The relationship (position/angulation) of maxillary transmigrant canine with median palatine suture and the distance travelled in contralateral arch past midline suture by transmigrated canine along its long axis was also evaluated.
Only the tip of crown till approximate half of crown positioned in the median palatine suture was observed in 60% cases of transmigrant maxillary canines (Figure 7).
In three cases (60%), tip of crown till less than halfway of crown of transmigrant maxillary canines was positioned in the median palatine suture whereas in 40% of the cases more than half of crown (till cementoenamel junction) of transmigrant maxillary canine was observed to cross the median palatine barrier.
Shapira and Kuftinec had suggested that the migrating maxillary canine probably tunnels through the bone as median palatine suture typically remains intact radiographically in all previously documented cases .
The panoramic radiographs must be used for evaluation of impacted canines and the usage of CBCT should be implemented in advanced treatment planning as it would provide more precise information about the localisation of transmigrated canine and its relationship to surrounding teeth and median palatine suture.
Considering that in case of submucous resections of nasal septum the specified median palatine suture and the nasal crest are bared from the side of nasal cavity, in our opinion it would be more expedient to make crestotomy and suturotomy (a prototype of compactosteotomy) in endonasal way at the time of septectomy.
to ground the possibility of new method of operative intervention--septum surgery (septectomy) with cresto- and suturotomy of the nasal crest and median palatine suture in case of NSC together with DMA.
Septum surgery technique with cresto- and suturotomy of nasal crest and median palatine suture to avoid dento-maxillary anomaly relapses after orthodontic interventions
On the front end of a median palatine suture, behind alveolus of incisors, is located the incisory aperture, foramen incisivum (the nerves with the same name and vessels pass through it), conducting into incisory channel, canalis incisivus.
The palatine portion was "U" shaped with a straight and smooth median palatine suture
INC--incisulare, the "place of direct contact between the median palatine suture and the posterior margin of incisive foramen" (Skrzat et al.
