[Hypoglossal nerve palsy after follicle puncture]. / Hypoglossusparese nach Follikelpunktion.

A 42-year-old female patient suffered an infranuclear hypoglossal nerve paresis with right-sided swelling and weakness of the tongue following a short duration mask anesthesia for a follicle puncture. This resulted in dysarthria and dysphagia persisting for more than 3 months. A return to work was initially impossible. Etiopathogenetically, a mechanical compression of the peripheral hypoglossal nerve by positioning or reclination during mask ventilation is discussed. Conclusion for clinical practice: In order to protect against lesions of the hypoglossal nerve, the pre-anaesthesiological examination should ask specifically about cervical problems as an indication of individual sensitivity to reclination. In such cases, special attention should be paid to careful patient positioning. Even shorter periods of reclination or compression of the soft tissues of the neck can result in lesions, therefore tolls such as a Wendl or Guedel tube should be used accordingly.
