Correlation between clinical and MRI assessment of depth of invasion in oral tongue squamous cell carcinoma.

BACKGROUND: Neck metastasis is the most important prognostic factor in oral cavity squamous cell carcinomas (SCC). Apart from the T- stage, depth of invasion has been used as a highly predictable factor for microscopic neck metastasis, despite the controversy on the exact depth cut off point. Depth of invasion can be determined clinically and radio logically. However, there is no standard tool to determine depth of invasion preoperatively. Although MRI is used widely to stage the head and neck disease, its utility in depth evaluation has not formally been assessed. OBJECTIVE: To compare preoperative clinical and radiological depth evaluation in oral tongue SCC using the standard pathological depth. To compare clinical and radiological accuracy between superficial (<5 mm) vs. deep invaded tumor (≥5 mm) METHODS: This prospective study used consecutive biopsy-proven oral tongue invasive SCC that presented to the University health network (UHN), Toronto. Clinical examination, radiological scan and appropriate staging were determined preoperatively. Standard pathology reports postoperatively were reviewed to determine the depth of invasion from the tumor specimen. RESULTS: 72 tumour samples were available for analysis and 53 patients were included. For all tumors, both clinical depth (r = 0.779; p < 0.001) and radiographic depth (r =0.907; p <0.001) correlated well with pathological depth, with radiographic depth correlating slightly better. Clinical depth also correlated well with radiographic depth (r = 0.731; p < 0.001). By contrast, for superficial tumors (less than 5 mm on pathological measurement) neither clinical (r = 0.333, p = 0.34) nor radiographic examination (r = - 0.211; p = 0.56) correlated with pathological depth of invasion. CONCLUSION: This is the first study evaluating the clinical assessment of tumor thickness in comparison to radiographic interpretation in oral cavity cancer. There are strong correlations between pathological, radiological, and clinical measurements in deep tumors (≥5 mm). In superficial tumors (<5 mm), clinical and radiological examination had low correlation with pathological thickness.

Outcome of oral tongue squamous cell carcinoma in patients with and without known risk factors.

BACKGROUND: Tobacco smoking and high alcohol consumption are considered major risk factors of oral tongue squamous cell carcinoma. This study compared disease outcome between patients with and without known risk factors. METHODS: Patients with oral tongue squamous cell carcinoma treated at two major medical centers from 1994 to 2008 were identified by cancer registry search. The medical files were reviewed for background-and-disease-related data, risk factors, and outcome. RESULTS: The study sample consisted of 291 patients: 175 had a history of heavy tobacco smoking and alcohol abuse and 116 did not. Comparison of the patients without risk factors between the two centers yielded no differences in background features. Men accounted for 74% of the total patients with risk factors and comprised 77% of the risk-factor group. The risk-factor group was characterized by a significantly higher mean tumor grade (p=0.0001) and greater tumor depth of invasion (p=0.022) than the non-risk-factor group. The 5-year local and regional control rates were 85.3% and 74%, respectively, with no significant difference between the groups. The 5-year overall survival rate was 68% in the risk-factor group and 64% in the non-risk-factor group (p=NS). Separate analysis of patients aged <40 years at diagnosis revealed a worse overall (p=0.015) and disease-free survival (p=0.038) in those without risk factors. CONCLUSIONS: The outcome of oral tongue carcinoma is similar in patients with and without risk factors. The worse prognosis in younger patients (<40 years) without risk factors suggests that the pathogenesis in these cases involves factors other than smoking and alcohol.

A patient- and observer-rated analysis of the impact of lateral rhinotomy on facial aesthetics.

OBJECTIVE: To determine, using patient- and observer-rated facial disfigurement measures, whether a lateral rhinotomy imparts significant aesthetic morbidity. DESIGN: Retrospective and subject-controlled study in a large, tertiary-referral, academic otolaryngology department. Twenty-one consecutive patients who had undergone lateral rhinotomy for the treatment of inverted papilloma were studied in the long-term. MAIN OUTCOME MEASURES: Scores on the following: (1) the novel Patient-Rated Facial Disfigurement Analogue Scale questionnaire and (2) the reliable and validated Observer-Rated Facial Disfigurement 9-Point Likert Scale. RESULTS: Patients rated their facial appearance as minimally altered and significantly less apparent to others. The observers in this study, a surgeon (J.C.I.) and a psychiatrist (M.R.K.), rated the patients' facial disfigurement as minimally visible. Patients seem to rate how apparent their appearance is to others in a similar fashion to observers. The observer-rated facial disfigurement scale used is valid and reliable. CONCLUSION: Patient- and observer-rated facial disfigurement measures suggest that a lateral rhinotomy does not impart significant aesthetic morbidity.

