An Account of Roman Surgical Treatments for Ozena: Historical Review

The Laryngoscope, EarlyView.
This historical study investigates ancient Roman surgical techniques for treating ozena as described by Celsus, with a focus on its historical and etymological context. Independent translation and archaeological evidence contextualize two ancient procedures: closed nasal cauterization using a heated probe and an open approach involving dissection and ...

Numerical and Machine Learning Analysis of the Parameters Affecting the Regionally Delivered Nasal Dose of Nano- and Micro-Sized Aerosolized Drugs

Pharmaceuticals, 2023
The nasal epithelium is an important target for drug delivery to the nose and secondary organs such as the brain via the olfactory bulb. For both topical and brain delivery, the targeting of specific nasal regions such as the olfactory epithelium (brain)

Nasal irrigation delivery in three post-FESS models from a squeeze-bottle using CFD [PDF]

arXiv, 2022
Purpose: Nasal saline irrigation is highly recommended in patients following functional endoscopic sinus surgery (FESS) to aid the postoperative recovery. Post-FESS patients have significantly altered anatomy leading to markedly different flow dynamics from those found in pre-op or non-diseased airways, resulting in unknown flow dynamics. Methods: This

Impact of Nasal Pathology on Efficacy of Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea

The Laryngoscope, EarlyView.
Hypoglossal nerve stimulation (HNS) is a surgical treatment for patients with obstructive sleep apnea (OSA) who cannot tolerate continuous positive airway pressure. Comorbid nasal pathology, such as septal deviations, turbinate hypertrophy, polyps, vestibular stenosis, and masses, is frequently seen and has been shown to decrease quality of life in ...

On computational fluid dynamics models for sinonasal drug transport: relevance of nozzle subtraction and nasal vestibular dilation [PDF]

arXiv, 2017
Generating anatomically realistic three-dimensional (3D) models of the human sinonasal cavity for numerical investigations of sprayed drug transport presents a host of methodological ambiguities. For example, subject-specific radiographic images used for 3D reconstructions typically exclude spray bottles.

In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications

Macromolecular Materials and Engineering, EarlyView.
Drug delivery through the nasal route offers many advantages, but is hampered by a number of challenges, such as the short drug retention time caused by mucociliary clearance. In situ forming gels, which undergo a sol‐to‐gel transition with specific triggers at the site of action, present real opportunities in this field.

Recommendation for Standardized Exam for Nasal Obstruction. [PDF]

Laryngoscope Investig Otolaryngol
ABSTRACT Introduction Nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise are among the most common etiologies of NAO seen by facial plastic surgeons and otolaryngologists. Discussion While both validated and non‐validated scales and grading systems exist, they are inconsistently used.

Giant follicular cysts extended in pterygo-maxillary fossa, antro-naso-ethmoidal and orbital space associated to exophtalmos and diplopia in young patients

Oral and Maxillofacial Surgery Cases, 2018
Follicular cysts develop from the enamel epithelium of an un-erupted tooth. Two cases of extremely large and extended follicular cysts related to the upper impacted third molars in young patients and treatments are described.

Trilayer Temporalis Fascia Interposition Graft for Nasal Septal Perforation Repair: A Continued Experience

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective The repair of nasal septal perforation (NSP) is complex, with a variety of described techniques and reported outcomes. At our institution, we commonly perform NSP repair using a trilayer graft of thin polydioxanone (PDS) plate wrapped on both sides with temporalis fascia without intranasal flaps.

Myxofibrosarcoma of the Nasal Vestibule: A Case Report and Literature Review

B-ENT
Myxofibrosarcoma is a malignant tumor originating from fibroblast or myofibroblast, with an incidence of about 5% in soft tissue sarcomas. However, myxofibrosarcomas that originate from and are restricted to the nasal vestibule are rarely seen in the ...
