Before surgery all important landmarks and reference points must be identified and marked. Important landmarks are the hairline, frown lines, location of the supratrochlear vessels, outline of the defect, nasal and lip subunits. [1] Then templates are made using the intact side of the nose to make a precise symmetric reconstruction of the nose.
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
– Open rhinoplasty: To narrow the tip of a too-wide nose, the surgeon first determines the cause of the excess nasal width. The suture being emplaced will narrow the tip of the nose. The red delineation indicates the edge of the nose-tip cartilage, which is narrowed when the surgeon tightens the folded cartilage apex.
It must have enough structure to support restoration. Filling the root canals of the tooth from the crown (orthograde root canal therapy) should be the first treatment option to resolve inflammation caused by the tooth. Periradicular surgery is only considered if the inflammation persists after conventional root canal treatment.
Root canal treatment should be performed on the tooth if it is determined that previous therapy was unsuccessful. Removal of the necrotic pulp and the inflamed tissue as well as proper sealing of the canals and an appropriately fitting crown will allow the tooth to heal under uninfected conditions.
Pain can also be referred to the upper teeth and be mistaken for toothache. [4] Another symptom is the movement of fluid from the mouth through the communication and into the maxillary sinus, as the maxillary sinus is connected to the nose and therefore fluid can come out of the nostrils when drinking.

Temporary numbness of the front upper teeth after surgery is common. [5] Sometimes the numbness extends to the upper jaw and the tip of the nose. This almost always resolves within several months. The nasal tissues should mostly stabilize within 3-6 months post-surgery, although shifting is still possible for up to and over a year afterwards. [6]