Resurfacing of the nasopharynx after nasopharyngectomy using a free radial forearm flap.

BACKGROUND: Nasopharyngectomy is emerging as an important treatment option for salvaging locally recurrent nasopharyngeal carcinoma (NPC). After nasopharyngectomy, resurfacing the nasopharynx and covering the internal carotid artery is important to minimize the risk of infection, osteoradionecrosis, and carotid rupture. Previous authors have advocated the use of free grafts of skin and mucosa for this purpose but have also described significant rates of partial and total graft failure. METHODS: We believe that the best and most reliable way to resurface the nasopharynx is with vascularized tissue, and our preference is for the use of a free radial forearm flap. To illustrate our approach, we present two patients who underwent nasopharyngectomy by means of a maxillary swing approach and who had resurfacing of the surgical defect with a free radial forearm flap. RESULTS: Both patients had complete en bloc resection of tumor followed by the insetting of a free radial forearm flap to reline the surgical defect. Both flaps remained completely viable, and both patients achieved successful resurfacing of the entire nasopharynx. The morbidity of surgery was minimal, and there were no perioperative complications. On assessment 1 year later, the free radial forearm flap continues to reline the entire neonasopharynx, and the long-term functional recovery after surgery is excellent. CONCLUSION: Resurfacing the nasopharynx after nasopharyngectomy with a free radial forearm flap aids healing and minimizes the risk of complications. The morbidity of surgery is minimal and the functional recovery is excellent.

Carcinoma-in-situ of the glottic larynx: results of treatment with radiation therapy.

PURPOSE: Carcinoma-in-situ (CIS) of the vocal cords frequently progresses to invasive disease if untreated. Treatment approaches include vocal cord stripping, radiation therapy (RT), and laser excision. The purpose of this analysis was to assess the efficacy and safety of a standard RT regimen in the treatment of this condition. METHODS AND MATERIALS: Between January 1980 and December 1994, 67 patients (52 men, 15 women; median age, 65 years) with glottic CIS were treated with RT. The standard RT regimen was 51 Gy in 20 fractions given over 4 weeks (99% of patients). Prior to receiving RT, 21 patients (31%) had undergone 1 or 2 vocal cord stripping procedures, and 1 had been treated with laser. RESULTS: With a median follow-up of 6.5 years, 1 patient developed invasive glottic cancer, giving a 5-year actuarial local control rate of 98%. This patient recurred 14 months after treatment and was salvaged with laryngectomy. He is currently free of disease 2 years after surgery. There were no serious acute or late treatment complications. Sixteen patients (24%) developed subsequent malignancies, 8 of these being in the upper aerodigestive tract, although none were in the radiation field. CONCLUSIONS: Moderate-dose radiation therapy is an effective treatment for glottic CIS. It is well tolerated, produces no serious acute or long-term side effects, with an excellent cure rate.

Multicentricity in papillary thyroid carcinoma: analysis of predictive factors.

OBJECTIVES: Multicentricity has been cited as a rationale for total thyroidectomy in patients with papillary thyroid carcinoma (PTC) confined to one lobe. The purpose of this study was to examine the incidence of multicentricity of PTC in a cohort of 165 patients with PTC confined to one lobe and to examine clinical and pathologic features that may help predict for the presence of contralateral disease. DESIGN: Retrospective review. SETTING: Tertiary care hospital. METHOD: A retrospective review of 165 patients with PTC confined to one lobe treated at the Toronto General Hospital from 1992 to 1997 was performed. MAIN OUTCOME MEASURE: The predictive factors affecting the presence of multicentricity of PTC were analyzed. RESULTS: The incidence of PTC present in the contralateral lobe was 56.3%. We were unable to find any correlation of multicentricity with age, sex, tumour size, extrathyroidal spread, thyroiditis, or tall cell variant of PTC. There were trends toward higher incidence of contralateral disease in those patients with a prior history of irradiation and those with lymphatic metastases, but these trends did not reach statistical significance. CONCLUSIONS: The incidence of contralateral disease in papillary thyroid cancer treated at the Toronto Hospital was 56.3%. There was a higher incidence of contralaterality in those patients with a previous history of irradiation and in those with lymphatogenous metastases, but this did not reach statistical significance.

