An evaluation of the effects of adenoidectomy on voice and speech function in children.

Objectives: This study aims to evaluate the possible effects of adenoidectomy on voice and speech function.

Patients And Methods: Thirty-six children (20 boys, 16 girls; mean age 8.22±1.

Ghrelin levels in children with adenoid or chronic tonsil hypertrophies before and after surgery.

Objective: We aimed to evaluate the ghrelin levels in the children with adenoid or tonsil hyperthrophies.

Methods: The study included 27 children (17 boys and 10 girls). Mean age was 6.

Evaluation of HLA-A, -B, -Cw, and -DRB1 alleles frequency in Turkish patients with nasal polyposis.

Objective: To evaluate whether there is a relationship between HLA-A, -B, -Cw, and -DRB1 alleles and developing nasal polyposis (NP).

Study Design: Data from 66 patients with NP were compared with data from 100 healthy randomly selected controls. Asthma, ASA (acetylsalicylic acid) triad, polyp score, and previous sinonasal surgery were also recorded.

Relation of glutathione S-transferase genotypes (GSTM1 and GSTT1) to laryngeal squamous cell carcinoma risk.

The purpose of the present study was to investigate GSTM1 and GSTT1 genotypes by using multiplex polymerase chain reaction (PCR) in patients with laryngeal squamous cell carcinoma (LSCC). The genotypes of 110 patients with LSCC and of 197 healthy subjects as the control group were determined by PCR analysis for GSTM1 and GSTT1 genes. Results showed that frequencies of GSTM1-null, GSTT1-null, and both GSTs-null genotypes were 51.

Frequency of pharyngeal reflux in children with adenoid hyperplasia.

Objectives: The purpose of the study is to investigate whether there is any association between pharyngeal reflux and adenoid hyperplasia by using 24-h esophageal pH monitoring with a dual probe in children.

Methods: The study group consisted of 30 children with adenoid hyperplasia, and the control group consisted of 12 healthy children, studied prospectively. All children underwent 24-h esophageal pH monitoring with a dual probe (distal and proximal esophageal pH monitoring).

Increased expression of epidermal growth factor receptors in the tracheal epithelia after topical mitomycin-C in rabbits.

The aim is to examine histopathological changes and expression of epidermal growth factor receptor (EGFR) in tracheal epithelia caused by application of topical mitomycin-C (MMC) in rabbit model after the tracheotomy procedure. The conventional tracheotomy was performed in 16 rabbits. They were randomly divided into two equal groups.

Pharyngeal reflux in children with chronic otitis media with effusion.

Objective: To investigate whether there is an association between chronic otitis media (COM) with effusion and pharyngeal reflux in children by using 24-h pH monitoring with a dual probe.

Material And Methods: This was a prospective study. The study group consisted of 25 children with COM with effusion and the control group comprised 12 healthy children.

Micronucleus frequency in acquired middle ear cholesteatoma.

Objective: To determine the micronucleus (MN) frequency of acquired cholesteatoma tissue using an MN assay.

Material And Methods: Eighteen patients were diagnosed as having chronic otitis media with acquired cholesteatoma and were divided into primary and secondary acquired cholesteatoma groups. Cholesteatoma tissue and normal tissue specimens from the external ear canal skin were taken from the patients during surgical operations.
