Detailed Radiomorphometric Analysis of the Surgical Corridor for the Suprageniculate Approach.

Background: The suprageniculate fossa (SGF) is located between the geniculate ganglion, the middle cranial fossa (MCF) and the anterior semicircular canal (ASCC). An endoscopic transcanal approach has been recently proposed to treat the different lesions in this area. The aim of the study is to describe the anatomical pathway of this approach by measuring the dimensions of its boundaries while checking their correlation with the pneumatization of the SGF area.

Radiological Classification and Management Algorithm of Petrous Apex Cholesterol Granuloma.

: Petrous apex cholesterol granulomas (PACGs) are benign inflammatory cystic lesions of the temporal bone. Usually, asymptomatic patients may develop symptoms as the lesions expand. The diagnosis is based on both CT and MRI scans and the management relies on "wait and scan" or surgery.

Endoscopic Temporalis Tendon Extension (ETTE).

Many techniques have been proposed to restore facial symmetry in facial nerve palsies. This study presents our surgical approach called Endoscopic Temporalis Tendon Extension (ETTE). After nasotracheal intubation, a 4 cm skin incision is made at the nasolabial fold.

Pericranial Flap-Based Multilayer Reconstruction of Endoscopic Transcribriform Craniectomy for Sinonasal Malignancies.

Objective: Diffusion of endoscopic techniques for the resection of ethmoid bone malignancies through a transcribriform approach (TA) has raised new challenges regarding reconstruction options to reduce post-operative complications. Although there is consensus on the advantages of vascularized flaps over free grafts for large defects, no standard protocol exists on reconstruction procedures. In addition, although the pedicled nasoseptal flap has been extensively discussed, few studies have been published on extranasal pedicled flaps.

Endoscopic transcanal surgery of pars tensa cholesteatoma: Preliminary results.

Introduction And Objectives: The aim of the present study is the assessment of exclusive endoscopic ear surgery for the management of primarily acquired pars tensa cholesteatoma, which is commonly linked to the failure of the Eustachian tube leading to the formation of retraction pockets.

Materials And Methods: Patients suffering from primarily acquired pars tensa cholesteatoma, who underwent primary surgery in our clinic, between 2014 and 2018 were included in this retrospective study. The disease was classified according to the EAONO/JOS system.

Artificial intelligence in head and neck cancer diagnosis.

Introduction: Artificial intelligence (AI) is currently being used to augment histopathological diagnostics in pathology. This systematic review aims to evaluate the evolution of these AI-based diagnostic techniques for diagnosing head and neck neoplasms.

Materials And Methods: Articles regarding the use of AI for head and neck pathology published from 1982 until March 2022 were evaluated based on a search strategy determined by a multidisciplinary team of pathologists and otolaryngologists.

Subcochlear canaliculus patterns in the pediatric and adult population: radiological findings and surgical implications.

Introduction: The pneumatization of the different regions of the temporal bone is strictly related to the age and the degree of development of the mastoid and the middle ear. Petrous apex pneumatization is the last step of the development of the petrous bone system. The subcochlear canaliculus is an anatomical cavity, originating in the space between the fustis and the finiculus, and connecting the round window area to the petrous apex.

Covid-19 and ENT practice: Our experience: ENT outpatient department, ward and operating room management during the SARS-CoV-2 pandemic.

Objectives: The current study aims at assessing the effectiveness of the guidelines set up by our clinic for the protection of patients and staff which enabled us to proceed with urgent and oncological surgery after the outbreak of the Covid-19 pandemic.

Material And Methods: Our ENT department devised specific equipment to be worn by the staff for personal protection when dealing with Covid-19 patients both in aerosol generating and non-generating procedures. Moreover, restrictive measures were enforced both for the outpatient department and for the ward where only urgent practices were carried out and visitors were not allowed, while non-urgent elective surgery was postponed.

Prevalence of PD-L1 expression in head and neck squamous precancerous lesions: a systematic review and meta-analysis.

Background: Studies concerning programmed death-ligand 1 (PD-L1) expression in precancerous lesions of head and neck (HN) region have shown variable results.

Methods: We systematically reviewed the published evidence on PD-L1 expression in HN precancerous lesions.

Results: Of 1058 original articles, 14 were included in systematic review and 9 in meta-analysis.

Role of endoscopy in lateral skull base approaches to the petrous apex.

Objective: The aim of this article is to study the role and advantages of combined microscopic/endoscopic procedures or exclusive endoscopic approaches in the treatment of petrous apex pathologies.

Methods: The study was designed as a retrospective case series analysis. We included patients affected by pathologies of the petrous apex, who underwent microscopic/endoscopic-assisted or exclusive endoscopic procedures.
