A Novel Technique for Protection of Facial Nerve during Parotidectomy

ABSTRACT

Identification and protection of Facial Nerve is of prime importance during surgery of parotid glands. Several techniques are available in literature to identify and preserve FN. We present here a case series with dissection of FN in a novel technique during parotidectomy which has significantly lowered the morbidity due to injury of the FN. Methods: All data, from all the patients who underwent Parotidectomy in our unit (conducted or supervised by a single surgeon) in the Department of General Surgery, IPGMER and SSKM Hospital, Kolkata, between March 2014 to March 2019, using our novel technique for identification and protection of FN, was retrospectively analysed. Outcome measurement was expressed in terms of type of surgery, duration, estimated blood loss, any intra-operative or post-operative complications, length of hospital stay, duration of drain in place, Histopathological (HPE) reports, size of the tumour, margin and lymph node status, Facial Nerve weakness and other complications. Results: Total 13 patients underwent Parotidectomy (Total or Superficial) following our technique of identifying and protecting Facial Nerve (FN). Four of them had temporary FN paresis in immediate post-op period. None of the patients had FN paresis on follow-up at 1 year. Conclusion: The novel technique described in our study for identification and protection of FN is a promising technique for Parotid Surgery.
