In the canalicular syndromes, medical history and physical examination of the patient are crucial, and often the patient must be explored several times to diagnose the degree of injury and the potential irreversibility of the injury.
The correlation between clinical and neuropsychological tests is important, but must be assessed by the surgeon with clinical criteria.
The canalicular syndromes require surgery to relieve compression on the nerve and reduce the evolution of the nerve damage, improving the patient's symptoms and preventing nerve entrapment progression to irreversible damage that could cause sensory or motor permanent injuries.
The type of surgical indication and the timing varies with each lesion and the patient, so it is necessary to assess cases individually. It is also very important not differ in time, and unnecessarily, the surgical indication.