Role of the sternocleidomastoid muscle flap preventing Frey's syndrome and maintaining facial contour following superficial parotidectomy.

The sternocleidomastoid muscle flap may play a significant role in reducing the incidence of Frey's syndrome and maintaining facial contour after parotidectomy. Patients who underwent superficial parotidectomy from August 1992 to March 1999 were divided into two groups (N = 26). One group had sternocleidomastoid muscle flap reconstruction. A historical cohort study was designed with the two groups being matched for sex, age, pathology, postoperative radiation, date of surgery, and extent of dissection. The starch iodine test was used to evaluate for gustatory sweating, and the Observer Rated Disfigurement Scale was used to assess facial contour and aesthetics. The results of our study suggest that the sternocleidomastoid flap reconstruction following parotidectomy surgery does not alter the incidence of Frey's syndrome and does not significantly improve facial contour and aesthetics.

The free vascularized flap and the flap plate options: comparative results of reconstruction of lateral mandibular defects.

OBJECTIVES/HYPOTHESIS: Reconstruction of the mandible and oral cavity after segmental resection is a challenging surgical problem. Although osteocutaneous free flaps are generally accepted to be optimal for reconstruction of anterior defects, the need for bony reconstruction for a pure lateral mandibular defect remains controversial. STUDY DESIGN: A retrospective study. METHODS: A retrospective comparative study of short- and long-term outcomes of three different reconstruction techniques for lateral defects was performed. In total, 57 patients were included, of whom 27 had a plate and pedicled pectoralis major myocutaneous flap (PMMF group), 16 had a plate and free radial forearm flap (FRFF group), and 14 had an osteocutaneous free flap. Functionality, flap failure, and complications were scored. RESULTS: Plates had to be removed in 7 of the 27 patients in the PMMF group and 2 of the 16 in the FRFF group; none of the 14 osteocutaneous free flaps failed. The difference was of borderline statistical significance (P = .055). Longterm functional outcome revealed no statistically significant difference in oral deglutition (P = .76) or in facial contour (P = .36). Oral continence was significantly better in patients in the FRFF group (88%) as compared with the PMMF group (52%) or the osteocutaneous free flap group (43%) (P = .02). On the other hand, the results for speech favored the osteocutaneous free flap group; 13 of 14 patients (92.9%) had a normal score compared with 12 of 16 patients (75%) in the FRFF group and 17 of 27 (63%) in the PMMF group. However, this represented a borderline statistically significant result (P = .06). CONCLUSIONS: For lateral mandibular defects, the osteocutaneous free flap is reliable and durable in the long term. However, in a selected group of patients either of the two flap-plate options is a viable reconstructive option.

Reconstruction of total lower lip and chin defects using the composite radial forearm--palmaris longus tendon free flap.

BACKGROUND: Functional and aesthetic restoration of total lip and chin defects can be achieved using the composite radial forearm-palmaris longus tendon free flap. OBJECTIVE: To present the technique we use and our experience with this form of reconstruction in 10 consecutive patients with total lip and chin defects who were surgically treated between 1992 and 1998. METHODS: The palmaris longus tendon acting as a sling over which the flap is draped is responsible for long-term maintenance of vertical lip height and lip support. The factors responsible for this are the long-term maintenance of vertical lip height and lip support and the transfer of facial muscle activity to the neolip. RESULTS: All patients were satisfied with their final reconstructive result. Oral competence for deglutition and speech was achieved in all patients in our case series, with no incidence of drooling. CONCLUSION: We recommend the use of the composite radial forearm-palmaris longus tendon free flap for this type of reconstructive surgery. Arch Facial Plast Surg. 2000;2:53-56

Telomerase activity is upregulated in laryngeal squamous cell carcinoma.

