  • Dental arch relationship: describes the way the upper teeth are positioned in relation to the lower teeth
  • GOSLON index: A method of assessment of dental arch relationships
  • Grommet: a tube which is placed in the ear drum to allow air into the middle ear in the treatment of secretory otitis media (glue ear)
  • Gingio-periosteoplasty: Moving potentially bone-forming tissue over the alveolar gap at the time of primary lip repair.
  • Palatal Fistula: a hole between the mouth and nose arising following closure of a cleft palate.
  • Hypernasality: excessive nasal tone caused by inadequate closure of the soft palate
  • Maxilliary retrusion: the top jaw front teeth lie behind the lower jaw teeth with the mouth closed.
  • Mucosa : The wet lining of the nose and mouth
  • Nasendoscopy: investigation with an endoscope passed through a nostril, used for assessing palate function
  • Naso-gastric intubation: the insertion of a plastic feeding tube (nasogastric tube or NG tube) through the nose down into the stomach.
  • Naso-labial appearance: profile and frontal appearance of the nose and upper lip
  • Neonatal appliance: oral plate sometimes used to help feeding and to guide the growth of the gum segments

  • Submucous cleft palate: occurs when the mucosa of the palate is intact but the palatal muscles are not intact.
  • T tube: A long lasting type of grommet
  • Velophryngeal insufficiency (VPI): failure of the soft palate to close against the pharyngeal wall, causing hypernasality which may be corrected by velopharyngeal surgery
  • Videofluoroscopy: A video x-ray used to assess soft palate function during speech and swallowing
