Impact of great auricular nerve sacrifice on sensory disturbance after parotidectomy.

PURPOSE: To investigate the association between great auricular nerve (GAN) sacrifice during parotidectomy and postoperative sensory disturbance. MATERIALS AND METHODS: Patients who underwent parotidectomy between November 2016 and May 2020 at a single academic institution were included in this retrospective chart review. Operative notes were reviewed to determine incidence of GAN sacrifice. Prevalence of patient-reported sensory complaints in the GAN distribution and time to spontaneous resolution of symptoms were assessed. RESULTS: Of 305 parotidectomy patients, 111 (36.4%) endorsed complaints of postoperative sensory disturbances in the GAN distribution typically characterized by numbness or shooting pains. GAN sacrifice was present in 9 (8.1%) of 111 patients who experienced sensory disturbances compared to 9 (4.6%) who reported no sensory disturbances (p > 0.05). Twenty-five patients (32.5%) experienced spontaneous resolution of symptoms at their most recent follow-up at a mean of 6.2 months after onset of symptoms. Of those that experienced a sensory disturbance, GAN preservation was not significantly associated with likelihood of spontaneous recovery (p > 0.05). CONCLUSIONS: We report the largest series to date of post-operative sensory disturbance in parotidectomy patients as it relates to intraoperative GAN sacrifice. Although the relationship between GAN sacrifice and the incidence of postoperative sensory disturbance and its subsequent resolution were not significant, we continue to advocate for GAN preservation to reduce incidence of postoperative sensory disturbances.

Rate of Fat Graft Volume Loss After Parotidectomy.

BACKGROUND: Reconstruction after parotidectomy can include fat grafting, which allows for symmetry, but grafts have demonstrated volume loss over time. OBJECTIVES: To provide quantitative evidence for the rate of volume loss of fat grafts. METHODS: Patients who received parotidectomy with fat graft reconstruction at a single institution from August 2016 to October 2020 were identified. Relationships between clinical factors and the logarithmic rate of fat graft volume loss were analyzed. RESULTS: Twelve patients received parotidectomy, fat graft reconstruction, and underwent a postoperative magnetic resonance imaging (MRI) scan. Rate of fat graft volume loss was a mean of 1.8% per month (standard deviation [SD]: 2.1% per month). Total parotid fat graft volume loss was a mean of 57.4% (SD: 67.5%). The mean follow-up time was 35.5 months (range: 9-89.8 months). Correlations between body mass index (BMI), history of smoking, and history of alcohol consumption and logarithmic rates of fat graft volume loss were increased but not significantly. CONCLUSIONS: Fat grafts have the potential of 60% volume loss at approximately 1 year. If there is clinical suspicion that patients will require adjuvant radiation or have clinical factors such as a smoking or alcohol-use history, volume requirements may be even greater to maintain adequate parotid volume for aesthetic purposes.

Parenchymal infiltration and lymphoma-associated membranoproliferative pattern of glomerular injury: an unusual presentation of mantle cell lymphoma.

Lymphomatous processes have been shown to involve the kidney by direct and paraneoplastic mechanisms. Direct injury can manifest by effacement of typical parenchymal architecture by the lymphomatous infiltrate, and indirect, paraneoplastic mechanisms have been associated with a variety of glomerular lesions. Mantle cell lymphoma (MCL) has rarely been reported to be associated with both direct infiltration and/ or paraneoplastic glomerular lesions. We describe a patient with rapidly progressive glomerulonephritis whose renal biopsy showed effacement of the renal parenchyma by MCL and a membranoproliferative pattern of glomerular injury. The patient's bone marrow was also involved by MCL, and serology revealed small M-spikes and a positive rheumatoid factor. The clinicopathologic findings were consistent with a membranoproliferative pattern of glomerular injury secondary to MCL with infiltrative destruction of renal parenchyma. This case is unusual in that MCL was diagnosed on renal biopsy, that there was a two-pronged mechanism of renal injury, and that there were two separate monoclonal immunoglobulins elaborated by the lymphoma that could be associated with the glomerular injury. Although it is uncommon to make an initial diagnosis of lymphoma from a renal biopsy, it should be recognized that patients with lymphoma might develop clinically significant renal sequelae secondary to both direct and indirect mechanisms of lymphoma-mediated nephropathy.

The effect of an educational program on opioid prescription patterns in hand surgery: a quality improvement program.

PURPOSE: To assess the variability of opioid prescription patterns among hand surgeons in a single practice and to attempt to standardize postoperative prescription sizes based on the patient's surgical procedure. METHODS: We performed a preliminary chart review to assess the range of prescription sizes for 4 common hand surgery procedures. A group of hand surgeons agreed to write postoperative opioid prescriptions based on an evaluation of historical prescription patterns. An educational assist device (the pink card) was created to serve as a memory prompt and was given to physicians, midlevel practitioners, and trainees. Subsequent chart reviews of number of pills prescribed were done 3 and 15 months later. RESULTS: After implementation of the pink card, the average postoperative prescription size decreased for all 4 case types by 15% to 48%, reaching statistical significance for 2 of the procedures. Variability in prescription sizes decreased in all cases. There was a trend toward a decreasing number of prescription refills over the course of the study. There was no evidence that patients were obtaining refills from other sources within our multigroup practice. CONCLUSIONS: Although generalized opioid prescription guidelines exist, they lack specificity. Our multimodal approach using a simple educational-assist device and changes to postoperative order sets significantly affected surgeon behavior without evidence of inadequate treatment of pain. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Free Flap Donor-Site Complications and Management.

