Head and neck continued: a retrospective analysis of neck dissections from a New Zealand oral and maxillofacial surgery unit.

Aims: The aim of this study is to analyse the demographics, diagnosis, nodal yield, metastatic rates and outcomes of patients undergoing neck dissections within the Waikato Hospital Oral and Maxillofacial Surgery (OMS) Department.

Methods: All patients that underwent neck dissections under the care of OMS at Waikato Hospital between January 2016 and December 2021 were included. Data on patient demographics, diagnosis, surgery details, nodal yields, histological results and clinical outcome were collected retrospectively for analysis.

Salivary gland tumours: an epidemiological review of non-neoplastic and neoplastic pathology.

Salivary gland tumours (SGT) demonstrate geographical variation. The primary objective of this study was to determine the types, frequency, distribution, and demographics of non-neoplastic and neoplastic salivary gland pathology at Waikato Hospital, New Zealand (NZ) over a 10-year period. Following this we conducted a 10-year retrospective review of SGT epidemiology from international literature.

Microvascular reconstruction outcomes from a New Zealand Oral and Maxillofacial Surgery Unit.

The Oral and Maxillofacial Surgery (OMS) Department at Waikato District Health Board (WDHB) is the only current OMS unit within New Zealand to reconstruct oral cavity defects with microvascular free flaps. The primary objective of the study was to retrospectively analyse the demographics, outcomes and complications of free flap surgery patients at WDHB.An OMS reconstruction database was developed and data collected retrospectively.

A five-year retrospective observational study of dental presentations to Waikato Hospital's emergency department.

Aim: Within New Zealand (NZ) there is limited research concerning demographics and utilisation of the Emergency Department (ED) for dental-related conditions. The aim of this research was to identify the prevalence of dental presentations to Waikato Hospital ED, defining patient demographics, discharge diagnoses, management, and re-presentation rates.

Methods: Patients who presented to the Waikato Hospital ED from 2015 to 2019 with ICD-10 dental diagnoses were included in the study.

The Indications for Elective Neck Dissection in T1N0M0 Oral Cavity Squamous Cell Carcinoma.

Purpose: The management of the clinically node-negative neck in T1 oral cavity squamous cell carcinoma (SCC) is controversial. The purpose of this study was to investigate tumor characteristics of surgically managed patients with T1N0 oral cavity SCC and determine the possible benefits of elective neck dissection (END).

Materials And Methods: A retrospective cohort study was conducted assessing outcomes for patients with stage I oral SCC at Waikato Hospital, New Zealand, between 2008 and 2018.

Imaging of midface fractures-a retrospective study.

Aim: To determine the number of patients that received plain facial view radiographs as well as computed tomography (CT) scans in diagnosing their midface fractures.

Methods: Data was collected from our department of maxillofacial surgery trauma database. Patients with midface fractures sustained over an 18-month period were included (n=207) and further categorised into two groups; single-system facial trauma or multi-system trauma.

Fanconi anaemia and oral squamous cell carcinoma: management considerations.

Fanconi anaemia (FA) is a rare multi-system genetic disorder where patients are susceptible to the development of oral malignancies. Clinicians involved in their management should be vigilant in detecting lesions early, and an individualised treatment plan should then be formulated. Although surgery forms the mainstay of oncological treatment, adjuvant therapy can be instituted with care.

Immunohistochemistry of Five Molecular Markers for Typing and Management of Ameloblastomas: A Retrospective Analysis of 40 Cases.

Purpose: The aims of this study are to elucidate if molecular markers can be used to differentiate between the two main types of ameloblastoma (unicystic and solid/multicystic), and to determine whether a biologically 'less-aggressive' subtype exists.

Methods: A retrospective analysis of 33 solid/multicystic ameloblastomas and six unicystic ameloblastomas was completed using immunohistochemistry for five molecular markers: P16, P53, MMP-9, Survivin, and Ki-67. Tumors were graded as either negative or positive (mild, moderate, strong), and the results were related to both ameloblastoma subtypes and outcomes following treatment.

Ameloblastoma: report on two cases and review of the literature.

The ameloblastoma is a benign odontogenic tumour that is locally aggressive and tends to recur following treatment. Several variants of this tumour exist, with the solid/multicystic and unicystic variants being the most common. We present 2 cases of mandibular ameloblastoma and review the recent literature.
