Critical Degree of Orbital Floor Displacement Drives Operative Repair of Zygomaticomaxillary Complex Fractures: Findings from a 10-Year Retrospective Study.

Among zygomaticomaxillary complex (ZMC) fractures presenting to a tertiary urban academic center, the authors hypothesized the presence of both clinical and radiographic predictors of operative management. The investigators conducted a retrospective cohort study of 1,914 patients with facial fractures managed at an academic medical center in New York City between 2008 and 2017. The predictor variables were based on both clinical data and features of pertinent imaging studies, and the outcome variable was an operative intervention. Descriptive and bivariate statistics were computed and the p-value was set at 0.05. In total, 196 patients sustained ZMC fractures (5.0%) and 121 (61.7%) ZMC fractures were treated surgically. All patients who presented with globe injury, blindness, retrobulbar injury, restricted gaze, or enophthalmos and a concurrent ZMC fracture were managed surgically. The most common surgical approach was the gingivobuccal corridor (31.9% of all approaches), and there were no significant immediate postoperative complications. Younger patients (38.9 ± 18 years vs. 56.1 ± 23.5 years, p < 0.0001) and patients with greater than or equal to 4 mm of orbital floor displacement were more likely to receive surgical treatment than observation (82 vs. 56%, p = 0.045), as were patients with comminuted orbital floor fractures (52 vs. 26%, p = 0.011). In this cohort, patients more likely to undergo surgical reduction were young patients with ophthalmologic symptoms on presentation and at least 4 mm displacement of the orbital floor. Low kinetic energy ZMC fractures may warrant surgical management as often as high-energy ZMC fractures. While orbital floor comminution has been shown to be a predictor for operative reduction, in this study we also demonstrated a difference in the rate of reduction based on the severity of orbital floor displacement. This may have significant implications in both the triage and selection of patients most suitable for operative repair.

Injury Patterns in Pediatric Facial Fractures Unique to an Urban Environment.

This study aimed to define better the clinical presentation, fracture patterns, and features predictive of associated injuries and need for surgery in pediatric facial trauma patients in an urban setting. Charts of patients 18 years or younger with International Classification of Disease 9th and 10th revision (ICD-9/ICD-10) codes specific for facial fractures (excluding isolated nasal fractures) at NY-Presbyterian/Weill Cornell Medical Center between 2008 and 2017 were retrospectively reviewed. Of 204 patients, most were referred to the emergency department by a physician's office or self-presented. Children (age 0-6 years) were most likely to have been injured by falls, while more patients 7 to 12 years and 13 to 18 years were injured during sporting activities (p < 0.0001). Roughly half (50.5%) of the patients had a single fracture, and the likelihood of surgery increased with greater numbers of fractures. Older patients with either orbital or mandibular fractures were more likely to undergo surgery than younger ones (p = 0.0048 and p = 0.0053, respectively). Cranial bone fractures, CSF leaks, and intracranial injuries were more common in younger patients (p < 0.0001) than older patients and were more likely after high energy injuries; however, 16.2% of patients sustaining low energy injuries also sustained cranial bone, CSF leak, or intracranial injury. In an urban environment, significant pediatric facial fractures and associated injuries may occur after nonclassic low kinetic energy traumatic events. The age of the patient impacts both the injuries sustained and the treatment rendered. It is essential to maintain a high index of suspicion for associated injuries in all pediatric facial trauma patients.

Endoscopic odontoidectomy for brainstem compression in association with posterior fossa decompression and occipitocervical fusion.

