ABSTRACT

OBJECTIVE: To evaluate the feasibility, safety, and failure rate of Integra® Bilayer Wound Matrix (Integra) in the reconstruction of oral cavity defects. STUDY DESIGN: Retrospective cohort study. SETTING: All study information was collected from a single academic tertiary care hospital. METHODS: Subjects included adult patients who underwent oral cavity resection and immediate subsequent reconstruction with Integra® Bilayer Wound Matrix at MD Anderson Cancer Center between the years 2015 and 2020. The following variables were collected: patient's demographics, comorbidities, disease stage, treatment and reconstruction modalities, and surgical outcome from the medical records. Statistical analysis included distribution analysis for all collected parameters and Pearson's χ2 tests to find correlation between variables and take rate of Integra. RESULTS: Eighty-three patients underwent reconstruction with Integra® Bilayer Wound Matrix dressing. Average age was 66 years old. Thirty-nine patients (47%) had history of previous resections for oral cavity tumors. Fourteen patients (17%) had history of radiation therapy to the Head and Neck region. Most common pathology was invasive squamous cell carcinoma (75%) followed by dysplasia (12%). Complete wound healing with good cellular integration occurred in 83 patients (96%) with only 3 failures requiring additional surgery. Reconstruction of mandibulectomy defects was associated with increased risk of dehiscence and bone exposure (0.66, P = .03). CONCLUSION: This study shows promising results with high take rate of Integra® Bilayer Wound Matrix dressing in the reconstruction of various oral cavity defects. We encourage surgeons to adopt this technique as a viable and versatile option into the reconstruction ladder of oral cavity defects.

ABSTRACT

The nose is the most common site for nonmelanoma skin cancer. Fortunately, most skin cancer lesions on the nose are discovered early and their timely diagnosis and excision result in superficial defects that can be reconstructed with minimal impact on the aesthetics and function. Reconstruction of full-thickness defects of the nose remains a challenging endeavor for reconstructive surgeons. An organized and systematic approach is necessary to streamline the analysis, planning, and reconstruction complex nasal defects to consistently achieve optimal results. This article reviews options for reconstructing full-thickness nasal defects and highlights current advances in established techniques.

ABSTRACT

OBJECTIVE: Tongue Retaining Devices (TRD) anteriorly displace the tongue with suction forces while patients sleep. TRD provide a non-surgical treatment option for patients with Obstructive Sleep Apnea (OSA). Our objective was to conduct a systematic review of the international literature for TRD outcomes as treatment for OSA. METHODS: Three authors independently and systematically searched four databases (including PubMed/MEDLINE) through June 26, 2016. We followed guidelines set within the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS: Sixteen studies with 242 patients met criteria. The overall means±standard deviations (M±SD) for apnea-hypopnea index (AHI) decreased from 33.6±21.1/h to 15.8±16.0/h (53% reduction). Seven studies (81 patients) reported lowest oxygen saturation (LSAT), which improved from 79.8±17.5% to 83.9±8.6%. Four studies (93 patients) reported Epworth sleepiness scale (ESS), which decreased from 10.8±4.8 to 8.2±4.5, p <0.0001. Four studies (31 patients) reported Oxygen Desaturation Index (ODI) which decreased from 29.6±32.1 to 12.9±8.7, a 56.4% reduction. CONCLUSION: Current international literature demonstrates that tongue retaining devices reduce apnea-hypopnea index by 53%, increase lowest oxygen saturation by 4.1 oxygen saturation points, decrease oxygen desaturation index by 56% and decrease Epworth sleepiness scale scores by 2.8 points. Tongue retaining devices provide a statistically effective alternative treatment option for obstructive sleep apnea.
