Tongue01:01

Tongue

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...
The Tongue and Taste Buds00:49

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Deglutition01:25

Deglutition

Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...

Area of Science:

  • Oral surgery
  • Reconstructive surgery
  • Head and neck oncology

Background:

  • Oral cavity defects often require reconstruction after ablative surgery.
  • Choosing the right reconstructive method is crucial for functional outcomes.
  • Dorsal tongue flaps offer a potential solution for intraoral defects.

Purpose of the Study:

  • To evaluate the efficacy of single-staged, posteriorly based dorsal tongue flaps.
  • To assess flap viability, functional results, and donor site morbidity.
  • To determine the usefulness of this technique in oral cavity reconstruction.

Main Methods:

  • Prospective data collection from July 2006 to November 2010.
  • Analysis of 27 patients undergoing dorsal tongue flap reconstruction.
  • Inclusion of patients with defects ranging from 3.5-5 cm, including those with marginal mandibulectomy or mucoperiosteal stripping.

Main Results:

  • No partial or total flap loss observed in the study cohort.
  • Two patients experienced minor salivary leaks, managed conservatively.
  • All patients achieved adequate mouth opening, speech, and swallowing post-surgery.

Conclusions:

  • The dorsal tongue flap is a straightforward and dependable flap for intraoral reconstruction.
  • This technique yields favorable functional results.
  • Donor site morbidity associated with dorsal tongue flaps is minimal.
