Lasting marginal mandibular nerve injury following submental deoxycholic acid treatment

Introduction: Post-operative injury of the marginal mandibular branch of the facial nerve is consider a complication in neck dissection and can be related to different factors including traction, devascularisation or the conduction block due to diathermy. Material and Methods: Prospective, crossover study including patients treated bilateral selective neck dissection of level IIa during a 12 months-period, was performed to evaluate the efficacy of the Hayes-Martin manoeuvre to prevent nerve injury during the use of cold or monopolar diathermy dissection. Results: 20 patients met the inclusion criteria (40 neck dissections). Just one case of a right temporal MMN weakness in the post-operative period was observed (1/40 = 2,5%). There were no cases of permanent marginal mandibular nerve weakness using the Hayes-Martin manoeuvre Conclusion: The Hayes-Martin manoeuvre is a safe way to preserve MMN during neck dissection of level IIa, regardless of the type of dissection.

Quality Of Surgery

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.

Morbid Conditions

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.
