Laryngeal granulomas present with clinical signs and symptoms including dysphonia, hoarseness, discomfort or pain in the throat, and dyspnea. Notably, vocal granuloma, despite its name, pathologically is not a true granulomatous process. Instead, it is characterized as a reactive/reparative process where intact or ulcerated squamous epithelium is underlaid by granulation tissue or fibrosis. Although granulomas are typically of benign nature, they often require surgical treatment. Other options for treatment include proton-pump inhibitors (PPIs) and steroid inhalations, botulinum neurotoxin injection, and phonotherapy. Nearly half of the cases usually remit through clinical management involving PPIs, topical inhalant steroids, and phonotherapy.

This is a case discussing a 21-year-old male who suffered from both non-comminuted mandibular parasymphyseal and body fractures as a result of a motor vehicle accident, requiring open reduction internal fixation (ORIF) without postoperative maxillomandibular fixation (MMF). The fracture was complicated by a broken tooth root, which required extraction.

After intraoperative MMF, ORIF was performed. The parasymphyseal fracture was plated using two locking four-hole 2-mm thick miniplates utilizing two locking screws on either side of the fracture with one plate along the alveolar surface (monocortical screw) and one along the basal surface (bicortical screw). For the right body fracture, a three-dimensional locking ladder plate was used via a transbuccal trocar approach for additional exposure needed for proper screw placement. Once the hardware was secured, the patient was taken out of MMF and restoration of premorbid occlusion was confirmed. Lastly, watertight mucosal closure was performed using absorbable sutures and Dermabond (cyanoacrylate adhesive).

Coronavirus disease 2019 (COVID-19) has emerged as a worldwide pandemic, profoundly impacting healthcare systems. Despite the use of personal protective equipment, concerns remain over the potential transmission of SARS-CoV-2 for otolaryngologists. Transmission occurs via respiratory droplets and aerosolized virus particles, which are generated during specific interventions such suctioning, bone drilling, and the application of diathermy. The mastoid and middle ear mucosa are connected to the nasopharyngeal mucosa and can serve as a potential source of viral particles in an infected patient. This highlights the need for the development and implementation of strategies that minimize aerosol spread.

In this clinical case, a patient presented with a well-circumscribed lesion on her tongue, causing interference with eating as it grew. Despite its benign appearance, an initial in-office biopsy was performed and metastatic breast cancer was found.

Jaw and oral cavity involvement by metastatic disease is very rare, occurring in less than 1% of all oral malignancies. In this video, a partial glossectomy was performed to remove the lesion.

Vocal fold injection (VFI) is a treatment modality applicable to various laryngeal diseases and is successfully used as an alternative to laryngeal framework surgery. The indications for in-office VFI include vocal fold paralysis, paresis, atrophy, and scarring along with their sequelae. This video is a detailed demonstration of office-based VFI in a patient with unilateral vocal fold paralysis (UVFP), which is the most common neurologic disorder affecting the larynx.

Reconstruction of external ear defects often poses various challenges due to the complex anatomy of the ear and its significant role in overall facial aesthetics. The location of the defect independently impacts the repair as various locations present distinct, additional factors to consider during planning. Specifically, defects of the superior auricle complicate the reconstructive process, due to the role of the helical root and superior rim in providing mechanical support for facial accessories such as glasses or hearing aids. The approach to reconstruction must be systematic while also being individually tailored in order to appropriately restore both optimal cosmesis and function.

The featured case involves the reconstruction of a full-thickness superior helix and auricular defect in a patient who wears eyeglasses with a cochlear implant on the same side. The discussion highlights the complexity of superior auricular reconstruction as well as the various surgical options used and challenges encountered.

Orbital floor fractures represent common sequelae of facial trauma that may result in significant functional and aesthetic consequences. This article presents a comprehensive overview of the management of a revision case involving an orbital floor fracture, focusing on complications related to extruded, infected orbital hardware. In addition, common mistakes that involve improper placement of orbital floor implant, poor implant sizing, and lack of adequate implant fixation are discussed.

The featured case involves delayed wound healing and a sino-orbital cutaneous fistula (SOCF) due to infected orbital hardware from a previous orbital floor fracture repair. The discussion centers on preoperative planning, including the choice of surgical approach (transconjunctival with lateral canthotomy) and implant material. Intraoperative neuronavigation was utilized as an adjunctive tool to confirm the position of the newly placed orbital implant. This case provides valuable insight on preventable complications for this procedure, nuances in surgical approach, and uncommon challenges faced by providers who perform operative facial trauma repair.

Mastoidectomy involves the removal of bone and air cells contained within the mastoid portion of the temporal bone. Common indications for this procedure include acute mastoiditis, chronic mastoiditis, cholesteatoma, and the presence of tympanic retraction pockets. Mastoidectomy may also be performed as part of other otologic procedures (e.g. cochlear implantation, lateral skull base tumors, labyrinthectomy, etc.) in order to gain access to the middle ear cavity, petrous apex, and cerebellopontine angle.

The procedure involves dissecting within the confines of the mastoid cavity, which include the tegmen superiorly, the sigmoid sinus posteriorly, the bony ear canal anteriorly, and the labyrinth medially. Mastoidectomy is traditionally classified as: simple (cortical/Schwartze), radical, and modified radical/Bondy’s mastoidectomy. The procedure can also be classified based on the preservation of the posterior canal wall: canal wall up (CWU) or canal wall down (CWD).

For patients who present with bilateral severe-to-profound sensorineural hearing loss who have little-to-no benefit from conventional hearing aids, cochlear implants can restore hearing by directly stimulating the cochlear nerve.

This video demonstrates the placement of a cochlear implant. A standard mastoidectomy and facial recess approach is performed to visualize the round window niche and membrane. The round window membrane is opened, and the cochlear implant electrode is carefully inserted into the scala tympani. After several weeks, the patient returns for implant activation with a dedicated team of audiologists.

Obstructive sleep apnea (OSA) is a common condition with several effective treatment strategies centered around relieving airway obstruction. The gold standard for OSA treatment remains continuous positive airway pressure (CPAP), but other options exist.

A recent therapy developed within the past decade utilizes hypoglossal nerve stimulation (HGNS) through a surgically implanted device. As the patient inspires, the device sends an electrical impulse similar to a cardiac pacemaker. The impulse activates targeted branches of the hypoglossal nerve, leading to stimulation of muscles that protrude the tongue and open the airway posteriorly. This mechanism has been shown to reduce airway obstruction by activating these muscles during inspiration.

Along with detailing the chronological order of events, this case outlines various complex anatomical structures that are identified in order to safely and effectively implant the hypoglossal nerve stimulator.
