After a chin correction, the sensation in the lower lip and chin is always disturbed. If the mental nerve (which comes out of the jawbone just behind the chin and then runs into the lower lip and the skin of the chin) was not torn during the operation, the sensitivity will certainly return. However, when and to what extent is impossible to predict. Usually, recovery takes several weeks to several months, but it can even take up to two years. It is normal that the sensitivity of the lower lip and chin does not fully recover. If the mental nerve is torn (in the hands of Dr. Bert Oelbrandt less than 1%), it can be sutured. Of course, the prognosis will then be worse. However, damage to the mental nerve will not be visible to the outside world, as it is a 100% sensory nerve. It does not contain any motor branches, so the function of each muscle remains intact.
