Congenital Aural Atresia

Fifteen patients with major congenital aural atresia underwent operations using an anterior (trans-atretic bone) approach. Facial nerve monitoring was used in all cases and there were no instances of facial nerve injury. Postoperatively, two thirds of the patients had speech reception thresholds of 30 dB or better; the air conduction threshold (averaged for 500, 1,000, and 2,000 Hz) improved at least 25 dB in 80% of the patients and at least 30 dB in 60% of the patients (follow-up, 10 to 29 months). Minor revision surgery was necessary in three patients. On the basis of this series, several conclusions were made. First, one of the most important factors in proper patient selection is the degree of middle ear development on computed tomography, both in terms of size and ossicular formation. Second, every attempt should be made to keep the ossicular chain intact (versus use of a prosthesis), as this appears to optimize hearing results. Third, embryologic considerations and surgical experience predict a mobile stapes in the majority of major atresias. Lastly, facial nerve abnormalities are to be expected, especially in patients with significant microtia, but facial nerve monitoring will help minimize the risk of facial nerve injury.

Parotid Surgery

When a patient presents with a mass at the angle of the mandible, a neoplasm within the parotid gland is a strong consideration. The parotid is the largest of the salivary glands. Terminal branches of the facial nerve are found within the gland. Their functional preservation is an important goal of parotid surgery. Risks of facial nerve injury rise in reoperative procedures and resection of cancers. Surgical principles apply in parotidectomy. In addition to facial nerve injury, a numb earlobe, contour deficit, salivary fistula, and gustatory sweating should be discussed with the patient before an operation. Most lesions can be removed after identification of the main trunk of the facial nerve, but a retrograde approach after finding a peripheral branch may be required. No randomized trials support a benefit from nerve monitoring. An intact facial nerve will usually begin to function, but months of recovery time may be needed. Permanent paralysis is rare. Salivary fistulae are usually self-limited. Many methods to ameliorate the cosmetic changes after parotidectomy have been described. None has gained ascendency. This review contains 6 figures and 61 references.

Facial Nerve Schwannoma

Significance Statement Facial nerve schwannoma is extremely uncommon. Despite its rarity, it is considered the most common facial nerve tumor and potentially affects any segment of the nerve. Presenting symptoms vary depending on the location of the neoplasm. Tumors pertaining to the extratemporal course of the nerve mainly appear as an asymptomatic parotid mass. We present a rare case of schwannoma of the zygomatic branch of the right facial nerve that was surgically resected, without facial nerve injury.

Relevance. Various factors can cause facial neuropathy. Iatrogenic facial nerve injury in childhood and adolescence is a complicated medical, psychological and legal problem. Risk assessment of the facial nerve injury during the elective maxillofacial surgeries is required depending on the localization of the procedure. The statistical assessment is very important for the evaluation of the possible iatrogenic facial neuropathy in children and adolescents during the elective maxillofacial surgeries.Materials and methods. 715 medical records for 2017 from the Department of Pediatric Maxillofacial Surgery of the MSUMD Clinical Center for Maxillofacial, Reconstructive and Plastic Surgery were analyzed.Results. There was a risk of injury to the trunk or branches of the facial nerve during surgery in 121 cases (16,9%) for the technical complexity of the surgical approach and the pathology location.Conclusions. There is a high risk of the facial nerve injury during the elective maxillofacial surgery in children and adolescents due to the complex anatomy of the area. Intraoperative neuromonitoring is recommended to prevent iatrogenic neuropathy of the facial nerve.