OBJECTIVE/HYPOTHESIS: The immortalizing enzyme telomerase has been linked to carcinogenesis and is being targeted as a novel molecular marker. This study investigated telomerase expression in patients with laryngeal squamous cell carcinoma and correlated telomerase activity with conventional prognostic parameters. STUDY DESIGN: A consecutive series of patients with laryngeal squamous cell carcinoma undergoing surgical salvage for persistent or progressive disease after failed radiation therapy. METHODS: Twenty patient samples of laryngeal squamous cell carcinoma and 20 adjacent histologically normal mucosal samples were assayed using the telomeric repeat amplification protocol (TRAP) method for detection of telomerase activity. The leukemic cell line, K562, acted as a positive control and the human fibroblast line, Hs21Fs, as a negative control. A sample was classified as telomerase positive when an RNase-sensitive hexameric repeat ladder was observed. Absence of laddering was considered a negative result. RESULTS: Seventeen of 20 (85%) tumor samples and 4 of 20 (20%) adjacent histologically normal samples were telomerase positive. No statistically significant difference was observed when densitometric readings were compared by T category, tumor grade, or site (by ANOVA). CONCLUSIONS: Although telomerase activity is present in laryngeal cancer, levels of activation do not correlate with conventional parameters used for prognostication. Our study indicates that the marker may be a useful adjunctive method in the diagnosis of malignancy after radiation failure.

Reliability and validity of an observer-rated disfigurement scale for head and neck cancer patients.

BACKGROUND: Facial disfigurement is considered to be one of the most distressing aspects of head and neck cancer and its treatment, but it has been the focus of little systematic study. Existing studies have yielded conflicting results about the psychosocial impact of disfigurement. No studies to date have examined disfigurement using a valid and reliable observer-rated measure. The purpose of the current study was to examine the validity (convergent and discriminant) and the inter-rater reliability of a novel nine-point observer-rated disfigurement scale. METHODS: The sample consisted of 74 ambulatory head and neck cancer patients more than 6 months post treatment. Ratings of disfigurement were assigned independently by surgical and nonsurgical raters. Validity was assessed by comparing the association between disfigurement ratings and sociodemographic and illness treatment variables. Reliability was assessed by examining the concordance between the surgical and nonsurgical ratings. RESULTS: Disfigurement ratings were not associated with several sociodemographic variables, supporting the discriminant validity of the scale. Disfigurement was significantly related to a diagnosis of oral cancer, a history of adjunctive radiation, the type of surgical procedure performed, the degree of physical dysfunction, and the presence of postoperative complications. Observer ratings of disfigurement were significantly related to patient ratings of disfigurement. These findings support the convergent validity of the disfigurement scale. Inter-rater reliability of the scale was high (intraclass correlation coefficient =.91). CONCLUSION: The study provides preliminary evidence for the validity and inter-rater reliability of a novel nine point observer-rated disfigurement scale that may be useful in evaluating the impact of disfigurement on quality of life in head and neck cancer.

The free iliac crest and fibula flaps in vascularized oromandibular reconstruction: comparison and long-term evaluation.

BACKGROUND: A variety of free flaps have been successfully used for mandible reconstruction. This study compared the short- and long-term results of using the free iliac crest and fibula flaps. METHODS: We conducted a retrospective analysis of 117 patients who underwent mandibular reconstruction, 59 patients with iliac crest and 58 with free fibula. Accurate long-term functional assessment was possible in 31 cases in the iliac crest group and in 48 patients with fibular reconstruction. Anterior or combined anterolateral defects formed 72% and 64% in the iliac crest and fibula groups, respectively. The remainder were pure lateral defects. In both series, a skin paddle was included to provide either lining, skin cover, or both in 77% of the cases, whereas in 23% bone only was used. RESULTS: Complications included two perioperative deaths and three flap losses in the iliac crest group and five flap losses in the fibula group. Long-term functional and cosmetic assessment showed no statistically significant differences in oral continence (p > 0.9), speech (p = 0.57), and contour results (p = 0.80) between the two groups. However, oral deglutition was statistically significantly better in the fibula free flap group (p = 0.009). CONCLUSION: Although the fibula free flap is the flap of choice, the iliac crest is an excellent and reliable complementary flap for mandibular reconstruction.

A retrospective comparison of the morbidity and cost of different reconstructive strategies in oral and oropharyngeal carcinoma.

