简要总结
Orthognathic surgery refers to jaw operations that can be performed on the upper jaws (Le Fort I osteotomy) and lower jaws (Sagittal Split Ramus osteotomy). In orthognathic surgery practice, taste perception could be affected by potential damage to peripheral nerves that conduct chemosensory information regarding gustation from the palate and tongue. This study aimed to evaluate the changes in the sense of taste after Le Fort I osteotomy, Sagittal Split Ramus osteotomy, and bimaxillary surgery.
详细描述
The subjects were orthognathic surgery patients with facial skeletal deformities who applied to the Department of Oral and Maxillofacial Surgery. Thirty-five patients, aged 17-42 years, gustatory functions were evaluated by administering localized taste tests and whole mouth taste tests preoperatively and at postoperative 1st, 3rd, and 6th months. In the tests, solutions containing sucrose for a sweet taste, sodium chloride for a salty taste, citric acid for a sour taste, and quinine hydrochloride for a bitter taste were used. Patients were compared between the operation group they were in and between operation groups.

结局指标
主要结局
Taste recognition threshold
时间窗: Six months
The solutions were administered in increasing concentrations, starting from the lowest concentration up to the highest concentration until the patient perceived any taste. The lowest concentration at which the patient correctly perceived the administered taste was defined as the "taste recognition threshold. Taste recognition threshold is the primer outcome for whole-mouth taste tests.
Taste intensity rating
时间窗: Six months
The patients were instructed to focus on the perceived taste without closing their mouths and asked to identify the taste and rate the intensity of the taste using a scale ranging between 0 'no taste' and 9 'strongest taste', after each administration. Taste intensity rating is the primer outcome for localized taste tests.
