The anatomical knowledge of structures such as vessels, nerves and the skull base is essential for endonasal surgeries to be performed safely. The anterior ethmoidal artery is an important anatomical landmark that has three segments: intraorbital, intranasal and intracranial. Inadvertent injuries to this structure may evolve to blindness and cerebrospinal fluid fistula. This study aims to provide the mean distance between the anterior ethmoidal artery and the middle turbinate axilla, through...

Introduction: Epistaxis is considered one of the main emergencies within the specialty of otorhinolaryngology. It is estimated that 60% of the population has gone through or will go through at least 1 episode of epistaxis during their lifetime. Only 6%, however, require medical intervention. Still, in some cases the severity is such that patients require emergency intervention at risk of death. Objectives: Evaluate the main risk factors and identify the epidemiological profile - age, sex,...

Introduction: Edema and ecchymosis are the two most common complications that occur in the immediate postoperative period after rhinoplasties. Arnica montana is a homeopathic medicine used in wound healing and to improve edema and ecchymosis. The purpose of this study is to compare the benefit of Arnica montana used topically with the oral route after rhinoplasty. Methods: In this clinical trial, study subjects were divided into three groups. The first group received topical Arnica montana...

The nasal conchae are able to increase the volume of the nasal mucosa and regulate the respiratory flow. In embryology, while the inferior turbinate is a separate structure, the middle, superior, and supreme turbinates originate from the uppermost portion of the septum. In surgical access to the posterior sinuses, especially the sphenoid sinus, and in the access to the skull base, the identification of the superior turbinate is very important, as this structure is connected superiorly to the...

Chronic rhinosinusitis is a condition of nasal inflammation that requires multifactorial treatment, including surgery, with indication of nasal irrigation to reduce nasal symptoms. Xylitol can be associated with nasal irrigation due to its therapeutic effect. Our study aims to assess the relationship between the effects of nasal irrigation with saline solution compared to xylitol through clinical questionnaires (visual analogue scale, NOSE and SNOT-22). Fifty-two patients, divided into two...

Allergic rhinitis (AR) is a worldwide public health problem as it affects the quality of life of patients. There is great concern with its correct diagnosis, as well as with the development of suitable instruments for its monitoring. The use of apps on smartphones and tablets has had a profound impact on medicine. A natural trend of modern medicine is to empower patients, while encouraging and educating them so that they are able to better understand and treat their condition. This is an...

Cataract is the name given to any opacity of the crystalline lens, and is the leading cause of treatable blindness in developing countries. Its main cause is related to aging. This study intends to provide a survey of patients’ profile data regarding age, gender, operated eye, onset of symptoms, level of visual impairment and risk factors of patients who underwent cataract surgery at the Hospital Paranaense de Otorrinolaringologia – IPO between September and October 2022. A descriptive...

Nasal obstruction due to internal nasal valve collapse is relatively common. This paper systematically reviews the existing literature that supports the efficiency and value of using the traditional spreader graft and butterfly graft techniques in functional rhinoplasty for the correction of internal nasal valve incompetence.

Among the emergencies otorhinolaryngologists most commonly see in the emergency room are nasal fractures, often regarded of minor importance, though with the chance of significant cosmetic and functional damage. This study aimed to outline a profile of the patients seen and treated in a reference service in the city of Curitiba, state of Paraná. A retrospective study related to the pathology was performed with the investigation of variables such as sex, age, semiology, etiology, diagnostic...

This article demonstrates the evolution of knowledge transmission through augmented reality (AR) for a safer procedure for otoplasty surgery. The fixation of the remaining concha in the mastoid region is a fundamental step, as it allows solving the bad positioning of the auricular pavilion, providing its retropositioning, simultaneously, with the superior rotation.
