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.

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.

TYPE II HYPOPHARYNGEAL DEFECT RECONSTRUCTION - A SINGLE INSTITUTION EXPERIENCE

SUMMARY – 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.

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.

Cheek reconstruction following facial malignant melanoma surgery with the platysma myocutaneous flap

The aim of this study was to evaluate the results of large cheek skin defect reconstruction using a superiorly based platysma myocutaneous flap accompanied by facial artery and vein preservation, following cutaneous head and neck melanoma surgery. This study offers new insight into a procedure that is a viable, but infrequently used reconstruction option. The authors report the cases of 13 consecutive patients with cheek skin defects following melanoma surgery who underwent reconstruction with a superiorly based platysma myocutaneous flap. The procedures were performed at a tertiary clinical centre and a national melanoma surgery referral centre between 2001 and 2008. According to the disease stage, eight patients underwent sentinel lymph node biopsy and five underwent comprehensive neck dissections. All of the patients were monitored for any complications related to the donor and recipient sites. Minor venous congestion of the flap was noted in two patients, with minor marginal skin necrosis in one patient. None of the patients had donor site complications. The superiorly based platysma flap proved to be a safe and reliable option for large cheek defect reconstruction, especially considering that it is a single-stage reconstruction procedure ensuring excellent colour-matching and low donor site morbidity.
