Summary
Orthognathic surgery can alter taste sensation, particularly bitter and sweet flavors, due to potential nerve damage. Patients may experience changes in taste perception following procedures like Le Fort I osteotomy and sagittal split ramus osteotomy.
Area of Science:
- Oral and Maxillofacial Surgery
- Neurosensory Science
- Surgical Outcomes Research
Background:
- Orthognathic surgery aims to correct jaw and facial deformities.
- Potential impacts on sensory functions, including taste, are a concern post-surgery.
Purpose of the Study:
- To investigate the effects of orthognathic surgery on taste sensation.
- To evaluate taste perception changes following Le Fort I osteotomy, sagittal split ramus osteotomy, and bimaxillary surgery.
Main Methods:
- Thirty-five patients underwent taste tests (localized and whole-mouth) preoperatively and at 1, 3, and 6 months postoperatively.
- Patients identified taste qualities and rated intensities on the tongue and palate.
- Taste recognition thresholds and intensity scores were analyzed based on surgical groups and follow-up times.
Main Results:
- Le Fort I osteotomy (LFIO) patients showed decreased quinine HCl (bitter) recognition thresholds post-surgery.
- Sagittal split ramus osteotomy (SSRO) patients reported decreased sucrose (sweet) taste intensity on the tongue.
- LFIO patients experienced increased quinine HCl taste intensity on the anterior tongue.
Conclusions:
- Orthognathic surgery can affect taste perception due to potential chemosensory nerve alterations.
- While many taste alterations are non-significant, specific changes in bitter and sweet taste perception occur.
- Maxillofacial surgeons and patients should be aware of potential taste changes after orthognathic procedures.

01:20Taste Buds and Receptors
1.9K
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,...

01:24The Physiology of Taste
3.9K
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...

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

01:03Olfactory Receptors: Location and Structure
9.2K
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...

01:14Conditioned Taste Aversion
135
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...
