The function of the olfactory and gustatory receptors is to monitor the air breathed and the food intake. Although humans are less dependent on chemosensory input than other mammals, olfactory and gustatory function still plays a critical role in health and behavior. The olfactory and gustatory system have historically received less attention than other special senses, perhaps due to challenges related to its study in humans. In this article, we review the olfactory and gustatory epithelial anatomy, epithelial recognition of stimulants and rela...

The dysfunction to smell and taste, is estimated to afflict 3–20% of the population. Risk of chemosensory dysfunction increases with old age and may also result from chronic sinonasal diseases, severe head trauma, and upper respiratory infections, or neurodegenerative diseases. These disorders impair the ability to sense warning odors in foods and the environment, as well as hinder the quality of life related to social interactions, eating, and feelings of wellbeing. The primary concern of both patients and doctors with chemosensory dysfuncti...

The olfactory and gustatory function tests are diagnostic tools to identify disorders of smell and taste related disorders which impair risk detection and quality of life in daily life. Also the tests are involved in the early detection of neurodegenerative diseases and medico-legal problems responsible for compensation. There is a subjective test that evaluates an examinee’s subjective response to stimuli and an objective test that evaluates the examinee’s physical response to stimuli. The subjective olfactory and gustatory function tests ...

Bilateral facial palsy is a rare disease which accounts for 0.3~2.0% of the facial palsy cases. Bilateral facial palsy is defined as simultaneous onset of facial palsy which means the involvement of the opposite side within 4 weeks of the onset of the first side. The underlying etiology of bilateral facial palsy can be extensive - neurological, infectious, neoplastic, traumatic, metabolic or degenerative disorders are included. Although it can be a diagnostic challenge, rapid diagnosis is essential for proper treatment. Hearin, we report our ex...

Although chronic otitis -media (COM) with cochlear fistula is uncommon situation in cochlear implantation (CI), there are still debate on the choice between sequential and simultaneous COM management and CI. To decide one stage or staged operation could be one of an important consideration for operation preparation. We report two deaf patients with a cochlear fistula who simultaneously underwent subtotal petrosectomy, fistula repair, and CI. (J Clinical Otolaryngol 2020;31:196-199)

Osteoma often develops in the skull and facial bones, most frequently in the paranasal sinuses, but rarely develops in the temporal bone. Temporal osteoma is most commonly seen in the external auditory meatus, followed by in the mastoid process. Although temporal osteoma can vary in size, it does not exceed 3 cm in most cases. In this case, a 64-year-old woman presented with a left-sided skull mass located behind the auricle that had grown gradually in size over the past 40 years. The mass was a giant osteoma exceeding 3 cm in diameter (maximum...

Sinus mucocele is epithelial lined benign cystic lesion usually due to obstruction of the sinus ostia. It is commonly seen in frontal and ethmoidal sinus, although rarely, in sphenoid sinus. Anterior clinoid process is bony process on the superolateral aspect of the sphenoid sinus and its pneumatization is observed approximately 9.5% in sphenoid sinus. An anterior clinoid process mucoceles account for merely 1% of paranasal sinus mucoceles and can lead to optic neuropathy, or even dysfunction of third, fourth, sixth cranial nerves due to its pr...

Flap reconstruction of nasal tip defect after wide excision is challenging. Forehead flap is usually utilized because of relatively high success rate and acceptable cosmetic results. But donor site problem and unsatisfied aesthetic outcome could be an issue. Especially, it becomes complex and difficult when columella and philtrum reconstruction is necessary. Bilateral nasolabial rotation flap could be an alternative option for overcoming forehead flap disadvantages. The authors introduce a case of bilateral nasolabial rotation flap reconstructi...