PURPOSE: Evaluate and compare the morbidity and costs of different reconstructive strategies in oral and oropharyngeal carcinoma. STUDY DESIGN: Retrospective cross-sectional. PATIENTS AND METHODS: One hundred twenty-seven consecutive patients treated surgically for oral and oropharyngeal carcinoma between 1990 and 1996 were evaluated. Sixty-three patients had segmental mandibulectomies with 30 plate-soft tissue reconstructions and 33 bone-soft tissue flaps. Sixty-four patients had soft-tissue-only reconstructions. The following outcome parameters were analyzed: operative time, intraoperative blood loss, postoperative admission length, ICU and coronary care unit admission length, surgical interventions for complications, re-admissions, and prolonged (>6 mo) gastrostomy tube feeding, and all costs within the disease-free interval. Means and standard deviations were calculated for continuous parameters. Differences among the three groups were analyzed using one-way analysis of variance. For discontinuous parameters, the chi-square test was applied. RESULTS: Longer operative time (1.8 h) and more blood loss (150 mL) for bone-soft tissue flaps were the only statistically significant findings (P<.05) between the three groups. CONCLUSION: There is no rationale for allowing presumed factors of morbidity or cost select for type of reconstruction in patients with oral and oropharyngeal carcinoma.

Supraomohyoid neck dissection. Is it diagnostic or therapeutic?

BACKGROUND: The supraomohyoid neck dissection (SOHND) is often performed in patients with cancer of the oral cavity, where there is no clinical or radiologic evidence of regional metastases. When on pathologic examination positive neck nodes are found, however, some consider it a curative operation, whereas others regard it as a staging procedure only. METHODS: We retrospectively reviewed 43 patients with cancer of the oral cavity who had a SOHND during the period from 1991 to 1994. All patients were staged as having N0 disease and had a total of 48 SOHNDs (38 unilateral, 5 bilateral). The follow-up period was at least 2 years. RESULTS: Seven of 48 N0-staged necks showed occult metastasis (15%). Two of these patients received postoperative radiotherapy. One of 7 (14%) patients with pathologic node-positive disease on the SOHND side developed recurrent ipsilateral neck disease during the follow-up period, whereas 4 (10%) recurrences developed in 41 necks that were pathologically staged as N0. Survival was 88% for patients with pathologically N0 necks versus 86% for patients with pathologically N+; disease. CONCLUSION: Supraomohyoid neck dissection is an effective staging procedure; however, in this group of patients, neck recurrence and patient survival after SOHND appear not to be related to pathology N stage. Also, SOHND with or without adjuvant radiotherapy appears to control the neck in the majority of patients, attesting to therapeutic efficacy. A prospective study is needed, however, to see if a "wait and see" policy does not achieve similar long-term outcome.

A matched control study of treatment outcome in young patients with squamous cell carcinoma of the head and neck.

OBJECTIVES/HYPOTHESIS: To determine if there is a difference in overall survival, cause-specific survival, and relapse-free rate between young patients (<40 years of age) with head and neck squamous cell carcinoma (HNSCC) and older patients (>40 years of age). STUDY DESIGN: A matched control study describing the outcome of 185 previously untreated HNSCC patients less than 40 years of age treated at the Princess Margaret Hospital, Toronto, Ontario, Canada, between 1958 and 1992. The young patient group was compared with a control group of older patients (> 40 years of age) which was selected randomly from an entire cohort of patients (n = 10,072) and matched for site, sex, and date of presentation. METHODS: The medical records were reviewed and data abstracted for demographic information, tobacco and alcohol use, family history, primary site, clinical stage, primary treatment, histology, the occurrence of residual or recurrent disease, salvage treatment, development of subsequent primaries, survival, and the eventual cause of death. The patient's TNM stage was reclassified according to American Joint Cancer Committee/Union Internationale Contre le Cancer (AJCC/UICC) 1992 criteria on the basis of the initial clinical description and staging investigations. A multivariate regression analysis was performed. To assess the importance of age as a prognostic factor for survival, the Cox proportion hazard model was used. Smoking status was also tested in the stratified Cox proportional hazard model. RESULTS: Tumor stage and treatment modalities were comparable in both groups. The 5-year, cause-specific survival in both groups was not statistically different (72% vs. 68%, P = .91). The young patient group had a significantly better 5-year overall survival compared with the older patient group (68% vs. 49%, P = .0011). Older patients developed more subsequent primary neoplasms than the younger patient population (18% vs. 8%, P = .005). There were significantly more females, an increased incidence of oral or oropharyngeal cancer, and fewer smokers in the young patient group. Smoking, however, had an important impact on outcome with all but one patient who developed a second primary in the upper aerodigestive tract having smoked. Multivariate analysis showed that only disease stage and cancer site were significant prognostic factors for survival. CONCLUSIONS: Young patients with HNSCC do not have a worse prognosis than a matched older patient group in this case-controlled study (power > 0.75 for a minimal detectable difference of 10% disease-free survival between the two groups).

