Summary
Taste dysfunction is a common complication after vestibular schwannoma surgery, affecting nearly half of patients. Preoperative taste issues were noted in 40.8%, and postoperative disturbances occurred in 45.8% of cases.
Area of Science:
- Neurosurgery
- Otolaryngology
- Neuroscience
Background:
- Vestibular schwannomas (VS) can present with poorly documented gustatory dysfunction.
- Taste disturbances are an underrecognized clinical manifestation associated with VS.
Purpose of the Study:
- To investigate the incidence and characteristics of taste dysfunction in patients undergoing vestibular schwannoma surgery.
- To assess the impact of VS surgery on taste sensation.
Main Methods:
- A retrospective study included 142 patients with vestibular schwannoma operated between 1997 and 2005 with at least six-month follow-up.
- Patients underwent preoperative and postoperative taste sensation testing using four standard taste modalities.
- Altered or abnormal taste perceptions were systematically recorded.
Main Results:
- Preoperative decreased taste sensation was observed in 40.8% of patients.
- Postoperative taste disturbances occurred in 45.8% of patients, even with facial nerve preservation (42.3%).
- A small percentage (6.9%) of patients reported improved taste sensation post-surgery.
Conclusions:
- Taste dysfunction is a frequent outcome following vestibular schwannoma surgery.
- Preoperative patient counseling regarding potential taste disturbances is essential.
- Incorporating taste dysfunction into facial nerve functional grading systems is recommended for comprehensive outcome assessment.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:15Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
01:24The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
01:16Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