OBJECTIVE: Endonasal endoscopic odontoidectomy (EEO) is an alternative to transoral surgery for symptomatic ventral compression of the anterior cervicomedullary junction (CMJ), allowing for earlier extubation and feeding. Because the procedure destabilizes the C1-2 ligamentous complex, posterior cervical fusion is often performed concomitantly. The authors' institutional experience was reviewed to describe the indications, outcomes, and complications in a large series of EEO surgical procedures in which EEO was combined with posterior decompression and fusion. METHODS: A consecutive, prospective series of patients who underwent EEO between 2011 and 2021 was studied. Demographic and outcome metrics, radiographic parameters, extent of ventral compression, extent of dens removal, and increase in CSF space ventral to the brainstem were measured on the preoperative and postoperative scans (first and most recent scans). RESULTS: Forty-two patients (26.2% pediatric) underwent EEO: 78.6% had basilar invagination, and 76.2% had Chiari type I malformation. The mean ± SD age was 33.6 ± 3.0 years, with a mean follow-up of 32.3 ± 4.0 months. The majority of patients (95.2%) underwent posterior decompression and fusion immediately before EEO. Two patients underwent prior fusion. There were 7 intraoperative CSF leaks but no postoperative CSF leaks. The inferior limit of decompression fell between the nasoaxial and rhinopalatine lines. The mean ± SD vertical height of dens resection was 11.98 ± 0.45 mm, equivalent to a mean ± SD resection of 74.18% ± 2.56%. The mean increase in ventral CSF space immediately postoperatively was 1.68 ± 0.17 mm (p < 0.0001), which increased to 2.75 ± 0.23 mm (p < 0.0001) at the most recent follow-up (p < 0.0001). The median (range) length of stay was 5 (2-33) days. The median time to extubation was 0 (0-3) days. The median time to oral feeding (defined as, at minimum, toleration of a clear liquid diet) was 1 (0-3) day. Symptoms improved in 97.6% of patients. Complications were rare and mostly associated with the cervical fusion portion of the combined surgical procedures. CONCLUSIONS: EEO is safe and effective for achieving anterior CMJ decompression and is often accompanied by posterior cervical stabilization. Ventral decompression improves over time. EEO should be considered for patients with appropriate indications.

Postoperative Bioresorbable Chitosan-Based Dressing for Endoscopic Middle Meatal Dacryocystorhinostomy With Balloon Dilation.

PURPOSE: To evaluate the improvement in epiphora and need for surgical revision in patients with acquired nasolacrimal duct obstruction following balloon-assisted, middle meatal endoscopic dacryocystorhinostomy with chitosan-based dressing versus bioresorbable polyurethane packing versus no packing. PATIENTS AND METHODS: This was a retrospective study of consecutive adult patients seen from 2015 to 2018 with follow-up evaluation of epiphora at least 3 months after balloon-assisted, middle meatal endoscopic dacryocystorhinostomy. Patients with a history of prior punctoplasty, septoplasty, sinus surgery, or dacryocystorhinostomy of any kind were excluded. Those meeting criteria were stratified by postoperative hemostatic intervention: no packing, bioresorbable packing, and chitosan-based dressing (groups 1, 2, and 3, respectively). Procedural outcomes were graded as successes or failures based on subjective report and anatomical findings at most recent visit within an 18-month postoperative window. Instances of recommendation for revision surgery were also recorded. RESULTS: Forty-three cases (36 patients) met the abovementioned criteria. Groups 1, 2, and 3 comprised 12, 17, and 14 cases each, respectively. Average patient age was 55.3 years old, and average duration of follow-up was 6.7 months. Significant variation in outcomes was detected across the 3 groups (P = .0495), particularly between groups 1 and 3 (P = .033). Use of chitosan-based dressing trended toward reduced rates of recommendation for surgical revision (P = .203, P = .113). CONCLUSIONS: Use of chitosan-based dressing after endoscopic dacryocystorhinostomy was associated with improved subjective and anatomical outcomes. It may also contribute to less frequent need for revision surgery. Further study in a larger prospective trial is recommended.

Endoscopic endonasal approaches to the craniovertebral junction: The Otolaryngologist's perspective.

