Systemic Inflammatory Markers as Predictors of Postoperative Complications and Survival in Patients With Advanced Head and Neck Squamous Cell Carcinoma Undergoing Free-Flap Reconstruction.

PURPOSE: The aim of this study was to determine the prognostic value of systemic inflammatory indices as factors for postoperative complications and survival in patients with advanced stages of p16-negative head and neck squamous cell carcinoma undergoing free-flap reconstruction. METHODS: This was a retrospective cohort study. The primary predictor variables were inflammatory markers such as neutrophil, lymphocyte, monocyte, and platelet count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, lymphocyte-monocyte ratio, derived NLR, systemic immune-inflammatory index, and systemic inflammatory marker index (SIM). Multivariate regression analyses were used to measure the associations between systemic inflammatory indices and overall and disease-free survival as a primary outcome and occurrence of postoperative complications as a secondary outcome measure. RESULTS: The sample was composed of 69 male (76.67%) and 21 female (23.33%) patients, with an average age of 61.15 ± 9.79 years. The median follow-up time was 24 months, and 73 of 91 (66.43%) patients were alive during the median follow-up. Overall disease survival correlated with systemic immune-inflammation (P = .022, cutoff >1,005.3, sensitivity 67.1%, and specificity 70.6%) and SIM (P = .0001, cutoff >4.05, sensitivity 90.4%, and specificity 41.2%), preoperative platelets (P = .036, cutoff <194, sensitivity 28.8%, and specificity 94.1%), and postoperative lymphocytes (P = .012, cutoff <0.6, sensitivity 38%, and specificity 76.5%), whereas increased SIM (P = .042, cutoff >4.05, sensitivity 91.3%, and specificity 38.1%), NLR (P = .031, cutoff >13.2, sensitivity 56.9%, and specificity 60%), and preoperative platelets (P = .006, cutoff <244, sensitivity 52.3%, and specificity 76%) were associated with adverse disease-free survival. The cumulative postoperative complication rate was 34.5%, of which 13.3% accounted for major complications, whereas derived NLR (P = .013, degrees of freedom 1, χ2 test 6.161, cutoff >2.3) and postoperative lymphocytes (P = .009, DF 1, χ2 test 6.756, cutoff <1) correlated with occurrence of complications. CONCLUSIONS: Inflammatory indices as measures of inflammation-related systemic dysfunction may be associated with adverse survival in patients with head and neck squamous cell carcinoma and occurrence of postoperative complications and with specific cutoff values.

Sex- and Site-Related Significance in Cutaneous Head and Neck Melanoma.

Cutaneous head and neck melanoma is a separate subgroup of cutaneous melanoma that has a worse prognosis than other primary sites. The aim of this article is to examine the significance of sex and site of primary lesion as additional risk factors. Primary localization distribution and metastatic disease in the neck in a retrospective cohort of 159 patients with cutaneous head and neck malignant melanoma were analyzed. Men develop primary melanoma more frequently than women in the left peripheral head and neck regions (P = .0364), as well as clinically visible and occult metastatic disease in the left side of the neck (P = .0138). Patients with clinically occult regional metastatic disease showed a significantly poorer survival rate than the rest of the group that underwent elective neck dissections (P = .0270). Left-sided disease in male patients may be an additional risk factor in cutaneous head and neck melanoma. Performing elective neck dissections in high-risk patients might identify patients with occult metastatic disease and worse prognosis but does not offer any significant therapeutic benefit.

The Role of Folded Multi-Island Vertical Rectus Abdominis Myocutaneous Flap in Reconstruction of Complex Maxillectomy and Midfacial Defects.

ABSTRACT: The rationale and outcomes for reconstruction of complex maxillectomy and midfacial defects using a folded multi-island vertical rectus abdominis myocutaneous free flap (MI-VRAM) are analyzed in this study.A retrospective review of prospectively collected database was conducted on all VRAM free flaps used in head and neck reconstruction from 2013 to 2019. A total of 39 cases were identified, of which 21 patients underwent immediate VRAM flap reconstruction for complex maxillectomy and midfacial defects. Variables including age, sex, pathologic subtypes, tumor staging, type of resection, defect classification, adjuvant therapy, complications, follow-up time, and reconstructive details were collected.Single skin-island VRAM was used in 10 (47.6%) patients. Eleven (52.4%) patients required the use of folded MI-VRAM flap. In 6 (28.6%) patients a triple skin-island VRAM was used and 5 (23.8%) received a double skin-island VRAM. The average size of harvested skin paddle was 15 × 7.2 cm. Secondary flap contouring was required in 6 (28.6%) patients. There were no cases of total flap loss and no major donor site complications recorded.Folded MI-VRAM flap is a reliable method for reconstruction of complex maxillectomy and midfacial defects. It provides multiple independent skin islands with excellent plasticity and abundant volume of tissue for restoration of facial contours.

Significance of Anthropometric and Nutritive Factors in Oral and Oropharyngeal Cancer Patients Undergoing Free Flap Reconstruction.