Adult epiglottitis: the Toronto Hospital experience.

OBJECTIVE: This study was conducted to gain insight into the diagnosis, treatment, and outcome measures in adult patients presenting with acute epiglottitis. METHOD: A retrospective clinical study was conducted on fifty-seven consecutive adult patients presenting with acute epiglottitis over a 13-year period to The Toronto Hospital, University of Toronto. Demographic description of patient population, presenting symptoms and signs, investigations performed, treatment provided, and incidence of complications were described. RESULTS: Soft-tissue lateral neck x-rays were abnormal in 88.1% of patients tested but had a 12% false-negative rate. Indirect, direct, or flexible laryngoscopy were the most accurate investigations to establish diagnosis and were not associated with any complications. Four of 45 patients (8.9%) had positive blood cultures for Haemophilus influenzae, with the remainder demonstrating no growth, while 22% of patients (8/36) grew possible pathogenic organisms on throat culture. A rapid clinical course (< 12 hr), evidence of tachycardia, or positive pharyngeal or blood cultures were factors that selected for a group of patients requiring formal airway intervention. CONCLUSIONS: Adult epiglottitis is different from its paediatric counterpart in that organism identification is less common, the clinical course is more gradual, there is less seasonal variation, airway compromise is more uncommon, and conservative airway management can be contemplated in the selected patient. Adult epiglottitis can be managed safely with a selective approach to airway management with airway intervention for any patient with signs of critical airway compromise.

Surgical salvage after failed radiation for paranasal sinus malignancy.

OBJECTIVE: To comment on the role of surgical salvage following failed initial treatment for paranasal sinus malignancy. DESIGN: A retrospective analysis of one hundred eighty patients treated at The Princess Margaret Hospital, Toronto, from 1976 to 1993. MATERIALS AND METHODS: Thirty-four of 95 patients (36%) who failed initial treatment underwent surgical salvage. Initial therapy in this group was radiation only (n = 27) and combined therapy (n = 7). Patient, tumor, and surgical data were recorded. There were 23 T4, three T3, six T2, and two T1 carcinomas. Survival, recurrence rates, and the influence of a variety of variables on outcome were analyzed. RESULTS: Two- and 5-year overall actuarial survival calculated from the date of diagnosis was 54% and 35%, respectively. Two- and 5-year overall actuarial survival calculated from the date of salvage surgery was 44% and 22%, respectively. Advanced age (P < .004), patients with T4 category disease (P < .04), and squamous cell carcinomas (P < .049) correlated with poorer outcome on univariate analysis. Local failure was the most common cause of death (n = 13; 65%). CONCLUSION: Salvage surgery has a limited role in the management of persistent or progressive disease following failure of initial treatment. Careful postradiation surveillance with endoscopic biopsy under general anesthesia and immediate surgical resection when appropriate may improve the salvage rate.

An objective analysis of the impact of lateral rhinotomy and medial maxillectomy on nasal airway function.

OBJECTIVE: The lateral rhinotomy and medial maxillectomy procedure, while known to interrupt nasal valve supports, has not previously been reported to adversely affect nasal airway function. The purpose of this study was to utilize state-of-the-art techniques to objectively analyze the impact of this procedure on nasal airway function. DESIGN: The study design was retrospective and subject controlled. METHODS: The study population was derived from an academic, tertiary-referral, otolaryngology-head and neck surgery department with an estimated catchment population of 4 million people. Subjects included 21 consecutive, long-term postoperative patients who had undergone lateral rhinotomy and medial maxillectomy for inverted papilloma. Objective measures included vestibular cephalometric measurements, airflow rhinomanometry, and acoustic rhinometry. RESULTS: Statistically significant results reveal that although lateral rhinotomy and medial maxillectomy are associated with alar collapse, both overall nasal airflow and valve areas are increased. CONCLUSION: Lateral rhinotomy and medial maxillectomy does not adversely affect nasal airway function. This appears to be the result of concomitant resection of the functionally dominant inferior turbinate. This suggests that lateral rhinotomy performed in conjunction with operations not requiring inferior turbinectomy, such as anterior craniofacial resection, may adversely affect nasal airway function.