OBJECTIVE: To review indications and techniques for the endoscopic endonasal approach to the craniovertebral junction (CVJ), analyze postoperative outcomes, and discuss important technical considerations. METHODS: A retrospective analysis was performed on all patients undergoing endonasal endoscopic approaches to the CVJ from May 2007 to June 2017. Demographic information, presenting symptoms, imaging results, treatment course, postoperative functional status, and follow-up were recorded. RESULTS: There was a total of 30 patients in this series, with a mean follow-up of 11.7 months. The average age was 33.6 years (range, 5-75 years), with 18 females and 12 males. The majority of patients (n = 22, 73.3%) had Chiari malformation type 1 with basilar invagination and symptomatic cervicomedullary compression as the indication for surgery. Intraoperative cerebrospinal fluid leak (CSF) was noted in 3 cases of odontoid resection and a single case of skull base resection. There were no postoperative CSF leaks. Overall, 81% of patients resumed regular diet by post-operative day 2 (range, 0-8 days). Severe postoperative dysphagia occurred in two cases with one requiring gastrostomy tube placement and another utilizing total parenteral nutrition for support prior to eventual gastrostomy. On average, patients were extubated by postoperative day 0.93 (range 0-3 days), with 85% extubated by postoperative day 1. A tracheotomy was required in one patient. CONCLUSION: The endonasal endoscopic approach is a valuable technique for access to the CVJ with minimal disruption of respiratory and alimentary function.

A Dual Approach for the Management of Complex Craniovertebral Junction Abnormalities: Endoscopic Endonasal Odontoidectomy and Posterior Decompression with Fusion.

BACKGROUND: Ventral brainstem compression secondary to complex craniovertebral junction abnormality is an infrequent cause of neurologic deterioration in pediatric patients. However, in cases of symptomatic, irreducible ventral compression, 360° decompression of the brainstem supported by posterior stabilization may provide the best opportunity for improvement in symptoms. More recently, the endoscopic endonasal corridor has been proposed as an alternative method of odontoidectomy associated with less morbidity. We report the largest single case series of pediatric patients using this dual-intervention surgical technique. The purpose of this study was to evaluate the surgical outcomes of pediatric patients who underwent posterior occipitocervical decompression and instrumentation followed by endoscopic endonasal odontoidectomy performed to relieve neurologic impingement involving the ventral brainstem and craniocervical junction. METHODS: Between January 2011 and February 2017, 7 patients underwent posterior instrumented fusion followed by endonasal endoscopic odontoidectomy at our unit. Standardized clinical and radiological parameters were assessed before and after surgery. A univariate analysis was performed to assess clinical and radiologic improvement after surgery. RESULTS: A total of 14 operations were performed on 7 pediatric patients. One patient had Ehlers-Danlos syndrome, 1 patient had a Chiari 1 malformation, and the remaining 5 patients had Chiari 1.5 malformations. Average extubation day was postoperative day 0.9. Average day of initiation of postoperative feeds was postoperative day 1.0. CONCLUSIONS: The combined endoscopic endonasal odontoidectomy and posterior decompression and fusion for complex craniovertebral compression is a safe and effective procedure that appears to be well tolerated in the pediatric population.

Complex odontoma of the nasal cavity: a case report.

We describe the case of a 76-year-old man who presented with symptoms of chronic nasal obstruction and recurrent sinusitis of many years' duration. The patient's history and radiographic findings established a diagnosis of a complex odontoma of the nasal cavity. The mass was surgically excised, and the diagnosis was confirmed by histopathology. The occurrence of an odontoma in the nasal cavity is extremely rare.

Quality of Life After Combined Endonasal Endoscopic Odontoidectomy and Posterior Suboccipital Decompression and Fusion.

BACKGROUND: Basilar invagination can result from systemic diseases that can weaken structural integrity of the craniocervical junction. Definitive treatment often requires ventral decompression and posterior decompression and fusion. Endonasal odontoidectomy is a relatively new minimal access procedure; quality of life (QOL) after this procedure has not been reported. METHODS: We reviewed a consecutive database of endonasal odontoidectomy cases and identified patients having posterior decompression and fusion. Two QOL questionnaires were administered postoperatively: Sino-Nasal Outcome Test and 36-Item Short Form Survey. Comparisons with other endonasal or Chiari procedures were performed. RESULTS: The study comprised 14 patients; 79% had Chiari malformation in addition to basilar invagination. Mean follow-up was 17.2 months. Symptomatic improvement occurred in 78.6% after surgery. Average postoperative Sino-Nasal Outcome Test scores were 39.2 ± 17.93, with worst scores in areas related to fatigue and sleep patterns but not nasal function. 36-Item Short Form Survey scores were lower in areas of physical function and general health but better for emotional health and pain. Compared with patients undergoing Chiari malformation surgery without endonasal odontoid resection or fusion, patients undergoing odontoidectomy had higher QOL in areas of role emotional, emotional well-being, and pain but worse QOL in general health and role physical. CONCLUSIONS: Patients undergoing posterior decompression and fusion with endonasal odontoidectomy do well after surgery with respect to nasal function and emotional health. Patients who also have severe basilar invagination associated with systemic diseases demonstrate reduced QOL after surgery in areas of physical function and sleep leading to fatigue, irritability, and concentration difficulty, likely related to their systemic disease.