PURPOSE: This study analyzed associations between preoperative nutritional status and the incidence of early postoperative complications as a primary outcome in patients with oral and oropharyngeal cancer undergoing free flap reconstruction. We hypothesized that preoperative nutritional status may be linked with specific complications, allowing for better preoperative risk assessment. PATIENTS AND METHODS: This longitudinal, retrospective cohort study encompassed 113 patients, all treated surgically for oral and oropharyngeal cancer in the period from March 2013 up to March 2018 in a tertiary referral center. Variables considered were preoperative and postoperative serum albumin and protein values; body mass index; waist-to-hip ratio; circumference of the neck, waist, hip, and thigh; number of cigarettes smoked per day during the 10-year period before surgery; average alcohol consumption; operative time; and postoperative albumin administration. RESULTS: Our study identified preoperative protein serum concentration (≤62 g/L), postoperative albumin administration (≥200 mL), number of cigarettes smoked per day (>20), and prolonged operative time (≥450 minutes) to be associated with postoperative complications. CONCLUSIONS: This is the first study reporting cutoff values of clinical significance in assessing patient preoperative nutritional status in light of reducing postoperative complications after free flap reconstruction.

ACTIVE MIDDLE EAR VIBRANT SOUNDBRIDGE SOUND IMPLANT.

The Vibrant Soundbridge represents a new approach to hearing improvement in the form of active implantable middle ear hearing device. Unlike conventional acoustic hearing aids, which increase the volume of sound that goes to the eardrum, the Vibrant Soundbridge bypasses the ear canal and eardrum by directly vibrating the small bones in the middle ear. Because of its design, no portion of the device is placed in the ear canal itself. The Vibrant Soundbridge has been approved by the FDA as a safe and effective treatment option for adults with moderate to severe sensorineural, conductive or mixed hearing losses who desire an alternative to the acoustic hearing aids, for better hearing. The paper presents a review of the active middle ear implant Vibrant Soundbridge, which has been also implanted at the Department of Otorhinolaryngology and Head and Neck Surgery, Sestre milosrdnice University Hospital Center, which is the Referral Center for Cochlear Implantation and Surgery of Hearing Impairment and Deafness of the Ministry of Health, Republic of Croatia.

Risks and benefits of local anesthesia versus general anesthesia in tonsillectomy.

PURPOSE: Tonsillectomy is one of the most common surgical procedures in otorhinolaryngology. Modern general anesthetic techniques have reduced surgical risks, but performing the procedure under local anesthesia may still offer significant benefit for both the patient and surgeon. This study analyzed the risks and benefits of performing tonsillectomies under local anesthesia. METHODS: This is a retrospective longitudinal cohort study analyzing postoperative bleeding rates as a primary outcome measure. Secondary outcome measures were duration of surgery, consumption of analgesics and total surgery cost. RESULTS: The study enrolled 1112 patients undergoing tonsillectomy, with 462 (41.5%) patients treated under general and 650 (58.5%) patients treated under local anesthesia. There were 12 postoperative bleeding incidents in in the local anesthesia group and 9 cases of postoperative bleeding in the general anesthesia group. No significant differences based on gender regarding quantity of intraoperative bleeding or patient age were observed between the patients undergoing local versus general anesthesia. However, significant differences were noted between the groups in analgesic consumption, (Mann-Whitney U test, p = 0.001), duration of operating room stay (Mann-Whitney U test, p = 0.001), duration of surgery (Mann-Whitney U test, p = 0.001) and cost of surgery (Mann-Whitney U test, p = 0.001). CONCLUSIONS: The incidence of postoperative bleeding is not dependent on type of anesthesia. The results suggest that tonsillectomy performed under local anesthesia is a safe alternative to tonsillectomy under general anesthesia, with significant reduction of cost and duration of surgery.

TYPE II HYPOPHARYNGEAL DEFECT RECONSTRUCTION - A SINGLE INSTITUTION EXPERIENCE.

- There are several options for hypopharyngeal reconstruction depending on defect size. Reconstructive options include primary closure, local flaps, regional axial flaps or regional intestinal flaps, and free flap transfer with skin or intestinal free flaps. The preferred method of reconstruction should minimize early postoperative complications that prolong hospital stay and/or become life threatening, ensure early restoration of function and decrease donor site morbidity. The purpose of this study was to evaluate functional outcomes of different flap reconstruction methods in type II hypopharyngeal defects. In this non-randomized retrospective cohort study, data on 31 (27 male and four female) patients were collected over a 10-year period of single institution type II hypopharyngeal defect reconstructions. The following measures of functional outcome were extracted from patient medical histories: postoperative complications (flap failure, fistula formation, donor site related complications), hospital stay in days and swallowing function after 14 days, 1 month and 6 months. There were nine patients in the radial forearm free flap (RFFF) reconstruction group, seven in the jejunum reconstruction group, and 15 in the gastric tube reconstruction group. In the RFFF group, three patients experienced flap failure; in the jejunal transfer group, no donor site morbidity was observed; whereas three patients from the gastric tube reconstruction group had minor abdominal skin wound dehiscence. Out of the 3 different reconstructive methods, RFFF was most likely to fail. The mean duration of hospital stay was 22.6 days, being shortest in the RFFF group. There were no significant differences in early postoperative swallowing function among the groups. The choice of flap used for hypopharynx reconstruction should be driven by donor site factors and functional outcomes. When assessing type II hypopharyngeal defect reconstruction results, the findings of this study suggest that free jejunal flaps and gastric tubes offer superior functional results in comparison with RFFFs.
