Sphenomaxillary Plate: Landmine or Landmark?

Objectives: Sphenomaxillary plate (SMP) is an inconstant bony septum separating the maxillary and sphenoid sinuses. Neglecting the SMP during endoscopic sinus surgery may lead to mistaking the sphenoid sinus for the posterior ethmoid cell with potentially dangerous consequences. However, its proper identification may allow planned sphenoidotomy through the posterior wall of the maxillary sinus or to enlarge transnasal or transethmoidal sphenoidotomy.

Solvent-free temperature-facilitated direct extrusion 3D printing for pharmaceuticals.

In an era moving towards digital health, 3D printing has successfully proven its applicability in providing personalised medicine through a technology-based approach. Among the different 3D printing techniques, direct extrusion 3D printing has been demonstrated as a promising approach for on demand manufacturing of solid dosage forms. However, it usually requires the use of elevated temperatures and/or the incorporation of an evaporable solvent (usually water).

Endoscopic combined middle and inferior meatal antrostomies approach in treatment of maxillary sinus inverting papilloma.

Introduction: Endoscopic medial maxillectomy is currently the most commonly used endoscopic approach to the maxillary sinus inverting papilloma. The possible complications of this procedure include epiphora, crusting and empty nose syndrome. Another method, a prelacrimal recess approach, enables preservation of the nasolacrimal duct and inferior nasal turbinate, but offers limited possibility of postoperative endoscopic follow-up.

Temperature and solvent facilitated extrusion based 3D printing for pharmaceuticals.

On demand manufacturing of patient-specific oral doses provides significant advantages to patients and healthcare staff. Several 3D printing (3DP) technologies have been proposed as a potential digital alternative to conventional manufacturing of oral tablets. For an additive manufacturing approach to be successful for on-demand preparation, a facile process with minimal preparation steps and training requirements is needed.

Osteoma involving the olfactory groove: evaluation of the risk of a CSF leak during endoscopic surgery.

Purpose: The olfactory groove (OG) is a common site of iatrogenic cerebrospinal fluid (CSF) leak during endoscopic sinus surgery. We aimed to evaluate the prevalence of CSF leak during endoscopic removal of osteomas involving the OG and identify CT findings indicating increased risk of this complication.

Methods: A retrospective review was conducted of patients operated on for frontoethmoidal osteoma from 11 years in a single institution.

Three-dimensional computed tomography analysis of frontoethmoidal cells: A critical evaluation of the International Frontal Sinus Anatomy Classification (IFAC).

Objectives: Two major classifications of frontoethmoidal cells, Lee and Kuhn and the IFAC (International Frontal Sinus Anatomy Classification), distinguish anterior, posterior and medial cells. The European anatomical position paper includes also lateral cells. According to the IFAC, anterior cells push the frontal sinus drainage pathway (FSDP) medially, posteriorly or posteromedially.

Lateral frontoethmoidal cell obstructing frontal sinus drainage pathway - report of six cases.

Unlabelled: The European Anatomical Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses distinguishes anterior, posterior, medial and lateral frontoethmoidal cells. The lateral cells have not been characterized yet. Other classifications (Lee and Kuhn, International Frontal Sinus Anatomy Classification) neglect them.

Hidden unilateral aplasia of the frontal sinus: a radioanatomic study.

Background: Hidden unilateral frontal sinus aplasia is the absence of 1 frontal sinus with increased pneumatization of contralateral sinus toward the aplastic side. It may give the false impression of the presence of 2 separate frontal sinuses, creating potential for complications during the surgery. The aim of this study was to evaluate the prevalence and morphology of this anatomical variation using multiplanar reconstruction of computed tomography (CT) results.

Asymmetry of the anterior skull base at the level of frontal ostium, a radioanatomical study.

Background: Radioanatomical studies have shown that the ethmoid roof is asymmetric in 10 to 40% of individuals. The right ethmoid roof has been found on average to be lower compared to the left. The aim of this study was to extend existing results by assessing asymmetry between the right and left anterior skull base at the level of the frontal ostium.

Endoscopic transnasal management of sinonasal malignancies - our initial experience.

Introduction: Malignant tumors of the paranasal sinuses are traditionally managed through external approaches. Advances in endoscopic transnasal surgery have allowed for the endoscopic treatment of some of these tumors.

Aim: To present the results of treatment of a series of patients with paranasal sinus malignancies treated with an endoscopic approach at a single institution.

[Usefulness of 18F-FDG PET/CT examination in the diagnosis of head and neck cancer--preliminary results].

Objectives: The aim of the study was to determine the usefulness of 18-FFDG PET/CT in oncological diagnostics in laryngology.

Material And Methods: 45 PET/CT examinations were performed in 41 patients diagnosed with head and neck cancer in Department of Otolaryngology and Nuclear Medicine Department WUM from 2008 to 2011. In 3 patients PET/CT study was conducted several times.
