Background: A functional definition of ankyloglossia has been based on assessment of tongue mobility using the tongue range of motion ratio (TRMR) with the tongue tip extended towards the incisive papilla (TIP). Whereas this measurement has been helpful in assessing for variations in the mobility of the anterior one‐third of the tongue (tongue tip and apex), it may be insufficient to adequately assess the mobility of the posterior two‐thirds body of the tongue. A commonly used modification is to assess TRMR while the tongue is held in suction against the roof of the mouth in lingual‐palatal suction (LPS). Objective: This study aims to explore the utility and normative values of TRMR‐LPS as an adjunct to functional assessment of tongue mobility using TRMR‐TIP. Study Design: Cross‐sectional cohort study of 611 subjects (ages: 3‐83 years) from the general population. Methods: Measurements of tongue mobility using TRMR were performed with TIP and LPS functional movements. Objective TRMR measurements were compared with subjective self‐assessment of resting tongue position, ease or difficulty elevating the tongue tip to the palate, and ease or difficulty elevating the tongue body to the palate. Results: There was a statistically significant association between the objective measures of TRMR‐TIP and TRMR‐LPS and subjective reports of tongue mobility. LPS measurements were much more highly correlated with differences in elevating the posterior body of the tongue as compared to TIP measurements (R2 0.31 vs 0.05, P <.0001). Conclusions: This study validates the TRMR‐LPS as a useful functional metric for assessment of posterior tongue mobility. [ABSTRACT FROM AUTHOR]

Almost all surgical repair techniques for hypospadias include dissection of the glans penis, and covering the neo‐urethra with the glans tissue circumferentially. Surprisingly, the presence of the "septum glandis" in the ventral midline has been overlooked for decades. A careful examination of six patients with iatrogenic hypospadias (IH) revealed direct indications of the septum glandis. All patients were treated with long‐term urethral catheterisation in the paediatric intensive care unit due to neurologic and/or metabolic diseases. The glans was disrupted in all patients due to ventral midline compression of the urethral catheter, which resulted in a tear in the septum glandis. A remnant of the septum glandis was clearly observed in patients with an incomplete tear. Further injuries caused tear in the frenulum and corpus spongiosum, exposed the glanular urethra and made its vertical elliptical shape, the "fossa navicularis", visible. Intact contours of the separated glans wings were observed in all patients. The glans wings merge ventrally in the midline, but are separated by a fine connective tissue (septum glandis) in conjunction with the frenulum, which is involved in the formation of the ventral wall of the glanular urethra. IH provides further insight into the structural anatomy of the normal human glans and glanular urethra. [ABSTRACT FROM AUTHOR]

Objectives: To characterize associations between restricted tongue mobility and maxillofacial development.Setting and Sample Population: Cross-sectional cohort study of 302 consecutive subjects from an orthodontic practice.Material and Methods: Tongue mobility (measured with tongue range of motion ratio [TRMR] and Kotlow free tongue measurement) was correlated with measurements of the maxillofacial skeleton obtained from dental casts and cephalometric radiographs.Results: Tongue range of motion ratio and Kotlow measures of restricted tongue mobility were associated with (i) ratio of maxillary intercanine width to canine arch length, (ii) ratio of maxillary intermolar width to canine arch length and (iii) soft palate length. Restricted tongue mobility was not associated with hyoid bone position or Angle's skeletal classification.Conclusions: Restricted tongue mobility was associated with narrowing of the maxillary arch and elongation of the soft palate in this study. These findings suggest that variations in tongue mobility may affect maxillofacial development. [ABSTRACT FROM AUTHOR]

To explore the beliefs and practices of Australian surgeons regarding surgical intervention to release tongue-tie and to determine the main referral sources. In addition, we aimed to ascertain if there were differences in beliefs and practices according to surgical specialty.Four hundred surgeons in three different surgical specialties were surveyed via questionnaire. Multiple choice response questions and open ended questions were used to explore beliefs and practices surrounding tongue-tie assessment, management and follow up. The questionnaires were distributed by email (where available), followed by fax and mail.A response rate of 80.8% (n = 323) was obtained. Of these, 236 (73%) reported they practised surgery to release tongue-tie; 46% were oral and maxillofacial surgeons, 37% were plastic surgeons and 17% were paediatric general surgeons. Indications for surgical management and follow up varied according to surgical specialty. There was no clear consensus regarding clinical indicators for surgery or functional outcomes following surgery.It appears that until a prospective study designed to address some of the controversial issues outlined is undertaken, we will remain ignorant about the need for surgery to release tongue-tie in children.

An investigation of disparate gingival heights of the mandibular central incisor region in 93 children aged from 6 to 12 years was undertaken. Unaffected paired teeth demonstrated an age-associated increase in clinical crown length, similar to previous reports, suggesting a gradual remodelling of soft tissues. Affected teeth displayed a rapid increase in clinical crown length suggesting that by age 10 years true recession had occurred. Significant associations with gingival inflammation (at the 0.1 % level), and with anterior crowding (at the 0.2% level), occurred. Frenal involvement did not influence the position of the gingival margin. [ABSTRACT FROM AUTHOR]
