[Microneural reconstruction after iatrogenic lesions of the lingual nerve and the inferior alveolar nerve. Critical evaluation].
As microneural repair techniques of the sensory mandibular branches enter the third decade of their clinical use, there are but a few long-term investigations into the value of these procedures in the treatment of iatrogenic injury to the lingual (LN), inferior alveolar (IAN) or mental (MN) nerve. To establish the efficacy of microneural repair in lesions of the LN, IAN or MN with loss of continuity, the outcome of sensory recovery was evaluated in a series of 92 patients (LN: direct coaptation n = 39, coaptation + sural nerve grafting n = 23; IAN: direct coaptation n = 11 coaptation + sural nerve grafting n = 10; MN: direct coaptation n = 11). The minimum duration of follow-up was 14 months postoperatively. ⋯ In the LN coaptation group low scores and improved taste perception were convincingly associated with short periods since injury (i.e. timing of repair). In conclusion, we feel there is sufficient justification to optimize the potential results of microneural repair by immediate (LN/MN) or early (IAN) reexposure of the injured site in order to clarify the precise nature of the underlying nerve damage and prevent delay, if patients present with complete loss of sensory function subsequent to dentoalveolar or oral surgery. However, clinical and electrophysiologic findings suggesting impairment or partial loss of sensory function are considered a contraindication to microneural intervention, in view of the limited prospects of sensory recovery after surgical repair.

[Postoperative pain after interventions in the area of the mouth-jaw-face].
In order to establish effective postoperative analgesia we studied the incidence and significance of pain following maxillofacial surgery. The trial included 102 patients undergoing one of six different surgical procedures. ⋯ Postoperative pain intensity was significantly correlated to operating time, the frequency of analgesic demand and the type of surgery (orthognathic surgery > TMJ surgery > osteosynthetic surgery > osteotomy of impacted third molars > tumor resection > removal of osteosynthetic materials). Patient's age, sex and ethnic origin did not significantly affect the severity of postoperative pain.