The relationship between oral malodor and volatile sulfur compound-producing bacteria.

Halitosis can be a crippling social problem, and standard dental treatments and mouthwashes often provide only temporary relief. The mouth is home to hundreds of bacterial species that produce several fetid substances as a result of protein degradation. Volatile sulfur compound (VSC)-producing bacteria colonizing the lingual dorsum have recently been implicated in the generation of halitosis. Detection of VSCs, such as methylmercaptan and hydrogen sulfite, via organoleptic and objective methods, can aid in the identification of their source. Following comprehensive evaluation for possible causes, most halitosis in patients seen in an ENT practice can be localized to the tongue. We review methods of diagnosis and treatment of oral malodor from the overgrowth of proteolytic, anaerobic, gram-negative bacteria on the crevices of the lingual dorsum. Bacteriologic analysis of biofilm and scraped specimens obtained from the lingual dorsum and other oral sites, primarily gingival pockets and tonsillar crypts, can identify VSC-producing bacteria. Porphyromonas, Prevotella, Actinobacillus, and Fusobacterium species are the most common organisms identified. Halitosis is an oral phenomenon, with almost no cases originating distal to the tonsils. Halitosis arising from the lingual dorsum secondary to overpopulated VSC-producing bacteria can be successfully managed with a combination of mechanical cleansing using tongue brushes or scrapes and chemical solutions containing essential oils, zinc chloride, and cetylpyridinium chloride.

Midline nasal and hard palate destruction in cocaine abusers and cocaine's role in rhinologic practice.

Intranasal cocaine abuse can lead to destruction of the palate and perforation of the nasal septum. The pathophysiology of cocaine-induced midline destructive lesions is multifactorial and includes local ischemia secondary to vasoconstriction, chemical irritation from adulterants put in "cut" cocaine, and infection secondary to trauma, impaired mucociliary transport, and decreased humoral and cell-mediated immunity. Cocaine abuse should be suspected in patients with a palatal or septal perforation of unknown etiology.

Regional anesthesia for office-based procedures in otorhinolaryngology.

Local and topical anesthetic techniques have long been used for office-based procedures in otorhinolaryngology. There are numerous advantages to using local and topical anesthesia for office-based procedures, including a shorter recovery period, decreased health care cost, and the maintenance of a conscious patient who can communicate with the surgeon and maintain his or her own airway during the procedure. In this manuscript, we review the local and topical anesthetic techniques that can be used for otorhinolaryngic procedures including anesthesia of the external face, ear, nose, oral cavity, nasopharynx, oropharynx, hypopharynx, and larynx.

Combined modality treatment of Ewing's sarcoma of the maxilla.

BACKGROUND: Primary bone sarcomas arising in osseous structures of the head and neck are rare. These tumors are often incompletely resected and treated with radiotherapy for local control. METHODS: We report a case of a 9-year-old girl with a maxillary Ewing's sarcoma. This patient was successfully treated with neoadjuvant chemotherapy followed by surgical resection and prosthetic reconstruction of the primary site. The surgical approach that was used consisted of a subtotal maxillectomy by means of a facial degloving approach, sparing the orbital contents and the inferior orbital rim and orbital floor. RESULTS: This approach produced excellent cosmetic, functional, and oncologic outcome. The patient remains without evidence of disease recurrence more than 4 years after surgery. CONCLUSIONS: This case illustrates a novel surgical approach to the resection of a maxillary Ewing's sarcoma and highlights the need for a multidisciplinary team approach to the management of head and neck sarcomas in children.
