Objective: Neurinomas of the hypoglossal nerve are very rare. They are mostly located intracranially or combined intra- and extracranially, resulting in the so-called dumbbell shape. The isolated extracranial localization of the neurinoma of the hypoglossal nerve adjacent to the cranial base as described in this case report is extremely rare.
Clinical Presentation: The 23-year-old patient presented with recurring headaches. She had right-sided hypoglossal nerve palsy for approximately 5 to 6 years. Magnetic resonance imaging revealed an extracranial tumor with contact to the cranial base originating from the hypoglossal nerve.
Intervention: The tumor was extirpated surgically and verified histologically as a schwannoma of the hypoglossal nerve.
Conclusion: Pathologies of the hypoglossal nerve as such are very rare within the clinical landscape. When a tumor occurs, its shape and location must be analyzed to establish whether, or by which approach, surgical removal is feasible. Although very unusual, the mere extracranial occurrence of a hypoglossal neurinoma at the cranial base should be considered a differential diagnosis.

A 63 year old female patient presented to our office with two chief complaints, (1) severe OSA with CPAP intolerance and (2) cosmetic face and neck concerns regarding facial rhytids, jowls, and neck laxity. She was evaluated for Inspire candidacy and found to be an appropriate candidate. She underwent a combined Inspire hypoglossal nerve stimulator implant and deep plane facelift and necklift surgery to address her sleep apnea and her cosmetic concerns.

Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.

Introduction: Breathing-synchronized hypoglossal-nerve stimulation is a treatment option for suitable patients with severe obstructive-sleep-apnoea. The classical implantation technique requires three incisions: submental to place the stimulating-electrode on terminal branches of the hypoglossal-nerve, sub-clavicular to place the impulse generator, and on the lateral chest-wall to place a breathing-sensor lead. A two-incision-technique has been propagated and widely adopted whereby the respiratory-sensing-lead is placed deeper to the IPG-pocket.

The anatomical innovation of sound-producing organs, which gives rise to a wide variety of sound signals, is one of the most fundamental factors leading to the explosive speciation of modern birds. Despite being a key clue to resolving the homology of sound-controlling muscles among birds, only few studies have explored the embryonic development of syringeal muscles. Using serial histological sections and immunohistochemistry, we described the three-dimensional anatomy and development of the cartilage, muscle, and innervation pattern of the tracheobronchi in three avian species: domestic fowls, cockatiels, and zebra finches.
