Metachronous Cutaneous Melanoma Metastases of the Left Anterior Paranasal Sinuses and the Right Nasopharynx That Were Treated Surgically: A Case Report With Literature Review.

Metastases of cutaneous melanoma to the paranasal sinuses and nasopharynx are considered rare. We reported the case of a patient with cutaneous melanoma metastasizing to the left anterior infundibulum and seven months later to the right nasopharynx that was successfully treated by endonasal endoscopic surgery as a single treatment modality. No adjuvant radiotherapy was performed.

Solitary Fibrous Tumor of the Masticator Space with Unusual Extension: a Case Report.

We present the case of a patient with solitary fibrous tumor of the masticator space with unusual extension. 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.

Lymphoma presenting as preauricular tumor in unilateral parotid gland agenesis: a case report and review of literature.

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.

Insights into metastatic roadmap of head and neck cancer squamous cell carcinoma based on clinical, histopathological and molecular profiles.

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.

Unilateral Nasal Mass Mimicking Tumor in a Young Patient: The Value of Differential Diagnosis.

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.

The Benefit of Air Conduction Pure-Tone Audiometry as a Screening Method for Hearing Loss over the VAS Score.

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.

Matrix-based molecular mechanisms, targeting and diagnostics in oral squamous cell carcinoma.

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.

Deep Learning Techniques and Imaging in Otorhinolaryngology-A State-of-the-Art Review.

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.

The interplay between tumor and nodal microenvironments for the formation of nodal premetastatic niche in head and neck cancer.

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.

Phase II Window Study of Olaparib Alone or with Cisplatin or Durvalumab in Operable Head and Neck Cancer.

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.

Nasal chondrogenic tumors: Case reports of primary chondroma and recurrence of atypical cartilaginous tumor (chondrosarcoma grade I) with review of the literature.

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.

The Role of Exosomes in Epithelial-to-Mesenchymal Transition and Cell Functional Properties in Head and Neck Cancer.

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.

Pediatric Laryngopharyngeal Reflux in the Last Decade: What Is New and Where to Next?

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.

Retropharyngeal Space Lipomas. A Systematic Review of the Reported Cases in the Literature.

Unlabelled: 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.

A Clinical Case of Delayed Posttraumatic Frontal Sinus Cerebrospinal Fluid Leakage Management Via External Surgical Approach.

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.

Fourteen cases of acute invasive fungal rhinosinusitis: is there a place for less aggressive surgical treatment?

Purpose: Acute invasive fungal rhinosinusitis (AIFRS) is a rare, fulminant, angio-invasive infection with high mortality rate. Treatment of AIFRS includes aggressive surgical debridement combined with antifungal agents and treatment of the underlying disease. The aim of this study is to report our experience with this often fatal disease and estimate the long-term survival of AIFRS patients with more conservative surgery.

The Rhinoconjunctivitis Quality of Life Questionnaire and its modified short version validation in adults and children with allergic rhinitis.

Objective: This study aimed to develop the Greek versions of the Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire for adult and pediatric populations, discuss their differences and detect the impact of age and gender on quality of life questionnaire results.

Method: Ninety-eight patients with allergic rhinitis participated. Quality of Life evaluation was made by two generic (Short Form-36 and Beck Depression Inventory) and two disease-specific questionnaires (Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire).

Palatine tonsil metastasis of cecal mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN): A unique case.

This case demonstrates the importance of understanding that patients with malignant neoplasms may exhibit metastases in unexpected sites and illustrates the necessity of a thorough clinical examination and pathologic correlation.

Partial Maxillectomy for the Improvement of Nasal Obstruction Can Be Combined with Septorhinoplasty.

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.

Reconstructing carcinoma of the lip commissure and buccal mucosa: an oncosurgical alternative approach.

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).

Frontal sinus pneumocele caused by a maxillary sinus mucocele.

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.

Management of paranasal sinus osteomas: A comprehensive narrative review of the literature and an up-to-date grading system.

Background: Surgical excision represents the unequivocal treatment modality for symptomatic paranasal sinus osteomas. However, the optimal surgical approach and the extent of the surgery, as well as the management stance in the case of an asymptomatic tumor, remain controversial.

Methods: The MeSH terms 'Osteoma', 'Nasal Cavity', and 'Paranasal Sinuses' were used to retrieve articles concerning the management of paranasal sinus osteomas that were published in the last 30 years, the vast majority of which comprised case reports of one or two cases.

Symptomatic retropharyngeal space lipoma. A patient with Madelung disease.

Background: Retropharyngeal space lipomas (RSL) are rare benign tumors of the head and neck region. They can, sporadically, occur as part of syndromic lipomatosis, such as Madelung disease. Symptoms are caused due to increasing pressure on surrounding structures.
