Summary

This lecture, part of a postgraduate teaching program, covers the radiological anatomy of the oral cavity, focusing on the tongue and buccal mucosa. The speaker, Dr. Nivedita Chakraborty, an associate professor in radiodiagnosis, begins by defining the boundaries of the oral cavity, including the lips, hard and soft palate, and the junction of the anterior two-thirds and posterior one-third of the tongue. She then details the intrinsic and extrinsic muscles of the tongue, using MRI images to illustrate their appearance. The root of the tongue, including the lingual septum and genioglossus muscle, is discussed, along with the floor of the mouth and the mylohyoid sling. The lecture also covers the vestibule, buccal mucosa, and the buccomasseteric space, highlighting the pterygomandibular raphe and its clinical significance. The infratemporal fossa and masticator space are explained, with emphasis on distinguishing low and high ITF levels. The mandible’s anatomy, including the lingual and buccal plates and the mandibular canal, is described. The pterygopalatine fossa and its connections are also reviewed. The session concludes with a Q&A segment where the speaker addresses questions on imaging modality selection (MRI vs. CT) for various oral cavity subsites, perineural spread, skin involvement, tumor volume measurement, and the significance of peritumoral edema.

Critical Evaluation

Value of the Information & Strength of the Argument

The lecture provides valuable information for radiologists and clinicians, offering a systematic review of oral cavity anatomy with practical imaging correlations. The speaker’s expertise is evident in her detailed descriptions and her ability to answer clinical questions with reasoned explanations. The argumentation is solid, based on anatomical principles and clinical experience, though it lacks formal citations. The Q&A session enhances the value by addressing common clinical dilemmas, such as when to use MRI versus CT and how to interpret indirect signs of perineural spread.

Scientific Rigor, Source Quality, Title Accuracy

The lecture demonstrates scientific rigor in its anatomical accuracy and logical structure. However, it does not cite specific sources or references, which limits its verifiability. The title accurately reflects the content, and the lecture stays focused on the radiological anatomy of the oral cavity. The speaker’s expertise and the interactive Q&A add credibility, but the lack of formal citations is a minor weakness.