Free flap harvest will occasionally result in donor-site complications and morbidity. Most of these complications are managed simply without producing lingering effects on activities of daily living. However, some patients will sustain limb weakness, gait issues, chronic pain, and nonhealing wounds. Frank preoperative discussion between surgeon and patient is essential to maximize postoperative outcome and manage expectations. Fastidious surgical technique will help minimize the risks of hematoma, seroma, and infection, while newer techniques can help prevent some issues with wound healing, limb weakness, and sensory changes. In this article, we describe the rates of common and rare complications at free flap donor sites, as well as techniques to prevent and manage them.

The Impact of Surgical and Nonsurgical Interventions on Overall Oral, Palpebral Fissure, and Brow Height Symmetry in a Patient with Facial Synkinesis.

Background: The treatment of facial nerve synkinesis remains complex and variable. Objective: To compare oral, palpebral fissure, and brow symmetry among surgical and nonsurgical interventions in patients with facial synkinesis. Methods: Patients with facial nerve synkinesis at a single tertiary care center between 2008 and 2022 were analyzed before and after interventions using Emotrics software. Symmetry was compared among treatment combination groups (chemodenervation and rehabilitation [CR] vs. chemodenervation and surgery [CS] vs. chemodenervation, surgery, and rehabilitation [CSR]) and among surgical intervention groups (selective neurectomy [SN] vs. selective neurectomy with facelift [SnFa] vs. no surgery). Results: Of the 29 patients meeting inclusion criteria, 72.4% were female and the median age was 60.6 years (interquartile range 49.9-67.6). The median follow-up was 32.6 months; patients who received surgery had a greater follow-up time (57.4 months vs. 26.5 months, p = 0.045). The use of a trimodal approach (CSR) was associated with improved symmetry versus CR for smile angle (p = 0.021). Among surgical interventions, the greatest improvement in palpebral fissure symmetry was in patients who received SN versus no surgery (p = 0.039); the greatest improvement in smile angle was in patients who received SnFa versus no surgery (p = 0.008). Conclusion: We recommend a comprehensive approach to the management of facial synkinesis consisting of chemodenervation, rehabilitation, and surgery tailored to each patient's needs.

A randomized control trial employing infraorbital nerve stimulation as a neural distractor during nasopharyngeal swab.

INTRODUCTION: With the global COVID-19 pandemic, nasopharyngeal swabbing has become commonplace and can occasionally cause discomfort, tearing, and anxiety. OBJECTIVE: To evaluate whether using a neural distraction device during nasopharyngeal swabbing can mitigate patient discomfort. METHODS: Participants were randomized into nasal swab with vibration first (treatment-control or Tc) or nasal swab without vibration first (control-treatment or Ct). Then the swab was repeated with the opposite technique. The vibration device was used to stimulate the infraorbital nerve at the midpupillary line, while a nasopharyngeal swab was performed according to CDC protocol. After each swab, participants filled out a survey to assess pain, discomfort, and tearing. This procedure was replicated on the contralateral nostril for a total of 4 swabs and 4 surveys. RESULTS: Thirty-four subjects were included in the analysis. In the Ct group, there was a median 1.0-point decrease in pain with the use of vibration (95% CI [-1.8, -0.3], P = 0.0117), 2.5-point decrease (95% CI [-3.0, -0.8], P = 00039) in discomfort, and a 1.0-point decrease (95% CI [-2.6, -0.2] P = 0.0303) in tearing when the vibratory device was used. In the Tc group, there was a median 2.0-point decrease in pain with vibration (95% CI [ -2.7, -1.1], P < 0.0001), 2.3-point decrease in discomfort (95% CI [-3.1, -1.5], P < 0.0001), and a 1.5-point decrease in tearing (95% CI [-2.5, -0.5], P = 0.0037) when vibration was used. CONCLUSION: Vibratory stimulation of the infraorbital nerve is safe and effectively reduced pain, discomfort, and tearing during nasopharyngeal swab. Vibration is a reasonable option to minimize patient discomfort during COVID-19 or other microbiological testing.

Malignant paraganglioma presenting as a mandibular metastasis.

BACKGROUND: Metastatic paragangliomas are rare neuroendocrine tumors. Bony metastases most commonly occur in the ribs, vertebrae, and pelvis. Few cases of mandibular metastases have been reported. METHODS: A 75-year-old female presented with a 6-month history of an enlarging mandibular mass. A biopsy was consistent with a paraganglioma. RESULTS: Staging workup with 18 F-fluorodeoxyglucose positron emission tomography demonstrated 2 hypermetabolic intra-abdominal lesions adjacent to the inferior vena cava. These were confirmed as paraganglioma by biopsy and presumed as the primary lesions. The patient underwent left segmental mandibulectomy and neck dissection with osteocutaneous fibula free tissue reconstruction. CONCLUSION: A rare case of malignant paraganglioma presenting as a mandibular metastasis is described. Nuclear medicine studies for paraganglioma are reviewed.
