Background: Marginal Mandibular nerve, a branch of facial nerve, emerges at the lower part of the anterior border of parotid gland. It supplies risorius, muscles of lower lip and chin and joins mental nerve. This nerve has an important relationship with the lower border of mandible and is likely to be damaged during procedures in or around the submandibular area and can lead to certain morbid conditions like deviation of angle of mouth, drooling of saliva and difficulty in phonation.Methods: Sixty formalin preserved specimens of head and neck were used for studying the branching pattern of marginal mandibular nerve. The present study was conducted in the department of Anatomy Govt Medical College Srinagar over a period of two and a half years from 2015 to 2017. Cadaveric dissection was also used in the study during the routine teaching of undergraduate MBBS and BDS students in the department. The photographs of the variations seen during the study were taken.Results: In Forty-seven specimens (78.33%) there was a single branch of marginal mandibular nerve, in 10 specimens (16.6%) there were two branches of marginal mandibular nerve and in three specimens (5.0%) the marginal mandibular nerve was having three branches.Conclusions: From the above study it was concluded that marginal mandibular nerve can have two or three branches. Therefore, it is advisable to take due care during surgical procedures in the lower part of face and upper part of neck to preserve marginal mandibular nerve and to ensure cosmesis and prevent morbidity.

Abstract Background This study aims to propose surgical approaches intended to localize and preserve the marginal mandibular nerve (MMN) during routinely performed head and neck surgical procedures. Main body of abstract Preservation of the functional integrity of the MMN is a critical measure in the success of orofacial surgeries involving the submandibular triangle. This study systematically reviews the anatomical description of the nerve including origin, course relative to fascial planes, relation to the parotid gland and facial pedicle, branching pattern and anastomosis of nerve and consolidate the findings of several significant studies to determine the “surgically safe” approaches to avoid iatrogenic injury to MMN. Short conclusion The systematic approaches described in this study have helped the authors precisely determine which particular MMN preserving approach to be adopted for each aspect of head and neck surgery. This has definitely enhanced the quality of surgery performed and the postoperative satisfaction of the patients.

Marginal Mandibular Nerve

AbstractIntroduction:The Hayes-Martin manoeuvre involves ligation of the posterior facial vein and superior reflection of the investing fascia below the mandible to preserve the marginal mandibular nerve. The peri-facial nodes thus remain undissected. We perform this manoeuvre routinely during modified radical neck dissection for metastatic oropharyngeal squamous cell cancer. Here, we review the oncological safety and marginal mandibular nerve preservation rates of this manoeuvre from 2004 to 2009.Method:Retrospective review of the head and neck oncology database (2004–2009) at Addenbrooke's Hospital, Cambridge, UK, a tertiary referral centre for head and neck oncology.Results:Thirty-four patients underwent modified radical neck dissection for metastatic oropharyngeal squamous cell carcinoma. The primary tumour included the tonsil in 19 cases, base of tongue in 10 and posterior pharyngeal wall in 5. The neck nodal status was N1 in 4 cases, N2a in 11, N2b in 10, N2c in 4 and N3 in 5. All patients had adjuvant radiotherapy. Median follow up was four years (range, two to five). No peri-facial nodal region recurrences were seen. Four patients had temporary marginal mandibular nerve weakness; beyond two months, no weakness was seen.Conclusion:In neck dissections for oropharyngeal squamous cell carcinoma, the marginal mandibular nerve and accompanying facial nodes can be safely preserved without oncological risk using the Hayes-Martin manoeuvre.
