Background: The primary objective of this study was to ascertain the risk factors associated with hardware complications following segmental mandibular reconstruction in head and neck cancer patients. Additionally, we sought to develop a nomogram model that enables accurate risk prediction.
Methods: Patients who underwent segmental mandibulectomy with immediate free or local regional tissue transfer between January 2016 and December 2020 were reviewed.

Objectives: The aim of this meta-analysis is to evaluate the potential benefits of postoperative radiotherapy (PORT) in patients with pN1 oral cavity squamous cell carcinoma.
Methods: A literature search through major databases was conducted until January 2023. The adjusted hazard ratio (aHR) or risk ratio (RR) with 95% confidence intervals (CIs) of different survival outcomes were extracted and pooled.
Purpose: This study aimed to evaluate quality of life (QOL) in patients with locally advanced oral cancer who underwent surgical resection followed by simultaneous double free flap reconstruction.
Methods: Institutional database was reviewed from 2015 to 2021 and prospectively collected University of Washington Quality of Life data that were extracted for patients who met the inclusion criteria. Mean, composite, and best percentage scores were computed.
Background: Oral cavity cancers requiring excision of the oral commissure and free flap reconstruction often requires commissuroplasty to manage oral incontinence. We aimed to evaluate the implications of primary versus delayed commissuroplasty on drooling, and interincisal distance outcomes in this cohort.
Methods: A retrospective query of head and neck cancer patients operated by a single surgeon from 2017 to 2020 was performed.
Background: Reconstruction of the oral cavity commonly results in trismus and lip incompetence.
Aim And Objectives: In this study, we aim to describe an innovative design of a radial forearm free flap for resurfacing bilateral buccal defects and simultaneous functional lower lip reconstruction in a single stage.
Materials And Methods: Between January 2010 and December 2019, 6 males underwent simultaneous buccal and lower lip reconstruction with a radial forearm free flap.

Background: Large defects of the lower lip pose a difficult challenge for any reconstructive surgeon. When there is limited local tissue available to resurface the defects, free flaps are the preferred option.
Aim And Objectives: We reported our experience in the reconstruction of extensive lower lip defects.
Background: Free flap monitoring is essential for postmicrosurgical management and outcomes but traditionally relies on human observers; the process is subjective and qualitative and imposes a heavy burden on staffing. To scientifically monitor and quantify the condition of free flaps in a clinical scenario, we developed and validated a successful clinical transitional deep learning (DL) model integrated application.
Material And Methods: Patients from a single microsurgical intensive care unit between 1 April 2021 and 31 March 2022, were retrospectively analyzed for DL model development, validation, clinical transition, and quantification of free flap monitoring.
Background: Marginal mandibulectomy with or without additional mandibulotomy could represent the alternatives to avoid segmental mandibulectomy in carefully selected tongue cancers.
Aim And Objectives: This study investigated a subgroup of tongue cancers with suspected involvement to the alveolar bone because of the shallow and deformed mouth floor. We aimed to compare the functional outcomes, postoperative complications, and disease control efficacy between the 2 different marginal mandibulectomy approaches, with or without additional mandibulotomy.
A newly introduced pan-immune-inflammation value (PIV) was not evaluated for its role in oral cavity squamous cell carcinoma (OSCC). In this study, the PIV was calculated with the following equation (neutrophil count × platelet count × monocyte count)/lymphocyte count from the results of the automated hematology analyzers in 853 OSCC patients from 2005 to 2017. The optimal cutoff for the preoperative PIV was 268, as determined by a receiver operating characteristic curve.

However, the prognostic value of plasma MMP-1 levels in oral cavity squamous cell carcinoma (OSCC) has yet to be elucidated. The study is the first to use a cohort of OSCC patients to assess the association of plasma MMP-1 levels with clinicopathological factors/survival outcomes in OSCC patients.

Besides, appropriate concepts can also help economical use of expensive technology or assistant tools on the patients who are necessary and beneficial. This paper provides a comprehensive approach to select reconstructive methods for oral defects following ablative surgery.

Methods: We conducted a retrospective study of all microsurgical reconstructions using superficial temporal vessels as recipient vessels in a period of 10 years.
Background: Although microvascular free flaps are commonly performed and have high success rates, postoperative oronasal fistulas or infections do occur. The authors hypothesized that a two-layer closure is effective for prevention of intraoral complications.
Methods: Patients who underwent palatal reconstruction with a microvascular free flap were evaluated retrospectively.
Background: The administration of postoperative radiotherapy remains controversial in pN1 oral cavity cancer patients without extranodal extension. The aim is to determine whether postoperative radiotherapy reduces the neck recurrence rate and improves the survival outcomes of pN1 patients.
Methods: This study consecutively enrolled 1056 patients with newly diagnosed oral squamous cell carcinoma who underwent tumor wide excision and neck dissection from September 2002 to November 2019.
Background: Dexamethasone (Dexa) is frequently administrated to patients receiving head and neck microsurgical reconstruction with nasotracheal intubation postoperatively for airway control. Infection is the greatest concern when prolonging the treatment course. We aimed to find out the relationship between flap infection and the safe dose of Dexa.

However, it can pose a great challenge to surgeons because of its anatomical variability. As the technology advances, not only septocutaneous or musculocutaneous courses of anterolateral thigh perforators but also a hybrid musculoseptocutaneous perforator pattern have been identified on computerized imaging and on cadaveric study.

Methods: Two hundred and eighteen patients who underwent midline mandibulotomy for primary tongue cancer wide excision and flap reconstruction at Chang Gung Memorial Hospital during 2014-2019.
Background: Patients who undergo total esophagectomy and gastrectomy present a challenging scenario for reconstructive surgeons. Several techniques have been described. However, the best choice is still a matter of debate.

However, the results vary due to the various methods of visual estimation and subjective interpretation. The current study is the first to use digital image analyses to evaluate the density of CD8+/CD3+ TILs in tongue squamous cell carcinoma (TSCC).
View Article and Find Full Text PDFBackground: The primary reconstruction goal for patients with laryngopharyngectomy is the restoration of esophagus, whereas voice reconstruction is less readily reconstructed. J-flap is a novel surgical technique designed to reconstruct voice and esophagus synchronously, permitting functional rehabilitation of aerodigestive tract after laryngopharyngectomy.
Objectives: This study aims to present indications, surgical steps, and outcomes of an innovative technique for synchronous reconstruction of the esophagus and voice tube with a free thigh flap (J-flaps).
Objectives: This study aimed to investigate the association between preoperative glycated hemoglobin (HbA1c) levels and the treatment outcomes of oral cavity squamous cell carcinoma (OSCC).
Methods: Three hundred and fifty-eight OSCC patients were consecutively enrolled between July 2004 and July 2016. Clinicopathological parameters and survival outcomes were analyzed following HbA1c stratification of 6.
Purpose: The present study investigated the association between perioperative hyperglycemia and the treatment and survival outcomes of patients with oral cavity squamous cell carcinoma (OSCC).
Patients And Methods: From 2004 to 2016, 385 patients with OSCC were enrolled and stratified into normoglycemic (<180 mg/dL) and hyperglycemic (≥180 mg/dL) groups. The clinicopathologic characteristics and treatment outcomes of OSCC were subsequently analyzed.
