Risk factors for jaw osteoradionecrosis: a case control study.

There are divergences among studies regarding features associated to increased risk of osteoradionecrosis (ORN). Our objective was to identify factors that predispose to the development of ORN of the jaw. This was a retrospective, hospital-based, case-control study involving patients with head and neck cancer who had been treated with ≥ 60 Gy external radiotherapy (RT) to the jaw.

Impact of AJCC 8 pT staging in cutaneous head and neck squamous cell carcinoma in a nonselected real-world patient sample.

Objective: Our aim was to evaluate characteristics associated with worse survival and the effectiveness of AJCC 8 in a real-world cohort of HNCSCC from South Brazil.

Methods: A 10-year retrospective cohort study (2011-2020) at a tertiary care center comprising 647 HNCSCC excised from 435 patients.

Results: At multivariable analysis, ear/nose/zygomatic or periorbital site, compromised or exiguous margins, and advanced pT stage were independent factors associated to DFS, while age, pN, and loco-regional recurrence were independent factors associated to DSS.

Prevalence of p16 expression in oropharyngeal squamous cell carcinoma in southern Brazil.

Objective: Our aim was to evaluate the prevalence of human papillomavirus (HPV)-positive tumors in a cohort of patients with oropharyngeal squamous cell carcinoma (OPSCC) at a single center in southern Brazil and determine the short-term prognostic factors in this sample.

Study Design: Ninety-one consecutive patients with newly diagnosed primary OPSCC between January 2017 and December 2019 were retrospectively included. Demographic, clinical, pathologic, and survival data were collected.

Factors associated with incomplete surgical margins in basal cell carcinoma of the head and neck.

Introduction: Cutaneous basal cell carcinoma recurrence is associated with inadequate surgical margins. The frequency of and the factors associated with compromised or inadequate surgical margins in head and neck basal cell carcinoma varies.

Objective: The purpose of this study was to evaluate the clinical and pathological factors associated with inadequate surgical margins in head and neck basal cell carcinoma.

Platysma transverse myocutaneous flap: a 21 case series of an overlooked reconstructive method for facial skin defects.

Introduction: Since the first report of a platysma transverse myocutaneous flap in 1977, few articles about this flap design have been added to the literature.

Objective: Our aim is to describe our department's experience with platysma transverse myocutaneous flap.

Methods: A retrospective review of all patients undergoing platysma transverse myocutaneous flap reconstruction between 2011 and 2019.

Better outcome for parotid versus neck metastasis of head and neck cutaneous squamous cell carcinoma: a new report on reemerging data.

Introduction: Regional metastases of cutaneous head and neck squamous cell carcinoma occur in approximately 5 % of cases, being the most important prognostic factor in survival, currently with no distinction between parotid and neck metastasis.

Objective: The purpose of this study was to evaluate the prognostic features among patients with head and neck cutaneous squamous cell carcinoma exhibiting regional metastasis.

Methods: A retrospective analysis of patients with cutaneous squamous cell carcinoma who underwent parotidectomy and/or neck dissection from 2011 to 2018 at a single institution tertiary center was performed.

Total rhinectomy for nasal carcinomas.

Introduction: Total rhinectomy is an uncommon procedure for the treatment of nasal malignancies, usually reserved for locally advanced tumors. There are few case series studying total rhinectomy in the literature, reporting conflicting results about recurrence and metastasis.

Objective: Evaluate prognosis of total rhinectomy cases for malignant neoplasia in our institution.
