______About the dataset______This dataset contains time-series recordings of facial movements captured using a Kinect stereo-vision camera (Microsoft, USA) in patients after head and neck surgery who developed facial paresis. The purpose of the dataset is to support objective assessment of rehabilitation progress using a simplified House–Brackmann (HB) scale. Each sample consists of complex 3D trajectories of facial landmarks measured over time.

______Sample preparation______Patients performed standardized facial tasks while being recorded with the Kinect system (Microsoft, USA). Each measurement includes sequences of 3D landmark positions. To balance class frequencies, HB4 samples were merged into HB3 and HB5 samples into HB6, resulting in four final HB categories for analysis.

______Methods of data collection______Data were collected using a Kinect stereo-vision camera (Microsoft, USA), capturing 3D spatial coordinates of facial landmarks over time. The dataset contains 122 measurements from 93 study participants who signed an informed consent form. Each measurement includes multiple time curves representing the movement of facial points.

______Methods of data processing______Processing involves extracting time-dependent trajectories of facial landmarks. Several supervised learning methods were tested for HB scale classification:Neural networks.- --------------------------------------------------------------------FILE TYPES & FORMATS, SW TO OPEN AND DIMENSIONS & UNITS--------------------------------------------------------------------File format: The dataset is provided as a single exported data file derived from our internal database (CSV).
