Change in Levator Veli Palatini Muscle Activity in Relation to Swallowing Volume During the Transition from the Oral Phase to Pharyngeal Phase
Dysphagia, 2006Co-Authors: Takashi Tachimura, Kentaro Okuno, Maki Ojima, Kanji NoharaAbstract:The aim of this study was to examine whether the levator veli palatini (LVP) Muscle might be involved in the regulation of velopharyngeal function during the transition between the oral and pharyngeal phases during swallowing, and to examine whether LVP Muscle activity could be regulated in relation to the volume of swallowing. Eight normal adults participated in this study. Smoothed EMG signals of the LVP Muscle were collected. At the same time, Palatoglossus Muscle activity was also monitored. Each subject swallowed water at five different volumes: 12.5%, 25%, 50%, 100%, and 150 (or 200) % of the optimum volume for swallowing, which was individually determined for each subject. LVP Muscle activity was positively correlated with changes in swallowing volume. The LVP Muscle was involved in the regulation of swallowing during the transition from the oral to pharyngeal phases.

change in Palatoglossus Muscle activity in relation to swallowing volume during the transition from the oral phase to the pharyngeal phase
Dysphagia, 2005Co-Authors: Takashi Tachimura, Kanji Nohara, Maki Ojima, Takeshi WadaAbstract:The purpose of this study was to examine whether the Palatoglossus (PG) Muscle is involved in the regulation of function during the transition from the oral to the pharyngeal phase. Seven normal adults participated in the study. Smoothed electromyography (EMG) signals of the PG Muscle and levator veli palatini (LVP) Muscle were collected. Each subject swallowed water at five different volumes: 12.5%, 25%, 50%, 100%, and 150% (or 200%) of his/her optimum swallowing volume. PG Muscle waveform showed two patterns of activity: one of a single peak and the other of two peaks. There was no significant difference (p < 0.01) in the timing of emergence between the single peak and the second peak of the two-peak pattern. There were two patterns of PG Muscle activity in response to a change in swallowing volume, i.e., one was a pattern in which the activity was correlated to the change in swallowing volume, the other was a pattern in which the activity was not changed but almost at the maximum activity level, irrespective of swallowing volume. We conclude that the PG Muscle could be involved in the regulation of swallowing from the oral to the pharyngeal phase. The activity could be influenced by swallowing volume.

Anatomical-based classification for transoral lateral oropharyngectomy.
Oral oncology, 2019Co-Authors: Armando De Virgilio, Se-heon Kim, J. Scott Magnuson, Christopher Holsinger, Marc Remacle, Georges Lawson, Chen Chi Wang, Giuseppe Mercante, Luca Malvezzi, Oreste IoccaAbstract:Abstract Purpose The aim of the study is proposing a classification of different transoral lateral oropharyngectomy procedures in order to ensure better definitions of post-operative results. Methods The classification resulted from the consensus of the different authors and was based on anatomical-surgical principles. Results The classification comprises three types of lateral oropharyngectomy: type 1 is the resection of the palatine tonsil deep to the pharyngobasilar fascia; type 2 is performed by removing the entire palatine tonsil, the Palatoglossus Muscle, the palatopharyngeal Muscle and the superior constrictor Muscle; type 3 is performed by removing the entire palatine tonsil, the Palatoglossus Muscle, the palatopharyngeal Muscle, the superior constrictor Muscle, the buccopharyngeal fascia with extension to the pterygoid Muscle and parapharyngeal space fat content. Based on the extension of the dissection we can use the suffix A (soft palate), B (posterior pharyngeal wall), C (base of tongue) and D (retromolar trigone). Conclusion The proposed classification introduces a simple and easy to use categorization of transoral lateral oropharyngectomies into three classes. Resection extensions are easily described using suffixes.
