Objective: This retrospective study aimed to establish a robust rating system for assessing post-operative outcomes in congenital aural atresia patients undergoing auricular reconstruction. The newly introduced EAR scale, a weighted grading system, not only considers anatomical landmarks but also factors such as ear alignment. In addition, the outer-ear cartilage scale and the visual analogue scale (VAS) were introduced.

Background: The prelacrimal window approach (PLWA) is a minimally invasive surgical technique that has been proposed as an alternative to the traditional approaches to access the maxillary sinus.

Methodology: A systematic review with meta-analysis was performed following PRISMA guidelines and identified 368 articles for initial review of which 14 (610 participants) met the criteria for meta-analysis. Four databases, including PubMed, Google Scholar, Web of Science and Scopus, were searched to identify relevant articles.

Pyriform turbinoplasty (PT) is a surgical option for the management of turbinate hypertrophy. The philosophy and goal of the procedure are to improve the symptoms of a restricted airway while preserving function. We report a case of surgical management of inferior turbinate (IT) hypertrophy with PT and lateral nasal wall lateralization (LNWL).

Introduction Olfactory dysfunction (OD) is often a devaluated sensorial affection. The objective evaluation of this dysfunction doesn't evaluate its compromise in patients' daily life. Therefore, the use of a Portuguese-validated tool is of uttermost importance to objectively scale the pathology presented by these patients.

Objective: To assess hearing rehabilitation in patients with congenital aural atresia using an active middle-ear implant (Vibrant Soundbridge).

Methods: Of a cohort of 70 microtia and atresia patients, 10 underwent Vibrant Soundbridge implantation between 2008 and 2021. Two of the 10 patients had binaural implantation, resulting in 12 ears for analysis.

Objective: Our aim is to describe the location and course of the greater palatine canal (GPC) by analyzing its relationship with anatomical landmarks that can be used during endoscopic sinus surgery. This information might help prevent injury to the neurovascular bundle.

Methods: A retrospective evaluation of paranasal sinus CT scans of 100 consecutive random patients, 200 sides, was performed.

Background: The anterior superior alveolar nerve (ASAN) plays a major role in innervation of the lateral nasal wall. Its damage during nasal surgery can cause dental paraesthesia and numbness around the upper lip.

Methodology: Retrospective evaluation of the computed tomographic (CT) scans of 50 consecutive patients analysing 100 sides.

Objectives: An increasing proportion of patients who are candidates for endoscopic sinus surgery can be treated as an outpatient. A preoperative risk assessment is needed to evaluate eligibility for day surgery. This study analyses the effectiveness of a risk assessment scoring system which examines medical, procedure-related, and socioeconomic factors.

Background: The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I-Beam technique.

Objectives: The endoscopic technique in transnasal skull base surgery offers optimal visualization and free manipulation in the surgical field. However, it may cause approach-related sinonasal injury, influencing patients' quality of life (QOL). To minimize rhinological morbidity without restrictions in surgical manipulation and tumor resection, we introduced the unilateral transethmoidal-paraseptal approach.

Background: The distance between the anterior wall of the maxillary sinus and the nasolacrimal duct shows a large individual variation.

Methodology: To evaluate the feasibility of accessing the maxillary sinus through a prelacrimal window access (PLWA), a series of 100 paranasal CT scans from adult patients was analysed retrospectively. The distance between the anterior maxillary wall and the anterior border of the lacrimal duct (= prelacrimal window) were measured in 200 sides.

Background: Chronic rhinosinusitis (CRS) is a frequent disease with high social impact and multifactorial pathogenesis. Recently, single nucleotide polymorphisms within the TAS2R38 gene have been implicated as possible contributors to the complex gene-environment interactions in CRS. The purpose of this study was to confirm the proposed correlation between TAS2R38 genotype, CRS and related comorbidities.

Background: A new procedure, pyriform turbinoplasty, is described and nasal airflow is measured before and after this procedure in a virtual model.

Methodology: Pyriform turbinoplasty is the submucosal reduction of the bone of the frontal process of the maxilla and the lacrimal bone. It opens part of the lateral margin of the nasal valve area with minimal damage to nasal mucosa.
