We investigated the relationship between paravertebral muscle cross-sectional area (PVM CSA) at the third vertebra (C3) level using computerized tomography (CT) neck images and its relationship with complications after total laryngectomy. Retrospective analysis of 60 advanced laryngeal cancer patients who underwent total laryngectomy was performed. The cross-sectional areas of paravertebral neck muscles using neck CT at C3 level images obtained preoperatively were analyzed. A significant difference in PVM CSA between complication and no complication groups, F(1, 53 = 4.319, P = .043), was identified by ANCOVA. There were no significant differences in between-subject effects: T-stage (F = 1.652, P = .204), body mass index (F = 0.889, P = .35), albumin (F = .359, P = .552), age (F = 1.623 P = .208), and smoking (F = 4.319, P = .41). The PVM CSA measured at C3 level on pretreatment CT may help identify patients at higher risk of postoperative wound complications after total laryngectomy and who may particularly benefit from preoperative optimization of nutritional status.

Background Lesions affecting sphenoid sinus lateral recess (SSLR) are difficult to visualize and manipulate through the transnasal routes, especially when the sinus is highly pneumatized. External approaches to this area involve extensive surgery and are associated with significant morbidity. The aims of this study are to present our experience with the endoscopic transpterygoid approach as a method for approaching lesions of the SSLR and to evaluate the outcomes of this procedure.Methods Clinical charts of patients who had lesions in the SSLR and who were treated at our institution from September 1998 to June 2018 were retrospectively reviewed. All these patients were managed by the endoscopic endonasal transpterygoid approach.Results Thirty-nine patients were identified. No cerebrospinal fluid leak recurrences were observed during follow-up (range: 1–19.7 years; median: 2.3 years). Hypoesthesia (temporary, 1; persistent, 4) in the region innervated by the maxillary branch of the trigeminal nerve was detected in five (12.8%) patients, while symptoms due to the Vidian nerve damage (dry eye, 3; dry nasal mucosa, 1) were present in four (10%) patients.Conclusions Although the endoscopic endonasal transpterygoid approach is an excellent corridor for dealing with lesions of the SSLR, limited rate of neurologic and lacrimal complications was observed. Potential morbidity of the intervention should be discussed during preoperative counselling.

Background: To validate the repair of frontal sinus cerebrospinal fluid (CSF) leaks with preservation of frontal sinus drainage pathway (FSDP), independently of the approach used, and to establish the indications and limits of the endoscopic approach. Methods: A retrospective evaluation of patients undergoing surgery for frontal sinus CSF leaks was performed. Demographics, indications for both endoscopic/combined endoscopic and open approaches, complications, methods for maintaining FSDP, and perioperative outcomes were examined. Results: Fifty-three patients (average age 45 years) with frontal sinus CSF leaks were treated surgically from 2000 to 2018. All CSF leak repairs were successful at the first attempt with a mean followup of 76.8 months (range 4-227 months). Etiology was spontaneous (14), traumatic (26), and iatrogenic (13). In 17 patients, a purely endoscopic approach was performed, while an endoscopic endonasal orbital transposition procedure was added in 4 out of this group. In 23 patients, a combined endoscopic and osteoplastic procedure was employed, while in 13 patients a combined craniotomy and endoscopic procedure was performed. All frontal sinuses remained patent except for 2 cranialization patients. Conclusion: With contemporary endoscopic instrumentation and techniques, endoscopic closure of frontal sinus CSF leaks even in the far superolateral wall is feasible in selected patients. However, the surgeon should consider the option of combining an external approach when required. Preserving the FSDP should be the main aim regardless of the approach.

Although the red cell distribution width has been reported as a reliable predictor of prognosis in several types of cancer, to our knowledge few reports have focused on the prognostic value of red cell distribution width in laryngeal carcinoma. We aimed to explore whether the pretreatment red cell distribution width predicted recurrence in laryngeal cancer patients is a simple, reproducible, and inexpensive prognostic biomarker. All laryngeal cancer patients who underwent curative surgery (n=132) over a 7 year study period were evaluated. Data on demographics, primary tumor site, T-stage, N-stage, histological features (differentiation; the presence of perineural/perivascular invasion), treatment group (total laryngectomy or partial laryngectomy) or adjuvant therapy (chemotherapy/radiotherapy); laboratory parameters (complete blood count, including the pre-operative red cell distribution width), and disease-free survival rates were retrospectively reviewed. All cases were divided into three groups by the red cell distribution width tertile [14.4% (75th percentile) (n=29)]. High-red cell distribution width group included more patients of advanced age, and more of those with recurrent and metastatic tumors (p=0.005, 0.048, and 0.043, respectively). Individuals with red cell distribution width >14.4% (75th percentile) had lower disease free survival rates than did those with red cell distribution width 14.4% at diagnosis were at a higher risk of locoregional recurrence (hazard ratio=5.818, 95% confidence interval (95% CI) 1.25-26.97; p=0.024) than patients with a normal red cell distribution width (<13%). We found that the pretreatment red cell distribution width was independently prognostic of disease free survival rate in patients with laryngeal cancer and may serve as a new, accurate, and reproducible means of identifying early-stage laryngeal cancer patients with poorer prognoses.
