardized pure-tone audiometry (sPTA). Of the 286 subjects evaluated, the VAS score revealed 5 subjects (1.7%) with hearing loss. mPTA (100 s duration) doubled this percentage (in total 3.8%; Pearson Chi-Square test; p < 0.001). Based on sPTA, the sensitivity and positive predictive value of the VAS score were 40% and 13%, respectively. For mPTA, they were 100% and 37%, respectively. mPTA filtered out pathologic cases in a proper, rapid, cheap and simple way and may be considered a proper screening method for hearing loss in primary health care.
ABSTRACT
ABSTRACT: Cerebrospinal fluid rhinorrhea is frequently encountered after a fracture of the skull base. Individual fractures of the posterior wall of the frontal sinus after brain injury are uncommon. The authors present a case of a 33-year-old man with a distant history of skull base injury after a traffic accident, 12 years ago. He presented with intermittent rhinorrhea and reported 2 episodes of bacterial meningitis the last 7 years since the injury. Cerebrospinal fluid leakage was confirmed with ß2-transferrin testing. Computed tomography and magnetic resonance imaging revealed a small defect of the posterior and superior wall of the left frontal sinus and an ipsilateral meningoencephalocele.Finally, there was a communication between intracranial space and frontal sinus that caused meningitis.A coronal incision and frontal craniotomy with preservation of anterior pericranium was performed (frontal sinus cranialization using osteoplastic flap). In order to determine the precise margins of the frontal sinus and allow an accurate anterior table bone osteotomy and complete exposure of the sinus, the authors used a coronal view of skull X-ray. Scissors are then used to cut along the margins of the sinus. An "R" is scratched into the right side of template to record orientation. The template was sterilized and brought onto the surgical field and then placed over the left sinusAn external surgical approach (anterior table bone osteotomy) with the modern technique of osteoplastic flap access was performed. An elevator was used to separate the dura from the posterior table along the entire margin of the defect. Meningoplasty (cauterization of the meningoencephalocele) and closure of the osseous defect was followed. The authors repaired the defect of the posterior wall of the left frontal sinus using a combination of underlay and overlay technique. Femoral fascia from right thigh and fibrin glue were placed in order to cover the leak of the posterior wall of the left frontal sinus, respectively.Patients who present with a short or/ and distant history of traumatic brain injury should be evaluated for complication of a cerebrospinal fluid leak.

Retropharyngeal space lipomas (RSLs) comprise a group of very uncommon head and neck benign, soft tissue tumors that originally grow in the retropharyngeal space. They can develop as individual tumors or in the context of syndromic lipomatosis. Symptoms usually arise as expanding RSLs exert pressure on adjacent structures, and clinical manifestations are often atypical and overlapping. Given the rarity of this diagnosis, current evidence is scarce, providing a rather fragmented picture. A literature search was conducted in all major medical databases, without time limitations. Tumors were considered RSLs if a benign lipomatous tumor appeared to develop originally in the retropharyngeal space. Cases with syndromic lipomatosis that demonstrated at least one such tumor involving the retropharyngeal space were included. A total of 52 publications concerning 79 eligible cases were found. Two of these cases concerned patients with Multiple Symmetrical Lipomatosis. A male predominance was found (61.5%, n = 48). Dysphagia (65.2%, n = 43) was by far the most common symptom, followed by snoring (37.9%, n = 25), dyspnoea (34.8%, n = 23) and dysphonia (30.3%, n = 20). The most used imaging modality was Computed Tomography (CT) (64.1%, n = 41). Surgery was the treatment in 73 cases (93.6%). The transcervical was the most selected approach (50.7%, n = 37), followed by the transoral approach (38.4%, n = 28). Complete recovery was reported, following treatment, in 60 cases (75.9%). Retropharyngeal space lipomas are benign tumors with a higher prevalence in male patients. Dysphagia is the most common symptom. Imaging is necessary for diagnosis, with CT scanning being usually sufficient as a single modality test. More than half of the patients in the literature are treated via an external approach. Diminishing of symptoms and full postoperative recovery is the most common outcome.

ABSTRACT
We describe the (anteromedial) partial maxillectomy technique which can be used to address impaired nasal breathing in cases of significant protrusion of the frontal process of the maxilla into the nasal cavity, narrowing the nasal pathway. It fits to nasal physiology avoiding mucosal resection. It can be combined with surgery of the inferior turbinate. The described technique can be used in all forms of rhinoplasty.

PURPOSE: To describe a new technique of surgical treatment of the lip commissure or buccal mucosa carcinomas, where we use local flaps (skin, buccal mucosa) of the sliding type. METHODS: According to the current technique, the ectomy ranges horizontally and in a cuneiform shape towards the side of the buccal cavity, and in the whole thickness of the layer (skin - mucosa), where the neoplastic focus is enclosed. RESULTS: The difference in our technique consists of the following: To the vertical bi-cuneiform part of the wound a horizontal cuneiform part (with the top showing upwards) is added, with extent and width analogous to those of the cancerous injury (tri-cuneiform ectomy). The width of the gap across its horizontal part is larger on the side of the mucosa (continuous line), compared to the one along the side of the skin (punctuated line), since the mucosa, as a more versatile tissue, can be sutured easily, in contrast to the buccal skin, which is of greater thickness and shows lack of versatility, so that it can be pulled on with difficulty in order to be sutured. The planning of the injury, according to our described technique, facilitates the broad ectomy of the intraoral injuries in the area of the lip commissure and the buccal mucosa, with immediate suture of the flaps (buccal and skin gap), and the occlusion of the wound by primary intention. CONCLUSIONS: Using this specific technique, in the cases of extended injuries infiltrating the skin or the subcutaneous tissue, the harming use of transposition (sliding or free) flaps is avoided.

ABSTRACT
A sinus pneumocele is a rare entity caused by obstruction of a paranasal sinus ostium. It is characterised by dilation and expansion of the sinus, with subsequent bony erosion. The most probable mechanism is air trapping in the paranasal sinus, via a one-way valve mechanism. The case presented concerns a 68-year-old Caucasian man, with recurrent episodes of acute rhinosinusitis. Clinical examination and subsequent imaging of the face, revealed a large pneumocele of the right frontal sinus that significantly eroded the posterior sinus wall. A large mucocele of the right maxillary sinus was also noted, extending to the middle meatus, causing full obstruction of the ostiomeatal complex. Endoscopic sinus surgery was performed, the mucocele was removed and the pneumatisation pathway of the frontal sinus was restored. The patient reports full resolution of symptoms and shows no evidence of recurrence, 6 months postoperatively.
