3D printed ventilation tubes and their effect on biological models.

Background: Acute otitis media (AOM) causes inflammation and hearing loss. Ventilation tubes are key in treatment. 3D printing improves prostheses in otorhinolaryngology, offering precision and greater adaptability.

[Time of care and its impact in the evolution of laryngeal cancer].

Background: Laryngeal carcinoma is the 22nd most common cause of cancer in men worldwide and the second most common head and neck malignancy. The care of these patients is multidisciplinary. Factors such as tumor stage and initiation of treatment 60 days after diagnosis have been associated with worse survival.

[Clinical-pathological characterization of laryngeal cancer in the Mexican population].

Background: Cancer of the larynx occupies the first frequency site of cancer of the upper digestive tract and represents 42% of malignant neoplasms of the upper aero-digestive tract. It is a potentially curable entity if it is diagnosed in early stages.

Objective: Characterize the clinical pathological features of patients with laryngeal cancer, which can serve as a guide for diagnostic suspicion in primary and secondary care.

Olfactory Dysfunction in a Mexican Population Outside of COVID-19 Pandemic: Prevalence and Associated Factors (the OLFAMEX Study).

Purpose Of Review: To study the prevalence of olfactory loss and its associated factors in a Mexican population a cross-sectional analytical study based on a population interviewed about health, epidemiologic aspects, and sense of smell (tested with four scents: rose, banana, perfume, and gas) was conducted to evaluate olfactory detection, memory, and identification. Levels of sense of smell perception were determined when the participants detected, recognized, or identified all (normosmia), 1-3 (hyposmia), or none (anosmia) of the odorants. Associated factors of olfactory dysfunction were identified by multivariate analysis (odds ratio, 95%CI).

[Imploding antrum syndrome: three cases with different management approaches].

Background: Silent sinus or imploding antrum syndrome is a very rare condition, consisting of a usually asymptomatic spontaneous collapse of the sinus walls and floor of the orbit. It is associated with negative pressures, and when this occurs, it presents with manifestations such as enophthalmos, hypoglobus, and tilt flow orbital floor. As its incidence is very low, it is frequently missed as a diagnosis, and in fact there are currently fewer than 150 cases reported in the literature.

[Post-traumatic cholesteatoma with posterior fossa invasion].

Post-traumatic cholesteatomas are an extremely rare variety of secondary cholesteatomas. We present a case of a 51-year-old male with post-traumatic cholesteatoma with posterior fossa invasion of 30-year evolution that initially manifested as acute otomastoiditis and headache. Its physiopathology and clinical manifestations are discussed.
